Introduction
0.1 The Avon Biodiversity Action Plan
The Avon Biodiversity Action Plan (BAP) is the over-arching conservation strategy for the
Avon area. It has been produced on behalf of the Avon Biodiversity Partnership. The
former county of Avon (here simply referred to as Avon and now also known as ‘The West
of England’) encompasses four unitary local authority areas: Bristol City, Bath and North
East Somerset, North Somerset, and South Gloucestershire. The BAP gives an overview of
nature conservation objectives in Avon as a whole and provides a ten year strategic
framework for management and enhancement of biodiversity, in-line with the UK’s
biodiversity process. It is aimed at all those organisations, groups and individuals wishing
to improve biodiversity in the area, but particularly at partnership and potential new
partnership members. The Avon BAP is the result of extensive involvement by a wide
range of local experts and organisations, ensuring that it is as comprehensive, accurate,
forward thinking and widely supported as possible.
0.2 Aims
The main aims of the Avon Biodiversity Action Plan are to:
• Provide a strategic overview of nature conservation priorities in Avon
• Identify habitats and species that are of particular value in Avon, within the national
context
• Highlight threats and issues affecting these ‘priority’ habitats and species
• Outline objectives, targets and actions to address these threats and issues
• Encourage a common approach to biodiversity conservation and sharing of best-
practice in Avon
• Encourage education and community action as an integral part of the biodiversity
process • Promote the importance of Avon’s biodiversity at a local, regional and national level
• Provide a focus for monitoring biodiversity and biodiversity action
Biological Diversity – ‘biodiversity’ – is the variety of life on earth Biological resources feed and clothe us and provide housing, medicines and spiritual nourishment. The beauty of our surroundings depends in a large part upon their diversity. Imagine the poverty of a sea without fish, a wildflower meadow without bees busy pollinating it or Wordsworth’s world without its ‘host of golden daffodils’. Practically all life forms are mutually inter-dependent. Higher life forms, and especially humans, could not exist without a complex variety of other living creatures. Destroy the ecosphere and we destroy ourselves. We have a responsibility to preserve the ecosphere and its wealth of biodiversity, not just for ourselves, but for future generations.
Introduction
0.3 The Avon Biodiversity Partnership The Avon Biodiversity Partnership was formed in 2000 with the setting up of the
steering group. It has developed to encompass a wide range of statutory and non-
statutory bodies and will provide exciting opportunities for collaborative working. The
list of partnership members is not exclusive and new partners are both welcomed and
needed, especially from the business, academic and private sectors.
The Avon Biodiversity Partnership will:
• Drive implementation of the Avon Biodiversity Action Plan
• Champion and promote local biodiversity and its distinctiveness
• Seek opportunities for joint projects
• Monitor biodiversity and biodiversity action
• Facilitate communication and sharing of best-practice and skills • Provide a single point of contact for the many people and organisations with an
interest in nature conservation in Avon
• Support key local conservation projects and activities
• Report back annually on its achievements
• Feed into regional and national BAP processes where necessary

Chapter 1: Setting the scene
1.1 History of the biodiversity process 1.1.1 The global perspective In 1992 the UK was one of over 150 countries to sign the Convention on Biological
Diversity at the United Nations Conference on Environment and Development (The
Earth Summit) in Rio de Janeiro. This convention importantly requires countries to
develop national strategies for the conservation of biological diversity and the
sustainable use of biological resources. The Earth Summit was the largest ever
gathering of World leaders, demonstrating the high priority of environmental concerns
on the World’s political agenda.
1.1.2 The UK perspective To demonstrate its commitment to the convention, the UK government published the
UK BAP in 1994, aimed at conserving and enhancing biological diversity in the UK and
contributing to the conservation of global biodiversity. As part of this, 45 UK Habitat
and 391 UK Species Action Plans were published by 1999. The UK BAP also
highlighted the importance of increasing public awareness of, and involvement in,
conserving biodiversity.
The UK Biodiversity Process is a dynamic one. Responsibility for implementing the UK
BAP was devolved from the UK to the country level with the establishment of the
Scottish Parliament and Welsh Assembly. In England, the England Biodiversity Group,
facilitated by the DEFRA Biodiversity Policy Unit is implementing the England
Biodiversity Strategy. ‘Working with the Grain of Nature: a Biodiversity Strategy for
England’ was launched in October 2002. It seeks to ensure biodiversity considerations
become embedded in all main sectors of public policy: agriculture, water and wetlands,
woodland, marine and coastal ecosystems, and urban areas. The Strategy also looks
at ways of engaging society as a whole in understanding and acting for the needs of
biodiversity and includes local and regional activity and funding and economics
amongst its cross-cutting themes.
1.1.3 Regional work The South West was the first region to establish a Regional Biodiversity Partnership
and the South West BAP was published in 1997, setting out objectives, targets and
actions for the whole region. Due to the timing of its production before a number of the
UK priority habitats had been defined, it is not well aligned with the UK BAP. A South
West Biodiversity Implementation Plan, which will redress this lack of alignment, and
look at the way forward for the South West, will be published in 2004.
Chapter 1: Setting the scene
1.1.4 Local action Biodiversity is ultimately lost or conserved at the local level. Local BAPs were identified
in the UK BAP as the means by which national and regional strategy is translated into
effective action at the local level. They provide the opportunity to reflect the values of
local people and to take into account local conditions and distinctiveness. The
progress of Local BAPs has been introduced as a headline indicator to measure the
success of the England Biodiversity Strategy. Despite this there is no direct financial
support for the production, co-ordination or implementation of the plans. The BAP
process as a whole relies on effectiveness gained by working in partnership and
innovative approaches to seeking new resources. Funding is an issue that is currently
on the regional and national agendas (e.g. with the production of a funding strategy for
the England Biodiversity Strategy).
1.2 Why the Avon area? 1.2.1 A consistent approach
The former county of Avon, now also known as ‘The West of England’, was disbanded
in 1995 into four local unitary authority (UA) areas: Bristol City, Bath and North East
Somerset, North Somerset, and South Gloucestershire. Development and Transport
planning was, however, left in the hands of a single joint body, the Joint Strategic
Planning and Transportation Unit. Many other organisations still function at an Avon-
wide, or wider, level. For example, the Avon Wildlife Trust, DEFRA, the Forestry
Commission, the Forest of Avon, the Hawk and Owl Trust, Bristol Regional
Environmental Records Centre and the Farming and Wildlife Advisory Group, to name
but a few. Some organisations function at the level of two or three Unitary Authority
areas, for example the Cotswolds AONB Partnership and the Mendip Hills AONB.
Importantly, the Avon BAP will allow these organisations to focus their limited
resources and to pursue, influence and communicate biodiversity objectives in the area
consistently.
There are many other exciting collaborative projects in the Avon area, its partnership
experience is growing and it is making real progress in joint working and developing
strategic decision-making capacity - illustrated for example by the West of England
Strategic Partnership (WESP) and the Avon Valley Partnership. The four universities in
the area - University of Bristol, University of Bath, University of the West of England
(UWE) and Bath Spa College – have also entered an exciting new collaborative phase,
working with each other, with industry and with the community. Business West works
Chapter 1: Setting the scene
at an Avon-wide level to promote business and investment and to ensure that the
growing economy brings greater equality and sustainable growth across the area. The
Avon BAP and Biodiversity Partnership will help to ensure that biodiversity objectives
are consistently represented to and considered by these groups.
1.2.2 Fitting in regionally and nationally
Planning of biodiversity action at the county level is the approach that has been
adopted in most areas of the UK. In areas where there is no county council, as is the
case in Avon, assemblages of UA areas have been grouped successfully by joint BAPs
[for example, Tees Valley (former Clevedon county: 4 UAs), Greater Manchester (10
UAs), North Merseyside, and Birmingham and Black Country]. Many of these
demonstrate the benefits of having a strong biodiversity partnership with a dedicated
co-ordinator in bringing about gains for biodiversity. Each of the counties in the South
West Region has, or is developing, a BAP. The Avon BAP will allow Avon to be
represented on an equal footing with others in regional and national processes. It will
also make it easier to communicate and work with our neighbouring counties of
Gloucestershire, Wiltshire and Somerset. The Avon Biodiversity Partnership is
represented, through the regional BAP co-ordinators’ group, on the Regional
Biodiversity Partnership, where it informs and engages with regional partners, issues
and activity.
1.3 Links to other plans and processes in the Avon area Many plans and processes in Avon are working towards similar goals and collectively
should achieve a great deal for biodiversity. The relationship between many of these
plans and processes and the Avon BAP is described here. The cascading of actions
from the Avon BAP to more local BAPs and to individual organisational plans and
projects should ensure shared objectives across Avon, flag-up opportunities for joint
projects and reduce duplication of effort in reporting as well as implementation.
1.3.1 Local biodiversity action plans The Avon BAP is an important link between the UK and local BAPs, whether at a UA or
organisational level. It does not, however, replace the need for local BAPs, through
which much of the action will be delivered. There is a great deal of local biodiversity
action planning activity in the Avon area.
Each of the UAs has its own biodiversity action planning process. At the time of writing
this plan, B&NES (the Wildthings Partnership) and NSC had completed BAPs. SGC
Chapter 1: Setting the scene
and BCC also plan to produce BAPs. The UA and Avon plans are well-aligned. The
UA BAPs and biodiversity processes have informed development of the Avon BAP and
will now act as major delivery mechanisms for it.
The Environment Agency, the British Association of Shooting and Conservation,
Wessex Water and the Highways Agency all have BAPs that operate at a broader
geographical level than Avon. Where possible these plans have been reflected in the
Avon BAP and the plans share a number of common objectives, habitats and species.
Implementation of each of these plans should complement and support implementation
of the others. For example, where land is managed by BASC members their BAP
programme, ‘Green Shoots’, can be incorporated into the actions and objectives set out
in this document and will thus help to achieve their implementation.
British Waterways is in the process of compiling a BAP programme for the Kennet &
Avon Canal. HMP Leyhill also plans to develop a BAP, covering the prison site. The
Avon Biodiversity Partnership co-ordinator attends the HMP Leyhill meetings, thus
ensuring the links between the HMP Leyhill BAP and the Avon BAP are made. These
BAPs will both be important local delivery mechanisms for the Avon BAP.
1.3.2 Other projects and strategies The Avon BAP will enable biodiversity to be more easily and consistently integrated into
other sectors’ plans and processes – for example, through the Local Strategic
Partnerships (LSPs) responsible for developing Community Strategies. Links with
Community Strategies and Local Development Frameworks are explored more fully in
section 4.2. The Avon BAP will also be delivered through the strategies and projects of
many of the individual organisations in the Avon Biodiversity Partnership, such as the
Forest of Avon’s Forest Plan, the Mendip Hills and Cotswolds AONB management
plans, the Bristol Living Rivers Project, and the Avon Wildlife Trust’s 5-year strategic
plan.
1.3.3 Communication with non-partnership members The Highways Agency has, in its corporate documentation, recognised the importance
of the partnership approach to the BAP process, although prefers to be involved in BAP
partnerships at a regional and national, rather than local, level. Similarly, the RSPB is
fully engaged in the BAP process at a regional level but does not have the resources to
be actively involved in local partnerships. Both the RSPB and the Highways Agency,
Chapter 1: Setting the scene
however, support a number of the objectives of the Avon BAP and Partnership and are
happy to get involved on an ad-hoc basis, as the need arises. The Avon Biodiversity
Partnership will keep them informed of meetings, activities and relevant projects.
Actions for the Internal Drainage Boards in North Somerset are included in the North
Somerset BAP, since their activities are confined to this area of Avon. Their action will,
of course, contribute to the biodiversity of Avon and they will be kept informed of Avon
Biodiversity Partnership activities and invited to attend relevant meetings.
Many other organisations are important deliverers or potential deliverers of biodiversity
action in the area, for example, WESP, Business West, the Universities, and many
businesses, and as such should be approached in future with regards their involvement
with the Avon Biodiversity Partnership.
1.4 The biodiversity of Avon Ecologically, Avon is exceptionally diverse for its size (1332 square km). Avon’s varied
geology results in the occurrence of a wide range of habitats, from the species-rich
calcareous grasslands of the Cotswold and Mendip Hills and the ancient woodlands of
the ridges, steep slopes and scarp faces, to the network of rhynes of the Levels and
Moors and the coastal saltmarshes of the Severn Estuary. There are 28 UK BAP
priority habitats in Avon and the area holds 19 of the 27 broad habitat types found in
the UK, as defined in the UK BAP. UK BAP broad habitats and their associated priority
habitats found within Avon are shown in table 1.1.
Avon supports a large number of plant and animal species that are regarded as
vulnerable nationally. An audit of species of particular local importance (species of
local conservation concern) carried out in 2003 (see appendix 6.1) listed over 1000
nationally important species. Of these, 47 were UK BAP species. The species of local
conservation concern included dormice, water voles, white-clawed crayfish, otters, barn
owls, horseshoe bats and a significant number of butterfly species including brown
hairstreak, chalkhill blue and various species of fritillary. Rare plant species include
round-headed leek (Bristol onion), Bristol rock-cress, the endemic Bristol whitebeam
and nationally notable plants such as lizard orchid, adder’s-tongue spearwort (found in
only two sites in the UK) and Bath asparagus. Otters are recovering across much of
Avon and pole cats are also making a recovery, spreading south from Gloucestershire.
Avon contains a number of designated and legally protected wildlife and geological
areas. These include 86 Sites of Special Scientific Interest (SSSIs), and the Gordano
Chapter 1: Setting the scene
Valley and Leigh Woods National Nature Reserves (NNRs). SSSIs that are also of
European significance include: Chew Valley Lake Special Protection Area (SPA) for
birds; Uphill Cliff, which is part of a candidate Special Area of Conservation (cSAC) for
limestone grassland; Brockley Hall Stables, and Combe Down and Bathampton Down
Mines, both of which form parts of cSACs for bats and the Avon Gorge Woodlands
cSAC. The Severn Estuary, and its tributaries, is an especially important wetland,
comprising SSSI, SPA, proposed (p)SAC and Ramsar features (see map 1.2). Many
other wildlife or geological sites are recognised as of local importance and are
protected from development as local authority designated Sites of Nature Conservation
Interest/Importance (SNCIs: in SGC, B&NES and BCC) or Wildlife Sites (WS: in NSC).
Avon also holds parts of two Areas of Outstanding Natural Beauty (AONBs) in the
Cotswolds and the Mendip Hills (see map 1.1). Other sites are designated as Local
Nature Reserves (LNRs) and, in B&NES, BCC and SGC, have dedicated ‘Wildspaces’
officers.
Table 1.1: UK BAP broad and priority habitats found within Avon. The UK Biodiversity Group has divided the whole land surface of the country and surrounding marine environment into 27 broad habitat types. These were further divided and the sub-habitats of particular importance nationally were defined as UK priority habitats. This table lists those broad and priority habitats that exist in Avon.

