To contrast the performance of invasive plants and native plants, we selected five invasive species (i.e., Bidens pilosa, Bromus tectorum
, Centaurea stoebe, Eupatorium adenophorum, and Solidago canadensis), which are successful invaders, and six native species (i.e., Achillea millefolium, Bromus japonica, Eupatorium chinense, Helianthus annuus, Poapratensis, and Vulpia octoflora), which are dominant/common natives in the invaded regions.
Effects of growth regulator herbicide on downy brome (Bromus tectorum
) seed production.
The species fanning the flames of western wildfires is an invasive grass known as cheatgrass (Bromus tectorum
Suppression of annual Bromus tectorum
by perennial Agropyron cristatum Roles of soil nitrogen availability and biological soil space.
Several invasive species are also locally abundant, including Russian thistle (Kali tragus), goat head (Tribulus terrestris), and cheatgrass (Bromus tectorum
Cultivated as green manure, residues of yellow sweetclover effectively suppress weeds during fallow season and control the perennial weeds dandelion (Taraxacum officinale) and perennial sowthistle (Sonchus arvensis L.), as well as the annuals kochia (Kochia scoparia L.), flixweed (Descurainia sophia L.), Russian thistle (Salsola iberica), and downy brome (Bromus tectorum
) (Blackshaw et al., 2001).
Its stereo hyperspectral machine vision system allows the iron goat to be species-selective, so it can target invasive species like Bromus tectorum
(a noxious weed that invades grassland communities and displaces native plants), which often thrive in disturbed areas.
(1996) suggested that Bromus tectorum
's populations arising from a favorable but unpredictable environment have a higher degree of dormancy than those located in an extreme but predictable environment.
Cool-season grasses in all locations included Kentucky bluegrass (Poa pratensis L.), tall fescue (Festuca arundinacea Schreb.), smooth bromegrass (Bromus inermis L.), and downy bromegrass (Bromus tectorum
L.; Junegrass, Cheatgrass, Downy Chess or Brome; Old-field along S.

population dynamics at high elevation," Oecologia, vol.
The annual grass weed downy brome, or cheatgrass (Bromus tectorum
L.), infests 22 million ha in the Western United States  and has degraded croplands used for small grain production and rangelands used for grazing.
