kudu berry (Cassine aethiopica) and bush guarri (Euclea schimperi), and bushes such as turkey berry (Canthium spp.) and Polyspheria. In addition to these, they will eat sprouts, buds, and other fresh growth found at ground level. This duiker species can apparently manage without drinking, getting most of the hydration they need from their diets. These duikers have extremely specific habitat requirements, being found only in areas of old-growth thicket, with the highest population densities (11.4±5.18 per km2) recorded in relatively undisturbed high thicket. However, Kanga (1999) did report some Aders's duikers in secondary thicket. In the Arabuko-Sokoke Forest in Kenya, Aders's duikers inhabit regions of Cyanometra forest. Not much is known of its reproductive habits, although they may breed all year long. Conservation They are threatened by habitat destruction, feral dogs, and overhunting. They are particularly sought by humans due to their soft skin and meat. The population in Zanzibar had declined from 5000 in 1983 to 640 in 1999, and it will probably continue to decrease rapidly. In Kenya, the duiker is present at very low densities, though the decline is probably not as severe as the other population. Several conservation plans have been made, and a captive-breeding program has been proposed.
