1 INTRODUCTION

1.1 Overview

1.1.1 Parsons Brinkerhoff (PB) has been commissioned by Cornwall Development Company to undertake an Arboriculture survey to inform the development and design of the proposed Newquay Aerohub development.

1.1.2 The scope of this report is to assess all qualifying trees, groups of trees, hedges and woodland (individuals with a stem diameter of at least 75mm when measured at 1.5m above ground level) within the site and those that adjoin the site who’s Root Protection Area (RPA) may be affected by the proposed development as defined in British Standard 5837 of 2012: Trees in relation to Design Demolition and Construction – Recommendations (BS5837).

1.2 Purpose of the Arboriculture Report

1.2.1 The purpose of the arboriculture report is to inform the site masterplanning process and to form part of the submission for outline planning permission.

1.3 Site Context

1.3.1 The site is approximately 35.5ha in size and predominantly comprises a mix of arable and pasture agricultural land separated by a number of Cornish Hedge banks, with linear wet woodland running east to west at the north of the site. The site is bounded by the existing Newquay Cornwall Airport to the north and east, by agricultural land to the west, and by the A3059 to the south.

1.3.2 Recent changes to the road layout and construction of an access road through the site have resulted in significant changes on site. Such changes include the removal of a section of woodland and some loss of hedgerow and landscape planting of native tree and hedgerow species at several locations within the survey area.

1.4 Planning and Legislative Context

1.4.1 The report has been carried out in accordance with the newly published (30th April 2012) BS 5837: 2012 “Trees in Relation to Design, Demolition and Construction – Recommendations”.

1.4.2 Trees are a material consideration in the UK planning system, and existing trees are an important factor on construction sites, whether on or near the working areas. BS 5837 2012: Arboriculture reports are intended to assist decision-making, by ensuring consideration is given to existing and proposed trees in the context of design, demolition and construction.

1.4.3 Root systems, stems and canopies, with allowance for future movement and growth, need to be taken into account in all projects, including those that do not require planning permission. The space required for any proposed new trees is an important consideration (extract of BS 5837: 2012).


2 METHODOLOGY

2.1 Field Survey

2.1.1 An arboricultural survey was undertaken by Parsons Brinckerhoff between 5th and 7thSeptember 2012. The trees on site were inspected and classified, by a competent arborist in accordance with BS5837: of 2012 “Trees in Relation to Design Demolition and Construction – Recommendations”. The trees were classified in accordance with BS5837: 2012 tree quality assessment categories A, B, C and U, as set out in Table 1 and 2 of the standard.

2.1.2 All trees whose root protection area could be affected by the proposed development were inspected from ground level using the Visual Tree Assessment (VTA) method. The VTA assessment is a non-invasive method for ascertaining the trees physiological and structural condition. The method requires the use of a Thor 10 nylon acoustic mallet, a wire probe and a diameter tape measure.

2.1.3 The VTA was undertaken on the above ground portion of the tree. It was carried out from ground level and no aerial inspection, sampling, or excavations for the purpose of soil or root analysis were undertaken. Binoculars were used to inspect the upper parts of the tree canopy from ground level, if required.

2.1.4 If dense vegetation prohibited access to the base of trees, an estimate of the trees measurements has been provided using accurate measurements taken elsewhere on site as a guide.

2.2 No vegetation was cut or moved without prior agreement of the land owner or tenant. Limitations of the Survey

2.2.1 Trees are large dynamic organisms, influenced by a variety of environmental variables, whose health and condition can change rapidly. Due to the changeable nature of trees and other site and environmental considerations which may influence the trees, this report, and any recommendations made within it are valid for a period of 12 months from the date of the site survey (September 2012).

2.2.2 Occasionally where trees were inaccessible due to physical barriers such as security fencing, or dense harmful vegetation such as Bramble and Thorn, it may not be possible to access to the base of the tree to carry out the required inspection. Where this is the case, all measurements have been estimated using adjacent trees as reference points. These measurements have been marked with EST (estimate) in the survey schedule.

2.2.3 Unless otherwise stated all stem measurements were measured at the time of the survey. All other measurements are estimates. The surveyor measured the height of several trees during the survey to ensure that all estimated were as accurate as possible.

2.2.4 All crown dimensions and height are to the nearest half metre and rounded up (in accordance with BS 5837: 2012) to afford a reasonable assessment of the trees characteristics.

