Wolves have a lot of side effects on the ecosystem. Due to the resettlement and the scientific monitoring at Yellowstone National Park (United States), many of which could be observed 1:1 and even the experts were amazed. The video explains that the presence of wolves have avoided the deer certain places and so able to grow vegetation. So trees grew in some places within 6 years 5 times as high as before. So first birds beavers and many other animals came back later. And the Beavers are just like wolves ecosystem engineers, which again creates habitat for other species. The carrion left behind the wolves was food for smaller predators, such as birds of prey and foxes, but also bears. The bears, about 80% were vegetarians, promoted especially by the returning beer bearing bushes, which had abgeäst the deer before. Finally, the wolves have even acted on the geological conditions. Because by the stabilizing effect of plant roots, there were fewer landslides and rivers were stable, there was less erosion. These are all additional reasons why we should learn to live with the animals! Thanks to Noisy Lärmi Miller for the tip!
