MANGROVE COMMUNITY STRUCTURE AT MANGROVE ECOTOURISM AREA IN KAYU ARA PERMAI VILLAGE, SIAK REGENCY

Abstract

This research was conducted on July - August, 2020 in mangrove ecotourism area of
Kampung Kayu Ara Permai, Siak Regency. The purpose of this study was to obtain the
value of density, frequency, mangrove important value index (INP Mangrove),
dominance index value and mangrove diversity index in the mangrove ecotourism area
of Kampung Kayu Ara Permai. Five serial plots with provisions of 10x10 meters
2
for
2
trees, 5x5 meters
for shrubs, and 2x2 meters
2
for seedlings. Each plot identified species,
measured stem diameter, and the number of individual mangroves. Vegetation analysis
using Mueller and Dumbois formulas to get the value of diversity, frequency, dominance
and importance of plants. The results showed that nine species of mangrove vegetation
were found: Avicennia alba, Avicennia marina, Bruguiera gymnoriza, Bruguiera
sexangula, Bruguiera sylindrica, Lumnitzera littorea, Rhizophora apiculata, Rhizophora
mucronata, and Rhizophora stylosa. The highest importance index was found in
Rhizophora apiculata (102.4%). Mangrove diversity in this area is high (5.28) and is
dominated by Rhizophora apiculata. The high diversity of mangroves is due to the
preservation of this area by community groups.
