SYNOPSIS Silvicultural factors affecting yield are briefly examined. It is concluded that while many aspects are significantly improving growth and yield, others are depressing them. Positive aspects are tree breeding, site preparation, fertiliser use, weed control, better silviculture and more enlightened management. Negative aspects include pests and

Abstract There is a rapid rate of forest clearance in many tropical countries. This problem is becoming more serious as the rising world population increases demand for fuelwood and timber. The reduced area of forest must be treated so as to produce the highest possible sustained yield of suitable timber compatible with protecting the ...
