[35][5]  A decline in the health of the BSC community serves as an early warning indicator for Bromus tectorum invasion. This lack of understanding is complicated by the episodic nature of establishment in arid grasslands. The use of seeding another non-native to control an exotic, problem species is called assisted succession. 2000. Bromus tectorum has demonstrated a quantitative and qualitative response to recent and near-term changes in the concentration of atmospheric carbon dioxide. Integrated Taxonomic Information System. Culms. Studies have suggested that herbicide usage may select for warm season grasses and decrease the abundance of cool season grasses. Google. Conservation Services Division. [9] B. tectorum may be mistaken for a bunchgrass because it may send up shoots that give it the appearance of having a rosette. [10] The flowers of B. tectorum are arranged on a drooping panicle with approximately 30 spikelets with awns and five to eight flowers each. University of Wyoming; Colorado State University. Bromus tectorum, known as downy brome, drooping brome[1] or cheatgrass, is a winter annual grass native to Europe, southwestern Asia, and northern Africa, but has become invasive in many other areas. Renewable Resource Center. Characteristics of a resistant native community, Learn how and when to remove these template messages, Learn how and when to remove this template message, "THE BIOLOGY OF CANADIAN WEEDS. The reduction of native plants and the increased fire frequency caused by B. tectorum prompted the United States Fish and Wildlife Service (USFWS) to examine if the greater sage-grouse needed to be listed as a threatened or endangered species due to habitat destruction. [12] A study showed that it had the capability to reduce soil moisture to the permanent wilting point (minimal soil moisture required for a plant not to wilt) to a depth of 70 centimetres (28 in), reducing competition from other species. Bromus tectorum var. Other common names in the USA include bronco grass, six weeks grass and military grass. Notes on Taxonomy and Nomenclature Top of page. American Journal of Botany 89(4):602-612.

University of Nevada - Reno. [10] They are also moved as a contaminant in hay, grain, straw, and machinery. Pennsylvania Department of Conservation and Natural Resources. Naturalized in N. America. Prescribed burning alone reduces Bromus tectorum biomass for approximately two years. [3] It has become a dominant species in the Intermountain West and parts of Canada, and displays especially invasive behavior in the sagebrush steppe ecosystems where it has been listed as noxious weed. [2] It typically reaches 40–90 centimetres (16–35 in) tall, though plants as small as 2.5 centimetres (0.98 in) may produce seed. SCIENTIFIC NAME Bromus tectorum L. [Anisantha tectorum (L.)
