Abstract

Penelitian bertujuan untuk mengetahui keaneragaman jenis dan kesamaan komunitas vegetasi di areal perladangan berindah pada masa bera di Desa Hulu Tampang Kecamatan Dusun Utara Kabupaten Barito Selatan.  Hasil penelitian menunjukan keanekaragaman jenis pada tingkat semua tingkat pertumbuhan pada komunitas hutan dan komunitas bekas ladang umur 20 tahun termasuk klasifikasi sedang, kecuali tingkat pertumbuhan semai pada bekas ladang umur 40 tahun, pancang pada komunitas hutan, dan pohon pada  bekas ladang umur 20 tahun termasuk kategori rendah.  Tingkat kesamaan jenis vegetasi pada tingkat semai, pancang, tiang, dan pohon antar komunitas vegetasi termasuk klasifikasi rendah, kecuali untuk  tingkat kesamaan antara komunitas bekas ladang umur 20 tahun dan umur 40 tahun termasuk kategori tinggi.

Abstract

The purpose of this study was to determine the level of preferences and characteristics of orangutan nesting sites in Area Punggualas Sebangau National Park, Central Kalimantan using the strip transect method, a path 1 km long and 25 m wide on each side of the right and left lanes. Nest observations were carried out on 10 transects and the distance between transects was ±200 m. Based on observations of the habitat characteristics and preferences of orangutan nest trees (Pongo pygmaeus) in Punggualas, there are 13 tree species that orangutans like, namely Sagagulang, Bintan, Galam Merah, Kajunjung, Mahalilis, Pampaning, Tatumbu, Rasak, Tutup Kabali, Forest Mangosteen, Nyatoh bawui , Uweh, and Tarantang. The physical tree parameters (total tree height, tree diameter, nest height, and nest position) show X2Hitung > X2Tabel, which means that each variable has a relationship with the frequency of finding significant nests for orangutans to be nests.

Abstract

The existence of the Katingan Botanical Garden which will collect various plants (fruits, orchids, and various types of forest vegetation typical of Kalimantan) will be utilized and developed for research, education, cultivation, conservation, tourism, and environmental services. This study aims to analyze the diversity and reveal the rarity status of plant species in the Katingan Botanical Garden area, Katingan Regency, Central Kalimantan Province. The method used to collect vegetation data is the plot method in the form of quadratic transects. The size of the observation plot transect is 20 m x 500 m with 2 (two) transects. The research object is seedling, sapling, pole, and tree-stage vegetation. The composition of vegetation species found in the community unit (2,0 ha) is 28 species belonging to 17 tribes, in this, there are 2 individuals that have not been identified. Akasia (Acacia mangium), Tumih (Cambretocarpus rotundatus), and Gerunggang (Cratoxylum arborescent BI.) dominated at all growth stages. The biodiversity indices (diversity, richness, and evenness indices) are classified as medium, low, and high, respectively. There are 3 (three) plant species classified as IUCN status, namely Pulai (Alstonia scholaris) with Least Concern (LC) or low-risk criteria, Jelutung (Dyera lowii) with Vulnerable (VU) or vulnerable criteria, Kempas (Koompassia malaccensis) with Vulnerable (VU) or vulnerable criteria, and 1 (one) plant species including protected, namely Kempas (Koompassia malaccensis).

Abstract

This research aims to determine the diversity of species and population density of birds in the Lapak Jaru Forest Park (Tahura) Area. The method used is the Rapid Assessment method and a combination method between the Point Count method and Line Transect. Data analysis uses the Species Richness Index, Species Diversity Index, Evenness Index and Population Density. The research results showed that the number of bird species at the research location is 28 bird species with a total number of 238 individuals. The Species Richness Index obtained is 4,93, the Species Diversity Index is 2,96, and the Evenness Index is 0,89. The bird population density at the research location is 2,701.11 individuals/km2, and the five types of birds with the highest density are Cinenen Belukar (306,68 individuals/km2), Pentis Kalimantan (271,29 individuals/km2), Cucak Kelabu (235,9 individuals/km2), Asi Topi-Sisik (235,9 individuals/km2) and Jingjing Batu (176,93 individuals/km2)

Abstract

The purpose of this study is to examine the vegetation's composition and ecostructure surrounding the Ramin tree (Gonystylus bancanus) in the University of Palangka Raya's Natural Laboratory of Peatlands. Vegetation data collection was carried out using the quadrat plot technique, with the plot placement applied through purposive systematic sampling. The Importance Value Index (IVI), species dominance index, diversity index, and evenness index were employed to examine the data from this research graphic using Microsoft Excel. In this study, 47 different plant species from different communities were identified and divided into 38 genera and 27 families (trees, poles, saplings and seedlings). The greatest number of species were found in the groups Myrtaceae and Dipterocarpaceae. There are no dominant species in the area with Nyatoh, Jambu-jambu, and Mangkinang nearly always occupy the five dominant species ranks from seedling to tree level at all peat thickness levels. While the species evenness index in all plant communities and the level of peat thickness are in the high/abundance category of almost evenly (E = 0.76 – 0.95), the majority of species diversity index (Shannon-Wiener value) in the research plots are classified as high (H'>3), indicating that the condition of the forest ecosystem at that location is relatively stable.

Abstract

This research aims to describe and analyze species composition, species diversity, and dispersion patterns of rare plants, particularly those classified as critically endangered, in the Natural Laboratory of Peatland Palangka Raya University. Vegetation data collection was conducted using the quadrat plot technique based on a purposive systematic sampling. The data in the research plots were analyzed using Microsoft Excel, referring to the Important Value Index (IVI), species dominance index, diversity index, evenness index, and dispersion index. This research identified 47 types of plants (the total number of plants at the seedling, sapling, pole, and tree levels) categorized into 38 genera and 27 families. There were rare plants fall into critically endangered or endangered, namely ramin (Gonystylus bancanus) and nyatoh (Palaquium bintuluense). Nyatoh (Palaquium bintuluense), jambu-jambu (Eugenia spp.), and mangkinang (Elaeocarpus stipularis BI.) were almost always among the top five dominant species from the seedling stage to the tree stage at various peat thickness levels, but there was no concentration of species dominance in the plot. The majority of the species diversity index values (Shannon-Wiener) in the plots were classified as high (H’>3), indicating that the forest ecosystem conditions at the location are relatively stable. The evenness index of species in all plant communities and peat thickness levels fell into almost uniform abundance category (E = 0.76 – 0.95). The dispersion pattern of the population of critically endangered rare plants, such as Gonystylus bancanus (Mig.) and Palquium bintulense, at various peat thickness levels was clustered. In terms of growth stages, the population of Palquium bintulense was entirely clustered, while that of Gonystylus bancanus (Mig.) was only clustered at the sapling stage, but at the seedling and pole stages, it had random pattern.
