Struktur dan Komposisi Vegetasi Hutan Semusim Habitat Curik Bali (Leucopsar rothschildi Stresemann, 1912) di Kawasan Labuan Lalang, Taman Nasional Bali Barat

Abstract

ABSTRACT
Vegetation structure and composition of Bali Starling (Leucopsar rothschildi Stresemann,
1912) Habitat at Labuan Lalang monsoon forest, Bali Barat National Park. Research was
conducted in Labuan Lalang monsoon forest, Bali Barat National Park in May 2010 to identify
their vegetation structure and composition of plant species communities in this area. This
information was important as basic data for developing model for habitat reconstruction of
endemic Bali starling birds (Leucopsar rothschildi Stresemann 1912). Several ecological
parameters information such as name species, frequency, density and abundance of individual
species were collected for qualitative an quantitative analyses.
The result showed that 93 species belonging 84 genera and 37 families were found in this area.
Some plant species were recorded as endangered such as Strycnos lingustrina, Helicteres
ixora, Protium javanicum, Rauvolfia serpentina, Zanthoxylum rhetza, Ziziphus rotundifolia,
Ceriops tagal, Flacourtia indica, and Santalum album. The important species that composed
in this forest were dominated by Grewia ericocarpa , Schoutennia ovata (Tiliaceae) and
followed by Vitex trifoliata and Abutilon indicum. The species diversity and evenness index
of Shannon-Wiener indicated that species diversity in this forest were not too high and the
populations on unstable condition. Principal Coordinat Analyses (PCO) on the tree height and
altitude data of every tress showed that tree species associated to Bali starling were found on
the 10 – 25 m tree hiehgt community and occupied in the area of 40 – 60 m asl. The problems and
real condition of the area as the habitat of Bali starling were discussed in this paper.
Key words: vegetation, species diversity, Bali starling, Bali Barat National Park
