Northfield Permit Application <br />Preliminary Adequacy Review <br />Canada Lynx Lynx canadensis <br />Mexican Spotted Owl Strix occidentalis <br />This list is from: <br />http://mountain-prairie.fws. Qov/endspp/CountyLists/COLORADO.htm <br />November 9, 2006 <br />3 <br />T <br />T <br />The Colorado list of threatened/endangered species is found at: <br />http://wildlifestate.co.us/W ildlifeSpecies/SpeciesOfConcern/ThreatenedEndaneeredLisU <br />ListOfI'hreatenedAndEndaneeredSpecies.htm <br />The potential for impacts to plant and animal species that may occur, or have habitat, <br />neaz the mine site and that aze listed ands as threatened/endangered on the Federal and <br />State lists and as a candidate species on the Federal list must be evaluated in accordance <br />with Rule 2.05.6(2)(a)(iii) in the permit application. Each of the species listed for <br />Fremont County must be addressed. <br />Rule 4.15 - Revegetation <br />11. On page 2.05.4-10, NP has committed to vegetation monitoring in year 3 after reseeding. <br />Few details were provided describing the scope of the proposed monitoring. Generally, <br />for the year 3 monitoring, only cover data is collected using techniques similaz to what <br />was used for the baseline survey. Please provide additional detail regarding the <br />parameter(s) to be collected in year 3 and the techniques to be used. <br />12. NP states that Year 9 and 10 monitoring will be conducted in accordance with the <br />sampling methods and statistical demonstrations set forth in Rule 4.15.11. Rule 4.15.11 <br />offers several options. Please describe which sampling methods and statistical <br />demonstrations will be used. <br />13. In the monitoring paragraph on page 2.05.4-10, NP states that monitoring will be <br />conducted to evaluate revegetation trends and to determine necessary augmentation plans <br />such as interseeding. Please note that the approved husbandry practices are delineated in <br />Rule 4.15.7(5)(a)-(g). Augmented seeding is not allowed. Interseeding is allowed to <br />enhance species diversity if necessary based on the monitoring data. Interseeding is not <br />an allowable substitute for complete reseeding when vegetative cover is deficient. Please <br />remove or clazify the statement on augmentation and interseeding. <br />14. NP has presented a proposed seed mix on page 2.05.4-8 in Table 2.05.4-1. Intermediate <br />wheatgrass, an introduced grass species„' is the dominant seed. The Division recommends <br />that the Intermediate wheatgrass be replaced by a combination of native cool season <br />species such as: Junegrass, needle and thread grass, Sandberg bluegrass and thickspike <br />wheatgrass or slender wheatgrass. The NRCS also recommended (Exhibit F) that the <br />warm season species blue grama be included in the mix since blue grama is the primary <br />native species in the area. I would also suggest a couple other wane season grasses such <br />as: buffalograss, galleta grass and ring muhly. Please revise the seed mix at a minimum <br />
