Hi, it’s Harry Silhouetteof-Wolfhowlingonhill, television correspondent at the Greenygrey. I was delighted to see that the BBC‘s fascinating series, Nature’s Microworlds, recently had an episode about how wolves reintroduced to Yellowstone in the 1990s helped the oldest national park in the world’s river ecosystem return to its best state since wolves were exterminated in the 1920s.
Yellowstone Wolves Benefit Beavers and Biodiversity
In Nature’s Microworlds‘ infotainment style, the Steve Backshall-narrated documentary took the viewer through several reasons why wolves might have helped beavers thrive; eliminating them one by one in a Sherlock Holmes-style deductive reasoning.
Was the key connection coyotes, bears, bison or elk?
Thankfully for us, Marc Latham has written a new article about it for his Suite 101 Natural World Media channel; including a Greenygrey image; and it provides a more in-depth account of the documentary; its information; and the key link between wolves and beavers that has helped to replenish Yellowstone’s riverbanks.
