VALUE AND USE
SPECIES: Elymus lanceolatus | Thickspike Wheatgrass
WOOD PRODUCTS VALUE :
NO-ENTRY
IMPORTANCE TO LIVESTOCK AND WILDLIFE :
NO-ENTRY
PALATABILITY :
The palatability of thickspike wheatgrass to cattle is good in the
summer and fair in the winter. Palatability of this grass to elk is
good yearlong; palatability to deer is fair in the spring [40].
The degree of use shown by livestock and wildlife species for thickspike
wheatgrass in several western states is rated as follows [14]:

NUTRITIONAL VALUE :
Compared to other grasses, thickspike wheatgrass is rated good in energy
value and fair in protein value [14].
COVER VALUE :

VALUE FOR REHABILITATION OF DISTURBED SITES :
Due to its drought tolerance and ability to form a dense sod, thickspike
wheatgrass and cultivars of it are widely used for soil stabilization on
disturbed range sites and dry areas subject to erosion, as well as on
roadsides, airports, irrigation canal banks, recreation areas,
construction sites, abandoned farm lands, and planting corners where
circle move sprinklers are used [2,32,36].
The cultivar 'Critana' is adapted for use in Montana, Wyoming, and the
western Dakotas in areas with mean annual precipitation of 10 to 16
inches (25-40 cm). It has been successfully used on mine spoils and in
range seedings in Montana and Wyoming [35]..
The cultivar 'Sodar' is widely used as a low-growing, low-maintenance
cover in the Intermountain area. It is used for roadside seedings,
recreation areas, disturbed areas, and other sites where a
low-maintenance turf is desirable [35].
Vesicluar-arbuscular mycorrhizae are a common component of arid soils.
They usually increase nutrient and water intake, as well as increase the
dry mass of plants. The disturbance of land often leads to the
reduction or elimination of mycorrhizal fungi propagules. Water
relations in thickspike wheatgrass plants are not affected by
inoculation of mycorrhizae or the presence of annuals [1].
OTHER USES AND VALUES :
Although thickspike wheatgrass is often seeded alone, it is also seeded
in mixtures for cover and forage. In mixtures with taller species, it
is sometimes used as a spreading undercover plant [15,40].
Cultivars with good seed production and high seedling vigor include
'Sodar,' released in Idaho and Washington, 'Critana,' released in
Montana, and 'Elbee,' released in Alberta [18,30,34]. Commercially
available seeds of thickspike wheatgrass were used successfully to
revegetate subalpine slopes of Montana ski areas [6].
MANAGEMENT CONSIDERATIONS :
Weed control is usually needed on new seedings of thickspike. Stands
should not be grazed until plants are firmly rooted. In the sandy soil
where thickspike wheatgrass usually grows, trampling damage is often as
serious as overgrazing. Livestock should be managed to prevent overuse
and subsequent wind erosion problems. As soil becomes stabilized and
plants get older, yields tend to decrease [32]. When seeded alone, a
fertilization program helps to maintain high forage production [40].
