Compare the approaches of a silviculturalist and an economist in considering how best to manage a forest. What are the main concerns of each likely to be? Can their approaches be reconciled?
Answers
Answer:
Silviculture is the art and science of controlling the establishment, growth, composition, health, and quality of forests and woodlands to meet the diverse needs and values of landowners and society such as wildlife habitat, timber, water resources, restoration, and recreation on a sustainable basis. This is accomplished by applying different types of silvicultural treatments such as thinning, harvesting, planting, pruning, prescribed burning and site preparation. Intermediate treatments (thinning) are designed to enhance growth, quality, vigor, and composition of the stand after establishment or regeneration and prior to final harvest. Regeneration treatments (harvesting) are applied to mature stands in order to establish a new age class of trees. Regeneration methods are grouped into four categories: coppice, even-aged, two-aged, and uneven-aged.
All vegetation activities, including prescribed fire, wildlife habitat improvement, timber harvesting and cutting trees in campgrounds for human safety must have a silvicultural prescription. A silvicultural prescription is a document which has a planned series of treatments designed to change current stand structure and composition of a stand to one that meets management goals. The prescription normally considers ecological, economic, and societal objectives and constraints. In the Forest Service, silvicultural prescriptions are prepared or reviewed by a certified silviculturist prior to implementing the project or treatment.
