A 50-yr precedent was reversed in 1995 when, following a powerful windstorm, salvage logging was disallowed in the protected Adirondack Park State Forest Preserve of New York, United States. Damage from a similar windstorm in 1950 had provoked massive salvage operations, approved by the New York State legislature on the grounds of fire prevention and resource conservation. Following the 1995 st...

The bird species in western North America that are most restricted to, and therefore most dependent on, severely burned conifer forests during the first years following afire event depend heavily on the abundant standing snags for perch sites, nest sites, and food resources. Thus, it is critical to develop and apply appropriate snag-management guidelines to implement postfire timber harvest ope...

STUDY DESIGN Prospective cohort study. PURPOSE There has been no research examining the use of intraoperative cell salvage during metastatic spinal surgery. The present work is a pilot study investigating the role of cell salvage during metastatic spine surgery. OVERVIEW OF LITERATURE There is no spinal literature about role of cell salvage and autologus transfusion in metastatic spinal can...

Steep terrain harvesting can only be implemented by a limited set of operational alternatives; therefore, it is important to efficient in such conditions, order avoid incurring high costs. Harvesting abiotically-disturbed forests (salvage harvests caused wet snow), which becoming common these days, significantly impact the efficiency extraction operations. This study was evaluate performance tr...

We investigated the effects of postfire salvage logging on cavity-nesting birds by comparing nest densities and patterns of nest reuse over a three-year period in seven logged and eight unlogged patches of mixed-conifer forest in the Blackfoot-Clearwater Wildlife Management Area, Montana. We found 563 active nests of 18 cavity-nesting birds; all species were found nesting in the uncut burned fo...
