NEED IN SITU PHOTOS. Canada wildrye, a tussock grass abundant in the Great Plains, has been recorded from the Watershed in only a few, diverse locations: by the Rio Grande as it passes through the Pinyon Hills (Conejos Co, 1987), by Hwy 160 seven miles west of Del Norte (Rio Grande Co, 1976), one mile west of Summitville in a subalpine meadow (Rio Grande Co, 1976). Elymus canadensis has been used for soil stabilization and highway restoratioin, which may account for some of these records. Shaw (2008), however, says that the species has been recorded road side and in moist areas "at lower elevations and up to the foothills over Colorado." In the USA, the species grows, sometimes abundantly, in all states except for those of the Pacific coast and the Deep South. It follows the Rio Grande drainage through New Mexico down to and including the Big Bend region of Texas. Note that the symbiotic relationship E. canadensis has with microrhizae has been much studied.
