Global dynamic maps of terrestrial Area-of-Habitat (AOH)

This dataset provides spatially explicit biodiversity data at an approximate 10 km resolution for four terrestrial vertebrate groups: mammals, amphibians, reptiles, and birds. The dataset includes five time slices—1990, 2020, 2030, 2050, and 2100—allowing the assessment of biodiversity patterns and their long-term changes from past to future. It contains four ecoregion-level indicators: species richness, threatened species richness, species endemism, and AOH density. These indicators were derived from species-level environmental suitability mapping that integrates both climatic conditions and habitat constraints, thereby providing a consistent basis for representing species distributions across time. By combining taxonomic breadth, long-term temporal coverage, and standardized ecoregion-level metrics, the dataset supports analyses of global biodiversity patterns, conservation priorities, and projected future changes under environmental change.
