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 for Dust deposited on snow cover in the San Juan Mountains, Colorado, 2011-2016: Compositional variability bearing on snow-melt effects

Light-absorbing particles in atmospheric dust deposited on snow cover (dust-on-snow, DOS) diminish albedo and accelerate the timing and rate of snow melt. Identification of these particles and their effects are relevant to snow-radiation modeling and water-resource management. Laboratory-measured reflectance of DOS samples from the San Juan Mountains (USA) were compared with DOS mass loading, part

Data on gall wasp abundance and biomass on valley oak and blue oak trees in California

Gall abundance and biomass was recorded on marked valley oak and blue oak individuals throughout California. Galls, mostly caused by cynipid gall wasps, were identified to species. Sampling effort per tree was recorded as the number of leaves searched for gall wasps. Leaves were taken from two branches per tree using pole pruners, and total galls per tree were summed in each observation. Annual ob

Fecal samples collected in May, August, and October 2014 from Little Book Cliffs Herd Management Area, Colorado, for determination of diet, persistence of DNA in the environment, individual identity, and seed germination.

These data were collected in May, August, and October in west central Colorado from a Bureau of Land Management wild horse herd management area (HMA). Samples were already on the ground, not fresh from the horse. The Diet dataset includes proportion of plant species found in fecal samples using two different lab techniques -- plant DNA bar-coding,and microhistology. Results of both methods to dete

Vegetation measurements of production and offtake in cottonwood communities of the Great Sand Dunes ecosystem, Colorado, 2005-2009.

These data provide measurements of cottonwood production and herbaceous production in cottonwood communities of the Great Sand Dunes National Park ecosystem in the San Luis Valley of Colorado, from 2005-2009. These data also include cottonwood browsing rates. The study area was stratified into 2 ungulate strata: areas with elk and bison herbivory, and areas with just elk herbivory (bison not pres

Body condition score of horses wearing radio collars, weekly behavior data of treatments and controls, and monthly descriptive data of collar and radio tag effects, 2015-2016, Oklahoma, USA

These data are from a study of wild horses and burros wearing radio collars in a captive facility in Oklahoma, USA, for one year. We also evaluated radio transmitter tags (braided into the mane and tails of horses but not burros). We recorded behavior, body condition score, and effects of collars on the necks of horses and burros wearing radio collars and of horses and burros not wearing collars (

Historical and projected production well pumping from January 1, 1900 through March 15, 2141, Middle Rio Grande Basin, Albuquerque and vicinity, New Mexico

This data release contains six historical and projected production well pumping scenarios from January 1, 1900 through March 15, 2141 for the Middle Rio Grande Basin, Albuquerque and vicinity, New Mexico. The production well pumping rates and source of these rates are included as tabular files. Tabular files are also included that define the time period over which these rates are applicable, and t

Argon geochronology data for eastern Bhutan

This dataset accompanies publication 'The influence of foreland structures on hinterland cooling: evaluating the drivers of exhumation in the eastern Bhutan Himalaya'. The Ar/Ar data provides time constraints for the cooling of rocks in the study area.

Demographic data from two chorus frog populations in Colorado

We used 29 years of data on boreal chorus frogs at two sites to view life-history, estimate demographic parameters, assess weather-related covariates, and determine the magnitude of process variation in target parameters. Average estimates of survival probabilities were 0.51 (Standard error [SE]=0.04) and 0.43 (SE=0.04), and average estimates of recruitment probabilities were 0.64 (SE=0.07) and 0.

Data Release for Testing ecosystem accounting in the United States: A case study for the Southeast

Ecosystems benefit people in many ways, but these contributions do not appear in traditional national or corporate accounts so are often left out of policy- and decision-making. Ecosystem accounts, as formalized by the System of Environmental-Economic Accounting Experimental Ecosystem Accounts (SEEA EEA), track the extent and condition of ecosystem assets and the flows of ecosystem services they p

Data release for Influence of multi-decadal land use, irrigation practices and climate on riparian corridors across the Upper Missouri River headwaters basin, Montana

The Upper Missouri River headwaters (UMH) basin (36 400 km2 ) depends on its river corridors to support irrigated agriculture and world-class trout fisheries. We evaluated trends (1984-2016) in riparian wetness, an indicator of the riparian condition, in peak irrigation months (June, July and August) for 158 km2 of riparian area across the basin using the Landsat normalized difference wetness inde

Brown Treesnake visual survey and radiotelemetry data, Guam 2015

The dataset consists of two spreadsheets that contain brown treesnake data (location, perch taxa, perch height, time of detection, whether visible or not, and size of snake) collected during both visual surveys and radio telemetry within a 55-ha enclosure on Guam.

Long term cone production of white spruce throughout boreal forests in North America

Data were compiled on the seed production of white spruce in order to assess the long-term trends in seed production over the past 60 years in North American boreal forests. Data on cone production was merged with annual weather, teleconnection indices such as ENSO, and historical fires in boreal forests.
