Native and Exotic. Used as a pasture grass for wet areas it spreads to choke streams and prevent the establishment of woody riparian species. Catling and Carbyn (2006, Canadian Field Naturalist 120, No 3 pp 307-312) supply a key to separate the non-native subspecies (australis) from the native subspecies (americanus). The native subspecies has reddish basal internodes and the longest lower glume is 3.8-7mm long. The non-native subspecies has pale yellow basal internodes with shorter lower glumes (the longest from 2.6 to 4.2 mm).
