<br />0. Vegetation <br />1. Terrestrial Flora <br />Four primary vegetative types are found within the lease <br />boundary of lease applications C-22644 and C-26913: <br />grassland, sagebrush, mountain shrub, and aspen; there <br />is one subtype - mountain shrub-rock outcrop. <br />Grassland, type 1 <br />A few isolated stands of grassland type are found in the <br />area; they are mostly small parks among the mountain <br />shrub and aspen types. <br />The vegetation consists primarily of needlegrass (Stipa <br />spp.), bluegrass (Poa spp.), and bromes (Bromus spp.). <br />Many very small areas of grassland type occur along the <br />creek bottoms, but have not been mapped separately from <br />the surrounding vegetation. <br />Sagebrush, type 4 <br />Sagebrush community occurs on all sltes below the ele- <br />vational range of mountain shrub community; the trans- <br />ition zone between the two communities is often very <br />wide, making them difficult to separate. The sagebrush <br />is often short in the bottom lands, and these areas <br />support a good understory of grasses and forbs. <br />The dominant grasses associated with the sagebrush (Ar- <br />temesia spp.) are: wheatgrasses (Agropyron spp.), blue- <br />grasses, June grass (Koleria cristata), and bottle brush <br />squirreltail (Sitanion hystrix); dominant forbs include <br />113 <br />
