ANALISIS VEGETASI DI HABITAT ORANGUTAN, STASIUN PENELITIAN KETAMBE, TAMAN NASIONAL GUNUNG LEUSER, ACEH TENGGARA
ABSTRACT: Orangutans occur
in both primary
and ex-logged forests
of Ketambe Research station, Gunung
Leuser National Park,
Aceh. Vegetation analysis
was carried out to
compare the two
habitat types, as
a basis to
understand the ecology
of orangutans in disturbed habitats. Data on 20 plots vegetation analysis 25x25 m
(Juli 2010). The study recorded 275 trees from 99 species in the primary forest
(67 species are food fruit trees), while the ex-logged forest contains 303
trees from 87 species (56 species are food fruit trees). Although the ex-logged
forest still has pioneer species, such as Elateriospermum tapos and
Macaranga sp., the
two habitat types
are not too
dissimilar as shown
by a relatively high index
similarity (ISs = 59,70% for tree and 61% for liana). Diversity index (H’) of
primary forest is also only slightly higher than of ex-logged forest (3,074
versus 2,961). These results
indicate that natural
succession during the last
8 years has been going relatively
well.
