NSW NVACE |
Abstract |
The NSW Native Vegetation Area Clearing Estimate (NVACE) is a statewide spatial vector layer estimating the presence and absence of native vegetation at 2020. The NVACE does not discriminate different types of native vegetation. The dataset was first published by NSW Department Planning and Environment (DPE) in 2023 and will be updated intermittently. The NVACE uses best available primary and supplementary datasets to identify areas where native woody and non-woody vegetation occurs. Due to datasets being of different ages and resolution, errors of commission and omission may be included. Primary published datasets used in the creation of NVACE Version 1 include: The NVACE is refined using a combination of datasets to remove known areas of clearing, for example, Statewide Landcover and Tree Survey (SLATS) data for woody vegetation and non woody vegetation change clearing events from Non-Woody Landcover Disturbance Program (NWD). The Geoscape Surface Cover raster is used to refine native vegetation in urban areas. Components are used to remove roads and swimming pools and add increased resolution tree canopies. Land identified as Category 1 exempt under the amended Local Land Services act 2013 has been removed from NVACE as per the Biodiversity Conservation Act 2016. Small polygons resulting from editing the NVACE are removed as artefacts. A more detailed description of the methodology is published and provided on the DPE website. The NVACE dataset has been developed by DPE to provide guidance on whether a development exceeds the Area Clearing Threshold for entry into the Biodiversity Offsets Scheme (BOS), as guided by Biodiversity Conservation Regulation 2017 s7.2. Together with the Biodiversity Values Map, the NVACE forms the basis for determining whether a local development (Part 4 NSW EP&A Act) should be assessed for inclusion in the Biodiversity Offsets Scheme. A development which is required to be assessed for clearing of native vegetation in the Biodiversity Offsets Scheme may then potentially require biodiversity offsets against any losses undertaken as part of the development. The dataset is primarily available to be displayed at a property scale when preparing a Biodiversity Map and Threshold (BMAT) report but may be provided on application to users in a spatial data format.

Lineage |
The NSW Native Vegetation Area Clearing Estimate (NVACE) is a polygon feature class stored in a single ESRI geodatabase. If NVACE polygons are mapped in an area, then native vegetation is determined to be present. The NVACE has been constructed to provide an indicative estimate of the area of native vegetation with potential to be cleared in a property development, which guides Councils and proponents in determining whether a local development triggers the Biodiversity Offsets Scheme (BOS). The NVACE is developed and built upon the NSW Native Vegetation Extent (NVE) 5m raster and NSW land use 2017, sourcing the most temporal and high-resolution data available to maximise the dataset's currency and accuracy in areas where development is most likely to occur. All the source datasets and mapping processes were completed in ArcGIS environment. The NVACE uses MGA Cartesian coordinate system, with input data being reprojected as necessary. The mapping process is split into the following two stages.
The NVE Raster is spatially combined with NSW Landuse 2017 v1.3 (subsequently published as version 1.4, referred to in this report as Landuse) and the State Vegetation Type Grassland Plant Community Types to create an interim native vegetation layer. Where the layers intersect with conflicting native/non-native attributes, the Landuse attribute is retained due to its currency and resolution. The interim native vegetation layer is refined to remove known non-native vegetation using the Geoscape Australia’s Buildings layer (used to identify building developments), a State Forest Plantation layer used to remove non-native forest and a NSW Hydro Area layer which removes known non-native water infrastructure. This creates the Native Vegetation Indicator layer (Stage 1).
The Native Vegetation Indicator (NVI) Stage 1 is refined using a combination of datasets used to remove known areas of clearing, for example, Statewide Landcover and Tree Survey (SLATS) data for woody vegetation and non woody vegetation change clearing events from Non-Woody Landcover Disturbance Program. The Geoscape Surface Cover raster is used to refine native vegetation in urban areas. Components are used to remove roads and swimming pools and add increased resolution tree canopies. Small polygons resulting from editing the NVI are removed as artefacts.
Lands mapped in the Transitional Native Vegetation Regulatory Map as draft Category 1 – exempt land (NVR Map Draft Category 1) are excluded from the Biodiversity Offsets Scheme and are removed from the final NVACE layer. The individual mapping tiles are merged into a single binary statewide geodatabase file. The NVACE layer is a binary layer depicting the presence of native vegetation. If NVACE polygons are present in an area, it is highly likely native vegetation is present. The resolution of NVACE is inherited from the datasets used to build the layer. Although the minimum resolution of the input datasets is 2 × 2 m (Geoscape Surface Cover raster), it is only applied to urban and peri-urban area within Geoscape data coverage. The majority of the NVACE has a resolution of 5 × 5 m. The detailed mapping method is published and provided by DPE. |
