Anderson's mouse opossum  (Marmosa andersoni)

Anderson's mouse opossum is particularly vulnerable due to its intrinsically small range, and presumed tiny population. Despite the isolation of the region in which the specimens were found, the habitat still faces a number of threats, including expanding agriculture, overgrazing and unsustainable timber extraction (4). Such threats are likely to impact greatly on this tree-dwelling species.

There are no known conservation measures currently in place for Anderson's mouse opossum. It has been proposed that surveys should be undertaken to establish this species' population size and distribution (7), information that could then be used to implement appropriate conservation measures to protect this unique marsupial.
