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.

Geospatial Route Interface Tool (GRIT) Geospatial Route Interface Tool (GRIT)
The Geospatial Route Interface Tool (GRIT) is a Microsoft Windows desktop, graphical user interface application, written in an open source programming language (Python) that references ESRI Geographic Information System (GIS) python functions. The software streamlines and refines the process of analyzing transportation data and natural resources data, thereby improving the efficiency and
Chemical analyses for arsenic, calcium, chloride, sodium, sulfate, sulfide and dissolved solids, August 2011 through December 2013, from groundwater sampled at or in the vicinity of the San Juan Coal Mine, New Mexico Chemical analyses for arsenic, calcium, chloride, sodium, sulfate, sulfide and dissolved solids, August 2011 through December 2013, from groundwater sampled at or in the vicinity of the San Juan Coal Mine, New Mexico
This data table includes the data source, identifiers for sampled wells, properties in the vicinity of San Juan Coal Mine where wells are located, sampling date, and results of groundwater chemistry analyses for arsenic, calcium, chloride, sodium, sulfate, sulfide and dissolved solids in milligrams per liter.
Genetic and functional connectivity data for greater sage-grouse across the species range generated 2005-2015 (ver. 2.0, December 2022) Genetic and functional connectivity data for greater sage-grouse across the species range generated 2005-2015 (ver. 2.0, December 2022)
Functional connectivity, quantified using landscape genetics, can inform conservation through the identification of factors linking genetic structure to landscape mechanisms. We used breeding habitat metrics, landscape attributes, and indices of grouse abundance, to compare fit between structural connectivity and genetic differentiation within five long-established Sage-Grouse Management...
Indiana Bat fecal DNA study, Indianapolis, IN Summer 2008 Indiana Bat fecal DNA study, Indianapolis, IN Summer 2008
The endangered Indiana bat (Myotis sodalis) has declined dramatically and continuing threats have made it necessary to understand population dynamics and life history throughout the year. Specifically, demographic information (e.g., population size, reproductive success, survival) from the summer range where females raise their young in maternity colonies is difficult to estimate...
Arizona Grasshopper Sparrow nest monitoring data 2011 to 2013 Arizona Grasshopper Sparrow nest monitoring data 2011 to 2013
These data include nest-specific information about Arizona Grasshopper Sparrow nests monitored during 2011 to 2013. The data are formatted as we used them in Program MARK to evaluate factors affecting daily nest survival. Data includes information on when the nest was found, when it was last known to be active, nest fate, and nest age. In addition, we provide vegetation data from the...
Burn severity (2002) and field data (2012) from Tolhuaca National Park (Chile) Burn severity (2002) and field data (2012) from Tolhuaca National Park (Chile)
This data was used in the analysis for the article "Burn Severity Controls on Post-fire Araucaria-Nothofagus Regeneration in the Andean Cordillera" by T. Assal, M. Gonzalez and J. Sibold. The aim of the study was to investigate post-fire regeneration patterns of forests on the west slope of the Andes; to evaluate the relationship between remotely sensed burn severity and forest mortality...
Stable carbon and nitrogen isotope data for: 'Ecotoxicoparasitology of the gastrointestinal tracts of pinnipeds: effect of parasites on bioavailability of total mercury (THg)' Stable carbon and nitrogen isotope data for: 'Ecotoxicoparasitology of the gastrointestinal tracts of pinnipeds: effect of parasites on bioavailability of total mercury (THg)'
Parasites, such as acanthocephalans, cestodes, and some species of nematodes acquire nutrients from the lumen contents within the host gastrointestinal (GI) tract. For ubiquitous toxicants like mercury, both the host species and parasites are potentially exposed. The focus of this study was to determine if there is an effect of parasites on the dietary availability and therefore exposure...
Coal drill hole database for the Little Snake River coal field and Red Desert area, Wyoming Coal drill hole database for the Little Snake River coal field and Red Desert area, Wyoming
The U.S. Geological Survey conducted an assessment of coal resources and reserves in the Little Snake River coal field and Red Desert area of the Greater Green River Basin in Southwest Wyoming. A comprehensive database was compiled to support this assessment that includes data points for drill-holes and measured sections. Associated with these resources are lithology descriptors,...
Geomorphic, climate, streamflow and vegetation data sets to reconstruct channel and vegetation changes associated with the invasion of Russian olive along the Escalante River, Utah 1950-2015. Geomorphic, climate, streamflow and vegetation data sets to reconstruct channel and vegetation changes associated with the invasion of Russian olive along the Escalante River, Utah 1950-2015.
We analyzed historical aerial photography and used dendrochronology to quantify long-term spatial and temporal patterns of narrowing and vegetation expansion, including native cottonwood (Populus fremontii) and non-native Russian olive (Elaeagnus angustifolia), along the largely unregulated Escalante River in Utah, USA. Our general study area was between the town of Escalante and...
Woody riparian invasive plant presence, stem density, and rank dominance and environmental conditions in 2012 at 238 bridge crossings in the Colorado Headwaters, upper/middle Rio Grande, upper Arkansas, and South Platte River Basins, USA Woody riparian invasive plant presence, stem density, and rank dominance and environmental conditions in 2012 at 238 bridge crossings in the Colorado Headwaters, upper/middle Rio Grande, upper Arkansas, and South Platte River Basins, USA
This dataset presents observations and measurements of riparian plant invasion, community composition, and environmental conditions at 238 bridge crossings in four western USA river basins: the Colorado Headwaters, upper/middle Rio Grande, upper Arkansas River, and South Platte River (281,946 square kilometers). The 238 sites are a stratified random sample of all bridge crossings in the...

Isotope and chemical data for: Sulfur isotopes of host strata for Howards Pass (Yukon-Northwest Territories) Zn-Pb deposits implicate anaerobic oxidation of methane not basin stagnation Isotope and chemical data for: Sulfur isotopes of host strata for Howards Pass (Yukon-Northwest Territories) Zn-Pb deposits implicate anaerobic oxidation of methane not basin stagnation
These data consist of sulfur and carbon isotope compositions, concentrations of selected elements, and concentrations of pyrite sulfur and organic carbon in mudstone samples collected from five cores drilled in the Howards Pass district, Yukon-Northwest Territories, Canada. The cores were drilled between 2006 and 2014, site visits and core sampling took place between 2009 and 2016, and...
