Trimmed and untrimmed Biomass
The average wood and leaf aliquot moisture contents were 0.61% and
0.53%.Mean trimmed fresh leaf biomass, mean trimmed fresh wood biomass,
mean trimmed dry leaf biomass, mean trimmed wood dry biomass and the
overall mean trimmed dry biomass were 6.02kg, 7.23kg, 3.19kg,4.41kg and
7.60kg respectively. The dry biomass of small untrimmed branches, twigs
and leaves was calculated from the linear regression model developed
between the biomass of trimmed branches, twigs, leaves and the basal
diameter of trimmed branches (equation 1) and accordingly the mean basal
diameter was 7.25cm and the mean untrimmed biomass for small branches
was 9.01kg.

The mean wood density was 0.45 gcm-3while the mean
untrimmed biomass for large branches calculated from the volume of each
section of a branch obtained by Smalian’s formula of a tree was
105.78kg. The mean biomass of trunks was 1543±312kg while the mean DBH,
Height and the mean overall aboveground biomass (AGB) were 69.29±7.97cm,
22.87±0.9m and 1785.12±344kg respectively.
The person’s correlation analysis between above-ground biomass and with
biomass predictor variables (DBH, Height and wood density) showed that
the above-ground biomass was strongly correlated with DBH while Height
is the second important factor correlating with biomass showing moderate
correlation. However, the AGB was not significantly correlated with wood
density (Table 2).