2.2.5 Although comments and recommendations on the safety of particular trees may have been made, this survey is not a tree hazard assessment and should not be used as such.


2.2.6 All management recommendations have been made in accordance with BS 3998: 2010 “Tree Works – Recommendations” and industry best practice. Works have been recommended in accordance with any statutory obligations owed by the land owners or occupiers.

2.2.7 If any of the individual trees surveyed become a source of contention, at a later stage in the development of the Masterplan or submission of the outline application, it is recommended that a more detailed inspection of the tree is made and all estimated measurements confirmed as far as possible.


3 RESULTS

3.1 Overview

3.1.1 The site is dominated by arable and pasture fields separated by Cornish Hedge Banks. Although the hedge banks have been assessed in this survey as arboricultural features, it is understood that they are an integral part of the landscape and cultural history of the area. As such the true retention value and the implications of any removal of Cornish Hedge Bank should be appraised by using this report in partnership with the Habitat survey and Environmental Impact Assessment for the site. Wet Woodland identified at W1 and W2 to the North of the site is recognised as an important habitat type in the UK Biodiversity Action Plan (UKBAP). The UKBAP defined wet woodland and explained its importance as follows;

“Wet woodland occurs on 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. It is found on floodplains, as successional habitat on fens, mires and bogs, along streams and hill-side flushes, and in peaty hollows. These woodlands occur on a range of soil types including nutrient-rich mineral and acid, nutrient-poor organic ones. The boundaries with dryland woodland may be sharp or gradual and may (but not always) change with time through succession, depending on the hydrological conditions and the treatment of the wood and its surrounding land. Therefore wet woods frequently occur in mosaic with other woodland key habitat types (e.g. with upland mixed ash or oakwoods) and with open key habitats such as fens. Management of individual sites needs to consider both sets of requirements”.

“Wet woodland combines elements of many other ecosystems and as such is important for many taxa. The high humidity favours bryophyte growth. The number of invertebrates associated with alder, birch and willows, is very large, although some are now confined to just a few sites, for example the biodiversity priority species beetles Melanopion minimun and Rhynchaenus testaceus. Even quite small seepages may support craneflies such as Lipsothrix errans and the endemic Lipsothrix nervosa. Dead wood within the sites can be frequent, and its association with water provides specialised habitats not found in dry woodland types - the fly Lipsothrix nigristigma for example is associated with log jams in streams. Wet woodland provides cover and breeding sites for otters Lutra lutra. While few rare plant species depend on wet woodland per se, there may be relict species from the former open wetlands on the site such as the marsh fern Thelypteris palustris”.

3.1.2 With the above points in mind W1 and W2 as identified in the tree schedule have been awarded the highest retention category A 1/2/3 to reflect the high arboricultural, landscape, conservation and cultural value of the woodland.

3.1.3 A total of 2 Woodland areas (1 continuous woodland before the construction of the new road on site), 2 areas of new planting, 12 trees and 16 groups of trees were surveyed on the site and were allocated a quality category in accordance with BS 5837: 2012 (Appendix B), which indicates the extent to which they should be considered for retention based on their quality. All individual trees surveyed on site were tagged and labelled as T0333 to T0344 and the results of this assessment are presented in the Tree Schedule in Appendix A and on the Tree Constraints and Tree Protection plans in Appendix D and E respectively. New Planting 1 is identified as NP1 and shown at the southern edge of the site. NP2 is not shown on the plan but can be found 10m to the East of Tree 0344 at the North West corner of the site.


3.1.4 The individual trees on the site were allocated a quality category in accordance with BS 5837: 2012 (Appendix B), which indicates the extent to which they should be considered for retention based on their quality. The results of this assessment are presented in the Tree Schedule in Appendix A.

3.1.5 Individual trees were identified within the woodland edge of W1 and W2. This was to allow a reasonable Root Protection Area to be plotted for the woodland as a whole based on the stem diameter of the following trees: T0337, T0338, T0339, T0342, T0343 and T0344.

3.2 Ecology

3.2.1 Separate ecological surveys have been prepared for the Site; the habitats are reported in the Extended Phase 1 Habitats Survey (June 2012). However, it is important to be aware that trees contribute greatly to a wide range of habitat types for a multitude of protected species. The ecological survey reports should be considered in partnership with this Arboricultural report.


