Summary

Native vegetation is an important and valued resource in the Adelaide and Mount Lofty Ranges (AMLR) NRM region because it provides habitat for native animals, places for recreation, and is culturally important for Aboriginal and non-Aboriginal people.

DEWNR staff from NR AMLR approached the Science, Monitoring and Knowledge (SMK) branch to assist in the development of a monitoring framework for native vegetation condition across the AMLR NRM region, the aim of which is to report on the state and trend of native vegetation condition across the region. The AMLR community is the target audience for these reports, including reporting against NRM plan targets.

A workshop was held in July 2015, and attended by staff from AMLR and other NRM regions,, , technical experts from DEWNR and the Nature Conservation Society of South Australia. The workshop aimed to inform the development of a monitoring framework for native vegetation condition. This document summarises the outcomes of the workshop, including:

- Outlining a framework for a monitoring plan and an implementation process - Identification and prioritisation of vegetation groups for monitoring.

- The values of native vegetation for conservation, production and other reasons.

- The expected management outcomes for each vegetation group.

- Identification of pressures for each vegetation group.

- Potential indicators of vegetation condition.

The outcomes of the workshop will be used to develop and trial the monitoring framework. The framework will be trialled in the first year, and will be refined for monitoring in subsequent years.

1 Workshop outcomes

1.1 Background

DEWNR Staff from the Natural Resources Adelaide and Mount Lofty Ranges (AMLR) NRM region are working to improve the information that is available to report on the condition of native vegetation at the NRM regional scale. The target audience for the improved information on vegetation condition is the AMLR community. Information on vegetation condition will be reported to the community by the AMLR NRM board using report cards as well as other reports, including those required to report against targets in the regional NRM plan. Regional staff indicated that reporting to the community at sub-regional or regional scales is required because many native vegetation management programs in AMLR are funded by the NRM levy.

A workshop was used to bring technical experts together to inform the development of a framework to monitor vegetation condition across the AMLR NRM region. Workshop participants proposed a number of guiding principles for the framework, including that it should:

 aim to inform region-wide reporting to the community, but that an increasing number of management questions may be incorporated if the monitoring program is improved;

 not aim to evaluate the effectiveness of specific management actions, which were implemented within projects, at site or landscape scales. Indicators for these purposes could be incorporated into the framework when resources are available;

 be practical and achievable within the available budget;

 have practical reporting outcomes, which relate to the values underlying each vegetation group;

 incorporate the results of project specific monitoring programs where ever possible, and implement monitoring methods in addition to those implemented by existing monitoring programs, where this is not possible;

 be adaptable so that new and improved methods could be incorporated in the future.

A project plan was developed before the workshop, outlining the aims, deliverables, budget, timeframes and governance of the project. The schedule of the project plan reflected the first 2.5 years of the project, but the workshop aimed to provide

direction for a long term (5 year) monitoring program. The workshop participants noted the alignment of the project plan with work being done for a separate project, which is modelling trends in the extent of native vegetation in South Australia.

1.2 Workshop overview

The workshop was held on 22 July 2015 in Adelaide at the Plant Biodiversity Centre, Botanic Gardens, between 9 am and 5 pm.

Participants included technical experts from DEWNR and NCSSA, Natural Resources AMLR and other NRM regions, as follows:

Keith Smith, Kristian Peters, Andrew West, Randall Johnson, Jason Van Weenen and Damian Moroney (AMLR NRM region), Michelle Waycott, Glen Scholz, Daniel Rogers and Nigel Willoughby (DEWNR SMK branch), Tim Bond (SE NRM region), Jackie Watts (SAAL NRM region), Jody Gates, Mark Storry and Valerie Lawley (DEWNR C&LM branch), Adam Wood (AW NRM region), David McKenna and Kirstin Abley (DEWNR P&S), Renata Rix (SAMDB NRM region), Andrew Triggs (KI NRM region), Lee Heard (NY NRM region), and Jeff Foulkes and Peter Mahoney (Nature Conservation Society SA).

The workshop was facilitated by Annelise Wiebkin and notes were recorded by Jane McKenzie and Craig Meakin (DEWNR SMK branch).

