Summary of species occurrence data from 1900 to 2020 for Australian marine species organised by IMCRA region and EPBC status. Counts are provided by species and IMCRA region for: The total number of occurrence records within the region, for a given EPBC status and time period The number of distinct species recorded within the region, for a given EPBC status and time period Occurrence records were aggregated and organised by the Atlas of Living Australia (ALA, https://ala.org.au/) and include survey and monitoring data collected and managed by the Integrated Marine Observing System (IMOS, https://imos.org.au/) and the Terrestrial Ecosystem Research Network (TERN, https://tern.org.au/).

__Threatened Species of National Environmental Significance__ This dataset contains information about species of national environmental significance as listed in the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). Data provided includes: - species names and threatened status - indicative occurrence within each state, territory and marine area - links to further information in the [Species Profile and Threats Database](http://www.environment.gov.au/cgi-bin/sprat/public/sprat.pl) (SPRAT). The dataset is updated as the lists of species on schedules of the EPBC Act are amended. There is one row entry for each listed species. Links to other species information sourced from SPRAT can be made using the field containing the listed taxon identification number (ListedId). A description of the fields and methods used to create the data can be found in the explanatory notes resource.

Data provided includes: - ecological community name and threatened status - indicative occurrence within each state and territory - links to further information in the [Species Profile and Threats Database](http://www.environment.gov.au/cgi-bin/sprat/public/sprat.pl) (SPRAT). The dataset is updated as the lists of ecological communities on schedules of the EPBC Act are amended. There is one row entry for each listed ecological community. Links to other ecological community information sourced from SPRAT can be made using the field containing the listed community identification number (ECId). A description of the fields and methods used to create the data can be found in the explanatory notes resource.
