Cheatgrass [PDF]

, 2013
The invasion of non-native species, mainly cheatgrass (Bromus tectorum), into our rangelands, especially following the destruction caused by wildfires, has made it necessary to find viable options for the restoration of native plant species to these ...

Cheatgrass distribution modeling using soil microclimate

, 2023
Here we provide the data and code used within our analysis. We used these data and code to understand the abiotic factors that drive cheatgrass distribution and apply that understanding across space and time to understand climate change effects on ...

Fire regime shift reveals 17th century socio‐ecological change in the Rio Grande del Norte National Monument, New Mexico

Ecosphere, Volume 17, Issue 9, September 2026.
Abstract Humans have influenced ecosystems for millennia, and social changes can have notable ecological effects. Recent human influence on ecosystems is exemplified by the collapse of fire regimes circa 1900 in the western United States due to increased grazing, fire suppression, and declining Indigenous fire use.

Climate-Driven Shifts in Soil Temperature and Moisture Regimes Suggest Opportunities to Enhance Assessments of Dryland Resilience and Resistance

Frontiers in Ecology and Evolution, 2019
Assessing landscape patterns in climate vulnerability, as well as resilience and resistance to drought, disturbance, and invasive species, requires appropriate metrics of relevant environmental conditions.

Effects of wildfire on the distribution of mammals and birds in a working shrub‐steppe landscape

Ecosphere, Volume 17, Issue 9, September 2026.
Abstract The intensity, frequency, and extent of wildfire have increased drastically in the sagebrush (Artemisia spp.) ecoregion within Washington, USA, over the last few decades. Wildfire on this landscape, already modified and fragmented by agriculture and other disturbances, may challenge the persistence of wildlife that depend on continuous ...

Differentiating Cheatgrass and Medusahead Phenological Characteristics in Western United States Rangelands

Remote Sensing
Expansions in the extent and infestation levels of exotic annual grass (EAG) within the rangelands of the western United States are well documented. Land managers are tasked with developing plans to limit EAG spread and prevent irreversible ecosystem ...

Grazing intensity effects on herbaceous community composition in burned sagebrush steppe

Ecosphere, 2023
There is limited knowledge of grazing impacts on longer term plant community dynamics following fire in sagebrush steppe. This study evaluated vegetation response to different intensities of deferred rotation cattle grazing over 16 years (2007–2022) on ...

De novo genome assembly of the fungal plant pathogen Pyrenophora semeniperda. [PDF]

PLoS ONE, 2014
Pyrenophora semeniperda (anamorph Drechslera campulata) is a necrotrophic fungal seed pathogen that has a wide host range within the Poaceae. One of its hosts is cheatgrass (Bromus tectorum), a species exotic to the United States that has invaded natural

Microsite selection improves post‐fire restoration of singleleaf pinyon pine on Washoe Tribal lands in the Pine Nut Mountains, NV, USA

Restoration Ecology, Volume 34, Issue 7, September 2026.
Abstract Introduction Singleleaf pinyon pine (Pinus monophylla) holds both ecological and cultural significance for Indigenous Tribes of the Great Basin, such as the Washoe Tribe of Nevada and California. Recent wildfires on Washoe Tribal lands have resulted in the loss of important pinyon pine groves, prompting collaborative efforts to develop post ...

Invasion of perennial sagebrush steppe by shallow-rooted exotic cheatgrass reduces stable forms of soil carbon in a warmer but not cooler ecoregion

Environmental Research Communications
Soil organic carbon (‘SOC’) in drylands comprises nearly a third of the global SOC pool and has relatively rapid turnover and thus is a key driver of variability in the global carbon cycle.
