Silvicultural research in Victoria is addressed, aiming: to sustain wood production in second and subsequent rotations of pine plantation; and to balance sustained wood production and ecosystem conservation in native forests. From a review of field trials and fundamental studies motivated by reports of a '2R-decline' in wood production on sandy soils in South Australia, it is concluded that a serious irreversible decline is unlikely to be caused by pines in themselves. It is more likely to be caused by silvicultural practices that compact the soil and, especially in the case of sandy soils, deplete soil organic matter. A reversible decline is most likely to be due to a water x nutrient interaction related to water consumption by weeds and nutrient losses from practices such as slash burning. In native forests, Victoria has embarked upon a major silvicultural investigation: the main issues are the use of the clearfelling silvicultural system, and harvesting of residual wood mainly for wood chipping and conversion to pulp and paper products. Organizational arrangements for the research are described, together with the studies which are based on 3 main systems; namely: the forest ecosystem; the forest management system; and the socioeconomic system. It is concluded that success will require the achievement of high scientific objectivity and strong community involvement.
