Idaho <strong>Fescue</strong> - <strong>Foothills</strong> Rough <strong>Fescue</strong> - June Grass FFA13<br />
(Festuca idahoensis - Festuca campestris - Koeleria macrantha) Herbaceous<br />
n=9 This is a late seral plant community in the <strong>Foothills</strong> <strong>Fescue</strong> grassland on gravel range sites<br />
associated with the Rinard soil series. The reference plant community for this range site is likely dominated<br />
by rough fescue but the area of the gravel range site is very small in the <strong>Foothills</strong> <strong>Fescue</strong> Subregion.<br />
Moderate to heavy grazing pressure will increase the abundance of Idaho fescue along with other grazing<br />
resistant grasses like June grass, sedges and wheatgrass species. Due to the aridity of the site, this range<br />
site is likely more resistant to invasion from Kentucky bluegrass and Timothy than most loamy range sites.<br />
<strong>Range</strong> recovery is expected to be very slow, since gravel-based soils are shallow and drought prone. Note<br />
that the exposed soil and moss/lichen cover is much higher and total vegetation cover much lower than for<br />
rough fescue plant communities that have developed on loamy range sites.<br />
Soil Exposure: 11 % (0-19) Moss/Lichen Cover: 21% (0-45) Total Vegetation: 77% (55-91)<br />
