Decision model simulation of the reintroduction of bull trout in the upper Lake Chelan basin, Washington Decision model simulation of the reintroduction of bull trout in the upper Lake Chelan basin, Washington
The feasibility of a potential bull trout (Salvelinus confluentus) reintroduction was simulated across 12 streams and river segments in the upper Lake Chelan basin using a population matrix model. The model considered habitat availability, life history expression, and assumptions regarding constraints on potential bull trout populations. Details of the simulation framework are described...
Biological soil crust metagenomic data from Horse Heaven Hills, Washington, measured in 2020 Biological soil crust metagenomic data from Horse Heaven Hills, Washington, measured in 2020
This dataset contains Sanger ITS sequences from biocrust lichen taxa collected at Horse Heaven Hills in Washington, USA. It also includes metagenomic biocrust lichen data from 20 plots at Horse Heaven Hills in Washington, USA. These data were collected by Bruce McCune and Heather Root in 2019-2020 and sequenced for ITS using bulk sequencing in the PacBio system at Brigham Young...

Comma-separated values (.csv) file containing data related to bat sampling from southwestern U.S. National Parks in 2023. Data file contains mercury concentrations in bat tissues and blood.
Field-informed plant functional and species cover related to fuels treatment boundaries observed in 2021 in southwestern Idaho Field-informed plant functional and species cover related to fuels treatment boundaries observed in 2021 in southwestern Idaho
Data includes species cover of cheatgrass (BRTE) and Russian thistle (SATR), as well as functional group cover of Sandberg's bluegrass (POSE), bare ground, litter, and shrubs for the year of 2021.
Drought-related responses of stream flow, climate, and vegetation productivity from the Donner und Blitzen watershed, Great Basin Desert, USA (1988-2020) 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 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.

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 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 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...
Vegetation and soil cover data in response to indaziflam and imazapic herbicide applications within Minidoka National Wildlife Refuge, Idaho, USA 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...
