Suppression of Cheatgrass by Perennial Bunchgrasses
Rangeland Ecology & Management, 2020Abstract Long-term control of the invasive annual grass cheatgrass is predicated on its biological suppression. Perennial grasses vary in their suppressive ability. We compared the ability of a non-native grass (“Hycrest” crested wheatgrass) and two native grasses (Snake River wheatgrass and bluebunch wheatgrass) to suppress cheatgrass.

Fuel Properties of Effective Greenstrips in Simulated Cheatgrass Fires
Environmental Management, 2022Invasive annual grasses alter fire regime in steppe ecosystems, and subsequent trends toward larger, more frequent wildfires impacts iconic biodiversity. A common solution is to disrupt novel fuel beds comprising continuous swaths of invasive annual grasses with greenstrips-linear, human-maintained stands of less-flammable vegetation.

Cheatgrass--A Challenge to Range Research
Journal of Forestry, 1947Abstract To determine the ecologic and economic importance of cheatgrass is a challenge to the men in range research. This poorly understood species produces a large volume of herbage over extensive acreages and is undoubtedly the most important forage plant on southern Idaho ranges.

Evapotranspiration from a Greasewood‐Cheatgrass community
Water Resources Research, 1972Groundwater elevation, soil moisture, and precipitation were monitored to evaluate the components of water loss from two greasewood‐cheatgrass (Sarcobatus vermiculatus‐Bromus tectorum) communities in south central Washington. Annual evapotranspiration was 21–25 cm, 18–31% of which was the transpiration of groundwater.

Accumulation of 99Tc by Tumbleweed and Cheatgrass Grown on Arid Soils
Health Physics, 1978AbstractThe accumulation of Tc by tumbleweed and cheatgrass was measured for five soils at one, two, and three months' harvest times. The initial soil concentration of 1.0 pg 99Tc/g added to the soil as pertechnetate, was traced by 95mTc.

Cheatgrass distribution modeling using soil microclimate
2023Here 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 cheatgrass.

Microsatellite markers for Bromus tectorum (cheatgrass)
Molecular Ecology Notes, 2002Abstract Bromus tectorum (cheatgrass) is a flourishing invasive weed in the western United States. The objective of our study is to characterize its genetic diversity. We made a B. tectorum genomic library in lambda phage and screened approximately 4000 clones for poly CA and poly CT dinucleotide repeats.

Energy and Carbon Balances in Cheatgrass: An Essay in Autecology
Ecological Monographs, 1975Biotic and abiotic pathways of incident energy are rarely considered together in comparable detail, so little is known about whether energy or carbon relations remain constant in contrasting energy environments. An experiment to determine the fates of energy and carbon in cheatgrass (Bromus tectorum L.) was carried out on steep (40°) north— and south ...
