Keenesburg Mine 2014 Vegetation Monitoring Report <br />5.2.3 Species Composition <br />A total of seven life forms and 19 species contributed to the cover data (Table 4) and 30 species <br />were encountered along the transects (Appendix A). Of the species contributing to the cover <br />data, 12 were grasses and seven were fortis, 16 were native and three were introduced (Table 6). <br />Perennial species outnumbered annual species by eleven to eight. Both warm and cool season <br />grass species contributed to the cover, but warm season species outnumbered cool season species <br />by eight to four. <br />A total of eight species contributed more than 3% of relative cover (Table 4) including three <br />warm season perennial native grasses, one cool season annual introduced grass, one cool season <br />annual native grass, one annual introduced forb, and two annual native forbs. These species in <br />rank order (highest to lowest) include: sand dropseed, cheatgrass, sand bluestem, prickly lettuce, <br />prairie sandreed, Canadian horseweed, sixweeks fescue (Vulpia octoflora), and Cuman ragweed <br />(Ambrosia psilostachya). <br />Table 6: Reclamation Area 30 Species Composition <br />Life Form <br />Cover <br />Data <br />Present <br />Graminoids <br />Perennial <br />9 <br />11 <br />Annual <br />3 <br />3 <br />Native <br />11 <br />12 <br />Introduced <br />1 <br />2 <br />Cool Season <br />4 <br />6 <br />Warm Season <br />8 <br />8 <br />Total <br />12 <br />14 <br />Forbs <br />Perennial <br />2 <br />2 <br />Annual <br />5 <br />10 <br />Native <br />5 <br />8 <br />Introduced <br />2 <br />4 <br />Total <br />7 <br />12 <br />Woody Plants <br />0 <br />2 <br />Succulents & A avoids <br />0 <br />2 <br />Total Species <br />19 <br />30 <br />5.3 2014Revegetatlon Success Standards <br />Using the September 2013 through July 2014 precipitation (17.46 inches) in the predictive <br />equations presented in Section 3, the following standards were calculated for vegetation cover <br />and herbaceous production. <br />1.
