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).

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.

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.

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.

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.



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.

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). The corresponding table of areas
is also shown (Table 2), with the percentage remaining and reservation of each MVG
listed.
Statewide Summaries
Statewide summaries of native MVGs are listed in Appendix A. The native Major
Vegetation Groups occurring in each State and Territory are listed in order of
decreasing area of present vegetation. A percentage of remaining area of each MVG is
also listed, as is the percentage (of present MVG area) reserved.

Analyses by IBRA Regions
The total native vegetation in each IBRA region has been collated in Appendix B.
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.

Discussion
The continental maps are an improvement on the previous versions of NVIS as more
of the data are sourced from detailed vegetation surveys. 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.
