National Vegetation Information System NVIS Products for SoER 2006 Major Vegetation Groups Changes and Reservation ERIN, September 2005 Aims 1. To identify the change in each Major Vegetation Group (MVG) from pre-1750 to the present (“extant” vegetation). The output compares the area of each MVG using the pre-1750 data with the most recent present vegetation data. 2. To compare the presence of each MVG in nature conservation reserves across Australia. 3. To communicate the results to selected SoER theme author(s). Materials and Methods Input Datasets The analyses used three input datasets, viz: NVIS Stage 1, Version 3 (further details below) Interim Biogeographic Regionalisation of Australia (IBRA) Version 6.1 – Regions. Collaborative Australian Protected Areas Database - CAPAD 2004 Terrestrial The NVIS Dataset The origins of the NVIS dataset have been described in NLWRA (2001). Several analyses were performed on a national dataset compiled from detailed NVIS data and coarser, gap-filling data. This included a comparison of each present vegetation type with a nominal currency of 1997 against the pre-1750 occurrence of each. Since the 2001 assessment, further improvements have been made to the NVIS standards (ESCAVI, 2003), internal database consistency and extent of coverage of the detailed data. State and Territory custodians have converted more detailed vegetation mapping into the NVIS format, including some new mapping. In May 2004, ESCAVI agreed to re-supply NVIS to support national State of the Environment Reporting and other uses. ERIN has re-compiled extant and pre-1750 layers for the continent on a State-by-State basis. The nominal date for the NVIS extant coverage is 2001 to 2004 (except for NSW which is 1997-2004). The extant layer covers 95% of the continent, with the remainder filled in by coarse data (Table 1; Fig 1). Similar improvements have been made to the NVIS pre-1750 theme (Table 1). 1 National Vegetation Information System Table 1: Coverage of the detailed NVIS dataset. NVIS Stage 1, V.1 Pre-1750 Vegetation 71% Present Vegetation 78% NVIS Stage 1, Version 3 77% 95% The NVIS quality assurance procedures have been applied to all State and Territory vegetation types except those from NSW. Much of the data conforms to or exceeds the target scales of 1:100,000 for the Intensive Landuse Zone and 1:250,000 for the Extensive Landuse Zone. Vegetation descriptions have generally been supplied at the NVIS Level 5 or 6, meeting the target level of detail. It is anticipated that a comprehensive data quality and gap analysis will be performed on the re-supplied NVIS. Fig 1: [Draft] key map of sources for the NVIS Present Vegetation theme. (A similar key map is in preparation for the NVIS Pre-1750 Vegetation theme.) Limitations of NVIS The version of the NVIS dataset used in this analysis has a number of limitations, the chief of which are: The NVIS Stage 1 dataset is intended to report on native vegetation, so the data for MVGs 1 to 23 inclusive are suitable for analysis. Data relating to nonnative and non-vegetated types are included in NVIS, where available. These are useful for context and cartography, but they are not suitable for analysis in this version of NVIS. 2 National Vegetation Information System Large areas of NSW have not been updated, so the nominal date of the present vegetation theme remains 1997. Note that the vegetation typing for the old NVIS data for NSW has not been through the NVIS quality assurance procedure. This version of NVIS is an update of the previous version with better data. It is generally not comparable with the earlier version and should not be used as quantitative evidence of vegetation change. Custodians were unable to supply a pre-1750 layer for SA and large parts of NSW. The pre-1750 vegetation typing supplied by the custodians was sometimes different to that of the present vegetation. That means that the two themes are not always strictly comparable. This was a problem in ACT, NSW, NT, SA and TAS. In an attempt to mitigate the above two issues, artificial layers were created for NSW and SA, by cutting present native vegetation (i.e. MVG numbers 1 to 23) into the Carnahan pre-1750 data for these areas. This assumes no change in vegetation type - just whether the type remains (i.e. hasn’t been cleared). For ACT, an artificial layer was created by cutting native vegetation (i.e. MVGs 1 to 23 and 27 (rocks or bare ground)) into the supplied pre-1750 layer. For TAS, the cleared areas in the present vegetation map were filled with the NVIS Stage 1, Version 2 data that has the older detailed typing. This approach was considered acceptable for analysis at the aggregated (MVG) level. The vegetation typing in Victoria has not yet been reconciled with forestry datasets for that State, so the estimates of some vegetation types (e.g. tall open forest) may be subject to change in the future. The scale of input mapping is generally good, as mentioned in