<br />~, <br />Section 780.18 (b) Continued. <br />Revised 11(20/80 <br />their work at the Kemmerer Mine in southwestern Wyoming which is <br />located in a similar vegetation type and receives approximately the <br />same precipitation as the Marr Mine, Howard and Samuel (1979) <br />reported that 1,457 shrub seedlings per acre could be expected to <br />volunteer from topsoil alone. Shrub seed established via direct <br />seeding in revegetation research at the Piceance Basin, in north- <br />western Colorado, using a mixture with various forbs and grasses <br />yielded shrub density figures of 48,580 per acre when shrubs were <br />planted in a combination mixture of native and introduced grass <br />species in a 30.5 cm cover of topsoil (Colorado State University, <br />1979). These studies both indicate that shrubs rapidly become <br />established on both respread topsoil and from planted seed. The <br />immediate reapplication of topsoil and heavy seeeding rate for <br />shrubs should hasten the reestablishment of shrubs at the Kerr Mine <br />Area. <br />As requested by Kevin Allred of OSM, Kerr Coal has xeroxed the <br />section on shrub reestablishment relative to Northwest Colorado. <br />This section of the Piceance Basin study reported by Colorado State <br />University, 1979 has been included as Exhibit 57, Rehabilitation <br />Potential S Practices of Colorado Oil Shale Lands. <br />780-77 bb <br />
