Bearded Creeper

Origin: Eurasia

Current Distribution: Not present in BC at this time. Present in Washington State

Habitat Preferences: Pastures, grasslands, rangelands, hayfields, forests, riparian areas, roadsides, railroads and waste places.

Agricultural: Common crupina infests hay and other forage crops. It also reduces pasture capacity and livestock productivity. Decreases forage.
Ecological: Infests grasslands and open forests where it competes with native species

Legal Status: Weed Control ActSeeds ActCommunity Charters Act.

Prevention: Prevention includes using clean seed, hay, grain, and straw and watching for common crupina in crops and disturbed areas. Maintain good ground cover in pastures. 

Treatment: Infestations can be controlled with herbicides. Biocontrol agents are not available. Cutting or grazing can stimulate lateral growth producing larger quantities of seed and is not recommended.
