We present data on tree characteristics and vegetation structure in the interior of Arabuko-Sokoke Forest (ASF) and human-modified habitats (farmlands) on the eastern part of this coastal forest in Gede, Kilifi County Kenya. A total of 210 Point-Centered Quarter (PCQ) points were used to sample vegetation in each habitat type. Each PCQ point was ≥ 30 m distant from each other, and in each quarter of the PCQ point we recorded the following data: the nearest tree species of at least 20 cm Diameter at Breast Height (DBH), its crown diameter and distant of the tree from the centre of PCQ point. At the centre of each PCQ we also recorded percentage understory vegetation density and canopy cover. Results show that the interior of ASF was dominated by indigenous trees (Brachystegia spiciformis (30%), followed by Cynometra webberi (29%) and Manikara sansibarensis (18); while in the farmland it was dominated by exotic fruit trees (coconut (Cocos nucifera (54%), followed by mango (Mangifera indica (31%) and cashew nut (Anacardium occidentale (11%). The mean distance between trees (>20cm in DBH) in the farmlands (9.5M) was smaller than in the forest interior (10.95M). The % understory vegetation density of forest interior (38.2 ±1.5) was higher than that of the farmlands (5.8 ± 1.3). The % canopy cover of the forest (42.8±1.4) was more closed than that of the farmlands (29.3 ±1.9). This information provides a baseline information on the vegetation structure of the two main habitat types, and can be used to monitor habitat structure trends in the long run.
