Riparian vegetation has been recognized for its remarkable environmental and
management implications. Occurred within the dynamic tract of river systems, riparian
vegetation is a complex character that often exposed to the changes of river water and
river beds. Their spatial extent is strongly controlled by inundation and flood
disturbance, which result in the riparian vegetation migration to the point of
destruction, if the competition for the area and other sources are lacking. This paper
presents the findings of collected riparian vegetation information along Sg Johor at the
upstream and downstream of Kota Tinggi. Using Point-Centre-Quarter Method, the
vegetation’s species, density, basal area, diameter at breast height and relative
composition were recorded, identified and classified. Vitex pubescens and Drypetes
spp. dominantly occurred along the upstream and downstream of this river,
respectively. Species like Gymnacranthera bancana, Endospermum malaccense, and
Aquilaria malaccensis are also found inhabit along Sg Johor bank. Classified as woody
vegetation, these vegetations are equipped with buttress roots that enable them to
increase soil strength. This paper also suggests that proper study of riparian vegetation
along river banks could promote a better understanding of the function of each
species, to ensure the sustainability of riparian vegetation as part of river system
engineer.
