Global Marine Species Assessment Home


The IUCN Species Programme Marine Biodiversity Unit is conducting the first global review of the threat of extinction for every marine vertebrate species, plants and selected invertebrates – the Global Marine Species Assessment project. The project involves a range of partners in compiling and analyzing all existing data on approximately 20,000 marine species, and will determine the risk of extinction according to the IUCN Red List Categories and Criteria.

The Global Marine Species Assessment began in late 2005 and is headquartered at the Department of Biological Sciences at Old Dominion University, managed by Professor Kent Carpenter.
