Crested Wheat Grass
Common name: Crested Wheat Grass
Scientific name: Agropyron pectiniforme
Family: Poaceae
Description
Crested Wheat Grass is long lived (15 to 20 years), drought and fire tolerant and has an extensive root system. It spreads primarily via seed but may also spread via rhizomes. The spikes are flattened. It is used in agriculture and for revegetation but may become invasive in native situations.
Range in Yukon
Widespread agronomic species commonly used in seeding projects. Found throughout Yukon.
Similar Species
Crested wheat grass resembles the native wild rye (Elymus spp.) but their seeds are arranged like a comb (pectinate) along the stem.
Ecological Impact
It may form monotypic stands and inhibit growth of native species.
Control
Crested Wheat Grass is highly competitive and therefore needs to be controlled on the spot to prevent negative impact on native species. Control is a long-term process. Being perennial, clumps of plants must be removed, often leaving small bits of the root system that will regrow. Put plants into clear garbage bags and then leave them in the sun to kill off the plants and roast the seeds.