Chapter 2: Implementation
Much work and collaboration has gone into the preparation and production of the Avon BAP.
However, its value will be proven in the implementation phase. This chapter provides a
framework for implementation of the Avon BAP. The proposed partnership structure set out
here is a provisional one and is flexible.
One of the most valuable outcomes of developing the plan has been bringing people
together, making others aware of current activities and ideas for future collaborative
projects. An essential part of the plan’s implementation is to build upon this contact.
The Partnership’s model for implementation is that topic working groups should be set up
for each of the five topics set out in the England Biodiversity Strategy: Agriculture; Water
and Wetlands; Woodland; Marine and Coastal Ecosystems; and Urban (section 1.1.2).
Implementation of the Habitat and Species Action Plans will be co-ordinated and driven by
these groups. The topic working groups will meet annually, or as required, to:
•••• Prioritise actions for the coming year
• Discuss possible new actions and collaborative projects
• Share knowledge, experience and best-practice
• Report back on achievements
A funding sub-group will look strategically at funding the BAP process and possible joint
projects. A communications sub-group may be set up to develop the awareness-raising,
education and community aspects of the Avon BAP, as well as to look at marketing and
media. A monitoring group will look strategically at Avon’s data needs and mechanisms of
filling them. Formation of other sub-groups will also be explored, for example a geology
group to develop the geological side of the BAP.
Since it is very difficult to separate the work of each group cleanly good communication
between groups is essential. Chairs from each topic and sub-group will attend steering
group meetings, thus ensuring all are aware of, and can influence, each other’s actions. It
may also be beneficial for the whole partnership to meet annually.
In this way future action will be based on past success and the relevance and priority of
actions will be continually reviewed, keeping the implementation process, and thus the
action plans, alive.
Chapter 2: Implementation
Proposed Partnership Structure
Steering Group Meetings: 2-4 times per year
Topic and Sub-Group Meetings: 2 times per year or as required
Chairs for each of the topic and sub-groups will attend steering group meetings and will be able to influence
the activities of other groups. Partnership members and other relevant organisations will be invited to
attend any relevant meetings. Details of those organisations involved in each topic or sub-group will be
available on www.avon-biodiversity.org.uk, as well as the most up-to-date partnership structure.

Chapter 3: Indicators, reporting back and review
3.1 Indicators and targets Monitoring progress and measuring success is a vital part of the biodiversity process. In order to
aid this process, the Avon BAP has adopted those indicators from the England Biodiversity
Strategy that are most relevant to the Avon situation, and for which a measuring mechanism is
already in place (see table 3.1). The indictors are:
• The populations of wild birds
• The condition of SSSIs
• Area of land under agri-environment agreement
• Biological quality of rivers
• Progress of Avon Habitat/Species Action Plans (HAPs/SAPs)
The first four indicators above were originally derived from the Government Quality of Life Counts
indicators, used for measuring progress with sustainable development in the UK. The England
Biodiversity Strategy simply adopted those that were most relevant to biodiversity. Thus, the
Avon BAP indicators are aligned with both the England and the UK processes.
This set of indicators will only indicate success of certain aspects of the Avon BAP, not of the
whole plan. The indicators chosen reflect those that are measured currently, meaning that
monitoring them does not divert valuable resources away from on-the-ground action for
biodiversity. Development and monitoring of a more comprehensive set of indicators would
require considerable resource input and may be considered in future.
Quantified, time-limited targets in line with the UK targets have been set where possible for each
Avon HAP/SAP. Additional targets may be developed by the topic working groups where
appropriate/required.

