There is a clear need to refocus the way we prioritize conservation actions at a global scale to incorporate human systems. Anthromes have been suggested as one tool for integrating anthropogenic effects on ecosystems, but there have been limited spatially explicit applications of anthromes to biodiversity patterns at a global scale. To address this gap we used global data sets of anthromes, terrestrial vertebrate richness, and number of threatened vertebrate species. We ranked anthrome by richess at a global scale, temperate and tropical extents, and within major biogeographic realms. We also tested for correlations between overall richness and count of threatened species. Wildlands had the lowest richness. Seminatural residential woodlands had the greatest median richness, followed by rice and pastoral villages The number of threatened birds was greatest in villages and the greatest number of threatened mammals was in remote semi-natural woodlands anthromes. The relationship between threatened and total richness was linear for all taxa. Regional heterogeneity was clear across biogeographic realms. Human modified ecosystems provide opportunities for conservation and global and regional ranking within anthromes helps identify priorities that can complement biome and ecoregion based prioritization. Currently, much of conservation research and prioritization is in wildlands or perceived natural landscapes, however this data shows a clear need to focus conservation efforts on seminatural and residential lands. These data would be helpful for global conservation organizations as an updated framework that can be used to prioritize global resource allocation while considering both ecological and social systems.
