STRUKTUR DAN KOMPOSISI JENIS HUTAN MANGROVE DI GOLO SEPANG – KECAMATAN BOLENG KABUPATEN MANGGARAI BARAT
Abstrak: This study aimed to
determine mangrove forest structure and composition in Golo Sepang Village,
Manggarai Barat District. Important value index and diversity index value
obtained from mangrove vegetation analysis were used as indicators for
determining mangrove forest structure and diversity. Transect method with
square frame along the line was applied in vegetation analysis. Totally 10
lines and 30 plots were applied for getting types of mangrove, growth
parametersvalue (height and diameter) and others related information. This
study found that the stucture of mangrove consist of 5 familyes with 10
species, namely: Rhizophoraceae (Ceriops tagal (Perr), Rhizophora apiculata
(Bi), R. mucronata Lmk., Bruguiera parviflora (Roxb.), B. sexangula (Lour) dan
B. gymnorrizha (L.) Lamk.), Fabaceae (Derris trifoliata Lour), Meliaceae
(Xylocarpus granatum Koen), Pteridaceae (Acrosthicum aereum Linn) and
Lythraceae (Phempis acidula Forst). R. apiculata (Bi) is the most dominant
species founded in 7 of 10 total sites. Two sites, Sotri and Muara Kiri, have
the highest important value index (300%) for R. Apiculata species. The highest
individual density is found at Sotri site, with value 1.300 tree/hectare, while
the lowest density, 100 trees/hectare is found at Muara Kanan site. In
diversity of mangrove, all sites were categorized as low with highest diversity
index value 1,06.
