Threatened rarity-weighted species richness refined by area of habitat

This dataset provides an indication of how ‘important’ a given area is for amphibians, birds, mammals, reptiles and a representative set of plant taxa whose distribution overlap by aggregating rarity values, a richness value which takes into account the number of species and the size the range of the species (i.e. a measure of endemism). Conservation status data was used to select a subset of threatened species, based on data from the IUCN Red List and the ThreatSearch online database (BGCI 2019). Given that extinction risk data is not available for all species considered in the analyses, users should be aware of the taxonomic bias of the layer.
