Preamble This handbook was developed out of a need to implement a system to routinely operationalize the ‘T’ in VAST i.e. Transitions in the in Vegetation Assets, States and Transitions framework (Thackway et al., 2007, Thackway and Lesslie 2008). The handbook is designed to assist practitioners compile historical and contemporary information on the responses of native plant communities at sites to the impacts of land use and land management practices over time.

Almost all vegetation in Australia has been affected by changes in land use and land management practices since first contact. A historical record of the responses of native plant communities to these pressures or disturbances can be used for several purposes: assessing the extent and condition of key assets, prioritising investment in key localities to redress ecological impacts associated with specific time periods, improved targeting of scarce public funding and monitoring and evaluating the outcome of this investment, assisting land managers to make improvements in land management practices to meet wider community social, economic and environmental goals.

It is acknowledged that there is a plethora of ways that native vegetation has been managed, and continues to be managed to meet a wide range of goals. Therefore the disturbance history of every site will be different, although at the local level some sites are expected to share histories at the bioregional level.

Across Australia, land use and management activities have transformed much of the forest and woodland landscapes associated with the Great Dividing Ranges; central Tasmania and south west of Western Australia with large areas cleared and converted to crops and improved pastures (Thackway and Lesslie 2008). Even in the absence of clearing, most of Australia’s arid and semi-arid rangelands have been transformed ecologically due to the impacts of livestock production over 150 years or more (Williams and Price 2010). The resultant landscapes are a diverse spatial mosaic of fragmented and modified native vegetation and converted and replaced vegetation cover types (Thackway and Lesslie 2008).

Documenting the historic and contemporary use and management of a site and assessing their effects on vegetation condition is a complex task. This handbook sets out a systematic approach for compiling and assessing such quantitative and qualitative data and information as well as personal communications to determine changes in the condition of native plant communities over time.

Sometimes the management history of a site can be determined from historical records and/or via observed characteristics of the vegetation. The effects of these activities can also sometimes be ‘read’ at sites from the presence of exotic species relative to the native species that remain, the lack of an overstorey or an understorey, the presence of soil erosion or of soil deposition, the lack of an age class in growth form (e.g. old trees), the height of the understorey, the density of particular species in the understorey indicating a recent fire. For this reason, this handbook provides general guidance only.

An early draft of this handbook was developed during 2011 as part of a Sabbatical Visiting Fellowship with the Australian Centre for Ecological Synthesis and Analysis, a facility of the Terrestrial Ecosystem Research Network. i

Introduction The use and management of native plant communities results in characteristic impacts on the extent and condition (fragmentation and modification) of vegetation structure, species composition and regenerative capacity. Landsberg and Crowley (2004) describe these impacts as pressure metrics or indicators, which include grazing, clearing, weed invasions and inappropriate fire regimes. Williams et al., (2002) in assessing the key issues in resource management at the regional level in Australia defined a range of vegetation and ecological function indicators are impacted by use and management. Doherty (2009) in a review of the conservation value of regrowth native plant communities for biodiversity highlighted the importance of understanding the impacts of use and management of native plant communities (vegetation structure, species composition and regenerative capacity).

McGlone (2000) points out that information on history of use and management plays an important role for developing a template for how we might manage our future natural environments, noting that where information is documented and analysed at sites it provides a continuous record of change.

Land planners and managers require information on the status, change and trend of these impacts on vegetation types for environmental reporting, land use trade-offs, and to inform future land use scenarios. Over the last decade considerable progress has been made in developing information systems for compiling regional scale datasets of the current extent and condition of Australiaâ&#x20AC;&#x2122;s vegetation types, relative to a pre-European unmodified state. However, little work has yet been done to develop a method for compiling data and information on the way land use and land management practices have transformed, and continue to transform the extent and condition of Australiaâ&#x20AC;&#x2122;s vegetated landscapes. The absence of a consistent approach to report transformations of native vegetation over space and time remains a source of contention, and even conflict, between those involved in conservation and protection and those involved in sustainable land use and management of native vegetation.

This handbook presents a system for recording site-based transformations of Australiaâ&#x20AC;&#x2122;s vegetated landscapes since settlement. The system utilises observed and/or measured information on changes in land use and land management practices and their impacts on vegetation structure, species composition and regenerative capacity over time.