3 The goals of the workshop were to identify:

 existing programs, data and management outcomes on vegetation in AMLR.

 priority vegetation groups in AMLR for monitoring, and a plan to monitor each group every 5 years. Note

‘vegetation groups’ refers to a range of fine and broad scale vegetation associations and landscapes that are valued for a range of social, ecological and economic purposes.

 the important pressures, including ecological, social and economic, on priority vegetation groups.

 indicators of vegetation condition for the priority vegetation groups.

 site selection rules, and the timing of monitoring.

1.3 Existing data

The information on vegetation condition that was reviewed before the workshop included:

 summaries of existing vegetation management programs, including data and expected management outcomes for vegetation in AMLR.

 data on native vegetation condition in the AMLR NRM region, including Bushland Condition Monitoring (BCM) data (e.g. woodland birds, coastal vegetation) provided by the Nature Conservation Society of South Australia.

In addition to reviewing the above information, AMLR provided copies of other data on native vegetation condition. The data were reviewed so that they could be considered in the planning stages of the framework, for example to find areas where there were data gaps. At the workshop, the existing programs, data and management outcomes on vegetation in AMLR were summarised and presented to the participants. The workshop participants identified the following data, which will be assessed in detail before sampling sites are finalised:

 BCM, held by NCSSA, including coastal vegetation sites.

 BCM data, held by Greening Australia.

 Vegetation condition data in the form of polygons, held by A. West (AMLR).

 Data from the Biological Surveys, held by DEWNR,

 Data from TERN Ausplots.

 Vegetation condition data on the condition of the Fleurieu swamps, held by the NCSSA.

 Data from surveys of fire-responses of grey box grassy woodland and stringybark communities, held by DEWNR.

 Data from surveys of threatened ecological communities, held by Commonwealth Department for the Environment.

Workshop participants indicated that these data may not be spread representatively across each vegetation group in the AMLR NRM region. It was noted at the workshop that the current project would be expected to fill those gaps.

1.4 Prioritising vegetation communities

Participants were asked to come to the workshop with a list of 5 high priority vegetation groups in the AMLR NRM region, and a list of management questions that were relevant to the high priority vegetation groups. Five groups were chosen to ensure that workshop participants considered the high priority vegetation groups before the workshop, and to provide a meaningful number of groups to start discussions. The synthesised list of vegetation groups included terrestrial, coastal and freshwater aquatic systems, but intentionally excluded marine systems, including seagrass.

(9)

4 The proposed vegetation groups for region-wide reporting to the community were as follows:

Allocasurina woodland/forest (Allocasurina verticillata).

 Smooth-barked gum woodlands (Eucalyptus leucoxylon, E. fasciculosa, E. camaldulensis).

 Box gum woodland (E. odorata, E. porosa, E. macrocarpa).

 Forests and woodlands with open sclerophyll shrubby understory (SMLR 2). This was suggested by the representative from the SAMDB region. This community overlaps with AMLR.

 Stringybark woodlands.

 High rainfall gum woodlands (including riparian, E. viminalis, E. camaldulensis, swampgum).

 Ecotome transition zones (E. goniocalyx).

 Low rainfall grassy woodlands under production (northern and eastern hills).

 Grassy woodlands.

 Temperate tussock grassland.

 Heathlands and heathy woodlands (including pink gums and blue gums).

 Mallee on ‘A’ calcareous soils (E. oleosa, E. gracilis).

 Water dependent ecosystems.

 Coastal heath.

 Samphire (coastal/subcoastal shrublands) in low energy environment.

 Fleurieu Peninsula swamps.

 Estuaries.

For each vegetation group, the values (both biodiversity conservation and community), reasons for prioritising, existing monitoring programs, amount of investment in vegetation management, drivers (that cannot be managed) and pressures (that can be managed) and expected management outcomes were identified (summarised in Appendix A). If vegetation groups had similar values and expected outcomes they were grouped together, which resulted in 14 broad groups (Appendix A). Of these, 6 groups would be prioritised if the number of vegetation groups needed to be reduced to fit the budget.

1.5 Spatial scale, site selection and stratification of vegetation groups for monitoring

Workshop participants discussed the spatial scale for monitoring of vegetation condition. Some participants highlighted the need for monitoring to be undertaken at subregional or even smaller scales, to match the scale at which they implemented vegetation management and because different landscapes have been impacted in different ways. It was suggested at the workshop that this design would enable the monitoring information to be used to evaluate effectiveness of vegetation management at landscape scales. Workshop participants discussed the guiding principles of this framework, which included the need for landscape-specific management outcomes. The framework did not specifically address the evaluation of the effectiveness of management at project sites.

