Life History/Ecology: Smooth brome is a cool season, perennial grass that can spread by seed and Smooth Brome: A tiny white flowering plant, the Yukon Draba is growing in the Alsek Valley. Smooth brome is a cool season exotic that is especially troublesome in disturbed portions of old pastures in the tallgrass and mixed prairie regions. The awnless lemmas, from which the species derives its Latin name, distinguish Bromus inermis from both the introduced and similar Bromus erectus and from the native Bromus inermis subsp. The ascending or stiff branches of the open panicle are a key characteristic distinguishing Bromus inermis and Bromus erectus from a group of similar native bromegrasses. It is a primary component of most hay productions. Invasive plants have variable effects on net nitrogen cycling, but how invasion alters gross N cycling is poorly understood. Smooth brome is a widespread, invasive grass throughout western Canada, where its introduction has resulted in significant losses of above-ground plant biodiversity, up to 70% in some cases (Otfinowski, Kenkel & Catling 2007; Wilson & Pinno 2013). A controlled burn in the spring will set back smooth brome and encourage the growth of native warm-season grasses. ssp. INVASIVE PLANTS OF OHIO Fact Sheet 13 Smooth Brome Bromus inermis DESCRIPTION: Smooth brome is a rhizomatous, cool-season perennial grass which can attain a height of 4 feet. Introduced as a forage plant from Eurasia over 130 years ago, its drought tolerance fast-tracked its popularity after the Dust Bowl era. Stems are glabrous and leaves can be 6 to 16 inches long. ssp. It is known to invade undisturbed sites. inermis – smooth brome Subordinate Taxa. We examine how Bromus inermis (smooth brome) invasion affects gross N cycling rates and investigate potential mechanisms for the changes including relationships between smooth brome and ammonia-oxidizing bacteria (AOB) and archaea (AOA), plant community … Found in 6 states at 10 Corps projects Click (number) to view projects per state. (0.6-1.9 cm) wide, 6-15 in. Brome is a cool-season grass, which means that it is actively growing at fairly cool temperatures in the spring. They’ll eat other invasive grasses too (I watched them working on Kentucky bluegrass this morning, in fact) but if smooth brome is available, they’ll hit that first. [Online] Accessed: [09-05-2013]. We investigated the effects of invasive smooth brome (Bromus inermis) on grassland soil bacterial community structure using massively parallel sequencing of the 16S rRNA gene to determine bacterial community richness, evenness, composition and beta diversity (UniFrac indices) of soils collected along a gradient of smooth brome abundance. inermis – smooth brome Variety: Bromus inermis Leyss. “It is drought resistant” (Cook 1943). Iowa; Illinois; Kansas; Nebraska; Ohio; ES Status. system allows it to tolerate prolonged drought conditions. Background: Smooth Brome. The effects of invasive species on the patch dynamics (establishment, growth, and local extinction) of native species are not well studied, owing to the need for relatively fine-scale data on the distribution of species. (Spring) Burn. Unfortunately Smooth Brome started to invade the area and concern was raised it may reduce the habitat for the Yukon Draba. Foliage The leaves have a fine texture and are alternate, 0.25-0.75 in. Minnesota Department of Natural Resources. Smooth bromegrass was widely used in the upper half of North America during the late 19th and early 20th centuries, with distinguishable northern and southern varieties. Yukon Invasive Species Council PO ox , Y infoyukoninvasives.com www.yukoninvasives.com Smooth Brome Bromus inermis Common Name: Smooth Brome Scientific Name: Bromus inermis Family: Poaceae Description Smooth brome is an important agricultural plant. Old stands may become sod-bound, producing many short, leafy stems but few or no seed heads. General Description: (15.2-38.1 cm) long, glabrous, flat, and grayish blue on the upper surface and green on the lower surface. A native grass of Europe and Asia, Brome was introduced into the U.S. in the 1880’s. Smooth brome seed sown in late fall to early winter in central Utah germinated and produced roots and shoots under deep snow cover” (Howard 1996). Smooth Brome Management Smooth Brome Management Smooth brome (Bromus inermis) is one of the most widespread challenges in habitat management. pumpellianus. Illinois Wildflowers. ... awnless brome, Hungarian bromegrass. For those who want to eradicate this plant, burn in the spring when the brome is 4 to 10 inches tall, while there is still enough dry fuel present to make burning possible.

Invasive Listing Sources. Smooth brome is a grass that was introduced into the U.S. from Europe in the late 1800s and was widely established due to its resistance to depression-era droughts.
