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. The growth salinity level Avicennia marina species has a salinity of 38%, then a pH of 5.14-6.18, the soil texture is a dusty clay substrate, the Sonneratia alba species has a salinity level of 33%, a pH of 5.20-6.62, the texture of clay sand, and Bruguiera cylindrica species have a salinity level of 26%, pH 6.17-7.23, texture of clay substrate.Keywords: Structure, Composition, Mangrove

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

Rattan is a nontimber forest products that can contribute to society in improving household income. Rattan is a climbing plant in the family of Palmae. Rattan grows wild in the forest, and there is also planted by the community. Forest in Indonesia has a high diversity of rattan species, which are about 312 species of rattan growing in the forests of Indonesia. Of the total 13 genera of rattan in the world, 8 genera of which grow in Indonesia. The aim of research to determine the diversity of rattan species in the study site.  This research was conducted for three months, from November 2015 - January 2016 in Lore Lindu National Park area.  This research applied a survey method through using a subjective observation plot (purposive sampling).  This research put on 3 line transects with a length of 1.000 m. the distance between the transect was 100 m. Observation was carried out following the transect line and in the area which found rattan made a plot size of 20 m X 20 m. The number of plots used in this study was 20 plots. The result showed that the number of rattan species in the study site were 7 species of rattan consisting of 57 groves and 214 individuals consisting of 48 individuals of rotan batang (Calamus zollingeri Becc) , 41 individuals of  rotan buku dalam (Calamus shymphysipus Becc), 31 individuals of rotan tumanu (Calamus ornatus var.celebicus Becc), 21 individuals of rotan ibo (Calamus ahliduri Becc), 22 individuals of rotan karuku (Calamus Macrosphaerica Becc), 25 individuals of rotan pai (Calamus coordersianus Becc), and 16 individuals of rotan botol (Daemonorop robusta Warb).
