Forest trees are an integral part of human society; they provide both direct and indirect benefits to humans. The aim of the study was to determine the human impact on tree species diversity and abundance by the local communities adjacent to Chemususu forest Reserve. Sampling was conducted in quadrats of 20m x 20m located along the transects at 500m intervals. In each of the plots, all the trees species were identified and counted. Indicators of human disturbance were assessed to determine the extent of human impact. Analysis of Variance (ANOVA) was used to test whether the mean number of cut stems and debarked trees varied with distance from forest edge.
