Overview

Distribution

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 in press).

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 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’ duiker (C. weynsi), which occurs in the lmatong Mountains of south-eastern Sudan 400 km to the south-west, but is here treated as an isolated population of C. harveyi (following East 1999, Wilson 2001 and Kingdon and Rovero in press).

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

Justification
Listed as Least Concern as the species 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 threshold meriting a listing as Near Threatened. 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.

Population

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).

Threats

Major Threats
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.

Management

Conservation Actions

Conservation Actions
It is well represented in several protected areas, including Aberdares and Mount Kenya National Parks and Forest Reserves, and Shimba Hills and Tana River National Reserves (Kenya), Mount Kilimanjaro, Udzungwa Mountains, Mikumi, Arusha and Lake Manyara National Parks (Tanzania), Bush Bush National Park (Somalia) and Bale Mountain N.P. (Ethiopia) (Kingdon and Rovero in press).

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

Wikipedia

Harvey's duiker

Harvey's red duiker (Cephalophus harveyi) is one of 19 species of duiker found in Tanzania and scattered through Kenya, southern Somalia, and, possibly, central Ethiopia.

Harvey's duikers are roughly 40 cm (16 in) tall at the shoulder and weigh around 15 kg (6.8 lb), on average. They have mostly chestnut coats, but their legs and faces are black.

Harvey's duikers live in mountain and lowland forest, where they eat leaves, twigs, fruit, insects, birds eggs, and carrion. Although this duiker is not endangered, it is dependent on protected forestland. As of 2008, this species is of least concern.
