For years, beavers have been treated as an annoyance for chewing down trees and shrubs and blocking up streams, leading to flooding in neighborhoods and farms. But the animal is increasingly being seen as nature’s helper in the midst of climate change. California recently changed its tune and is embracing the animals that can create lush habitats that lure species back into now-urban areas, enhance groundwater supplies and buffer against the threat of wildfires. A new policy that went into effect last month encourages landowners and agencies dealing with beaver damage to seek solutions such as putting flow devices in streams or protective wrap on trees before seeking permission from the state to kill the animals. The state is also running pilot projects to relocate beavers to places where they can be more beneficial.
