In 2008, IUCN launched a process for establishing an IUCN Red List of Ecosystems that uses quantitative criteria to categorizing ecosystems according to their risk of rangewide collapse, using a process analogous to the IUCN Red List of Threatened Species. The standard for assessing the status of ecosystems at local, national, regional, and global levels is currently being refined with the goal of providing an initial assessment of conservation status of the world’s terrestrial, freshwater, marine, and subterranean ecosystems by 2025. NatureServe is contributing to a new continental effort, From Alaska to Patagonia: IUCN Red List of the Continental Ecosystems of the Americas, which will provide a demonstration of the approach for continental-scale applications. This webinar will provide an overview of the IUCN Red List of Ecosystems standard, the From Alaska to Patagonia initiative, and NatureServe’s ongoing contributions. We are seeking experts interested in providing information and peer-review for this pilot effort between November 2013 and May 2014. Please note: This webinar will last 1.5 hours.
