Mangrove Diversity in Production Forest Management Unit (FMU) Bulungan Unit VIII North Kalimantan

Mangrove ecosystem have various important roles as habitat for marine and terrestrial species. However, the ecosystem has recently faced anthropogenic threats delivered by the expansion of aquaculture pond. Study of mangrove diversity was conducted in Production FMU Bulungan Unit VIII, North Kalimantan. The study was aimed to analyze species diversity in the FMU Bulungan Unit VIII and determine community perception on existing mangrove condition. Vegetation analysis was applied to quantify mangrove community in two sampling locations, Salimbatu and Liagu, within 26 quadratic plots (10mx10m). As many as 63 respondents were interviewed to analyze communities\u27 perception. As the result, 10 species were identified species and one unidentified species recorded during the survey. Rhizophoraceae was dominated the species composition in sampling area. Rhizophora mucronata had the highest Importance Value Index in tree and seedling stage while Rhizophora apiculata was dominant in sapling stage. On the other hand, Bruguiera parviflora was recorded on each growth stages in all sampling plots. Species diversity index (H\u27) of mangrove vegetation in the FMU was found at 1,68 with species richness index value 1,58. This diversity index considered as moderate diverse since only few vegetation species are able to live in the mangal. The perpendicular structure of mangrove in the FMU formed an inverse J-shape which showed normal growth of uneven-age forest stand. The interview result implied that more than 50% of the respondent considered that mangrove condition in their village area has been disturbed. Therefore mangrove management with local community involvement is neccessarily required to improve the mangrove performance

Potensi Simpanan Karbon Di Atas Permukaan Tanah Tegakan Acacia Nilotica L. (Willd) Ex. Del. Di Taman Nasional Baluran, Jawa Timur

Acacia nilotica is an invasive species which is difficult to eradicate up to present. A. nilotica is a fast growing species of savanna tree, and therefore is supposed probably to have relatively high biomass and carbon content. The objective of this research was to develop allometric equation of biomass and estimating the carbon storage potential in A. nilotica stand in Baluran National Park. This research used destructive method on 9 sample trees to construct allometric equation. For measuring biomass potency, vegetation analysis was conducted using 3 plots, measuring 100 m x 100 m each on the basis of A nilotica stand density categorization (high, medium, and low). For obtaining data of carbon potency, biomass value was multiplied with 0,47. Research results show that the selected allometric equation for tree total is W=0,34 D1,97 with R2of 98,4. Average biomass potency was as large as 25 tons/ha. Average carbon potency was 11,92 ton/ha. Management of A. niloticain Baluran National Park, in moderate and low density stand can be in the form of clear cutting, whereas high density stand can be maintained for carbon sequestration and utilization by the people community for supplying seeds, livestock feeds, firewood or charcoal briquette

Research on the biomassa, distribution and content of P and Ca nutrients in the soil and biomass was conducted in a primary forest with peat thickness ranging between 2.5 to 6.5 m in the forest concession area (HPH) of PT. Diamond Raya Timber, Bagan Siapi-api, the Riau Province. The objective of the research was to obtain data on the content of P and Ca in the vegetation and peat soil layers at several levels of peat thickness. Research results showed that although vegetation biomass constituted only 6 % of the total biomass of vegetation and peat soil, contain of P nutrient as much as 37 % and Ca 28 % out of the total P or Ca nutrients occurring in vegetation and peat soil. Increasing of peat thickness because the total content of nutrients in the peat soil also increased, although the average content of nutrient per depth interval of 50 cm decreased. Increasing of peat thickness alse increased the content of P or Ca for tree stage vegetation, on the other hand, the content of P or Ca in herbs and shurbs, decreased. This phenomenon shows that on peat thickness more than 3 m only higher vegetation (trees vegetation) could survive properly. Contetnt of P or Ca nutrients occuring at above ground tree stage vegetation reach 64 % and 74 %. While for tree stage vegetation, the biggest nutrient content occurred in branches, nas follows 44 % foer P and 40 % for Ca. Pioneer trees species and lesser known timber in fact had the highest P and Ca elernent concentration. For the highest Ca elements were in timah-timah (Ilex bogoriensis- 14,02 g kg-1), milas (Parastemon urophyllum,13,72 kg-1) and suntai (Palaquium dasyphyllum; 13,13 g kg-1).
