Camping impact management at Isle Royale National Park: an evaluation of visitor activity containment policies from the perspective of social conditions Camping impact management at Isle Royale National Park: an evaluation of visitor activity containment policies from the perspective of social conditions
A survey of backcountry and wilderness campsites at Isle Royale National Park reveals that the park?s policies for managing visitor impacts have been remarkably effective in limiting the areal extent of camping-related disturbance. However, the dense spatial arrangement of designated campsites within backcountry campgrounds has also contributed to problems with visitor crowding and...

The role of population monitoring in the management of North American waterfowl The role of population monitoring in the management of North American waterfowl
Despite the effort and expense devoted to large-scale monitoring programs, few existing programs have been designed with specific objectives in mind and few permit strong inferences about the dynamics of monitored systems. The waterfowl population monitoring programs of the U.S. Fish and Wildlife Service, Canadian Wildlife Service and state and provincial agencies provide a nice example...

Habitat management for wintering American Woodcock in the southeastern United States Habitat management for wintering American Woodcock in the southeastern United States
Although much information has been gathered on American woodcock (Scolopax minor) wintering east of the Lower Mississippi Alluvial Valley, that information has not been compiled into a single source assembled for land managers. The objectives of this paper are to pose a few important questions that should be addressed before implementing a land management plan and to briefly review some...

Titanium mineral resources of the western U.S.: An update Titanium mineral resources of the western U.S.: An update
Thirteen deposits or districts in the western U.S. have been examined in which titanium mineral resources have been reported or implied. These deposits are of the following general types (in probable order of importance): 1) Cretaceous shoreline placer deposits, 2) silica-sand deposits of California, 3) fluvial monazite placers of Idaho, 4) anorthosite related deposits, and 5) clay and...

Early avian research at the Savannah River Site, South Carolina: historical highlights and possibilities for the future Early avian research at the Savannah River Site, South Carolina: historical highlights and possibilities for the future
Avian biology and collection of baseline population data was a major part of the first decade (1951-1961) of field research at the Savannah River Site (SRS). Baseline inventories involving organisms and land-use types were part of the mission in the early contracts between the Atomic Energy Commission (now the Department of Energy) and the University of Georgia prior to the establishment...

Epilogue: Lessons yet to be learned Epilogue: Lessons yet to be learned
This chapter provides a summary of the book Ecotoxicology of Amphibians and Reptiles edited by Sparling, Linder and Bishop. In addition to the comparative lack of information on effects and residue burdens of known contaminants in amphibians and reptiles, there is a plethora of new chemicals being produced and released into the environment on which no data exist at all. According to the

Effects of two long-term mowing regimes on vegetation Effects of two long-term mowing regimes on vegetation
Wildlife managers have for many years been interested in the role of mowing as a management technique to benefit wildlife. Two long-term mowing regimes (60 years of similar management) were evaluated at Patuxent Research Refuge during the summer of 1997 to better understand the influence of mowing on vegetation communities. Mowing ceased in 1997 due to reduction in maintenance funds...
