Management of remnant tallgrass prairie by grazing or fire in western Minnesota, 2016-2017 Management of remnant tallgrass prairie by grazing or fire in western Minnesota, 2016-2017
We studied the impacts of using cattle grazing or prescribed fire to manage remnant prairies on plant communities and soil characteristics in the prairie parkland province of western Minnesota. These datasets consist of nested frequency plot plant survey data, study site and soil characteristics, and management information taken from 73 sites owned and managed by the U.S. Fish and...
Geochemistry, geochronology, and isotope geochemistry data for zircons and zircon-hosted melt and mineral inclusions in the St. Francois Mountains terrane, Missouri Geochemistry, geochronology, and isotope geochemistry data for zircons and zircon-hosted melt and mineral inclusions in the St. Francois Mountains terrane, Missouri
This dataset contains geochemical, geochronologic, and isotopic data collected for zircons and zircon-hosted melt and mineral inclusions in the St. Francois Mountains terrane, southeast Missouri, USA.
Forests in the Mississippi Alluvial Valley Lacking Sufficient Conservation Protection Forests in the Mississippi Alluvial Valley Lacking Sufficient Conservation Protection
Based on forest patch area, location, and hydrologic influence, we ranked the purported need of forest patches for additional conservation-protection. Qualities for higher ranking included forest patches with & greater than 2000 ha of core-forest that was more than 250 m from an edge, forest patches within high priority areas for reforestation, and forest patches with less propensity for...
Data for the report Ground-water flow and simulated effects of development in Paradise Valley, a basin tributary to the Humboldt River in Humboldt County, Nevada (U.S. Geological Survey Professional Paper 1409-F) Data for the report Ground-water flow and simulated effects of development in Paradise Valley, a basin tributary to the Humboldt River in Humboldt County, Nevada (U.S. Geological Survey Professional Paper 1409-F)
This USGS data release represents the data from the following publication: Prudic, D.E., and Herman, M.E., 1996, Ground-water flow and simulated effects of development in Paradise Valley, a basin tributary to the Humboldt River in Humboldt County, Nevada: U.S. Geological Survey Professional Paper 1409-F, https://doi.org/10.3133/pp1409F.
Glyphosate and aminomethylphosphonic acid (AMPA) in National Water Quality Network Streams and Rivers in the U.S., Water Years 2015-2017 Glyphosate and aminomethylphosphonic acid (AMPA) in National Water Quality Network Streams and Rivers in the U.S., Water Years 2015-2017
The U.S. Geological Survey (USGS) National Water Quality Network - Rivers and Streams (NWQN) is comprised of 110 surface-water monitoring sites designed to track ambient water-quality conditions across the nation. Although numerous constituents, including pesticides, have been collected at many of these sites since 1991, glyphosate and its metabolite aminomethylphosphonic acid (AMPA)...
Pallid Sturgeon Spawning Habitat in the Lower Missouri River Pallid Sturgeon Spawning Habitat in the Lower Missouri River
Lack of reproduction has been hypothesized to be a factor in the decline of the pallid sturgeon (Scaphirhynchus albus) through much of its range. Spawning habitat and behavior have only recently been documented on the Lower Missouri River, which comprises over 1,300 river kilometers of undammed river. This data consists of habitat measurements for ten pallid sturgeon spawning events from...
