RULE 4 PERFORMANCE STANDARDS <br /> within each quadrat. Conversion to the number of emergents per square foot facilitates an <br /> assessment of the eventual success of the seeding effort. <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 /> Rule 4 Performance Standards 4-39 Revision Date: 12/20/19 <br /> Revision No.: TR-135 <br />
