Vegetation extent

A variety of vegetation extent product types are now available. This catalogue includes the best contemporary products representing the extent or change in extent in woody, non-woody or native vegetation; as well as older (historic) products that were used previously in significant reporting or regulation processes.

Woody vegetation extent

Dataset: Landsat woody extent and foliage projective cover (FPC) Ver 2.1 (25m) 2008

Description: The best available Landsat representation of woody vegetation extent in NSW at 2008.

Dataset: Landsat woody change data (25m) for 1988-2010

Description: Raster (grid) layers showing areas and type of woody vegetation change based on the analysis of multi-date Landsat imagery. Data are available as 572 scenes (13 biannual periods each with 44 Landsat scenes) covering NSW. Used to calculate annualised woody vegetation change rates used in the 2010 NSW Annual Report on Native Vegetation. A user-friendly vector geodatabase, NSW SLATS LANDSAT Woody Change Vector Database 1988-2010, has been derived from these grid layers and can be accessessed directly from the OEH data download site.

DatasetNSW Woody Vegetation Extent 2011

Description: 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 contiguous forest at a 5m resolution. This latest map of woody vegetation extent for NSW is the highest detailed to date. It shows the location, extent, and density of foliage cover for stands of woody vegetation in NSW for the year 2011. The resolution is good enough to identify small features such as trees in paddocks and scattered woodlands through to the largest expanse of forest in the State.

Dataset: NSW Woody Vegetation Extent & FPC 2011

The NSW Woody Vegetation Extent & FPC 2011 is a state-wide classification of woody vegetation and Foliage Projection Cover (FPC) derived from multitemporal 5m SPOT-5 satellite imagery. The product broadly identifies isolated tree crowns as well as contiguous forest at a 5m resolution and each woody pixel also contains a measure of FPC. FPC is the fraction of the ground that is obscured by green leaf, and is a measure of density.

Dataset: Rectified and radiometrically corrected Landsat imagery. 1988–2010

Description: These are the pre-processed Landsat images prepared by the OEH Statewide Satellite Landscape Monitoring Program and are used to generate all other Landsat products. They are rectified to a map projection and adjusted for the effects of the atmosphere, sun angle, view angle and topography. They could be used to generate remote sensing other products for other applications.

Non-woody vegetation extent

Dataset: NSW Native Vegetation Extent. MODIS/FPC. 2008

Description: This is a prototype product which was prepared for a Natural Resource Advisory Council (NRAC) Grassland Project. It includes a classification of native non-woody vegetation, including candidate native grassland (derived from MODIS time series), which has been combined with native woody extent, derived from an early version of the Landsat Foliage Projective Cover (FPC) data. This product has not been validated, but may be useful for landscape connectivity studies and for indications of potential native grassland distribution.

Native vegetation management (NVM) benefits

A series of spatial analyses were undertaken to predict where native vegetation management will contribute the highest benefit to terrestrial biodiversity at a statewide scale. The analyses focus on improving the condition, extent and connectivity of vegetation formations in NSW. They were designed to inform investment in native vegetation management in NSW through mechanisms such as the catchment action plan upgrades, public land management planning, local government investment and private land conservation funding and investment.

NVM manage benefits

Dataset: NVM manage benefits

Description: 'Manage' benefits identify areas of existing native vegetation in good condition where emphasis on management would be on maintaining this high condition. These benefits were developed through the application of the terrestrial Biodiversity Forecasting Tool (BFT).

NVM improve benefits

Dataset: NVM improve benefits

Description: 'Improve' benefits also relate to areas of existing native vegetation, and while these are generally the best examples of more heavily altered vegetation types, they nonetheless require some form of active management to improve their condition. These benefits were developed through application of the terrestrial Biodiversity Forecasting Tool (BFT).

NVM landscape value (consolidate) benefits

Dataset: NVM landscape value (consolidate) benefits

Description: 'Consolidate' benefits highlight areas where conservation of existing vegetation, condition improvement of degraded vegetation, or rehabilitation of cleared areas are most likely to contribute to maintaining and enhancing connectivity across a region. Consolidate benefits were developed using landscape values analysis techniques.

NVM  revegetate benefits

Dataset: NVM revegetate benefits

Description: 'Revegetate' benefits highlight cleared areas where replanting or natural regeneration of species that previously occurred on the site would return the highest benefit. The aim is to increase the area of vegetation types which have been most heavily cleared. A large proportion of these areas occur on productive agricultural lands. As such, only a small proportion will be revegetated, particularly where they contribute to farm productivity. These benefits were developed through application of the terrestrial Biodiversity Forecasting Tool (BFT).
