Smooth Brome
Common Name: Smooth Brome
Scientific Name: Bromus inermis
Family: Poaceae
Description
Smooth brome is an important agricultural plant. It is a persistent, nutritious hardy species that spreads through creeping rhizomes and by seed. It is known to invade undisturbed sites. Its hardiness and ability to suppress all other species by forming a thick mat of rhizomes has made it desirable for highway reconstruction projects in the past. Though not considered noxious, this species limits the habitat for native species.
Range in Yukon
Reported from every community except Old Crow; it is found along most Yukon highways and around old settlements far from roads or rivers.
Similar Species
Pumpelly’s brome (Bromus pumpellianus) is the native cousin of smooth brome, sometimes considered a subspecies. It has hairy flowers or seed casings (lemmas), unlike the hairless casings that give smooth brome its name. It is widespread throughout Yukon.
Ecological Impact
Smooth brome forms a dense sod that smothers and excludes native species decreasing natural biodiversity. Smooth brome inhibits natural succession.
Control
Once planted is difficult to remove. Mechanical treatment or herbicides may be required.
