Yes, beavers can help stop wildfires. And more places in California are embracing them

A vast burn scar unfolds in drone footage of a landscape seared by massive wildfires north of Lake Tahoe. But amid the expanses of torched trees and gray soil, an unburnt island of lush green emerges. The patch of greenery was painstakingly engineered. A creek had been dammed, creating ponds that slowed the flow of water so the surrounding earth had more time to sop it up. A weblike system of canals helped spread that moisture through the floodplain.
