Unleashing Beaver to Restore Ecosystems and Combat the Climate Crisis

Unleashing Beaver to Restore Ecosystems and Combat the Climate Crisis:

The creek bed, altered by decades of agricultural use, had looked like a wildfire risk. It came back to life far faster than anticipated after the beavers began building dams that retained water longer.

“It was insane, it was awesome,” said Lynnette Batt, the conservation director of the Placer Land Trust, which owns and maintains the Doty Ravine Preserve.

“It went from dry grassland… to totally revegetated, trees popping up, willows, wetland plants of all types, different meandering stream channels across about 60 acres of floodplain,” she said.

The Doty Ravine project cost about $58,000, money that went toward preparing the site for beavers to do their work.

In comparison, a traditional constructed restoration project using heavy equipment across that much land could cost $1 to $2 million, according to Batt.

Across North America and Europe, public agencies and private actors have reintroduced beavers through “re-wilding” initiatives. In California and Oregon, beavers are enhancing wetlands that are critical breeding habitat for salmonids, amphibians, and waterfowl. In Nevada, Utah, and New Mexico, environmental groups have partnered with ranchers and farmers to encourage beaver activity on small streams. Watershed advocates in California are leading a campaign to have beavers removed from the state’s non-native species list, so that they can be managed as a keystone species rather than a nuisance. And federal policy is shifting, too. The U.S. Fish and Wildlife Service sees beavers as “partners in restoration,” and the Forest Service has supported efforts like the Methow Beaver Project, which mitigates water shortages in North Central Washington. Since 2017, the USDA Natural Resource Conservation Service has funded beaver initiatives through its Aquatic Restoration Program.

[I believe they saw similar effects when reintroducing wolves. We should know by now that we should leave well enough alone.]
