I took part in a lion study for the state of Oregon a few years back. The southern Oregon biologists that we worked with would openly admit cougar studies are flawed. There is very little known about them, I have treeed two mature tom's and a female of the same kill. Hmm, according to the bugs (biologists) that would never happen. I have spent the majority of my life running these animals. I have a great respect for these animals as I have seen more than most people will in ten lifetimes.
The state's normaly under estimate the populations by approx. 20-30 percent, according to the Oregon biologists. I spend a lot of time in the woods, hunting and keeping my dogs in shape. I spend on average 10-12 days a month in Oregon running my dogs. When the snow fly's we see a lot of lion tracks and we would have no problem running two a day. The population is not declining, we just need some current studies. When the bounty was still on them the hound hunter's would go weeks before they cut a track to run. The population has been on the increse since then.
