The state grass of Utah, Indian Ricegrass is high in protein and was used by various indian tribes to make flour.

It is one of the more widely adapted native grasses of the intermountain west rangelands. It is drought tolerant and found on most range sites. It grows at elevations between 3,000 and 10,000 feet and is dapted to a wide variety of soils. It most frequently occurs in sandy, gravelly, and shallow soils in the upland and semi-desert climatic zones and is frequently found in dunes. It does not do well on wet or poorly drained soils. It is also adapted to soils high in lime. It is moderately salt and alkali tolerant.

Indian ricegrass is a key species on Utah foothills and semi-desert range. It is one of the more valuable grasses for domestic livestock and big game animals, providing excellent forage for spring and summer use. It is especially valuable for winter grazing because the plants cure well and lower plant parts remain somewhat green. Due to the abundance of plump, nutritious seed, it is an excellent food source for upland game birds, particularly mourning doves, pheasants and others. The seeds are high in protein.

Indian Ricegrass is a very valued and desired species for wildlife habitat improvement, disturbed sites, mine reclamation and range mixes.
