Abstract:
A total of fourteen forests under government (nature conservation and exploitation), private and communal institutional
arrangements used by different local groups living in eight settlements were studied to determine the effect of tree
harvesting on the forest conditions. The fieldwork was conducted according to the guidelines of the 1FRI research
program me. There were significant differences in tlie occurrence of human consumptive disturbances among forests and
institutional arrangements. The distribution of disturbances were also significantly different between two distances
(within 30 km and between 30-80 km) from Kampala. However, the regression analysis indicated no significant functional
relationship between the distances and the forest variables tested. At both sapling and tree stages, there were significant
differences for species richness, the Shannon index, the Simpson index, basal area, and height between forests, as well as
institutional arrangements.
