Abstract:
Various flora and fauna had disappeared in peat swamp forest before they were recorded,
identified, and utilized. Hence, we conducted vegetation analysis in Kampar Peninsula, Riau.
There were 44 species from 29 families in two-hectare sample plot. The vegetation community was
a regenerating logged-over peat swamp forestand. Shannon-Weiner's Diversity Index for the area
ranged from2.21 to 2.88. Tree density and basal area in plot two (186 stems/ha and 17 m²/ha) was
higher than plot one (127stems/ha and 8 m²/ha). Tree volume and carbon stock in plot two were
(252.19 m³/ha and 100.95 ton/ha)—than they plot one (99.04 m³/ha and 59.75 ton/ha). Syzygium
acutifolium has the highest Important Value Index (IVI) in all growth stages. The tree families
which have high IVI value were Myrtaceae, Dipterocarpaceae, and Sapotaceae. The forest
structure was dominated by tree diameter of less than 20 cm (81%). There were three species that
are listed in the IUCN Red list which were found in the area, namely Shorea uliginosa, Gonystylus
bancanus, and Combretocarpus rotundatus. Based on the forest’s current condition, we suggest
that the policy that regulates logged-over peat swamp forest conversion to acacia plantation or oil
palm plantation to be reviewed.
