| 説明 | Cheatgrass has surrounded and engulfed crested wheatgrass in Metzger Farm Open Space in Westminster and Broomfield, Colorado. Cheatgrass has captured this area, but has not yet eliminated all other plants. This photo was taken across the hiking trail north of the covered picnic tables. The area by the picnic tables has become dominated by cheatgrass, with very few other plants. As shown in the next photo, the cheatgrass appears to be advancing north. Crested wheatgrass is said to be more resistant to cheatgrass than are most other grasses. However, that just means that it takes longer to succumb. At this point, it appears likely that the cheatgrass will ultimately eliminate other plants in this spot.This is one of a series of photos with pictures and information about cheatgrass.
