5. REVEGETATION MONITORING <br />• Requirement <br />Section 4.15.1(4) of the Colowyo Permit contains a plan for monitoring the success of revegetation. <br />Response <br />During the summer of 1997, Colowyo completed vegetation monitoring on the following areas <br />A. Herbaceous Frequency and Density of the 199b Revegetated areas in the East, West and <br />Section 16 pits <br />B. Herbaceous Cover of the 1980, 1983, 1986, 1989, 1992 and 1995 Revegetated Areas <br />Refer to Exhibit 10 1997 Annual Report MaR, for additional details as to the location ofthese <br />areas. <br />C. 1997 Comprehensive Woody Plant Data for the establishment areas.. <br />A. HERBACEOUS FREQUENCY AND DENSITY OF THE 1996 REVEGETATED AREA <br />The areas seeded in the fall of 1996 and early spring of 1997 were undergoing the first growing <br />season. Past sampling methodologies continue to be used to obtain vegetation data. Two hundred <br />• fifty (250) placements of a 60 cm X 60 cm frame was placed randomly throughout the reclaimed areas <br />and species occurrence was recorded. The EasUWest Pit data were combined separately from the <br />Section 16 Pit data. <br />The data has been summarized and the top 20 species by occurrence is presented in E i it 5 <br />Revegetation Monitoring. The data indicates a reasonably diverse, successful initial establishment of <br />desirable perennial grasses and forbs, as well as the expected number of annual grasses and forbs. <br />B. HERBACEOUS COVER OF THE 1980. 1983. 198b. 1989. 1992 and 1995 RECLAIMED <br />AREAS <br />During the summer of 1997, the 1980, 1983, 1986, 1989, 1992 and 1995 reclaimed areas were <br />sampled for herbaceous cover to monitor the success of the revegetation efforts. <br />Exhibit S, Revegetation Monitoring, contains the results of this sampling. The data indicates an initial <br />• 12 <br />
