All numerical data were entered in spreadsheets with Microsoft Excel 5.0 (Microsoft
Corporation, Redmond, Washington, 1994). Statistical analyses were performed with
Microsoft Excel 5.0 or StatMost for Windows (DataMost Corporation, Salt Lake City,
Utah, 1995). Qualitative data were entered in a database in Q&A for Windows
(Symantec Corporation, Cupertino, CA, 1993).
Authorship and Acknowledgments.—Data were compiled and the report was drafted by
David M. Armstrong; any questions about the report or technical aspects of the work
should be directed to him. Clint Miller and Michael Sanders provided logistic support,
assured access, and helped to prioritize sites (so that their immediate needs for
information to inform management decisions were met). They also reviewed and
contributed to drafts of this report. Martin Margulies directed the field crew, which
included at various times Schuyler Greenleaf, Jasmin Becker, and Cary Richardson.
Special recognition is due to Mark Gershman, Tamara Nauman, John Osborn, and
Mandy Smith for their contributions to the study. Also, we thank a number of volunteers,
including Avery Colfelt and several students from "Mammalogy" (EPOB 4760/5760),
University of Colorado-Boulder.
Research from May to mid-September was supported by a grant from the United States
Fish & Wildlife Service (USF&WS), with matching funds from the City of Boulder Open
Space and Real Estate Department and the Boulder County Parks and Open Space
Department. Research after 15 September was funded by the City of Boulder Open
Space and Real Estate Department.
RESULTS AND DISCUSSION
Small Mammals
General Results.—General results of livetrapping prior to 15 September are presented
in Appendix I. Numbers presented do not include recaptures. Overall, 1429 individuals
of 11 species were captured on the 15 sites over 17,800 trapnights, a capture rate of
8.0%. Mean number of captures per week was 95.3. On no grid or individual transect
were traps ever more than 50% full, so our presumption was that availability of traps
was not a factor limiting rates of capture.
Meadow jumping mice were captured on only two sites, 14 on the VanVleet Parcel (10
in June and four in September), and nine on the adjacent Gebhard Parcel. No meadow
jumping mice were taken on the other study sites, even those from which the animals
have been reported previously (Sawhill Pond, Tracy Collins, Hedgecock-Neuhauser,
Lindsey). On the VanVleet Parcel, meadow jumping mice were captured on transects A,
B, C, and F in May and on transects D and F in September. On the Gebhard Parcel, Z.
hudsonius was captured on transects A, B, and E.
In addition to captures of meadow jumping mice in the course of the present project,
