Range and habitat

Madame Berthe's mouse lemur is known to live in Kirindy Forest in Madagascar. Because of the high rate of deforestation in the surrounding Menabe forests (52%) between 1985 and 2000, less than 22,000 hectares (54,000 acres) of inhabitable forests remained between Kirindy Park, the Tsiribihina River, and the Reserve. Given that this lemur occurs at 0.36 lemurs per ha, it is estimated that about 7,920 mouse lemurs were left in the area in the year 2000.
