Technical Abstract: Annual crested wheatgrass (Eremopyrum triticeum (formerly Agropyron triticeum])was introduced to North America from Central Asia. It is in the same Tribe of grasses, but not closely related to crested wheatgrass (Agropyron desertorum).The seed head looks like a miniature, compacted crested wheatgrass head with the spikelets imbricated and arranged at right angle to the rachis. The awns are short, but very sharp. During the last 5 years, the number and extent of infestations in the Great Basin has greatly increased. It appears to be replacing cheatgrass (Bromus tectorum) on drier, lower elevation sites. Annual crested wheatgrass produces little forage when green and is not grazed after seed ripe. Annual crested wheatgrass is another step in the seral communities of exotic invasive weeds that now characterize so much of Intermountain rangelands.
