4 IV. RESULT AND DISCUSSION
The results of this research are based on the expected output. Those are correlation regression equation model and graph of each parameter, total tree
biomass and carbon stock estimated value, and total tree biomass and carbon stock for each forest cover type and whole study area.
4.1 Field Data Measurement
Plots observation were based on the forest cover type as defined by STORMA in the second phase by workshops of 1-9 September 2003 consist of 6
type, these are: Habitat type A, B, C, D, E and F. Forest cover A, B, C and C are natural or primary forest and forest cover type D, E, F are agroforestry system.
The plot observation shows that forest cover A has more closed canopy than the other, because there is no timber extraction. Forest cover type B still has close
canopy, even with the minor extraction of small trees diameter5cm it has no significant influences on canopy layer. Forest cover C has less trees and canopy
layer than A and B due to the timber extraction that reduce trees density inside the plot observation. Forest cover type D, E and F are agro-forestry system that
dominated with cacao, most of the plot observation is cacao plantation with shaded trees inside. The total plots observations are 19 plots located in Toro-
Kulawi district listed in the Table 4.1. The habitat types are considered as the parameter in determining the
vegetation forest type by using stratified systematic random sampling. The type of D, E and F are included in one type as D type agro forestry. These habitat type

will represent the different vegetation grow in the different land condition, topography and rainfall rate.

The habitat types are considered as the parameter in determining the vegetation forest type by using stratified systematic random sampling. The type of
D, E and F are included in one type as D type agro forestry. These habitat type will represent the different vegetation grow in the different land condition,
topography and rainfall rate. The plots distribution over the study area represents the different cover type of A, B, C, D, E and F as figured in Figure 4.1.
The observation result of each forest cover type condition was figured in Figure 4.2 and Figure 4.3. Forest covers A, B and C are natural or primary forest
and forest cover type D, E and F are agro forestry system. Forest cover A has more closed canopy than the other, because there is no timber extraction. Forest
cover B still has closed canopy, even with minor extraction of small tress diameter5cm it has no significant influences on canopy layer. Forest cover C
has less trees and canopy layer than A and B due to the timber extraction that reduce trees density inside the plot observation. Forest cover D, E and F are agro-
forestry system that dominated with cacao, because most of the plot observation is cacao plantation that combined with shaded trees.