Several workshop participants indicated that vegetation sampling needed to be undertaken at the NRM regional scale. It was highlighted that this was in line with the guiding principles of this monitoring framework. The rationale for measuring trends in vegetation condition at the NRM regional scale was to inform the community about where and why NRM levy investments are required.

Workshop participants highlighted that some areas of some of the vegetation groups functioned or were valued differently, or were managed for different outcomes. For these reasons, workshop participants indicated that the vegetation monitoring

(10)

5 methods (such as benchmarks) needed to be spatially stratified to account for these differences. The workshop participants suggested that the following factors needed to be considered to stratify the sampling for the monitoring program, resulting in what are termed in this report as stratified vegetation groups:

1. Landscape type and state.

2. Climate resilience adaptation type.

3. Vegetation that has been modified by people versus vegetation that is pristine, or protected for conservation outcomes (if vegetation management targets are different).

4. Vegetation on sloped versus flat areas (if management outcomes are different).

5. Vegetation on the east versus west sides of the Mount Lofty ranges (if management outcomes are different).

6. Vegetation in open versus closed woodlands (if management outcomes are different).

7. Vegetation on nutrient poor soils versus vegetation groups on sandy soils (if management outcomes are different).

8. Vegetation in different types of wetlands (surface water or aquifer fed).

9. Managed versus unmanaged vegetation (if management outcomes are different, e.g. fire management vs non-fire management zones).

10. Vegetation in small versus large patches (if management outcomes are different).

The first 2 stratification factors in the list above are adapted from a landscape framework, which outlines the respective broad management and conservation outcomes for each factor. Andrew West (AMLR NRM region) provided the landscape

framework for the AMLR NRM region as a map, which was based on historic landscape type, landscape states, and resilience to climate change (Appendix B). Landscape types include forest, grassland, mallee, shrubland and woodland. Landscape states are based on whether plant species diversity was higher, lower or typical of what was expected, based on trends in diversity over the past 40 years. Climate change resilience is based on whether system processes needed to undergo repair to adapt, whether both system processes and components needed to undergo some repair to adapt, or whether the system is not able to adapt (e.g. due to sea levels rising on samphires and mangroves) without new management interventions. Andrew West indicated that this spatial layer could be modified to reflect the requirements and scale of the proposed vegetation monitoring framework.

Workshop participants noted that not all of the stratification factors in the above list are relevant to all of the vegetation groups. For example “vegetation in different types of wetlands” is only relevant to wetland communities. Likewise, “vegetation on the east versus west sides of the hills” is only relevant to hill-side communities, which are influenced by the aspect of the hill slope. Some stratification factors are related to the expected management outcomes, such as “vegetation groups that have been modified by people versus vegetation that is pristine, or protected for conservation outcomes”, because vegetation is expected to function differently in farmed versus undisturbed environments.

Workshop participants suggested that based on their knowledge of the expected variance between sites and the predicted change in vegetation condition, between 13 and 30 sites would need to be measured in each of the stratified vegetation groups. The total number of stratified vegetation groups for the monitoring program is 62. Based on the recommended sample sizes, the numbers of stratified vegetation groups that could be sampled are estimated in Appendix A (last column). If between 13 and 30 vegetation condition sites are measured, the total number of sites (including new and existing data) would be between 1,261 and 2,910, which would be monitored once over the 5 year program. These estimates incorporate the first 8 factors (out of 10) listed above to stratify the vegetation groups. The factors that relate to management areas and patch sizes (the last 2 factors in the list above), were not used to stratify the vegetation groups, with the exception of the fire management zones in the stringybark vegetation group. Before the monitoring plan is finalised, detailed maps will be need to be produced to determine how many management and patch size stratification groups would be needed within each vegetation group.

To map the stratified vegetation groups, vegetation extent maps will also be required. These may be sourced from DEWNR’s corporate databases or from databases held by the AMLR NRM Board. Workshop participants noted that there is limited capacity to compile new maps for this new monitoring program and that DEWNR’s native vegetation layer may not include some vegetation in highly modified landscapes. These issues would need to be addressed before the monitoring plan is finalised.