Fundamental to the approach is access to credible published sources of information that describe where, when, and what changes in land use and land management practices were used to manage the vegetation. The sources of this information are multidisciplinary, including land use histories, remote sensing, and several branches of ecological science; landscape, vegetation and restoration.

Much of the historic information is qualitative, compared to contemporary information, which is mostly quantitative. A key challenge for users of this handbook is to compile information which is generally piecemeal, not easily discoverable, poorly organised and to a large extent non-digital.

Information is held in disparate places, sources and forms.

Ten benefits of tracking the effects of land management practices 1) Tracking land management practices over time at well-chosen representative sites offers a least cost method of monitoring and modelling change and trend in vegetation condition. This is because native plant communities generally respond in predictable ways to land management practices.

2) Tracking the responses of native plant communities to land management practice e.g. interventions, can give insight into rates of change in the short term following one-off impacts and in the long term after repeated disturbances and interventions e.g. strategic grazing.

3) Tracking land management practices and the observed and/or measured responses of plant communities can provide key information on the timing of changes and trends in vegetation condition, which is critical for modelling local, landscape and boarder regional patterns.

4) Repeating a standardised monitoring method enables land managers to investigate which land management practices effect the vegetation condition indirectly either by targeting the regenerative capacity, or directly by targeting the species composition and vegetation structure.

5) Creating a historical record of land management practices provides important evidence of the effects of everyday and routine land management practices and helps decision makers understand the responses of vegetation to these practices: a) removing trees, shrubs and/or grasses e.g. clearing, pulling, pushing, ploughing b) replacing trees, shrubs and/or grasses e.g. revegetating, restoring c) managing the health and vitality of vegetation e.g. rolling, pruning, lopping, staking, slashing, fertilising, grazing, bailing, ploughing, rehabilitating, burning, poisoning and pulling d) managing waste and residues from vegetation e.g. burning felled trees, burning shrubs and grasses e) monitoring the response of vegetation to the above.

6) Documenting a historical record enables land managers to assess the likelihood of sites in similar environmental settings behaving in similar patterns in the short, medium, long term and very long term for least cost.

7) Tracking key indicators of the response of the vegetation and the environment, relative to a reference state (e.g. pre-European plant community), provides a valuable tool for evaluating progress toward a target or distance from a reference. Change that is positive is that which is trending toward the reference state, whereas change that is negative is that which is trending away from the reference state.

8) Tracking gains and losses in key indicators that are linked to land management practices provides insight into those practices which maintain, enhance, restore or remove a plant community.

9) Tracking gains and losses in key indicators that are linked to the fundamental components of vegetation condition i.e. regenerative capacity, species composition and vegetation structure can be used to understand, modify or enhance or replace native vegetation: a) Indicators of regenerative capacity include soil hydrology, soil structure, soil nutrients, soil biota, fire regime and the reproductive potential b) Indicators of species composition include species richness and vegetation functional groups in the overstorey and understorey c) Indicators of vegetation structure include height, cover and structural diversity or age of the dominant life stages /age classes of components of the overstorey and understorey.

10) Tracking the interactions between the prevailing environmental conditions e.g. long term average monthly rainfall and the land management practices on indicators of vegetation condition will establish insights into cause and effect. By recording these interactions it is easier to assign causal effects due to anthropogenic and natural environmental conditions. In some cases the interactions will result in inadvertent change and trend.

Aims of this Handbook

The aim of this handbook is to provide a structured way to record observed and/or measured responses of native plant communities at sites to historic and contemporary land use and land management practices relative to a reference state. This approach is premised on the idea that the disturbance history of a site strongly influences opportunities for improvements in vegetation condition.

The approach set out below aims to operationalize the ‘Transitions’ component of the Vegetation Assets States and Transitions (Thackway and Lesslie 2006, 2008). This is enabled by defining a ‘reference site’ (i.e. least ecologically modified native vegetation – assumed pre-European) and a ‘transformation site’ for each plant community.

A ‘reference site’ defines what was plausible at a ‘transformation site’ in terms of the three components of vegetation condition; species composition, vegetation structure and regenerative capacity. A ‘transformation site’ is the same plant community as the reference site but whose three components of vegetation condition may have been changed over time as a result of modern anthropogenic influences i.e. use and management.

To assist in fulfilling this aim, a site-based proforma datasheet (Appendix 1) is provided as a guide the systematic compilation of the historical record of a plant community over time, compared to a site-based reference state.

