This guide describes, in pictures and words, all the different types of acacia trees that are such a distinctive feature of the Kenyan landscape. It shows both floral and vegetative characteristics - bark, leaves, pods, seeds - so that identification can easily be made even when the trees arenot in flower. This will be a valuable companion to anyone visiting or living in East Africa, and also to professional botanists, foresters, and ecologists. There are forty-four species of acacia in Kenya, out of twelve-hundred species globally, but they are of particular interest because they are both used by the local people and eaten by the wildlife. Acacias are also suited to commercial farming in arid conditions, which may be important if warmingtrends continue. The authors provide clear explanations of botanical terms, detailed field keys, and instructions for using the keys. No previous knowledge of plant sciences is required to enjoy this authoritative guide.