(11)

6 The number of sites to be assessed within each stratified vegetation group would also be influenced by the available budget for monitoring, the expected variance between samples, and statistical analyses. For example, if the number of sites required to detect change is more than can be resourced, fewer stratified vegetation groups may need to be sampled or several of them may need to be combined into broader groups. In addition, power analyses can be used to estimate the number of sampling sites to detect a given amount of change in vegetation condition within each stratified vegetation group. Such power analyses are best undertaken on data from each stratified vegetation groups that will be monitored in the AMLR NRM region. In the absence of such data (i.e. before the start of the monitoring program), other similar vegetation condition data could be used to inform the sampling design. Equivalent data include the BCM collected by the Nature Conservation Society of SA, and/or data collected on Eyre Peninsula (Wiebkin 2013) and South East NRM (McLeay et al. 2013). As new data are collected, power analyses can also be used to review and refine the sampling design.

The possibility of revisiting BCM sites to detect change was discussed by workshop participants, and will also need to be addressed before the monitoring plan is finalised. Workshop participants indicated that the coverage of the existing BCM sites, including the number of stratified vegetation groups, was not adequate to report on vegetation condition at the regional scale.

The review of the BCM data indicated that these sites spanned about 25 per cent of the number of stratified vegetation groups in the AMLR NRM region. The review of the BCM data indicated that some of these sites are randomly distributed across broad areas, but some are focused on project sites, where management has been undertaken. Workshop participants noted that analyses of gaps will identify the spatial coverage of the existing information and new sampling that is required.

Workshop participants noted that randomly selecting the locations of sites (within stratified vegetation groups) would ensure that the vegetation condition surveys would not be biased toward vegetation in either good or poor condition. This would provide data that are representative of the condition of vegetation across the AMLR NRM region. Workshop participants noted that sites for monitoring can be randomly selected from within the mapped polygons for each stratified vegetation group using ArcGIS (e.g. Wiebkin 2013, McLeay et al. 2013). The locations of existing vegetation condition assessments can also be incorporated in these analyses, so that new sites fill the apparent gaps. Workshop participants discussed site selection rules that could be used to ensure that monitoring sites were:

 located in relatively large patches of vegetation

 independent of one another

 easy to access

These rules were not settled during the workshop. Workshop participants noted the importance of the rules that were used in studies in Eyre Peninsula and South East regions (Wiebkin 2013, McLeay et al. 2013), including that sites should be:

 within patches >6000 m2 (or select a smaller area if most extant patches are <6000 m2)

 >110 m from road centrelines and <210 m from road centrelines

 >100 m from the edge of areas of native vegetation (e.g. where vegetation meets paddock)

 at least 1,000 m apart if sampling the same vegetation community/stratification group.

The number of sites that are pre-selected should exceed the number of sites that will be monitored. If possible, 50 sites should be pre-selected within each stratified vegetation group because this would provide alternative sites if some are not accessible (due to remoteness of sites, impassable tracks, weather conditions or lack of approval from landowners), or where vegetation groups at chosen sites are different to those recorded in mapping data. The 50 randomly pre-selected sites should be labelled sequentially. Access and directions to each site should be checked and sought (i.e. approval from owners of private land) before the survey. Sites that are not accessible should be discarded and access to the next site on the list should be sought until access is confirmed for the required number of sites.

(12)

7 Metadata on the location of each site should include:

 unique identification number

 land owner surname

 land owner name

 land owner address

 landholder’s contact detail

 section number

 hundred name

 stratified vegetation group

The locations of sites should be uploaded into field GPS units, and maps of the selected sites (together with cadastral or Forestry SA maps) should also be provided to field teams.

1.6 Indicators and benchmarks

Workshop participants agreed that indicators and benchmarks should be selected to reflect broad regional-scale values, pressures and expected management outcomes for each stratified vegetation group. Different stratified vegetation groups may have different indicators and benchmarks. Potential indicators for all stratified vegetation groups are included, as suggested by workshop participants, in Appendix C. Workshop participants did not allocate weights to each indicator. Similar work has been done by the NCSSA for the BCM method, Wiebkin (2013) and McLeay et al. 2013, and this is required before the program is finalised.

Benchmarks will be developed in consultation with technical experts, or analyses of existing data or they may be modelled once the data have been collected for this project. Workshop participants noted that there is no capacity to survey stratified vegetation groups to develop new benchmarks before the surveys are undertaken.

