KBAs in Focus – Taita Hills Forests

Located in southeastern Kenya within Taita Taveta County, the Taita Hills forests constitute a Key Biodiversity Area (KBA). Perched high on a series of ancient hills rising above the dryland plain, the Taita Hills forest fragments are like forest islands. These isolated forest fragments are known for their highest levels of endemism globally and form the northern part of the Eastern Arc Mountains. The forests include Ngangao, Iyale, Susu, Mbololo and Fururu, among others, managed by the Kenya Forest Service, while Chawia and Vuria are under the management of the county government of Taita Taveta.

The KBA provides crucial habitat for numerous endemic, endangered, and critically endangered species. Some species are found exclusively within this area, making it an Alliance for Zero Extinction (AZE) site. Notable species include the Taita Apalis, Taita Hills warty frog, Taita Thrush, Taita Hills purple-glossed snake, Taita Hills caecilian and Taita dwarf shrew.

Other globally threatened species reflecting the KBA’s critical conservation importance include the Taita White-eye, the endangered limbless Sagalla caecilian (which lives in the soil and leaf litter of the forest), the vulnerable small nocturnal primate known as the Taita Mountain dwarf galago (bushbaby), and the Taita blade-horned chameleon, among many others documented or yet to be discovered.

Despite the indisputable uniqueness of the KBA, it faces serious threats. These include rapid forest fires, mainly intentionally caused by community members clearing land for agriculture or due to the myth that forest fires lead to assured rainfall. The intensification of land use around the forest patches, driven by rapid population growth, has increased encroachment on the forests for agricultural production. Other threats include forest fragmentation, forest grazing, and climate change impacts. Additionally, the forests are threatened by an invasive species of dodder plant (Cuscuta sp.), a parasitic vine that grows rapidly, entwining and parasitising host plants, potentially threatening the survival of the forests and their biodiversity.

Conservation efforts that focus on preserving and restoring these diverse forest fragments are essential for ensuring the survival of the unique biodiversity they harbour. Concerted efforts by the national government, county government of Taita Taveta, non-governmental organisations, and local community members are evident. Taita Taveta County was the first to sign an agreement with the national government regarding the devolvement of forestry in 2013/14. The county has been at the forefront of developing forest management plans for Chawia and Vuria forest fragments and is actively formulating the forest and landscape restoration implementation plan (FOLAREP). The community, through a local conservation group known as the Dawida Biodiversity Conservation Group (DABICO), in partnership with Nature Kenya, is sensitising the community about preventing forest fires, discouraging the use of the dodder plant for beautification purposes, and participating in other initiatives such as ‘adopt-a-forest’ to enhance restoration of degraded forest landscapes within the Key Biodiversity Area (KBA).
