Allometric equations were developed and used to estimate standing volume of a l2-year old Rhizophora mucronata Lam. plantation at Gazi bay, Kenya. Twenty two plots, each measuring 10 x 10m2, were established in six belt transects laid perpendicular to the waterline. Fifty trees of diameters varying from 2.5 to 11.5 cm were selected within the plots and harvested. Merchantable volume of the harvested trees was calculated using the Smalian's formula while the nonmerchantable volume was derived from weight-volume conversation ratios. The total stand volume was estimated as 100.4 m3 ha-1 with an annual increment of 8.4 m3 ha-1yr-1 ; giving a biomass expansion factor (BEF) of 2.04 ± 0.74 t m-3. A local volume table based on stem diameter and height was constructed, which allows quick estimation of tree volume.Page Range
