Invasion of exotic annual grasses (EAG) and increased wildfire have led to an emphasis on managing rangeland plant communities for resistance to invasion and resilience to disturbances. In sagebrush steppe and similar rangelands, perennial bunchgrasses and particularly their roots are hypothesized to be primary contributors to the resistance and resilience. We asked how bunchgrass root...

Eighty-one monitoring plots within the Minidoka National Wildlife refuge on the Snake River Plain in south-central Idaho were surveyed in July-August from 2020 to 2023 to evaluate the effects of herbicides on the vegetation-community across areas that varied in both burn history and background cheatgrass abundance. Surveys consisted of line-point intercept measurements along two 6m or...

The 2022 Department of the Interior, Environment, and Related Agencies Appropriations Bill - the appropriations bill that funds the USGS - established a regional Integrated Water Availability Assessment study program in the Great Basin of the American West. Twenty saline lakes across California, Nevada, Oregon, and Utah were identified by USGS partners as priority ecosystems. They...

Comma-separated values (.csv) file containing data related to mercury in biota collected from Clear Lake, California. This data release supersedes Pierce, J.R., Feyrer, F., Young, M., Enos, E., Clause, J., Alpers, C., and Eagles-Smith, C.A., 2022, Mercury in fishes from Clear Lake, California, 2019 and 2020 (ver. 2.0, February 2022): U.S. Geological Survey data release, https://doi.org...

Bio-logging is central to study of wildlife, but questions remain about minimization of effects from bio-logging devices. Rarely considered are changes bio-logging devices induce on an animal’s center of mass (COM) and resulting losses of flight control and stability. In a related paper (Katzner and Young 2024), we applied established aeronautical principles to estimate how the COM of a...

Comma-separated values (.csv) files containing data related to mercury in soil, water, sediment, in-stream leaf litter, periphyton, and aquatic invertebrates collected in 2021-2022 from headwater streams associated with wildfires in the northwestern U.S.

Comma-separated values (.csv) file containing data related to mercury concentrations in dragonfly samples from the Willamette River Basin collected in 2023.

This geospatial layer is a spatial index for the Conservation Efforts Database (CED, https://conservationefforts.org/), serving as a spatial framework for summary reports by area (a.k.a. polygon). In addition, this SRU (Sagebrush Reporting Unit) data is an option for data providers to provide spatial ambiguity to alleviate concerns of too much spatial detail representing private...

This data set describes blood and tissue samples collected from Mariana common moorhens from 2000-2001 in Guam and Saipan.

IMPORTANT NOTE: This dataset includes spatial locations where streamflow permanence observations (continuous flow, discontinuous flow, and dry) were recorded using the FLOwPER (FLOw PERmanence) field survey available in the Survey 123. Additional information to describe the field conditions are included as part of the survey. Field observations in the FLOwPER Database have not been...

The dataset includes daily counts of the number of independent photo detections from camera traps for 15 mammal species. The camera traps were placed in three study reaches of the Elwha River, Washington between July 2021 and July 2023. The dataset also includes information about the camera station locations, and the calendar date and season when the photos were captured.

Data includes functional group cover of annual grasses, perennial grasses and shrubs, and model predicted fire behavior for the years of 2018-2021.
