• buildings end the accompanying disturbances associated with confinement <br />of domestic livestock to small areas. See Figure 3.1-1. <br />The proposed project would affect the hayfields and pastureland and <br />produce some disturbance in the native vegetation types. See Table 3.1-1. <br />Each of these vegetation communities was sampled per the direction of Colo- <br />rado Mined Land Reclamation personnel. <br />The Pinyon-Juniper Woodland end Rubber Rabbitbrush Shrubland ere <br />described in the following sections from quantitatively derived data. All <br />other vegetation types ere qualitatively described from extensive field <br />observation and published literature. <br />3.2 Vegetation Types <br />3.2.1 Pinyon-Juniper Woodland <br />A Pinyon-Juniper Woodland occurs on the mountainous terrain <br />north of the Crystal River Ranch buildings. Habitat here is characterized <br />by a topography that is dissected by draws end drainages and has steep slopes <br />in all compass directions. Soils ere shallow end rocky. See Figure 3.2.1-1. <br />• Cover <br />The Pinyon-Juniper Woodland is distinguished by a relatively <br />dense growth of trees, a diverse but sparse shrub stratum, and a sparse <br />herbaceous understory dominated by grass. <br />Forty-four species were identified in the vegetation Type. <br />These include: 2 trees, 8 shrubs, 11 graminoids, 19 forbs, end 4 succulents. <br />Total vegetation cover is 51.3 percent. Trees ere the overwhelmingly <br />dominant life form with 41.0 percent cover. Graminoids, although sparse, <br />are the major constituent of the understory with 5.3 percent cover, followed <br />by shrubs 12.7 percent cover) end forbs (1.7 percent covert. A succulent <br />(Opun#.i.a ~Cicaai..Gi~~l accounted for 0.7 percent cover. Litter accounts <br />for 21.0 percent, rocks 15.0 percent, and soil 12.7 percent cover. See <br />Table 3.2.1-1. <br />Pinyon pine and Rocky Mountain juniper are the dominant tree <br />species providing 34.0 and 7.0 percent cover, respectively. Shrubs are <br />present in the understory as isolated individuals. No one shrub is <br />particularly dominant. The sparse shrub cover is composed of Saskatoon <br />serviceberry Am¢.Lanchien alni/_v.Li.a, big sagebrush, mountain snowberry <br />Siyriphoucaicpv~ oaeophiLu~, and mountain mahogany Cencocaicp~u.~ mvn.#an~~. <br />Other shrubs consist of fringed sage A2#emyia f~eigi~a, winterfet <br />Kza.~cheni~vtihvvia .Lana,ta, Gambel oak Que~rc~ gambe.Ci.i., end skunkbrush <br />Rhin anvma.Li_ca. Shrubs are generally more common in drainages than on <br />slopes. <br />• <br />-fJ- <br />
