Human intervention and balance in nature

It is about human intervention and the balance in nature.

Many of us are aware of the objections from farmers and hunters regarding the introduction of wolves in Yellowstone Park. The farmers complain of loss of livestock, although the loss is less than one percent, and of sportsman complaining of loss of gaming animals such as elks and deer. Some complain that they do not feel safe in the woods since the introduction of wolves and others see them as varmints. But how many of us are aware of the impact in the imbalance of nature without the wolves.

Since the loss of wolves in the wild, park rangers have had to cull elks and deer. The high population of elks overgrazed the habitats creating perpetual unnatural habitat. The intention of natural parks is to preserve nature but the loss of wolves undermines the intended purpose. The introduction of wolves has halved the population of elks. Elks graze the young aspen, willows and cotton wood turning them into clubbed and stunted plants. Released from the grazing pressure the young saplings grew vigorously allowing songbirds to find nesting habitat. Cotton wood growth helps stabilize stream banks and some stream banks are lush with willow and new vegetations. Beaver colonies have increase with the increase in new growth giving them ample nutritious willow stems to feed on and twigs to build dams. Beavers in turn create dams. These natural dams regulate the flow of water downstream helping other riparian that depend on the stream to survive in the drier months. Beaver dams also creates pond and marshes supporting fish, amphibians, waterfowls, wading birds, mink and a rich insect population to feed on. Wolf’s predation reduced the number of coyote bringing back the pronghorns. Wolves do not cover their kill and the carrions are food supply to scavengers such as bald eagles, ravens and bears.  Bison numbers have increase with a healthy grazing ground. We owe all these to the introduction of wolves in the wild.

By removing wolves in the wild we unintentionally remove a variety of other wildlife as nature intended. Since the introduction of wolves the parks are healthier. It demonstrates how human intervention could easily create an imbalance in nature.
