The International Union for Conservation of Nature (IUCN) Red List of Threatened Species is the most comprehensive inventory of the conservation status of global biodiversity. With a strong scientific base, the IUCN Red List uses a set of criteria to evaluate the extinction risk of species and define a threat category for animal, fungi, and plant species. It is a powerful tool that can inform priority actions for biodiversity conservation and policy change.
The IUCN aims to review species’ threat category periodically, a process that is done through a peer reviewed process and coordinated by the IUCN Species Survival Commission Specialist Groups. This process is led by Red List Authorities responsible for a group of species and, in the case of amphibians, it is led by the Amphibian Specialist Group (ASG).
To date, more than 120,000 species have been assessed by the IUCN. Among vertebrates, amphibian is the most threatened group and 41% of species are threatened with extinction.
Through a global network of experts and partner organizations, the ASG compiles the up-to-date data for every known amphibian species to complete a Global Amphibian Assessment. The first comprehensive study of the conservation status of amphibian species was published in 2004 and the second Global Amphibian Assessment is underway. The goal is to update the 2004 assessments and complete the first-time assessments for thousands of newly described amphibian species.
The known amphibian fauna of Brazil comprises of 1,136 species, the vast majority are anurans, followed by caecilians, and salamanders (click here for a complete Brazilian species list). The IUCN Red List assessment review for amphibians in Brazil is therefore a challenging task but we will be working hard and in collaboration with experts to complete this mission by 2020.
To complete the second Global Amphibian Assessment, the ASG is working with scientists and conservationists around the world. In Brazil, amphibian species reviews and assessments are being coordinated by a Brazilian NGO, Instituto Boitatá. Our amphibian team at Durrell is collaborating with two major biomes, the Cerrado and the Atlantic Forest (read more about our work in Brazil at Rewild our forest).
At SAFE we collaborate with amphibian conservationists worldwide by working in threatened sites where action is needed the most.
We look forward to sharing updates from Brazil with you!
