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 desertorum, is a tetraploid 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.
