Conservation Science and Practice, 2022 Interannual variation, especially weather, is an often‐cited reason for restoration “failures”; yet its importance is difficult to experimentally isolate across broad spatiotemporal extents, due to correlations between weather and site characteristics ...

Aboveground Total and Green Biomass of Dryland Shrub Derived from Terrestrial Laser Scanning [PDF]
, 2014 Sagebrush (Artemisia tridentata), a dominant shrub species in the sagebrush-steppe ecosystem of the western US, is declining from its historical distribution due to feedbacks between climate and land use change, fire, and invasive species.

Assessing the Success of Postfire Reseeding in Semiarid Rangelands Using Terra MODIS [PDF]
, 2012 Successful postfire reseeding efforts can aid rangeland ecosystem recovery by rapidly establishing a desired plant community and thereby reducing the likelihood of infestation by invasive plants.

Persistence of Idaho Fescue on Degraded Sagebrush-Steppe [PDF]
Journal of Range Management, 1999 Idaho fescue (Festuca idahoensis Elmer), a palatable native perennial bunchgrass, has persisted on degraded sagebrush-steppe despite invasion by alien plants, excessive livestock grazing, and increased density of woody vegetation due to fire suppression. Survival of these populations in the presence of competitive alien plants suggested 2 possibilities:

Revegetation of Medusahead-Invaded Sagebrush Steppe [PDF]
Rangeland Ecology & Management, 2010 Abstract Medusahead (Taeniatherum caput-medusae [L.] Nevski) is an exotic annual grass invading western rangelands. Invasion by medusahead is problematic because it decreases livestock forage production, degrades wildlife habitat, reduces biodiversity, and increases fire frequency.

The Effect of Seeding Treatments and Climate on Fire Regimes in Wyoming Sagebrush Steppe
Fire, 2021 Wildfire size and frequency have increased in the western United States since the 1950s, but it is unclear how seeding treatments have altered fire regimes in arid steppe systems.

Direct and Indirect Effects of Floral Defoliation on Photochemical and Non-Photochemical Chlorophyll Fluorescence Dynamics of a Semiarid Bunchgrass. [PDF]
Plant Environ InteractAfter herbivory, crested wheatgrass florets must scrub excess absorbed light as heat via regulated physiological processes or less effective unregulated means. We found clipped florets heightened physiological control while undamaged florets reduced unregulated dissipation of excess light energy.

Relative abundance of and composition within fungal orders differ between cheatgrass (Bromus tectorum) and sagebrush (Artemisia tridentata)-associated soils. [PDF]
PLoS ONE, 2015 Nonnative Bromus tectorum (cheatgrass) is decimating sagebrush steppe, one of the largest ecosystems in the Western United States, and is causing regional-scale shifts in the predominant plant-fungal interactions.
