Decadal effects of fuel treatments and annual grass invasion on sagebrush ecosystem carbon stocks
EcosphereFuel treatments are implemented across large spatial scales in sagebrush (Artemisia spp.) ecosystems of the US Intermountain West to limit wildfire risk and spread, but treatment effects on ecosystem carbon storage remain poorly understood.

Integrated Management of Cheatgrass (Bromus tectorum) with Sheep Grazing and Herbicide [PDF]
Agronomy, 2019 Cheatgrass (Bromus tectorum L.) is one of the most problematic weeds in western United States rangelands and sagebrush steppe. It responds positively to different forms of disturbance, and its management has proven difficult.

Pre‐fire grazing and herbicide treatments can affect post‐fire vegetation in a Great Basin rangeland
Ecological Solutions and Evidence, 2023 Management of wildfire associated with spread of the highly invasive annual grass Bromus tectorum (cheatgrass) is a critical need in the western U.S. We investigated the utility of coupling common rangeland management strategies pre‐fire to modify post ...

Negative effects of an exotic grass invasion on small-mammal communities. [PDF]
PLoS ONE, 2014 Exotic invasive species can directly and indirectly influence natural ecological communities. Cheatgrass (Bromus tectorum) is non-native to the western United States and has invaded large areas of the Great Basin. Changes to the structure and composition

Rapid Surveys Reveal Temporal Variation in Flowering Community Phenology in a Great Basin Desert Ecosystem. [PDF]
Ecol EvolAcross four years of surveys in an arid Great Basin ecosystem, community flowering phenology showed strong seasonal, interannual, and trait‐based variation, with most differences occurring in spring and little variation in fall. Flowering patterns broadly corresponded with interannual climate variability, consistent with the importance of moisture ...

Cheatgrass and Grazing Rangelands [PDF]
Rangelands, 2007 Abstract The presence of annual grasses creates a controversy between livestock men and grazing administrators involving the following question: Do annual grasses indicate overgrazing? Would the annual grasses be largely absent from Nevada ranges if there had been no grazing?

Invasive <i>Lupinus polyphyllus</i> Alters Functional Traits and Life Strategies of Native Species. [PDF]
Ecol EvolIn grasslands invaded by Lupinus polyphyllus, native plant species exhibit shifts in functional traits toward increased height, larger leaf area, higher specific leaf area, and lower leaf dry matter content compared to noninvaded sites. These changes indicate a reduced investment in stress tolerance and a greater allocation to competitive or ruderal ...
