Peter Paage <br />Parker/Dersham Resource Site -Mouse Disqualification Request <br />Page 2 <br />s <br />Based_on a field investigation conducted by Savage and Savage on May 26, 2005 and- <br />current U.S. Fish and Wildlife Service (USFWS) interim survey guidelines dated April' <br />27, 2004, we believe this site is exempt from the necessity to conduct Preble's trapping <br />and has very low potential to harbor individuals or a population of Zapus hudsonius <br />preblei for the following reasons. <br />Characteristic Preble's habitat is not .located within the Pazker/Dersham Resource site. <br />The proposed site is dominated by ruderal species that include whitetop (Cardona <br />draba}, Canada thistle (Cirsium arvense), and- curly dock (Rumex crispus). No water <br />feattires or wetlands were observed on the site, <br />Hall-Irwin's Baseline Resource, an ongoing mineral extraction site, is located between <br />the proposed Pazker/Dersham Resource site and the South Platte River. The Baseline <br />Resource site isolates the proposed mineral extraction site from the South Platte River <br />due to ongoing mineral extraction and overburden and resource material.stogkpiles that <br />aze located along the east edge of the proposed site. <br />Preble's meadow jumping mouse habitat is not found on the proposed site due to a tack. <br />of wetlands or an accessible waterway, ruderal plant species with no shrub or other <br />overstory, and ongoing mineral extraction that isolates the proposed site from the South <br />Platte River: A Preble's meadow jumping mouse survey was conducted immediately <br />north of the proposed site, and no mice were encountered. <br />For the above reasons we request a concurrence for disqualification ofthis site for further <br />consideration as Prelile's habitat and exclude the site from the trapping requirements. If <br />you have any questions, or we can provide additional supporting information regazduig <br />this concurrence-request for disqualification fog-the Zapus hudsonius preblei on the <br />Pazker/Dersham site; please contact us. <br />Sincerely; , <br />Edith Savage <br />Principal <br />c: Jeff Gregg, Hall-Irwin Corporation <br />Karen Flanders, Civil Resources <br />attachments: General Location Map <br />Site Photos <br />
