Sedimentation in mangrove promote accumulation of food resources. However, how
mangrove pneumatophores influence sedimentation remain open for investigation. In
this study, the complexity of Rhizophora apiculata’s roots influence the sedimentation
under the root structures and at the walkway area in Pantai Kelanang, Morib were
investigated. The complexity of R. apiculata pneumatophores computationally
analyzed. The sediments composition was measured using wet-sieve method and laser
diffraction method. Correlative analysis shows that no definite pattern between angles
and lengths of R. apiculata roots. Assessment on sediment composition shows
significant differences between walkways and under the roots. High accumulation of
organic matter and sand in samples from under the roots. While the walkway has high
accumulation of clays and silt sediments than others. Mathematical scoring reveals
positive association between root complexities with accumulation of organic matters
and sand in both area. While sand and clay accumulation are inversely associated.
