Abstract

Mangrove memiliki keanekaragaman spesies tumbuhan atau vegetasi yang terdiri dari vegetasi mangrove sejati dan mangrove asosiasi. Penelitian ini bertujuan untuk mengetahui Komposisi spesies tumbuhan mangrove dan keanekaragaman tumbuhan mangrove. Penelitian dilakukan dengan metode kwadrat pada dua stasiun, yaitu stasiun 1 (mangrove alami) dan stasiun 2 (mangrove reboisasi). Komposisi spesies ditentukan dengan indek nilai penting (INP) dan keanekaragaman menggunakan indek diversitas Shanon-Wiener. Hasil penelitian menunjukkan bahwa komposisi jenis mangrove sebanyak 11 jenis, yang terdiri dari 4 jenis adalah mangrove sejati dan 7 spesies mangrove asosiasi. Spesies mangrove yang mendominasi adalah Sonneratia alba (INP=126,16%) dan Rhizophora mucronata (INP=108,18%). Struktur vegetasi terdiri dari tiga kategori yaitu pohon, pancang dan semai. Pada tingkat pohon didominasi oleh Sonneratia alba (INP:175,0%), pada tingkat pancang didominasi oleh Rhizophora mucronata (INP: 191,60%) dan pada tingkat semai didominasi oleh jenis Rhizophora mucronata (INP: 221,76%). Indek keanekaragaman vegetasi sebesar 1,47 dan nilai indek kemerataan sebesar 0,61, hal ini mengindikasikan bahwa kondisi mangrove pada kawasan mangrove di kawasan Kampoeng Kepiting termasuk kategori mantap/stabil.

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.
