The soils on the proposed gravel pit site correlate with two distinctive
range sites. ( A range site is a distinctive kind of rangeland that dif-
fers from other kinds of rangeland in its ability to produce a character-
istic natural plant community.) These range sites are Sandy bottom land
(soils 29-AB), and Salt meadow (soils 34).
I ' I Range Sites
Sandy bottom land: The potential native vegetation for this site has a
definite tall grass appearance, dominated by Switchgrass, Indian grass,
Prairie sandreed and Sand bluestem, with smaller amounts of various mid-
grasses such as Side-oats grama, Little bluestem, Needle-and-thread and
i., ~3 Canada wildrye that are scattered throughout. The ground cover is about
40%. The expected annual production in favorable years could be 2,500

Salt meadow: The potential native vegetation for this site is Alkali saca-
ton, Switchgrass, Western wheatgrass, Sedges, Alkali bluegrass and Slender
wheatgrass. Other grasses are Canada wildrye, Foxtail barley, Vine mesquite,
Prairie cordgrass and Rush. Cottonwoods and Willows occur along the river
bottom. The ground cover is about 50% or more. With an expected annual
production in favorable years of 3,000 pounds (air dry).
