Nairobi grass rat

The Nairobi grass rat, Arvicanthis nairobae, is a rodent in the family Muridae. Its range covers Kenya and Tanzania, and the source allows that it may also occur in Ethiopia, so its presence there is treated as possible rather than settled. The natural habitat it names is dry savanna, which makes this a species of open, seasonally dry grassland country rather than forest. The Global Biodiversity Information Facility lists it as Least Concern on the IUCN Red List, so it is not currently regarded as at risk. The sources read for this entry say little about its diet, activity pattern, lifespan or body size, and those facts are left open here instead of guessed.
