Western gorilla (Gorilla gorilla)<br />
Savage, 1847<br />
Western Lowland Gorilla (Gorilla gorilla gorilla)<br />
(Savage, 1847)<br />
Red List: Critically Endangered<br />
Distribution: Angola (Cabinda only), Cameroon, Central African<br />
Republic, Congo, DRC (far western border near Cabinda<br />
only), Equatorial Guinea, Gabon.<br />
CITES: Appendix I since 1975<br />
CMS: Annex 1 since 2005<br />
Population: Fewer than 200,000. In 2008 the discovery of<br />
previously uncounted gorilla populations with higher than<br />
expected densities in northern Congo led to a reappraisal of<br />
the number of Western Lowland Gorillas. The widely reported<br />
figure of 125,000 ‘lost’ gorillas was erroneous because at least<br />
46,000 of this number had previously been counted (Stokes,<br />
et al., 2008). Nonetheless, the dense populations reported from<br />
Raphia swamps boosted population estimates to twice the previous<br />
estimate. This should not detract from the seriousness<br />
of the declines reported by Walsh, et al., 2003 (a 50 per cent<br />
decline in Gabon due to a combination of ebola and bushmeat<br />
hunting). The fact that ebola outbreaks pose a more serious<br />
threat to dense populations and the continuing threat of commercial<br />
bushmeat hunters led the IUCN Red List Assessment<br />
to retain the Critically Endangered status despite the revised<br />
population estimate.<br />
Cross River Gorilla (Gorilla gorilla diehli)<br />
(Matschie, 1904; Sarmiento and Oates, 2000)<br />
Red List: Critically Endangered<br />
Distribution: Nigeria (Cross River State only) and Cameroon<br />
(SW Province only).<br />
CITES: Appendix I since 1975<br />
CMS: Annex 1 since 2005<br />
Population: Fewer than 300, in 11 sub-populations this is the<br />
most endangered kind of gorilla. In the 1970s it was thought<br />
to be extinct in Nigeria and heading that way in Cameroon, but<br />
recent surveys conclude there are 75–110 individuals in Nigeria<br />
and 125–185 in Cameroon (Oates et al., 2007). The Cross River<br />
Gorilla featured in the IUCN list of the World’s 25 Most Endangered<br />
Primates 2008–2010.<br />
