THE EFFECTS OF WHOLE TREE HARVESTING ON SITE HYDROLOGY AND SOIL STRUCTURE AT BEDDGELERT FOREST, N. WALES, UK
… hillslope hydrologies of one forested and one whole tree harvested site. Particular attention was paid to the influence of trees both directly on soil water pathways and indirectly on soil characteristics. Atmospheric inputs were monitored for the slope and individual plots for one year. In …

Effects of Clearcutting with Whole Tree Harvesting on Woody and Herbaceous Plant Diversity After 17-Years of Regrowth in a Southern Appalachian Forest
… the effects of clearcut regeneration with whole-tree harvesting on plant diversity. Three approaches were used to study changes in species composition and structure: (1) forest level, (2) stand level, and (3) diversity indices. Within each approach the forest was stratified into three …

Regional Nutrient Budgets in Forest Soils in a Policy Perspective
… sustainability with different deposition and harvesting scenarios are thus required in policy-making. This thesis deals with the nutrient sustainability regarding nitrogen, calcium, magnesium and potassium on a regional scale in Swedish forests, and the potential effects of forests on carbon …

Even-aged regeneration alternatives for low quality oak hardwood forests in the Virginia Piedmont
… are examined three years after clear felling and whole-tree harvesting upland hardwood stands in the Virginia Piedmont. Natural hardwood regeneration was dominated by stump sprouts, with seedlings and advanced regeneration playing a secondary role. Stump sprouts and seedlings plus advanced …

Soil Carbon, Nutrients, and Phosphorus Fractions: Responses to Weed Control and Harvest Residual Retention in two 10-Year-Old Douglas-fir (Pseudotsuga menziesii) Stands of the Pacific Northwest
Intensive forest management techniques such as whole-tree harvesting and use of herbicides to control weeds can have an effect on nutrient cycling and nutrient pool sizes in the mineral soil. This study was conducted to measure differences in soil carbon (C), nutrient pools, or phosphorus (P) …

Long-Term Effects of Thinning and Prescribed Fire on Tree Growth and Bark Beetle Demography in a Jeffrey Pine Stand
… thinnings implemented with cut-to-length and whole-tree harvesting systems followed by underburning were evaluated for their effects on long-term individual tree and stand level growth responses as well as bark beetle demography in pure, uneven-aged Jeffrey pine (Pinus jeffreyi Grev. & Balf.) …

Spatio-temporal patterns of soil resources following disturbance in a 40-year-old slash pine (pinus elliottii Engelm.) forest in the Coastal Plain of South Carolina
… in response to two types of disturbance: whole-tree harvesting and girdling, and 3) to evaluate some of the current methods for quantifying ecological heterogeneity. In response to both disturbance treatments, spatial heterogeneity measured by sample variance showed a marked "increase and …