For the purposes of compiling and assessing vegetation and environmental change at a transformation site, it is assumed that the primary driving natural variable, common to the reference and transformation sites, is average monthly rainfall throughout the historic record.

Location of the site Source of geo-code Reliability of the geo-code Date of the observation and/or measurement Source of date/year Reliability of the date/year Land management practices for each approximate year Source of land management practices Reliability of the land management practices Effects and impacts of land management practices on ecological function and vegetation condition, 11) Source of effects and impacts 11. Reliability of the observed and/or measured effects and impacts of land management practices. 22 indicators of vegetation and environmental transformation are used as a checklist to guide the search for, and compilation of, information on the effects and impacts of the land use and management on a plant community over time.

The sequence of recording the information is important. Always start with the location followed by the year of observation and measurement, then compile land use and land management practices and the effects and impacts of land management practices on ecological function and vegetation condition.

Contemporary observations and measurements can be recorded as year/month/day, whereas historic observations typically only have the year. Try to avoid general observations e.g. mid 1880s.

Where no other date is available record this as 1885.

It should be noted that this process may require several attempts at getting all the information in the right historical sequence and sorting out what are the important observations in regard to describing historic and contemporary changes in regenerative capacity, vegetation structure and species composition that are due to land use and land management actions/practices.

It should be noted that land use and land management practices can have cumulative effects over time. Also important are the interactions between natural events e.g. drought, fire and flood and the effects on the vegetation of land use and land management actions/practices. Record all major natural events as part of the chronology. Observations and/or measurements should be recorded relative the reference state. The VASTTRANS site-based datasheet at Appendix 1 specifies these contextual site-based geographic, vegetation and environmental attributes and how they should be recorded.

The process of compiling information on the effects of use and management of a nominated site should refer to the 22 indicators as a checklist. These 22 indicators describe the key factors which land managers target to assess, maintain, enhance, restore, remove and replace with non-native vegetation e.g. plantations and crops or remove and replace with non-vegetated cover types e.g. built infrastructure, pavement or gravel surfaces.

Why monitor?

Monitoring involves the regular collection of information at the reference and transformation site using the same method so that it is possible to track changes and trends in the key 22 indicators of the condition of a plant community and the summary components of the plant community i.e. regenerative capacity, vegetation structure, species composition and the total vegetation condition.

It is an important on-going management tool that needs to be standardised, repeatable, verifiable and recognisable. For best results monitoring should occur continuously over a number of years at the same time using the same method of observation and measurement.

The section below How to Monitor describes a photo-point approach, which provides a basis for recording several of the structural indicators at sites.

Critical to the method is to develop an ecological understanding the interactions in the historic record between historic rainfall and land management and the responses of the indicators and the components of vegetation condition for each plant community.

Recording the disturbance history of a site can inform future land management options.

What is a reference state?

A reference state represents an unmodified state against which a transformation site can be compared. Components of vegetation condition at a reference site i.e. vegetation structure, species composition and regenerative capacity are comprised of groups of indicators, where each component is assigned 100%, i.e. unmodified. Observed and/or measured changes in 22 indicators for each year in the historical record at a transformation site range from 0 to 1; where 1 represents a natural unmodified plant community as it would have been without post settlement human intervention, and 0 is where that ecological function is absent (Cosier and McDonald 2010).

Why use a reference state as a benchmark?

Describing a transformation site or modified vegetated landscape against a reference state does not imply or suggest that site or landscape should be returned to its pre settlement condition or state.

Rather, a reference state simply provides a common base to measure change against a common denominator (Cosier and McDonald 2010).

Reference condition or state is used extensively in the scientific literature to describe a standard or benchmark against which to compare the condition of an ecosystem or vegetation and habitat type (Parkes et al., 2003, Stoddard et al., 2006). In complex ecosystems it also provides an appropriate measure for describing where ecosystems are approaching critical thresholds (Scheffer et al.,. 2001, Walker and Meyers 2004).

Where in the landscape to select sites?

Choose sites in areas which are representative of the bioregion i.e. representative of the characteristic soil landscape elements. Select a site (reference and transformation) in the same landscape element i.e. sharing the same soil, plant community and landform.

How to define a site?

A site is an area of uniform soil and topographic features and pre-European vegetation communities considered to be representative of a dominant landscape element. A landscape element includes e.g. plains, depressions, flats and lower slopes, mid slopes, upper and ridge lines. The geology and soil type is also relatively uniform throughout a site. The pre-European plant community of a site is also relatively uniform throughout the area.

