Section 816.112 (d) Continued. Rule 2.05.4 (2)(e) <br />Revised 11/4/80 <br />u <br />Intermediate wheatgrass and Russian wildrye are also reported to be <br />highly more successful than almost all native species. Indeed, a <br />field planting guide for northwest Colorado prepared by the United <br />States Department of Agriculture Soil Conservation Service (SCS) <br />in 1977 stated that in the area of the Kerr Mine and the Kerr <br />Tipple, the recommended introduced species include: crested, <br />intermediate and pubescent wheatgrass, Kentucky blue grass, and <br />timothy. Lang, et al. (1975) stated that for areas with less than <br />9 inches of precipitation, such as those found 1n North Park, <br />desert and tall wheatgrasses were highly recommended for seeding on <br />mining disturbances. Hassell (1979) reported that of three dryland <br />plantings made in North Park the species most successful in provid- <br />ing early groundcover was pubescent wheatgrass followed by crested <br />wheatgrass. Plantings made by Kerr Coal in 1975 evaluated some <br />eight species of which crested wheatgrass and yellow sweetclover <br />were the most successful species. The most outstanding Species <br />planted at the idyoming Fuels Sigma Mine in 1978 was Russian wild- <br />rye.~ Plantings made at the Marr Mine in 1979 by the SCS indicate <br />that the most outstanding species planted was pubescent wheatgrass. <br />Tall wheatgrass species planted was pubescent wheatgrass. Tall <br />wheatgrass has been included in the mixture since it has been <br />widely planted at the Arapaho National Wildlife Refuge for nesting <br />cover for birds and due to its ability to trap blowing snow. <br />Necessity of Introduced Species to Aid Erosion Control. The above- <br />cited reports and on-site results conclude, without exception, that <br />the most immediate and effective stabilization for reseeded plants <br />is produced by introduced species. Moreover, because they are <br />better able to establish themselves under adverse conditions, the <br />~~ <br />proposed introduced species are needed to control erosion by pro- <br />viding rapid growth and a more dependable early plant cover than <br />the slower developing native species. 2n addition, as documented <br />in the above-referenced reports, unlike some of the recommended <br />816-147 a <br />
