INTRODUCTION <br />Oxbow Mining, LLC is planning on continued surface disturbance activities that are <br />necessary as part of their underground mining operations. This includes exploration <br />drilling, Gob Vent Boreholes and access roads to these sites. In the past the process has <br />been to conduct surveys on an annual as needed basis. This has been time consuming <br />and at times probably not necessary. <br />In an effort to minimize surveys, in 2005 Oxbow contracted with Monarch & Associates <br />to have a large scale survey conducted. The area surveyed is shown on Figure I. The <br />purpose of these surveys was to delineate vegetation/habitat types and conduct surveys <br />for wildlife and plants listed as Threatened, Endangered and Sensitive Species (TESS) <br />and Management Indicator Species (MIS) as well as other species within those types. By <br />doing so, lazge expanses of certain vegetation types or azeas could be ruled out as areas <br />that would be used by listed species or in which listed species may be found. This will <br />help Oxbow and the agencies in long range planning for the azea. <br />There have been both office and field reviews of this proposed project for Threatened, <br />Endangered, Sensitive and Management Indicator Species that aze known to, or may <br />potentially be found in the area affected by this project. Wildlife and habitat surveys were <br />conducted for the project during the late spring of 2005. In addition to studies for this <br />specific site, habitat and wildlife studies have been conducted throughout the general azea <br />since 2002. This background data has been used to better evaluate the importance of this <br />azea for wildlife when compazed with other similaz habitat in the North Fork Valley. The <br />tables included with this report show federally listed Threatened or Endangered, USFS <br />and BLM Sensitive Species (TESS) and USFS Management Indicator Species (MIS) that <br />may potentially be found in the azea affected by this project or are listed by the GMUG as <br />occurring on forest lands. <br />EXECUTIVE SUMMARY <br />During the habitat and wildlife surveys conducted in May and June of 2005 no federally <br />listed Threatened or Endangered Species were observed in the project area. There is no <br />suitable habitat for Canada lynx, boreal toad or Uncompahgre fritillary butterfly. There <br />is no nesting or winter roost habitat for bald eagles within the project azea. Habitat is <br />lacking for the two listed plant species, Clay-loving buckwheat and Uinta Basin Hookless <br />Cactus. Habitat is lacking for the two listed candidate species, Gunnison sage grouse and <br />yellow-billed cuckoo. <br />Water withdrawal may affect species offish listed as endangered. However, the FWS in <br />two Biological Opinions has addressed this issue. Those opinions found that under <br />provisions of the Endangered Species Act, Oxbow Mining, LLC would not be in <br />violation if they limited water removal to the number of acre feet established by the FWS. <br />All Threatened and Endangered Species aze addressed in the Biological Assessment that <br />is part of this report. <br />
