There's something to what he says.
A herd that big can cause tremendous stress on the grazing and migration areas.
Used to be when the heavy snows hit Yellowstone Park 20,000 elk would come pouring out, through fences, ranches, across roads, looking for forage.
But then they would fan out and settle and most everything was good. Twenty thousand was too big a herd. Two thousand is a tragic joke.
They could have trimmed the herd by increased hunting. Instead they wanted to play God, and brought in the wolves, as least as much out of loathing for the people on the land as for elk management.
The Feds and local game authorities have been lying and dumbing-down now for thirty years.
Their latest stupidity showed up just a month or so ago. They were talking about an onset of chronic wasting disease, which can lethally afflict elk, deer and other big game.
At the meeting it was decided that the best method would just be to let the wolves sort it out. The main guy said, "Well, the wolves eat the elk, and the best part is that it's free!" (Which it is not, of course---millions upon millions are poured into "managing" the wolves.)
So the Montana Fish Wildlife & Parks' solution to a disease risk is to let the predators kill them all before they can get sick. Sheesh...
Bingo! Both Yellowstone and Teton Nat. Parks are surrounded by Nat. Forest lands where hunting is permitted. If they would issue adequate permits.
What the biologists seem to me to be missing is that prey animals have been significantly reduced in number and in range by modern society. That is not going to change. When North America was open from the Arctic to the Gulf of Mexico and from the Atlantic to the Pacific it wasn't possible for predators to decimate populations of prey animals. It is possible now because the ranges that elk have today are far smaller and consist primarily of the harshest zones of their historical ranges. High altitudes IOWs.
