Logging activities will have an impact on crop structure, composition, and species diversity. The research results showed that the composition and crop structure at each location were heterogeneous, as indicated by a very stable species diversity index. The types crop structure at the level of seedlings, stakes, poles, and trees from each location were also heterogeneous. There were, however, some of the same types encountered which dominated the locations of 2005, 2010 and 2015 such as Shorea sp, Dipterocarpus borneensis, Calophyllum inophyllum, Dehaasia sp., Syzygium sp. The stand density at the site in 2005 was lower compared to the two locations in 2010 and 2015, while the location of 2010 had the highest species density of 10,800 species/ha. The highest INP (Important Value Index) value in five species of plants in three locations was dominated by Shorea sp by 48.2%.
