Idaho fescue is a native, perennial, cool-season grass. Idaho fescue is abundant and sometimes the dominant plant on extensive areas. It usually ranks with the choicest forage plants, and in Montana and possible elsewhere is, everything considered, probably the best forage grass. However, it may not quite merit first rank in palpability in some areas.

The range of Idaho fescue extends to California, Colorado, Idaho, Montana, Nevada, Oregon, South Dakota, Utah, Washington, and Wyoming. Idaho fescue is one of the most common and widely distributed grasses in the Western States. However, it is either rare or absent in the southern portions of the western states.  Idaho fescue habitat extends from 1,000 to over 13,000 ft, though most prevalent from about 5,000 to 8,000 ft.

Idaho Fescue grows on all exposures and under a wide variety of soil conditions. It prefers silt loam or sandy loam soils and is occasionally found on loamy sand soils. Exposed benchlands, hillsides and ridges, parks, meadows, forestlands, and open ponderosa and lodgepole pine stands are common habitats. Idaho fescue is tolerant of weakly saline, weakly alkaline and acidic soil conditions. It has excellent cold tolerance, moderate drought tolerance, and moderate shade tolerance. It is not as drought tolerant as sheep fescue and its drought tolerance is similar to that of hard fescue. It is not tolerant of high water tables or flooding. Its frequent associates include bluegrass, mountain brome, geranium, yarrow, mountain sagebrush, antelope bitter brush, ponderosa pine, bluebunch wheatgrass and slender wheatgrass.

Idaho fescue is a fair to good forage for all types of domestic livestock. It is good year-around forage for elk and is grazed in spring by deer. Idaho fescue matures later in the growing season than most other range plants. Therefore, it is particularly useful for late season grazing. All classes of livestock relish it in the spring, as well as later in the season where it grows on north slopes or in cooler, moister sites and where the herbage remains tender. Idaho fescue is susceptible to overgrazing and will succumb to continued grazing abuse.

Idaho fescue is fairly drought resistant, stands are persistent and it is adapted to stabilization of disturbed soils. It produces an extensive, deep root system an is excellent for erosion control. It does not compete well with aggressive introduced grasses. Its drought tolerance, combined with extensive root systems and good seedling vigor, make this species ideal for reclamation in areas receiving 14 to 20 inches annual precipitation.

Idaho fescue initiates growth in March through April and matures in mid to late summer. With adequate moisture, Idaho will produce a moderate amount of re-growth following seed maturity. Late fall plantings are most successful. Plant early in the spring if fall planting is not possible. Seeded stands require 2 to 3 years to establish, but are very competitive once established. Recommended planting depth is 0.25 to 0.50 inches
