Sp678 Forest Management Strategies To Minimize The Impact Of The Gypsy Moth, The University Of Tennessee Agricultural Extension Service
Forestry, Trees, and Timber
Use of silviculture to manage gypsy moth effects gives foresters additional tools for developing integrated pest management programs. Silvicultural actions should be taken prior to gypsy moth outbreaks to reduce or minimize the potential damage that arises in stands vulnerable to gypsy moth. Three approaches to reduce stand susceptibility to gypsy moth are applicable. First, change the stand composition by reducing the proportion of favored species and increasing the number of non-favored species in the stand. This can be accomplished through intermediate thinning treatments. The percentage of favored species that remain should be less than 30 percent of total composition. …

Sp679 Two-Age System And Deferment Harvests, The University Of Tennessee Agricultural Extension Service
Forestry, Trees, and Timber
The two-age system is designed to maintain two distinct age classes in a forest. This system is generally initiated using a deferment harvest, sometimes referred to as a shelterwood or clearcut with reserves (Figure 1). The deferment harvest retains a limited basal area of canopy trees while allowing the majority of the area to regenerate. The harvest initially creates a stand that contains scattered or small groups of older trees, typically one rotation length in age, surrounded by a regenerating age class. The canopy trees that are left are termed reserve trees. At the end of a second rotation length …
Sp673 Forest Certification For Family-Owned Forests - Who Will Certify And Why?, The University Of Tennessee Agricultural Extension Service
Sp673 Forest Certification For Family-Owned Forests - Who Will Certify And Why?, The University Of Tennessee Agricultural Extension Service
Forestry, Trees, and Timber
The concept of forest certification has grown as a tool to foster sustainable forest management. It began on the global scale in the 1980s, and moved rapidly to the United States. Initially in the U.S., several forest product companies completed third-party certification, followed by many publicly owned forests. Some stakeholders are beginning to discuss the need to accelerate forest certification on family-owned forests. Family-owned forests are particularly important in the U.S. because they comprise the majority of the forest land and contribute the greater part of the nation’s annual timber removal. Yet little is known about who among this diverse …
