Abstract

The forest area of SMBU is the largest conservation forest area in Southeast Sulawesi, located in the Buton archipelago, has many potential of forests that have abundant diversity. However, in line with the development of population andregional development, there has been a disruption to the forest area in the form of illegal logging. This has an impact on the decreasing diversity of forest vegetation in the region. The aim of the study was to analyze species richness and abundance as an indicator of the ecological diversity of forests in the forest area of the SMBU. Plant species measurement data are used to calculate the frequency, density, dominance and importance value index of vegetation, while analyzing the ecological diversity of forest vegetation with the calculation model using the diversity index method, species richness index and similarity index. The results showed that some species had the highest density, frequency and dominance at the tree spesies, namely the Holea (Cleistanthus sp), Redwood (Shorea spp) and Guava (Syzygium spp). At the pole level there are types of Guava (Syzygium spp), and Wukumalampa (Polyalthia lateriflora). While at the saplings level, guava (Syzygium spp) is found. Diversity index values at tree level, pole and saplings can be categorized as having decreased compared to the results of previous studies. The abundance of species shows that there is a tendency for the lower vegetation structure at the level of the pole and saplings to be less abundant. Keywords: forest area, northern buton wildlife reserve, forest structure, ecological diversity, diversity index

Abstract

Water bird diversity in mangrove ecosystem of the Malili District, East Luwu Regency, South Sulawesi, is rarely studied. This reseacrh aims to examine the diversity of bird species in the mangrove ecosystem, Malili District, East Luwu Regency, South Sulawesi. The study was conducted at two stations, namely mangrove forests at the Lakawali River estuary and at the Ussu River estuary. Data collection was carried out using field by field methods, observations were made with binoculars and a Nikon D5200 DSLR camera. Data analysis was performed using the Diversity Index (H’) formula according to Shannon-Winner and evenness index (E) according to Magurren. Species conservation status is determined based on Minister of Environment and Forestry Regulation No. P.106/MENLHK/SETJEN/ KUM.1/12/2018 and IUCN redlist. The results showed that 417 individual birds were found consisting of 5 orders, 7 families and 17 species, there was one protected species, namely great knot (Calidris tenuirostris). The diversity index (H’) in the estuary of Lakawali river is 2.48, and in the estuary of Ussu river is 2.59 which indicates the medium category. The evenness index (E) in the estuary of Lakawali river was 0.92 and in the Ussu River was 0.93 which showed that the distribution of species in both habitats was quite even.
