The key role that is played by the gray wolves in the preservation of the environment cannot be underestimated. By hunting the deer and the elk plus a couple of other animals the populations are kept in check. Subsequently the species of plant go up. Other types of animals stand to reap the benefits of the redistributed nutrients emanating from the carcasses of the animals. The animals that benefit in this instance are the scavengers and grizzly bears.
The net effect of reestablishing the gray wolves, issues of the unbalanced environment, defoliation and erosion in the parks are no longer existing. That sad state of affairs was due to the overpopulation of the elks and deers. These animals had the tendency of overgrazing on the willows and other plants. The resultant effect of this was that the structures near the riverbank and the soil were negatively affected.
The gray wolves are effective in ensuring that a delicate balance is achieved between the predators and the prey. The reason why this is the case is because the wolves are regarded as topping the list of aggressive predators. The previous removal of the predators led to a trophic cascade. This happened since the food webs experienced disruption. As a result of the reestablishment the elks transformed their patterns of behavior. The herbivores gave a wide berth to the locations such as the gorges and valleys that they knew the predators were prowling.
Bears, mice and the beavers took the advantage of the reestablishment of the gray wolves to make a comeback to the parks. The return was informed by the regeneration that the park underwent that meant that erosion was combated. Eventually plant life at the riverbank started thriving. As a result of stabilization in the parks’ riverbanks, the rivers and streams were able to change courses.
When the reestablishment of the gray wolves occurred, the scavengers were the main benefactors. What was left of the preys by the wolves benefitted the carrion feeders like the bears, eagles, and magpies. The approach that the scavengers employ id trailing the wolves at close distances and feed on the remains. When the food stressed winters come knocking, they have no reason to worry.
When the reestablishing of the gray wolves took place, the riparian vegetation went up. Apache trout that hitherto faced extinction were recovered as a result of the decrease of grazing that was not regulated.
