Regeneration Harvest (Virginia Department of Forestry)
Several systems are used to harvest and regenerate forest stands. Selection of the system influences the character of the “new” stand. Stands may develop that are even-aged (all trees are essentially the same age), or uneven-aged (trees are many ages, from young seedlings to mature trees and everything in between).

Forestry Leaflets: Thinning Pine Stands (N.C. Forest Service)
When pine trees grow too closely together in thick, dense stands of trees, then the risk of loss from disease, insects and wildfire greatly increases. Thinning reduces these risks and also promotes enhanced tree growth on the remaining higher-quality trees.

Thinning Practices to Improve Forest Health and Tree Vigor (Forestry Webinars)
The benefits of thinning are well documented, but selecting the correct trees can have a profound influence on the success of the thinning treatment. This presentation will review some of the scientific literature that describes how trees will respond to thinning, and what owners and managers might expect as a growth response.

Select Cutting Method of Harvesting Trees (Virginia Department of Forestry)
Select cutting removes the largest and highest quality trees of the most desirable species. It leaves trees that are approximately the same age as those taken, but of no particular value. Since these unwanted trees left standing capture most of the available sunlight and growing space, they prevent high quality stems of more desirable species from becoming established.
