Oregon’s Proposed 2016 Big Game Regulations (Cougars)

Below are the comments I sent to the Oregon Fish and Wildlife Commission regarding the 2016 Big Game Regulations they are considering at a meeting on October 9th, in Florence, Oregon.

Re: 2016 Big Game Regulations

Dear Chairman Finley and Commissioners,

Please reject the four proposed “target areas” for cougar in the 2016 Big Game Regulations.

In these target areas, ODFW has an objective of killing 95 cougars at a cost of nearly $70,000, purportedly, for the benefit of deer and bighorn sheep, and to reduce conflicts with humans. This proposal is incompatible with scientific findings and will not accomplish the intended goals.

This proposal takes its cue from the outdated 2006 Cougar Management Plan (ODFWa). Under that plan’s “adaptive management” approach, cougars can be targeted in areas with low or declining ungulate populations. A truly adaptive management plan, however, would incorporate the latest scientific findings. Scientists have found that killing cougars to increase deer populations doesn’t work. Cougars often kill deer that are weak, sick, or generally in poor condition, deer that would have otherwise died due to environmental circumstances (Bishop et al. 2009; Hurley et al. 2011; Forrester and Wittmer 2013). Changes in deer populations are more likely linked to habitat and environmental conditions (Monteith et al. 2014).

In fact, ODFW already experimented with killing cougars to boost deer populations from 2010 to 2014, and it didn’t work. Under the Oregon Mule Deer Initiative, ODFW killed cougars in two of the same target areas identified in the proposed 2016 Big Game Regulations (Steen Mountain and Warner). From 2010 to 2014, 112 cougars were killed in these target areas. Using a “comprehensive method of counting and modeling deer populations” ODFW was not “able to document a significant change in population” (ODFWb, p. 41).

According to peer-reviewed scientific findings and ODFW’s previous attempts, killing cougars to boost deer populations does not work. The Commission should abandon the killing of cougars in target areas to boost ungulate populations and refocus resources on proven measures that actually benefit ungulates.

Please reject the four proposed target areas for cougar in the 2016 Big Game Regulations.