The geo-location of a site and its shape and area remain constant back in time, now and into the future.

The use and land management of the vegetation at a site will change over time but are expected to be uniform over the extent of a site at different time intervals. It is important to record changes in use and management of the site over time and their effects on the respective components of vegetation condition i.e. regenerative capacity, species composition and vegetation structure.

How to select and describe a site?

Limit the size (length and width) of a site so that a site represents a narrow range of variation i.e. vegetation, soil, slope and aspect. Aim for uniformity throughout the site assuming the use and management has been homogeneous.

There are number of ways to mark a site. A commonly used method is to establish a permanent marker at the site e.g. a star picket to help relocate the site.

Use a GPS and/or Google earth to record the location of the site and distance from key features of the site. In addition, mark the site on a topographic map and or on a farm plan or vegetation plan.

Where practical and with the resources available select and describe two sites in an area: 1. Choose a site which is representative of high impact use and management on the plant community i.e. the native vegetation has been fragmented and replaced. This site may be described as a treatment 2. Choose a site which is representative of low impact uses and management on the plant community i.e. the native vegetation has persisted since first settlement. The native vegetation at such sites may have been minimally modified as a result of land use and management pressures. This site could be described as a control.

What year to start recording a site chronology?

Start the chronology in the year when explorers first traversed the area/region. NB: the path taken by an explorer need only be in the vicinity and be indicative of the soil landscape /bioregion and not be actually in the area of the site/s.

How to record time at a site?

Document the start and finish dates of all major land use and land management changes that have affected the plant community at the site.

Contemporary observations and measurements can be recorded as year/month/day, whereas historic observations typically only have the year. Try to avoid general observations e.g. mid 1880.

Where no other date is available record this as 1885.

Where the use and management of plant community is observed to be generally the same (e.g. sheep grazing at 1 sheep per 5 ha) for a period (e.g. started in 1835 and ceased in 1910); record the start and finish years of the practice.

Where the use remains the same (e.g. grazing native vegetation) and the management regime/practices change then record the start of the changes in management regime/practices (e.g. started set stocking with 1 sheep per 2 ha in 1935 and changed to cell grazing in 2005), then record the start and finish years.

Where information is available on the season of the land management practice, then record year/month/day.

How to monitor For best results monitoring should occur continuously over a number of years at the same time using the same method of observation and measurement.

There are many different methods of monitoring change over time. Perhaps the most commonly used monitoring approach is that of photo-points, as they are relatively quick and simple and require a minimum of training and skills.

Once a site is selected a permanent marker from which ground-based photos can be taken and retaken over time is established. Photo-points do have clear benefits however unless site methods are well designed they offer only limited information about change over time.

Many state and territory agencies and university and CSIRO researchers have developed site-based methods for monitoring native vegetation. These protocols vary in the types and levels of detail that are collected. Where possible use available state and territory guidelines and protocols. Two examples of a photo-point methods are: (referenced under SA and WA Government Systems).

What land use and management information to record?

What land use information to record?

Land use is defined as …

The purpose to which the land cover is committed. Some land uses, such as [intensive] agriculture, have a characteristic land cover pattern and usually appear in land cover classifications. Other land uses, such as grazing native vegetation, are not readily discriminated by a characteristic land cover pattern. For example, where the land cover is woodland, land use may be timber production or nature conservation.

(ACLUMP 2010a)

Table 1 presents a list of national land uses classes and codes (ABARES 2011) for use reclassifying information compiled into Section 10 of Appendix 1 and ‘filling in’ the VASTTRANS spread sheet (not included in this Handbook). These classes and codes a known as the Australian Land Use and Management (ALUM) classification system and have been developed by the Australian Collaborative Land Use and Management Program (ACLUMP), which comprises representatives of the Australian and State and Territory land management agencies.

What land management practice information to record?

Land management practice is defined as the approach taken to achieve a land use outcome—the ‘how’ of land use (e.g. grazing a native woodland, such as raking fallen timber, burning windrowed fallen timber, spraying weeds, adding superphosphate). Some land management practices (e.g. clear felling native forest plantations and direct seeding) may be discriminated by characteristic land cover patterns that are be linked to vegetation and environmental indicators.

