Site description This site consists of remnant deciduous coral rag forest (dominated by Combretum schumannii) along a 12-km strip of Diani Beach, near Ukunda on the south Kenya coast. The formerly continuous forest has been cleared and fragmented, so that a set of small patches, in various degrees of intactness, now remains. Kaya Ukunda (a National Monument gazetted in 1992) has been left isolated as a 20 ha fragment slightly inland from the others, behind the Two Fishes Hotel. Twenty-one hotels, among other developments, occupy the Diani strip, and a busy road runs through the centre of some of the forest patches. Kaya Diani itself, which lies between Mworoni and Leisure Lodge Hotel, is not within this IBA.

Other biodiversity Diani was originally “one of the most diverse areas of forest along the Kenya coast with a rich coral rag flora”. The threatened mammal Rhynchocyon petersi (EN) occurs, but its current status is unknown. Diani supports an unusually high density of the primate Colobus angolensis, and is an important site for the restricted subspecies palliatus.
