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 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.
