Further, you have proposed that a minimum of 20% of the reclaimed slopes less than 5:1 would be Designated shrub clump establishment areas where transp~anting of mature shrub clumps and/or direct seeding and transplanting of shrub seedlings would be employed. Messures to enhance establishment of seedling shrubs in the shrub clump establishment areas will include the use of direct haul topsoil and/or a moaification of the regular herbaceous seed mix (so as to reduce the competition between herbaceous species and seedling shrubs). -he Division has two remaining concerns. First, as you have observed, a standard of 1,000 woody stems per acre has been recommended by the Division of Wildlife for reclaimed lands in Northwest Colorado. Given the somewhat generalized nature of the shrub establishment plan provided by Colowyo and the lack of specific justification for the propose: 850 stem per acre stem density • standard, the Division does not feel comfortable in approving a woody density standard which is lower than that recommended by the Division of Wildlife. Second, the plan indicates t:~at in some instances the regular seedmix will not be seeded in order to reduce herbaceous competition. The Division agrees that an alternative seed mix is warranted. Information should be submitted on the modified seed mix and seeding rate and the criteria which will be applied in selecting areas which would not be seeded with the regular seed mix (acreage, slope, erosion control etc.). In resolution of Stipulation No. 5, the Division sets the woody plant density standard for the Colowyo Mine at 1000 stems per acre for all portions of the reclaimed area except perimeter slopes which are steeper than 5:1. Shrub reestablishment is to be accomplished as specified in this letter and your tatters of November 8, 1983 and October 25, 1984 (with the exception being the objective of 1000 stems per acre rather titan 850 stems per acre).
