Weed Specifications
| Type | Information |
|---|---|
| Toxicity | Non-toxic, but not palatable due to high silica content and stiff glumes and awns. |
| Best Management Practices |
Proper grazing management, minimize disturbance, thatch removal, good sanitation practices to avoid seed dispersal. |
| Habitat | Disturbed areas, degraded land, rangeland, thrives on high clay content soils, areas with cool wet winters and hot dry summers. |
| Root | Fibrous |
| Leaves | Bright green and upright. |
| Lifespan | Winter annual, germinates and emerges in fall and begins growing again in the spring, initiating growth early in the growth season and reducing moisture and nutrients for native perennial grasses. |
| Similar Looking Plants | Bottlebrush squirreltail, foxtail barley. |
| Important Information | Serious threat to rangeland, particularly in high clay content soils; stiff glumes and awns pose a risk to fleece and flesh; litter impedes growth and germination of other species, ties up nutrients, and increases fire danger. |
