c. If ecological retr-~igr-essior~ is cattle ar elk induced,
desirable grasses decrease. Under continuous early spring
grazing, wester-r~ wheatgr-ass, mountain rnuhly, and '
r~eedleandthr-ead will decrease relatively fast. Bottlebr-ush
squir-r-eltail, ar~d blue gr-ama will initially increase, but
with continued r-etragression long grazing, these taa will
decline giving r-oorn far- an increase in ring rnuhly and
ir~vasior~ by sleepy grass.
With r-etragr-essian, winter-fat quickly declines and
disappears. Other shrubs and half shrubs, such as rubber
rabbitbr-ush, and gray hc~r-sebrush increase along with far-bs
such as Cir-egor~ f I eabane, p i ague hyrnena>;ys, Nebraska I up i ne,
Dr-urnrnar~ds rni Il:vetch, shur-ts rni Il:vetch, senecio species, and
sulfur buckwheat.
e. Ar~r~ual F'r-oductior~
Tf the range is ire e>;cellent condition, the approximate total
annual pr-oducti~in (air-dr-y) is:
favor-at~le years 1060 pounds/Ac 1177. Kg/Ha
nar-mal years =;UC1 pounds/Ac 896.8 Kg/Ha
ur~favor-able years c•00 pounds/Ac 672.6 Y.g/Ha
Of this production 6 - 10 percent will likely be unpalatable
ar- out ~~f reach to grazing animals.
