Snag density and composition of snag populations on two National Forests in northern Arizona
Snags (standing dead trees) provide important habitat for forest wildlife, as well as a source of coarse woody debris important in forest succession. Because of their importance, some land-management agencies have standards for snag retention on lands under their jurisdiction (e.g. U.S. Forest Service, British Columbia Ministry of Forestry). Despite these guidelines, however, little information...
متن کاملComparison of snag densities among regeneration treatments in mixed pine–hardwood forests
Standing dead trees (snags) are an important component of forest ecosystems, providing foraging, nesting, and roosting substrate for a variety of vertebrates. We examined the effects of four forest regeneration treatments on residual snag density and compared those with densities found in unharvested, naturally regenerated forests (controls) during the second, fourth, and sixth year after timbe...
متن کاملSustainability of the Selection System in Northern Hardwood Forests
The selection silvicultural system is widely recommended for sustainable management of North American cool-temperate tolerant hardwood forests, yet concerns about high-grading, excessive removals, and adequate regeneration persist. We used field measurement of 96 recently harvested stands in the Great Lakes Region of the United States, under corporate, nonindustrial private, and state ownership...

متن کاملExotic European Earthworm Invasion Dynamics in Northern Hardwood Forests of Minnesota, Usa
European earthworms are invading previously worm-free hardwood forests across Minnesota and the Great Lakes region. In many of these forests, earthworm invasions have been associated with the loss of a previously thick forest floor. The ability of earthworms to alter and control ecosystem processes has been demonstrated in agricultural systems, but the dynamics and impact of these invasions in ...
