Beavers gain approval in North America

A recent article in the New York Times describes how beavers are gaining approval in the Western United States as a defence against a drier and warmer climate. For example, the article points out that, “Beaver dams, it turns out, have beneficial effects that can’t easily be replicated in other ways. They raise the water table alongside a stream, aiding the growth of trees and plants that stabilize the banks and prevent erosion. They improve fish and wildlife habitat and promote new, rich soil.”  Although the return of beavers has many benefits, there are some negative effects, many of which it appears can be managed. However, for some people it may take 10 to 20 years to fully understand what beavers mean for arid environments.
