In the Rift valley of Kenya, farmers have long practised traditional forms of agroforestry using indigenous species combined with some use of exotics (eucalypts, cypress and grevillea) for poles, timber and fuel. Pastoral communities manage the scattered indigenous trees to play an essential role in meeting subsistence requirements.

In the Kenyan highlands, with greatly increased population pressure, intensively managed exotic leguminous trees for fodder and green manure production are common. In these areas, there is greater, not reduced use of tree species. The result is a forest mosaic. The traditional species are not disappearing, they are being combined with a variety of new species to fill complementary roles.
