Geographic distribution data were collected based on county level occurrences (or converted from point occurrences to county level occurrences) within the five focal states (Minnesota, North Dakota, South Dakota, Nebraska & Iowa) and each U.S. state or Canadian province bordering those focal states (Wisconsin, Illinois, Missouri, Kansas, Wyoming, & Montana in the USA and Saskatchewan, Ontario & Manitoba in Canada).
Leafy spurge (Euphorbia esula L.; Euphorbiaceae) is a noxious weed accidentally introduced from Eurasia into North America in the late 1800s and early 1900s via multiple shipments of contaminated crop seed. It has spread extensively throughout pasture, rangeland, and natural areas in the Great Plains, inflicting substantial economic and ecological damage. Leafy spurge is unpalatable to most domestic and native ungulates and thus reduces carrying capacity of both rangeland and natural areas. In the four-state region including Montana, North Dakota, South Dakota and Wyoming, costs due to control and reduced forage availability were estimated at $144 million annually. Department of Interior land managers will treat...

The goal of this project is to improve the practice of prairie reconstruction by developing criteria by which success can be measured and related to reconstruction methodology. To achieve this goal, two teams of two botanists will document plant species present on previously reconstructed prairies at two national wildlife refuges, Neal Smith in Iowa and Glacial Ridge in Minnesota. This information will be used to evaluate the methods used on those reconstructions to determine which methods result in relatively greater presence of desirable planted prairie species and less invasion by exotic species. Field work is slated to begin in 2015.

This data set consists of data collected during 2005-2007, 2010, and 2015 at Neal Smith National Wildlife Refuge in Iowa, USA that were used in the analysis in support of the article titled "Toward improving pollinator habitat: Reconstructing prairies with high forb diversity," which has been submitted to Natural Areas Journal. We compared pollinator habitat, in terms of planted forb richness, cover, and phenology, cover of planted grasses, and persistence of exotic species 10-years post-planting of reconstructions with 58 species (extra-high), 34 species (high), 20 species (medium) and 10 species (low) planted at the same time using the same fields, methods, and overall seeding rate. Twelve replicates of three...
This dataset consists of data collected at Badlands National Park (Interior, SD) that were used in the analysis in support of the article titled "Conserving all the pollinators: Variation in probability of pollen transport among insect taxa," which has been submitted to "Natural Areas Journal." Data collected between May-October, 2010 and 2011, and June-July 2012 included insects found in contact with floral reproductive parts of focal plant species, or plant species within a 1 ha plot surrounding focal plant, and pollen species removed from the collected insects' bodies. Focal plant species included Astragalus barrii (May-June 2010-11), Eriogonum visheri (July-August, 2010-11), Chrysothamnus parryi (September-October...

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
