The silviculture ofPinusplantation establishment in Queensland is site-based. Knowledge of bothPinusgrowth requirements and site capability are used to define site preparation classes (SPCs), the basic planning units used in plantation development. A specific silvicultural system, which incorporates measures for soil conservation and environmental protection, is prescribed for each SPC. The object is to optimisePinusproductivity within the constraints of minimising soil loss and not exceeding a prescribed tolerable soil loss limit.
