Airborne lidar (Light Detection And Ranging) is a proven technology that can be used to accurately assess aboveground forest biomass and bio-energy feedstocks. The overall goal of this study was to develop a method for assessing aboveground biomass and component biomass for individual trees using airborne lidar data in forest settings typical for loblolly pine stands (Pinus taeda L.) in the sou...

Intensive management of pine plantations in the southeastern coastal plain typically involves weed and pest control, and the addition of fertilizer to meet the high nutrient demand of rapidly growing pines. In this study we coupled a mechanistic nutrient uptake model (SSAND, soil supply and nutrient demand) with a genetic algorithm (GA) in order to estimate the minimum addition of phosphorus ne...

In 1991, a series of experiments was initiated to examine the effectiveness and research value of inoculating 6-week-old seedlings of slash (Pinus ellionii var. ellionii) and loblolly pine (I’. raeda) with suspensions of basidiospores of Cronartium quercuum f. sp. fusiforme onto wounds made by severing the upper approximately 1 cm of the stems. These experiments were to evaluate the wound techn...

Forests provide goods and services to society and, often, refugia for plants and animals; forest managers utilize silviculture to provide ecosystem services and to create habitat. On the Coastal Plain of North Carolina, forest management objectives typically include wood fiber production but may also include the maintenance of environmental quality and, sometimes, species diversity. Silvicultur...

Calculating stand biomass potential is an increasingly important aspect of silviculture, particularly when attempting to restore forest ecosystems or determining additionality in sequestered carbon. However, the lumbering of the original forests of the Midsouth region of the United States of America, coupled with the accelerating conversion of unmanaged natural-origin stands to loblolly pine (P...

Cutover pine-hardwood s i t es in the Piedmont of central Georgia were prepared by prescribed burning or drum chopping and regenerated to loblolly pine (Pinus taeda L.) by planting or directseeding. Site preparation had Little effect on soil physical properties. After an average of 12 years, trees were larger in dbh and total height, the merchantable stand was greater, and distribution was more...

Fusarium circinatum causes pine pitch canker (PPC) disease and associated symptoms such as resinous lesions, mechanical weakness, crown dieback that may lead to mortality in Pinus Pseudotsuga spp. There are no ameliorative techniques available for the disease, genetic resistance among populations support commercial plantation deployment has not been well characterized. In this study, we charact...
