Both descriptions could refer to areas recovering from wheat cultivation years earlier, and the grasses could be non-native annual species (e.g., Bromus
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.
Similar response also was observed on Bromus
tectorum with aminopyralid, another auxin herbicide (RINELLA et al., 2013).
The species fanning the flames of western wildfires is an invasive grass known as cheatgrass (Bromus
Ces therophytes sont essentiellement formees par Avena sterilis, Bromus
rubens, Brachypodium distachyum, Hordeum murinum, Chenopodium album, Adonis luteola, Lotus hispidus, Trifolium angustifolium, Malva sylvestris,Plantagoalbicans, Plantagoserraria, Galium aparine, Calendula arvensis, Anagallis arvensis, etc.
In 2014, the species cover in the control plot for both soil types averaged 36% medusahead, 16% yellow starthistle, 13% slender oat (Avena barbata Pott ex Link), 12% annual ryegrass, 6% ripgut brome (Bromus
diandrus Roth), 6% soft chess, 4% hare barley (Hordeum murinum L.
Sampled plants included the following forage types and genera: shrubs (Artemisia, Chrysothamnus, Eriogonum, Krascheninnikovia, Salix, Sarcobatus); forbs (Alyssum, Atriplex, Phlox); grasses (Agropyron, Bromus
, Oryzopsis, Poa); sedges-rushes (Carex); conifers (Juniperus); and lichens.
Floristic composition showed that Poa was leading genus with 04 species (11.11%) followed by Avena, Bromus
, Hordeum and Lolium with 02 (5.55%) species each while the remaining genera were represented by one species each (Fig.
Gramineae species such as Bromus
tomentellus Boiss., Festuca valesiaca Schleich ex.
A visitor at meanseeds.com brought ripgut brome (Bromus
diandrus) to my attention as a known problem in Northern California, especially, though the USDA map shows a range fairly similar to mouse barley: plants.usda.gov/core/profile?symbol=BRDIR.
