The column that is bolded shows the pounds Pure Live Seed for each <br />species that is needed to be applied for each acre. <br />The seed will be accompanied by an official seed analysis report that provides documentation to <br />show no noxious weed seed per Colorado State weed law and no more than 0.5% other weed <br />seed. The seed documents will be one of the following, a certified Blue Tag, an independent <br />seed lab test, or a seed lab analysis supplied by the vendor. <br />Weed surveys were conducted in October 2008 and May 2009 as described in Appendix F - <br />Plants and Wildlife and shown on Map I-1 - Soils and Noxious Weeds. Best management <br />practices will be observed to minimize the occurrence and spread of noxious weeds including: <br />Weed surveys will be made of the permit area each spring <br />If noxious weeds are identified, they will be sprayed with methods and chemicals <br />approved by the weed control staff of Montrose County and the BLM. <br />After reclamation, weed surveys and spraying will continue until the perennial cover and <br />production of the site have met State requirements and the bond release has been <br />obtained. <br />Re-vegetation Success Criteria. The pre-mine site is a highly disturbed area dominated by <br />pinyon/juniper/sage species with undergrowth of grasses and forbs. As seen in the aerial <br />photographic base maps and on numerous photographs taken in the area, at least 40% of the <br />ground is barren rock or established roads and trails. Based upon this reconnaissance of the area <br />it is recommended that the post-mining vegetation standard include more grasses, forbs and <br />shrubs with a similar 40% cover. <br />Last Chance Mine - April 2009 E-4
