As global warming intensifies droughts, floods and wildfires around the world, scientists in western United States are turning to beavers to help reverse some of the damage.
Scientists at Utah's Boise State University and Utah State University are using satellite data to identify streams where once-eradicated beavers can be re-introduced to boost vegetation. They're also recording how water abundance and vegetation bordering those streams changes once beavers return — metrics of environmental health.
