• Riparian Woodland. This vegetation type occurs at three (3) locations <br />within the Southfield mine area. The primary Riparian Woodland vegetation <br />area extends the entire length of the Southfield mine area from west to <br />east along Newlin Creek as shown on the Mine Area Vegetation Map, (Map <br />16). A second Riparian Woodland area is located in the southwestern <br />portion of the mine area, along a streambed as shown on the Mine Area <br />Vegetation Map, (Map 16). The third Riparian Woodland area is located in <br />the northeastern portion of the mine area, along another streambed as <br />shown on the Mine Area Vegetation Map, (Map 16). The Riparian Woodland <br />vegetation type is characterized by several tree species with narrow leaf <br />cottonwood, ponderosa pine and wild plum dominating. Other species common <br />to the Riparian Woodland type include, one-seeded juniper, boulder <br />raspberry, snowberry, oak brush, common gooseberry and wax current. <br />Ponderosa Pine-Pinvon-Juniper Woodland. The majority of the Southfield <br />mine area is occupied by this vegetation type. This vegetation type is <br />• characterized by dense stands of ponderosa pine on north facing slopes and <br />dominant stands of one-seeded juniper on east and south facing slopes. <br />Additional tree species associated with this vegetation type include <br />pinyon pine which is found throughout the area, oak brush, skunk brush, <br />mountain mahogany and snowberry. The grass species most commonly <br />associated with the Ponderosa Pine Pinyon-Juniper Woodland vegetation type <br />within the Southfield mine area include blue grama, western wheatgrass, <br />needle and thread, squirrel tail, mutton grass and red three-awn. The <br />Mine Area Vegetation Map (Map 16), illustrates the occurrence and <br />distribution of this vegetation type. <br />Grassland. The Grassland vegetation type typically occurs along the top <br />of ridges and mesas within the Southfield mine area. These areas are <br />dominated by blue grama and ring muhli. Numerous other grass species such <br />as side oats grama, red three-awn, squirrel tail, western wheatgrass, sand <br />drop seed and little blue stem are common in this vegetation type. Also <br />present in substantial numbers are forb species including several species <br />• of cactus, snakeweed and sagebrush. Generally this vegetation type is <br />also characterized by scattered ponderosa pine, pinyon pine and one- <br />seeded juniper. <br />2.04.10-2 <br />
