Beavers Could Help in Adapting to Climate Change

Beavers Could Help in Adapting to Climate Change

Beavers often get a bad rap for cutting down trees and building unwanted ponds on private property.




But Jen Vanderhoof of Washington State's King County Department of Natural Resources and Parks wants to help redeem this hard-working rodent's reputation.

"We're very obviously concerned about climate change, and I feel like beavers could help us," she said.

In the Northwest, warming temperatures and earlier snowmelt could cause water shortages in the summer. But Vanderhoof said that after beavers build a dam, "not only do you have more water being stored on the surface, but it's also filtering down into the groundwater, and so you're storing more water both above and below the surface that way."

Beaver ponds can also help slow water down as it flows through a watershed. That can help prevent erosion and reduce flooding after heavy precipitation.

Vanderhoof said the wet landscapes that beavers create can even help control wildfires.

"They are basically creating natural fire breaks," she said.

So she helps people find ways to manage beavers on their properties without killing or trapping them. And she said in some areas, introducing beavers can provide important climate benefits.

"They've got it all figured out," she said. "If we can just figure out how to work with them a little bit better."

Compost. Fly less. Reduce your meat consumption. Say no to plastic. These imperatives are familiar ones in the repertoire of individual actions to reduce a person's environmental impact. Don't have kids, or maybe just one. This climate action appears less frequently in that repertoire, but it's gaining currency as climate catastrophes mount. One study has shown that the reduction of greenhouse gas emissions from having one fewer child in the United States is 20 times higher—yes 2000% greater—than the impact of lifestyle changes like those listed above.

At this time of year, in Russia's far north Laptev Sea, the sun hovers near the horizon during the day, generating little warmth, as the region heads towards months of polar night. By late September or early October, the sea's shallow waters should be a vast, frozen expanse.
