Waterfowl Disturbance in California and Nevada (2018) Waterfowl Disturbance in California and Nevada (2018)
Long-term environmental management to prevent waterfowl population declines is informed by ecology, movement behavior and habitat use patterns. Extrinsic factors such as human-induced disturbance can cause behavioral changes which may influence movement, and resource needs, driving variation that affects management efficacy. To better understand the relationship between human-based...
Distribution and Breeding Status of Least Bell’s Vireo Along the San Diego and Tijuana Rivers in San Diego County, California (2020) Distribution and Breeding Status of Least Bell’s Vireo Along the San Diego and Tijuana Rivers in San Diego County, California (2020)
The spatial data results of USGS surveys for Least Bell's Vireo (Vireo bellii pusillus, LBVI) along the Tijuana River and San Diego River in 2020 to determine abundance and distribution of vireos to facilitate population trend analyses and collect information on dispersal and site fidelity of banded vireos as part of long-term demographic studies at multiple sites.
Amphibian chytrid swab data from Mendocino County, California (2016 - 2020) Amphibian chytrid swab data from Mendocino County, California (2016 - 2020)
This dataset includes results from external skin swabbing of Rana boylii and Dicamptodon tenebrosus to test for the fungus Batrachochytrium dendrobatidis from Fox Creek in Mendocino County, California, in 2016-2020. Morphological measurements of swabbed animals were recorded, and Rana boylii had a unique identifier (pit tag) inserted beneath their skin for identification in future...
Global rare earth element occurrence database Global rare earth element occurrence database
This spatial database "usgs_Global_REE.gdb" was created for use in a geographic information system (GIS) to support research on global rare earth deposits and occurrences by the U.S. Geological Survey. This inventory documents the geologic occurrence of rare earths, including mineralogy, type of deposit or occurrence, host rocks and alteration, and any quantitative data related to size...
MODFLOW-NWT groundwater flow model used to evaluate groundwater availability with five forecast scenarios in the Northern High Plains Aquifer in Colorado, Kansas, Nebraska, South Dakota, and Wyoming MODFLOW-NWT groundwater flow model used to evaluate groundwater availability with five forecast scenarios in the Northern High Plains Aquifer in Colorado, Kansas, Nebraska, South Dakota, and Wyoming
This groundwater flow model used a previously developed three-dimensional groundwater flow model (https://doi.org/10.3133/sir20165153) was used to assess future groundwater availability in the Northern High Plains aquifer in Colorado, Kansas, Nebraska, South Dakota, and Wyoming. In this groundwater flow model, a modified version of a previously published soil-water-balance (SWB) model...
Re-Os Geochronologic Data for Porphyry Deposits in the Yukon-Tanana Upland, Eastern Alaska Re-Os Geochronologic Data for Porphyry Deposits in the Yukon-Tanana Upland, Eastern Alaska
Rhenium-osmium (Re-Os) geochronology of molybdenite provides a tool to directly date mineralizing events in hydrothermal systems. In the Yukon-Tanana upland of eastern Alaska, numerous molybdenite-bearing porphyry occurrences are recognized. The deposits are related to middle and Late Cretaceous granitoids (Kreiner and others, 2019; 2020). Some of the porphyry districts have multiple...
Simulation models for buffelgrass and alternative management strategies for Saguaro National Park, AZ Simulation models for buffelgrass and alternative management strategies for Saguaro National Park, AZ
This is a spatially-explicit state-and-transition simulation model of buffelgrass dynamics and alternative management actions in Saguaro National Park, AZ. Buffelgrass is an invasive grass spreading in the park. This work built on previous efforts that first developed a state and transition simulation model linked to FARSITE fire behavior model to describe buffelgrass dynamics in the...
Data and Code for Predicting Flood Damage Probability Across the Conterminous United States Data and Code for Predicting Flood Damage Probability Across the Conterminous United States
This data release contains the associated data described in the related primary publication, "Predicting Flood Damage Probability Across the Conterminous United States" (Collins et al. [2022], see Related External Resources section). Publicly available geospatial datasets and random forest algorithms were used to analyze the spatial distribution and underlying drivers of flood damage...

This data release contains the results from the North American Bat Monitoring Program's report titled 'Status and Trends of North American Bats Summer Occupancy Analysis 2010-2019'. Specifically, these data include tabular data and geospatial data for the species-specific results related to the status and trends of 12 bat species at multiple spatial scales including: 10 km x 10 km grid...
Bridge-Site Study Data for Selected Highway Crossings in Mississippi, 2020 Bridge-Site Study Data for Selected Highway Crossings in Mississippi, 2020
The U.S. Geological Survey (USGS) works closely with the Mississippi Department of Transportation (MDOT) to provide information to be used by the MDOT for design of highway-drainage structures. MDOT spends millions of dollars annually for highway construction. Streamflow records, hydrologic analyses of basins, and hydraulic analyses of flooding potential at proposed highway crossings...
U-Pb and 40Ar/39Ar Geochronologic Data for Selected Rocks from the Western Alaska Range, Alaska U-Pb and 40Ar/39Ar Geochronologic Data for Selected Rocks from the Western Alaska Range, Alaska
This dataset includes four tables with isotopic data and ages for selected igneous bedrock samples collected in 2001 through 2003 from the Western Alaska Range, southcentral Alaska: (1) the concentration of uranium (U) and thorium (Th), ratios of multiple isotopes of lead (Pb) and U, and the age of multiple analytical aliquots, or fractions, of zircon for each sample; (2) the 40Ar/39Ar...
Data on Utah prairie dog body condition and reproductive success, Awapa Plateau, Utah, USA, 2013-2016 Data on Utah prairie dog body condition and reproductive success, Awapa Plateau, Utah, USA, 2013-2016
Data on body condition and reproduction of Utah prairie dogs at 5 colonies on the Awapa Plateau, Utah, USA, June-August 2013-2016. Utah prairie dogs were live-trapped and sampled on 5 colonies. We recorded the age (juvenile/adult) and mass (nearest 5 grams) of each prairie dog and marked its ears and body with metal tags and passive integrated transponders, respectively, for permanent
