DescriptionBasin wildrye (Leymus cinereus [Scribn. & Merr.] A. Love) is an important perennial, hardy, long-lived, cool season C3 native grass of rangeland plant communities throughout much of western United States and Canada. All classes of livestock and wildlife, including large and small birds and mammals, utilise the grass year round for food and protection due to its 2-3 m tall, stiff stature which pro-vides standing winter cover. Though occurring in precipitation areas of 150-500 mm and elevations of 600 to 3,000 m, it is usually found in deep, well-drained soils of high water holding capacity along drainage areas. Seedling vigour is only fair, and stands may take 2 to 5 years to fully establish. While tolerant of low to moderate levels (<10 mmhos/cm3) of saline and sodic soils and short-term winter or spring flooding, it does not tolerate extended periods of inundation (Ogle et al. 2012). It also does not tolerate heavy grazing or haying in the spring and summer due to its high growing point and minimal regrowth capability, and misuse has caused diminished population density through much of its original range (Anonymous, Utah Farmer-Stockman 1983).
