Synopsis:
Beginning in 2010, we conducted a pilot study of mountain lions in Marin County using motion-triggered cameras. Our objectives were to obtain additional documentations, confirm the presence of mountain lions outside of Point Reyes National Seashore, and  determine if mountain lions had a regular presence in the county. We deployed a total of 14 digital cameras: three Cuddeback Capture (Cuddback Digital, De Pere, WI) incandescent flash cameras taking still pictures and 11 Bushnell Trophy Cam IR (Alliant Techsystems Inc., Anoka, MN) cameras set in video mode. We set unbaited cameras within four focal areas on private and public lands, with successive starting dates for the four areas as access permission was obtained from land owners or management agencies for monitoring: (1) Nicasio—01 October 2010; (2) Olema—21 January 2011; (3) the Alpine Lake region of Mount Tamalpais—26 September 2011; and (4) Bolinas—12 September 2012 (Figure 1; geographic center: 38º 00’ N, 122º 41’ W).
