Comparison of a large and small grapple skidder in a pine plantation thinning application
… in corridor thinning applications in southern pine plantations. Comparisons included (1) time and production, (2) residual stand damage, (3) soil compaction, (4) cost, and (5) the impact of tree size on productivity. The large grapple skidder was found to be (1) more productive, (2) associated …

Formed by fire : a mountaineering basecamp at the pine plantation in the dystopia of Cecilia Forest
I am a mountaineer. I hike, I climb, I camp (mostly without a tent, unless it snows of course). It has been a serious hobby since I was a Boy Scout at the age of fourteen. At the beginning of the year, I saw an opportunity to add a personal touch through experience and interest in order to better …

Physical and Hydrologic Responses of an Intensively Managed Loblolly Pine Plantation to Forest Harvesting and Site Preparation
The Southeastern Lower Coastal Plain wet pine flats include thousands of acres of jurisdictional wetlands that are economically, socially, and environmentally important. These highly productive forests have been intensively managed as pine plantations for the past few decades. More recently, …

Forest Harvesting Disturbance and Site Preparation Effects on Soil Processes and Vegetation in a Young Pine Plantation
The favorable growth of young loblolly pines (Pinus taeda L.) in response to controlling non-crop vegetation is well documented. However, the beneficial effects of non-crop vegetation on soil quality, nutrient cycling, and biodiversity have not been thoroughly explored. A study was conducted to …

The Effects of Nitrogen and Phosphorus Fertilizer on a Young Loblolly Pine Plantation on Lignite Mine Spoil in East Texas
… were tested in a two year-old loblolly pine plantation on a lignite mine spoil in East Texas. Growth parameters, foliar and spoil nitrogen and phosphorus concentrations were measured after two growing seasons. Nitrogen increased diameter growth during the first year, and foliar nitrogen …

Slash Mulching and Incorporation as Mechanical Site Preparation for Pine Plantation Establishment and Subsequent Effects on Soil Moisture and Site Hydrology
… managed for the production of loblolly pine (Pinus taeda) plantations. These management activities may have adverse effects on soil physical properties, site hydrology, and overall site productivity. Substantial quantities of wood residues are often left on these sites by timber …

Branch, crown, tree and stand water flux in an 180-year-old loblolly pine plantation after thinning, fertilization, and throughfall exclusion treatments
… exclusion treatments on water use by loblolly pine (Pinus taeda L.) trees. Variations in SFD at different radial xylem depths were also examined to improve estimates of tree water use from sap flux density measured in the outer sapwood. This study was conducted in an 18-year-old loblolly pine …

Nitrogen release, tree uptake, and ecosystem retention in a mid-rotation loblolly pine plantation following fertilization with 15N-enriched enhanced efficiency fertilizers
… most frequently limiting nutrient in southern pine plantations. Previous studies found that only 10 to 25% of applied urea fertilizer N is taken up by trees. Enhanced efficiency fertilizers could increase tree uptake efficiency by controlling the release of N and/or stabilize N. Three enhanced …

Tree-Level Forest Monitoring with Artificial Intelligence Using Neural Networks and High-Resolution Imagery
… forest, we can use those measurements to inform plantation management on harvest cycles, we can even use tree measurements to predict climate change. However, for these to occur there needs to be routinely measured and updated forest measurements which can be costly and take a long time to …

Changes in Soil Nitrogen Following Biosolids Application to Loblolly Pine (Pinus Taeda L.) Forest in the Virginia Piedmont
… a common silviculture practices on loblolly pine forest. However, little is known about how biosolids type, application rate, and timing affect forest floor and soil N availability in pine plantations. The objectives of this study were to determine the effect of different types, rates, and …

An investigation, comparison, and development of individual tree competition models
… and tested on data from two young loblolly pine plantation stands. Analyses indicated that, depending on stand, diameter distribution and spatial arrangement, the model acted either as a competition advantage or as a competition disadvantage model. Attempts to discover the nature of the …

The impact of future markets, management regimes, and mechanized harvesting systems on commercial thinning investments in plantations of loblolly pine
… commercial thinning continues to intensify as pine plantation acreage in the south increases. This controversy has caused industrial and nonindustrial landowners to re-examine the economic returns from their plantation investments. This study was undertaken to develop investment guidelines for …

MODELING DIAMETER DISTRIBUTION OF LOBLOLLY PINE PLANTATIONS IN RESPONSE TO MID-ROTATION THINNING TREATMENTS AND ASSING THE ECONOMIC RETURNS IN WESTERN GULF COASTAL PLAIN
… importance in the management of loblolly pine (<em>Pinus taeda</em>) plantations within the Western Gulf Coastal Plain. This study utilized data from a thinning study plots established by the East Texas Pine Plantation Research Project across East Texas and Western Louisiana. A …

Small Mammal Habitat Associations in a Fragmented Agricultural Landscape
… effort was highest for old field and longleaf pine-wiregrass habitats. Pine plantation and upland hardwood habitats yielded the lowest relative abundance per trapping effort. Species showed significant differences in patterns of habitat selection. A principal components analysis (PCA) revealed …

Factors limiting the regeneration of large-seeded hardwoods in the Upper Coastal Plain of South Carolina
… alba L. and Cornus florida L. seedlings in pine plantation understories and adjacent clearcuts. We hypothesized that soil moisture, light, and leaf and stem herbivory would have relatively strong effects on growth and survival during the first two years after planting. Next to each seedling, …

Biology and natural control of the white pine weevil, Pissodes strobi (Peck), in Virginia
… and termination of diapause in the white pine weevil were studied by dissecting weevils at various intervals throughout the winter. Old-generation adults brought into the laboratory November produced viable eggs within 5 days. New generation adults brought into the laboratory on November 4 …

Natural regeneration and ecological succession in Pinus kesiya watershed plantations in northern Thailand : implications on plantation management
Establishment of Pinus kesiya Roy. ex Gord. plantations in Thailand began in the 1960s by the Royal Forest Department. The aim was to reforest abandoned swidden areas and grasslands in order to reduce erosion and to produce timber and fuel wood. Today there are about 150, 000 ha of P. kesiya …

Evaluating the Value of Information Concerning Different Methods of Forest Sampling
… harvest age error. Stands of a thinned loblolly pine plantation in Charlotte State Forest, Virginia were sampled using fixed-radius plots to inform a simulation study. An intensive sample was designated as the true optimal value during the comparison of absolute error values from the sample data. …
