One Day Technical Training on IUCN Red List of Ecosystems (RLE)

28/06/2018 - 09:00 - 17:00

The International Union for Conservation (IUCN) of Nature, together with its Commission on Ecosystem Management (CEM), are pleased to invite you to one-day training on The Red List of Ecosystems (RLE). This ecosystem assessment tool is a sister product to the IUCN’s influential Red List of Threatened Species methodology, and comprises five rule-based criteria for assigning ecosystems to a category of risk of collapse. The IUCN RLE, underpinned by strong scientific-foundations, evaluates the change in ecosystem distribution and function using quantitative measures and thresholds, to identify the level of risk of collapse of an ecosystem, thus informing better ecosystem management solutions and helping identify areas that need fast and effective actions to be preserved.

IUCN adopted RLE as a scientifically robust and consistent tool for evaluating the risk status of ecosystems, enabling comparisons between regions and over time to plan appropriate conservation actions, applicable at local, national, regional and global levels.

Requirements: a basic understanding of ecosystem management and ecological science is advantageous but not necessary

Registration: contact Leyma Prado ( to register by 25th June, 2018

More information:

The training will:

- Provide an overview of the methodology including key concepts, examples of completed assessments at national and global scales, and their applications

- Explain the set of five criteria and associated thresholds for performing evidence-based, scientific assessments of the risk of ecosystem collapse, as measured by reductions in geographical distribution or degradation of the key processes and components of ecosystems.

- Introduce the 8 categories for risk of collapse Collapsed (CO), Critically Endangered (CR), Endangered (EN), Vulnerable (VU), Near Threatened (NT), Least Concern (LC), Data Deficient (DD), and Not Evaluated (NE);

- Through targeted case studies, provide an understanding not only of how the criteria work together to assess risk, but how this information can be used to inform different types of policies and management decisions,

- Illustrate key components of the process of undertaking RLE assessments, and data and information requirements, through hands on preliminary experience and interactive group work targeted at different audiences.
