Discussion

Nardus stricta is a widespread xerophytic and glycophytic species in Europe, usually growing in open areas on sandy or peaty soils. In the Flora region, it is found in scattered locations from upper Michigan to Newfoundland and Greenland, and in Oregon and Idaho, where it is listed as a state noxious weed. The stiff, sharp leaves make it unpalatable; hence it tends to survive in areas of heavy grazing. This, combined with its broad ecological range, makes its potential for spreading in western rangelands a matter of concern.