4 PRELIMINARY MANAGEMENT RECOMMENDATIONS AND CONCLUSIONS

4.1 Preliminary Management Recommendations

4.1.1 None of the trees recorded during the survey posed an imminent threat to persons or property or were found to require work to comply with legislation that relates to trees and vegetation.

4.2 Conclusion

4.2.1 The presence of significant trees or woodland on the site is not an obstruction to development. Careful consideration of trees at all stages of the development process will ensure that existing trees of high retention value are retained and protected throughout the development. Suitable mitigation for any tree loss will be designed into the scheme from the outset.

4.2.2 The Tree Constraints Plan (TCP), in Appendix D, will be used as tool to inform: the design of the site; the practicalities of implementing the development through the demolition of existing structures and any potential reclamation; the development and the final landscaping / mitigation planting.

4.2.3 When considering the national and local importance of Woodland 1 and 2 on the site, development should be avoided within the woodlands and their Root Protection Areas. Service runs should not be allowed to penetrate through the rooting areas of the woodland or to discharge into it.

4.2.2 Hedge loss is likely throughout the site as a result of the development, this should however be kept to a reasonable level and mitigated for (where possible) within the site and potentially on neighbouring sites should they be found to be suitable. When considering the areas of hedges to potentially be removed, this report should be read in conjunction with the ecological surveys to ascertain the areas that are likely to have the least impact.


5 ARBORICULTURAL METHOD STATEMENT (AMS)

5.1 Introduction

5.1.1 This method statement assumes that ecological, archaeological and any other relevant surveys such as Tree Preservation Order (TPO) and Conservation Area designations have been completed in the area and consent has been granted for the arboricultural works listed to commence.

5.1.2 Notwithstanding the details listed in the following method statement, no other development activity shall take place on site until the required protective fencing (as listed below) has been erected and confirmed to be appropriate by the Cornwall Council Arboriculture Officer or the Arboricultural consultant on site.

5.1.3 Protective fencing in accordance with section 7.3 of British Standard 5837 of 2012 “Trees in relation to design, demolition and construction – recommendations” shall be erected prior to any other work commencing on site (see Appendices C and E). If vegetation precludes the erection of such fencing it will be removed by hand and only with the expressed permission of the local planning authority.

5.1.4 Vehicular and pedestrian access to the site will only be via routes identified prior to the start of development activity and agreed as part of the planning application. Other means of vehicular access such as contractor’s car parking, materials delivery and turning aprons will be also be the subject of such controls.

5.1.5 Any pruning work required facilitating the development activity including the delivery of materials, erection of scaffolding or to achieve a satisfactory juxtaposition between the completed development and the retained trees / vegetation will be carried out only with the expressed permission of the local planning authority. All tree works will be carried out in accordance with British Standard 3998 of 2010 “Recommendations for tree works”

5.1.6 All materials arising from arboricultural works will be disposed of in a responsible manner and in accordance with the directions of the land owner and / or Cornwall Council.

5.1.7 Method statements detailing the construction type and method of any development within the root protection areas of trees identified for retention will only be carried out once the local planning authority has agreed those works will not be to the detriment of retained trees / vegetation.

5.1.8 The location of all development related materials activities and infrastructure such as welfare facilities, area for washings, spoil heaps and fuel stores will be confirmed at application stage. No potentially harmful liquids or washings will be allowed to drain towards protected areas.

5.1.9 Any demolition or removal of existing banked hedges, stone walls or other such structures, in proximity to trees identified for retention, will be carried out from within the footprint of proposed development. Where demolition by machine poses a threat to trees identified for retention, demolition by hand will be carried out as far as is practicably possible. In some cases it may be expedient to also install ground protection as identified in Figure 3 of BS 5837 of 2005.

5.1.10 Areas of mitigation or compensatory planting will be identified on site and protected as far as practicably possible to avoid compaction or degradation of the soil structure


by development activates. All loses in planting will be made good to 90% in the first 3 years after completion and to 75% up to the end of year 5. No further replacements will be made after this time. All planting operations are to be carried out in accordance with British Standard 4043 “Transplanting Root Balled Trees” and British Standard 3936-1 “Nursery Stock –Trees and Shrubs”, industry best practice should also be observed.

5.2 General Comments

� No development activity shall take place within the Root Protection Area (RPA) of retained trees.

