1. Background 1.1. Introduction
This document summarises the progress of the Lower North Sustainable Soils Conservation Action Planning (CAP) process to the 30th June 2016. The process commenced in March 2014 and the planning team (refer Appendix 4) has met four times to develop the conservation plan for the region. This report is the first iteration of the CAP. The aim of the Lower North Sustainable Soils Conservation Action Plan is to
“Protect Soil Health and Condition for Agricultural Production”
1.1.1. Conservation Action Planning (CAP) The planning process for the Lower North Sustainable Soils Project uses the Conservation Action Planning (CAP) framework developed by the US‐based conservation group The Nature Conservancy www.nature.org as its basis. This framework is widely used in the development of international conservation projects and is becoming more widely adopted in Australia for planning large scale conservation projects with multiple stakeholders. One of the underpinning goals of CAP planning is to move conservation projects from the paddock scale (10’s or 100’s of hectares) to the conservation and preservation of functional landscapes (100,000’s hectares) which are able to sustain biodiversity at an eco‐regional scale (Low, 2003). This CAP utilises the same principals of biodiversity conservation for soil conservation. The CAP process typically involves a series of conservation planning workshops with 5‐10 participants from multiple organisations. The process is facilitated by a trained CAP coach and uses a standard step‐by‐step methodology (refer Low, 2003) and an Excel‐based program, or Miradi software, to guide participants through the development of a 1st iteration landscape conservation plan. Whilst built on solid scientific principles, the approach recognises that there are often large gaps in knowledge and data sets and hence a strong on‐going adaptive management ethic is implied throughout the process. It also recognises that a large amount of knowledge exists with local practitioners and therefore incorporates local practitioner input into the planning process. The major steps in the CAP process, as outlined in this document, are:
an analysis of the regional context in which conservation is to occur;
the identification of conservation assets and nested assets (i.e. land uses, crop types, highly productive areas);
an analysis of the viability (i.e. health) of the conservation assets and the key threats;
the development of measurable objectives to achieve the long‐term conservation of the assets;
the development of conservation strategies, action steps and key programs to achieve the conservation objectives;
the development of a practical monitoring and evaluation program and adaptive management framework.

1.2 Regional Context
1.2.1 Northern and Yorke Natural Resources Management (NRM) Board Region The NRM region extends from the northern Adelaide plains in the south to the Southern Flinders Ranges in the north, and includes the whole of the Yorke Peninsula. In total the Northern and Yorke NRM region covers over 3 million hectares and supports a population of approximately 95,000 people (Northern and Yorke NRM Board, 2009). The Northern and Yorke NRM Board region has been split into three Sustainable Soil CAP regions based primarily on soil types, rainfall and land uses (see map 1). These three sub‐regions are:
Lower North Region
Upper North Region
Yorke Peninsula Region 1.2.2 Soil Management Organisations, Programs and Legislation The CAP process is a planning process which complements existing plans and strategies (refer Appendix 1 for Northern and Yorke NRM regional goals). The principle organisations involved in soil management in the region are Natural Resources Northern and Yorke, the State Government Department of Environment, Water and Natural Resources, Rural Solutions South Australia and Primary Industries and Regions South Australia (PIRSA). The former two organisations underwent a merger in 2010/2011 and now function primarily as one organisation. Rural Solutions is effectively the commercial arm of PIRSA. The Grains Research and Development Corporation (GRDC) and the Commonwealth Scientific and Industrial Research Organisation (CSIRO) are responsible for advancing research and adoption of practices which improve production. Local landholders, farmers and pastoralists are also supported by organisations such as Ag Excellence Alliance and local grower groups to improve the sustainability and profitability of farming practices.

