Modeling General Response to Silvicultural Treatments in Loblolly Pine Stands
… models incorporating general response to silvicultural treatments for loblolly pine stands were developed using data from various silvicultural experiments across Southern United States. Growth models for treated stands were developed by multiplying base-line growth models with modifier …

Effects of Alternative Silvicultural Treatments on Regeneration in the Southern Appalachians
… of residual trees on regeneration in seven silvicultural treatments. A second study specifically focused on stump sprouting in only three of those treatments. The treatments for first study included: a clearcut, commercial harvest, leave-tree, shelterwood, group selection, midstory …

Vegetation Responses to Seven Silvicultural Treatments in the Southern Appalachians One-Year After Harvesting
The vegetation responses to seven silvicultural treatments one growing season after harvesting were examined on seven sites in the southern Appalachian mountains of Virginia and West Virginia. Treatments included: 1) control, 2) understory control by herbicide, 3) group selection, 4) high-leave …

Impacts of oak-focused silvicultural treatments on the regeneration layer nine years post-treatment in the southern Appalachian Mountains of North Carolina
… between oak and oak competitors in response to silvicultural treatments in the southern Appalachian Mountains of North Carolina. The treatments were: a shelterwood treatment (25-30% basal area reduction through mid-story removal with herbicides), a prescribed fire treatment (two late dormant …

Effects of Silvicultural Treatments and Soil Properties on the Establishment and Productivity of Trees Growing on Mine Soils in the Appalachian Coalfields
… reclaimed pasture land through the use of silvicultural treatments, that mature stands of trees growing on surface mines will respond to treatment similarly to stands growing on native soils, and that mature stands growing on relcaimed surface mines have different soil properties …

Terrestrial Salamanders in southern Appalachain Harwood Forests: Relative Abundance, Nutritional Condition, and Response to Silvicultural Practices
… southwest Virginia and compared the effects of 7 silvicultural treatments on terrestrial salamander richness and relative abundance at 1 site.

Effects of alternative silvicultural practices on oak regeneration in the southern Appalachians
… in oak-dominated stands following five silvicultural treatments was examined on four sites in the mountains of Virginia and West Virginia. Treatments included: silvicultural clearcut, leave-tree, commercial clearcut, shelterwood, and group selection. The effects of harvesting were …

Effects of Timber Harvesting on Terrestrial Salamander Abundance and Behavior
… (1 - 4 years postharvest) effects of 7 silvicultural treatments on terrestrial salamander populations at 4 sites in southwest Virginia and West Virginia. The 3 silvicultural treatments with the most canopy removal (4-7 m2 basal area Shelterwood, Leavetree, Clearcut) had significantly …

Effectiveness of Treatments to Reduce Rhododendron maximum and Promote Tree Seedling Regeneration in the Southern Appalachians
… the forest floor. Past research has shown that silvicultural methods can be used to eradicate R. maximum, however it is unclear which of these methods is most efficient and what effects other than stem mortality may occur. In this study, treatments involving prescribed fire, mechanical cutting, …

Impact of Weed Control and Fertilization on Growth of Eastern White, Loblolly, Shortleaf, and Virginia Pine Plantations in the Virginia Piedmont
… white (Pinus strobus L.) pines to intensive silvicultural practices such as woody competition control and fertilization in the Piedmont Province of Virginia is unclear. To address this issue, during 1999, a mixed stand of Virginia pine and hardwoods was clearcut and site-prepared by herbicide …

Forest Harvesting Disturbance and Site Preparation Effects on Soil Processes and Vegetation in a Young Pine Plantation
… productivity, and to characterize the effects of silvicultural treatments on non-crop vegetation dynamics. Study plots were established on a wet pine flat on South Carolina's lower Coastal Plain. Treatments included a range of 5 disturbance classes (undisturbed, compression tracked, shallowly …

Effects of Forest Regeneration Methods on Salamander Populations in Central Appalachia
… field experiment designed to evaluate a range of silvicultural treatments on biodiversity, I evaluated specific hypotheses related to salamander populations, their prey, and their habitat. First, I examined long-term trends in salamander abundances across a range of silvicultural treatments to …

Development of an inventory system for non-timber functions of forests in the frame of management inventories: the case of Greece
… similar management prescriptions as well as silvicultural treatments could be drawn.

Information privée, attraction conspécifique et sélection d'habitat chez la paruline couronnée (seiurus aurocapilla)
… considered to have a lower impact than other silvicultural treatments, such as clear cutting. However, they can still have an influence on animal populations. In the ovenbird (Seiurus aurocapilla), this treatment often causes a reduction in population densities. Yet, the mechanisms behind this …

Prescribing optimal harvests in forests containing even-aged and uneven-aged stands
… stands, and timing of pre-defined thinning treatments and clearcut harvests for even-aged stands. Recent research results provide various means of numerically deriving optimal management prescriptions for single-stand problems, thus considering all feasible solutions as opposed to …

The influence of silvicultural manipulations on plethodontid salamanders
… relative abundance 30 years after experimental treatments (including clearcut and shelterwood harvests, understory herbicide, uneven-aged management, and an untreated control) were first applied. I found that plethodontid salamander populations in all silvicultural treatments without stand …

Effects of prescribed burning, mechanical and chemical treatments to curtail rhododendron dominance and reduce wildfire fuel loads
… this study was to determine the effects of seven silvicultural treatments on both the fuel loading within an R. maximum thicket and the control of R. maximum as a forest weed. The final objective of the project was to determine the cost effectiveness of each implemented treatment. Due primarily to …

Using economic factors in managing Appalachian hardwoods for high quality
… approach presented allows for economic and silvicultural comparisons of many alternative treatments that need to be considered each time a stand is re-examined for prescription in the progress of a management plan. A decision tree was developed as a systematic way of reviewing the …
