Located in Kirinyaga County, Kianyaga Valleys Key Biodiversity Area (KBA) is an idyllic landscape characterized by ridges, valleys and the meandering rivers Thiba and Mukengeria. It consists mostly of privately owned farms and is an important habitat for the endemic and globally threatened Hinde’s Babbler. The species lives in the dense bushes next to farm fences and also along riparian areas.
Despite their natural beauty, the Kianyaga Valleys face significant challenges threatening their biodiversity. The rapid growth in human population and subsequent demand for agricultural land have led to the clearing of bushes, the primary habitat of the Hinde’s Babbler. Local farmers have also planted exotic tree species, like Grevillea, as boundaries, and Napier grass along riverbanks and road reserves. These practices are beneficial to farmers but detrimental to the bird’s survival. Urbanisation and increased infrastructural development projects in the area, like the recent construction and commissioning of Thiba Dam, a large water reservoir, have exacerbated the situation. A recent visit to the site indicated that sightings of Hinde’s Babbler have become increasingly rare and that the community remains unaware of the existence of the KBA.
The future survival of Kianyaga Valleys’ biodiversity is delicate and can only be assured by concerted conservation efforts involving local communities. Community-led organizations like Castle and Kathandeini Community Forest Associations are leading in delivering conservation actions in the KBA. However, more efforts are required to promote practices that support livelihoods and conservation.
There is hope for Hinde’s Babblers, however, as the birds have also been seen in several areas around Thika, near Meru, in Makongo Forest in Makueni and in the new KBAs Mumoni and Mutitu Hills in Kitui County. Some Hinde’s Babblers have even reached Nairobi, with one bird recently caught, ringed and released at the National Museums of Kenya grounds!