1.3 Lower North Sustainable Soils Project Area
The Lower North Sustainable Soil project area covers approximately 1.2 million hectares of undulating, inland terrain. The region is generally regarded as being prime agricultural country supporting a broad range of primary production enterprises as well as several regional population and administration centres (refer Map 2). 1.3.1 Climate and Rainfall The project area is subject to a typical Mediterranean climate with mild wet winters and hot dry summers. The average annual rainfall is greatest in the western parts of the region corresponding to the significant relief of the range in this area (refer Map 2). The region is prone to periodic droughts which have occurred with relative regularity since records began (Schwertfeger & Curran in Davies et al, 1996). Not entirely coincidentally, Goyder’s Line, historically regarded as marking the point at which cropping is not viable, closely aligns with the regional boundary. Average annual rainfall is between 300mm on the eastern plains near Eudunda, up to 600mm in the ranges about Clare. Chart 1: Median Monthly Rainfall
(Bureau of Meteorology, Climate Data Online, 2014) 1.3.2 Regional Landforms The project area is characterised by a series of roughly north‐south oriented ranges. Some ranges are steep and sharply ridged whilst others are lower, forming rolling hills. This range‐valley landscape significantly influences soil characteristics and therefore land use; generally cropping is practiced on the deeper soils of the valleys and grazing practiced on the shallow‐soiled ranges. Most of the NYNRM region’s major watercourses at least partially run through and originate in this CAP region including the Burra Creek, Hutt River, Wakefield River, Broughton River, Rocky River, Light River, Willochra Creek and the Gilbert River.

1. Background
1.3.3 Soil Types The following analysis is based on the Soils of SA report and associated distribution mapping by PIRSA (2002) and DWLBC (2005). Large parts of the region, namely the northern most (around Hawker) and western most (Port Augusta and the Eyre Peninsula) are not captured in this mapping dataset. Statistics below relate to the mapped areas only. Refer to Map 3 for soil type distribution. The most common soil type in the project region is ‘Hard red‐brown texture contrast soils with alkaline subsoil’ which makes up around 49% of the area and is found throughout the region, predominantly on the plains and low hills. These soils are firm to hard loamy sands to clay loam surface soils over red or brown sandy clay loam to clay subsoils. Topsoils are usually in the 10‐40cm range. Topsoil waterlogging is common early in the season, but thee soils dry out rapidly and tend to seal over and set hard and this can result in patchy crop establishment. Inherent fertility is moderate to high, depending on clay and organic matter content. Leaching losses of nutrients are low in these soils and problems of mineral fixation and deficiencies are minimal. Phosphorus and Nitrogen are widely deficient however fertility levels are relatively easy to maintain. The next most common soil type is ‘Calcareous soils’ which makes up around 30% of the area and are predominantly found on the plains and low hills in the northern parts of the region. They are well drained, except when overlying clayey subsoils, and can be excessive in deep soils with light textured subsoils. Hard carbonate fragments on the land surface hinder tillage, seeding and harvesting of some crops and often stone picking or rolling are required. Soil pH is alkaline in the surface and alkaline to strongly alkaline in the subsoil. Surface soils often have high organic matter contents because biological activity and the corresponding rate of decomposition is reduced in calcareous soils. Inherent fertility varies with nutrient retention capacities, which are directly related to soil texture and organic matter levels. Phosphorus, Nitrogen and Zinc are widely deficient. Although Phosphorus is not leached in these soils, it suffers from reduced availability and applications of phosphorus fertiliser are needed to maintain productivity. Legumes and Nitrogen fertiliser are used to maintain Nitrogen at productive levels. The next most common soil type is ‘shallow soil on rock’, covering approximately 13% of the area. These soils are predominantly found on and near the ranges. They are generally unsuitable for cropping. Chart 2: Extent of various soil types in the Lower North CAP region
1.3.4 Land Use
The most common land use by area in the region is cropping (55% of area). The next most common land use is grazing which covers 32% of the land. This is probably an under estimate as much of the Southern Flinders Ranges are mapped as “other minimal land use” which is probably grazing on remnant vegetation. Other significant land uses include transport and communication (2%) and nature conservation (1.9%). Irrigated perennial horticulture, such as vines, covers 0.7% of the region.

Other significant regional centres include Jamestown (1,400), Crystal Brook (1,300), Burra (900), Eudunda (600) and Orroroo (540). Total population is difficult to assess as the CAP boundary does not correspond to statistical boundaries (see Map 5), however an approximation using Local Government Areas gives a figure of approximately 23,200 people (refer to Table 4 below).

