Scientific Name: Redunca fulvorufula ssp. adamauae Pfeffer, 1962
Parent Species:
Common Name(s):
English Western Mountain Reedbuck
Taxonomic Notes: Western Mountain Reedbuck (R. f. adamauae) is one of three recognized subspecies of Mountain Reedbuck (Redunca fulvorufula) following Ansell (1972) and Avenant (2013). The others are Southern Mountain Reedbuck (R. f. fulvorufula) and Chanler's Mountain Reedbuck (R. f. chanleri). The extent of genetic variation between the three forms has not been thoroughly investigated.

Assessment Information [top]

Red List Category & Criteria: Endangered C2a(i) ver 3.1
Year Published: 2017
Date Assessed: 2016-08-12
Assessor(s): IUCN SSC Antelope Specialist Group
Reviewer(s): Hoffmann, M.
Justification:
The Western Mountain Reedbuck is listed as Endangered because it has been reduced to small, declining, subpopulations within a very restricted range. There are estimated to be 1,000-1,100 mature individuals (well below 2,500), there is a continuing decline, and no subpopulation contains more than 250 mature individuals.
Previously published Red List assessments:

Geographic Range [top]

Range Description:The Western Mountain Reedbuck has been reduced to a small, declining remnant subpopulation in Nigeria in Gashaka-Gumti National Park (N.P.) and the Gotel Mountains adjoining the park’s southern boundary; and in Cameroon in the Adamaoua Mountains and the hunting zones below, as well as in the hunting zones between Benoue and Bouba Ndjida N.P. (East 1999, Nicholas 2004, Avenant 2013).

Population [top]

Population:East (1999) estimated a total of 450 Western Mountain Reedbuck. Nicholas (2004) estimated that there may be a few hundred within Gashaka-Gumti N.P., based on a small sample. There is no recent information from Cameroon, but assuming very broadly that a similar figure applies to the Adamaoua Highlands, which are unprotected, the total population is likely to be no more than 1,500 and declining. Subpopulations are small and rather isolated.
Current Population Trend:Decreasing
Additional data:
Number of mature individuals:1000-1100Continuing decline of mature individuals:Yes
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Western Mountain Reedbuck live on ridges and hillsides in broken rocky country and high-altitude grasslands (often with some tree or bush cover), from 1,500-5,000 m (East 1999, Avenant 2013). They are predominantly grazers and water is an important habitat requirement.
Systems:Terrestrial
Generation Length (years):5.0

Use and Trade [top]

Use and Trade: The Western Mountain Reedbuck is hunted for mainly for food. The proportions of animals taken from the wild is not available.

Threats [top]

Major Threat(s): The main threats to Western Mountain Reedbuck include the expansion of human settlement, poaching, disturbance, and hunting by dogs (Avenant 2013).

Conservation Actions [top]

Conservation Actions: Western Mountain Reedbuck occur in the Gashaka-Gumti N.P., while in Cameroon there is some protection from poachers in the hunting zones below the Adamaoua Mountains and in the hunting zones between Benoue and Bouba Ndjida N.P. (East 1999, Avenant 2013).
