Exhibit B Site Description Mineral Joe Mine Permit Amendment M- 1977 -284 Vegetation Information The pinon juniper woodland at the site consists of approximately 30% to 50% pinon pine, and 50% to 70% Utah juniper. Most stands are not more than 20 feet tall, although some individuals may reach 35 feet. The tree canopy covers about 25% to 30 %, understory covers about 10 %, and the remaining ground is bare. The average annual production of understory vegetation is about 400 to 500 pounds per acre. The pifion juniper woodland typically corresponds to soil map unit symbols 23- Bodot, dry-Ustic Torriorthents complex and 75-Pifion-Bowdish-Progresso loams. The sagebrush park areas have an average ground cover of 40% with the remaining soil bare. The grasses range in height from six inches to 24 inches. The height of the sagebrush ranges from one foot to four feet. The average annual production is 1,100 pounds per acre. The sagebrush park areas typically correspond to soil map unit 60- Monogram loam. A more detailed review of the vegetation on the Mineral Joe permit site is provided in Exhibit T — EPP.
