SILVICULTURE
Tending
the forest in the form of climber cutting and liberation thinning is essential because the
overall
stocking of desirable commercial tree species is relatively low.
Every effort is taken to enhance the growth and quality development of
the younger regeneration of these species.
The
infestation of climbing bamboo (Dinochloa
spp.) and other vines are
often severe in logged over forest. This poses a major problem for tree
regeneration, because climbing plants compete with tree seedlings for light and
nutrients. Increased
intensity of light following forest disturbance normally promotes the
proliferation and growth of climbing bamboo and vines.
Tending
involves marking of potential crop trees and competing vegetation such as
non-commercial trees and climbing bamboo, which are subsequently removed by
girdling and cutting operations.
Tending
also allows selecting, among the regeneration, those trees which are preferred as
crop trees. These
two silviculture activities are simultaneously carried out six months after
harvesting operation.
