When they "reintroduced" them into the Yellowstone eco system, the elk population fluctuated between 17,000 to 20,000 yearly with several thousand cow permits given out each year. Less than 20 years later, elk numbers are down to less than 1,000 with no cow permits available. I have reintroduced in quotes because what they brought in was not the Grey wolf that hunted mostly small game with an occasional deer thrown in and weighed maybe 80 pounds but the Canadian Timberwolf which can weigh over 200 pounds and is a killing machine. Where I live in nw Montana, with 2 large wolf packs roaming, the elk harvest has been falling every year for the last 7 years. I used to think that it was done by some misguided libtards who wanted to be able to see and photograph wolves in the wild. Lately, I've had an epiphany. I now believe that it was done as part of a larger plan to control our food supply.
