The Tana River Primate Reserve is a critical protected area in coastal Kenya, famed for harboring Kenya's only endemic primate species amid diverse riverine and lowland forest habitats.
The Tana River Primate Reserve, located along the lower Tana River basin in southeastern Kenya, is a vital conservation area established to protect two endangered monkey species: the Tana River mangabey (Cercocebus galeritus) and the Tana River red colobus (Piliocolobus rufomitratus). The reserve encompasses unique riverine forests, swamps, acacia woodlands, and grasslands sustained by the seasonal flows of the Tana River—the longest river in Kenya. Covering parts of the coastal lowlands, the reserve's ecology is rich and fragile, supporting rare primates that depend strictly on these forest habitats. Historically, the reserve was designated in the 1970s following concerns about deforestation and habitat loss threatening the endemic primates. Its landscape is characterized by gallery forests along the river, which serve as biological corridors allowing animal movement and seed dispersal. Recreational opportunities in the reserve are limited due to the fragile environment and lack of extensive visitor infrastructure, but wildlife watching—especially primate observation—is the primary draw for researchers and eco-tourists alike. The area also provides excellent birdwatching, offering sightings of several rare and migratory species associated with riverine ecosystems. The reserve's appeal lies in its status as one of the few places where these highly specialized primates exist in the wild. Visitors and conservationists approach with care to ensure minimal disturbance to the sensitive habitats. Access is generally from nearby communities and small towns along the Tana River, with guided visits arranged through local conservation organizations.
