Agropyron cristatum (crested wheat grasscrested wheatgrassfairway crested wheat grass) is a species in the Poaceae family. This plant is often used as forage and erosion control. It is well known as a widespread introduced species on the prairies of the United States and Canada.

Agropyron cristatum is one of several closely related grass species referred to as crested wheatgrass. It is unable to hybridize with its similar relatives, as it is a diploid species, whereas its closest relative, Agropyron desortum, is a tetraploidal species.

It was introduced from Russia and Siberia to North America in the first half of the twentieth century, and widely used to reseed abandoned marginal cropland undergoing varying degrees of soil erosion and secondary succession

A. cristatum is very long lived, with stands often remaining productive for 30 years or more

REGENERATION PROCESSES: 

Crested wheatgrass reproduces by seed or vegetatively and is self-sterile. Crested wheatgrass seedlings are very hardy, vigorous, and easily established. The seeds of crested wheatgrass germinate well throughout a range of temperatures, allowing the plant to spread rapidly. Crested wheatgrass produces tillers, and its ability to spread vegetatively contributes to its presence at higher elevations, where the growing season may not be long enough each year to produce seed. However, in drier habitats, the ability of rhizomatous native grasses to propagate without setting seed allows them to compete well with crested wheatgrass. Crested wheatgrass is able to emerge from a relatively deep soil depth, which allows it to escape the more extreme environmental soil conditions closer to the surface. Crested wheatgrass shoots have long, numerous, and quick-growing roots, which may explain strong seedling establishment.