2. Identification of Conservation Assets
2.1. Methodology for Identifying Conservation Assets The first step in this conservation action planning process involves the identification of a small number of focal conservation assets (i.e. soil types, climatic regions, land uses) that collectively represent the soils of a region. The explicit assumption within this process is that by protecting these examples of broad‐scale soil types the majority of land uses and productivity will also be conserved. The list of focal conservation assets therefore need not be long and exhaustive; rather, it should be short and representative. In general, the CAP methodology recommends that no more than eight conservation assets are selected to be the focus of a landscape conservation program. The asset selection process begins by identifying the coarse‐scale soil types and land uses for conservation. The issue of whether to lump individual soil types together or split into individual conservation assets is often a difficult one. In general, soil types are lumped together if they: ● co‐occur across the landscape; ● share similar land management practices; ● share similar threats. Source: Adapted from Low (2003)
2.2. Soil Conservation Assets of the Northern and Yorke Region
Five key conservation assets have been identified by the Lower North Sustainable Soil planning team. Each conservation asset is associated with numerous nested assets (i.e. soil types and land uses) which are an important focus of conservation efforts and help further define the asset. The five conservation assets are
1. High Rainfall (>400mm) Plains and Valley Floors 2. Medium Rainfall (<400mm) Plains and Valley Floors 3. High Rainfall Mid Slopes 4. Medium Rainfall Mid Slopes 5. Non‐arable Ranges
Assets were determined based on landscape position and rainfall as these are the primary drivers of land use and exacerbating factors behind threatening processes. Plains and Valley Floors are generally deep, fertile soils which are used for broad acre cropping. Mid slopes’ soils generally shallower than the Plains and Valley Floors however they still support extensive broad acre cropping. These two broad categories of landscape position were split between greater than or less than 400mm average annual rainfall. Non‐arable Ranges are generally very shallow soils, usually with significant rock outcropping, which are therefore not suitable for cropping and are primarily utilised for grazing. As the amount of rainfall these ranges receive is not a driver of land use it was not seen as necessary to split the asset by rainfall.
The spatial distribution of the assets are presented in Map 6. This mapping is derived from the DEWNR SA Soils spatial layer by re‐attributing the “Type_TXT” field.

3. Viability of Conservation Assets
3.1. Methodology for Assessing the Viability of Conservation Assets The second step in the conservation action planning process is an assessment of the viability (or overall health) of the conservation assets. This is a four step process. Step 1 Identification of a small number (3 – 5) of key attributes for each conservation asset. Key attributes represent the critical factors required for the long term viability of the conservation assets. These factors relate to the size, condition and landscape context of the assets and include attributes such as soil health, productivity and soil cover (refer Table 4). Step 2 Identification of appropriate monitoring indicators for each key attribute. Monitoring indicators are easily measurable factors closely related to the status of the key attributes. For example, the amount of standing vegetation soil cover may be an appropriate monitoring indicator for soil stability. Step 3 Development of criteria for rating the current status of each indicator. The development of criteria for rating the status of each indicator is an iterative process that typically starts as a simplified qualitative assessment (e.g. lots, some, few) and is progressively developed into more refined, numeric value ranges (e.g. 100% cover for 95% of the total area). Step 4 Ranking the current status of each indicator to determine the overall viability of the conservation assets. The final step in assessing the viability of the conservation assets is to rank the current status of each indicator based on the criteria for poor, fair, good and very good (described below). These individual ratings are rolled up in the Conservation Action Planning software to provide an assessment of the overall viability for each asset (refer table 4). POOR – allowing the factor to remain in this condition for an extended period of time will make restoration or preventing extirpation practically impossible. FAIR – the factor is outside its range of acceptable variation and requires human intervention. If unchecked, the target will be vulnerable to serious degradation. GOOD – the factor is functioning within its range of acceptable variation; it may require some human intervention. VERY GOOD – the factor is functioning at an ecologically desirable status, and requires little human intervention. Source: adapted from Low (2003)
3.2. Viability of the Conservation Assets of the of the Northern and Yorke Region
The overall viability of the conservation assets, as assessed by the planning team, is displayed in Table 5. Viability was determined by identifying and rating the current status of the key attributes of each conservation asset based on considerations of size, condition and landscape context (refer Table 5). These assessments were supported by existing monitoring data and reports for some key attributes and in other cases were based on local expert opinion. The absence of quantitative data for assessing the viability of some key attributes highlights a gap in the existing monitoring programs and an area for future development (refer section 7).

Table 6 shows that the region overall has ‘good’ viability, however both Mid Slopes assets have ‘fair’ viability. The assessment of the Key Attributes highlights the issues in the region being linked to erosion (i.e. soil stability and soil depth indicators) and acidity (soil fertility – pH indicator). Soil Biota were recognised as being a key component of healthy soils, but it was felt there was not enough knowledge present in the group, or possibly the industry, the accurately determine a suitable indicator let alone assign a ranking to the state of this Key Attribute. It has been kept in the CAP to highlight the knowledge gap.

