Argopyron spictatum
Bluebunch wheatgrass
What is it?
Bluebunch wheatgrass is, as the name implies, a bunchgrass. It grows to anywhere from one foot to nearly three feet tall. It is a plant native to the western United States and is in fact the state grass for both the states of Montana and Washington. Argopyron spictatum is found from foothills to upper montane areas ranging from 4,000 to 9,000 feet in elevation. It grows well in deep, well-drained soils and is often dominant on dry open slopes, composing up to 60% of the native cover in some area.
Why is it important?
Bluebunch wheatgrass is good forage for deer, wild sheep, and other large game. The tall leaves can provide cover for young antelope, ground fowl, and other small animals. The seeds are a food source for birds and small rodents. Its roots stabilize soil and prevent erosion by wind and water. Because Argopyron spictatum is not resistant to overgrazing, it can be an indicator of healthy rangeland.