Where existing vegetation condition data are suitable for inclusion in this project, new benchmarks will be used to ensure that site assessments are standardised between existing and new data, and between sites and within different stratified vegetation groups. New benchmarks will be tailored to specific survey methods, which may differ between existing and new monitoring methods.

Workshop participants from SAMDB regional staff indicated that BCM assessment information is an effective tool to

communicate the condition of vegetation to their community. They indicated that the number of indicators in the BCM method (13 in each vegetation community) is comprehensive and inclusive of several components of vegetation condition. They recommended that the AMLR monitoring program include a similarly comprehensive suite of indicators. Workshop participants noted that the number of indicators used by the AMLR monitoring program would need to be balanced against the amount of time required to assess each site, and the budget.

Several workshop participants suggested that an indicator of fuel load be considered for all flammable systems.

1.7 Methods

Detailed methods were not developed in the workshop, but the workshop participants agreed that the methods should be appropriate and efficient for measuring the chosen indicators. Guidelines for the development of the methods are provided in Appendix C.

Workshop participants from SAMDB indicated that there was some variation in vegetation condition assessments (using BCM methods) recorded by different observers. For this reason, the methods used in this monitoring program should be objective, quantitative and easy to understand.

(13)

8 Workshop participants indicated that the timing of sampling should be relevant to the timelines and schedules of expected management outcomes. It is likely that the resources for this project will allow for sites to be monitored once every 5 years.

1.8 Next steps

Subject to approval and resourcing being made available, the next steps for the project are listed below.

 Staff from the AMLR NRM region will decide which vegetation groups and stratification groups will be assessed.

 Staff from the AMLR NRM region will decide which indicators and benchmarks will be used (based on the suggestions in Appendix C). Indicators and benchmarks will reflect specific values of each system. For example woodland bird habitat features may reflect biodiversity value where woodland birds are declining.

 Analyses of existing information to assess where new monitoring sites are required.

 Methods will be developed for the new monitoring sites and the time required to complete field surveys will be estimated.

 The number of sites able to be resourced by this project will be calculated (based on selected methods) and the number of stratified vegetation groups to be monitored will be reduced, if required, to fit the budget (see vegetation groups prioritised by management investment in Appendix A)

 Field protocols, datasheets and monitoring sites will be prepared (considering results of gap analyses).

 Contractors will be engaged to trial the vegetation condition monitoring. Participants recommended (on the basis of management investment) that the trial focus on the samphire and grassy woodland systems.

 New field data and existing data will be analysed, and benchmarks will be applied to monitoring data to assess regional vegetation condition of the 2 trial vegetation groups.

 The monitoring design and protocols will be reviewed.

 An interim report will be produced to report on the trial.

 The remaining stratified vegetation groups will be monitored over the subsequent 3 years.

 Annual reports and report card content will be produced for all stratified vegetation groups.

 The AMLR NRM Board will lead the production of the report cards, which will be accessible to all members of the community.

 The remaining stratified vegetation groups will be monitored every 5 years.

 As resources become available, additional sites (such as those in project areas) and vegetation groups could be incorporated into the program to answer specific vegetation condition questions.

3 Appendix

A. Proposed vegetation groups for monitoring

Table of selected vegetation groups, outlining why they are valued for conservation, production and other reasons, whether they are priorities, existing monitoring programs, existing management investments, drivers and pressures that impact the vegetation groups, expected management outcomes for each vegetation group, and the proposed stratification of the vegetation groups. The extent of some vegetation groups only exists in a subset of available stratification types. For example, the extent of wetlands only exists in one landscape type and one climate resilience type (which overlaps completely with the landscape type). Within the single climate resilience type, there are two water-table swamp types, meaning that for wetlands only two stratification groups are relevant. These stratifications are approximate, and are based on the draft landscape map in Appendix B and extent maps of vegetation held by DEWNR. The number of stratification groups may change when all extent maps have been chosen. Vegetation groups labelled with * receive relatively more management investment, and these groups would be prioritised if the number of vegetation groups needed to be reduced to fit the budget.

The ‘vegetation groups’ refer to a range of fine and broad scale vegetation associations and landscapes that are valued for a range of social, ecological and economic purposes. The range of scales means that they do not all align with a single vegetation classification system, and that there is spatial overlap of some groups.
