r a i? r? i i 0 , RANGE SITE NO. 31 Page 3 SANDY BOTTOMLAND August 1975 , soil. a. The•.soils are` usually deep but may be shallow and underlain by t' clean sand or gravel. They vary in texture from sandy loam to r`. loose sand.The%sandy texture with its faster Intake, deeper penetration and more ready release of moisture than heavier soils,.,is the'principal factor affecting plant growth. However, extra moisture allows significantly higher production than other sandy sites and offsets to some extent the moderate to low water holding capacity.. Consequently, the vegetation is a mixture of tall and midgrasses with the tall grasses typical of slightly more moist locations predominating. In general, the salt concen- tration is not strong enough to seriously affect climax vegetation, ' but.it may cause such species as saltgrass to become abundant when the range is misused. A lower moisture content in the upper foot'or two of soil often makes the effect of salts more pronounced than'on adjacent wet meadows. The site is not highly erodible, but is subject to severe wind damage If denuded, b.
