Abstract

This study aims to study and get a picture of species composition and structure of mangrove forests in logged-over areas of 2012, 2014 and 2016 at PT. Bina Ovivipari Semesta Kubu Raya District West Kalimantan Province. The method used in this study was the survey method by way of plotted path, where the laying of the path done by purposive sampling. The results of seedling to tree level showed that of 5 mangrove species found; Mangrove (Rhizophora apiculata), Tumu (Bruguiera gymnorrhiza), Lenggadai (Bruguiera parviflora), Nyirih Batu (Xylocarpus mullocensis) and Blukap (Rhizophora mucronata), the highest diversity index was owned by Rhizophora apiculata Blume species with values from 0.03-0.77; while the lowest diversity index was owned by Rhizophora mucronata species with a value of 0.01. From Index range values ranging from seedling to tree level indicates that the diversity index of logged-over areas of 2012, 2014 and 2106 of mangroves were in the low range.Keywords: mangrove forest, species composition, structure of mangrove.

Abstract

Area of IUPHHK-HA PT. Suka Jaya Makmur has planted three types of Shorea (Shorea leprosula, Shorea parvifolia, and Shorea johoriensis) at silvicultural system TPTI and TPTJ. The present study aimed at identifying the diameter increment of Shorea leprosula, Shorea parvifolia, and Shorea johoriensis which were planted by using silvicultural system of Indonesian Selective Logging and Plantation (TPTI) and Selective Logging and Line Planting (TPTJ). Data collection was done through a technique called purposive sampling. Results of the discussion showed that the diameter increment of Shorea leprosula was bigger than two other types of Shorea i.e. Shorea parvifolia and Shorea johoriensis. The analysis also revealed that there was a difference of the diameter increment between silvicultural system of TPTI and TPTJ. The diameter of TPTJ increased faster i.e. 3.46 cm/year in comparison with TPTI which was only 1.02 cm/year. Keywords: diameter increment, silvicultural system TPTI and TPTJ, three types of Shorea.
