Incorporating Tree Improvement in Natural Regeneration

A large fraction of forest stands in the Eastern United States are naturally regenerated by means of different sivilcultural systems. Although regeneration is a genetic process, limited efforts were made to apply genetic principles in managing naturally regenerated populations. Geneticists have suggested that "dysgenic practices" should be avoided, but it is not clear as to what management practices constitute dysgenic activities. This difficulty originates from the limited knowledge available on genetic consequences of management practices. In this paper, we discuss the means of evaluating the available information, classify biological and cultural factors which needs research, and propose possible organization of research and management capabilities to improve the understanding of the genetic impacts of forest management in natural regeneration.
