Abstract:
The study was done in order to determine and analyze the stand structure of replanted
mangroves and aboveground biomass at 7 year's old replanted mangrove. The physical
characteristic and standing crop biomass of a mangrove forest, sited at the Pulau Layang
Layang at Kelantan Delta, Tumpat were studied. There are two types of mangrove
species; Rhizophora mucronata and Rhizophora apiculata. The R. mucronata trees
dominated in this forest. Five physical characteristics in this study were: diameter (cm),
length (m) (for root and branch only), height (m), distance (m) (for root only), and DBH
(cm) (for stem only). The estimate increment for 7 year's old root was 43 roots. The
increment of length was 1.06 m, the distance was 0.85 m and height of root formation
was 0.66 m. Meanwhile the increment for diameter was dt 1.83 cm, dm 1.98 cm and d,
2.62 cm respectively. Subsequently, the height of tree and DBH estimate increment 5.22
m and 4.44 m. Followed by the diameter of stem formation dt 0.63 cm, dm 3.35 cm and
d10 5.55 cm. The estimate increments for primary branches were 35 branches. The height
and length increment was 2.15 m and 1.4 7 m.
