Establishment of concentrated shrub seedling areas cost approximately 53000 to S50 D6 per • <br />acre (1991 dollars). Shrub seeding areas are less costly to establish, but their <br />effectiveness may not be as high without long-term suppression of competing herbaceous <br />vegetation during the critical first several years of shrub establishment end seailing <br />development. In addition, the attractiveness of reclaimed areas to big game species has <br />caused serious deprivation in many of the sites planted at regional mines. Live :;h rub <br />clump transplants ere far more costly end logistically more difficult to implement,. but <br />provide initial cover and habitat benefits with a potential for increased densities <br />(Agnew, personal communication, 1991). It will be more cost effective to implement a <br />concentrated shrub establishment program on fewer acres end improve limiting habitat <br />components such es water developments and establish additional habitat features such as <br />rock piles, perches, and nest boxes. These efforts yield positive and immediate results, <br />whereas the large scale shrub and tree reestablishment programs at the mines in northwest <br />Colorado have achieved varying but somewhat limited success (CMLRD-Coal Operators Meeting, <br />1992). <br />The reclaimed areas in the Yoast Mine area are irregularly shaped and not extensive. Much <br />of the reclaimed area outside of the haul road corridor is 1000 feet or less wide in . <br />disturbance. In the actual mining disturbance area, the widest point of total disturbance <br />is approximately 2800 feet wide with much of this area 2000 feet wide or less. The areas <br />of greatest width in disturbance are to receive the concentrated shrub establishment <br />areas. Extensive undisturbed woody vegetation surrounds all lends to be reclaimed and the <br />perimeter of the reclaimed areas will be irregularly shaped. The increase in edge end <br />regional habitat diversity provided by these reclaimed lends wi4l reduce the need for <br />extensive woody plant densities in the reclaimed landscape. <br />A shrub density standard is not proposed for the haul road corridor for the following <br />reasons. The maximum width o1 the disturbance area is approximately 200 feet, <br />representing a minimal disturbance in relation to the surrounding area. Also, the <br />extensive shrub stands which dominate the area will be complimented by the addition of <br />areas with succulent herbaceous forage. Both livestock end wildlife will be benefited <br />from this greeter diversity of habitat. <br />Seasonal Yeriety. Revegetation success for seasonal variety in the reclaimed areas will <br />not be evaluated since nearly all the species in the premining vegetation types are cool • <br />season species. The seed mixes have been developed to establish the species best adapted <br />48 <br />
