This species has been recorded from mid-elevations in southern Kenya, including around Nairobi. Its overall distribution and altitudinal range are still unclear because of confusion with Bufo lonnbergi and Bufo mocquardi, and the range map should be regarded as provisional.
Habitat and Ecology
There is no information on its habitat and ecology, although it is apparently a savanna woodland species that presumably breeds in water.
The population status of this species is unknown.
There is no information on threats to this species.
It might occur in some protected areas. More work is needed to resolve the taxonomic status of this species and its relatives.
This species was removed from the synonymy of Bufo lonnbergi by Poynton (1997) and included within B. mocquardi. However, we follow Channing and Howell (2006) in giving B. nairobiensis full species status. M. Tandy (pers. comm.) considers both B. mocquardi and B. nairobiensis to be synonyms of B. lonnbergi. More work is needed to resolve its taxonomic status.
