Description Aggregated Australian species occurrence data from 1900 to the present using a suite of facets of most importance for environmental assessments. 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/).

Data from these infrastructures and other sources have been organised here as a national public-access dataset.

This dataset serves as a standardised snapshot of Australian biodiversity occurrence data from which many indicator datasets can more readily be derived (see Has Derivation entries below).

The primary asset is AggregatedData_AustralianSpeciesOccurrences_1.1.2023-06-13.csv. This contains all faceted data records for the period and supported facets related to time, space, taxonomy and conservation significance.

Six derived assets (SummaryData-ProtectionStatusAustralianMarineSpeciesOccurrences-1.1.2023-06-13.csv, SummaryData-ProtectionStatusAustralianTerrestrialSpeciesOccurrences-1.1.2023-06-13.csv, SummaryData-IntroducedSpeciesOccurrencesByMarineEcoregion-1.1.2023-06-13.csv, SummaryData-IntroducedSpeciesOccurrencesByTerrestrialEcoregion-1.1.2023-06-13.csv, SummaryData-ThreatenedSpeciesOccurrencesByMarineEcoregion-1.1.2023-06-13.csv, SummaryData-ThreatenedSpeciesOccurrencesByTerrestrialEcoregion-1.1.2023-06-13.csv) demonstrate uses supported by the faceted data. Each is a pivot of the aggregated dataset.

The data-sources.csv file includes information on the source datasets within the Atlas of Living Australia that contributed to this asset. README.txt documents the columns in each data file.

Grouping records from this dataset supports comparisons between the number of occurrence records for different regions and/or time periods and/or categories of species and occurrence data. Grouped counts of this kind may serve as useful indications of variation and change across the dimensions compared. Note however that such counts may not accurately reflect real differences in biodiversity. It is important to consider confounding factors (particularly variations in recording effort over time). Grouping all records by a single facet (e.g. IBRA region) may help to expose such factors.

These data are versioned at 12-month intervals. Previous versions will be linked below under Previous Version. The latest version can always be accessed at https://ecoassets.org.au/data/aggregated-data-australian-species-occurrences/.

Notes

GRIIS 1.6 includes a number of vertebrate species listed because some individuals have been translocated or (re-)introduced beyond their remaining ranges for conservation purposes. It is unhelpful for the current analysis to treat these as introduced species. These species were removed from the version of the GRIIS list used in this analysis. In future versions of GRIIS, these species will be documented as native species that have been translocated/reintroduced.
