IUCN Red List of Threatened Species - Regional Assessment

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. This study is based on the collation and analysis of existing information, and the knowledge of regional experts.

This report reviews the conservation status of all native marine fishes occurring in the Mediterranean Sea, based on the assessments for 513 species and 6 subspecies using the IUCN’s Red List methodology. It identifies those marine fish species that are threatened with extinction at the regional level so that appropriate conservation actions can be taken to improve their conservation status.

Biodiversity within inland water ecosystems in the Eastern Himalaya region is both highly diverse and of great regional importance to livelihoods and economies. However, development activities are not always compatible with the conservation of this diversity, and the ecosystem requirements of biodiversity are frequently not considered in the development planning process. One of the main reasons cited for inadequate representation of biodiversity is a lack of readily available information on the status and distribution of inland water taxa.

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.

Lack of readily available information on the status and distribution of inland water taxa in western Africa explains why biodiversity is often poorly represented within the development planning process. In response to this need for information, a regional assessment of the status and distribution of 1,395 taxa of freshwater fishes, molluscs, odonates, crabs, and selected families of aquatic plants from across western Africa was conducted.

The European Red List is a review of the conservation status of c.6,000 European species (mammals, reptiles, amphibians, freshwater fishes, butterflies, dragonflies, and selected groups of beetles, molluscs, and vascular plants) according to IUCN regional Red Listing guidelines. It identifies those species that are threatened with extinction at the regional level in order that appropriate conservation action can be taken to improve their status. This is the first assessment of the Red List status of Europe's saproxylic beetles, that is beetles depending on wood decay.

The European Red List is a review of the conservation status of c.6,000 European species (mammals, reptiles, amphibians, freshwater fishes, butterflies, dragonflies, and selected groups of beetles, molluscs, and vascular plants) according to IUCN regional Red Listing guidelines. It identifies those species that are threatened with extinction at the regional level – in order that appropriate conservation action can be taken to improve their status. This study has evaluated 137 species and subspecies present in Europe. It shows us that about 15% of European dragonflies are threatened.

The European Red List is a review of the conservation status of c.6,000 European species (mammals, reptiles, amphibians, freshwater fishes, butterflies, dragonflies, and selected groups of beetles, molluscs, and vascular plants) according to IUCN regional Red Listing guidelines. It identifies those species that are threatened with extinction at the regional level – in order that appropriate conservation action can be taken to improve their status. This comprehensive assessment of all European butterflies provides an overview of the conservation status of this important insect group.

Este informe presenta una revisión del estado de conservación de 165 especies de libélulas presentes en la cuenca del Mediterráneo, según los criterios de la Lista Roja regional de la UICN. En él se identifican las especies que están amenazadas de extinción a nivel regional a fin de que se puedan tomar las medidas apropiadas de conservación para mejorar su estado.

This volume gives the most up-to-date information on the distributions and conservation status of species in all inland water ecosystems across mainland continental Africa and the reasons behind their declining status. This represents the most comprehensive assessment yet of freshwater biodiversity at the species level for an entire continent. For managers, this information will assist in designing and delivering targeted action to mitigate and minimise these threats.
