Bromus tectorum

What to Eat

Edible parts: Seeds, Cereal

Edible Parts: Seed Edible Uses: Coffee Seed - cooked. A famine food, the small seed can be cooked into a gruel in times of food shortage. A coffee is made from the roasted seed.

How to Identify

An annual grass. It is erect and grows 60 cm high. The leaves are near the base and form a sheath. They are narrow and sword shaped. The leaf blades are 18 cm long. The flower panicle is 18 cm long and can be loose or dense. The spikelets are narrowly wedge shaped and fragile.

How to Grow

Plants are grown by seed.

Propagation: Seed - sow spring or autumn in situ and only just cover. Germination should take place within 2 weeks.

Medicinal Uses

Miscellany A paste made from the seeds is applied as a poultice to the chest to relieve chest pains.

Other Uses

Bedding Miscellany The leaves have been used as a bedding. B. tectorum is the most abundant forage species on many intermountain area rangelands of the USA [1d]. Special Uses

Bromus tectorum, known as downy brome, drooping brome, or cheatgrass, is a winter annual grass native to Europe, southwestern Asia, and northern Africa, but has become invasive in many other areas. It now is present in most of Europe, southern Russia, Japan, South Africa, Australia, New Zealand, Iceland, Greenland, North America, and western Central Asia. In the eastern US, B. tectorum is common along roadsides and as a crop weed, but usually does not dominate an ecosystem. 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. B. tectorum often enters the site in an area that has been disturbed, and then quickly expands into the surrounding area through its rapid growth and prolific seed production. 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. After the review was completed by the USFWS, Secretarial Order 3336 was signed with the goal of reducing the threat of rangeland fires and preserve habitat by reducing downy brome. Research has shown that ecosystems with a healthy biological soil crust and native plant community are resistant to B. tectorum invasion. In areas where B. tectorum is invasive, treatments that are being researched/used by land managers to control B. tectorum include seeding of native plants and non-native bunchgrasses to outcompete B. tectorum, herbicides, and prescribed burns. The effectiveness of these treatments is tightly linked to the timing of the water availability at the site. With precipitation shortly after herbicide and seeding treatments increasing the success, and overall high precipitation increases B. tectorum growth, causing the treatment effects to be statistically insignificant.

Other Information
