Various vegetation Extent and Nativeness products, that include: the delineation by woody and non-woody; and maps of the uncertainty associated with assignment of extent and nativeness. The primary product is a NSW Native Vegetation Extent layer prepared for the National Land and Water Resources Audit 2008. This represents native vegetation extent at 2006. A number of other useful intermediate products are also available. Full report is available from http://maps.environment.nsw.gov.au ; ; VEGETATION EXTENT was derived from interim Foliage Projected Cover (FPC) data (FPC 00,02,04,06) prepared by the DECC's Woody Vegetation Change Detection Program in early 2008. FPC is generated from Statewide Landcover And Trees Study (SLATS) methodology, developed in Queensland by Qld Dept of Natural Resources and recently applied in NSW. The SLATS program applies a series of algorithms on Landsat TM data to produce FPC values ranging from 0-100 percent. A threshold (or thresholds) are applied to the FPC data to separate woody from non-woody vegetation. NATIVENESS was derived from interim NSW Land-use Mapping data (Emery et. al), and then used to ascertain whether vegetation may be native or non-native.; ; CAVEAT:Vegetation extent and nativeness layers generated for this project are interim in nature and are subject to ongoing refinement. While these products represent the best available estimate of vegetation extent and nativeness at this time they will be improved overtime and hence are not suitable for accurate reporting of vegetation change

A dataset of Native Vegetation Extent for NSW, prepared for the NRAC grassland mapping project NRP009 PART B. Raster grid, NSWVEGEXT08, with a land cover classification representing an experimental native non-woody and native woody vegetation extent. THIS DATASET IS NOT SUITABLE FOR USE IN THE FORMAL REPORTING OF NATIVE VEGETATION EXTENT. It is a composite product, synthesising inputs from a MODIS time series data cube (2000-2008), an fpc thresholded (SLATS) woody mask, and OEH's NSW Land Use vector layer (for woody nativeness).

Data represents NSW native vegetation extent, compiled from various vegetation maps using method outlined in (Keith and Simpson 2006). Data is also known as Keith and Simpson (2006) Version 002. Includes 4 layers i) woody native veg extent (natwdy_002), ii) non-woody native veg extent (rgrass002), and iii) secondary grassland extent (sgrass002). natwdy002 and rgrass002 are combined to create total NSW native veg extent (extveg_002). Data was developed for use in the July 2006 Biometric tool update, and specifically the update of the Over-Cleared Landscapes database, which underpins the NSW Property Vegetation Planning (PVP) process. Supersedes Keith (2004) and Pressey et al. (2000). Pressey et al. (2000) was the native veg extent product used to calculate native veg cover values for the Over-Cleared Landscapes Database prior to July 2006. (also see (Keith and Simpson,in press)

"Reconstructed" vegetation of the NSW Riverina. The area includes the NSW portion of the Riverina Bioregion as defined by the Interim Biogeographic Regionalisation of Australia (Thackway and Cresswell 1995) and additional areas outside the Riverina bioregion but included in the Western Riverina Regional Vegetation Management Area (see Figure 1).; ; VIS_ID 973

The NSW 5m Woody Extent is a state-wide binary classification of woody vegetation derived from multitemporal 5m SPOT-5 satellite imagery. The product broadly identifies isolated tree crowns as well as contigous forest at a 5m resolution. This latest map of woody vegetation extent for NSW is the highest detailed to date. It shows the location and extent of woody vegetation in NSW for the year 2011. It can be used to identify small features such as paddock trees and trees in scattered woodlands, to the largest expanses of forest in the state. It is intended for use in non-urban environments and its accuracy for urban environments has not been assessed. The dataset is also used as a spatial constraint for a seamless map of woody foliage projection cover (FPC). FPC is the fraction of the ground that is obscured by green leaf, and is a measure of density. The FPC dataset is delivered as a separate map to the woody extent (although it is constrained by it), and it can also be requested from the OEH data broker. The woody extent product was derived from user-driven thresholds on an index of woody probability. The probability was calculated from a binomial logistic regression model on multi-temporal data. The model utilsed the statistics from SPOT-5 imagery over 2008-2012 and referenced over 26000 training points. Comprehensive manual corrections were also performed throughout 2013-2014 at a scale of 1:15000. The dataset is provided in 8-bit raster format with the following attributes values: 1 = Woody 0 = Non-Woody 255 = null (either outside the NSW boundary or a perennial water feature) Overall state accuracy is recorded at 90.1% when compared to Lidar datasets (see lineage for more information), and 88% when compared to 6670 visually derived validation points. Although this dataset has undergone extensive manual corrections, the accuracy for specific regions may vary considerably. http://www.auscover.org.au/xwiki/bin/view/Product+pages/nsw+5m+woody+extent+and+fpc

The 2022 NSW Forest extent layer was created by the NSW DPIRD Forest Science team applying spatio-temporal analysis of the 2017-2022 National Forest and sparse woody vegetation data (Version 7.0 - 2022 Release) (Department of Climate Change, Energy, the Environment, and Water's). The data is available on data.gov.au. The dataset was further analysed and masked to exclude non-forest areas and create a forest extent layer with a 20 percent canopy cover for the NSW UTM Zones 55 & 56. The mask layer includes various datasets such as NSW Land use 2017, State Vegetation Type map (SVTM), Land Zoning, Water body, etc. The DPIRD Plantation unit's Authorised plantation layer (current as Aug 2024) was used to characterise forest types, i.e. Native forest and Plantation.

The purpose of this layer is to help discriminate native tree cover and woodlands from other terrain elements. The NSW Native Vegetation Extent 5m Raster v1.4 was developed under the State Vegetation Type Map program (SVTM) and presents a single surface raster that combines the best available information on native vegetation extent for NSW. The surface differentiates tree cover from candidate native grasslands, water, forestry plantations and a woodland matrix from non-native areas. The surface is built on the 2011 5m NSW Woody Vegetation Extent (Fisher et al., 2016), with updates up to 2018 (Fisher et al., 2017), with the addition of candidate native grasslands, woodlands and wetlands from the visual interpretation of high-resolution imagery (OEH, 2017). The NSW Native Vegetation Extent 5m Raster v1.4 is an integration of five existing datasets which map candidate native vegetation and water bodies for NSW. The sourcing rules from each dataset are documented in the metadata statement at the link below.
