are living at the edge of the forests and farming the soil, which is very productive. Fifty percent of indigenous forests were replaced by exotic tree plantations between 1955 and 2004. The region was severely logged in the past and the remaining indigenous forest is now part of a nature reserve, the Taita Hills Wildlife Sanctuary. On the plains and foothills surrounding the hills, the land is predominantly used for cropping and grazing. The largest fragments of forest are located in the most inaccessible areas. The land is being degraded by deforestation, the lowering of the water table, and soil erosion. The annual rainfall varies from in the lowlands to more than three times this amount in the mountain zone. This area experiences two rainy seasons: March to May or June, and October to December, but the precipitation is very variable. Remaining forests are amazingly abundant with all forms of life Taita Hills are home to Small-Eared Greater Galago (''Otolemur garnettii'') and rare (but locally abundant)
