Assessment Information [top]

Red List Category & Criteria: Vulnerable A2cd ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Oates, J.F., Gippoliti, S. & Groves, C.P.
Reviewer(s): Mittermeier, R.A. & Rylands, A.B. (Primate Red List Authority)
Listed as Vulnerable as the species has been heavily impacted by both habitat loss and hunting in many parts of its range, and it is likely that it has undergone a decline exceeding 30% over the past 27 years (three generations).
Previously published Red List assessments:
1996 Lower Risk/near threatened (LR/nt)
1994 Vulnerable (V)
1990 Vulnerable (V)
1988 Vulnerable (V)

Geographic Range [top]

Range Description: This species ranges in coastal forests from western Nigeria into southern Cameroon, and throughout Equatorial Guinea (Rio Muni), and Gabon (Gautier-Hion et al. 1999) and the Gabon-Congo border on the Atlantic shore (Maisles et al. 2007). Its southern limit is south of the Ogooue River in Gabon. There have been unconfirmed reports of its occurrence into Benin, and if it ever did occur it may now be extirpated (Campbell et al. 2008). It is absent from Bioko Island.
Countries occurrence:
Cameroon; Equatorial Guinea; Gabon; Nigeria

Population [top]

Population: Although seemingly widespread, and sometimes locally abundant in scattered localities, the species now appears to be absent in areas with even low to medium hunting pressure (Maisels et al. 2007). It was already considered to be uncommon in Nigeria in 1982, and J. Oates (in Maisels et al. 2007) suggested that they may be naturally less common
in Cameroon and Nigeria because of competition with drills Mandrillus leucophaeus. However, in other areas large troops of both mandrills Mandrillus sphinx (which are in a similar niche to drills) and of White-collared mangabeys have been recorded living sympatrically.
Current Population Trend: Decreasing
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: This species is primarily found in high forest, but it also occurs in mangrove, gallery and swamp forest (Maisles et al. 2007). It can also be found in young secondary forests and around cultivated areas. Group size has been reported to be between 14 and 23 animals (Equatorial Guinea).
Systems: Terrestrial

Threats [top]

Major Threat(s): It is threatened by habitat loss and hunting for meat throughout most of its range. In places it is considered to be an agricultural pest.

Conservation Actions [top]

Conservation Actions: This species is listed on Appendix II of CITES and on Class B of the African Convention on the Conservation of Nature and Natural Resources.

This species is present in a number of protected areas including: Okomu National Park, Cross River National Park (Nigeria); Douala-Edea Reserve, Campo-Ma'an National Park, Banyang-Mbo Wildlife Sanctuary, Dja Reserve and Korup National Park (Cameroon); Sette Cama Forest Reserve and Mayumba, Loango, Moukalaba-Doudou, and Pongara National Parks (Gabon); Conkouati-Douli National Park (Congo); and Monte Allen National Park in Equatorial Guinea.
