How wolves change rivers

This video chronicles the amazing effect that introducing just one species back into a habitat can have on restoring the natural environment.

In this video wolves being reintoruced to Yellowstone National Park serves as a case study. When they returned to hunt the white tail deer during 1995. The ecosystem changed with trees growing which supported migratory song birds. The beaver numbers also increased with their dams helping to increase the numbers of otters.

When they began to hunt coyotes the mice and rabbit populations increased. This meant more hawks, weasels, foxes and badgers moved in to hunt them.

The carrion created by the wolves saw bear numbers increase as they feed on this along with the berries on the new trees.

Most amazingly due to the river banks being supported by the new forests and collapsing less meant the rives stopped meandering as much.

It’s an amzing story of how a small number of wolves can lead to a major increase in biodiversity and a change in the geographical layout of an area.

This is an intersting concept which could have far reaching effects on how we conserve species and wild places.
