Functional group cover and treatment data for 13 sites in the Great Basin with reburn history
Land management treatments in sagebrush steppe are an important opportunity to break the annual-grass fire cycle, provided they offer long-lasting resistance to annual-grass invasion and do not burn. However, for BLM areas seeded as part of the Emergency Stabilization and Rehabilitation (ESR) program, one of the largest programs for land management treatments, about 1/4 have at least...
Plant cover data collected on roadsides treated with herbicide and bioherbicide in SW Idaho
The exotic grass-fire cycle is degrading semiarid rangelands, such as the vast areas of shrub-steppe in North America now invaded by fire-promoting cheatgrass. Chemical- or bio-herbicides are sprayed onto soils to inhibit the invaders, but information on chemical- or bio-herbicide effects on plant communities is limited. We asked how the plant community responded to the bioherbicide...
Plant cover, density, and growth measurements from burned and unburned plots treated with indaziflam four years after the Soda fire
Protection of intact habitat from the spread of invasive plants is a global priority, especially where the invaders alter wildfire occurrence. Invasion of perennial sagebrush-steppe ecosystems by cheatgrass and other fire-promoting exotic annual grasses (EAGs) is one of the most notorious examples of this problem. Protection and expansion of the remaining intact "core" habitat sagebrush...
Simulated juvenile Chinook salmon movement and growth in the Yankee Fork of the Salmon River, Idaho: Model input parameters and results
The growth potential and movement propensity of juvenile Chinook salmon (Oncorhynchus tshawytscha) was simulated across 16 representative reaches in the Yankee Fork of the Salmon River (YFSR), Idaho. For growth potential, we used the Aquatic Trophic Productivity model, which incorporates dynamics of the food web members and the stream-riparian conditions at each reach. Environmental...
FLOwPER Database: StreamFLOw PERmanence field observations, Jan 2023 - Dec 2023
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 mobile data collection application. Additional information to describe the field conditions are included as part of the survey. Field observations in the...

Global gridded dataset of terrestrial biological nitrogen fixation across natural and agricultural biomes
This dataset includes global rasters of terrestrial biological nitrogen fixation (BNF) rates (in kg N/ha/y) for each major N-fixing niche in natural biomes (trees, shrubs, herbs, soil, litter, dead wood, ground mosses, biocrusts, and epiphytic lichens) and agricultural biomes (legume crops, forage legumes, and rice). It also includes total natural terrestrial, total agricultural, and...
A global dataset of terrestrial biological nitrogen fixation
This dataset includes field measurements of biological nitrogen fixation (BNF) in all major N-fixing niches across natural terrestrial biomes globally. The dataset comprises 32 variables including site location, biome type, N-fixing niche, sampling year, quantification method, BNF rate (in kg N/ha/y), the percentage of nitrogen derived from the atmosphere, N-fixer or N-fixing substrate...
California condor and black vulture Highly Pathogenic Avian Influenza vaccine trial
In 2023, critically endangered California condors experienced an outbreak of highly pathogenic avian influenza (HPAI). We evaluated safety, immunogenicity, vaccination strategies, and correlates of antibody response of a conditionally licensed influenza vaccine for poultry in black vultures and then California condors. These data represent the correlates of antibody response, including...
Comparison of environmental DNA sampling protocols for detection of stream fishes in the Pacific Northwest, 2019
This dataset contains environmental DNA (eDNA) data (field, extraction, and qPCR) for rainbow trout sampling efforts conducted in the Pacific Northwest in 2019. Samples were collected using three eDNA sampling methods. Also included are qPCR data for extraction negatives, no-template controls (NTC), and standard dilutions of rainbow trout gBlock. NTC and gBlock qPCR data were used to...
Population viability assessment of native fish species in the Pacific Northwest accounting for instream conditions of water temperature and streamflow permanence
This data release contains geospatial representations of population viability analysis (PVA) of 23 species of Pacific Northwest non-salmonid fishes. The analysis evaluated long term species persistence (~100 years) based on species distribution models that combined 1) modeled climate, 2) instream conditions, and 3) presence/absence fish data based on species needs and current climate...
Species distribution models and model performance evaluations of twenty-four fishes native to Pacific Northwest US
This data release provides spatial data for species distribution models developed for 24 stream fishes native to the Pacific Northwest, USA and associated model evaluation metrics used to determine the best supported model. These models support a larger analysis for understanding native stream fish vulnerability in the region, specifically population viability analyses built to determine...
