SILVICULTURE IS A MEANS to an end, not an end in itself. It is a tool to fulfill the aims of policy, which itself is affected by the economic and social background, by the technological needs of wood-using industries and the general pattern of land usage. Silvicultural techniques based on significant results derived from closely controlled small-scale research must be equally well suited to large-scale application, with its limitations imposed by finance, staff, equipment or infrastructure, before forest management can be expected to adopt them. In a sense, therefore, silviculture is the handmaid of policy, management, utilization and integration of planning and financing. But the coin has two sides. Biological limitations are often the most intractable of all; it is difficult to grow trees in a swamp or a desert. Thus the biological feasibility of an afforestation project, though not the only or even necessarily the most important one, is the most fundamental. Good silviculture is the basis for the success of man-made forests.(Details in following link)
