Abstract

This study aims to identify the species composition and estimate the potency for biomass, carbon and carbondioxide (CO2) uptake of understorey at a peat depth of 1 - <2 m; 2 - <4 m; 4 - <8 m and 8 - <12 m in Sebangau National Park Central Kalimantan. The results showed that the total number of understorey species found in all peat depths was 21 species. The most common understorey species found were at peat depths of 4 - <8 m, with 13 species. Several understorey species that dominate the entire peat depth are Pandanus tectorius, Pandanus amaryllofolius and Stenochlaena palustris. The potency of understorey biomass, carbon storage and CO2 absorption in all peat depths ranged from: 1.73 to 2.71 tons/ha; 0.81 - 1.30 tonC/ha and 2.98 - 4.77 tonsCO2/ha. Understorey that grows at a peat depth of 4 - <8 m has the highest potency for biomass, carbon and CO2 absorption.Keywords: biomass, carbon, carbondioxide, peat swamp forest, understorey

Abstract

This study aims to identify the type composition and estimate the potential for biomass and carbon deposits as well as carbon dioxide (CO2) uptake of peat swamp forest vegetation based on the growth rates (seedling, sapling, pole, tree). The estimation of potential deposits of vegetation biomass is calculated by destructive and non-destructive methods. The potential for carbon impedance is calculated using the formula Bof National Standardization (2011) and CO2 absorption with the IPCC formula (2006). The results showed that the number of vegetation types found was 44 types from 25 families. Stake-level vegetation is the most common type found compared to seedlings, poles, and trees. Tree-level vegetation is dominated by Cratoxylon arborescent BI, Combretocarpus rotundatus pole level, and Stemonurus secundiflorus Blume stake level., the seedling level of Anacolosa frutescens. The potential for biomass, carbon deposits, and CO2 uptake of peat swamp forest vegetation is 179.976 tons/ha; 84.588 tons C/ha; 310.442 tons CO2/ha, respectively. Tree-level vegetation has the highest deposits of biomass and carbon as well as CO2 uptake compared to seedling, sapling, and pole levels. Youth-level vegetation (seedlings, sapling, pole) in peat swamp forests has great potential in storing biomass, carbon, and CO2 uptake in the long term. Keywords: biomass, carbon, carbon dioxide uptake, peat swamp forest, vegetation

Abstract

Terjadinya keterbukaan tanah hutan dalam kegiatan pengelolaan hutan, salah satunya disebabkan kegiatan pembukaan wilayah hutan, seperti: pembuatan jaringan jalan hutan (jalan utama, jalan cabang, jalan sarad), TPn, TPK, base camp dan lain sebagainya. Penelitian ini bertujuan  (a) menghitung kerapatan jaringan jalan hutan, meliputi: jalan utama, jalan cabang dan jalan sarad; (b) menghitung persen keterbukaan tanah hutan akibat kegiatan pembukaan wilayah hutan (pembuatan jalan utama, jalan cabang, jalan sarad dan TPn. Lokasi penelitian di IUPHHK-HA PT Bumimas Abadi Kalimantan Tengah. Hasil penelitian menunjukkan bahwa kerapatan jaringan jalan hutan berkisar 3,54 – 36,48 m/ha. Persen keterbukaan tanah hutan akibat kegiatan pembukaan wilayah hutan (pembuatan jalan utama, jalan cabang, jalan sarad dan TPn) berkisar 0,42 – 10,21%. Jalan sarad memiliki kerapatan jaringan jalan hutan dan persen keterbukaan tanah hutan yang paling tinggi dibandingkan dengan jalan utama dan jalan cabang.

Abstract

The purpose of this study was to identify amphibian species in terrestrial and aquatic habitats and to analyze species diversity, species richness and species evenness indices in the Hampangen Educational Forest (KHDTK). The method used was strip transect observation with a transect length of ±400m and a left-right width of 5m. The selection of transects was done using purposive sampling. The results of the study showed that there were 7 species of amphibians found and identified in terrestrial and aquatic habitats from 3 families (Ranidae, Dicroglossidae, Rhacophoridae). The Shannon-Wiener diversity index (H’) for amphibian species in terrestrial habitats was 1.790 (moderate category) and in aquatic habitats was 1.078 (low category). The species richness index for amphibians in terrestrial and aquatic habitats is in the low category, with values of 0.291 and 0.513, respectively. Meanwhile, the species evenness index in terrestrial and aquatic habitats is in the high category, with values of 0.920 and 0.982, respectively. Keywords: amphibians, species diversity, terrestrial, aquatic, KHDTK
