Post underground and current surface mining operations have had <br />little negative effect on cliff nesting success especially for the <br />Golden Eagle. <br />During the 1996 Permit renewal process the Division requested an <br />up-to-date consideration of the latest (August 21, 1496) USF'WS list <br />of federal threatened and endangered wildlife species. In <br />particular, the Southwestern willow flycatcher, the Mexican spotted <br />owl, the Mountain plover and the Boreal toad appeared as recently <br />listed T&E species_ Subsequent discussions with local BLM officials <br />confirmed that these species would not occur on the Colowyo area. <br />A copy of the BLM correspondence can be found in Exhibit 10 - <br />Vegetation Information. <br />Tmgact of Mining Og ra 'onG on Wildlif R ou Within th Permit <br />Area <br />Initial wildlife studies beginning in 1974, indicated that prior to <br />mining the following conclusions could be made: (1) some browse <br />~ species continually receive more use than others; (2) use of browse <br />is both a function of desirability and availability; (3) the <br />general condition of the browse remains poor overall but is <br />steadily being improved by range management practices; (4) carrying <br />capacity is also below the potential for the site, but is steadily <br />increasing as habitat improvement areas accumulate; (5) poor range <br />management practices have occurred in the past; and (6) the study <br />. area is utilized on a year-around basis, depending on snow depth <br />with highest use during spring and fall. <br />i Before the startup of mining operations at Colowyo, the potential <br />wildlife impacts predicted in environmental work included the <br />displacement of wildlife from large areas around mine sites; <br />disruption of migration routes; disruption of calving and fawning <br />area with untold negative impacts on populations, habitats lost for <br />long periods of time, etc. <br />Observations at Colowyo, and at several other mines in northwest <br />Colorado over the last five years, have shown that many of these <br />potential impacts have not materialized. It has become very <br />evident that wildlife are a lot more adaptable than previously <br />predicted in baseline studies.
