Abstract
Cull trees and undesirable species may occupy a high percentage of forest growing space. In a managed forest, these unwanted individuals must be cut or killed so that sound vigorous growing stock of good species can utilize the space. The methods most frequently used to eliminate medium to large-size trees from timber stands are either girdling or application of herbicides in notches or in frills.
