“…Based on the results of the calculation of the Important Value Index (IVI) at the study site in the Nusa Gede Panjalu Nature Reserve (Table 2), it was found that Dysoxylum densiflorum was the species with the highest IVI at the growth rate of seedlings (28.73%) and trees (23.72%), while at the pole level the species Litsea noronhae had the highest IVI (23.72%). The results obtained were not much different from previous studies at the same location in the Nusa Gede Panjalu Nature Reserve, with the most dominant genera Dysoxylum and Litsea (Rachman & Hani, 2017).…”

The Nusa Gede Panjalu Nature Reserve in Ciamis Regency is a conservation area that holds a variety of biodiversity and within it is a natural tourism area. It is feared that the existence of natural tourism areas will result in damage caused by human activities. This study aims to analyze the structure and composition of vegetation as well as environmental factors that affect vegetation growth in the Nusa Gede Panjalu Nature Reserve area. The method used in this study is the line transect method with sampling using quadrat. The data obtained were analyzed using the Importance Value Index (IVI), the index of Shannon-Wiener, and the index of Evenness. The results showed that the structure and composition of the vegetation in the Nusa Gede Panjalu Nature Reserve consisted of 416 individuals divided into 29 species. The plant species with the highest Importance Value Index (IVI) in the seedling category were Dysoxylum densiflorum (28.73%), the pole category Litsea noronhae (23.72%) and for the tree category Dysoxylum densiflorum (49.12%). The diversity index obtained is included in the moderate level of diversity. Environmental factors affecting the growth of vegetation in the Nusa Gede Nature Reserve are the temperature, humidity, light intensity, and pH with an average temperature of 28.4°C, humidity of 85.1% light intensity of 1070.1 lux, and pH of 6.3.

“…Based on this, the evenness species of vegetation in DSNR is relatively moderate (0.3 < E < 0.6) at the seedlings level growth rate and is considered high at the saplings, poles and trees levels. The value of the species richness index (d) < 3.5 indicates the species richness is classified as low, 3.5 < d < 5.0 indicates the species richness is classified as moderate and d > 5.0 species richness is classified as high [13] [19]. Thus, based on that, forest vegetation of Dolok Sipirok NR has a high species richness at all growth rates.…”

The Forest areas of Dolok Sipirok Nature Reserve (DSNR) and Dolok Sibual-Buali Nature Reserve (DBNR) are part of Batang Toru forest landscape which is also the habitat of some protected and endangered wildlife such as Tapanuli orangutans (Pongo tapanuliensis). However, the forest has continued to experience widespread pressure and degradation or reduction, mainly due to forest conversion. Therefore, it is very notable to assess the composition of forest vegetation of DSNR and DBNR considering their very important role for the survival of the Tapanuli orangutan populations. The composition of forest vegetation in this research is known by vegetation analysis. The method vegetation analysis used is line transect. The length of the line transect is 1000 m which consists of 10 plots of each transect with a distance between plots of 100 m. Measurements are carried out on the growth rate of seedlings, saplings, poles and trees. Furthermore, the processing of vegetation analysis data is carried out to find out the Important Value Index (IVI), diversity index (H’), evenness (E) and richness (d) of vegetation species in the research area. The results showed that the composition of orangutan habitat vegetation in DSNR consisted of 107 species from 39 families, while DBNR forest consisted of 117 species from 45 families. Tree Syzygium sp1. species consistently have the highest IVI scores at all forest vegetation growth rates of both reserves. The diversity, evenness and richness of DBNR forest vegetation species tends to be higher than DSNR forest.

“…Species diversity, especially for plants, is a parameter intended to compare two communities, especially to study the effect of biotic disturbances, to determine the level of succession or stability of a community [9]. [10] said that the diversity index is the high and low a value that indicates the high and low diversity and communities that have a higher diversity value, the relationship between components in the community will be higher.…”

Biodiversity is a term used for the degree of diversity of living natural resources, including the number and abundance of genes, species, and ecosystems in an area. Consists of various forms of life, their ecological role, and the diversity of germplasm contained therein. The purpose of this study was to examine the effect of changes in forest area designation on the diversity of understorey species. Data analysis used the method of placing plots in the lane using the plotted path method, with a plot area of 2 m x 2 m, by recording all understorey plants from sprouts to a seedling height of no more than 1.5 m. And also using the analysis of the important value index (INP) and species diversity. The results obtained from this study can be concluded that the species diversity in plantation forests is 3.470, in protected areas is 3.525 and in natural forests is 3.093. This shows that there is no serious effect on plant species diversity because the species diversity obtained shows results that are not much different between plantation forests, protected areas, and natural forests.
