Palangka Raya University Campus is a form of urban Green Open Space (GOS) that hasecological, social, cultural and aesthetic benefits. It is assumed that many trees which arepart of the green open space on the Palangka Raya University campus are experiencingunfavorable conditions. To obtain this information, a study was conducted using the foresthealth monitoring (FHM) method. The purpose of this study was to obtain data on thelevel of tree damage and the form of pests and diseases as well as human disturbance inthe green open space area of Palangka Raya University
Tarsier (Cephalopachus bancanus borneanus) is one of the endemic primates in Kalimantan. IUCN (International Union for the Conservation of Nature and Natural Resources) has established the conservation status of Cephalopachus bancanus borneanus as a vulnerable primate. This research was conducted in the Punggualas area, Sebangau National Park, from June to August 2019. The data collected was the number and distribution of tarsier population along with the composition and structure of vegetation. This study revealed that tarsiers in Punggualas have a tendency to live solitary. A total of 6 tarsier individuals were found in an area of ??4 km2, with a total length of 22 km of transects. The population in the scope of the study area is 23 individuals who occupy an area of ??4 km2 with a population density of 5,682 individuals / km2. The density of vegetation in Punggualas reaches 1179 individuals per hectare at the sapling level, where this area is a suitable habitat for shelter, locomoting, and as sleeping site for Tarsiers.
The purpose of this study (a) determine the composition and structure of vegetation based on the growth rate (tree, pole, sapling, seedling) in each Permanent Sample Plot (PSP); (b) to calculate the potency of biomass and carbon in vegetation trees level, poles and sapling on each PSP. The results showed that the number of vegetation species found in PSP-1 as many as 47 species with 28 family and PSP-2 of 33 species with 24 family. The vegetation of species that dominate based on the level of growth (tree, pole, sapling, seedling) in the PSP-1 consists of : Gerunggang (Cratoxylum arborescens (Vahl) Blume) and Jambu-jambu (Syzigium sp). In PSP-2 of vegetation species that dominance Tumih (Combretocarpus rotundatus (Miq.) Danser) and Jambu-jambu (Syzigium sp). The structure of the vegetation horizontally in the PSP-1 and PSP-2 dominated the vegetation of the small diameter and structure of the vegetation vertical in the dominance of vegetation including the stratum D. The average value the species diversity indexs vegetation tree level, pole, sapling and seedling in PSP-1 at 2.09 included in the category of “medium” and in PSP-2 of 1.83 which is included in the category of “low”. The potency vegetation biomass total in PSP-1 and PSP-2 respectively 152.69 tons/ha and 122.93 tons/ha as well as the potency carbon vegetation total in PSP-1 and PSP-2 respectively 71.76 tons/ha and 57.78 tons/ha.
Sebangau National Park (TNS) is a conservation area for peatland ecosystems with biological natural resources including medicinal plants namely Bajakah. The aims of this study were to identify and measure the composition and diversity level of Bajakah in TNS. Results of this study are expected to be a data baseline for TNS’ management especially the conservation of Bajakah. Data was collected using the observation method on a 15 plots study with analysis on the parameters of the Important Value Index (IVI), Species Diversity, and Species Evenness. Results of study recorded 6 species of bajakah in TNS, namely Akar Kuning, Bajakah Dango, Bajakah Darak, Bajakah Lunuk, Kalalawit Merah, and Kalalawit Putih. Based on IVI, Kalalawit Merah (Uncaria sp) is the most dominating (134,792 %), Species Diversity Index 1,36, and Species Evenness Index 0.759.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
