Forestry is the science of understanding to manage forest resources for the benefit of man. Forestry practices to help maintain an adequate supply of wood for timber, plywood, paper, and other wood products. In addition, understanding the value of forestry include managing forest resources such as water, wildlife, grazing areas, and recreational areas.
In general, the forest provides maximum benefit when administered with the goal of providing multiple benefits at once. This concept is called "multiple use forest management" or forest management with multiple benefits. In addition to producing lumber, forests can provide clean water for people, food and shelter for wildlife; land livestock grazing, and recreation for campers, hikers, and picnics.
