Predicted exotic annual grass abundance in rangelands of the western United States using various precipitation scenarios for 2022 Predicted exotic annual grass abundance in rangelands of the western United States using various precipitation scenarios for 2022
Invasion of exotic annual grass (EAG), such as cheatgrass (Bromus tectorum), red brome (Bromus rubens), and medusahead (Taeniatherum caput-medusae), could have irreversible degradation impact to arid and semiarid rangeland ecosystems in the western United States. The distribution and abundance of these EAG species are highly influenced by weather variables such as temperature and...
Drilling, construction, geophysical data, and lithologic log for borehole USGS 151 Drilling, construction, geophysical data, and lithologic log for borehole USGS 151
In 2020, the U.S. Geological Survey (USGS), in cooperation with the U.S. Department of Energy (DOE) for Naval Reactors Laboratory Field Office or Naval Reactors Facility (NRF), drilled and constructed borehole USGS 151 (433846112540701) for stratigraphic framework analyses at the Idaho National Laboratory (INL) near the NRF, located in southeastern Idaho. Borehole USGS 151 was...
Colorado River at Windy Gap near Granby, CO - 2021/07/27 Water Surface Velocity Map Using Particle Image Velocimetry Colorado River at Windy Gap near Granby, CO - 2021/07/27 Water Surface Velocity Map Using Particle Image Velocimetry
The dataset consists of a shapefile of measurements of surface velocity magnitude and direction at the Colorado River at Windy Gap near Granby, CO, on July 27, 2021. The dataset contains approximately 1 km of river length. The surface velocity measurements were made by applying Large-Scale Particle Image Velocimetry (LSPIV) techniques, using overlapping videos collected by small Unmanned...

raventools: A package to facilitate raven management in the western U.S. The raventools package centralizes several publicly available geospatial datasets that are essential to mapping and modeling for common raven (Corvus corax) management applications, including raven occurrence and density data, sensitive species distribution data, raven subsidy data, and Greater sage-grouse...
Code to analyze multi-state, multi-scale dynamic occupancy models for amphibians in Yosemite National Park Code to analyze multi-state, multi-scale dynamic occupancy models for amphibians in Yosemite National Park
The purpose of this study was to evaluate how extreme variation in precipitation in the Sierra Nevada of California, USA, in the early 21st Century affected adult occupancy and the probability of reproduction of amphibians. The study used a 15-year data set to relate site characteristics to initial probability of occurrence of adults, and additional site-specific and dynamic (e.g...
