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. == History == ''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.〔Hanson, A.A. 1972. Grass varieties in the United States. USDA Agricultural Handbook No.170〕 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.〔Rosiere, R.E. Publication year unknown. Introduced Forages. Tarleton State University, Stephenville, Texas. Retrieved 14 November 2011 from http://www.tarleton.edu/Departments/range/Grasslands/Introduced%20Forages/introducedforages.htm〕 ''A. cristatum'' is very long lived, with stands often remaining productive for 30 years or more.〔McLean, A., and A.L. van Ryswyk. 1973.
