Forester Definitions - As defined in Wikepedia...

Forest management includes a range of human interventions that affect forest ecosystems. These activities include both conservation and economic activities, such as extraction of timber, planting and replanting of various species, cutting roads and pathways through forests, and techniques for preventing or making outbreaks of fire.

In developed countries, the environment has increased public awareness of natural resource policy, including forest management.

As a direct result, primary concerns regarding forest management have shifted from the extraction of timber to other forest resources including wildlife, watershed management, and recreation. This shift in public values has also caused many in the public to mistrust resource management professionals.

Wildlife management is the process of keeping certain wildlife populations, including endangered animals, at desirable levels determined by wildlife managers. Wildlife management is interdisciplinary, integrating science, mathematics, imagination, and logic. It deals with protecting endangered and threatened species and subspecies and their habitats, as well as with non-threatened agricultural pests and game species. Aldo Leopold, one of the pioneers of wildlife management, defined it as "the art of making land produce sustained annual crops of wildlife."

Christmas tree cultivation is an agricultural, forestry, and horticultural occupation which involves growing pine, spruce, and fir trees specifically for use as Christmas trees. The first Christmas tree farm was established in 1901, but most consumers continued to obtain their trees from forests until the 1930s and 1940s. Christmas tree farming was once seen only as a viable alternative for low-quality farmland, but that perception has changed within the agriculture industry. For optimum yield and quality, land should be flat or gently rolling and relatively free of debris and undergrowth.

A wide variety of pine and fir species are grown as Christmas trees, although a handful of varieties stand out in popularity. In the United States, Douglas-fir, Scots Pine and Fraser Fir all sell well. Nordmann Fir and Norway Spruce sell well in the United Kingdom, the latter being popular throughout Europe. Like all conifers, Christmas trees are vulnerable to a range of pests. Aphids and adelgids are the most common problems among insect pests, and sudden oak death is a recent development in Californian tree farms. Christmas tree farming has also raised criticism from environmentalists due to the use of pesticides and the possible effects of farming on biodiversity.

The final stage of cultivation, harvesting, is carried out in a number of ways; one of the more popular methods is the pick-your-own tree farm, where customers are allowed to roam the farm, select their tree, and cut it down themselves. Other farmers cultivate potted trees, with balled roots, which can be replanted after Christmas and used again the following year. In the United States, research into Christmas tree genetics has produced better strains of tree seed, which has resulted in higher yields of quality Christmas trees. Jurisdictions in Canada and the United States have established quality grades for cut Christmas trees.

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. Timber often refers to the wood contents of standing, live trees that can be used for lumber or fiber production, although it can also be used to describe sawn lumber whose smallest dimension is not less than 5 inches (12.7 cm).
