Acacia somalensis is endemic to Somalia, where it is known to occur only in the northern regions (Lower Shabele Region, Woqooyi Galbeed Region, Sanaag Region and Togdheer Region). Although the estimated extent of occurrence (EOO= 31,850 kmĀ²) does not meet the threshold for a threatened category, there are significant threats in the region and the species is not known to occur within the protected areas network at present. A. somalensis has been described as common in some areas, but due to the restricted distribution range and to the fact that little is known on the species health and on the population trend, a rating of Near Threatened is given as a precautionary measure, because if any future threats are identified it would automatically move this species into a threatened category e.g. VU D2 or VU B1ab(iii).
Further research should focus on confirming the exact distribution of this species and understanding the population trends and threats.

Habitat and Ecology [top]

Habitat and Ecology:A. somalensis is a shrub to 3 m high which occurs mostly at low altitudes near coast on gravel, rocky stony plains or hillsides. The species is known to occur in the Acacia-Commiphora bushlands and thickets, Ethiopian xeric grasslands and shrublands and Somali montane xeric woodlands ecoregions.

Threats [top]

Major Threat(s): The major threats to the Ethiopian xeric grasslands and shrublands, and to the Somali montane xeric woodlands ecoregions are widespread overgrazing and tree cutting for fuel and timber, particularly around the increasingly permanent settlements.

Conservation Actions [top]

Conservation Actions: There are no known conservation measures specifically for A. somalensis, and the species is not currently known to occur within the protected areas network. Samples of seed of A. somalensis should be collected and stored as an ex situ conservation measure.
