Grassland bird habitat has declined substantially in the United States. Remaining grasslands are increasingly fragmented, mostly privately owned, and vary greatly in terms of habitat quality and protection status. A coordinated strategic response for grassland bird conservation is difficult, largely due to the scope and complexity of the problem, further compounded by biological, sociological, and economic uncertainties. We describe the results from a collaborative Structured Decision Making (SDM) workshop focused on linking social and economic drivers of landscape change to grassland bird population outcomes. We identified and evaluated alternative strategies for grassland bird conservation using a series of rapid...

The Prairie Pothole Region spans parts of North and South Dakota, Minnesota, Montana, Iowa and south-central Canada and contains millions of wetlands that provide habitat for breeding and migrating birds. Because it is the continent’s most important breeding area for waterfowl, conservation and management largely focuses on protecting habitat for nesting ducks. However, other wetland-dependent birds also rely on this region, and it is important to understand the degree to which habitat conserved for ducks provides habitat for other species, and how the quality of this habitat will be affected by climate change. Project researchers tested whether waterfowl are effective representatives, or surrogates, for other wetland-dependent...

Proliferation of invasive cattails (for example, Typha x glauca, T. angustifolia) is a concern of wetland managers across the country, and numerous methods have been used to control the spatial extent and density of the plant. To date, however, no single method has proven widely or consistently effective at reducing the long-term growth and spread of these species. We performed a multi-refuge study to evaluate the relative effects of growing-season and dormant-season prescribed burns on cattail production and to gain insight on variables such as soil moisture, groundwater, and biomass that affect the efficacy of burning as a control method. Results indicate total cattail cover recovers to pre-burn levels within...

The Invasion of native communities by cool-season introduced grasses, especially smooth brome and Kentucky bluegrass in upland prairies, reed canary grass in wetlands, is on one of the most important management issues on U.S. Fish and Wildlife Service (Service)-owned lands. Two adaptive management projects, the Native Prairie and Reed Canary Grass Adaptive Management Projects were funded by USGS to examine restoration efforts on NWRs and WMDs in USFWS Regions 3 and 6. This project will support the completion of two decision support tools that are essential to long-term resource management success.

Economic, market-based grassland conservation approaches are needed for expired Conservation Reserve Program (CRP) lands. This proposal describes a new Avoided Grassland Conversion Program that will provide a new private market driver and income stream from private sources for landowners of expired CRP looking for alternative programs to maintain grass cover. An innovative economic alternative to the Conservation Reserve Program will be piloted in portions of the Prairie Pothole Region in 2013, utilizing over $3 million in Federal and private dollars to develop fencing and livestock infrastructure on at-risk of conversion expired CRP lands, requiring an additional $140,000 in financial support to perform necessary...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
