Vegetation Site Description <br />Ftiink and Hooker Pi t <br />I. Vegetation Site Name - Stony Loam <br />A. Climate - Precipitation averages 15 to~20 inches per year. Over <br />half of the pr~ripitation comes as snow. The optimum growing <br />season is May 1 to July 1. <br />B. Elevation and Topography - The site occurs on steep to moderately <br />steep slopes at the site. Elevation is about 6,450 feet. , <br />C. Soil - Mapping unit 102 is classified as a terrace escarpment. <br />It is a complex consisting of the Perma and Hesperus series. <br />It occupies very steep breaks between terraces ar_d upland <br />areas. It is a well drained soil with a very stony loam <br />surface about 10 inches thick. The underlying material is <br />very stony sand to 60 inches or more. There is 50 to 70 percent <br />cobble and stone throughout the soil. <br />D. Potential Plant Community - Stoniness on and within the soils <br />make for conditions quite favorable for the growth of plants. <br />Stones act to make soils warmer and they work to make available <br />an amount of water which could be limited in a stone-free soil. <br />Wheatgrasses, Indian ricegrass, bluegrasses, mountain muhly <br />and other grasses are mixed with bitterbrush, serviceberry, <br />bie sagebrush, and snowberry to combine with a number of forbs <br />in the production of as much as 2,000/acre in a favorable year. <br />E.