4. Threats to Conservation Assets 4.1. Methodology for Assessing Threats The third step in the conservation action planning process involves the identification of high priority threats to the conservation assets. This is a two‐step process. The first step involves an assessment of the severity of the key stresses to the conservation assets. Stresses are inversely related to the key attributes (refer section 3) and may include altered rainfall patterns, increased pollutants, reduced productivity, reduced water infiltration, etc. Stresses are ranked from very high to low based on: ● severity of damage where it occurs i.e. what level of damage can reasonably be expected within 10 years under current circumstances (Very High – destroys or eliminates the conservation asset, High – seriously degrades, Medium – moderately degrades, Low – slightly impairs); ● scope of the damage i.e. what is the geographic scope of impact on the conservation asset that can be reasonably expected within 10 years under current circumstances (Very High – very widespread, High – widespread, Medium – localised, Low – very localised). The second step in the process involves the identification and ranking of the source of stresses (i.e. the direct threats). For example, the source of stress for increased standing water level may be vegetation clearance or the source of stress for reduced productivity may be introduced pests. Sources of stress are ranked from very high to low based on: ● contribution of the source to the stress i.e. expected contribution of the source, acting alone, to the full expression of the stress under current circumstances (i.e. Very High – very large contributor, High – large contributor, Medium – moderate contributor, Low – small contributor). ● irreversibility of the stress caused by the source (Very High – not reversible, High – reversible, but not practically affordable, Medium – reversible with reasonable commitment of resources, Low – easily reversible at low cost). Once the stresses and sources are ranked according to the above criteria, a summary rating for each threat is generated by the Conservation Action Planning (CAP) software. This results in the threats summary table (refer Table 6) that allocates a ranking for each threat from very high to low, both in terms of the threat to the individual conservation assets and to the collective impact of the threat across the landscape. Source: adapted from (Low, 2003)
4.2. Threats to the Conservation Assets
The key threats to the conservation assets are displayed in Table 7. As identified in the Viability Assessment above (Section 3) many threats impact on erosion. The wording of the threats captures the stress‐source interaction to better conceptually manage the contribution of each source to the stress. This has been captured diagrammatically using Miradi to develop a Situation Analysis (see Diagram 1 below).

5. Setting Conservation Objectives
5.1. Methodology for Setting Conservation Objectives The fourth step in the conservation action planning process involves setting measurable objectives that, if achieved, would ensure the long term conservation of the assets. In particular, objectives are developed in line with the S.M.A.R.T principles (i.e. specific, measurable, attainable, realistic and time‐bound) and are aimed at addressing high priority threats or achieving improvements in size, condition and landscape context attributes.
5.2. Conservation Objectives Objective 1: By 2020 the number of days that erosion prone cropping soils is protected (score 1‐5) from erosion is increased to 340 days of the year. Objective 2: By 2020 the number of days that erosion prone grazing soils is protected (score 1‐5) from erosion is increased to 340 days. Objective 3: By 2025 methods to increase resilience to extreme weather are investigated and findings are implemented. Objective 4: By 2025 restore pH to, and maintain above 5.5 across xx% of at risk land. Objective 5: By 2020, adequate surface cover is maintained in 80% of hilly un‐arable land (Non‐arable asset) to reduce erosion risk while managing fuel loads. Objective 6: By 2025 the infiltration rate of the of top 10cm of soil in priority areas is improved to reduce the incidence of water erosion.

