KEANEKARAGAMAN JENIS BURUNG DI KAWASAN LAGOON NUSA DUA, BADUNG, BALI

Abstract

The Lagoon Indonesia Tourism Development Corporation (ITDC) area is a hotel waste management installation located in the Nusa Dua tourism area in the southern part of Bali that is surrounded by mangrove forests. This installation consists of five main ponds, pond 2B and 3 filled with tilapia fish as bioindicators, which attrach various types of birds to this area to forage or other activities. This study aims to determine the species and activities as well as the bird diversity index in the Lagoon area. This research was conducted from January to February 2022. Observations were conducted in the morning and afternoon with six counting points. The bird species encountered were recorded using the ten species recording method. Species identification were based on Mackinnon (2010). The tools used in this study were binoculars, a DSLR camera with a 70-300 mm lens and a Mackinnon field guide. The data obtained were analyzed using Microsoft excel. In this area, 45 species of birds were found with 6 protected species. Bird activities observed in this area include flying, preening, collecting nesting materials and foraging. Foraging activities were the most observed activity in the Lagoon Area. The bird diversity index at the Lagoon ITDC Nusa Dua area is 3.10977 which indicated high diversity, the distribution index is 0.81 which can be said to be almost evenly distributed and the dominance index is 0.087066 which indicate there is no dominant species in the area. The highest percentage of canopy use was observed on the forest floor or stems at 32.01%, and the lowest at 15.10% in the lower canopy.
