For each tree, the fresh weight by compartment was
obtained at the site using a spring balance. Portions of wood and
bark from stems (lower,middle and top parts) and branches (tip,
medium and bottom parts of branches) as well as foliage (tip,
medium and lower portions of the crown), were collected and
pooled to obtain one composite sample per tissue per tree. All
tissue-types were oven-dried at 70 C to constant weight and
then ground to pass a 0.2 mm sieve for laboratory analysis at the
University of Go¨ ttingen, Germany [2]. Dry/wet weight ratios
from each tree compartment were used to correct the fresh field
weight determinations to obtain biomass per compartment.
