Drought-related responses of stream flow, climate, and vegetation productivity from the Donner und Blitzen watershed, Great Basin Desert, USA (1988-2020)
Indicators of climatic, hydrologic, and ecological drought responses in water-related terrestrial and aquatic conditions within a single catchment in the northwestern Great Basin Desert and its associated stream network were developed from stream flow, climate and remote sensing sources for the time period of 1988 to 2020.
Importance of seed source selection when planting big sagebrush seedlings in a post-fire context: Assessment of subspecies, climate adaptation, and eco-physiological traits on early establishment
This dataset contains information on seedling survival, physiochemical, morphological, and eco-physiological characteristics of seedlings grown and planted from seed collected from different sagebrush populations as well as the climatic conditions of those seed source sites in relation to the common garden location in which they were planted.
Western North America terrestrial reptile climate-niche rasters and summary data (In press)
This data release supports the referenced publication 'Climate futures for lizards and snakes in western North America may result in new species management issues' in this metadata record. Data included in this release includes raster data outputs and resulting summaries from the analyses, described in the processing steps of this metadata record. In summary this release includes information for 1
Cover, basal diameter, height, and density of deep-rooted perennial grasses, and cover of exotic annual grasses and Poa secunda over the first five years following post-fire drill-seeding on the Soda Wildfire
Data includes functional group cover of exotic annual grasses, shallow rooted perennial grasses, and cover, basal diameter, height, and density of deep-rooted perennial grasses within the first five years after the 2015 Soda wildfire across post-fire drill-seeding treatments.
Abundance, cover, and root measurements of perennial bunchgrasses in the Owyhee Mountains, USA
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 abundance r
Vegetation and soil cover data in response to indaziflam and imazapic herbicide applications within Minidoka National Wildlife Refuge, Idaho, USA
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 50m transect
Saline Lake Ecosystems IWAA Lakes
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 include: Califor

Expanded dataset of measurements to be used in evaluating consequences for flight control and stability induced by attachment of bio-logging devices to birds and bats
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 flying bir
Mercury in soil, water, sediment, and biota in headwater streams associated with wildfires in the northwestern U.S., 2021-2022
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.
Mercury concentrations in dragonfly larvae from the Willamette River Basin, 2023
Comma-separated values (.csv) file containing data related to mercury concentrations in dragonfly samples from the Willamette River Basin collected in 2023.
Conservation Efforts Database Spatial Reporting Units (SRUs)
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 landowners’ effort
