EXHIBIT J VEGETATION INFORMATION (cont) <br /> Rangeland - Most of the amended acreage south of the current <br /> mine was used as pasture for grazing livestock. On the areas that <br /> were not disturbed by mining the vegetation consists of mostly <br /> grass with some cactus and sagebrush. Average annual production <br /> is approximately 1, 000 pounds per acre. The plant community is <br /> 80 to 90 percent grasses and 10 to 20 percent cactus and sage <br /> brush. This area has a good grass cover because the site has not <br /> been grazed for quite some time. <br /> The species of vegetation found on the site are Blue grama, <br /> Gallate, Western Wheatgrass, Sand dropseed, Buffalograss, and <br /> Sideoats grama. These grass species makeup 85% to 90%, by <br /> weight, of the vegetation found on the site. <br /> Disturbed Areas - Disturbed areas consist of the areas that are <br /> stripped or being mined under the current DBMS Permit (M-2009- <br /> 027) and parts of an old mine area disturbed pre-1976 . Disturbed <br /> areas also include the sand and gravel processing plant areas, <br /> aggregate stockpile areas, internal haul roads . Weed species <br /> occur along the edges of the fields and along roads and temporary <br /> access roads that have not been historically controlled. <br /> Between the current mining area and the County road is an <br /> area that was mined sometime in the past . It appears that <br /> whoever mined the area worked the face of the deposit back from <br /> the County road until their project ended. We suspect this area <br /> was mined to provide material for I-25 which lies 1 . 5 miles east <br /> of the mine . This area has no topsoil on it and the vegetation <br /> has more cactus and sage brush then the surrounding rangeland. <br /> Average annual production is approximately 300 pounds per acre. <br /> The plant community is 60 to 75 percent grasses and 25 to 40 <br /> percent cactus and brush. <br /> The species of vegetation found on the old mine site are <br /> Blue grama, Western Wheatgrass, Sand dropseed, Little Bluestem, <br /> Indian rice grass, Sideoats grama, Various species of cactus and <br /> sagebrush. The grass species makeup 60% to 70%, by weight, of <br /> the vegetation found on the site. <br /> No rare, threatened or endangered plant species are known to <br /> occur in the permit area. <br /> WSG- Hribar Pit Amendment 58 December 2020 <br />
