Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA MAMMALIA CETARTIODACTYLA BOVIDAE

Scientific Name: Madoqua piacentinii
Species Authority: Drake-Brockman, 1911
Common Name(s):
English Silver Dik-dik
Taxonomic Notes: Considered a distinct species following Yalden (1978) and Grubb (2005).

Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): IUCN SSC Antelope Specialist Group
Reviewer(s): Mallon, D.P. (Antelope Red List Authority) & Hoffmann, M. (Global Mammal Assessment)
Justification:
East's (1999) estimate suggested that the total population size could be up to 30,000 (and this was prior to the discovery of the species in the Ogaden of Ethiopia). No field data have been collected from its known range in Somalia for many years, and the extent of its distribution in Ethiopia (where it has only recently been recorded) and population density are unknown, as is information on whether these two reported areas of its range are disjunct or connected. This lack of information makes it impossible to reach a meaningful assessment. However, if current population trends continue, the Silver Dik-dik’s population will continue to decline to threatened.
History:
1996 Vulnerable
1994 Insufficiently Known (Groombridge 1994)

Geographic Range [top]

Range Description: The range of the Silver Dik-dik is usually given as being confined to the central coastal plain of Somalia, where its range does not appear to extend for more than 10 km inland from the coast (Simonetta 1988; East 1999). Recently, this species has been reliably reported (and photographed) further up the Shebelle River valley and in the valley bottoms of its seasonal tributaries in the Ogaden of Ethiopia (Wilhelmi et al. 2006).

Population [top]

Population: East (1999) produced an estimated total population of 30,000, perhaps an overestimate, since hunting pressures and other disturbances are relatively high within the Silver Dik-dik’s restricted range. In the Ethiopian Ogaden, where this species is probably on the very edge of its range, a density of 1–2 individuals was estimated in an area of less than 2,000 m² (Wilhelmi et al. 2006).
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: The Silver Dik-dik occurs in very low, dense thickets growing along the central Somali coastal littoral on fertile, sandy soils under a powerful offshore wind which has a cooling and moisturising effect (Kingdon 1997). In the south-eastern part of the Ethiopian Ogaden, Silver Dik-dik have been observed in dense to semi-dense Acacia-Commiphora bushland (Wilhelmi et al. 2006).
Systems: Terrestrial

Threats [top]

Major Threat(s): The habitat of the Silver Dik-dik is threatened by increased human presence and activity, e.g., during the worst period of the civil war many people fled along the coastal roads which were also used by large numbers of heavily armed fighters and their vehicles. Its skins are highly valued for handcraft products.

Conservation Actions [top]

Conservation Actions: This species is not known to occur in any protected areas, and no animals are held in captivity. The decline of this species can only be reversed by the establishment of secure protected areas within its range and/or the establishment of a secure, self-sustaining captive population (East 1999). Given the recent discovery of this species in the Ogaden, further surveys to better understand the range of this species are required.
