Global patterns of terrestrial vertebrate diversity and conservation

Abstract

Significance: Identifying priority areas for biodiversity is essential for directing conservation resources. We mapped global priority areas using the latest data on mammals, amphibians, and birds at a scale 100 times finer than previous assessments. Priority areas have a higher—but still insufficient—rate of protection than the global average. We identify several important areas currently ignored by biodiversity hotspots, the current leading priority map. As the window of opportunity for expanding the global protected area network begins to close, identifying priorities at a scale practical for local action ensures our findings will help protect biodiversity most effectively.
