Riparian vegetation, topography, and sediment quality along the Lower Virgin River 2010-2021 (ver. 2.0, January 2025)
Note: This data release has been preceded by version 1.0, available here: https://doi.org/10.5066/P97KZJGP. The data release presents observations of riparian vegetation, topography, and sediment quality in five river reaches of the Lower Virgin River extending downstream 62 river kilometers (rkm), from near the town of Littlefield (Arizona) to approximately 15 rkm upstream from the...
Percent volumes of insects consumed by the western small-footed bat (Myotis ciliolabrum) captured at Chaco Culture National Historical Park, El Malpais National Monument and El Malpais National Conservation Area, Mesa Verde National Park, Pecos National H
This dataset represents the date and related identification number for each guano sample collected from the western small-footed bat (Myotis ciliolabrum) captured at Chaco Culture National Historical Park, El Malpais National Monument and El Malpais National Conservation Area, Mesa Verde National Park, Pecos National Historical Park, Guadalupe Mountains National Park, and Capulin Volcano...
Current linear fuel breaks in the sagebrush biome of the western United States (2020) attributed with relevant environmental variables
Unprecedented wildfire frequency fueled by invasive annual grasses threatens sagebrush habitats. To suppress fire and conserve sagebrush, land management agencies have installed ~10,000 km of fuel breaks across the sagebrush ecosystem. The ecological risks and benefits of creating fuel breaks for wildfire suppression are unquantified but must be balanced to avoid accelerating sagebrush...
Vegetation cover from a precipitation manipulation experiment at the Spruce Gulch Wildlife and Research Preserve, Colorado
These data consist of plot-level plant species cover measurements from a precipitation manipulation experiment located in the Spruce Gulch Wildlife and Research Reserve near Boulder, Colorado. This data release consists of absolute percent live foliar cover measurements of all plant species within each plot for the years 2011, 2012, 2013, 2020, 2021, 2022, and 2023. From 2011-2013, plots...
Data on flea larvae survival following exposure to black-footed ferret scat
We collected fecal scat pellets from 4 black-footed ferrets (Mustela nigripes) in captivity. The ferrets were fed black-tailed prairie dogs (Cynomys ludovicianus) that had previously consumed 0.005% fipronil grain. Fipronil is an insecticide from the phenylpyrazole chemical family. Specifically, ferrets were fed portions of three prairie dogs (60-80 g/day) for one week. We collected scat...
Field Notebooks from Loch Vale watershed, Rocky Mountain National Park, research from 1981 through 2023
These files consist of scanned field notebooks from long-term research and monitoring conducted in the Loch Vale watershed, Rocky Mountain National Park from June 17, 1981, through September 19, 2023. There are 72 individual PDF files. They are accompanied by a spreadsheet that serves as a pointer to the contents of each notebook, including the range of years in each, start and end dates...
Summary of Responses at the 2021 Colorado River Basin Science and Technology Meetings
In June and July 2021, the Colorado River Basin Actionable and Strategic Integrated Science and Technology (ASIST) pilot team held a series of 12 Science and Technology Collaboration meetings with U.S. Geological Survey science staff to discuss complex integrated science challenges and solutions related to drought in the Colorado River Basin. These meetings were structured to explore...
Modeled habitat suitability for Erigeron rhizomatus (Zuni fleabane)
This raster presents the final outputs from a VisTrails/SAHM workflow to model the potential distribution of Zuni fleabane (Erigeron rhizomatus) in northwestern New Mexico. These models utilized field data of spatially thinned occurrence locations and random background locations. We included a suite of predictors related to soils, topography, vegetation cover, and geology. Details about...
Rates of change in invasive annual grass cover to inform potential management opportunities across the sagebrush biome of the western United States
We used Rangeland Condition Monitoring Assessment and Projection (RCMAP) maps of annual herbaceous fractional components (mostly invasive annual grasses) to calculate mean rate of change in invasive annual grass cover over five-year time periods (ratesOfChange1987_2021.zip). We also created a map that identifies zones of the sagebrush biome that could be prioritized for different...
High resolution natural color imagery collected by uncrewed aircraft system (UAS) for mapping channel and vegetation change along a 6-mile reach of the Middle Green River at Ouray National Wildlife Refuge near Ouray, Utah from 2020-2023
The U.S. Geological Survey collected low-altitude airborne natural color imagery via a fixed-wing uncrewed aircraft system (UAS) for mapping channel and vegetation change along a 6-mile reach of the Middle Green River at Ouray National Wildlife Refuge near Ouray, UT. Visual imagery was collected in jpg format and Structure-from-Motion (SfM) photogrammetry techniques were applied (Over et...
High resolution natural color imagery collected by uncrewed aircraft system (UAS) for mapping channel and vegetation change along a 7-mile reach of the Middle Green River at Horseshoe Bend near Jensen, Utah from 2020-2023
The U.S. Geological Survey collected low-altitude airborne natural color imagery via a fixed-wing uncrewed aircraft system (UAS) for mapping channel and vegetation change along a 7-mile reach of the Middle Green River at Horseshoe Bend near Jensen, UT. Visual imagery was collected in jpg format and Structure-from-Motion (SfM) photogrammetry techniques were applied (Over et al., 2021)...
Experiences of experts in managing and researching chronic wasting disease obtained through 2023 semi-structured interviews
The provided dataset is the coded analysis of qualitative semi-structured interviews conducted with managers and researchers who are experts on chronic wasting disease (CWD). CWD is a transmissible spongiform encephalopathy disease that affects species in the Cervidae family. CWD has also proven difficult to manage and the disease continues to spread across North America and parts of...