3.2 Reporting back The Avon Biodiversity Partnership has a responsibility to report back
on progress both locally and nationally. The Avon Biodiversity
Partnership Co-ordinator will produce an annual progress report for
the Avon BAP on behalf of the partnership. This will include
information from the topic working groups and the other partnership
sub-groups as well as information gained from monitoring the
indicators. The Biodiversity Action Reporting System (BARS) will be
used to report back on action, as soon as it comes on-line.
3.3 Review of the Avon BAP The Avon BAP is a working document which, given its ten year time-scale, must adapt to
changing circumstances and respond to lessons learned through the process of implementation
and monitoring. The plan has been produced in a ring-binder format to allow changes and
additions to be made easily. A mid-term review of the whole plan will be carried out in
consultation with all partners in 2009, in the light of the results of monitoring, and in the context of
changing issues and threats. A further review, to include recommendations for the future of the
process, will be carried out in 2014, at the end of the life of the plan.
The Biodiversity Action Reporting System is a
national, web-based reporting system. This is
due to come on-line in 2004. It should provide a facility for writing progress
reports for local BAPs. This system should
therefore aid local, as well as national, reporting.
Chapter 4: Cross-cutting issues and actions
In addition to the specific actions described in the individual Habitat and Species Action Plans,
there are cross-cutting issues and actions that lie across several plans. This section outlines
these cross-cutting actions and should be read in conjunction with each Habitat and Species
Action Plan.
This section is not intended to be a complete summary of each issue. Rather, it provides a
structure for strategic action and a guide to the major issues.
The Partnership has identified 10 cross-cutting themes:
• Farming and private ownership
• Development and planning
• Water and wetlands
• Other environmental interests
• Invasive and non-native species
• Information and data
• Landscape-scale conservation
• Communications
• Recreational activity
• Funding
4.1 Farming and private ownership Much of Avon is farmland and/or is in private ownership. Many of our important species and
valuable semi-natural habitats occur on this land. Species-rich grassland, ponds, hedges and
ditches are all inextricably linked to the farming systems within which they exist and many rely
on traditional farming practices to maintain them.
Only by working with farmers and landowners is it possible for many of the biodiversity
objectives in this plan to be met. Good relationships exist between many farmers and
landowners and the Biodiversity Partnership members that work with them in Avon, such as
FWAG, DEFRA, AWT and BASC membership (much of the land in private ownership has
shooting interest and influence from BASC members). The Partnership is committed to
remaining sensitive to the needs of farmers and landowners and to working with them to
achieve gains for biodiversity.
Agri-environment schemes and other funding of conservation work are major mechanisms that
enable landowners to manage their land favourably for biodiversity.
Chapter 4: Cross-cutting issues and actions
2004 will see DEFRA starting to introduce the new Environmental Stewardship agri-
environment scheme, with first agreements in 2005. With two levels (Higher and Entry) it is
designed to bring 80% of farmers in the UK into Stewardship compared with 20% in the current
Countryside Stewardship scheme, which it replaces. The new scheme is expected to bring
major benefits for biodiversity and will help to achieve the DEFRA PSA target to reverse the
long-term decline of farmland birds by 2020.
English Nature’s Wildlife Enhancement Scheme (WES) is a funding source for works on
SSSIs. It can also be used to improve surrounding land, where this is conducive to favourable
condition of the SSSI. EN/DEFRA have a PSA target to bring 95% of SSSIs into favourable
condition by 2010. With many of these SSSIs in private ownership, this funding is an essential
mechanism for achieving the target.
The Forestry Commission is finalising details of the new England Woodland Grants Scheme
(EWGS), to be launched in April 2005. This grant will provide funding for management and
creation of woodland. Under EWGS, as was the case under the old Woodland Grant Scheme,
landowners who create woodland on improved agricultural land may be eligible for annual
payments in lieu of income from agriculture. Funding for woodland creation and management
in the Community Forest is also available from the Forest of Avon.
There will be ongoing debate nationally in the lifetime of this plan on the future of rural delivery
in the wake of the Haskins Report. The key proposal for a single ‘integrated agency’ to take
over some or all the delivery functions of DEFRA’s Rural Development Service, English Nature,
Countryside Agency and the Forestry Commission has significant long-term implications for the
Avon BAP Partnership.

4.2 Development and planning Development has caused extensive loss of wildlife habitat, particularly in the last fifty years.
With high demand for new housing and economic development, the Avon area is under
particular pressure. However, with increasing emphasis on sustainable development, with
biodiversity as a key component, the needs of biodiversity should, increasingly, be taken into
consideration when planning development. The Partnership recognises that biodiversity must
be given full consideration in the planning process, and work will be needed to ensure that this
is the case, given current reform of the planning system. Opportunities to enhance biodiversity
through the planning process and initiatives such as Sustainable Urban Drainage Systems
should be maximised.
4.2.1 Community Strategies Local Authorities have a duty under the Local Government Act 2000 to promote the
environmental, social and economic well-being of their areas. Section 4 requires them to
prepare Community Strategies the over-arching strategy identifying the key priorities for action
in a council's area. Guidance issued as part of DETR Circular 4/2001 makes clear that local
BAPs are among the elements local authorities should build upon when preparing these
Community Strategies. Local authority planning for biodiversity should be firmly linked into
Community Strategies to provide a framework to ensure biodiversity is embedded into all
activities. Local Strategic Partnerships (LSPs) lead development and implementation of these
strategies. The four UA LSPs in Avon are at different stages in production and development of
Community Strategies and work is still needed to ensure biodiversity is fully represented in
these. A useful recent brochure ‘Life-Support – incorporating biodiversity into community
strategies’ (DEFRA) shows how LSP objectives can benefit from local biodiversity. It challenges
partnerships to ask the right questions and find those with the answers.
4.2.2 The new planning system
Chapter 4: Cross-cutting issues and actions
The Government’s Planning Green Paper, ‘Planning – delivering a fundamental change’,
published in December 2001 announced that the Government intended to review all its
planning policy guidance. The Government confirmed in July 2002 that the planning system
would be reformed, including the introduction of Local Development Frameworks to replace
local plans and unitary development plans. The local development framework will comprise
development plan documents, which will form part of the statutory development plan, and
supplementary planning documents (replacing Supplementary Planning Guidance), which
provide further detail of policies and proposals in development plan documents. The
Partnership is committed to ensuring that biodiversity is fully considered in all development
plans and other locally produced policies, plans and programmes, including Community
Strategies, the Regional Spatial Strategy, Local Development Frameworks and Supplementary
Planning Documents, and in development control decisions.
4.2.3 Links between Development Frameworks and Community Strategies The Government wishes to develop effective linkages between community strategies and local
development frameworks given that both are concerned with the achievement of sustainable
development objectives. The local development framework will be a key component in the
delivery of the community strategy, setting out its spatial aspects where appropriate. In
particular, core policies in local development documents will need to take full account of the
land-use consequences of other policies and programmes relevant to the community strategy
including education, health, waste, biodiversity, recycling and environmental protection.

The Forest of Avon, in partnership with the UAs, amongst others, is producing an SPG to cover the whole of the community forest area (2004/5).
4.3 Water and wetlands Water and wetland habitats included in this plan are standing open water, reedbeds and
sedgebeds, watercourse and floodplain, coastal and floodplain grazing marsh, and estuary.
Many of these habitats represent different successional states of the same thing. Many
floodplain ditches are considerably bigger than 1m2, so would qualify as standing open water in
the definition at some times, as watercourses at others, and as reedbeds later in the
management cycle. Whilst some actions relate to specific habitats and are thus included in the
appropriate individual HAPs, other actions apply to all water and wetland habitats.

4.4 Other environmental interests Avon’s prime wildlife sites often have other conservation interests. There are strong links
between archaeological, wildlife, geological, landscape and heritage values. Geology
underpins all biodiversity. Geological exposures often occur in sites of importance for industrial
archaeology e.g. quarries and mine workings, which can also be key wildlife sites. Many
Chapter 4: Cross-cutting issues and actions
priority habitats are underlain by important archaeological features. Historic buildings, which
may be of local, regional or even national importance for their architecture, can provide habitats
for rare bats and barn owls. Management for wildlife conservation should not compromise
these other conservation interests and opportunities should be taken to protect and enhance
geological, landscape and archaeological values wherever possible. Equally, opportunities to
enhance biodiversity should be sought when land is managed for its geological, archaeological
and/or landscape interest. Occasional conflicts of interest may arise, and these are best dealt
with on an individual site basis. Given the importance of geology to biodiversity it may be
appropriate to develop the geological/earth science aspect of the Avon BAP in future.

4.5 Invasive and non-native species Invasive and non-native species are rather like weeds – they are identified as pests only when
unwanted. There is a long list of species which have been considered a threat to biodiversity in
Avon over the years - Rhododendron, sycamore, beech, Japanese knotweed, Himalayan
balsam, Australian stonecrop, deer, squirrels, bramble, signal crayfish etc. The issues behind
control of these species can be complex. For example, bramble scrub can be regarded as an
invasive species on species-rich grassland and heath and yet it is increasingly recognised as a
very valuable wildlife habitat in its own right, supporting important populations of birds and
dormice, amongst other species. Action to control invasive and non-native species should be
considered only when they are thought to be currently threatening the biodiversity value of a
key habitat or species and, importantly, when control is likely to be cost-effective. For some
species, particularly those which regenerate or breed freely over a wide area, such as
Japanese knotweed along watercourses, there are opportunities for increasing effectiveness by
co-ordinating programmes across ownerships and areas.

