However, the CMLRD felt that Trapper should <br />provide a shrub clump standard as well as a shrub density standard between <br />mature shrub clumps. Gregg, you suggested we propose a standard within shrub <br />clumps based upon our historic success. <br />Therefore, based on Table 1 (originally submitted as part of correspondence <br />dated December 17, 1986), Trapper proposes a minimum mature shrub clump den- <br />sity standard of > 3,764 shrub stems per mature shrub clump (90 Y, of the mean <br />with 90G statistical confidence). The mature shrub count will be based on the <br />species listed in Table 2. <br />For between mature shrub clumps, the DOW recommends a level of shrubs be <br />reestablished sufficient as winter range (Dec 15 - Mar 15) to support an elk <br />herd of some size. Trapper proposes that the standard be such that the carry- <br />ing capacity of the site reflecting historic useage is maintained. The entire <br />survey area (both areas to be disturbed, presently disturbed, and not dis- <br />turbed by mining activities) should be considered in determining whether that <br />historic useage is maintained. <br />All the parties participating in the above meeting anticipate that the shrubs <br />will continue to mature after bond release and produce even more winter forage <br />than the standard contemplates, even though this factor cannot be used to set <br />the standard. <br />Using the above recommendations, Trapper calculated that out of 23,075 acres <br />of available winter range over the survey area, and given a historic winter <br />elk use of 256.2 animals, 184.6 acres of shrubs are needed to support historic <br />winter use by elk. This value was inflated 1006 as a safety factor giving <br />cont. <br />P.0. Box 187 Craig, Colorado 81626 (303) 824-4401 <br />
