Natural abundance of ¹⁵N as a tool for assessing patterns of nitrogen loss from forest ecosystems
… pits at Watershed 5 at the HBEF before and after clear-cutting in order t[delta]test the hypothesis that elevated nitrification and nitrate loss induced by clear-cutting would be associated with a concurrent increase in soil [delta]15 N. A mass-balance model confirmed that increases in …

… 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 negative response are still …

An evaluation of pre- and post-timber harvest water quality in low-order streams in the Missouri Ozarks
… management practices (BMPs) for Regenerative Oak Clear Cutting (ROCC) practice was evaluated on effectiveness to preserve downstream water quality. Fifteen sites, located on MDC lands in Shannon and Reynolds counties in Missouri Ozarks, ranging from 5-50 acres were instrumented with in-stream and …

Effects of Burning and Cutting on Plant Diversity on Ozark Cedar Glades in Stone and Taney County, Missouri
… Ozark Highlands: two control glades, two glades clear cut in 2004 and burned in 2005, two glades clear cut in 2005 and burned in 2006, and two glades clear cut in 2006 and burned in 2007. Five sets of 50m paired transects were used to sample the richness, cover, and ground cover characteristics …

The Role of Breeding Habitat Loss in the Decline of Eastern Whip-Poor-Will (Antrostomus Vociferus) Populations in Canada
… the loss of useable open habitat (e.g., forest clear-cuts, old fields) within 1140 m of Breeding Bird Survey stops predicted the declines in Whip-poor-wills at the same stops. The loss of useable open habitat at stops was primarily caused by forest succession of clear-cuts and old fields; any …

Impact Of Timber Harvest On Mercury Mobilization In A Mixed Pine And Hardwood Forest And Adjacent Lake In Mississippi
… organic matter. This top soil is exposed after clear-cutting and thus more susceptible to runoff. Harvest may also change the net balance between Hg methylation and demethylation by microorganisms through changes in redox conditions and addition of carbon sources from decaying logging residues. …

Suburbia 2124: Re-examining Suburban Development through a Contemporary Lens
… demonstrates man's dominion over nature by clear cutting biodiverse areas, replacing them with impermeable pavements, inefficient buildings, infrastructure that allows stormwater runoff to harm the remaining ecosystems, and a vegetative monoculture. The reality, of which, was only achievable …

Environmental controls on the abundance, diversity, growth, and activity of ammonia-oxidizing microorganisms in temperate forest soils
… performed at Coweeta since the 1930s, including clear-cutting, fertilizing, liming, burning, grazing by cattle, and replanting entire watersheds in white pine. While these treatments were originally imposed to assess the effects of land use on water yield, they have resulted in changes in soil …

Land use change and natural Araucaria forest degradation : northeastern misiones - Argentina
… these forests were strongly exploited and cleared. In only 50 years, of the original existence of A. angustifolia in the Province of Misiones, from about 500.000 individuals before de exploitation, a mere 5% were left in 1992. After the depletion of the araucaria stands a timber industry …

Impact of clearcutting on indigenous mammals of southwest Virginia
… a control (60 to 100-yr-old forest) and 2 clearcuts (a 2-yr-old and 6- to 7-yr-old cut). These areas were located in the Craig Creek watershed of Montgomery and Craig Cos., Virginia. Two growing seasons after clear cutting it was evident that the shrub stratum had not caught up to the uncut …

Structure and function of western red cedar and western hemlock forests on northern Vancouver Island

Hydrological and erosion responses to man-made and natural disturbances : insights from forested catchments in South-central Chile
… Forests at hitherto unprecedented detail. It is clearly the season that controls the hydro-geomorphic work efficiency of clear cutting. Logging, particularly dry seasonal logging, caused a shift of work efficiency towards less flashy and mere but more frequent moderate rainfall-runoff events. The …

Modeling the interactions of forest cutting and climate change on the hydrology, biomass and biogeochemistry of a northeastern forest
… long-term impacts of harvesting practices (e.g., cutting rotation length, intensity) on forest dynamics is a key factor in developing criteria and guidelines for sustainable forest management practices. Process ecosystem models are useful tools to improve predictive understanding of complex, …