4.6 Information and data
Chapter 4: Cross-cutting issues and actions
Up-to-date, accessible information is essential for conservation and enhancement of
biodiversity. Without accurate, reliable knowledge of location, quality and quantity of different
habitats and species, action cannot be properly focussed.
4.6.1 Local Records Centres In the south west of England we are particularly fortunate to have full coverage of Local
Records Centres (LRCs). BRERC is an active member of the Avon Biodiversity Partnership.
Central collation, storage, manipulation and dissemination of data, such as that carried out by
the records centre, maximises its potential use. The Partnership recognises the need to
support BRERC and to provide it with biological records when possible.
4.6.2 The National Biodiversity Network/EN SW habitat mapping pilot project The National Biodiversity Network (NBN)/EN pilot habitat mapping project in partnership with
LRCs has, for the first time, GIS mapped many of the BAP priority habitats in the South West.
The NBN maps have been extremely useful in the development of the Avon BAP. They
provide our best measure of current extent of saltmarsh, Sabellaria reefs, heath, grassland and
woodland priority habitats. Habitat is mapped in four classes, depending on how closely it
matches the NBN definition of priority habitat and how old the data is:
• Definitely the priority habitat (Data less than 5 years old)
• Definitely present but unmappable (Data less than 5 years old but habitat exists as a
mosaic with another habitat in units too small to map accurately)
• Probably the priority habitat but some difficultly in interpretation (Data more than 5 years
old or some uncertainty as to whether data matches definition of habitat)
• No priority habitat but close to the definition
These classes mean that the data can be judged and used to prioritise action (for example
survey can be prioritised to ‘probably’ areas). The NBN habitat data has been combined, in a
pilot project in Avon, with information about land management in Countryside Stewardship,
AWT reserves and SSSIs, to allow an estimate of how much and where mapped priority habitat
in Avon has known favourable management. The NBN project will come to an end in 2004
and it is unclear how the maps will be updated in future. If they are updated, however, they will
become increasingly valuable and accurate and will be a very useful monitoring tool. The NBN
habitat definitions have been adopted, where possible, by the Avon BAP as they are more
detailed than those in the UKBAP.
4.6.3 Voluntary Surveying
Chapter 4: Cross-cutting issues and actions
Avon has a large number of expert voluntary wildlife surveyors and monitoring groups. Without
their expertise and enormous commitment our knowledge of habitats and species in the area
would be far poorer. The Partnership recognises the great value of volunteer surveyors and is
committed to supporting them where possible.

4.7 Landscape-scale conservation There is increasing emphasis on the need for provision of biodiversity at the landscape scale,
to address issues of fragmentation, and the long-term viability of wildlife populations.
Landscape-scale working also addresses the needs of wide-ranging species that use different
landscape elements, such as horseshoe bats.
Batscapes is an exciting landscape-scale project working, in South Gloucestershire and
B&NES, to improve whole landscapes for bats, including many priority habitats such as
hedgerows, arable farmland, watercourses and species-rich grassland.
The South West Wildlife Trusts’ Rebuilding Biodiversity Initiative (RBI) is a landscape scale
project that set out, in its first year (2003-2004), to identify core areas of habitat, capable of
supporting self-sustaining wildlife populations and conserving them in conjunction with the
wider landscape. The Wildlife Trusts are currently seeking funding to carry this project
Chapter 4: Cross-cutting issues and actions
forwards. Another such landscape-scale project is the SW Regional Biodiversity Partnership’s
development of a Nature map, identifying the existing priority habitat resource and potential
areas for restoration in the whole of the South West. The Partnership is committed to
addressing habitat restoration and creation at a landscape scale where possible. To this end,
information from RBI was used when developing the Avon Habitat Action Plans and targeting
action for the Avon priority habitats. The role of BRERC in information management will be
particularly important to the success of landscape-scale initiatives.
4.8 Communications Avon is the most populated ‘county’ in the South West. Effective communication with local
people is fundamental to the success of the Avon BAP. Public support and community
involvement are essential if solutions to conserving biodiversity that are sustainable in the long-
term are to be found.
It appears that there is a lack of understanding of the importance of biodiversity in our lives,
despite increasing awareness of the damage human activities cause globally. For this action
plan to be effective, it must contribute to closing this gap in our learning experiences.
Biodiversity education is therefore a key ingredient in the Avon BAP, encouraging individuals to
become environmentally aware and skilled in taking environmental decisions.
There must be opportunities for people to enjoy and appreciate both the common and the
special wildlife features of their immediate environment, and to become involved in looking after
them. Practical help given to communities wishing to participate in action for biodiversity can
take the form of small grants (such as Biodiversity Action Grants or awards like the ‘Millennium
Awards’ administered by Bristol Zoo 1999-2002), advice and materials.
There is currently a great deal of activity to educate and involve the public in nature
conservation in Avon. Activities include guided walks, open days, themed events,
environmental education activities with the formal education sector and practical workdays.
There is a wealth of experience and expertise in Avon and across the UK in the field of
communicating biodiversity issues to the public. The Partnership recognises the need to tap
into this resource and develop new and innovative mechanisms to ensure that everyone in
Avon has a real opportunity to experience, understand and participate in biodiversity
conservation and the Biodiversity Action Plans.
The Partnership's communications sub-group will deal with issues of education, involvement
and community action and possibly also marketing and media and develop this aspect of the
Avon BAP. This sub-group may develop a strategic framework for involving local communities
Chapter 4: Cross-cutting issues and actions
in nature conservation in Avon and increasing public understanding of the issues surrounding
biodiversity.

4.9 Recreational Activity Recreational activities are a significant way in which many people can interact with wildlife in its
natural environment. Enjoyment and appreciation of open spaces is essential for promoting an
understanding of the natural world, fostering a sense of ownership of the environment around
us and reducing any unintended loss or damage to biodiversity. Open public access to wild
areas is thus welcome in many ways; it brings people closer to wildlife and stimulates interest in
and support for biodiversity measures. However, not all habitats and species are equally
robust. For instance, human disturbance can result in trampling of fragile vegetation and
disruption to breeding birds or animals. These problems can almost always be avoided with
knowledge and forethought - for example attractive routes can be provided around wildlife
refuges rather than through them; access can be to one riverbank rather than both. The
partnership recognises the importance of managing recreational use of priority habitats in order
to minimise adverse impact on the biodiversity whilst increasing people’s appreciation of nature
conservation.

4.10 Funding
Chapter 4: Cross-cutting issues and actions
The Avon biodiversity action planning process, whilst ambitious and aspirational, should be
based on the achievable. Although much can be done to implement biodiversity action by
working within existing and shared resources, there is no doubt that many individual actions will
require additional, external funding. A strategy may be required to set out a framework that
prioritises actions that need external funding and sets out mechanisms for funding co-
ordination of the process. This strategy would propose ways of increasing funding availability
through current and new agencies, as well as sponsorship and partnership. It would require
regular review as new sources of funding became available and new actions plans are
produced.
The Partnership expects that this strategic approach will help to enable projects in many parts
of Avon, thereby also increasing the resources available to more local biodiversity partnerships
and projects.

Chapter 5: Habitat and Species Action Plans
5.0.1 Selecting Avon’s priority habitats
The UK Biodiversity Group has divided the
whole land surface of the country and
surrounding marine environment into 27
broad habitat types. These were further
divided and the sub-habitats of particular
national importance were defined as UK
priority habitats. Avon contains 19 of the 27
broad habitat types and 28 UK priority
habitats.
Avon HAPs are presented here for 22 (see table 5.0) of the 28 (see table 1.1) UKBAP priority
habitats found in Avon. A number of other habitats considered by local experts to be of particular
importance in Avon are also included in the HAPs (see table 5.0). These local priority habitats are:
• The whole arable field (not just cereal field margins)
• Sedgebeds
• All hedgerows (not just those which are ancient and/or species-rich)
• All watercourses and the floodplain
• All (not just eutrophic) standing water
The Action Plans contained in this document will no doubt increase in number as new priorities
arise and opportunities occur. In time, we hope to produce plans for all of Avon's main habitats,
including dry-stone walls, post-industrial sites and urban areas.
UK priority habitats were selected using one or more of the following criteria: • Habitats for which the UK has international obligations • Habitats at risk, such as those which are rare or have a high rate of recent decline • Habitats which are functionally important for species inhabiting wider environments • Habitats important for species of particular conservation concern.

