When, in 1995, fourteen wolves were released into the wild in Yellowstone National Park, scientists did not suspect that it will radically change the whole ecosystem of the park.

Wolves were not in the park 70 years and all this time there reigned deer, which in the years of uncontrolled reproduction (all the efforts of people to control their population did not bring success) caused heavy damage to local flora. Fourteen wolves, of course, could not eat all the deer, but they made the careful choosing a place for grazing and to avoid certain areas of the park. On the ground began to revive vegetation. For six years, the number of trees has increased fivefold. There beavers, trees which are needed for the construction of dams. The backwaters bred muskrat, ducks and fish. Wolves have reduced the population of jackals, which led to an increase in the number of rabbits and mice, and those in the party attracted to the park hawks, ferrets and foxes. The park came bears, as they were able to drive away the wolves from their prey or to eat up their leftovers. number of berries grown in the park.

But the most surprising, the wolves have changed the course of rivers. Their bed straightened and stabilized, reduced coastal erosion. It happened because the impact of wolves on the deer has led to the explosive growth of the trees and grass along the river banks, which led to their strengthening. It changed the geography of the park itself, and all thanks to the fourteen wolves released back less than twenty years ago.

That's not for nothing that the wolf is called "bearers of nature." But that would be to the point, the first time I read, very interesting.

Re: Wolves have changed the course of rivers



Wolf Pack

three of the weakest and most patients go ahead. [They set the pace if the pace will be set by the strong - these will be left behind and die. But] If the ambush - that kill going ahead. Even these weak wolves have trodden snow, and keep the strength to follow.
They were five mothers of wolves - mobile group of avant-garde. In the middle - 11 wolves [main value pack].
They were also the five mothers of wolves - rearguard
And behind all goes a bit farther himself leader. He needs to see the whole pack fully and to monitor, regulate, coordinate and give commands.

Re: Wolves have changed the course of rivers

Yeah, shocking nature of their systematic, well thought-out and perfection. When you evaluate this, all the more you realize how much a person his intervention resembles an elephant in a china shop
