Department of Interior the Natural Resource Conservation Achievement Award for FY19-20 for efforts associated with the Monarch Conservation Science Partnership
Congratulations to the Monarch Conservation Science Partnership for receiving a 2020 Department of the Interior Natural Resource Conservation Achievement Award. The Team received this award in the Trailblazer category for efforts to address concerns related to the Monarch butterfly including conducting extinction risk research to establish the minimum overwintering population size required to...
Developing a Pre-Event Planning Tool for Modified Unified Method Fishing Events (Web Application)
The USGS is adapting the Chinese Unified Method, a fishing harvest method that uses herding techniques and a variety of nets to drive fish and concentrate them into a concentrated area for capture, in the fight against invasive Asian carps. This “Modified Unified Method” incorporates adapted techniques and modern technology for efficient, mass removal of bigheaded carp in North American waters...
Development of Chemical Tools to Control Invasive Carp and Dreissenid Mussels
Over 180 and 140 aquatic invasive species (AIS) have been introduced into the Great Lakes and Upper Mississippi River basins, respectively, with threats of new invasions always on the horizon. Sea lamprey, zebra mussels, and invasive carps are just a few examples of AIS whose abilities to alter aquatic habitats and disrupt food cycles threaten many outdoor recreation opportunities and ecosystems...
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 goals and measures to target the most significant problems...
Distribution and Controls Over Habitat and Food Web Structures and Processes in Great Lakes Estuaries
Rivermouth ecosystems, or freshwater estuaries, are the focus of human and wildlife interactions with the Great Lakes. They are highly valued as the region’s urban, industrial, shipping and recreational centers; and home to recreational harbors, wildlife viewing and production, beaches and urban riverfronts. Rivermouths are also both the mixing zones where nutrients from upstream watersheds are...
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 elucidate...
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 waterbirds...
Monarch Conservation Science Partnership
The Challenge Over the last two decades, the Eastern migratory population of monarch butterflies has declined by about 80%, leading many scientists to consider how to best conserve and rebuild monarch populations. Conservation efforts can be challenging to design and execute because of the multi-generational migration of monarchs that spans North America. Conservationists must consider many...
Amphibian Research and Monitoring Initiative: Midwest Region
Populations of amphibians have been declining around the world (Stokstad 2004). The US Geological Survey is working to understand the extent and causes of such declines via the Amphibian Research and Monitoring Initiative (ARMI). We are conducting research in support of this program in the Midwest Region of ARMI. Our offices and laboratories are at the Upper Midwest Environmental Sciences Center...
Birds as Indicators of Contaminant Exposure in the Great Lakes
Objectives: 1. Use tree swallows and colonial waterbirds in the Great Lakes to evaluate contaminant Exposure (geographic and spatial) 2. Trends through time (temporal) 3. Effects (reproductive, physiological, genetic) 4. Monitor cleanup actions
