Cephalophus ogilbyi ssp. brookei
|Scientific Name:||Cephalophus ogilbyi ssp. brookei|
|Species Authority:||Thomas, 1903|
|Taxonomic Notes:||Treated as a distinct species by Grubb and Groves (2001) and Grubb (2005), but here provisionally retained as a subspecies of Ogilby's Duiker following Wilson (2001) and Kingdon (2013).|
|Red List Category & Criteria:||Vulnerable C1 ver 3.1|
|Assessor(s):||IUCN SSC Antelope Specialist Group|
|Reviewer(s):||Hoffmann, M. & Mallon, D.|
Listed as Vulnerable because fewer than 10,000 mature individuals are estimated to exist and a continuing 10% decline in 14 years (three generations) is projected due to loss of primary forest cover and intensive poaching and snaring in many parts of the range. Rarely recorded in bushmeat markets and camera trap surveys. Numbers may in fact be low enough to qualify for Endangered under criterion C.

|Range Description:||Brooke's Duiker is endemic to the Upper Guinea Forest of West Africa, ranging from Sierra Leone to south-west Ghana. In Sierra Leone it is only confirmed in Outamba-Kilimi NP and Lalehun (Grubb et al. 1998, East 1999). In Liberia it has been recorded in the east and south east in Sapo NP, Grebo National Forest and Krahn-Bassa National Forest (East (1999). In Côte d'Ivoire it is known from Taï NP, Cavally-Gouin Classified Forest and adjacent sites in the south west; it is suspected to have occurred in Songan-Tamin-Mabi-Yaya forests in the south-east (East 1999). In Ghana it has been recorded only in forests of the south-west; it disappeared from Bomfobiir and Owabi Wildlife Sanctuaries (East 1999), but was observed in Kakum by Wilson (2001). There is a report from the Ziama-Diécké forests in south-east Guinea (East 1999) but this has not been confirmed.|
It appears to be scarce everywhere and records are few, but it is easily confused with Bay Duiker C. dorsalis and may be more widespread (East 1999).

|Population:||East (1999) estimated a total of 5,000 individuals based on a density of 2.0/km2 where it was common and 0.2/km2 elsewhere. Considered scarce in all parts of the range and there are few confirmed records. Brooke's Duiker is suspected to be declining.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||The species prefers primary forest but has been recorded in areas of mixed high/secondary or logged forest (East 1999).|
|Generation Length (years):||4.6|
|Use and Trade:||The species is hunted for bushmeat.|
|Major Threat(s):||This species is hunted for bushmeat throughout all or most of its range. Loss of high forest to logging and conversion to agriculture is also a threat.|
|Conservation Actions:||Listed in CITES Appendix II (as Cephalophus brookei). Occurs in several protected areas (Outamba-Kilimi NP (Sierra Leone); Sapo NP (Liberia); Taï NP (Côte d'Ivoire) and Kakum NP (Ghana).|
