Dan Mathews Aoril 4, 2007 <br />selected species/components within stands where the components are poorly <br />represented may be necessary to meet bond release standards. We would <br />encourage SCC to consider submittal of a future revision application to address <br />these concerns, although it may be prudent allow for a period of time to assess <br />the initial results of the North Decline cheatgrass suppression/interseeding <br />project, before pursuing further "husbandry" or "remedial" treatments. We would <br />note that two of the cool season grasses (crested wheatgrass and Russian <br />wildrye) and one of the subshrubs (prostrate kochia) are non-native species, and <br />as such, use of these species would likely reinitiate the full 10 year liability <br />period. The inclination to avoid introduced species so as not to reinitiate the full <br />10 year liability period, should be weighed against the ability of alternative native <br />species to establish and persist in the presence of cheatgrass competition, as <br />effectively as the introduced species. Please give consideration to these <br />issues and provide a written response. <br />SCC: The following is the comment Snowcap received from Cedar Creek <br />Associates. <br />"In the interest of not resetting the 10-year liability period, and following review of <br />the options provided, the recommended species for the "interseeding" seed mix <br />has been amended to include only native species. It is likely that there will be <br />future modifications of the species in the mix and seeding rates as the North <br />Decline cheatgrass suppression project is analyzed. <br />S ecies <br />Warm-season Grasses <br />Galleta Pleuraphis jamesii <br />Curly Mesquite Hilaria belangeri <br />Big Galleta Pleuraphisrigida <br />Cool-season Grasses <br />SVeambank wheatgrass Elymus lanceolatus ssp.psamm. <br />Thickspike wheatgrass Elymus lanceolatus ssp. 1. <br />Bluebunch wheatgrass Pseudoroegneria spicata ssp. s. <br />Perennial Forbs &subshrubs <br />Palmer penstemon Penstemon Palmeri <br />Prairie sage Artemisia ludoviciana <br />Sulfur Buckwheat Eriogonum umbellatum <br />Desert Globemallow Sphaeralcea ambigua <br />Gardner saltbush Atriplex gardneri <br />Winterfat Krascheninnikovia Janata <br />Please let us know if you have any questions or comments. <br />Sincerely, <br />o,- <br />on Hammond <br />Owner's Representative <br />Lbs/acre Seeds/FtZ <br />2.0 7.30 <br />1.0 6.20 <br />1.0 8.03 <br />1.0 3.20 <br />2.0 7.07 <br />1.0 3.20 <br />0.5 7.00 <br />0.25 26.0 <br />0.5 2.40 <br />0.5 5.70 <br />1.0 2.56 <br />2.0 2.60 <br />12.75 81.26 <br />cc: DRMS Denver Office <br />
