Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2016-01-07
Assessor(s): IUCN SSC Antelope Specialist Group
Reviewer(s): Hoffmann, M. & Mallon, D.
The total population is estimated at some 280,000 animals. Although declining due to bushmeat hunting and habitat loss, it is not considered to be close to meeting any threshold for threatened status and it is confirmed Least Concern. However, if present trends continue, then the Water Chevrotain’s status is likely to decline further within the next few decades and a reassessment may be warranted.

Geographic Range [top]

Range Description:Has a disjunct range in West and Central Africa. It occurs in the Upper Guinea Forest from Sierra Leone and south-eastern Guinea, through Liberia and southern Côte d’Ivoire into south-west Ghana, there are recent camera-trap records of the species from south-eastern Guinea-Bissau in the Boé, extending the known distribution some way to the north-west (Hart 2013). It is also distributed through the Congo Basin forest of Central Africa from the Niger River through southern Cameroon, Gabon, Cabinda (Angola), Congo and DR Congo to extreme western Uganda, where it is now believed extirpated (East 1999, Hart 2013). A record from Angola's Lunda Norte Province, near the Cassai River, is the southernmost record Crawford-Cabral and Veríssimo 2005). Within this range, occupancy is restricted to the vicinity of rivers and streams (Hart 2013).
Countries occurrence:

Population [top]

Population:In the Ituri Forest, densities of 1.5-5.0/km²have been recorded (Hart 2013). Higher densities (28/km²) have been reported in Gabon (Dubost 1978). East (1999) estimated the total population size at around 278,000 animals, with populations generally in decline.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Chevrotains are confined to closed-canopy, moist tropical lowland forest, and within this habitat, they only occupy areas in the vicinity of streams and rivers. However, the Water Chevrotain is not a swamp specialist, and often ranges in mature upland forest areas (Hart 2013).
Generation Length (years):5.5

Use and Trade [top]

Use and Trade: The species is found in bushmeat market.

Threats [top]

Major Threat(s): The main threats to this species are habitat loss and bushmeat hunting. In the central Ituri Forest, chevrotains are regularly caught by the Mbuti net hunters, and consistently represent about 5% of total catch, even in areas that have been hunted for years (Hart 2013).

Conservation Actions [top]

Conservation Actions: Water Chevrotains occur in several protected areas, including: Sapo N.P. and Grebo National Forest (Liberia), Tai N. P. (Côte d’Ivoire), Lobeke N. P. (Cameroon), Lope N.P. and Minkebe N.P. (Gabon), Maiko N.P. Kahuzi-Biega N.P. and Okapi Faunal Reserve (DR Congo) and Odzala and Nouabale-Ndoki NPs (Congo) (East 1999).
