Lumber or timber is wood in any of its stages from felling through readiness for use as structural material for construction, or wood pulp for paper production. Lumber is supplied either rough or finished. Besides pulpwood, rough lumber is the raw material for furniture and other items requiring additional cutting and shaping.
Forestry is the art and science of tree resources, including plantations and natural stands. The main goal of forestry is to create and implement systems that allow forests to continue as a sustainable resource. The challenge of forestry is to create systems that are socially accepted while sustaining the resource and any other resources that might be affected.
Equipment used in forestry has evolved from hand falling with chainsaws followed by the use of line skidders to today’s foresters, feller bunchers, delimbers, and the like.
