We need a predator to control the deer population - I think. Hunting is not enough. But ditto about the uneasy feeling of being down the food chain...
How come no one worries about climbing in the Needles, Eldo, City of Rocks, Zion, Tuolumne, Smith, etc teeming with cats?
And the threat is over-sensationalized: 22 deaths in 120 years. We're so far down that food chain, it's about as likely as being taken out by a chunk of meteor.
Cougars won't control the deer population (nothing short of a massive cull will do that now), they'll move 'em around enough to release browsing pressure and get regeneration going again,http://www.eurekalert.org/pub_releases/2006-10/osu-cpk102406.phphttp://oregonstate.edu/ua/ncs/archives/2008/apr/loss-cougars-linked-disruption-yosemite-ecosystem
