Data
Staff of USGS Science Centers in Region 7: Upper Colorado Basin collect a wide variety of natural resource data types including spatial, geologic, hydrologic, and biologic. Data included in USGS-series publications that are not publicly available in USGS databases are published in Data Releases. Short descriptions and links to Data Releases produced by Region 7 Science Centers are shown below.

Diet of burros at Lake Pleasant, Arizona and Sinbad, Utah Herd Management Areas in June and July 2019 Diet of burros at Lake Pleasant, Arizona and Sinbad, Utah Herd Management Areas in June and July 2019
We investigated the summer diets of feral burros (Equus asinus) in two ecosystems in which they are found in the United States: a subtropical desert in Arizona (Lake Pleasant Herd Management Area; HMA) and a temperate juniper shrubland in Utah (Sinbad HMA). In June and July of 2019, we gathered 50 burro fecal samples randomly from each location and used plant DNA metabarcoding to...
Predicted 2020 densities for 11 songbird species across the western United States Predicted 2020 densities for 11 songbird species across the western United States
Informed wildlife management requires robust information regarding population status, habitat requirements, and likely responses to changing resource conditions. Growing evidence indicates single species management may inadequately conserve communities and result in undesired effects to non-target species. Thus, management can benefit from habitat relationship information for multiple...
Prioritized sites for conifer removal within the Utah portion of Bird Conservation Region 16, 2020 Prioritized sites for conifer removal within the Utah portion of Bird Conservation Region 16, 2020
Individual species often drive habitat restoration action; however, management under this paradigm may negatively affect non-target species. Prioritization frameworks which explicitly consider benefits to target species while minimizing consequences for non-target species may drastically improve management strategies. We examined extents to which conifer removal, an approach frequently...
Tree-ring widths of Picea engelmannii at Andrews Meadow, Rocky Mountain National Park Tree-ring widths of Picea engelmannii at Andrews Meadow, Rocky Mountain National Park
Andrews Meadow in the Loch Vale watershed, Rocky Mountain National Park. Sample Collection: Englemann spruce (Picea engelmannii) living on slopes surrounding and at the edge of Andrews meadow (Latitude 40˚ 17’ 24” N, Longitude 105˚ 40’ 01” W NAD83). At the time of collection, the climate-sensitive upland P. engelmannii trees were growing on well-drained slopes above the meadow. Seventeen...
Digital database of structure contour and isopach maps of multiple subsurface units, Michigan and Illinois Basins, USA Digital database of structure contour and isopach maps of multiple subsurface units, Michigan and Illinois Basins, USA
This digital data release presents contour data from multiple subsurface geologic horizons as presented in previously published summaries of the regional subsurface configuration of the Michigan and Illinois Basins. The original maps that served as the source of the digital data within this geodatabase are from the Geological Society of America’s Decade of North American Geology project...
grsg_lekdb: Compiling and standardizing greater sage-grouse lek databases, version 1.2.0 grsg_lekdb: Compiling and standardizing greater sage-grouse lek databases, version 1.2.0
Greater sage-grouse (Centrocercus urophasianus; hereafter referred to as sage-grouse) are landscape-scale sagebrush obligate species and an important gamebird and iconic species of the West (Hanser & Knick, 2011; Rowland et al., 2006). They occupy the sagebrush biome in western North America, extending east of the Sierra Nevada/Cascade Mountain ranges to the western regions of the Great...
Geochronologic and isotopic data for Paleohydrologic history of Pluvial Lake San Agustin, New Mexico Geochronologic and isotopic data for Paleohydrologic history of Pluvial Lake San Agustin, New Mexico
This dataset includes tables of radiocarbon, uranium thorium series, and luminescence geochronologic ages and stable carbon and oxygen isotope compositions for sedimentary and organic samples.
Digital hydrogeologic framework model of the Upper Colorado River Basin, western U.S. Digital hydrogeologic framework model of the Upper Colorado River Basin, western U.S.
This digital dataset was created as part of a U.S. Geological Survey hydrologic resource assessment and development of an integrated numerical hydrologic model of the hydrologic system of the Upper Colorado River Basin, an extensive region covering approximately 412,000 square kilometers in five states: Wyoming, Colorado, Utah, Arizona, and New Mexico. As part of this larger study, the...
Data on long-term flea control using fipronil grain bait with black-tailed prairie dogs, South Dakota, 2020-2022 Data on long-term flea control using fipronil grain bait with black-tailed prairie dogs, South Dakota, 2020-2022
We collected fleas from black-tailed prairie dogs (Cynomys ludovicianus) on Buffalo Gap National Grassland and Badlands National Park, South Dakota, 2020-2022. We anesthetized trapped prairie dogs (and their fleas) with isoflurane in induction chambers for processing. We combed each individual with a fine-tooth comb for 30 seconds to remove and count fleas. We released all animals, after...
Data on flea combing removals from black-tailed prairie dogs, Vermejo Park Ranch, New Mexico, 2011 Data on flea combing removals from black-tailed prairie dogs, Vermejo Park Ranch, New Mexico, 2011
We studied black-tailed prairie dogs and their fleas in the short-grass prairie of Vermejo Park Ranch, New Mexico, USA, June-August 2011. We live-trapped and sampled prairie dogs on 20 plots at 13 prairie dog colonies. Upon capture, we anesthetized each prairie dog (and its fleas) with isoflurane and combed the prairie dog as thoroughly as possible for ectoparasites (as described below)...
Data on flea larvae survival following exposure to black-tailed prairie dog scat, 2016-2018 Data on flea larvae survival following exposure to black-tailed prairie dog scat, 2016-2018
We collected fecal pellets from six black-tailed prairie dogs in captivity. Prairie dogs were provided free access to non-treated grain (oat groats) or fipronil-treated grain for 5 days. Two prairie dogs received non-treated grain and four prairie dogs received fipronil grain. During each day of the feeding trial, prairie dog fecal pellets were collected, stored in sealable plastic bags...
Data on flea control using FipBit fipronil bait pellets with black-tailed prairie dogs, South Dakota, 2020-2021 Data on flea control using FipBit fipronil bait pellets with black-tailed prairie dogs, South Dakota, 2020-2021
We live-trapped black-tailed prairie dogs on Buffalo Gap National Grassland, South Dakota, 2020-2021. We anesthetized trapped animals (and their fleas) with isoflurane in induction chambers for processing. We combed each individual with a fine-tooth comb for 30 seconds to remove and count fleas. The total flea count from an individual prairie dog was considered an index of flea abundance...