5.0.2 Priority species in Avon An audit of Avon’s species of local conservation concern was carried out in 2003 by BRERC, in
collaboration with the Avon BAP Partnership and local experts (for details of criteria used to select
species see Appendix 6.1). This identified over 1000 Avon species, of which 46 were UK BAP
species (for annually updated audit see www.avon-biodiversity.org.uk). Whilst the majority of
species can be accommodated for by habitat level action, some transcend the bounds of single
habitats, require very specific management or are under particular threat and so warrant a separate
species action plan. These are the Avon BAP Priority Species. One of the priority species is
dormouse, a SAP for which is presented here (5a.1). Other such species, for which SAPs will be
written in future, include water vole, white-clawed crayfish, great crested newt, otter, and bat
species. This list is likely to be altered in future with changing threats and issues.
Chapter 5: Habitat and Species Action Plans
5.0.3 Development and structure of the habitat and species action plans Extensive consultation with and involvement of local experts and all organisations identified as
implementors has aimed to ensure that each action plan is as comprehensive, accurate, forward
thinking and widely supported as possible. Importantly, any action that was assigned to a particular
organisation has been agreed with that organisation in 2003/2004. The plans all follow a standard
format, similar to that of the national plans (see box 5.0).
Box 5.0: HAP/SAP layout Current status: Habitat definition and biological status of the habitat/species at the time of writing
(2003/2004). Where feasible, priority areas for action (where survey, management, restoration or re-creation is most needed) have been outlined in this section.
Current threats: Threats seen as most pertinent in 2003/4. Objectives addressing these threats are
also referenced, ensuring that the relationship between threats, objectives, targets and actions is clear.
Objectives, targets and actions: Objectives and targets with actions needed to achieve them.
Where possible a specific time has been allocated to a particular action. Targets are not included for each objective. Additional targets may be set by topic working groups where appropriate/necessary. Actions will be further prioritised on an annual basis by the topic working groups. Actions are sometimes necessarily general, giving organisations the flexibility to implement and interpret them in a way that suits them. Organisations that have agreed to implement each action are identified. The list of implementors is not exclusive and other partners are both welcomed and needed.
Species-rich grassland action plan 5.1
5.1.1 Current status 5.1.1.1 Definition For the purposes of this action plan the term species-rich grassland encompasses the three UK
priority grassland habitats that are present in Avon. These are: lowland calcareous grassland (and
associated lowland heath), lowland meadows (neutral grassland) and lowland dry acid grassland.
Lowland grasslands occur at altitudes of approximately 300 m or less in the UK. The whole of
Avon is below this level, with the highest point being Dundry Downs at 233m. Related Avon Plans:
Woodland, Wood Pasture and Parkland.
Lowland calcareous grasslands develop on shallow lime-rich soils (pH 6.5-8.5) generally
overlying limestone rocks, including chalk. In Avon, lowland calcareous grassland is found mainly
on the Mendip Hills and northward extending ridges as well as in the Avon Gorge and the
Cotswolds (see table 5.1.1 and map 5.1.1 for estimated amount). The Avon Gorge in particular is
known for rare plants such as Bristol rock-cress and round-headed leek. Importantly, Avon (at
Uphill, Purn Hill and Hellenge Hill) and parts of neighbouring Somerset hold the full extent of the
Somerset hair-grass sub-community (CG1e) of the characteristic sheep’s fescue-carline thistle
(CG1) community within the UK1.
Lowland heath is vegetation with more than 25% cover of dwarf shrubs including heathers,
bilberry and western gorse. Patches of sandy acidic soil within the species-rich grasslands
support lowland heath in parts of North Somerset (for example Goblin Combe and Dolebury
Warren). There are also some fragments on spoil heaps in South Gloucestershire and at Siston
Common and Troopers Hill in Bristol (see table 5.1.1 and map 5.1.1 for estimated amount).
Lowland meadows (neutral grassland) are found on soils (pH 5-6.5) that are deeper and less
free-draining than the limestone soils and are generally richer in nutrients. This means that
grasses, such as sweet vernal-grass, tend to be more abundant than the herbs, which can include
pepper-saxifrage and green-winged orchid. There is some very rich neutral grassland in Avon. It
occurs mainly on the hills around the Chew Valley, the lower slopes of the Cotswold and Mendip
Hills, and in South Bristol, for example at Hawkfield Meadows. In some parts of Avon, however, it
is limited to roadside verges (see table 5.1.1 and map 5.1.1 for estimated amount). Variations in
soil chemistry, moisture and management are reflected in the diversity of sward types and faunal
communities in Avon.
Lowland dry acid grasslands usually occur on soils (pH < 5) overlying acid rocks such as
sandstones and acid igneous rocks and on superficial deposits such as sands or gravel. The
sward is usually dominated by grasses and may be naturally species-poor. More diverse swards 1 Defined by the UK Biodiversity Group using the National Vegetation Classification.
Species-rich grassland action plan 5.1
are associated with sparse soils on steeper slopes. Lowland dry acid grasslands in Avon occur
over sandstone rock to the North and to the East of Bristol (see table 5.1.1 and map 5.1.1 for
estimated amount). Acid grassland has also developed on slag heaps close to Pensford and at
Troopers Hill in Bristol.
The amount of mapped habitat with known favourable management is also included in table 5.1.1
with more details on www.avon-biodiversity.org.uk.

Arable farmland action plan 5.2
5.2.1 Current status 5.2.1.1 Definition The UK BAP habitat of cereal field margins has been broadened for the context of Avon to
include the whole arable field, where it is utilised by key species. Related Avon Plans:
Hedgerows, Species-Rich Grassland, Coastal and Floodplain Grazing Marsh.
5.2.1.2 Biological status Well-managed arable farmland provides nesting and feeding sites for declining farmland birds
such as the skylark and grey partridge. Many species of butterflies, grasshoppers, plant bugs
and other invertebrates rely on arable farmland, some breeding in crops and spending the
winter in grassy banks and at the interface of crops, hedges and other features.
Even more dependent on arable farmland are the rare arable plants. Overall, some 300
species of plants can occur in arable fields. Avon has regionally important species of arable
flowers, including broad-leaved spurge, night-flowering catchfly, corn parsley, shepherd’s-
needle and narrow-fruited cornsalad. Some of these arable wild flowers are of conservation
concern because of enormous national declines in their distribution and abundance. There is
also much evidence of widespread declines in populations of farmland birds. In 2003 there
were 656 arable landholdings in Avon, with an estimated 5506 ha of arable land (DEFRA,
personal communication). The Cotswold plateau is particularly valuable for arable biodiversity,
providing an important reservoir for arable species.

Purple moor-grass and rush pasture action statement 5.3
Purple moor-grass and rush pastures occur on poorly drained, usually acidic soils in lowland areas
of high rainfall in South West England, South West Scotland and Northern Ireland. Their
vegetation consists of various species-rich types of fen, meadow and rush pasture. Purple moor-
grass and rushes, especially sharp-flowered rush, are usually abundant. Key species associated
with purple moor-grass and rush pastures include meadow thistle, curlew and snipe. There is
estimated to be 56 000 ha of purple moor-grass and rush pasture in the UK.
Purple moor-grass and rush pasture is uncommon in Avon. The sites where it is favourably
managed are Clapton, Weston and Walton moors in the Gordano Valley and Max and Yanal Bog
SSSIs. Sites with unknown management in Avon are Caswell, Tickenham, Nailsea and Kenn
Moors and some patches on Webb’s heath. Only small areas of the listed sites support this
specific habitat type. Despite its scarcity it was felt that an action statement, although not a full
action plan, was required for this habitat in Avon, due to its national importance. Related plans:
Coastal and Floodplain Grazing Marsh, Watercourse and Floodplain.
Objective 1: Ensure no loss and maintain and enhance the quality of purple moor-grass and rush pasture in Avon
Target: Aim for 80% purple moor-grass and rush pasture to be positively managed by 2010 Objective 2: Expand the area of purple moor-grass and rush pasture in Avon Action Time Implementors Continue to manage purple moor-grass and rush pasture in Clapton, Weston and Walton moors and Max and Yanal Bogs

Hedgerows action plan 5.4
48
5.4.1 Current status 5.4.1.1 Definition For the purpose of this action plan, hedgerows are defined as any linear boundary composed of
native trees and shrubs. This includes ancient hedgerows in existence before the Enclosure Acts
(passed mainly between 1720 and 1840 in Britain) which tend to be those that support the greatest
diversity of plants and animals. It also includes hedgerows with a recent origin, whether species-
rich, containing five or more native woody species on average in a 30 m length, or species-poor.
Related Avon Plans: Arable Farmland, Dormouse, Woodland and Coastal and Floodplain Grazing
Marsh.
5.4.1.2 Biological status Hedgerows are a primary habitat for many species of conservation concern in the UK. They are
especially important for invertebrates, birds, bats, dormice, reptiles and amphibians, such as great
crested newt and provide an essential refuge for a great many woodland and farmland plants.
Hedgerows may also act as wildlife corridors for many species, allowing dispersal and movement
between other habitats. The South West has one of the highest concentrations of hedgerows in
the UK and Avon has lost fewer hedges than many parts of Britain because it is largely pastoral. In
urban areas hedges can also have other important functions such as landscape screening and
decreasing pollution. In Avon, hedgerows are particularly important in North Somerset and the
Cotswolds for dispersal of and as foraging sites, for bats and dormice and are an integral part of
the landscape character.
5.4.2 Current threats Each is linked with the relevant objective or cross-cutting actions section numbers (shown in italics) • Lack of wildlife-friendly management including too frequent or badly timed cutting and use of