For the purposes of the VASTTRANS approach each ALUM land use class can be described by up to five dominant land management practices that are observed and/or measured to operate at the site in a year.

Table 2 presents a preliminary list of land management practice classes and codes for use reclassifying information compiled into Section 10 of Appendix 1 and ‘filling in’ the VASTTRANS spread sheet (not included in this Handbook). These classes and codes a known as the Land Use and Management Information System (LUMIS) and are being developed in consultation with ACLUMP (Bureau of Rural Sciences 2006, ACLUMP 2010b).

To illustrate the need for a standardised national list of management practices, Appendix 2 presents a list of land management practices compiled by (Kirkpatrick and Bridle, 2008). This list, was compiled as part of a study of the history of use and management of sheep runs and their effects on the vegetation and environment in Tasmania’s midlands, shows the diversity of management practices which pertain to grassy woodlands in one bioregion. The value of such lists at the site level come when these land management practices are reclassified using the LUMIS framework in Table 2.

Understanding natural and human caused disturbances Short term (1-2 years) repeated observations of these data types at sites, may not show obvious changes where the causal factors are natural disturbances including, grazing and browsing by native animals, and recovery from cyclone, fire, drought, storms. Many human actions such as revegetation and rehabilitation, fencing out of domestic livestock, controlling weeds, reintroducing fire, adding or stopping fertilizer also may not show obvious changes in the short term. Short-term obvious responses do occur especially where the plant community has been highly modified via natural catastrophic events such as cyclones, wildfire, floods and storms. Short-term responses to human actions such as recovery from clear felling trees and shrubs, ploughing and over grazing with domestic and/or native animals or a combination of both may also be observed and/or measured.

Medium (around 5 years) and longer term (around 10-20 years) repeated observations at sites, generally do show obvious changes. These changes include recovery from disturbances caused by cyclones, fire, drought, storms and human use and management actions (such as revegetation and rehabilitation, fencing out of domestic livestock, controlling weeds and feral species, reintroducing fire, reintroducing flooding of wetlands, mitigating soil erosion, thinning of dense vegetation).

The VASTTRANS site-based datasheet at Appendix 1 defines these contextual site-based environmental attributes and how they should be recorded.

Why use indicators to describe impacts of land use and management?

The science of ecosystem health indicators makes the task of accounting for the transformation of vegetated landscapes tractable. Cosier and McDonald (2010) noted that ecosystem health indicators are quantifiable and transparent measures of the characteristics of the ecosystem that can detect change. These authors also observe that with careful selection, indicators are capable of providing a simple measure for a complex system.

Figure 1 shows 22 indicators forming part of the VASTRANS information hierarchy for deriving scores of vegetation and environmental transformation for each year in the historical record. That is, scores from the 22 indicators below are aggregated into 10 attribute groups. The scores from these 10 attribute groups are aggregated into 3 diagnostic attributes. The scores from these 3 diagnostic attributes are weighted and then aggregated into a single score vegetation transformation for each year in the historical record.

10

What contextual site-based environmental information is important?

Regional scale natural environmental events such as tropical cyclones, wildfires and droughts can have profound effects on vegetation dynamics and provide insights into the response of natural vegetation systems. Only when these patterns and processes are understood is it possible to understand observed and/or measured impacts of land management activities on ecosystem function. It is vital therefore to take note of anomalies in the monthly average rainfall record e.g. droughts and prolonged periods or seasons of above and below average rainfall.

It is vital to understand and describe the siteâ&#x20AC;&#x2122;s reference state using the following environmental attributes and regimes: climate and rainfall, geology, soil, landform and position in the landscape, hydrology and fire.

The system for describing and recording above attributes using the VASTTRANS indicators is presented below.

The VASTTRANS site-based datasheet at Appendix 1 defines these contextual environmental attributes and how they should be recorded.

What vegetation structure and species composition information is important?

The minimum information necessary to describe the effects of use and management practices on plant communities involves the collection of six types of data at each site: 1) 2) 3) 4) 5) 6)

Dominant growth form (per stratum, if more than one stratum is present) Cover (per stratum, if more than one stratum is present) Height (per stratum, if more than one stratum is present) Age structure or structural diversity (per stratum, if more than one stratum is present) Dominant species (per stratum, if more than one stratum is present) Functional traits of species groups (per stratum, if more than one stratum is present).

It is vital to understand and describe the reference state for attributes of vegetation structure and species composition at the site level.

