RULE 4 PERFORMANCE STANDARDS <br />During the second and fourth growing season of a reseeded area, herbaceous cover and <br />woody plant density information will be gathered. This information will be gathered at the <br />species level and will reflect the effectiveness of the seed mixture and volunteer species. <br />Colowyo will also monitor areas seven years old and every third year thereafter (year 10, <br />13, etc.) to assess their status toward approaching the maturity necessary for bond release <br />testing. Seven year and older monitoring will also utilize ground cover and density <br />sampling, but will include a modest current annual production sampling effort to facilitate <br />evaluation of progress toward meeting this variable and to allow a determination of <br />carrying capacity should a program of livestock grazing be implemented. After 7 years of <br />growth and where practicality dictates, revegetation units may be combined into logical <br />management units for sampling / monitoring purposes, rather than remaining autonomous. <br />Monitoring will cease following Phase III bond release. <br />4. The data and an assessment of the monitoring results will be submitted in the Annual <br />Reclamation Report. A map will be included to delineate the reclaimed areas being <br />sampled each year. The Annual Reclamation Report will also provide details regarding <br />restricted interseeding or other mitigative measures implemented as a result of the <br />vegetative monitoring program. <br />4.15.2 Use of Introduced Species <br />For pre -2008 revegetation, (especially pre -2002 revegetation) an examination of the seed mixture <br />approved for the reclamation of rangeland indicates that Colowyo included some introduced <br />species in the mixture for which regulatory approval was obtained. Introduced species included <br />in the seed mixture were: <br />(1) Intermediate Wheatgrass (Agropyron intermedium) <br />(2) Siberian Wheatgrass (Agropyron sibericum) <br />(3) Pubescent Wheatgrass (Agropyron trichophorum) <br />(4) Smooth Brome (Bromus inermus) <br />(5) Orchard Grass (Dactylus glomerata) <br />(6) Vinall Russian Wildrye (Elymus junceus) <br />(7) Durar Hard Fescue (Festuca ovina duriscula) (Actually Native) <br />(8) Timothy (Phleum pratense) <br />(9) Kentucky Bluegrass (Poa pratensis) (Naturalized Taxon) <br />(10) Lutana Cicer Milkvetch (Astragalus cicer) <br />(11) Blue Flax (Linum lewisii) (Actually Native) <br />(12) Alfalfa (Medicago sativa) <br />Of the 31 species approved, 21 species are native. On a seed weight basis, 65% of the seeds to be <br />planted are native species seed. <br />The introduced species were included in the mixture because they were thought to be necessary to <br />control erosion and because they provide forage for wildlife and livestock on the reclaimed area. <br />The research at Colowyo by the Colorado State University (CSU) Agronomy Department has <br />documented the superiority of the introduced species for revegetation purposes compared with <br />Rule 4 Performance Standards 4-47 Revision Date: 5/25/18 <br />Revision No.: RN -07 <br />
