Cheatgrass--A Challenge to Range Research

Journal of Forestry, 1947
Abstract 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.

Fuel Properties of Effective Greenstrips in Simulated Cheatgrass Fires

Environmental Management, 2022
Invasive 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.

Evapotranspiration from a Greasewood‐Cheatgrass community

Water Resources Research, 1972
Groundwater 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, 1978
AbstractThe 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.
