Species of National Environmental Significance
About the database
The Species of National Environmental Significance Database contains maps and data which provide general information on the distribution of species related to the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act).
Southern Corroborree Frog
In order to provide important information to the community about Australia’s protected species, and in line with the Government’s policy of open data access, the map and data products for threatened and migratory species in this database have been generalised and developed for public release.
New map and data products
The generalised distribution maps held in the database are based on ecological data and research information documents such as species observation records and national-scale environment data.
Department of the Environment spatial ecologists use modelling software to map the known and predicted distribution of listed species, including areas of potential habitat. These maps are indicative rather than definitive, and they are a starting point for further investigation rather than the outcome of a comprehensive scientific assessment.
Version 2 is now available, updating the full set of species maps and now including both vector and raster format gridded data.
Species of National Environmental Significance map summary
The maps contained in this database are summary versions which have been generalised to ensure locations of species sensitive to illegal collection and disturbance are not made publicly available. The maps are made up of GIS layers containing species distributions generalised to a 10 km grid resolution (0.1°).
It is aimed at addressing concerns regarding the release of detailed data while providing a national distribution map of species that can be made broadly available. It is however, not suitable for either local scale analysis or area-based calculations.
The GIS data are coded as –‘Species or species habitat likely to occur’ (pixel value 2) and ‘Species or species habitat may occur’ (pixel value 1). The ‘known to occur’ category is not available in the summary product and has been included in the ‘Likely to occur’ category.
The products are suited to a range of applications and can be used at various scales in a geographic information system.
Additional information is available in the user guide which is also included with each download.

A PNG format contextual map for each species is also provided (see links below). Use the included index spreadsheet in CSV format to identify the map number (taxon identifier) of individual species within the appropriate zip file. The maps are grouped by type and in the case of flora, alphabetically by the first three letters of the scientific name to reduce download size. Note the full set of zipped maps total approximately 1 GB of data.
PLEASE NOTE: These are very large files and may take some time to download. All Version 1 maps have been superseded by version 2 available below.
