Simple hand-built structures can help streams survive wildfires and drought

Conservationists, government agencies, scientists, and landowners are working together to restore streams using low-cost solutions from sticks, stones, and even beavers. Restoring these floodplains is important to help communities combat drought and wildfires. In Idaho, scientists relocated nine beavers to Birch Creek so they could help repair the dried-up stream. In three years, the beavers built dams, which helped the creek flow for longer in the summer. This method might not work everywhere, so scientists have also tested stone structures, which also proved effective at improving the ecosystem.
