【 摘 要 】

Peat swamp forest is one of the wetland tropical rainforest ecosystems widespread in Indonesia. This study aimed to analyze plant species diversity of tree stage in difference logged-over peat swamp forests at PT. Diamond Raya Timber, Riau Province. This study site was divided into three different locations, newly logged-over peat forest swamp forest (NLPSF), three years logged-over peat swamp forest (3LPSF) and four years logged-over peat swamp forest (4LPSF). Primary species of tree stage in the study site were grouped into three parts, i.e., firstly, Dipterocarpaceae family mainly consists of meranti bunga (Shorea teysmanniana) and meranti batu (S. uliginosa), secondly, non-Dipterocarpaceae included balam (Palaquium hexandrum), milas (Parastemon urophyllus), macang (Mangifera havilandii), punak (Tetramerista glabra), jambu (Eugenia sp), pisang-pisang (Mezzetia parviflora), and arang-arang (Gynotroches axillaries), and thirdly, particular species of ramin (Gonystylus bancanus). The pattern of species grouping for tree level was more centered in the NLPSF compared to other sites. On the other hand, species diversity in tree level found more diverse in 4LPSF, suggested the various ecological parameters. Cluster analysis showed the occurrence of species relationship in the sites based on diameter and importance values indicated the presence of species similarity and habitat preference.
