Dominant food items of the Mount Elgon Vlei Rat are grasses such as Festuca pilgeri, Koeleria capensis , and Argostis gracilifolia (all Poaceae ) and flowers of Helichrysum (Asteraceae) . Breeding. Breeding of the Mount Elgon Vlei Rat is continuous, and reproductive individuals and juveniles can be found year-round. Activity patterns. The Mount Elgon Vlei Rat is presumably diurnal or crepuscular. Movements, Home range and Social organization. Mount Elgon Vlei Rats do not make nests. Home ranges overlap considerably and are 401-728 m® for males and 181-481 m” for females. Status and Conservation. Not assessed on The IUCN Red List. The Mount Elgon Vlei Rat has a restricted distribution and known negative anthropogenic impacts include uncontrolled fires resulting in habitat loss. Both conditions might justify classification as Endangered. Bibliography. Clausnitzer (2003), Monadjem et al. (2015), Taylor, Lavrenchenko et al. (2011), Taylor, Maree et al. (2014).
