Summary

Loading map...
  • Nigeria-Cameroon chimpanzees (Pan troglodytes ellioti) are present in Ifon Forest Reserve.
  • The population size is unknown.
  • The chimpanzee population trend is unknown.
  • The site has a total size of 282 km².
  • Key threats to chimpanzees are logging and hunting.
  • Conservation activities are not documented.

Site characteristics

Ifon is found in the state of Ondo, Nigeria. The vegetation of Ifon is composed mainly of savanna-woodland but riverine forest and high forest also occur here. Four rivers run through it, the Osse, the Omo, the Owesse and the Okowa Rivers (Greengrass 2006).

Ape status

Chimpanzees may still be present in the site. During a 2005 visit to the site, a hunter reported the presence of chimpanzees (Greengrass 2006). In 2006, feeding remains were found in the reserve (Greengrass 2006). An up to date survey is needed to confirm chimpanzee occurrence.

Sampling methods Analytical frameworks

Threats

The site is under high pressure from hunting, logging and encroachment/land clearing for farmland around its boundary (Greengrass 2006).
