5. REVEGETATION MONITORING <br />• Requirement <br />Rule 4.15.1(4) of the Colowyo Permit contains a plan for monitoring the success of revegetation. <br />Response <br />During the summer of 1995, Colowyo completed vegetation monitoring on the following azeas: <br />A.. Herbaceous Frequency and Density of the 1994 Revegetated Area <br />B. Herbaceous Cover of the 1978, 1984, 1987, 1990 and 1993 Revegetated Areas <br />Refer to Exhibit 10. 1995 Annual Report Map, for additional details as to the location of these <br />azeas. <br />C. 1995 Comprehensive Woody Plant Data. <br />A. HERBACEOUS FREQUENCY AND DENSITY OF THE 1994 REVEGETATED AREA <br />The area seeded in the fall of 1994 was undergoing the first growing season. Past sampling <br />methodologies continue to be used to obtain vegetation data. Two hundred fifty (250) placements of <br />a 60 crn X 60 cm frame was used and species occurrence was recorded. <br />The data has been s»n+mariZed and the top 20 species by occurrence is presented in Exhibit 5 <br />Reve¢etation Monitoring. The data indicates a reasonably diverse, successful establishment of desirable <br />perennial grasses and forbs, as well as the expected number of annual grasses and forbs. <br />B. HERBACEOUS COVER OF THE 1978. 1984. 1987. ] 990 and 1993 RECLAIMED AREAS <br />During the summer of 1995, the 1978, 1984, 1987. 1990 and 1993 reclaimed areas were <br />sampled for herbaceous cover to monitor the initial success of the revegetation efforts. <br />Exhibit 5, Revegetation Monitoring, contains the results of this sampling. The data indicates <br />an initial estabhshment ofherbaceous species mceting or exceeding our expectations for the reclamation <br />plan and the requirements of the postmining land use. <br />Please note that we sepazated the data by reclamation year for the purpose of monitoring <br />interest. Monitoring for bond release would not separate the reclamation by year, rather all areas would <br />be lumped together and randomly sampled. <br />U <br />
