Acacia menabeensis is endemic to Madagascar, where it is only known to occur in a restricted area north of Morondava (Toliara province). Due to the restricted extent of occurrence (EOO = 200 kmĀ²) and the high level of threats to the dry deciduous forests and to the succulent woodlands habitats, this species is currently rated as Endangered. Further research and field work are required to better understand the distribution, health and populations dynamics of this species.

Geographic Range [top]

Range Description:Acacia menabeensis in endemic to Madagascar (Toliara province), where it is only known to occur in a small area north of Morondava. The specimen Leandri #475, which was collected in 1932 in Trangahy (Mahajanga), is not included in the species distribution range for this assessment, as there are no recent collections of the species from that area. This might suggest that it is not extant anymore at that locality and in the literature the species is mentioned to occur only in a small area north east of Morondova.

Habitat and Ecology:A. menabeensis is a deciduous shrub 2-5 m tall which grows on sandy soil in disturbed deciduous scrubland, with Baobabs and Adansonia fony. Sutherland (Sutherland #224) described the species as a very prickly Acacia, and he observed several pods and seeds in the collection locality.

Threats [top]

Major Threat(s): The major threats to the Madagascar succulent woodlands is fire, both intentional burning for expansion of agricultural lands and unintentional wildfires.

Conservation Actions [top]

Conservation Actions: There are no known conservation measures specifically for A. menabeensis, and the species is known to occur in only one protected area: Menabe Reserve. Seed of A. menabeensis should be collected and stored as an ex situ conservation measure.
