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.

Colorado Landcarbon: Accounting for Wildfire Colorado Landcarbon: Accounting for Wildfire
Disturbance disrupts the balance between gross primary productivity and respiration, resulting in a net C loss for some time after a stand-replacing fire. However, our understanding of this process is based on a limited number of studies. Ecosystem C recovery post-fire must be explicitly and carefully examined in order to generate accurate predictions of C cycle impacts of future...
Shapefiles to accompany Colorado Mineral Belt revisited Shapefiles to accompany Colorado Mineral Belt revisited
Although much discussed in the literature, maps showing the detailed outline of the Colorado Mineral Belt are lacking. Lovering and Goddard (1950) show the geology and mines associated with the "Front Range mineral belt" but do not indicate an outline on plates or figures. Tweto and Sims (1963) published the outline of the Colorado mineral belt as page-size illustrations, differing on...
Geologic map of the Strawberry Butte 7.5' quadrangle, Meagher County, Montana Geologic map of the Strawberry Butte 7.5' quadrangle, Meagher County, Montana
The Strawberry Butte quadrangle, scale 1:24,000, is a legacy map of the U.S. Geological Survey, made as part of the Montana Investigations Project to provide information on the stratigraphy, structure, and geologic history of the area. The quadrangle encompasses an area of about 132 km2 (51 mi2) in the southwest part of the Little Belt Mountains and is about 26 km (17 mi) north of White...
Hydrogen stable isotope data for: 'Mechanisms associated with an advance in the timing of seasonal reproduction in an urban songbird'. Hydrogen stable isotope data for: 'Mechanisms associated with an advance in the timing of seasonal reproduction in an urban songbird'.
This dataset includes stable hydrogen isotope values of the nonexchangeable hydrogen contained in the outer most secondary feathers of dark-eyed juncos (Junco hyemalis thurberi) collected from the University of California San Diego campus in La Jolla, California in 2014. Hydrogen isotope values in feathers have become a powerful tool for inferring the breeding grounds of a wide variety...
Data Release for the influence of data characteristics on detecting wetland/stream surface-water connections in the Delmarva Peninsula, Maryland and Delaware Data Release for the influence of data characteristics on detecting wetland/stream surface-water connections in the Delmarva Peninsula, Maryland and Delaware
The datasets were generated for the Upper Choptank River Watershed in Maryland and Delaware. Depressions and the total stream network were derived from a lidar DEM collected during AprilJune 2003 (vertical accuracy root mean square error (RMSE) = 14.3 cm) and MarchApril 2006 (vertical accuracy RMSE = 18.5 cm) for Maryland (1 m resolution) and April 2007 (vertical accuracy RMSE = 18.5 cm)...
OSL methods and field and laboratory data for Mesa Verde soils to support journal article OSL methods and field and laboratory data for Mesa Verde soils to support journal article
Thin loess deposits on the uplands of the southeastern Colorado Plateau have previously not been well studied. We sampled deposits and soils from trenches on Hatch Point mesa near Canyonlands National Park, Utah, and from two outcrops in Mesa Verde National Park, Colorado. At Hatch Point, the oldest buried unit yielded two OSL ages of 10,370 and 7,555 yr; the middle unit yielded 10 OSL...
Dataset: Passive restoration following ungulate removal in a highly disturbed tropical wet forest devoid of native seed dispersers Dataset: Passive restoration following ungulate removal in a highly disturbed tropical wet forest devoid of native seed dispersers
On an island largely devoid of native vertebrate seed dispersers, we monitored forest succession for seven years following ungulate exclusion from a 5-hectare area and adjacent plots with ungulates still present. The study site was in northern Guam on Andersen Air Force Base (1337N, 14451E) and situated on a coralline limestone plateau. We established 22 plots and six 0.25-m2 subplots to...
Results of a U.S. General Public Survey to Inform the 2018 North American Waterfowl Management Plan Update (2017) Results of a U.S. General Public Survey to Inform the 2018 North American Waterfowl Management Plan Update (2017)
This contains data from 1,030 surveys returned in 2017 from across the United States. Data were collected via a mail-out survey stratified by the population of each state. Data collected include nature-related activity participation, attitudes and barriers to hunting and birdwatching, knowledge of others who hunt and birdwatch, preferred birds, involvement in conservation activities...
Sex, length, total mass, fat mass, and specimen condition data for 248 Burmese pythons (Python bivittatus) collected in the Florida Everglades Sex, length, total mass, fat mass, and specimen condition data for 248 Burmese pythons (Python bivittatus) collected in the Florida Everglades
These data were collected from Burmese pythons removed from the Florida everglades as part of invasive-species management. After euthanasia, we sexed (male or female) and measured the snout-vent length (SVL; cm) and total body mass (g) for each python. We also measured total fat mass (g) by removing all visible fat bodies from the coelomic cavity and weighing this mass. For a subset of...
Data Release of the bedrock geology and hydrostratigraphy of the Edwards and Trinity aquifers within the Driftwood and Wimberley 7.5-minute quadrangles, Hays and Comal Counties, Texas Data Release of the bedrock geology and hydrostratigraphy of the Edwards and Trinity aquifers within the Driftwood and Wimberley 7.5-minute quadrangles, Hays and Comal Counties, Texas
The Edwards and Trinity aquifers are major sources of water in south-central Texas and are both classified as major aquifers by the State of Texas. The population in Hays and Comal Counties is rapidly growing, increasing demands on the area's water resources. To help effectively manage the water resources in the area, refined maps and descriptions of the geologic structures and...
Radio telemetry data on nighttime movements of two species of migratory nectar-feeding bats (Leptonycteris) in Hidalgo County, New Mexico, late-summer 2004 and 2005 Radio telemetry data on nighttime movements of two species of migratory nectar-feeding bats (Leptonycteris) in Hidalgo County, New Mexico, late-summer 2004 and 2005
These bat location estimates have been reported by Bogan and others (In press) and come in the form of a GIS shape file. Three species of nectar-feeding phyllostomid bats migrate north from Mexico into deserts of the United States (U.S.) each spring and summer to feed on blooms of columnar cacti and century plants (Agave spp). However, the habitat needs of these important desert...
