Grandidier's tufted-tailed rat

Grandidier's tufted-tailed rat is endemic to Madagascar.[1] It normally lives in middle to upper montane forests between the heights of 1,250 and 1,875 m (4,101 and 6,152 ft).[2] It resides in both the Northern Highlands and the northern part of the Central Highlands in eastern Madagascar.[2]

Grandidier's tufted-tailed rat is present in sclerophyllous forest and is presumed to be a partly scansorial species.[1] The species is forest depended and has not been captured outside of forest or in alpine grasslands, though it may occur just below the tree line.[1]

Female Grandidier's tufted-tailed rats are believed to give birth to up to three young.[1]

Grandidier's tufted-tailed rat is listed as Least Concern on the IUCN Red List due to its widely dispersed localities.[1] The population trend of the species, however, is unknown.[1] There is deforestation in the habitat of the Grandidier's tufted-tailed rat for conversion to cultivated land, but there is not enough population loss from this deforestation for the species to be listed as more threatened.[1] There is sufficient evidence that all species from the family Nesomyidae, especially those that commonly live upwards of 800 m (2,600 ft), are susceptible to a 100 percent mortality rate from plagues carried by introduced rodents, and these seem to be localized events.[1] The species is located in three protected areas: the Anjanaharibe-Sud and Manongarivo Special Reserves and the Marojejy National Park.[1]