the previous section, but exceptions include: o NSW present vegetation – 1:1M mapping in the north west; o NSW pre-1750 – large areas of 1:5M mapping; o NT (both themes) – large areas of 1:1M mapping; o SA present vegetation – 1:2M gap-filling layer; o SA pre-1750 vegetation – large areas of 1:5M mapping; o WA – pre-1750 vegetation – large areas of 1:250K mapping in the Intensive Landuse Zone. The NVIS coastline is generally good, except in the artificially-created pre1750 data for SA and NSW. This may create errors in comparing coastal vegetation types. Limitations of IBRA Version 6.1 This version of IBRA contains the Geoscience Australia1:100,000 coastline and State borders of Australia. This is widely used in ERIN for analytical convenience, but it does not always line up with coastlines in the NVIS dataset. This may create further errors in comparing coastal vegetation types. Also, several State/Territory borders (e.g. VIC/SA) are of questionable accuracy in the dataset. The data are assumed to be correct as supplied by data custodians. 3 National Vegetation Information System Limitations of CAPAD The currency of CAPAD data provided by all jurisdictions meets the agreed date specifications of between July 2003 to June 2004. Protected areas gazetted or altered since June 2004 are therefore not reported as part of this analysis. Only those protected areas meeting the IUCN criteria of a protected area with spatial data and attribution compliant with agreed CAPAD standards have been included in this version of CAPAD. The data are assumed to be correct as supplied by data custodians. Methods Data Preparation The following is a brief outline of the methods used to prepare the data for analysis. The NVIS spatial data began as patches (like a jig-saw puzzle) of detailed vector data across each State and Territory (Fig 1). Each NVIS vegetation description was assigned a Major Vegetation Group by Bruce Cummings in the ERIN NVIS Team in consultation with State/Territory custodians. These codes were brought into the spatial environment as a lookup table for each State and Territory. These lookup tables were joined to each spatial “patch” dataset and the result exported with minimal attribution. Each of these spatial patches was then converted into a raster dataset of MVG. Raster data was at 0.00025 degrees, roughly 25m resolution. This was mostly beyond the specification of NVIS, but considered necessary to pick up remnant vegetation in many parts of Australia. The raster patches were merged into Statewide datasets. These were used for mapping (e.g. Maps 1 & 2) and for subsequent processing with IBRA. Statewide raster datasets were also created for IBRA regions with the same cell size and alignment. A national raster dataset was also created for CAPAD with the same cell size and alignment. Each NVIS theme (pre-1750 or present vegetation) was then combined with IBRA to give the unique combinations of MVG times IBRA region. This combined dataset was used in the first analysis and also combined further with CAPAD reserves for use in the second analysis. Analysis of MVG Changes The combined layers (with MVG x IBRA) were analysed by Zonal Statistics as Table in ArcGIS 9.0 and the results exported to Excel. Statewide comparisons were conducted in a separate spreadsheets for each state. All MVGs in the pre-1750 themes were totalled for each jurisdiction and the results checked against published area statistics (GA, 2005). The raw data was also loaded into a single spreadsheet to enable consolidation of statistics for IBRA regions occurring across borders. 4 National Vegetation Information System Pre-1750 area estimates were used as the basis for “looking up”, in Excel, the corresponding extant area for that type in that IBRA region. A number of summary tables and charts were prepared, as were some selected views of the results. Analysis of CAPAD The combined layers (with MVG x IBRA x CAPAD) were analysed by Zonal Statistics as Table in ArcGIS 9.0 and the results exported to Oracle. SQL queries were developed to generate summary statistics for MVG and overall reservation by the continent, State and IBRA region. A number of summary tables and charts were prepared, as were some selected views of the results. Presentation The 23 MVGs representing native vegetation have been reported, whilst the non-native and non-vegetative MVGs have not been reported. The results of the two analyses have been consolidated, where feasible for the sake of brevity. Maps included throughout the text are intended for display at A4 and/or A3 size and are available on request from the ERIN NVIS Team. Results Continental Maps The NVIS dataset is displayed as 2 maps of the Australian continent indicating: Pre-1750 Major Vegetation Groups (Map 1) Present (2001-04) MVGs (Map 2) Continental Summaries The area of pre-1750 MVGs is compared with their present area and reservation level across the continent in a summary histogram (Fig 2).

