BBird Diversity and Distribution Patterns in The Je'neberang River Flow Region, South Sulawesi Gowa Regency

Abstract

The Je'neberang River is a large river that flows from the eastern part of Mount Bawakaraeng and Mount Lompobattang which then goes downstream in the Makassar Strait with a river length of 78.75 km which allows the presence of many wild animals that live around the river. This study aims to determine the diversity and distribution pattern of birds in the Je'neberang watershed as an inventory of bird data. The Point Count method is used in this study where observations are divided into 5 stations from upstream to downstream, at each station, there are 6 observation spots with a distance of 300 m from each spot, with an observation radius of 50 m. The parameters of species diversity used in this research are Shanon Biodiversity, Modified Hill's Ratio Index of Evenness, Dominance Index, and Morisita Index. based on the results of the study found 39 species from 24 families of species Diversity (H') of birds in the Je'neberang watershed with a value of H' at the five stations from 1.95 to 2.67 (1.0 < H' 3.0) meaning moderate diversity. Evenness Index (E') Bird species in the Je'neberang Watershed, Gowa Regency, were classified as unstable with an E value at the five stations, from 0.54 to 0.68. Dominance Index (D) of Bird Species in the Je'neberang River Basin at each observation station, it is known that the five stations have high dominance because the D value at each station is close to 1, which is between 0.80 - 0.89. The distribution pattern of birds in the Je'neberang Watershed is mostly clustered, namely 30 species of birds, 5 species with uniform distribution patterns, and 4 species that cannot be analyzed.
