PENGARUH KERAPATAN AKASIA (ACACIA NILOTICA) (L.) WILLD. EX. DEL. TERHADAP KOMPOSISI DAN KEANEKARAGAMAN TUMBUHAN BAWAH DI TAMAN NASIONAL BALURAN JAWA TIMUR
ABSTRACT: The research was
done in Baluran National Park, Banyuwangi East Java. The objectives of this
research were: to determine of species
composition, importance value of species, diversity index and evenness index,
similarity index, distribution pattern of species, and species association.
This research used the quadrat method. The determination of the species
distribution was calculated using Poisson distribution formula and the
determination of association was calculated using contingency table. The
results of this research indicated that,
there were 61 species of plant
belong to20 familiy. The importance value was between 0,97-55,65%, and species
with high importance value is Brachiaria reptans, Thespesia lanpas, Dichantium
coricosum, and Oplismenus burmanii. The diversity index was between
2,0851-3,4033, and evenness index was between 1,7199-1,9984. The distribution
pattern of species indicated that 38
species were clumped, 10 species
reguler, and 13 species were at random.
The multi-plants tend to have a clumped distribution pattern, and single
plant tend to have a reguler or random distribution pattern. The of association
indicated that 4 species assosiation which the highest index.
