Decision-support tool for managing endangered species in the face of uncertainty

Along the Santa Clara River in California, populations of the federally and state-listed Least Bell's Vireo (Vireo bellii pusillus) are recovering from near extirpation. Habitat protection and restoration, as well as reducing brood parasitism by Brown-headed Cowbirds (...

Common Loon Migration Study

Common loons often migrate several hundred miles to reach coastal waters during fall migration. Information about this part of the loon's life history is not well known.

The use of satellite telemetry allows biologists to track loon movements through distant migrations and during winter. A transmitter attached to a radiomarked loon periodically sends a signal which is detected by a...

Great Lakes Restoration Initiative (GLRI)

The President's 2010 Budget provided $475 million for a new interagency Great Lakes restoration initiative, which targets the most significant problems in the region, including invasive aquatic species (like zebra and quagga mussels), non-point source pollution, and contaminated sediment.

This initiative uses outcome-oriented performance...

U.S. Fish & Wildlife Service - Automated Waterfowl Counts

The Upper Mississippi River System (UMRS) is an important stopover point for waterfowl during early-spring and late-fall migrations, particularly portions of the river between the Navigation Pools 4 and 13.This part of the Upper Mississippi River contains large areas of aquatic vegetation that include preferred food sources such as Arrowhead and Wild Celery. In addition, many of these areas...

Waterbird Distribution and Foraging Patterns on the Great Lakes with Respect to Avian Botulism

The Upper Midwest Environmental Sciences Center (UMESC) in La Crosse, Wisconsin is studying the distribution and foraging patterns of sentinel fish-eating waterbirds through aerial surveys, and by tracking migration movements coupled with foraging depth profiles of common loons equipped with archival geo-locator tags and satellite transmitters. The results of this work are expected to...

Boater Compliance with Established Voluntary Waterfowl Avoidance Areas on the Upper Mississippi River

Disturbance to resting and feeding waterfowl on the Upper Mississippi River National Wildlife and Fish Refuge (Refuge) is of utmost concern to refuge managers. Voluntary Waterfowl Avoidance Areas (VWAA) have been established to reduce boating disturbance to migratory waterfowl on Navigation Pools 7 and 8 of the Upper Mississippi River.  Ongoing boater compliance with the VWAA programs has been...

Species Distributional Modeling and Spatial Patterns in Genetic Introgression: the Case of Golden-winged Warblers and Blue-winged Warblers

The Golden-winged Warbler (Vermivora chrysoptera) is a species of considerable conservation concern in North America, primarily due to widespread population declines attributable to habitat loss (Confer et al. 1992, Buehler et al. ) and displacement by the Blue-winged Warbler (V. pinus) in areas of sympatry (Gill 1980, 2004; Will 1986).  Recent research highlighted an important mechanism in...

Assessing the Potential for Climate Change Impacts on the Suitability of Inland Glacial Lakes for Lake-Dependent Biota in the Great Lakes Region

Climate change models predict warmer temperatures, changes to precipitation patterns, and increased evapotranspiration in the Great Lakes region. Such climatic changes have altered, and are expected to further alter hydrological, chemical, and physical properties of inland lakes. Lake-dependent wildlife are often sensitive to changes in water quality, and are particularly susceptible to lake...

Evaluating Habitat Use by Pelagic Birds on the Western Great Lakes, and Airspace Use of Migrant Songbirds Near and Over the Western Great Lakes.

This assessment deals with a select geographic area, the Upper Great Lakes, and the common birds that can be found there during migration periods. Much is known about potential landbird stopover habitats and raptor migration routes, and a great deal of GIS data is available to develop preliminary risk models for landbirds. However, the distribution, abundance and species composition of...

Evaluating the Possible Effects of Wind Power Development on Refuging Waterbirds in the Great Plains, Upper Midwest and East Front of Northern Rocky Mountains

We will address the question of whether wind farms can be built near refuges for large concentrations of waterbirds and not cause mortality or critical habitat avoidance. Much is known about many waterbirds (waterfowl, cranes, shorebirds and others) and the places where they concentrate (refuge) during migration. The primary areas of uncertainty in placing wind turbines in relation to the...

Decision Support Partnership for Assessing Bird Movements and Habitat Use in Interior Landscapes and the Upper Great Lakes

Wind energy development is emerging as one of the major controversial issues facing migratory bird management, especially in light of the public’s growing perception of wind energy’s potential detrimental effects on birds, and the rapid growth of the industry. Three DOI bureaus, the Fish and Wildlife Service, Geological Survey, and National Park Service, have recently recommended that research...
