<br />the range is in excellent condition, the total annual yield
<br />of air-drp hcrbago is 1;S00 to °,500 pounds per acre.
<br />SALT MEADOW RANCE SITE
<br />This range sits consists of deep to moderately deep
<br />soils that hai•e a surface layer and subsoil that range
<br />ft•om loamy sand to clay. These soils have a high water
<br />table mid moderate to high salinity. Some areas are
<br />flooded from time to time. In places water-holding capac-
<br />ity is high, but the moisturre may be limited by high wn-
<br />cettt.ration of salts.
<br />11']irot this :ito is in Psrellent rnn.lition, the vegetation
<br />is limiter( tri that tolerant of salts. 1)mninant species are

<br />ages tho groicth of switchgrass, nllrali sacaton, and west-
<br />ern Wheatgrass. tiVhen the rnnge is in excellent condition,
<br />the total anmtal yield of air-dre herb.•lge is 1,800 to 2,500
<br />polmds per nc._,
<br />SANDY MEADOW RANGE SITE
<br />This range site consists of nearly level to gently slop-
<br />ing, deep to moderately deep soils that have a sand or
<br />sand}• lo;un surface layer and subsoil. These soils hate
<br />n high icnfer table and, in places, are slightly to mader-
<br />ateh• saline.
<br />11'hen this site is in excellent condition, the dominant
<br />grasses are tali grasses, principally switchgrass, indiml-
<br />*rass, big blacstem anti, nt the Wetter spots, cordgrnss.

<br />11-ben the range is in excellent condition, the total
<br />annual yield of alr-dry herbage is 1,900 to 2,100 pounds
<br />per Here.
<br />CHOPPY 9ANDa RANCE SITE
<br />This ran_•e site consists of deep, rolling to moderately
<br />steep soil, that bare a surface layer and subsoil of sand.
<br />The soils are dunelike. Loose, shifting sand unprotected
<br />by vegetation makes up as much as 20 to 30 percent of
<br />sumo areas. Capacity for storing moisture and plant
<br />nutrients is IoW, bat the soils are Wetted to considerable
<br />depth by fairly small amounts of precipitation. These
<br />soils are subject to very severe soil blowing Where there
<br />is not Pnou_•h plant cover.
<br />Tall grasses, mainly sandrrerl and sand bhlestem, are
<br />drnninmit When this range site is in exceP,ont. condition.
<br />Other grasses are hairy rams, sand dropseed, '~loWOUt-
<br />grnss, and beardgrass. 5~andhill mutely and yucca gtoW
<br />in mall amounts.
<br />1Vliett the t:'llige is in excellent condition, the total
<br />annual yield of air-dry herbage is 600 to 1,400 polmds
<br />per acre.
<br />LOESS $REAgB RANCE SITE
<br />Olily Colby loam, 9 to 30 percent slopes, eroded, is in
<br />this range site. This strongly sloping to steep soil
<br />has a surface layer of loam and a subsoil that rnn~es from
<br />eery fine sandy loam to silt loam. Capacity for storing
<br />moisture mid plant nutrients is moderate to high, but
