WESTERN WHEATGRASS: Agropoyron smithii
|
Western wheatgrass is a cool-season native perennial sod-forming grass. It
has a deep fibrous root system with vigorous rhizomes that effectively
protect the soil from wind and water erosion. It is a major rangeland
species in the northern and central Great Plains. Western wheatgrass is
widely adapted to varying soil and climatic conditions. Where soil is
favorable and moisture plentiful, western wheatgrass may be found in nearly
pure stands. On upland sites it is commonly found in association with the grama grasses. |
|
Western wheatgrass starts growth early in the spring and produces a high
protein forage relished by all classes of livestock. Plants at maturity
attain a height of two to three feet. This grass goes dormant during the
hot/dry months, but makes further growth in early fall. Established stands
of western wheatgrass can endure long periods of severe drought, tolerate
flooding, soil salinity, poor drainage, and withstand heavy grazing
pressure. |

USE AND
MANAGEMENT:
Widely
used for pasture and hay, western wheatgrass is also an excellent grass for
erosion control, critical area stabilization, grass-lined water channels, and
surface mine reclamation.
Well
suited to intensive grazing systems, western wheatgrass provides high quality
forage when the warm-season natives are at their worst. For maximum production
on rangeland, defer grazing every few years at least 90 days before seed heads
exert. Protect this grass from grazing throughout the growing season if it is
managed for seed harvest or hay. Graze only moderately during the dormant
period.
