Vegetation diversity of feeding plant of Tapanuli Orangutan (Pongo tapanuliensis) in the land of other uses around the Batang Toru Forest Area, North Sumatera

Sutomo, Darma IDP, Priyadi A, Iryadi R. 2018. Trees species diversity and indicator species in Bedugul forest ecosystem, Bali, Indonesia. Biodiversitas 19: 2213-2218. Bedugul area is an endorheic basin landscape with 3 lakes namely, Beratan, Buyan, Tamblingan, which is surrounded by Bukit Mangu, Tapak and Lesung. Topography of the area shows sloping to steep slopes with altitude on the lake surface ± 1,100 m asl and the highest peak of Bukit Mangu 2002 m asl. Ecological studies have not been optimal so identification of comprehensive ecological potential is carried out. Measurement of tree vegetation diversity was carried out by Centered Quarter Method and important value ratio analysis and location elevation class. The results of the inventory of tree species diversity in the Bedugul Bali forest area recorded 35 species and 13 indicator tree species. From the number of indicator tree species in the Mangu hill forest area there are 5 types of Ficus sp, Platea latifolia, Polyosma integrifolia, Lindera sp. and Syzygium sp., Bukit Tapak forest area consists of 4 species, Casuarina junghuhniana, Acronychia trifoliate, Astronia spectabilis and Homalanthus giganteus, the forest area of Bukit Lesung consists of 4 types of Lophopetalum javanicum, Syzygium racemosum, Dysoxylum nutans and Dendrocnide peltata.

Point Line

This study aims to determine the Importance Value Index (INP), Vegetation Diversity Index, and abiotic factors in herbal strata in Bukit Gatan, Musi Rawas Regency. Determination of Herbs Strata Vegetation Diversity in Bukit Gatan Musi Rawas Regency using the point intercept method, which uses herbal touch rods that are below the touch point line. This research was made into 3 research study areas, namely study area A (1-10 stands), study area B (1-10 stands) and study area C (1-10 stands), then the data were analyzed descriptively quantitative. the highest importance index (INP) has been conducted in the study area A, the caladium (Caladium sp) of 50.33%, the study area B is the arrowroot (Maranta arundiciae) plant at 69%, and in the study area C is the bandotan plant (bandotan plant) Ageratum conyzoidez) by 39%. The average diversity of the Study Area A diversity index was 0.55, Study area B was 0.26 and Study area C was 0.33. Abiotic factors in the Bukit Gatan Region, Musi Rawas Regency, greatly affect the life of herbaceous strata in the Bukit Gatan Forest Area, Musi Rawas Regency. The air temperature in the gatan hill protection forest area ranges (28.30C) with soil moisture (15) while the humidity ranges (92.6%) while the soil temperature ranges (27.10C) and soil pH ranges (6.6).

Different Altitudes

East Nusa Tenggara located in the Wallacea area that has many endemic species. However, the existence of germplasm diversity in this area has been threatened due to landscape changes and deforestation. The research was conducted to identify floristic composition in Sikka forest area. This research also aimed to compare that plant composition in Sikka forest area on each of the different altitudes, including their diversity richness and environmental factors. Two sampling methods were used, which are Point-Centered Quarter (PCQ) method that applied for trees and nested sampling method 5x5 m2 for sapling and 2x2 m2 for ground cover. Measured parameters were Relative Density (RD), Relative Frequency (RF), Relative Coverage/dominance (RC), Important Value Index (IVI), Diversity Index (H'), and Jaccard Similarity Index (J’). Research results showed that the diversity index of each region was relatively low. Plant composition of tree, sapling, and groundcover in three different altitudes was quite different. This result indicates that the plant composition in the Sikka, East Nusa Tenggara is very diverse. The temperature and relative humidity in each altitude area observed was significantly different. One of the endemic species of Flores Island, Eucalyptus urophylla, was only found at 500-700 m asl. There are very limited research on the vegetation diversity held in Flores, East Nusa Tenggara. This research can be the basic for further research in order to explore the potential diversity of flora in this area.
