Within each area is an identifying symbol or •• - •~'~ <br />name. The following symbols are shoim on your map: ~'~' <br />Symbol or Site Name Generalized Descriptions <br />Range Site Descriptions (Detailed descriptions are available in <br />your Soil Conservation Service office,) <br />Pinyon Juniper Pinyon-Juniper type woodland occurs at Che lowest elevations of the <br />Woodland (P.J.) coniferous woodlands types in Colorado. Elevation will range from <br />5000 to 7000 feet and annual precipitation will average from 12 to <br />15 inches. Grazing is pretty much controlled by the density of the <br />ground cover. Dominant grasses are blue grams, galleta, sedges, <br />Indian rice grass and June grass, while the cominant shrubs are <br />oak, mountain mahogany, service berry and wild rose. <br />Loamy Foothills Early spring moisture occuring on medium to slightly clayey soils <br />(L.F.) with moderate permeability and fair water holding capacity makes <br />this site excellent .for productive plant growth. Production reaches <br />as high as 1500 lbs. per acre air dry in favorable years. Midgrasses <br />mainly needle grasses and western wheatgrass - dominate with warm <br />season grasses such as little bluestem and sideoats grams becoming <br />increasingly impor*,ant in warmer areas. The understory is blue <br />Arama, June grass, and r.a*.ive bluegrasses. Tall rabbit brush and <br />oakbrush tend co invade this site. <br />ShalJ.ow FootY~ills Shallow ~~oils occurring on ridges, hogbacks, and steep slopes, <br />(5.~.) with limited capsciry to hold a sufficient amount of moisture limit <br />~~od forage production on this site. Production usually does not <br />exceed SOJ lbs per acre sir dry even in favorable years. The aspect <br />of r_his site is that of browse, with mountain mahogany being the <br />p ri.nc ipal species. Thn hluestems, pi~iyon pine, juniper, or <br />ponderosa pine may be pi•esu.it. <br />Rocky Foothills Early spring moisture occurring on moderately deep to deep rock <br />(I;.F.) fii'_ed stony loam soi!.=_, ~i~ae this site a good potential for prod- <br />uctive plant growth. Rocks tend to concentrate the moisture in a <br />given volume of soil, increasing the water available for plant <br />growtih over that in a rock-free soil. Production reaches as high <br />as 1500 lbs. per acre air dry in favorable years. Bluestems, <br />Griffiths wheatKras~, sideoats grans, needle a1;,3 ~hread along e:ith <br />a scattered stand of skL~:ikbush, mountain mahogany, and currant, <br />form the typical aspect. <br />Ponderosa Pine Soils are modera±ely deep of various textures, and may have con- <br />(P.P.) siderable stoniness. Prer_ipitation is 16 inches or higher. This <br />site has a crown canopy averaging less than 50%. Enough light <br />gets through to prod~ice considerable understory vegetation. The <br />pcte;itial understory con.^,i•st:; of a grass, forb and shrub mixture. <br />Arizona fescue, mountain muhly, slender wheat grass and little blue <br />stem often dominate the community. Snowberry, mountain mahogany <br />and oak brush are scattered throughout this site. <br />
