Alliance for Zero Extinction

The Alliance for Zero Extinction (AZE) is a joint initiative of biodiversity conservation organizations to prevent species extinction. AZE encompasses over 115 partners, ranging from local organizations focused on conserving single sites to large international NGOs with strong experience in multinational conservation projects.

AZE curbs extinction by identifying and safeguarding key sites, defined as the last remaining refuges of one or more Endangered or Critically Endangered species. The Alliance uses the following criteria to determine priority sites:

1. Endangerment: An AZE site must contain at least one Endangered (EN) or Critically Endangered (CR) species, as determined by the IUCN Red List.

2. Irreplaceability: An AZE site should only be designated if it is the sole area where an EN or CR species occurs, or contains the overwhelmingly significant known resident population of the EN or CR species, or contains the overwhelmingly significant known population for one life history segment (e.g., breeding or wintering) of the EN or CR species.

3. Discreteness: The area must have a definable boundary within which the character of habitats, biological communities, and/or management issues have more in common with each other than they do with those in adjacent areas.

With 853 AZE sites across the globe, the Alliance is protecting the world's most threatened species and helping to preserve biodiversity. AZE will work with Initiative 20x20 partners to protect and restore biodiverse forests throughout Latin America.
