Taxonomy [top]

Kingdom Phylum Class Order Family
Animalia Chordata Mammalia Cetartiodactyla Bovidae

Scientific Name: Cephalophus harveyi (Thomas, 1893)
Common Name(s):
English Harvey's Duiker, East African Red Duiker, Harvey's Red Duiker
French Céphalophe de Harvey
Taxonomic Notes: Often treated as a subspecies of the Natal Red Duiker C. natalensis (Ansell 1972, Grubb and Groves 2001, Wilson 2001, Grubb 2005), but here retained as a separate species following Kingdon (1982), East (1999) and Kingdon and Rovero (2013).

Harvey's Duiker remains reasonably widespread and is well represented and common in protected areas in its range. Although declining, the rate of decline is not yet considered to have reached a rate meriting a listing as Near Threatened under criterion A. However, the long-term survival of Harvey’s Duiker is increasingly dependent on the maintenance of viable populations within national parks and reserves which are effectively protected against habitat destruction and illegal hunting.

Geographic Range [top]

Range Description:Harvey's Duiker occurs in central and south-eastern Kenya, north-eastern and central Tanzania, marginally in southern Somalia, and northern Malawi, there is a single record from Zambia (Kingdon and Rovero 2013).

In Ethiopia an expedition to the Harenna forest in the southern part of Bale Mountains National Park in 1986 produced positive sightings of a “red” duiker. This was the first confirmed sighting of a Cephalophus duiker from Ethiopia. There has also been a subsequent sighting of this duiker in the same area. While identification of the species awaits confirmation, it is considered highly likely to be Harvey’s Duiker. This species occurs in southern Somalia and could possibly have entered the Bale forests up the Juba and Genale valleys, a route which has been used by forest primates. In 1996, the presence of an unidentified species of red duiker was confirmed in dense bush around and north of the headquarters of Omo National Park in the south-west. The Omo population could be Weyns’s Duiker (C. weynsi), which occurs nearby in the Imatong Mountains of South Sudan 400 km to the south-west (East 1999, Wilson 2001, Kingdon and Rovero 2013).

Population [top]

Population:East (1999) produced a total population estimate of 20,000 individuals, but this must be a substantial underestimate. The overall population trend is downwards as pressures of habitat destruction and subsistence hunting increase with expanding human populations (East 1999).
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Harvey’s Duiker occurs in lowland and montane forests, isolated forest patches, riverine forest, coastal scrub, thickets and other habitats with thick cover (East 1999, Kingdon and Rovero 2013). Occurs to elevations above 2,400 m in some Eastern Arc massifs (e.g., in the Ulugurus; Doggart et al. 2004).
Generation Length (years):4.6

Use and Trade [top]

Use and Trade: It continues to be heavily hunted for its meat throughout most of its range, using both dogs and wire snares.

Threats [top]

Major Threat(s): The main threats are habitat loss due to timber extraction and encroachment of settlement, especially in the many coastal and montane forests. It continues to be heavily hunted throughout most of its range, using both dogs and wire snares.

In Somalia, this species was recorded from riverine habitats on the lower Shebelle and Juba Rivers and in coastal scrub and forest in the Lake Badana region, but by the mid-l980s, it had lost almost all of its habitat on the Juba and Shebelle Rivers to agricultural expansion and survived in only a few remaining patches of riverine forest on the lower Juba.

Conservation Actions [top]

Conservation Actions: It is well represented in several protected areas, including Aberdares and Mount Kenya National Parks and Shimba Hills, Tana River, Arabuko-Sokoke, Boni, Dodori, National Reserves (Kenya), Mount Kilimanjaro, Udzungwa Mountains, Mikumi, Arusha and Lake Manyara NPs (Tanzania) and Bale Mountains NP (Ethiopia) (Kingdon and Rovero 2013).

There is a need for further taxonomic work to investigate the status of this species relative to Natal Red Duiker.
