A comprehensive monitoring program for North American shorebirds A comprehensive monitoring program for North American shorebirds
Anthropogenic changes to the biosphere, including widespread degradation and losses of habitats and ecosystems, are causing rapid and profound changes to bird and other wildlife populations throughout the world. Such changes have led to increasing risks and rates of extinction. As a consequence, information on how bird populations are changing is becoming increasingly important to...
Monitoring is not enough: on the need for a model-based approach to migratory bird management Monitoring is not enough: on the need for a model-based approach to migratory bird management
Informed management requires information about system state and about effects of potential management actions on system state. Population monitoring can provide the needed information about system state, as well as information that can be used to investigate effects of management actions. Three methods for investigating effects of management on bird populations are (1) retrospective...

Assessment of freshwater mussels in the Allegheny River at Foxburg, Pennsylvania, 1998 Assessment of freshwater mussels in the Allegheny River at Foxburg, Pennsylvania, 1998
The upper reaches of the Allegheny River are a high-quality resource that supports populations of a number of endangered species. Two endangered species of freshwater mussel, the northern riffleshell, Epioblasma torulosa rangiana, and clubshell, Pleurobema clava, are present in this river reach. Prior to a bridge-replacement project at the Allegheny River at Foxburg, Pa. (river mile 86.2...

Hazards to wildlife from soil-borne cadmium reconsidered Hazards to wildlife from soil-borne cadmium reconsidered
Cadmium is a toxic element that should be included in environmental risk assessments of contaminated soils. This paper argues, however, that hazards to wildlife from cadmium have often been overstated. The literature contains only meager evidence that wild animals have been seriously harmed by cadmium, even at severely contaminated sites. Although some researchers have reported that...

A new national mosaic of state landcover data A new national mosaic of state landcover data
This presentation reviewed current landcover mapping efforts and presented a new preliminary, national mosaic of Gap Analysis Program (GAP) and Multi-Resolution Land Characteristics Consortium (MRLC) landcover data with a discussion of techniques, problems faced, and future refinements.

Combining information from monitoring programs: Complications associated with indices and geographic scale Combining information from monitoring programs: Complications associated with indices and geographic scale
To adequately monitor Neotropical migratory birds, information must be collected to assess population change at local, regional, and continent-wide scales. I suggest that large-scale survey results (such as those derived from the North American Breeding Bird Survey) should not be used to predict population attributes on parks, refuges, and other protected areas. These areas are often...
