A new paper, “Methodology for identifying the potential Alliance for Zero Extinction (AZE) tree species on a global scale”, by Katharine Davies, Thomas Starnes, and Malin Rivers, has now been published in Conservation Science and Practice, a journal of the Society of Conservation Biology.

Key Biodiversity Areas (KBAs) apply an international standard for identifying sites of significance for the global persistence of biodiversity and are highly important across many areas of decision-making. Alliance for Zero Extinction (AZE) sites, a subset of KBAs, contain ≥95% of the population of highly threatened species. Previously, only a small number of trees have been identified using the AZE criteria. In this new paper, a methodology has been developed to utilize data from the IUCN Red List to identify potential AZE species for trees. This methodology identified 2,909 tree species as potential AZE species across the world. This analysis serves as a prioritization mechanism for identifying species in urgent need of conservation action to prevent extinctions, and can feed into national KBA identification efforts.

The map shows the number of IUCN countries of potential Alliance for Zero Extinction (AZE) tree species. Based on the IUCN Red List assessed species with public range maps.