� No fires shall be lit within 5m of the total canopy spread or RPA of retained trees.

� No washings, storage of materials or positioning of site equipment such as welfare facilities will be permitted within the RPA of retained trees.

� No service runs shall be permitted within the RPA of retained trees.

1. SUMMARY Spalding Associates (Environmental) Ltd. has been instructed to undertake an Extended Phase 1 Habitat Survey on land for the Aerohub Business Park to the south of Newquay Airport in Cornwall. This 35.5ha site consists of nine fields of varying size, five of which were being managed at the time of survey as productive agricultural grasslands for grazing and livestock fodder with the eastern most field planted with a vegetable crop. The new access road into the south of the airport has bisected the western most field such that it now consists of an eastern enclosure managed as agricultural grassland, and an open area to the west of the access road that is continuous with its western verge. The small field adjacent to the works compound in the south west of the site has developed a tussocky grassland through a lack of active management or grazing whilst the field to the east of the access road junction from the A3059 consisted of patchy grassland with frequent ephemeral weeds in areas disturbed during road construction. Along the northern site boundary is an area of damp woodland within the shallow valley bottom fringing two small streams, both of which rise within this site and flow from east to west. A low deteriorating bank with frequent mature trees is present within this woodland along the bottom of the valley. The majority of boundaries consisted of Cornish hedgebanks supporting a well managed, but low hedgerow of common native woody scrub. Occasional hedgebanks within the site supported a hedgerow of mature trees whilst. The only built structures within the site are a barn along the southern boundary of Field F3 and two walls and a concrete base that are the remnants of a partially demolished building in the south eastern corner of Field F1. Site designations - The site does not lie within or adjacent to a designated nature conservation site. Habitat features - The streams, wet woodland and the majority of hedgebanks throughout the site would qualify as Local and National BAP Priority Habitats. The loss of these habitats would be a material consideration in the determination of a planning application. There is some potential that individual hedgerows would qualify as Ecologically Important under the Hedgerow Regulations 1997. Should these hedgerows need to be removed they should be formally assessed by further survey. If they are found to qualify their removal would be a material consideration for the planning authority. Badgers - Badger are active within this site although sett location is unknown. Further surveys are recommended to locate and map any setts within this site so that an assessment can be made of how the proposed development will impact these features. Bats - It is likely that bats are foraging and commuting within this site and it is possible that bats are roosting within woodland, mature trees and the barn in the south of the site. Further surveys are recommended to determine the importance of this site and its features for bats. Common Dormouse - It is possible that Common Dormice are present within hedgerows at this site. Due to the potential for the proposed development to impact these habitats, it is recommended that further surveys be completed to ascertain the status of this site with regard to Common Dormice.


3

Nesting birds - There is little doubt that nesting birds will be present within this site during the nesting season. Further surveys should be completed to ascertain the importance of habitats within the proposed development site for breeding birds. Any activities that are likely to negatively impact potential bird nesting habitats (scrub, trees and hedges) should be completed in the period between September to February, outside the accepted bird nesting season. Reptiles - There is reasonable potential for reptiles to be present on the site, and particularly within marshy grassland, wet woodland and adjacent habitats, and along field boundaries. Any activities that are likely to injure or kill individuals should not begin until reasonable avoidance measures have been taken e.g. translocation. Further survey work should be completed to establish the presence or absence of reptiles so that reasonable and proportionate avoidance measures can be taken to ensure compliance with legislation. Reasonable efforts should be proportionate to the species and numbers of reptiles present. Maintaining and enhancing the biodiversity of the site - Further surveys to clarify the status of this site with regard to a number of important species are needed to inform decisions for maintaining biodiversity within the site. However, in a site of this size there is opportunity for both the maintenance and enhancement of the existing biodiversity associated with the major features of conservation value which are the mature trees, wet woodland, hedge boundaries and the shallow valley and streams.

2. INTRODUCTION

2.1 Background Spalding Associates (Environmental) Ltd. has been instructed to undertake an Extended Phase 1 Habitat Survey on land for the Aerohub Business Park to the south of Newquay Airport in Cornwall. The area surveyed was within the study area indicated on Map 1. 2.2. Survey aims

The purpose of this report is to:

• describe the habitats of the site using standard habitat classification methods • identify the nature conservation value of the habitats • locate, or identify signs of, protected or priority species • identify any issues that require further survey at suitable times of the year • make further recommendations.

