Of these, Indian rice grass <br /> composed from 20 to 408 of the vegetative cover, blue grama <br /> grass 10 to 308, and pinyon 5 to 208. Readily observed <br /> plant species which composed less than 58 each of the vege- <br />~ <br />, ti <br />t <br />t <br />ib <br />f <br />l <br />b <br />k <br />h <br />~ a <br />ve cover were wax curran <br />, r <br />es cereum, <br />a <br />se <br />uc <br />w <br />eat, <br />' eriogonum sue, sage, artemesia frigida, and cacti, opuntia, <br /> species. Three distinct stories of vegetation were apparent. <br />' The pinyon reached to a maximum of 15 feet, while the currant <br /> and false buckwheat ranged to a maximum of 6 feet and 2 feet <br />' Y.all, respectively, and the grasses ranged up to 12 and 20 <br /> inches in height for blue grama and Indian rice grass, respec- <br /> tively. <br /> According to the U.S. Soil Conservation Service, other <br /> plant species which are associated with soils identified in <br />i , this area are needle and thread, stipu comatu, and bunch <br /> bluegrass, poa ~. These species may be more evident during <br /> <br /> the growing season. <br /> Approximately 758 of the area is classified as San Isabel <br /> stony sandy loam by the Soil Conservation Service. Soils of <br />' the San Isabel series are shallow, 5 to 20 inches deep, over <br /> gravel and cobbles.