The system for describing and recording above attributes using the VASTTRANS indicators is presented below.

The VASTTRANS site-based datasheet at Appendix 1 defines attributes of vegetation structure and species composition and how they should be recorded.

Where other information is available for biomass and species density classes, these can be useful for understanding changes in several indicators of vegetation structure and species composition.

11

How to describe vegetation transformation using VASTTRANS indicators?

A review of the ecological literature that describe the impacts of land use and management on the regenerative capacity, vegetation structure and species composition of native plant communities, identified 22 core attributes which generally apply across Australia’s bioregions, Table 3.

The 22 core attributes correspond with the VAST diagnostic attributes (Thackway and Lesslie 2008) of regenerative capacity, vegetation structure and species composition.

The 22 core attributes serve two purposes: 1) Site-level vegetation transformation At present this handbook handles only site level data compilation i.e. 1a below a) a framework to guide the compilation of likely relevant evidence of the probable responses of plant community i.e. changes in regenerative capacity, vegetation structure and species composition due to changes in land use and management practices Information on the impacts of use and management of vegetation on the22 core attributes can be derived from site-based sources e.g. changes in species composition, changes in age class or structural diversity or changes in grazing pressure on grazing sensitive plant species.

A VASTTRANS datasheet (Appendix 1) is provided as a convenient tool for recording information on:  Approximate year  Source of year information  Land use (ALUM)  List of land use (LU) and land management practices (LMP)  Source of LMP information  Descriptions of the response of native plant communities to LU and LMP (i.e. impacts on species composition, veg structure and regenerative capacity) informed by the22 core attributes  Source of response information b) a framework for scoring 22 indicators of the observed and/or measured impacts of land use and management practices on regenerative capacity, vegetation structure and species composition.

A separate VASTTRANS spread sheet can be provided as a convenient tool for scoring and graphing the 22 indicators.

An example of a resultant graph is presented in Figure 2.

2) Landscape-level vegetation transformation At present this handbook handles only site level data compilation i.e. 1a above a) a framework for compiling relevant spatial evidence of the likely responses of a particular plant community i.e. changes in regenerative capacity, vegetation structure and species composition due to changes in land use and management practices.

Spatial information on the impacts of use and management of vegetation on the core attributes can be derived from landscape level sources e.g. maps of extent of tree clearance, trends in grazing extent and density, trends in woody or ground layer vegetation, changes in the extent and timing of prescribed burning. b) a framework for modelling spatial information of the observed and/or measured impacts of land use and management practices on regenerative capacity, vegetation structure and species composition

The VASTTRANS site-based datasheet at Appendix 1 defines these contextual site-based environmental attributes and how they should be recorded.

17

What are species functional groups?

Cummings and Reid (2008) describe 12 species functional groups (Table 5). Land use and management practices maintain, modify by reducing or removing or modify by enhancing or restoring the number and densities of species functional groups listed in Table 5. Changes made to species functional groups generally reflect the values of a land manager and of the wider society.

Depending on a land managerâ&#x20AC;&#x2122;s purpose for managing a site, various mixes and densities of these 12 functional groups of the native vegetation are maintained, modified, removed and/or replaced.

Records of land management practices and on-ground actions over time generally give insights into what changes have been made to alter the natural ecological function of a site and the desire of successive land managers to derive an altered mix of ecosystem services from that delivered from intact native vegetation (Yapp et al., 2010). Of course the reverse is also true, where a land manager will invest resources (private and public) to rehabilitate and restore the natural ecological function of a site (resilience) with the aim of reinstating the natural mix of ecosystem services, including biodiversity conservation that can be expected from intact native vegetation.

What sources of information are helpful?

There are a wide range of sources of information that are useful for compiling observed and/or measured responses of a plant community at a site and the associated historic and contemporary land use and land management practices. These include quantitative and qualitative data and information as well as personal communications. Environmental history and experimental ecology offer valuable insights to determine changes in the condition of plant community over time. Land manager journals and plans of management are useful compendiums of information.

Preferably observations or measurements should be based on published sources e.g. newspapers, books, reports, journal papers, maps, aerial photos and satellite images and websites.

Government funded, standardised land evaluation, ecological and vegetation surveys usually provide quantitative time bound observations and measurements which can act as â&#x20AC;&#x2DC;book endsâ&#x20AC;&#x2122; within which to sequence less quantitative observations and personal communications.

