The site is located just west of Greeley, <br />along the Cache La Poudre River. The location is shown on the attached U.S.G.S. <br />topographic map and described in detail on the U. S. Fish and Wildlife Service <br />(USFWS) Survey Field Uata Compilation Form included at the end of this report. <br />Photographs of the site are also provided. <br />The Preble's jumping mouse is currently classified by the USFWS as <br />threatened and is protected under the Endangered Species Act of 1973, as amended <br />(16 U.S.C. 1531 et. se .. Field studies described herein were performed in <br />accordance with the USFWS Interim Survey Guidelines for the Preble's Meadow <br />Jumping Mouse, revised May 19, 1999. Wildlife collections were performed under <br />Federal Fish and Wildlife permit number PRT-704930, and State of Colorado permit <br />number 99-TR541. <br />MF,TIIODS <br />As mentioned above, the methods used in this study follow current 1JSFWS <br />guidelines. Additional details regarding schedule and procedures pertinent to this <br />study are as follows: The trapping effort consisted of a 750 trapnight effort, with <br />traps checked over five days (30-31 July and 1-3 August 1999). All animals that <br />were captured during the course of these investigations were identified in the field <br />and immediately released. All traps were placed in willow shrub habitat along the <br />banks of the river. <br />RESULTS AND DISCUSSION <br />No Preble's jumping mice were captured at the Riverview Resource Property <br />site. While potential habitat is present on the site, this location is approximately 30 <br />tniles east of the Front range and a long distance from Preble's jumping mouse <br />capture locations. <br />O[her species of small mammals that were captured during these <br />investigations are as follows (number captured in parentheses): deer mice, <br />Pervmyscu.c maniculcerus (85), voles (Microtus nchrogaster and M. pennsylvnnicus <br />(17), and house mice, Mus musculus (11). <br />The attached USFWS Survey f field Data Compilation Form has been <br />completed and should he consulted for a summary of results and a detailed site <br />description. <br />2 <br />
