KEANEKARAGAMAN JENIS TUMBUHAN PAKU-PAKUAN (Pteridophyta) DI DESA BEMBAN KAWASAN HUTAN LINDUNG GUNUNG AMBAWANG KECAMATAN KUBU KABUPATEN KUBU RAYA
Abstract: Research on Fern
Diversity (Pteridophyta) In Bemban village In Mount Ambawang Protected Forest Kubu Kubu Raya District of
West Kalimantan Province was held on September 16 th to October 7 th , 2013.
Sampling plot was taken purposive where there were many fern found. There were
four sampling plot based on height. Plot I located in 50-150 m above sea level
altitude, plot II in 150-250 m above sea level altitude, plot III in 250-350 m
above sea level altitude,and plot IV in 50-150 m above sea level altitude (rubber
plantations). Each sampling plot 40 m x 40 m, divided into 160 subplot 2 m x 5
m aech. There were 13 fern species with 4162 individual these species consist
of 8 terresterial fern with 3799 individual, and 5 epiphytic fern with 813
individuals. The plot at altitude of 50-150 m,were dominated by Lygodium
circinatum and Asplenium nidus, altitude 150-250 m were dominated by
Acrostichum spesiocum and Asplenium nidus, altitude 250-350 m dominated by
Selaginella wildenowii, Asplenium
longisimmum height of 50-150 m asl (rubber plantation) dominated by Nephrolepis biserrata and Asplenium nidus.
The highest diversity index value was at altitude 150-250 m (2,043) which means
the species diversity of ferns were low. Similarity index was highest between
altitude 250-350 m and altitde 50-150 m in rubber plantation,in the value 5,638
%. It means between thw different plot there is no similarity (≤ 25 %).
