Physicochemical characteristic of mangrove sediment was examined in relation
different age (2-, 7-, 15, 20- and 30-) of managed Rhizophora apiculata (Blume)
stands and approximately 80 years old unmanaged Virgin Jungle Forest in the Matang
Mangrove Forest Reserve, Perak. The sediment exhibit acidic nature (pH 4.7 - 6.2)
with low variation in soil salinity (17.66 – 22.33 ppt). Sediment temperature ranged
from 26.3 to 30.0 º C were influenced by the loss canopy cover due the 30-year
rotation cycle for silviculture management. Significant differences in TOC
concentrations were examined from 2-year to 30-year which indicate the TOC
concentration of sediment in mangrove stands are influenced by the rate of
productivity and rate of decomposition of organic matter. The sediment were sand
dominated with lower composition of mud (silt and clay). The analysis revealed less
variation in physicochemical characteristics of mangrove sediment in relation to
different stand age at Matang.
