  • Kenya: Conservation of Harrison's Giant Mastiff Bats on Mount Suswa

In Brief

Location:

50 km northwest of Nairobi on Mount Suswa volcano

Goal:

To conserve the Harrrison's long-eared giant mastiff bat at its breeding caves on Mount Suswa and to restore surrounding forests that the bats require for foraging on moths.

Conservation Value:

Harrison's large-eared giant mastiff bat (Otomops harrisoni) was described as a new species in 2015 and is known from two locations in Kenya, one being Mount Suswa (2,356 meters), an iconic shield volcano.  Conservation and protection of this species will benefit other cave-dwelling fauna as well as iconic species found in the surrounging area including zebras, giraffes, mongooses, turtles, hyenas and leopards.

Threats:

The globally Vulnerable Harrison's large-eared giant mastiff bat roosts in the volcanic caves of the iconic Mount Suswa Conservancy, representing crucially important maternity colonies.  This bat only gives birth to one pup per year and the species has declined rapidly since its discovery in 2015.  These caves are being impacted by expanding ecotourism, harvesting of guano, and blocking of cave entrances.  As well, uncontrolled clearing of the area’s forests for fuelwood and to create pasture impacts the bat’s foraging areas. 

Actions & Results:

Our field partner, Angaza Vijiji working with the Mount Suswa Conservancy, Maasai Mara University and the IUCN Bat Specialist Group, will investigate how bats use the Mount Suswa caves and their population status to improve management of the cave systems while promoting sustainable ecotourism and roost protection. We will engage communities to promote and catalyze protection and restoration of local forests (5000 hectares) as foraging habitats for bats and for other economically and ecologically important species. Local farmers and pastoralits will receive training on roost conservation, gating techniques, monitoring protocols, capitalizing on cooperative relationships to protect key roosts. Local guides will be trained as part of an education program for outdoor enthusiasts and local communities to increase understanding of the importance of conserving our target species and to increase visitation to the Conservancy.
