Expected survival of listed and threatened species and ecological communities: Data packages for the Biodiversity Indicator Program, first assessment

This data collection contains the tabular data and R scripts used to generate three biodiversity indicators for the NSW biodiversity baseline 2017: a) Expected survival of listed threatened species; b) Expected existence of listed threatened ecological communities; and c) Expected survival of phylogenetic diversity of listed threatened species (for mammals, birds and amphibians). The indicators are an application of the ‘expected diversity’ framework. Expected Diversity, as a measure of biodiversity status and trend, was applied to the lists of threatened species and ecological communities as determined by the NSW Threatened Species Scientific Committee (TSS-C) between 1995 and 2017 (prior to 25th August 2017m the date of commencement of the Biodiversity Conservation Act 2016. The data and scripts provided in the data collection will allow the pre-commencement analyses of these indicators to be re-run. The method as applied in the scripts is designed to allow future iterations of the indicators to be run on an annual basis, if desired. Changes to taxonomy, future determinations of the NSW TSS-C, and future reporting on the effectiveness of threatened species management will require revision of the underlying data used in the indicators. Guidelines on how to re-run the analyses using the scripts and adapt the data package for future iterations of the indicators is provided in the implementation report (Nipperess DA, Faith DP, Auld TD, Brazill-Boast J, Williams KJ & King D (2020) Expected survival of listed and threatened species and ecological communities. Biodiversity Indicator Program Implementation Report, Department of Planning Industry and Environment NSW, Sydney, Australia.), and relevant guidelines extracted from the report are attached with this data package.
