MEMO KEITH KIRK, MIKE MCCARTHY DECEMBER 26, 1979 PAGE -2- 3) Table 33 - Those values given for vegetative cover do not agree with those values given for the specific range sites in table 36,37,39, and 40. Please clarify. The data for the other range sites (big sagebrush, treated sagebrush, and pastureland} should have a similar presentation as in tables 36,37, 35c. 4) Range site descriptions - The range sites should also include in the physiographic description the elavational range and the degree of slope. Included within the description the soils-vegetation relationships should be discussed. The acreage to be affected within each range site description should be presented in a table. 5) The nomenclature for t~e range sites should be consistent, the nomenclature varies from table (41)~table (42~.and maps 16 and 17.' b) Diversity -The application does not clearly address tlx: diversity question. The only information given is the number of species present. The applicant should use one of the published diversity indices or some other method to better explain the diversity of Species at the site. b) Section 780.18 1) The proposed seed mixture is comprised bf three Iifeforms: grasses, forbs and shrubs. The grass component of the mixture is comprised of 33.% introduced species. The number of introduced grasses should be reduced. The supporting argument for the use of introduced species based on land use is not directly applicable to this issue. Land use is based on management related activities, rather than the vegetation or cover of the land. The application rate should be translated into PLS thus giving the number of pure live seeds/ft2. Based on the seeding in- formation, the seeding rate is actually 153 seeds/ft which is significantly greater than that recommended by Cook. 2) The applicant should submit site specific data to demonstrate that cereal grains meet the mulching requirements of 816.14(c). Also, it is not certain if the wood chip mulch will be il~.d throughout the life of the operation In view of this a contigency mulching plan should be submitted. 3) The applicant should further discuss how seedbed preparation for the perennial species will be undertaken to minimize any negative impacts on volunteQr. shrubs. 4) The applicant should indicate what statistical measures were used to demonstrate that the reference areas are representative of the undisturbed sites. WWII Sudm~'~ a ~0~,~ Gi• ./1(,~ 5) It is not clear how the equation used to determine success of revegetation meets the requirements of this section. A further explanation of the equation and its application is required. 6) What method was used to determine the total vegetative biomass that will be used as mulch for the various range sites (cont'd)
