Species - red data listings

When making assessments at regional levels it is also particularly important to recognize that while IUCN Red List Categories reflect the relative extinction risk of species, the process of setting priorities for conservation actions may require several additional considerations. As a consequence, the following guidelines were produced to assist in the application of the IUCN Red List Categories and Criteria at regional levels.

The Western Ghats is one of the world’s most heavily populated biodiversity hotspots providing for and supporting 400 million people through water for drinking, transport, irrigation, and hydroelectric power, together with food and resources to sustain livelihoods.

With the highest percentage of threatened sharks and rays in the world, the Mediterranean region is in need of regional planning and policy development for the conservation and sustainable management of chondrichthyan fishes. This third report in the series of Mediterranean Red List Assessments presents the findings of an expert workshop at which 71 Mediterranean species of sharks, rays and chimaeras (cartilaginous fishes) were assessed using the IUCN Red List categories and criteria.

One of the main reasons cited for inadequate representation of biodiversity in the development processes is a lack of readily available information on inland water taxa. In response to this need for basic for information on species, the IUCN Species Programme conducted a regional assessment of the status and distribution of 2,261 taxa of freshwater fishes, molluscs, odonates, crabs and selected families of aquatic plants from throughout central Africa.

The threatened species categories used in Red Data Books and Red Lists have been in place for almost 30 years. The IUCN Red List Categories and Criteria provide an easily and widely understood system for classifying species at high risk of global extinction, so as to focus attention on conservation measures designed to protect them.

This assessment is the first overview of the conservation status of 877 northern African freshwater species belonging to five taxonomic groups—fish, molluscs, dragonflies and damselflies, freshwater crabs and aquatic plants—in accordance with the IUCN regional Red List guidelines. Species at risk of regional extinction are mapped and conservation measures are proposed to reduce the probability of future declines.
