Red Listing in Costa Rica  


Red list assessment keys 

This week I have been taking part in the 2019 IUCN Red List assessment workshop on the amphibians of Costa Rica. This is part of a worldwide effort to assess the status and conservation requirements of all known amphibians. This process is repeated every 10 years to consider all newly described species, and any changes that have occurred that might influence the status of species previously evaluated.

This immense undertaking is the remit of Jennifer Luedtke and Kelsey Neam from the Amphibian Red List Authority – IUCN SSC Amphibian Specialist Group. They have been working their way across the world over the past few years, organising workshops and patiently collecting and streamlining the thoughts and findings of hundreds of world’s top herpetologist. To develop the second Global Amphibian Assessment.

This is vital work, that will play a key role in informing conservation interventions for a number of species previously overlooked. It is also an opportunity to acknowledge where species are recovering, from conservation work or bouncing back after historical loses.


Luis Carrillo from Amphibian Ark has also had a key role in assessing the new findings and proposing projects to enhance conservation outcomes of the red list. We also fed the findings of the workshop into the database for the Alliance for Zero Extinction, helping to prioritise conservation areas to limit the threat of extinction to some of the world’s rarest species.

Bringing together herpetologists and experts from across multiple disciplines, the workshop has hosted over 30 people who have volunteered their time to help deliver key information towards the project. It has been a great opportunity to share experiences and network with people working on the huge diversity of amphibians found in this country, a total of 216 species to date!

It has been a privilege to be involved with this project, and would like to extend my thanks to Yolanda Matamoros and the rest of the staff from Zoológico y Jardín Botánico Nacional Simón Bolívar Park for their hospitality and to Jennifer, Kelsey and Luis for organising such a thorough and fascinating workshop, it has been a great pleasure to be involved.


A fine bunch of herpetologists assembled for this mammoth undertaking!
