US: Beavers will Help Salmon

13.10.2014

An unusual way to restore the ecosystem of american states Oregon, Washington and Utah was found by local biologists. On these territories water is a treasure. Beavers are those who know how to make it flow more slowly. Scientists decided to seek help from them. Usually farmers and beavers have war for precious moisture: farmers kill beavers mercilessly to prevent them from blocking irrigation channels. But scientists have found a more humane way of solving this problem.

US: Beavers will Help Salmon

Biologists catch beavers and take them to the sources of Washington river Yakima. About half of the animals adopts to the new place (part of them is being killed by predatores or returns home) and start building new homes. Thus makes river flow more slowly and prevents it from siltation downstream. Noreover, such dams are good for sheltering, feeding and restting for salmon and some other kinds of fish. Ecologists plan to use these methods to stop mass massacre of beavers (1-2 thousand beavers are being killed in Washington annually) and to improve the conditions for salmon fish populations. Today 126 rodents have already moved in 3 states.