Woodland action plan 5.5
5.5.1 Current status 5.5.1.1 Definition This action plan is for all semi-natural woodland found in Avon, both recent (over 5 years old) and
ancient (having been continuously wooded since at least 1600). It encompasses the UK priority
habitats of wet woodland, upland mixed ashwoods and lowland beech and yew woodland. It also
includes lowland mixed deciduous woodland. These woodland types frequently occur in mosaic with
each other, as well as with other habitat types such as heath and species-rich grassland. Related
Avon plans: Wood Pasture and Parkland, Species-Rich Grassland, Watercourse and Floodplain.
Lowland mixed deciduous woodland is a very rich habitat for wildlife with great variety in the
species composition of the canopy, understorey and ground flora layers. Trees of particular interest
found in mixed deciduous woodland in Avon include the wild service-tree, Bristol whitebeam, Wilmott’s
whitebeam, the rare whitebeam, Sorbus eminems, large-leaved lime and small-leaved lime. The
nationally rare purple gromwell and notable plants including wood vetch, herb-paris, toothwort, broad-
leaved helleborine and bird’s-nest orchid are among the species that live in this type of woodland. The
understorey also provides important habitat for dormice and old hollow trees make important roost
sites for bats and homes for saproxylic invertebrates, fungi, lichens and birds. Lowland mixed
deciduous woodland forms the majority of woodland in Avon (see table 5.5.1 and map 5.5.1 for
estimated amount). Fine examples include the ancient woodlands of Lower Woods in South
Gloucestershire, Leigh Woods in Bristol and Weston Big Wood in North Somerset.
Upland mixed ashwoods occur on base-rich soils. Ash is typically a major species, although locally
oak, birch, elm, small-leaved lime and even hazel may be the most abundant species. Mixed
ashwoods are amongst the richest habitats for woodland wildlife, notable for a rich invertebrate fauna
and lichen flora, and flowers such as herb-paris, Goldilocks buttercup, purple gromwell, bluebell,
primrose and wild garlic. In Avon upland mixed ashwoods occur on the ridges around the Gordano
Valley and on the Mendips (see table 5.5.1 and map 5.5.1 for estimated amount)
Lowland beech and yew woodland spans a variety of distinctive vegetation types reflecting
differences in soil and topographical conditions. The association of beech with yew tends to be most
frequent on calcareous sites. Extraordinary sessile yews are found in Goblin Combe. Characteristic
uncommon or rare plants found in beech and yew woodland in Avon include bird`s-nest orchid. In
Avon examples of lowland beech and yew woodland can be found in the Avon Gorge and Goblin
Combe (see table 5.5.1 and map 5.5.1 for estimated amount).
Woodland action plan 5.5
Wet woodland occurs on a variety of poorly drained or seasonally wet soils, usually with alder, birch
and willows as the predominant tree species, but sometimes including ash, oak, pine and beech on the
drier riparian areas. Wet woodland is important for many taxa. The high humidity favours bryophyte
growth. The number of invertebrates associated with alder, birch and willows is very large. In Avon
there are important pockets of wet woodland on many sites including Leigh Woods, parts of the
Gordano Valley and in three SNCIs in South Gloucestershire: Roundhouse Wood, Tockington Park
Wood and Groves Gully (see table 5.5.1 and map 5.5.1 for estimated amount).
The amount of mapped habitat with known favourable management is also included in table 5.1.1 with
more details on www.avon-biodiversity.org.uk. Table 5.5.1: Number of hectares of lowland beech and yew, wet or mixed deciduous woodland and upland ashwood found in Avon compared with the estimated total national resource and the proportion of the resource held in SSSIs, AWT reserves, countryside stewardship agreements, LNRs and NNRs and so determined to have known favourable management. Number of hectares of each habitat falling into the four mapped habitat categories* in the NBN/SW pilot habitat mapping project are given (see section 4.6.2 for details).

5.5.1.3 Priority areas for action Priority areas for survey, maintenance, restoration and re-creation (see table 5.5.2) were identified by a
panel of experts on woodland in Avon and through consultation with Avon Biodiversity Partnership
members. Priority areas for habitat re-creation/management identified in the Rebuilding Biodiversity
project were taken into account. Habitats mapped in the NBN SW pilot project (July 2003) were taken
as the base line for the extent of woodland in Avon.
Table 5.5.2: Priority areas for action Priority areas for survey, maintenance and woodland creation were identified by a panel of experts on woodland in Avon and through consultation with Avon Biodiversity Partnership members. Action Priority area survey Mendip Fringes (see map 5.1.2) and Doddington. More refined information on target areas for survey

5.5.2 Current threats Each is linked with the relevant objectiveor cross-cutting actions section numbers (shown in italics)
Factors affecting all types of woodland include:
• Browsing by deer leading to changes in woodland structure, ground flora impoverishment and
difficulties for regeneration Objective 1 and section 4.5
• Grey squirrels which strip bark from many native trees, including ash, oak, beech, birch, wych elm
and field maple, leading to difficulties for regeneration and changes in woodland structure. This
may also influence the choice of species used for re-stocking Objective 1 and section 4.5
• Neglect and lack of favourable management for biodiversity Objectives 1,4
• Invasion by non-native species (including turkey oak and Japanese knotweed) reducing the
diversity of ground flora Objective 1 and section 4.5
• Dutch elm disease which has changed the structure and composition of many woods since the
early 1970s No actions for this as difficult to control
• Intensive management for game rearing (although when well managed this can be beneficial in
providing the woodland with an economic value – see threat below) Objective 1 and section 4.1
• Stock sheltering in woodland leading to the poaching of the ground, nutrient enrichment and some
direct damage to trees Objectives 1 and section 4.1
• Habitat fragmentation Objective 2 and section 4.7
• Local nutrient enrichment and herbicide drift leading to changes in soils and ground flora from
spray drift or runoff from adjacent agricultural land Objective 1 and section 4.1
• Development: directly, for example through urban growth and quarrying and indirectly, for example
through pollution, increased intensive unmanaged recreational use and trampling, and proximity of
housing to woodland edges Objectives 1, 4 and section 4.2
• Lack of perceived value of woodland as a resource for health and wellbeing but also due to
decreased demand for wood products Objective 4 and section 4.8
Factors affecting wet woodland alone include:
• Lowering of water-tables through drainage or water abstraction, resulting in change to drier
woodland types Objective 1 and section 4.3
• Flood prevention measures, river control and canalisation, leading to loss of dynamic disturbance-
succession systems and invertebrate communities, as well as possible reductions in the extent of
individual sites Objectives 1 and section 4.3
• Poor water quality leading to changes in ground flora composition and invertebrate communities

Wood pasture, parkland and veteran trees action plan 5.6
5.6 Wood pasture, parklandand veteran trees
Wood pasture, parkland and veteran trees action plan 5.6
5.6.1 Current status 5.6.1.1 Definition Lowland wood pastures and parkland are the products of historic land management systems, and
represent a vegetation structure rather than being a particular plant community. Typically this
structure consists of large, open-grown or high forest veteran trees (often pollards) at various
densities, in a matrix of grazed grassland, heathland and/or woodland floras. This plan includes:
• parks derived from medieval ‘forests’, some with 16th -19th century landscaping superimposed
• 19th century parkland with much older trees derived from earlier landscape
• 19th century parkland close to areas with very old trees and where conditions exist to ‘create’
veteran trees in 50-250 years
• under- or un–managed wood pasture with veteran trees
• parkland or wood pasture converted to other uses but with veterans surviving
This plan does not include parklands with 19th century or later origins with none of the above
characteristics. Related Avon plans: Species-Rich Grassland, Woodland.
5.6.1.2 Biological status The floral and faunal composition of lowland wood pasture and parkland varies depending on the
levels of grazing and canopy cover, and the habitat types present. While oak and beech are often
considered the typical trees of wood pasture and parkland, a wide range of other tree and shrub
species may occur as part of this habitat. Older and veteran trees along with decaying timber
support extremely rich assemblages of epiphytic lichens, fungi, mosses and ferns (particularly the
common polypody fern). They also provide habitats for many saproxylic invertebrates and some
bats and birds. In Avon, fine examples of wood pasture and/or parkland are found at Ashton Court
SSSI and in the deer park of the Badminton Estate.
5.6.1.3 Priority areas for action Wood pasture and parkland and veteran trees are a priority wherever it occurs in Avon, due to
their scarcity and diffuse distribution.
5.6.2 Current threats Each is linked with the relevant objective or cross-cutting actions section numbers (shown in

Standing open water action plan 5.7
5.7.1 Current status 5.7.1.1 Definition Standing open water in Avon includes: natural features such as oxbow lakes and ponds and
artificial features over 1 square metre in size, such as large water supply reservoirs, canals,
ornamental lakes, fish ponds, garden and farm ponds, dew and stock ponds such as those on the
Mendips, borrow pits and balancing ponds. Related plans: Watercourse and Floodplain, Reedbeds,
Coastal and Floodplain Grazing Marsh.
5.7.1.2 Biological status Standing open water in Avon is important for wintering and breeding birds, particularly wildfowl, and
as a migration stopover point for a variety of birds. The open water habitats at Chew Valley Lake
(SSSI and Natura 2000 site) support, particularly in the late summer and autumn, internationally
important numbers of shoveler and nationally important numbers of gadwall, coot, teal, tufted duck
and great-crested grebe. Both Chew Valley and Blagdon Lakes have large populations of water
plants. Many invertebrate and amphibian species rely on open water, for example ruddy darter and
great-crested newt. Areas of standing open water in Avon also support UK BAP mammals such as
water vole and otter. For example, the Kennet and Avon canal supports one of the few water vole
populations left in Avon.

