Folder Red lists of threatened species

What are red lists of threatened species?

Several decades ago, the World Conservation Union (IUCN) started assessing the conservation status of species, subspecies, varieties and even selected subpopulations on a worldwide level. IUCN wanted to highlight which groups were threatened with extinction, in order to promote their conservation. In order to do so, it established a ranking system designating the risk that species encounter (e.g. being extinct, critically in danger, vulnerable, least concerned).

Since then, red lists of threatened species have been developed at a variety of scales, including at national and sub-national level.

Red lists in Belgium

Red lists are established at the sub-national level, since nature conservation is a competence of the Regions in Belgium. Each Region (Flanders, Wallonia and Brussels) proceeds with the establishment of its own lists. This is particularly the case for the animal and plant groups which are monitored on a regular basis, such as mammals, birds and vascular plants. For some groups, where national surveys have been carried out, red lists exist at the national level.

This page summarises existing information on red lists of threatened species of the Belgian fauna and flora. Whenever available, links are given to the relevant web sites.

The following table has been compiled from the Regional biodiversity websites, August 2014.
