Source-Sink Dynamics and the Recovery of Overexploited Cougar Populations David C. Stoner, Department of Wildland Resources, Utah State University, Logan, UT 84322-5230, USA, david.stoner@usu.edu Michael L. Wolfe, Department of Wildland Resources, Utah State University, Logan, UT 84322-5230, USA, michael.wolfe@usu.edu. ABSTRACT The cougar (Puma concolor) is a large New World felid that has demonstrated remarkable resilience to anthropogenic impacts, remaining one of the most prevalent large carnivores in North American ecosystems. Presently, cougars are subjected to annual harvests over much of their current range, yet the impacts of sustained hunting on demographic structure and population persistence are not well understood. We have been monitoring two cougar populations in Utah, USA, since 1997. We compared demographic characteristics between an exploited and a protected population to examine the behavioral mechanisms of population recovery and productivity. The treatment population had a younger age distribution, low survival, declining density, and variable fecundity, and generally fit the profile of a sink population. In contrast, the reference population exhibited the opposite trends in nearly every parameter and appeared to act as a source. Under these conditions, sustained exploitation created an ecological trap on the treatment site. Data five years posttreatment suggests that following the implementation of a constant number of permits, the sink population recovered in phases and began functioning as a source. We offer empirical evidence for the occurrence of source-sink dynamics in an exploited cougar population, and argue that in conjunction with the principles of landscape ecology, the source-sink model of population regulation holds promise for the conservation of exploited cougar populations.

Censusing Pumas by Categorizing Physical Evidence Roy T. McBride, Livestock Protection Company, 26690 Pine Oaks Road, Ochopee, FL 34141, roy@livestockprotection.net Rocky T.

Box 455, Alpine, TX 79831, cougarmc@hotmail.com ABSTRACT The occurrence of Puma concolor can be confirmed by detecting physical evidence (i.e. tracks, urine markers). However, determining the number of pumas responsible for creating this sign is problematic. We addressed this difficulty by categorizing physical evidence (sign) and tested our method during the Puma concolor coryi (Florida panther) project. Three rules were used to distinguish individuals. (1) gender was determined by track size or stride length; (2) time (freshness) was determined by known events within the past 24 hours such as wind or rain; (3) distance between individual track sets was used as an exclusionary tool to avoid overcounting. We verified accuracy by capture and comparison to 3 other indices. This method could be adapted to census other large felines. Proceedings of the Ninth Mountain Lion Workshop 185
