We used publically available data on duck breeding distribution and recently compiled geospatialdata on upland habitat and environmental conditions to develop a spatially explicitmodel of breeding duck populations across the entire Prairie Pothole Region (PPR). Ourspatial population models were able to identify key areas for duck conservation across thePPR and predict between 62.1 – 79.1% (68.4% avg.) of the variation in duck counts by yearfrom 2002 – 2010. The median difference in observed vs. predicted duck counts at a transectsegment level was 4.6 ducks. Our models are the first seamless spatially explicit modelsof waterfowl abundance across the entire PPR and represent an initial step toward jointconservation...
This project will build a Geographic Information System (GIS) database for the Plains and Prairie Potholes LCC comprised of1) wetland abundance, 2) land cover, 3) primary productivity, and 4) wetness. Ultimately, the database will provide foundational information for future research and will facilitate management and conservation activities for multiple species across the entire LCC.
Rapid expansion of cropland threatens grassland ecosystems across western North America and broad-scaleplanning can be a catalyst motivating individuals and agencies to accelerate conservation. Sprague’s Pipit(Anthus spragueii) is an imperiled grassland songbird whose population has been declining rapidly in recent decades.Here, we present a strategic framework for conservation of pipits and their habitat in the northern GreatPlains.We modeled pipit distribution across its million-km2 breeding range in Canada and the U.S.We describefactors shaping distribution, delineate population cores and assess vulnerability to future grassland losses. Pipitsselected landscapes with a high proportion of continuous grassland...
This data set represents modeled Greater Sage-Grouse (GRSG) Breeding Habitat or Breeding Distribution. Models, built with collaboration from WAFWA, are meant to be used as metrics for subsequent risk analyses and general GIS queries. Modeled data developed by US FWS Kevin Doherty et al. 2015. Model outputs clipped to Current Occupied Range (US FWS 2015). These data were thresholded at 0.65. Values of 1 represent probabilities >= 0.65, while values of 0 represent probabilities < 0.65. GRSG Breeding Habitat models built within Management Zones because wide variation exists in occupied habitats across the range, and risks to sage-grouse vary across Management Zones. Lek data assembled by WAFWA was used to develop...

FY2010In addition to regional Science and Traditional Ecological Knowledge projects that the Great Basin LCC (GBLCC) supports, GBLCC staff lend technical expertise to a range of projects and have contributed to important regional publications on a range of subjects. These publications range in type from textbooks, to management-oriented science and conservation plans, to scientific papers and have covered subjects like wind erosion following fire, soil microbiota response to drought, plant community resilience to invasive species, and alpine plant communities. In many cases these publications form foundations for scientifically-informed management strategies across the Great Basin.

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