6. Conservation Strategies, Action Steps and Key Programs
6.1. Methodology for Developing and Prioritising Conservation Strategies
The fifth step in the conservation action planning process involves the identification of effective strategies and action steps to achieve the conservation objectives developed in Section 5. This is a three step process. Step 1 Conduct a thorough situation analysis of the key factors related to the conservation objectives. This includes consideration of the causal factors underlying particular threats and potential hurdles for enhancing the condition of conservation assets (e.g. social, cultural, economic and individual motivations). This can help pinpoint opportunities for intervention and guide decisions about which delivery mechanisms are best employed to achieve the conservation objectives (e.g. direct landholder targeting, use of volunteers or contractors, market based instruments, education programs, or legislative and policy changes). Step 2 Brainstorm conservation strategies and action steps. Conservation strategies and action steps are the broad courses of action required to achieve the conservation objectives. There are essentially three “pathways” for strategy development that should be considered for threat abatement objectives. These include: ● direct protec on or management of land or water; ● influencing a key decision maker; ● addressing a key underlying factor. Once the major strategies are identified, they may be broken down into smaller, more detailed action steps. Step 3 Prioritise conservation strategies and action steps according to a cost‐benefit and feasibility analysis. Useful considerations for prioritising strategies and action steps include the relative value of the asset (e.g. highly productive area), its level of threat, the contribution of the strategy to meeting the conservation objective, the duration of the benefit achieved and the potential leverage of the action (e.g. high profile site that provides a catalyst for further action). Feasibility of implementation should also be considered including the total cost and time required to implement the strategy, the ease of land access and the degree to which a lead individual / institution exists to implement the strategy. It may be useful to initially prioritise a small number of conservation strategies that provide a mix of high benefit and high feasibility (i.e. low hanging fruit) actions. In particular the high feasibility actions ensures that projects can get some early ‘runs on the board’ to leverage investment into the more complex and costly strategies. The use of specialised prioritisation tools such as the Investment Framework for Environmental Resources – INFFER (http://www.inffer.org/) can aid this process. Use of Conceptual Models Conceptual models are increasingly being used for strategy development in conservation planning. A conceptual model is a visual method (diagram) of representing a set of causal relationships between factors that are believed to impact on one or more of the conservation assets. A good model should explicitly link the conservation assets to the direct threats impacting them, the factors (i.e. indirect threats) influencing the direct threats, and the strategic activities proposed to mitigate those factors (WWF 2005). The Miradi software program (www.miradi.org) can be used to develop conceptual models and fully supports the Conservation Action Planning (CAP) process. It is recommended that conservation projects that have applied the CAP process investigate the use of the Miradi software and conceptual models during the strategy development stage.

Lower North Sustainable Soil Conservation Action Planning Summary 2016 34
7. Monitoring, Evaluation and Adaptive Management
7.1. Methodology for Developing a Monitoring Program The final step in the conservation action planning process is an ongoing one which involves the development and implementation of a rigorous monitoring, evaluation and adaptive management program. This serves a number of important functions including: ● determining whether the strategies and actions are achieving the conservation objectives; ● showing trends in the condi on of conserva on assets and the levels of threat; ● demonstra ng the effectiveness and efficiency of investment into the conservation program; ● linking local conservation outcomes with other programs to describe the local‐global biodiversity outlook In particular two types of monitoring and evaluation are identified in the conservation action planning process: 1) strategy effectiveness monitoring, and 2) resource condition monitoring (i.e. asset condition and / or level of threat). Appropriate Level of Resourcing for Monitoring and Evaluation Many researchers and conservation practitioners agree that a monitoring effort of 10‐20% of the total program budget is an appropriate level of resourcing. However the level of resources allocated to monitoring should vary in proportion to the level of certainty surrounding an assumption that action A will lead to outcome B. Higher levels of uncertainty may necessitate greater monitoring effort (i.e. replicated experiments and trials) to test a particular conservation theory. Use of Results chains Results chains are a relatively recent tool to assist conservation planners test assumptions that an action will achieve a desired objective. Results chains are broadly based on principles of logical framework analysis (developed in the 1960’s) and are supported by Miradi software (www.miradi.org ). By identifying interim results or milestones along a trajectory towards the delivery of an outcome, results chains make implicit assumptions about the expected results of activities explicit. This process typically results in more rigorous strategy development by the project team. Once a sequence of outputs and outcomes are represented as a results chain diagram, it is relatively easy to visualise and identify monitoring indicators and milestones along the way to a conservation goal.
7.2. Monitoring Indicators An effective monitoring program for the region should achieve two major outcomes: 1) RESOURCE CONDITION MONITORING ● provide quantitative data to confirm or revise the current status of the key attributes and overall viability of the conservation assets & / or the current status of the key threats; ● establish baseline data to monitor future changes in the status of the key attributes and overall viability of the conservation assets &/ or status of the key threats; 2) STRATEGY EFFECTIVENESS MONITORING ● provide quantitative data to assess the effectiveness of the conservation strategies and action steps and identify areas for refinement. Monitoring indicators should be closely associated to the status of the key attributes and address landscape context, condition and size attributes of the conservation assets. A monitoring program should also make use of any existing monitoring data to ensure resources are used efficiently. This may involve creating links with other organisations that have complimentary aims or legislative requirements to undertake monitoring. It is acknowledged that the current indicators are not fully fleshed out. It will be a necessary action for this CAP group to more fully outline the Monitoring Plan in upcoming workshops.
