For 70 years, there had been no wolves in the park, and during that time, only elk had roamed freely, causing serious damage to the local flora due to their uncontrolled reproduction (all attempts to control their population by humans had failed).
Of course, fourteen wolves could not eat all the elk, but they forced them to be more cautious in choosing grazing spots and to avoid certain parts of the park. In these areas, vegetation began to thrive again.
As reported: Fakta.today
Within six years, the number of trees increased five-fold. Beavers appeared, which needed trees to build dams.
Standing water began to teem with otters, ducks, and fish. Wolves reduced the population of coyotes, which led to an increase in the number of rabbits and mice, attracting hawks, weasels, and foxes to the park.
Bears came to the park because they were able to drive wolves away from their prey.
The number of berries in the park increased.
Most amazingly, however, the wolves changed the course of rivers.
Their channels straightened and stabilized, and the erosion of the riverbanks decreased.
This happened because the wolves' impact on the elk led to an explosive growth of trees and grasses along the riverbanks, which strengthened them.
The geography of the park itself changed, and all this was due to fourteen wolves reintroduced less than twenty years ago.
