Cheatgrass Invasion in Salt Desert Shrublands: Benefits of Postfire Reclamation [PDF]
Rangeland Ecology & Management, 2007 Abstract In 1998, fires burned more than 11 330 ha of rangeland on Dugway Proving Ground in Utah's west desert. Postfire revegetation was implemented in 2 affected salt desert shrub communities (greasewood; Sarcobatus vermiculatus Hook. and black sagebrush/shadscale; Artemisia nova A. Nels; Atriplex confertifolia Torr.

Grass Hosts of Cereal Aphids (Hemiptera: Aphididae) Between Wheat-Cropping Cycles in South Dakota [PDF]
, 2018 Several grasses may serve as alternative hosts for cereal aphids during the interim between small-grain crops in South Dakota, but field studies to determine which grasses are important have not been undertaken.

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.

Protecting restoration investments from the cheatgrass‐fire cycle in sagebrush steppe
Conservation Science and Practice, 2021 The U.S. federal government has recently committed to the difficult task of slowing and managing the invasive grass‐fire cycle in sagebrush steppe, where property, livelihoods, and entire ecosystems are at risk.

Cheatgrass and Yellow Starthistle Growth at 3 Soil Depths [PDF]
Journal of Range Management, 1997 Community dynamics and dominance on cheatgrass (Bromus tectorum L.) and yellow starthistle (Centaurea solstitialis L.) infested rangeland appear to be influenced by resource acquisition rates and duration of growth. Objectives were to determine the effects of densities, proportions, and soil depth on the growth rate and duration of growth of these ...

Does Wildfire and Cheatgrass Invasion in a Sage-steppe Ecosystem Change Soil Texture? [PDF]
, 2014 Fire and land-use changes influence vegetation types and alter below-ground carbon storage and soil characteristics; additionally, shrub-steppe environments are prone to cheatgrass invasion and subsequent alterations in soil morphology and ...

Competitive Interaction between Crested Wheatgrasses and Cheatgrass [PDF]
, 1993 Current revegetation practices in the lntermountain West include the use of Nordan (Agropyron desertorum) and Hycrest (A. cristatum x desertorum) crested wheatgrass on rangeland susceptible to cheatgrass (Bromus tectorum) invasion, although little quantitative data exists that compares their competitive abilities.

Spatial Variation in Postfire Cheatgrass: Dinosaur National Monument, USA
Fire Ecology, 2012 A major environmental problem in semi-arid landscapes of western North America is the invasion of native vegetation by cheatgrass (Bromus tectorum L.), an annual Eurasian grass that covers >40 million ha of range and woodland in the western US. Cheatgrass can be especially problematic after fire—either prescribed fire or wildfire.
