Justification: Listed as Endangered as the species has a distribution range of less than 5,000 km², the range is severely fragmented and there is continuing decline in the area and quality of habitat within the range of the species. |
|
| Range Description: | This species is endemic to the island of Madagascar, where it is restricted to the Menabe region in the south-west, south of Tsiribihina River, in an area probably no more than 900 km² (Schmid and Kappeler 1994; Schwab and Ganzhorn 2004). It is best known from the Kirindy/CFPF forests and Ambadira, but is believed to occur in the forests of Analabe just a few kilometers to the north-west. It formerly occurred in the Andranomena Special Reserve to the south (Schwab and Ganzhorn 2004), but it is not known whether it still occurs there. Sea-level to 150 m. |

| Population: | Although it appears to be adaptable and abundant where it occurs, its population is believed to be no more than 8,000 potentially breeding individuals (Schwab and Ganzhorn 2004). Densities of 100 individuals/km² have been recorded in patches where it occurs (suggesting high localized densities), but the overall generalized density is about one-third - probably in the order of 30/km². |
| Population Trend: |
Decreasing
|
| Habitat and Ecology: | This species inhabits an area of dry deciduous forest; perhaps occasionally in secondary forest. A solitary forager characterized by extensively overlapping home ranges, the ranges of males being substantially larger than those of females and more prone to seasonal fluctuation. Microcebus berthae is the world's smallest primate. |
| Systems: | Terrestrial |
| Major Threat(s): | The major threat to this species is habitat loss due to illegal logging and slash-and-burn agriculture. |
| Conservation Actions: | This species is listed on Appendix I of CITES. A 100,000-ha Central Menabe Conservation Site has been proposed, which will include a 30,000-ha strict conservation zone that includes the Kirindy Forest, the Analabe Private Reserve, and the currently unprotected Ambadira forests (Mittermeier et al. 2008). There are no animals reported in captivity at present (ISIS, 2007). |
