Northslope Quercus-Cercocarpus Community - This community <br />' is similar to the one described above, but is much more <br /> common and dense. It also exhibits a strong preference <br />' for rocky soils of the Newlin Series. hoisture no <br /> doubt prod uces much of the additional productivity <br /> bec <br />f th <br />th <br />f <br />i <br />It <br />i <br />i <br />t <br />h <br />ht <br /> ause o e nor <br />- <br />ac <br />ng aspec <br />s max <br />mum <br />e <br />g <br />. <br />' is about 1 2 feet. Of interest are the dense clumps of <br /> Snowberry that tend to surround the Oakbrush stands. <br /> <br /> 6. Bottomland Bromus-Convolvulus Community - This community <br /> mainly is restricted to shallow drainage systems where <br /> additional moisture produces more growth on the <br />' productive Buick soils. Productivity at present is <br /> about 500 lbs. per acre, but probably has a potential <br />1 <br /> of 1000 to 1200 lbs, per acre in good years when in <br />' good condi tion. Cover approaches 75~ with a height of <br /> about 12". There is no upper synusium. <br />7. Agropyron-Stipa Community - This poorly represented <br />' community is by far the most productive site. It is <br />found only on the Sampson loam near the north boundary <br />' of the quarter section. Several wheatgrasses dominate <br />' the site with Stipa viridula and S. comata also being <br /> <br />- 35 - <br />
