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.

Data on separated and dead foals from Conger and Frisco Herd Management Areas, Utah, USA, between 2017 and 2020
We studied factors affecting separation of feral horse foals from their mothers and foal mortality, including variables such as group changes by the mother and behavior of the foal. We include data on feral horse foals that died or were separated, and their siblings. We conducted this study between 2017 and 2020 at two Herd Management Areas (HMAs) in western Utah, USA: Conger and Frisco. We conduc
Isotope analyses (234U/238U, 87Sr/86Sr, δ13C, and δ18O) and U-series disequilibrium ages for speleothem, water, and rock samples associated with Fitton Cave, Buffalo National River, Arkansas, USA
This data release contains tabular data (comma-separated-value files) of natural radiogenic isotopes of strontium, uranium, and thorium for samples of modern water, speleothems, associated with Fitton Cave, north central Arkansas, as well as rock that host the cave deposits. In addition, U-series ages (230Th/U dates and model 234U/238U dates) are calculated from those data for subsamples of speleo
Wyoming Roads (Updated to 2015 Aerial Photography)
A dataset comprised of road centerlines in Wyoming, USA, digitized to 2015 aerial photography from the National Agriculture Imagery Program. This dataset is an update to a former U.S. Geological Survey Data Series (“Large scale Wyoming transportation data: a resource planning tool”: O'Donnell and others, 2014) digitized to 2009 aerial photography. The U.S. Geological Survey Fort Collins Science Ce
Attributed North American Bat Monitoring Program (NABat) 5km x 5km Master Sample and Grid-Based Sampling Frame
This data release contains the North American Bat Monitoring Program (NABat) Master Sampling Grid at the 5 km x 5 km scale with biologically relevant covariates for NABat analyses attributed to each cell of the 5 km x 5 km grid frame for the continental United States. It was created using ArcPro and the 'sf', 'tidyverse', 'dplyr' and 'exactextractr' packages in R to extract covariates from multipl
Thresholded abundance models for three invasive plant species in the United States
We developed habitat suitability models for three invasive plant species: stiltgrass (Microstegium vimineum), sericea lespedeza (Lespedeza cuneata), and privet (Ligustrum sinense). We applied the modeling workflow developed in Young et al. 2020, developing similar models for occurrence data, but also models trained using species locations with percent cover ≥10%, ≥25%, and ≥50%. We chose predictor
Sagebrush structural connectivity yearly and temporal trends based on RCMAP sagebrush products, biome-wide from 1985 to 2020
This dataset includes modeled outputs for structural connectivity and trends in connectivity patterns in the sagebrush biome of the United States at 270-meter resolution. Connectivity was calculated using an omnidirectional circuit-based algorithm, with sources, targets, and conductance based on sagebrush fractional component from the RCMAP sagebrush products for 1985, 1990, 1995, 2000, 2005, 2010
SHRIMP U-Pb and LA-ICPMS U-Pb geochronologic data for igneous and metasedimentary rocks in central Idaho mineral province, U.S.A.
These data are for a geochronologic study of emplacement ages for plutons of the Cretaceous Idaho batholith and detrital zircon ages for metasedimentary rocks, west-central Idaho. Zircon from six samples of discrete plutons across a regional transect were dated by sensitive high resolution ion microprobe (SHRIMP). SHRIMP U-Pb ages of igneous rocks connect the igneous activity to structural history
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 determine the bur
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 species with
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 implemented
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 trees, tw
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 series, “T
