Abstract
A study was conducted to determine the effects of different forest gap sizes on floristic composition in fragmented forest. Generally fragmented forests are experiencing rapid nature and anthropogenic disturbances due to lack of buffer zone. These disturbances contribute to forest gap created at canopy level of fragmented forests. The forest succession and restoration also take major part of the ecosystem actively. Five study plots with the dimension 20 m x 20 m were established in Bangi Forest Reserve. The selection of study plots were made by following the assigned Forest Gap Index FGI. The FGI is a qualitative monitoring based on the percentage of incident light entering the forest floor and crown openness. Five indicators have been used in FGI based on percentage of crown openness which were I 0 - 20 II 21 - 40 III 41 - 60 IV 61 80 and V 81 - 100. Tree inventory was conducted at each study plot where all trees 1 cm in DBH diameter at breast height were recorded. The measurement has been made on the tree DBH and local coordinate of each recorded tree. The result shows that 670 individual trees from 49 families and 181 species were recorded at all study area 0.2 ha. All individual trees were identified up to species level. Multivariate analysis was constructed to determine the existence of tree species based on the applied FGI and to identify the dominant species. This analysis revealed that similarities between studied plots were due mainly to the successional stage of the fragmented forest community.
