Parkdale Project • 5 • Reclamation Permit <br />2.6 Pinyon-Juniper/Grassland Vegetation Type <br />This vegetation type occurs to the south of Tallahassee Creek. It is similar to the <br />grassland type but contains apinyon-juniper component and a higher percent of cover by <br />tree cholla. Dominant species include one-seed juniper ,blue grama, tree cholla, plains <br />prickly pear, and kochia. The slope is 1 to 2 percent on a southerly aspect. Total plant <br />cover (Transect number 9) was 29.0 percent, cover by litter and rock approximately 5.2 <br />percent, and bare ground was 65.8 percent. Average tree heights were 12 feet and shrub <br />heights averaged approximately 2.5 feet. Transect number 6 was run along the disturbed <br />floor of the existing sandstone quarry. <br />The potential production of native understory vegetation in normal years is typically <br />1,100 pounds per acre of air-dry vegetation (SCS 1995). Given the amount of rock <br />outcrop present and coarse fragments in the soil profile on the areas proposed to be <br />disturbed, the potential production is believed to be a maximum of 425 pounds per acre <br />for this site based on a comparison of cover percentages with the grassland type. <br />2.7 Grassland/Improved Pasture Vegetation Type <br />This vegetation type occurs within the permit area south of Tallahassee Creek and to the <br />west of the proposed permit disturbances. No transects were run in this vegetation type <br />since no disturbances are planned under this permit. The dominant vegetation species in <br />this vegetation type include both native and introduced pasture grasses. The vegetation <br />was in a condition, due to the time of year and the effects of grazing, that positive species <br />identification could not be made during the field sun~ey. <br />
