Future Research The Department is considering a graduate project to better quantify cougar distribution, abundance, and interactions with ungulate populations in Nevada. The departmental approach to this potential research is an “open-ended” study so that future studies in other parts of the State can contiguously tie into the ongoing effort. The primary objectives of the study will revolve around four areas of consideration. Those are: 1. Examine the genetic structure of cougars within Nevada and across state lines to identify distinct sub-populations and determine whether they interact as a “meta-population”. 2. Examine prey species selection and kill rates of radio-tagged cougars in select subpopulations. 3. Refine and validate the NDOW cougar population model through extensive ground truthing of model parameters and “spot checking” to test model accuracy. 4. Determine the relative influence of immigration (including source/sink dynamics), prey densities, habitat, roads, hunting pressure, human population growth and other potentially relevant factors in regulating cougar distribution and abundance in different areas of Nevada. The Nevada Department of Wildlife has been collecting DNA samples from harvested cougars for approximately four years and has over 500 samples. In 2002, the Department began the use of Matson laboratories to acquire more accurate lion age analysis. These age analyses are compared to age estimates provided by field personnel. Ironically, age in both sexes is generally overestimated with males being over aged at a higher rate than females, but the overall averages reveal the field personnel estimates are reasonably accurate (Lansford unpublished data). The teeth are extracted by the Department at the check-in on a volunteer basis but the practice is well supported by the sportsmen. In the past a letter authenticating the age the sportsmen’s harvested cougar was sent to them in appreciation for the sample. The practice is being resurrected. Conclusion As with all big game species in Nevada, cougar populations are carefully monitored for responses to harvest. The available data suggest the following: 1. Cougars in Nevada, while lower than peak numbers in the 1980’s, overall are well above historic levels. 2. Although deer populations and livestock numbers are declining range-wide across Nevada, other alternative prey species are increasing. It is important to understand how effective and efficient cougar populations are at prey switching. 3. The sex, age structure and harvest trends for different areas of the State are somewhat unique and dynamic and require management to reflect that in an adaptive strategy. 4. Research is needed to identify cougar dispersal patterns, corridors and relatedness through genetic structure. Proceedings of the Ninth Mountain Lion Workshop 59
