Data from: Analysing biodiversity and conservation knowledge products to support regional environmental assessments

Two processes for regional environmental assessment are currently
underway: the Global Environment Outlook (GEO) and Intergovernmental
Platform on Biodiversity and Ecosystem Services (IPBES). Both face
constraints of data, time, capacity, and resources. To support these
assessments, we disaggregate three global knowledge products according to
their regions and subregions. These products are: The IUCN Red List of
Threatened Species, Key Biodiversity Areas (specifically Important Bird
& Biodiversity Areas [IBAs], and Alliance for Zero Extinction
[AZE] sites), and Protected Planet. We present fourteen Data citations:
numbers of species occurring and percentages threatened; numbers of
endemics and percentages threatened; downscaled Red List Indices for
mammals, birds, and amphibians; numbers, mean sizes, and percentage
coverages of IBAs and AZE sites; percentage coverage of land and sea by
protected areas; and trends in percentages of IBAs and AZE sites wholly
covered by protected areas. These data will inform the
regional/subregional assessment chapters on the status of biodiversity,
drivers of its decline, and institutional responses, and greatly
facilitate comparability and consistency between the different
regional/subregional assessments.