The preferred way to cite published sources is to use the standard Oxford method for recoding citations.

Much historical information is in bits and pieces, and much of it is useful, even though it hasnâ&#x20AC;&#x2122;t been peer-reviewed. For example, a land holder might have good land management practices information in farm records, but no ecologist has ever seen it. Such information in the hands of an ecologist, can generate new understanding of the impact of management decisions in transforming our landscapes. The preferred way to cite an unpublished source is to state the name of individual, the organisational affinity of the individual and the date of the observation e.g. John Smith, pers comm, May 2010, owner of Mulga Flats 1963-2001.

19

How to record the reliability of sources of observations or measurements?

There are many valid sources of data and information some quantitative and some qualitative.

Attribute types include geo-spatial, temporal and thematic. Information (i.e. measurements and observations) sources that are based on primary sources and measurements are the most reliable; these are quantitative. Those measurements and observations that are based on secondary and tertiary sources and measurements or which are based on anecdotal information and cannot be corroborated and validated or repeated are the least reliable; these are qualitative.

Each attribute type is assigned a code for ease of scoring the reliability of the source information.

Table 4 provides descriptions of three types of attribute information and how to attribute scores of reliability to these information using the VASTTRANS system: 1. Geo-spatial precision (geo-location). codes 1-3 2. Temporal precision (year of observation) codes 4-6 3. Theme accuracy (i.e. land use, land management practices, effects of practices on the components of vegetation condition) codes 7-9 Information sources assigned low scores (i.e. 1, 4 and 7) indicate high reliability where as high scores (i.e. 3, 6 and 9) indicate low reliability across the attribute types.

Figure 3 illustrates the sources of relevant thematic information for a site however such information must be assessed and scored using the reliability scores. Issues to consider include granularity and equivalence of that broader geographic and ecological information to the ecological and land management history for the site in question.

Conclusions Documenting the historic record of land use and management at a site and assessing the effects on vegetation condition need not be a complex task. This handbook sets out a systematic approach for compiling and evaluating such quantitative and qualitative data and information as well as personal communications to determine changes in the condition of a plant community over time.

Results for sites completed during the authorâ&#x20AC;&#x2122;s Fellowship with ACEAS and CSIRO are posted on ACEAS Portal http://aceas.org.au/portal/. Guidelines of how to use the ACEAS Portal are presented in Appendix 3.

Click on the ‘Vegetation Transformation Study Sites ’ Click on the lolly pops depicting each VASTTRANS site Zoom in to the site using the Google Earth map to see the landscape context for the site, the land and vegetation cover Scroll down past the graph you will see the information underpinning each graph: a. Metadata for the site b. Description of the site using 12 core attributes for describing the transformation of a native vegetation community relative to its reference state: 1) Location of the site, 2) Source of geo-code, 3) Reliability of the geo-code, 4) Date of the observation and/or measurement, 5) Source of date/year, 6) Reliability of the date/year, 7) Land management practices for each approximate year, 8) Source of land management practices, 9) Reliability of the land management practices, 10) Effects and impacts of land management practices on ecological function and vegetation condition, 11) Source of effects and impacts, 12) Reliability of the observed and/or measured effects and impacts of land management practices. 22 indicators of vegetation and environmental transformation are used as a checklist to guide the search for, and compilation of, information on the effects and impacts of the land use and management on a plant community over time c. Spread sheet representing the effects of the land management practices on the 22 transformation indicators. Each indicator is scored from 0 to 1 for each year of the historical record; where 1 represents the reference state for each vegetation and environmental indicator and 0 is where that vegetation indicator and/or ecological function is absent. The spread sheet is used to sum and weight the indicators into the respective components of vegetation condition i.e. regenerative capacity, species composition and vegetation structure. The weighted components of for vegetation condition are then added to produce a single transformation index of vegetation condition for each year of the historical record. The results are graphed and annotated to show the response of the plant community under different land use and management regimes.

The aims of the website are to present information about the transformation of a plant community at selected site including:  

 

Location and spatial context of the site using Google Earth Graphical result showing the transformation of a plant community at a site i.e. changes and trend over time. The total vegetation transformation index is comprised of weighted indices for the components of for vegetation condition; regenerative capacity, vegetation structure and species composition Metadata for the site An historical record of use and management and its positive and negative impacts/effects on vegetation condition relative to a reference state for that vegetation community.