This includes the remaining present vegetation area as a percentage of the area of pre1750 native vegetation. These percentages have been classified into 5 simple classes to map the result (Fig 4). Figure 4: Percentage of remaining native vegetation in each IBRA region. Fig 5 shows a map of each IBRA with the number of MVGs occurring there. This is a gross measure of ecosystem diversity for each IBRA region. 9 National Vegetation Information System Fig. 5: Total number of native MVGs per IBRA region.

Victoria, Queensland and Tasmania have achieved Statewide NVIS coverage at a detailed level, to add to Northern Territory and Western Australia in NLWRA (2001). All NVIS vegetation descriptions, except those for NSW, comply with the NVIS standards (ESCAVI, 2003). The NVIS partners have conducted workshops to ensure the improved alignment of vegetation types across borders. The remaining anomalies (Maps 1 and 2) arise from fundamental differences in source datasets – particularly the scales of mapping and differences in the recognition of vegetation types. Cartographic anomalies remain in the non-vegetated and non-native areas, such as salt lakes, where standardisation was beyond the scope of this project. The continental data summaries update the respective tables and figures of NLWRA (2001). The national and statewide summaries are qualitatively similar, reflecting the natural distribution of vegetation types and the historic impacts of human usage – particularly clearing for agriculture. Quantitative changes from NLWRA (2001) are more likely to be a result of re-classification within the source datasets and subsequent description in the NVIS attributes, rather than true vegetation change. This is clearly the case in Victoria. However, the comparison between pre-1750 vegetation and present vegetation in this version of NVIS is considered to provide a better estimate of vegetation change than in NLWRA (2001). The broad picture of vegetation loss is well known (NLWRA, 2001; EA/NLWRA, 2001). The analysis of native vegetation remaining by IBRA region (Appendix B and Fig 4) summarise the loss of native vegetation. Maximum native vegetation loss is in the Victorian Volcanic Plain and Avon Wheatbelt, WA. The remaining figures illustrate some of the derived summaries than can be extracted from the detailed spreadsheets provided. The results have not been discussed in detail. Major areas of MVG diversity (Fig. 5) are in the Eastern States. This is expected with MVGs having a strong structural component. The complexity in the lower MurrayDarling Basin cannot be readily explained. Standardisation of the number of MVGs per unit area may give an improved picture. The number of MVGs with remaining areas <10% and <30% (Figs 6 & 7) are a gross estimate of threatened ecosystems. The same thresholds applied to particular MVGs (Figs 8-11) reveal familiar patterns. For example, rainforests in southern Queensland, northern NSW and southern Victoria appear most depleted. Eucalyptus Woodland, Acacia Forest and Woodland and Mallee Woodland and Shrubland MVGs have been heavily cleared in the wheatbelt areas.The high figures for coastal and tableland NSW require further investigation at the detailed level, since the result may be an artefact arising from inadequate data or errors in the analysis. 15 National Vegetation Information System References Environment Australia and National Land and Water Resources Audit (EA/NLWRA) (2001).
