' Rocky Foothill Range Site (Sy)
This range site consists of well drained and some-
what excessively drained soils that have a cobbly
' sandy loam to clay loam surface layer. Shale and
bedrock are at a depth of 10 to 30 inches. Slopes
are 9 to 65 percent. Annual precipitation is 15 to
19 inches. Permeability is moderate to slow.
Big and little bluestem, mountain muhly, spike
muhly, sidcoats grams, prairie sandreed, and blue-
bunch wheatgrass are the most important plants.
Desirable forbs that decrease during the initial
. stages of range deterioration are mountain sunflower,
spiderwort, and littlepod vetch. Scattered ponderosa
pine are also common.
Such shrubs as Gambel oak, mountain-mahogany, wild
' currant, and squawbrush are the most noticeable
plants that increase as range condition deteriorates.
Bitterbush occurs in places. Other plants that
increase as range condition declines are blue grama,
' Kentucky bluegrass, needle-and-thread, sandberg
bluegrass, squirreltail, three-awn, dryland sedge,
fringed sagebrush, hairy goldaster, and wormwood.
Following prolonged overgrazing, sleepygrass,
' Russian knapweed, snakeweed, and such annuals as
cheatgrass, kochia, lambsquarters, and wild mustard
invade this site.
Deferring grazing in summer and early in fall
' favors big and little bluestem, side-oats grama,
and mountain muhly and improves range condition.
The total annual acre yield of vegetation where
this site is in excellent condition is 1,600 pounds
' air-dry weight in favorable years and 800 pounds in
less favorable years. approximately 70 percent is
for plants that provide forage for domestic livestock
