Herbicide protection seed coating technology for improving restoration success in Great Basin sagebrush plant communities Open
Introduction Invasive annual grasses (IAGs) pose a significant threat to sagebrush rangelands, but restoring native perennial species using seed is challenging because pre‐emergent herbicides, used to control IAGs, also harm desired seedli…

Deeper Seeding Allows Bunchgrass Establishment While the Pre-emergent Herbicide Indaziflam Controls Invasive Annual Grasses Open
Restoration of annual grass-invaded rangelands is often a management priority. Pre-emergent herbicides are an effective restoration tool to reduce annual grasses but can negatively impact seeded vegetation. Hence, seeding is often delayed …

Post-fire management decisions have consequences: Drill-seeding disturbance and effects of co-seeding introduced with native bunchgrasses Open
Wildfires and the demand for post-fire seeding are increasing in the sagebrush ecosystem threatened by invasive annual grasses. Drill-seeding bunchgrasses after wildfire is a common strategy for limiting annual grasses. However, there are …

Evaluation of blood markers of stress in beef cows during exposure to virtual fence stimuli Open
Containing cattle with a virtual fence (VF) has gained considerable attention. VF technology uses auditory and electric stimuli to contain or exclude cattle from predetermined areas, which has raised concerns over cattle welfare. We evalua…

Ecological benefits of strategically applied livestock grazing in sagebrush communities Open
There are concerns about the negative consequences of non‐native livestock grazing of sagebrush communities, especially since these communities are experiencing unpreceded threats from invasive annual grasses, altered fire regimes, and cli…

Sagebrush Ecosystems are More Than Artemisia: The Complex Issue of Degraded Understories in the Great Basin Open
Plant communities in a stable, long-term state with high sagebrush cover and low desirable perennial herbaceous cover and/or relatively high invasive annual cover are widespread across the Great Basin and distinct from areas affected by wi…

Long-Term Effects of Revegetation Efforts in Annual Grass−Invaded Rangeland Open
Invasive annual grasses, such as medusahead (Taeniatherum caput-medusae [L.] Nevski), have invaded tens of millions of hectares of the sagebrush ecosystem. These invasions severely reduce ecosystem goods and services provided, as well as i…

Wyoming Big Sagebrush Transplant Survival and Growth Affected by Age, Season of Planting, and Competition Open
Wyoming big sagebrush (Artemisia tridentata Nutt. ssp. wyomingensis [Beetle & A. Young] S. L. Welsh) has decreased from its historic prevalence across the sagebrush steppe in part because of its interaction with invasive annual grasses and…

Fire needs annual grasses more than annual grasses need fire Open
Sagebrush ecosystems of western North America are experiencing widespread loss and degradation by invasive annual grasses. Positive feedbacks between fire and annual grasses are often invoked to explain the rapid pace of these changes, yet…

A recruitment niche framework for improving seed‐based restoration Open
As larger tracts of land experience degradation, seed‐based restoration (SBR) will be a primary tool to reestablish vegetation and ecosystem function. SBR has advanced in terms of technical and technological approaches, yet plant recruitme…

Is Crested Wheatgrass Invasive in Sagebrush Steppe with Intact Understories in the Great Basin? Open
Seeding crested wheatgrass (Agropyron desertorum [Fisch.] Schult.) in the sagebrush steppe is a controversial management action. There are concerns that crested wheatgrass may invade new areas and exclude native vegetation because many for…

Assessment of multiple herbicide protection seed treatments for seed-based restoration of native perennial bunchgrasses and sagebrush across multiple sites and years Open
The invasion of exotic, annual plant species is a leading contributor to ecological degradation in drylands globally, and the use of pre-emergent herbicide to control these species is common. Pre-emergent herbicides pose challenges for see…

Manipulation of Rangeland Wildlife Habitats Open
Rangeland manipulations have occurred for centuries. Those manipulations may have positive or negative effects on multiple wildlife species and their habitats. Some of these manipulations may result in landscape changes that fragment wildl…

Where There's Smoke, There's Fuel: Dynamic Vegetation Data Improve Predictions of Wildfire Hazard in the Great Basin Open
Wildfires are a growing management concern in western US rangelands, where invasive annual grasses have altered fire regimes and contributed to an increased incidence of catastrophic large wildfires. Fire activity in arid, nonforested ecos…
