IUCN Red List Status

Out of the 896 taxa considered in the region, 19 were not assessed because they are introduced or wandering species. Among the 877 remaining species and subspecies that were evaluated, 247 (28%) are categorized as threatened with extinction, out of which 61 (7%) are Critically Endangered (CR), 72 (8%) are Endangered (EN) and 114 (13%) are Vulnerable (VU). Of the total number of taxa assessed, 9% is Near Threatened (NT), while 42% is Least Concern (LC) (Table 8.1). A relatively high percentage of species (14%) are classified as Data Deficient (DD), which means that due to insufficient available knowledge on these species, they were not assigned to any of the Red List Categories. These species might qualify for a threatened category when more data become available and few of them, especially among the molluscs, are thought to be already extinct in the region.

The number of Extinct and Regionally Extinct species should be noted. In total, 18 (2%) of the species which are native to northern Africa are already extinct at the global level, and 32 (around 4%) are no longer present at the regional scale.

IUCN Red List Categories: EX - Extinct, RE - Regionally Extinct, CR - Critically Endangered, EN - Endangered, VU - Vulnerable, NT - Near Threatened, LC - Least Concern, DD - Data Deficient

 

23% of the species (199 species) are endemic to the northern Africa region, i.e., they do not exist anywhere else in the world, and therefore their regional Red List status corresponds also to their risk of extinction at the global level. Almost half of these endemic species (94 species) are threatened with extinction: 33 (17%) are Critically Endangered; 30 (15%) Endangered and 31 (16%) are Vulnerable at global level.

It should be noted that the majority of the 124 freshwater species assessed as Data Deficient (DD), due to lack of information, are aquatic plants (52 species; 6% of the regional total), freshwater fish (41 taxa; 5%), and freshwater molluscs (26 taxa; 3%) compared to the odonata and the crabs, which are the well known group with only 5 and none species listed as Data Deficient, respectively.
