    Abstract

    The diversity and composition of tree species of the tropical lowland forest will change, when there are fragmentation and changes of landscape structure of natural forest, and the dynamics of changes in the composition and diversity of trees species occur in the landscape [1]. However, there are variations among the study areas, which can be determined by tracing the linkage and interaction among indicators of changes in the composition and diversity of tree species [2]. The research objectives are to examine the the trees species diversity forest, and interactions between species on the landscape structure change in the Meranti-Dangku forest, to better understand the effects of landscape modification against individuals and groups of species. We expect that the research findings can be used to enhance the efforts on the forest restoration and biodiversity conservation. We applied a tree vegetation analysis of fragmented natural secondary forest, and conducted observations in 32 units of sample plots, whose size is 20m x 50m. Ecological analysis of all tree species with dbh ≥ 10 cm was conducted by identifying the local name, latin name of the tree species, and its typical characteristics, and then making the sample of herbarium. Hill’s Diversity Number produced a family of number related to diversity, effective species richness, a rare species and the abundance of common species in the population [3]. We also calculated the importance value index of tree species and the Jaccard similarity index, to differentiate the level of the forest succession and the gradation among sub-landscape. The results showed significance of some parameters, which has played important roles in the detecting changes in biodiversity, namely index of species richness and species evenness, and basal area of a tree stand. Three other parameters are not significant. The changes of the tree species composition of the natural forest succession, as respond to the changes of landscape structure, and the gradation among sub-landscape, can be used as a reference on species selection in rehabilitation and restoration of the fragmented natural forest, as a part of the planning on human-modified landscape.
