<br />the species have their origin in western floras. However, several have <br />origins in midwestern and northwestern floras. Some weedy species have <br />invaded from Eurasian floras. <br />3.2.1 Weedy Species <br />Of the 176 species observed, 33 species are considered weedy (Thorton et <br />al. 1974). Two noxious weedy species were observed (quackgrass, and Canada <br />thistle). Of the 33 weedy species 2 were annual grass, 1 was a perennial <br />grass, 10 were perennial forbs, 1 was a subshrub, 1 was a deciduous shrub and <br />1 was a broadleaf evergreen shrub. Many of the weedy species were found along <br />roadsides, around stock ponds, corrals and other disturbed locations. Both <br />quackgrass and Canada thistle were found primarily in the meadow type. <br />3.2.2 Threatened and Endangered Species <br />No threatened or endangered species are known to occur within the <br /> <br />vicinity of the Danforth study area (Colorado Natural Heritage Inventory, <br />1984 personal communication). None were observed during the course of this <br />study. <br />3.2.3 Reclamation species <br />Several of the native species occuring within the project area have <br />commercially available seed for use in reclamation. Of the perennial <br />grasses, western wheatgrass, bluebunch wheatgrass, slender wheatgrass, Indian <br />wheatgrass and big bluegrass have several commercial varieties available. To <br />increase diversity in areas, mountain brome and Great Basin wildrye could be <br />considered. Among the perennial forbs with commercially available seed at a <br />reasonable price is Lewis flax and Rocky Fountain penstemon. Fiore higher <br />priced and not so readily available forb seed includes western yarrow, <br />Louisiana sagebrush, asters, arrowleaf balsam root, Indian paintbrush, <br />10 <br />Exhibit 10, Item 5 <br />15 <br />Revision Date: 03/06/07 <br />Revision No.: PR-02 <br />
