This data represents the indicative known and predicted distributions of threatened ecological communities, population and species. These data are a snapshot of data held and maintained in the Bionet – Threatened Species Profiles. The data were extracted mid-November 2013.

The base geometry is derived from a GIS intersection of a NSW Catchment management Authority Layer and IBRA Subregions layer (Interim Bio-regionalisation of Australia). For each NSW (TSC Act) and Cwth (EPBC Act) listed entity the "known" or "predicted" occurrence of each entity is attributed against the base polygon layer based. "Prediction" of occurrence should be treated as having a low confidence.

Attribution of "Known" occurrence is based on the existence of at lease one valid observation record for that polygon (locality). Validation of TS records is completed by nominated Threatened Species experts within NSW OEH (Office of Environment and Heritage). The Assignment is based on expert knowledge and is generally not assisted by distribution modelling approaches.

These data are rendered live from BioNet database to the Office of Environment and Heritage Threatened Species Web site (http://www.environment.nsw.gov.au/threatenedSpeciesApp/). See the following link for an example of a profile with indicative distribution map: http://www.environment.nsw.gov.au/threatenedspeciesapp/profile.aspx?id=10616
