MODEL RELEASED. Silviculture. Inspection of immature fir seedlings at a tree nursery. Silviculture is the cultivation of a tree crop primarily for economic profit. The complete sequence of forest development is subject to a management plan,and the choice of species planted is based on the maximum yield attainable at the site. The rate of deforestation in many areas of the world is such that without the intensive management practices associated with silviculture,it is estimated that timber supplies will become extremely scarce within 25 years. However this kind of forestry has been much criticised for lack of concern for ecological diversity | |
