Site details
Site description: Isla Mocha National Reserve occurs on Isla Mocha, a small Chilean island approximately 48 km2 in area, located west of the coast of Arauco Province. The reserve provides habitat for the pudú and for a variety of birds, including the pink-footed shearwater. Typical vegetation includes Olivillo, Chilean Myrtle, Valdivia's Patagua, Chilean Laurel, Tepa and Winter's Bark. A small chain of mountains runs north-south.
Rationale for qualifying as KBA: This site contains the entire known population of the critically endangered amphibian Eupsophus insularis and the Pacific degu (Octodon pacificus). It also meets A1a, B1, and D1a for the Pink-footed Shearwater (Ardenna creatopus). Alliance for Zero Extinction (2022): site confirmed as an AZE site during the AZE project (2018-2022). Taxonomy, nomenclature and Red List category follow the IUCN 2021 Red List.
Additional biodiversity: Patagioenas araucana Ardenna creatopus Pteroptochos tarnii Scelorchilus rubecula Eugralla paradoxa Octodon pacificus
Other site values: Site is managed by the Corporación Nacional Forestal (CONAF) with an active management plan in place.