Reedbeds and sedgebeds action plan 5.8
5.8.1 Current status 5.8.1.1 Definition This plan is for the UK BAP priority habitat of reedbeds but also includes actions for the locally
important sedgebed habitat. Reedbeds and sedgebeds are wetlands dominated by stands of
common reed, or lesser or greater pond-sedge wherein the water table is at or above ground level
for most of the year. Reedbeds tend to incorporate areas of open water and ditches, and small
areas of wet grassland and carr woodland may be associated with them. In some cases there may
be conflict between these and other priority habitat types, e.g. management for open water may
involve removal of reedbeds. Sedgebeds are found in moderately eutrophic substrates on the
margins of slow-moving or standing lowland waters in open water transitions, in wet hollows within
flood meadows, in ditches and alongside sluggish streams and rivers. Related Avon Plans:
Watercourse and Floodplain, Standing Open Water, Coastal and Floodplain Grazing Marsh.
5.8.1.2 Biological status Reedbeds are amongst the most important habitats for birds in the UK. In Avon they support
nationally rare red-listed bittern and provide roosting and feeding sites for migratory species. Rare
invertebrates associated with reedbeds in Avon include the horsefly Haematopota grandis (Red
Data Book 3) and the soldier beetle Silis ruficollis (nationally scarce). National BAP species
associated with both reedbed and sedgebed include water vole as well as bittern. Other important
species that find shelter in these habitats are water shrew, harvest mouse, reed warbler, sedge
warbler, southern marsh-orchid, early marsh-orchid, common spotted-orchid and yellow-sedge
sspp.
The most extensive area of reedbed in Avon (11 ha) is round Chew Valley Lake SPA. Blagdon
Lake holds patches of reedbed and smaller areas occur in Littleton Brick Pits, Lawrence Weston
Moor, Priory Farm, Blake’s Pools, and Midgell Pits. Reedbeds are often also found in Avon as
linear features in ditches. There are about 5000 ha of reedbed in the UK, but only 50 sites are over
20 ha. Sedgebeds are found in Avon in small quantities on Congresbury Moor, Lawrence Weston
Moor and Nailsea Moor.

Watercourse and floodplain action plan 5.9
5.9.1 Current status 5.9.1.1 Definition In response to concerns that current water policy is fragmented, a single piece of framework
legislation, the EC Water Framework Directive, has been developed. The new legislation will be
based on the management of river catchments and nearshore coastal water as natural
geographical and hydrological units, traversing administrative and /or political boundaries. The
Watercourse and Floodplain Action Plan therefore includes action for all linear watercourses
(channel and banks) from source to sea and for the whole floodplain. It was felt that coastal and
floodplain grazing marsh, whilst it is part of this system, warranted special attention due to its
particular value in Avon. Therefore a separate plan dealing with this habitat is included. The
estuary action plan is also very closely related to this one. Other related plans: Reedbeds and
Sedgebeds, Purple Moor-grass and Rush Pasture, and Woodland Action Plans. 5.9.1.2 Biological status Avon’s watercourses are a widespread and important resource, varying in character from the high
quality Frome to degraded urban watercourses (see map 5.9.1). They support a diverse range of
species. Many of these are nationally threatened, such as white-clawed crayfish and water vole.
Other important species include the dipper, a rich diversity of invertebrate species, and brown trout,
brook lamprey and salmon. One formerly nationally threatened species, the otter, is now returning
to much of its former range in Avon and is also returning to watercourses nationally.
5.9.1.3 Priority areas for action Table 5.9.1: Priority areas for action Priority areas for survey, maintenance and restoration were identified by a panel of experts on watercourses in Avon and through consultation with Avon Biodiversity Partnership members. Action Priority area

Coastal and floodplain grazing marsh action plan 5.10
2
5.10.1 Current status 5.10.1.1 Definition Coastal and floodplain grazing marsh is a landscape rather than a vegetation type. It is defined as
seasonally inundated permanent pasture or meadow within a level area with ditches which maintain the
water levels, containing standing fresh or brackish water. The ditches are especially rich in plants and
invertebrates and are a feature of key importance for biodiversity in the landscape. Almost all sites are
grazed and some are cut for hay or silage. The grassland can be improved or unimproved,
agriculturally speaking, and can be species-rich or species-poor. Sites may contain seasonal water-
filled hollows and permanent ponds with small areas of emergent swamp plant communities. Grazing
marsh usually occurs in river valley floodplains or behind coastal sea defences. Related Avon plans:
Estuary, Standing Open Water, Reedbeds and Sedgebeds, Species-Rich Grassland, Purple Moor-
grass and Rush Pasture.
5.10.1.2 Biological status The ditches in this landscape type are particularly valuable wildlife havens. In Avon, the flora and
fauna of ditches includes hairy dragonfly, great silver beetle, rootless duckweed and frogbit.
Floodplain grazing marshes are important for breeding waders such as snipe, lapwing and redshank
and for wintering birds such as jack snipe. Important mammal species associated with this habitat in
Avon include water voles. A fine example of floodplain grazing marsh in Avon is at Clapton Moor
where 18 ha of grassland standing in a network of species-rich ditches is periodically flooded. Other
examples may be found at Bathampton Oxbow, Weston Moor and the Gordano Valley NNR.
Historically, much of the North Somerset Levels and Moors and similar areas of landscape that extend
north into South Gloucestershire would have been floodplain grazing marsh.

Estuary action plan 5.11
5.11.1 Current status 5.11.1.1 Definition All of the coastal areas of Avon lie within the Severn Estuary. The estuary is one of the largest in
Britain and supports a range of distinctive communities intimately linked together by coastal
processes. A number have been identified as UK BAP priority habitats. In Avon these are
mudflats, maritime cliff and slopes, saltmarsh, coastal sand dunes, and Sabellaria reefs (see box
5.11.1 for definitions). The estuary is designated as a SPA under the EC Birds Directive. It is a
proposed (p)SAC under the EC Habitats Directive and has also been notified a Ramsar site (a
wetland of international importance). The first two designations relate to intertidal features such as
saltmarsh, mudflats and associated birds. The pSAC would relate to the whole estuary, including
the sub-tidal zone. It is also a SSSI. The estuary is defined as extending to the tidal limit of rivers.
This plan covers the whole of the SSSI and the tidal Avon beyond the SSSI designation.
The Severn Estuary as an ecological unit extends outside the boundaries of Avon and so cannot be
considered in isolation within the former county. This Habitat Action Plan aims to closely integrate
its objectives with those of other initiatives operating throughout the estuary, in particular the
objectives of the SSSI, SPA, pSAC (see below) and those of the Severn Estuary Strategy.
Related Avon Plans: Watercourses and Floodplain, Reedbeds and Sedgebeds, Coastal and
Floodplain Grazing Marsh.
5.11.1.2 Biological status
The Severn Estuary is an internationally important conservation area. Its funnel shape and
second-largest tidal range in the world create a unique, highly dynamic environment. Over 80
species of fish have been recorded in the Severn Estuary. These include several migratory
species such as salmon, sea trout, sea and river lampreys and in particular the UK priority species,
allis and twaite shad. The estuary supports internationally important wildfowl and wader
populations, in particular resident shelduck, winering dunlin, white-fronted goose, gadwall, and
redshank, and Bewick’s swan, and provides a key staging ground during migration for species such
as ringed plover and whimbrel.
The extensive intertidal mudflats found in Avon are home to species of worms, snails and
crustaceans, which provide food for the large numbers of migratory wildfowl, wading birds and
migratory fish. Saltmarsh is a significant and threatened habitat distributed all along the estuary’s
fringes in Avon (see map 5.11.1). Saltmarsh vegetation holds sediment from the Estuary, in some
cases maintaining a natural intertidal buffer for coastal protection and flood defence. The
saltmarshes support significant populations of nationally scarce plant species including slender
hare’s-ear, sea clover and bulbous foxtail, and are used for feeding by ducks and roosting by
Estuary action plan 5.11
waders. Maritime cliffs, such as those found at Steepholm, Middlehope, Battery Point, Aust and
between Clevedon and Portishead, contribute to the habitat diversity and provide roosting areas for
birds, including nesting peregrines. A number of sites along the estuary are of national importance
for their geology, including the Aust cliffs. There are several extensive Sabellaria reefs offshore
(see map 5.11.1), which provide habitat for a wide diversity of invertebrates. The Severn Bore is a
natural phenomenon of note, and the largest of its kind in Europe. The estuary is also well known
for the wealth of archaeological and historic interest features, as well as its high quality historic
landscape.
Map 5.11.1: Coastal saltmarshes and Sabellaria reefs
Estuary action plan 5.11
Mudflats are sedimentary intertidal habitats created by deposition in low energy coastal environments such as estuaries. They are intimately linked by physical processes to, and may be dependent on, other coastal habitats such as saltmarshes. Mudflats are characterised by high biological productivity and abundance of organisms, but low diversity with few rare species. The surface of the sediment is often apparently devoid of vegetation, although mats of benthic microalgae are common. The total UK estuarine resource has been estimated as c588000 ha. Coastal saltmarshes in the UK comprise the upper, vegetated portions of intertidal mudflats, lying approximately between mean high water neap tides and mean high water spring tides. For the purposes of this action plan, however, the lower limit of saltmarsh is defined as the lower limit of pioneer saltmarsh vegetation and the upper limit as one metre above the level of highest astronomical tides to take in transitional zones. The development of saltmarsh vegetation is dependent on the presence of intertidal mudflats. Saltmarsh vegetation consists of a limited number of halophytic (salt tolerant) species adapted to regular immersion by the tides. The estimated UK total saltmarsh resource is 45,500 ha (see map 5.11.1 for estimated amount in Avon). Maritime cliffs and slopes comprise sloping to vertical faces on the coastline where a break in slope is formed by slippage and/or coastal erosion. There appears to be no generally accepted definition of the minimum height or angle of slope which constitutes a cliff. The zone defined as cliff-top (also covered in this plan) should extend landward to at least the limit of maritime influence (i.e. limit of salt spray deposition), which in some exposed situations may continue for up to 500 m inland. This plan may therefore encompass entire islands or headlands, depending on their size. On the seaward side, the plan extends to the limit of the supralittoral zone and so includes the splash zone lichens and other species occupying this habitat. Approximately 4000 km of the UK coastline has been classified as cliff. Coastal sand dunes develop where there is an adequate supply of sand (sediment within the size range 0.2 to 2.0 mm) in the intertidal zone and where onshore winds are prevalent. The critical factor is the presence of a sufficiently large beach plain whose surface dries out between high tides. The dry sand is then blown landwards and deposited above high water mark, where it is trapped by specialised dune-building grasses which grow up through successive layers of deposited sand. There are estimated to be 11,897 ha of sand dune in England Sabellaria alveolata reefs are formed by the honeycomb worm S. alveolata, a polychaete which constructs tubes in tightly packed masses with a distinctive honeycomb-like appearance. Over time seaweeds and animals colonise so that older reefs may increase the biodiversity of what would otherwise be sand abraded rocks and boulders. In England, S. alveolata is only found on shores with strong to moderate wave action in the South and West (see map 5.11.1 for estimated amount). Sabellaria spinulosa reefs comprise dense subtidal aggregations of this small, tube-building polychaete worm. S. spinulosa can act to stabilise cobble, pebbles or gravel, providing a consolidated habitat for epibenthic species and many other associated species.

