There are various resources available to assist with the completion of the Global Amphibian Assessment (GAA).

The Global Amphibian Assessment Guide

This guide provides a practical step-by-step approach to assessing amphibians for the IUCN Red List. It introduces the GAA cycle, outlines the key stages involved in assessing species at a country or regional level, highlights useful mapping resources, and answers common questions about the assessment process.

Coming soon: A Portuguese translation is currently in development and will be added to this page as soon as it becomes available.

SIS Guide

This guide will help you navigate using the database behind the IUCN Red List – the Species Information System (SIS). This manual serves as a resource for navigating SIS and completing the relevant fields for an amphibian assessment. It also has a section for language and formatting, as well as a collection of useful links to additional IUCN resources for using SIS effectively.

This is available to download here.
