|Scientific Name:||Otomys tropicalis Thomas, 1902|
Otomys dollmani Heller, 1912
|Taxonomic Notes:||This species was previously synonymized with O. irroratus. Current taxonomic research supports the distinctiveness of this species (S. Maree pers. comm.).|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||Taylor, P.J. & Maree, S.|
Listed as Least Concern because it has a wide distribution including several protected areas, a presumed large population, and its population is not believed to be in decline at present.
|Previously published Red List assessments:|
|Range Description:||This species occurs from southern Sudan, to northern Malawi, through Uganda, into the Democratic Republic of the Congo (Ruwenzori Moutntains range), Rwanda and Burundi, central and southern Kenya and Tanzania. It is found up to 4,500 m asl. The distribution of populations formerly recognised as Otomys orestes is unclear, but are generally confined to the type locality area of Teleki Valley, near the summit of Mount Kenya, in Kenya from 3,200 to 4,500 m asl. Animals formerly recognised as Otomys dollmani are known only from the type locality of Mount Gargues, in the Matthews Range of Kenya, just north of Mount Kenya at about 2,100 m asl.|

|Population:||Overall, it is a very common species. In the Democratic Republic of the Congo it has been recorded at 42.5 individuals/ha in disturbed savanna habitats, but in areas with fire regimes in place the populations are found to be much lower.|
|Current Population Trend:||Stable|
|Habitat and Ecology:||It occurs in a wide variety of habitats from lowland to montane grassland and also from swamps. It is also known from plantations such as coffee and banana.|
|Generation Length (years):||1-2|
|Major Threat(s):||There are no threats to this species. It can be a pest species causing damage to tree plantations.|
|Conservation Actions:||The range of the species includes a few protected areas. There is a need for further investigation into the taxonomic status of populations currently included within Otomys tropicalis.|
