Abstract

The existence of mangrove vegetation in Bangkir Village, Dampal Selatan District, Tolitoli Regency has decreased due to the conversion of mangrove forests into ponds. This study aims to determine the structure and composition of mangrove species in the village of Bangkir. This study uses two methods, namely the qualitative descriptive method through the survey method and the line transect method. Determination of the transect line amounted 1 line and plot placement by purposive sampling amounted to 6 plots. Parameters salinity, pH and soil texture. Data analysis was performed by calculating the relative density, relative frequency and relative dominance to obtain the Importance Value Index (IVI). The results showed that the forest structure consists of three layers, namely layer C and D which are dominated by Avicennia marina, layer E is dominated by Bruguiera cylindrica, while the type Sonneratia alba does not dominate the three layers. The composition the types of constituents are 3 types of mangroves and 3 families. The species that had the highest Importance Value Index (IVI) at all growth stages trees, saplings and seedlings was Avicennia marina and the lowest was Sonneratia alba.

Abstract

Forests are one of the natural resources that have important meaning for human life. Forests with various functions and benefits have a very large influence both directly and indirectly on ecological, economic and social aspects. The purpose of this study was to determine the value of the diversity of plant species that make up the vegetation. This study uses the observation plot/plot method to see the diversity of the types of vegetation constituents in the Protected Forest Area of Uwemanje Village, Kinovaro District. The Important Value Index is used to determine the dominance of one species over another in a stand. Significant values were obtained from the sum of the Relative Density (KR), Relative Frequency (FR) and Relative Dominance (DR) for the level of stakes, piles and trees. The species diversity index was used to determine the species diversity of forest stands. Based on the results of research that has been carried out the types of plants that make up the vegetation in the protected forest area at the tree level found 16 species of trees from 14 families, at the pole level found 16 species from 16 families, at the sapling level found 10 species from 9 families, and at the seedling level found 10 types from 9 families. The level of Species Diversity (H¹) for each level is at the tree level H¹ = 3.81. Pile level H¹ = 3.35. The sapling level H¹ = 3.45 and at the seedling level H¹ = 3.54 belong to the high criteria.Kata Kunci: hutan, vegetasi, keanekaragaman jenis

Abstract

The potential of agrofrestry to sequestrate carbon varies depending on the natural quality of sites and management practices. Agroforestry is a climate change mitigation activities. The aim of study was to estimate the carbon stock of agroforestry system at adjacent buffer zone of Lore Lindu National Park (LLNP). Research was carried out in two types of agroforestry stands (simple and complex) adjacent LLNP buffer zone in Palolo Sub District, Sigi District, Central Sulawesi. Estimation of biomass of tree, herbs, litter, necromass and root was based on an allometric equation. The carbon storage in soil was estimated based on the carbon organic content and bulk density of soil in30 cm of depth. The results of study showed that the total carbon stored in the simple agroforestry (125.97 MgC ha-1) was significantly lower than in the complex agroforestry (209.39 MgC ha-1). In addition, the aboveground carbon stock biomass (tree, herbaceous, necromass and litter) and belowground carbon stock (root and soil organic) in a simple agroforestry were 42.42 MgC ha-1 and 83.55 MgC ha-1, respectively. Whereas, the aboveground carbon stock biomass and belowground carbon stock in the complex agroforestry were 98.46 MgC ha-1 and 110.93 MgC ha-1, respectively. Based on the carbon stock estimation in six agroforestry plots in the buffer zones of Lore Lindu National Park, the complex agroforestry was likely to be more stable and more longer in storing carbon comparedto the simple agroforestry.Keywords: Agroforestry, biomass, carbon, climate change, Lore Lindu National Park