Note: Natural processes, such as sea level rise, erosion and accretion, have an enormous effect
on the estuary. It is a very dynamic system and in an unrestrained situation interconversion of
mudflats, sandflats and open water is expected. Increases in sea level and storminess due to
global warming are expected to affect these processes. The best we can hope to do is respond to
these changes in a way that is best for biodiversity.
A recent study by English Nature predicted a net accretion of sand over the next 50 years, which
may mean a natural increase in sand dunes. In general, the total area of mudflats is expected to
remain the same, although their position constantly moves. The only intertidal area that can
feasibly be created in the estuary within Avon is saltmarsh. With predicted sea level rise, however,
this may mean moving back over other habitat types, such as grazing marsh. Such conflicts of
interest between habitat types will have to be assessed and balanced on a case-by-case basis.
The objectives and actions of this plan are tailored in accordance with these facts.

5.11.3 Objectives, targets and actions to be read in conjunction with cross-cutting actions The work of the Association of Severn Estuary Relevant Authorities (ASERA), which seeks to ensure that relevant authorities fulfil their statutory obligations in respect to the nature conservation designations on the Estuary, will help to achieve some of the objectives in this plan Objective 1: Encourage the use of managed realignment as a viable and attractive option for coastal defence, to permit the creation of further areas of priority habitat in order to offset predicted losses to sea level rise Objective 2: Encourage management of the foreshore and surrounding hinterlands that is favourable to coastal wildlife and priority habitats Objective 3: Enhance the quality of the existing saltmarsh in terms of community and species diversity and, where necessary, restore the nature conservation interest through appropriate management Objective 4: Protect the existing sanddune resource and encourage accretion by active management
Action Time Implementors
Support the activities of the Severn Estuary Conservation Group, working towards a holistic view of the estuary
ongoing BCC, SGC, NSC AWT
Support the development of an estuary-wide coastal habitat management plan and defence management plans, which will feed into shoreline management plans, ensuring that they take account of available mechanisms for the management and creation of priority habitat and identify potential areas for managed realignment
ongoing Severn Estuary Coastal Group, DEFRA, EA, AWT
Support the establishment of the Severn Estuary European Marine Site Management Scheme and related projects
ongoing EN BCC, SGC, NSC, ASERA
Develop recommendations for positive work where realignment has occurred to progress the creation of priority habitats, publicising and disseminating them
ongoing EA EN, NSC
Encourage and/or implement appropriate management of priority habitats and look for opportunities to enhance, restore and create intertidal habitats
ongoing BCC, SGC, NSC, FWAG, ASERA, EA, EN, AWT, ASERA
Give due consideration to applications for dredging licences to ensure no adverse effects on biodiversity interest in the estuary
ongoing EA, BCC, NSC, SGC, DEFRA
Discourage mechanical beach cleaning close to dunes ongoing NSC, EN, EA Make use of the potential provided by existing estuary management partnerships in taking forward the actions in this plan
ongoing ASERA , SEP, AWT, NSC
Objective 5: Where possible ensure that new developments affecting the estuary, whether directly or indirectly, do not have an adverse impact on biodiversity interest. Where development is proposed, an Environmental Statement is likely to be required because of the environmental sensitivity of the area. In addition, plans and projects likely to have a significant effect on priority habitats within the Severn Estuary SPA and pSAC will require an appropriate assessment.
Action Time Implementors
Use the planning system and development control processes to prevent development in areas which could be used for coastal realignment or in areas at risk from flooding and coastal erosion or where development will have an adverse effect on priority habitats or exacerbate flood risk elsewhere and to protect and enhance existing resource
ongoing BCC, NSC, SGC, JSPTU, AWT
Where possible ensure that coastal defence or other construction works do not lead to a loss of, or damage to, estuarine priority habitats and where possible enhance them
ongoing BCC, NSC, SGC EN, EA, AWT
Objective 6: Improve estuarine water quality to ensure that existing priority habitats fulfil their important ecological and conservation role The water quality in the estuary should be improved through the application of a number of EU directives. Notable among these are the Dangerous Substances, Shellfish (waters), Bathing Waters, Integrated Pollution Control, Urban Waste Water Treatment and Water Framework Directives. The Oslo and Paris (OSPAR) Convention and North Sea Conference Declaration are also significant as these provide for the regulation of discharges to the sea and incorporate targets and quality standards covering a range of pesticides, metals and other toxic, persistent and bioaccumulative substances. The EA regulates discharges into the estuary.
Estuary action plan 5.11
Many industrial discharges contain organic compounds and heavy metals. Many fall under the Pollution Prevention Control (PPC) Regulations which require continued reductions in specific contaminants released.
Action Time Implementors
Maintain and where possible improve estuarine water quality (linked to discharge and dredging consents)
ongoing EA, BCC, NSC, SGC, DEFRA, WW
Investigate, monitor and take action on pollution events ongoing EA, NSC, SGC, BCC
Objective 7: Monitor condition and extent of priority habitats in the estuary Action Time Implementors Monitor status of birds in the estuary ongoing BTO (WeBS)
Objective 8: Increase awareness, understanding and appreciation of the estuary’s
biodiversity and its favourable management Action Time Implementors Raise awareness of the importance of and threats to estuary habitats ongoing ASERA, EMS
advisory group, AWT, EA, EN, NSC
Review, collate and publicise guidance material on estuary habitat management ongoing AWT, NSC, ASERA, EN, EA
Disseminate information about whereabouts of priority habitats and their sensitivities
ongoing AWT, EA, BRERC, SEP*, DEFRA, EN
*SEP has contract to have GIS-mapped habitats overlain with recreational activities. BRERC is a partner on the working group associated with this.
Terms: Sea and tidal defence: Defence to reduce the risk of flooding from the sea or tidal rivers Coastal protection: protection of the land from erosion and encroachment by the sea
In some cases it is not economical to maintain the existing line of defence and the defence is set back to a more sustainable location. This is often known as managed realignment, set-back or coastal realignment.
Dormouse Muscardinus avellanarius action plan 5a.1
5a.1.1 Current status Dormice live in a variety of different habitats, including hazel coppice but also many other types of
woodland with a thick understorey, hedgerows, and even in bramble scrub. Usually dormice will only
travel arboreally and therefore require blocks of habitat to be connected. In some cases, however,
they have been observed crossing up to 6-7m of open ground. Their habitat size varies with an
average of 300-400m2 in woodland and 500-800m in hedgerows. Dormice eat a wide range of food
including aphids, pollen, fruit and nuts, their diet changing throughout the year with the availability of
different foodstuffs. Dormouse populations are thought to have declined by around 50% in the last
100 years. The dormouse does not occur in Scotland or Northern Ireland and its core British
population is Southern England and Wales. Avon is roughly in the centre of this. Good populations
of dormice in Avon exist in the Cotswolds, Lower Woods (South Gloucestershire), the Broadfield
Down/Kings Wood complex and the Mendip Hills in North Somerset. Recent evidence suggests
there may also be good populations in the Gordano Valley and surrounding ridges. Dormice are
subject to strict legal protection under the Habitat Regulations meaning that a licence is needed for
any work handling them or as a last resort for developments that affect them.
5a.1.2 Current threats Each is linked with the relevant objective or cross-cutting actions section numbers (shown in italics)
• Habitat loss for example due to development or agriculture Objective 1 and section 4.2
• Habitat fragmentation, leaving isolated, non-viable populations Objective 2and section 4.7
• Changes in habitat structure due to poor management (e.g. understorey shading or decreased
species diversity in hedges/poor hedgerow management e.g. annual trimming) Objective 2
• Housing development, particularly associated with increased domestic cat numbers Section 4.2
• Lack of knowledge of whereabouts and value of dormice Objectives 3,4 and sections 4.6 and 4.8
5a.1.3 Objectives, targets and actions to be read in conjunction with cross-cutting actions Objective 1: Maintain dormouse populations in areas where they still occur Action Date Implementors Ensure dormice are a central consideration when assessing removal proposals for hedges, and that licences are applied for where appropriate
ongoing UAs, DEFRA, BRERC, AWT, EN
Objective 2: Enhance dormouse populations in areas where they still occur and encourage the spread of dormice through habitat creation to expand and link existing sites
