Because edges provide easy access to more than one habitat, they usually have more diverse wildlife communities than large blocks of a single habitat.A clearcut harvest will produce a mixture of pulpwood and sawtimber products for the forest products industry based on the size of the trees and whether the trees are softwood (pine) or hardwood (maple, oaks, etc.).Harvesting Trees In forest management, trees are harvested for a variety of reasons including improving the health of the forest; controlling the types of trees that grow on the site; attracting certain wildlife species; providing a source of income for the landowner; producing paper, lumber and numerous other forest products; and improving access to the area for hikers, hunters and other recreational users.

Shelterwood Harvest In a shelterwood cut, mature trees are removed in two or three harvests over a period of 10 to 15 years.
This method allows regeneration of medium to low shade-tolerant species because a “shelter” is left to protect them.
To improve the health and productivity of the forest, forest managers may remove a portion of the trees in the early stages (10-15 years) of a growing stand of trees so there is less competition for sunlight, water and nutrients.
The forest is ‘thinned’ by taking out a certain percentage of the trees.
Another disadvantage to shelterwood cuts is that they require more roads to be built through the forest, and increase the risk of soil disturbance and damage to the remaining trees during harvesting.
Seed Tree Harvest In a seed tree harvest, five or more scattered trees per acre are left in the harvested area to provide seeds for a new forest stand.
Forests are an important part of our state’s environment and economy.
When they are well managed, forests provide clean air and water, homes for wildlife, beautiful scenery, places for recreation and more than 5,000 products we all use every day.
Thinning Harvest When trees are crowded together, they are in greater competition for sunlight, nutrients and water.
As a result, they tend to be less healthy and to grow less vigorously.