2.3. Methods 2.3.1. Field methods A walk-over survey was undertaken on the 1st June 2012. Habitats were classified and mapped using the standard Phase 1 Habitat survey methodology (JNCC, 2003). The site was examined for species and habitats of nature conservation importance. A list of vascular plants found during the survey is included in Appendix 2. Vascular plant species were identified according to Stace, 1997. 2.3.2. Desktop methods Biological records of statutory and non-statutory nature conservation sites, UK Biodiversity Priority Habitats, UK Priority Species and species of conservation concern were searched for in an area extending 1km from the centre of the site by the Environmental Records Centre for Cornwall and the Isles of Scilly. In addition, records for Common Dormice and bats were searched for in an area extending 5km. The area of search is shown in Appendix 3 with a summary of the desk top search. The results of the search have been assessed for their relevance to the nature conservation interest of the proposed development site, and the key conclusions have been incorporated in this report. 2.4. Assessment

Habitats and species located during the field survey have been assessed for their nature conservation and biodiversity significance according to present standard criteria (listed in Appendix 1); the criteria consist of international, national and local designations and include statutory legislation and non-statutory designations 2.5. Constraints All areas of the site were readily accessible although at the time of the survey some species would not have been evident or identifiable due to seasonality and could have been overlooked.

2.6. The report and map The results of the field survey are provided in this report. The “study area” consists of the proposed site and its boundary (see Map 1). Fields have been coded F1 to F9 and hedges have been coded H1 to H25. These are identified on Map 1. Reference is also made to the landscape immediately surrounding the site where issues of nature conservation importance are deemed relevant. The habitats of the study area are described in detail and a map is provided showing the location of the habitats and key site features. The biodiversity of the site and the features of nature conservation importance are then assessed against standard criteria, the potential for impacts from the proposed plans (as provided) are identified and outline recommendations for mitigation and enhancement are provided.

3. SURVEY RESULTS

3.1. General description of the site This proposed development site to the south of Newquay Airport consists of an area of agricultural land and the adjoining narrow fringe of woodland along its northern boundary. Fields within the south and east of the site are relatively flat although those towards the northern western boundary slope gently into the shallow stream valley along which the fringing woodland has developed. To the south of the site is the busy A3059 road from Newquay and St Columb Major whilst to the east is the new Cornwall Air Ambulance site, to the west is agricultural land and to the north is Newquay Airport. 3.2. Description of habitats 3.2.1. Overview This 35.5ha site consists of nine fields of varying size. Five of the fields were being managed at the time of survey, to a greater or lesser degree, as productive agricultural grasslands for grazing and livestock fodder (F2 – F6) with the eastern field planted with a vegetable crop (F1). The new access road into the south of the airport has bisected the western field (F7) such that it now consists of an eastern enclosure managed as agricultural grassland, and an open area to the west of the access road that is continuous with its western verge. The small field adjacent to the works compound in the south west of the site (F8) has developed a tussocky grassland through a lack of active management or grazing whilst the field to the east of the access road junction from the A3059 (F9) consisted of patchy grassland with frequent ephemeral weeds in areas disturbed during road construction. Along the northern site boundary is an area of damp woodland within the shallow valley bottom fringing two small streams, both of which rise within this site and flow from east to west. The majority of boundaries consisted of Cornish hedgebanks supporting a well managed, but low hedgerow of common native woody scrub. Occasional hedgebanks within the site supported a hedgerow of mature trees. A low deteriorating bank with frequent mature trees is present within woodland and adjacent to the stream along the bottom of the shallow valley and marks the northern site boundary. Sections of new hedgebank have been created either side of the access road junction where it meets the A3059. The only built structures within the site are a barn along the southern boundary of Field F3 and two walls and a concrete base that are the remnants of a partially demolished building in the south eastern corner of Field F1. 3.2.2. Semi-natural broadleaved woodland Almost the entire northern site boundary consists of a margin of damp broadleaved woodland supporting a diverse community of ground flora. In the east of the site this woodland is at its wettest with small pools of standing water at the time of survey. The dominant tree species was Grey Willow Salix cinerea with occasional Common Ash Fraxinus excelsior and Hazel Corylus avellana (Image 1), and occasional standing dead wood.
