Pinus Jantho Forest (PJF) Nature Reserve has unique characteristics and distinctive ecosystem that plays an important role in the preservation of germplasm and the protection of natural resources. The sustainability of the PJF Nature Reserve is strongly determined by vegetation of its constituents. Therefore, an effort is needed to help its management properly, one of which is by knowing the diversity of plants that make up the community in PJF Nature Reserve. The purpose of this research is to analyze the composition and diversity of plant species in PJF Nature Reserve. Data collection and sampling were done using multiple square method. The plots were laid out by systematic sampling. PJF Nature Reserve composed of 111 species from 46 family. The seedling and understorey have the highest number individuals (1028 in total). Then there are 240 individuals at sapling level, 108 individuals at pole, and 72 individuals for tree.  The Euphorbiaceae family has the largest number of species (11 species). The highest Important Value Index (IVI) for seedlings and understorey, sapling and pole, and tree respectively were Chloranthus elatior (11.09%), Piper aduncum (21.90% and 19.32%), and Pinus merkusii (25.52%). The Diversity Index indicates a high level of plant species diversity (3.25-3.63).

The detailed causal factors of flood have not been established, whether because of the damage of upper watershed, sedimentation resulting in shallow river, forest conversion, the decrease in abundance and structure or high rainfall. The study aimed at finding out the species diversity and structure of the limited production forest (LPF) from the seedling to the tree stage of Arui watershed in Manokwari district. The species diversity was determined based on Shannon-Wiener index, while vegetation structure was determined based on Importance Value Index. There were totally 92 plots of samples drawn using systematic sampling. The results of vegetation analysis showed that there were 174 species of 43 families with the species diversity of 1.5-1.8 that was categorized as moderate. The four dominant species that were always found in seedling, sapling, pole and tree stages included: Pometia pinnata, Teijsmanniodendron bogoriense, Chisocheton ceramicus, and Horsfieldia irya. The conversion of the LPF into non-forestry sector for the purpose of accelerating development must be reviewed by considering hydrology, land, biodiversity, and social and regional aspects in order to prevent and to reduce flood in the coming days.

Ecological study with special attention to vegetation analysis has been done in the Bintan forest area, Riau Archipelago. Based on three sampling plots of 30 × 30 m, there were 73 tree (dbh ≥ 5 cm) species were recorded, belong to 64 genera and 32 families. The density is fairly high (1,485 individuals /ha) with total basal area relatively low (27.71 m2/ha).  Its indicates that most of trees are small size. Similarity index among study sites are relatively low (< 25 %), indicates that there is strong relation between habitat and species composition. Out of the 6 most common tree species in the study area, only Dipterocarpus gracillis was dominant in 2 study sites. Overall species diversity is relatively low, which is characteristic of forest vegetation on small islands.

Punti Kayu Natural Tourism Park is a conservation forest contained in Palembang with an area of 50 hectares. Conservation forest utilization as a natural tourism park has a fantastic tourism development potential. Considering this matter, it is necessary to research about vegetation analysis at Punti Kayu nature tourism park for tourism development at Punti Kayu Palembang. The purpose of this research is to know the composition and structure of tree vegetation at TWA Punti Kayu Palembang. The research was conducted from April to June 2017. The method used in this research is Simple Random Sampling with 63 plot total sample.The results of this study obtained 24 tree species consisting of 949 tree phases, 114 pole phases, 141 sappling phases, and 375 phases of seedlings.Tree phases was dominated by Pinus Spesies with total 750 trees (INP 212,65%), in the pole phase, sapplings phase and seedling phase were dominated by Talok with total 25 poles (INP 57,96%), 17 sapplings (INP 39.89%) and 60 seedlings (INP 29.51%), The level of diversity of tree species and seedlings included in the low category, the tree of 0.493 and the seedlings of 0.824. One characteristic of good vegetation is the high level of species diversity. according to Kristinawanti et al (2013) good tree vegetation will have a positive impact on increasing tourist visits The results of this research can be used to support tourism in Punti Kayu Nature Tourism Park because it can be used as a reference to assess the management of Punti Kayu Nature Tourism Park.
