This report details the results of a small mammal survey targeting Preble’s meadow jumping mouse (Zapus hudsonius preblei; hereafter Preble’s) and performed between 11 August and 19 August 2008, along Crow Creek on F.E. Warren Air Force Base (hereafter FEWAFB) near Cheyenne, Wyoming. This is the eleventh such survey performed by the Wyoming Natural Diversity Database (WYNDD; University of Wyoming) at this site (see Garber 1995, Beauvais 1998, Keinath 2001, Dark-Smiley and Keinath 2002, Beauvais 2003a, Beauvais and Gruver 2004, Beauvais and Smith 2005a and 2005b, Beauvais and Keinath 2007, Beauvais and Griscom 2008). These reports, in addition to Elliot (1996), Schuerman and Pague (1997), Travsky (1997), and Young et al. (2000) represent thirteen consecutive years of Preble’s survey and research on FEWAFB.
