Cross River Gorilla Fact Sheet Common Name: Cross River Gorilla Scientiﬁc Name: Gorilla gorilla diehli Wild Status: Critically Endangered Habitat: Lowland forests Country: Mountains of the Cameroon-Nigeria border region, headwaters of the Cross River Nigeria Shelter: Forest Life Span: 35 to 50 years Size: Males 5'5" to 5'9" and 310 to 440 lbs Females 4'7" and 220 lbs Details: The Cross River Gorilla is a subspecies of the western gorilla. These gorillas like to live in forests and tropical jungles on the border between Nigeria and Cameroon. The Cross River Gorilla has opposable thumbs which helps them peel and eat fruit. They have also been seen using tools to ﬁnd food. Their main diet consists of tree bark, leaves, berries, nuts, some insects and sometimes small rodents. They live in groups with one male who is the alpha. The alpha male will mate with the females in the group and the female will give birth to one baby. The baby will stay with the mom until it's a few years old and able to be independent. The Cross River Gorilla is a critically endangered species because of habitat loss and hunting. Cool Facts: • There are estimated only 200-300 Cross River Gorillas left in the wild. • The biggest threat to the Cross River Gorilla is habitat loss caused by deforestation. • They are the most threatened of all the subspecies of gorilla. • The Cross River Gorilla is a subspecies of the Western Gorilla. • The Cross River Gorilla is one of the great apes. • Their only real predators due to their large size are leopards and crocodiles. • The Cross River Gorilla lives in groups which are led and protected by the alpha male. Taxonomic Breakdown: Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Primates Suborder: Haplorhini Infraorder: Simiiformes Family: Hominidae Subfamily: Homininae Genus: Gorilla Species: G. gorilla Subspecies: Gorilla gorilla diehli Conservation & Helping: It has been estimated that there are less than 300 Cross River Gorillas left in the wild. They are being threatened by bushmeat hunters and habitat loss. The government of Cameroon created Takamanda National Parkin an attempt to protect the gorillas. The Kagwene Gorilla Sanctuary was also created as part of IUCN's Cross River Gorilla action plan.

CRG exist only in a patchy distribution in the southern portion of the Cameroon-Nigeria border region and may have as few as 300 individuals remaining, divided into 14 fragmented subpopulations. Though Western gorillas (Gorilla gorilla spp) probably once inhabited much greater ranges throughout West Africa, today CRG represent the most northern and western distribution of all gorillas and are isolated from Western lowland gorilla populations by more than 250 km. CRG have proved challenging to study and protect, and many of the remaining subpopulations currently exist outside of protected areas. Very little is known about where the various subpopulations range on the landscape or why they occur in a patchy distribution within seemingly intact habitat. Active efforts are currently underway to identify critical habitat for landscape conservation efforts to protect the CRG in this biodiversity hotspot but, to date, a lack of understanding of the relationship between CRG ecology and available habitat has hampered conservation endeavors.

We assessed the socio-economic status and natural resource use of 3 villages bordering Mawambi Hills, an unprotected forest in southwest Cameroon, home to both the Critically Endangered Cross River gorilla Gorilla gorilla diehli and the Endangered Nigeria-Cameroon chimpanzee Pan troglodytes ellioti. This forest likely hosts one of the largest sub-populations of Cross River gorillas in Cameroon and is vulnerable to human influence given that it lies in close proximity to surrounding villages and is less hilly than other Cross River gorilla habitats. We show that employment opportunities in surrounding villages are rare, and people rely on agriculture and the collection of non-timber forest products (NTFPs), such as eru Gnetum spp. and bush mango Irvingia spp., for food and income. We also show that areas of heavy human activity coincide spatially with great ape nest sites and raise concerns about the potential impact of human activities on great ape survival at the site.

Cross River Gorilla Gorilla Gorilla Diehli
Cross River Gorilla Gorilla gorilla diehli Gorilla Agreement Action Plan This Action Plan is based on the following document: Regional Action Plan for the Conservation of the Cross River Gorilla (Gorilla gorilla diehli). Oates et. al. 2007. IUCN/SSC Primate Specialist Group and Conservation International, Arlington, VA, USA. Revised version of UNEP/CMS/GOR-MOP1/Doc.7b, November 2009 Incorporating changes agreed at the First Meting of the Parties to the Agreement on the Conservation of Gorilla and their Habitats (Rome, Italy, 29 November 2008) English Action Plans include additional editing not included in French versions. Action Plan Cross River Gorilla (Gorilla gorilla diehli) Species Range Nigeria, Cameroon Summary This plan outlines a programme of action that, if put into effect, could ensure the Cross River Gorilla‟s survival. The actions recommended are estimated to cost $4.6 million over a five-year period; around one-third of these funds have already been committed through government and donor support for general conservation efforts in the region. About $3 million therefore remains to be raised. The recommendations in this plan fall into two categories: recommendations for actions that need to be taken throughout the Cross River Gorilla‟s range, and site-specific recommendations. Among those that apply across the range of G. g. diehli are the following: • Given the nature of their distribution, a landscape-based approach should be taken for the conservation of Cross River Gorillas that must include effective cooperation by conservation managers across the Cameroon-Nigeria border. • There is a need to expand efforts to raise awareness among all segments of human society about the value of conservation in general and about the uniqueness of the Cross River Gorilla in particular.
