As one that visits Yellowstone annually, this is pretty much hokum. There are many other factors that contribute to whatever this not-so-educated person is claiming. I'd like to see the research.
Case in point, I could just as easily attribute the river change to the introduction of Lake Trout in Yellowstone Lake.
Lake Trout eat the native Cutthroat that don't travel up streams to spawn any more.
Bears that used to eat the Cutthroat got hungry and needed other food sources.
The Bears attacked the Elk Calves and bison calves in spring and began reducing the population of grazing animals.
The reduced population of grazing animals did allow the willows to grow.
This was repeated by a Park trained guide during one of our trips.
While the wolves have been good for the Park, attributing such complete credit for changes in the park is complete hokum.
I guess that's what happens when a Brit makes videos he knows nothing about.
By the way, the picture of the Badger was the European variety, not the North American variety, so it seems the video maker can't even get the species right. And personally, I haven't seen much new on the Beaver front in Yellowstone in the past 10 years. Just outside the park, headed towards Big Sky are some ponds that have been there for years.
If you want to see something that really changed the park, the policy to let fires burn was incredibly good. The 1988 fires cleaned the place of fuel, and amazingly, the burned areas now have incredibly thick groves of Lodge Pole Pine.
So, my conclusion about the video is that it's 5% real information 95% hokum.
