c. If ecological retrogression is cattle-induced, desirable grasses
will decrease. If retrogression !s sheep-induced, desirable
fortis and shrubs will decrease. Side-oats grams, and little
bluestem will decrease while galleta and blue grams increase.
Bigelow sagebrush tends to increase as the desirable grasses are
reduced. Plains pricklypear, broom snakeweed, green plume
rabbitbrush, small soapweed, red th;eeawn and sand dropseed will
dominate the site ae retrogression proceeds.
d. Vegetation densityl/ is approximately 20 percent.
l/ Vegetation density = basal area. This is the area of ground surface
covered by the perennial stem or stems. Usually, this is measured one
inch (2.54 cm) above the soil in contrast to the full spread of perennial
foliage.
4. Annual Production
If the range is in excellent condition, the approximate total annual
production (air-dry) is:
favorable years 1,600 pounds/Ac 1,814 Kg/Ha
normal years 800 pounds/Ac 907 Kg/Ha
unfavorable years 400 pounds/Ac 454 Kg/Ha
Of this production 15 percent will likely be unpalatable or out of
reach to grazing animals.
