[Wikipedia] Uses: The tolerance of this grass to alpine climates makes it a good plant to use in revegetating disturbed land in such regions.[8] It's known to respond to burning with increased growth.[7] It is known to spring up on sites where few other plants can grow, such as abandoned coal mines and soils polluted with sulfur, copper, and nickel.[8] Prior to flowering, cattle, sheep, and horses readily consume it; it is also occasionally consumed by wild animals and after flowering by livestock.
