Exhibit J CMLRR 112 Permit Application <br />Agile Slane Systems, Inr. <br />dominant species include tamarisk, plains cottonwood (Populus sargentii), peach-leaf <br />willow (Solix amygdaloides), and rubber rabbitbrush. Since this vegetation type is not <br />proposed to be disturbed, no [ransects were located. The potential production of native <br />understory vegetation was not rated for this type by the SCS. The forage production <br />potential of this unit is assumed to be negligible. <br />3.5 Grassland Vegetation Type <br />Dominant species within this vegetation type include blue grama, tree cholla <br />(Cylindropuntia imbricata), and kochia where soils aze disturbed by livestock. Transect <br />number 8 was selected to represent this vegetation community in the proposed facility <br />azea south of Tallahassee Creek. Slopes were neazly level. Total plant cover was 30.7 <br />percent while baze ground was 66.2 percent. Litter and rock contributed 3.2 percent <br />ground cover. The potential production of native understory vegetation in normal years <br />is typically 1,100 pounds per acre of air-dry vegetation (SCS 1995). The soil existing on <br />site has a higher percent of coarse (gravel) fragment content than the soil mapped for the <br />area by the SCS. Therefore the potential production is believed to be approximately 800 <br />pounds per acre for this site. <br />3.6 Pinyon-Juniper/Grassland Vegetation Type <br />This vegetation type occurs to the south of Tallahassee Creek. It is similaz to the <br />grassland type but contains a pinyon 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 peaz, and kochia. The slope is 1 to 2 percent on a southerly aspect. Total plant <br />cover (tansect number 9) was 29.0 percent, cover by litter and rock approximately 5.2 <br />percent, and baze 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 coazse (gravel) fragments in the soil profile on the areas proposed to <br />be disturbed, the potential production is believed to be a maximum of 425 pounds per <br />acre for this site based on a comparison of cover percentages with the grassland type. <br />3.7 Grassland/Improved Pasture Vegetation Type <br />This vegetation type occurs within the permit area south of Tallahassee Creek and to the <br />west of Phase IA in the gravel bar in Phases II and III. The dominant vegetation species <br />in this vegetation type include both native and introduced pasture grasses. Positive <br />identification of vegetation species was not possible due to the eazly spring time of the <br />Feld work and the over grazing impact. <br />3 <br />
