The limited success of methods to naturally regenerate northern red oak (Quercus rubra L.) has increased the use of artificial techniques to improve overall oak composition. Enrichment plantings are often recommended as a means to supplement species

A system of stand level and individual tree growth-and-yield models are presented for southern hardwoods. These models were developed from numerous permanent growth-and-yield plots established across 13 states in the US South on 9 site types, in even

Resin flow is the primary means of natural defense against southern pine beetle (Dendroctonus frontalis Zimm.), the most important insect pest of Pinus spp. in the southern United States. As a result, factors affecting resin flow are of interest to r

Yellow-poplar (Liriodendron tulipifera L.) is one of the more commonly regenerated species in upland Piedmont stands following clearcut reproduction methods. Recent studies show that a variety of silvicultural activities affect the growth of yellow-p

Intense competition for growth resources between herbaceous and woody vegetation is considered a major constraint to the growth and development of newly regenerated forest stands. However, very few studies have explored silvicultural opportunities to

Summary Oleoresin flow is an important factor in the resistance of pines to attack by southern pine beetle, Dendroctonus frontalis Zimm., and its associated fungi. Abiotic factors, such as nutrient supply and water relations, have the potential to mo

Despite covering the majority of forestland in the southern United States, hardwoods continue to be grown primarily in natural, extensively managed stands. One reason has been that hardwood growth increases resulting from active management have been

Gmelina arborea Roxb. (gmelina) is a rapidly growing tree, which due to its drought tolerance and excellent wood properties, is emerging as an important plantation species. Perhaps the greatest threat to plantations of this tree is damage due to pest
