The Laguna de Santa Rosa held an open house on Wednesday, February 21, to celebrate the release of the Laguna de Santa Rosa Restoration Plan. Funded by a grant from the California Department of Fish and Wildlife with matching funds from Sonoma Water, this document examines six potential restoration projects in the Laguna de Santa Rosa watershed.

Presented by Neil Lassettre of Sonoma Water and Scott Dusterhoff of the San Francisco Estuary Institute (SFEI), this plan was several years in the making.

“So six years ago, we were here with folks from the public, many of you here in this hall, saying ‘Well, we were going to do this restoration planning effort.’ And here we are six years later, unveiling this restoration plan to you all. So this is really an exciting time for us,” Dusterhoff said.

Dusterhoff explained the two major phases of the project this way: “The first component was developing an understanding of how the Laguna used to look and how it used to function and the habitats that it was supporting. So that’s developing an understanding of the historical ecology,” he said. “And then after we understand how the Laguna used to look and how it used to function, we can understand the landscape change—so the magnitude of change from what was to what is. So that was part number one. Part number two then was using that information to develop this long term restoration vision—this long term idea of all of the habitats we want to bring back in the Laguna. So then, we took that vision and we dove deep on a few areas, and we came up with this master restoration plan,” he said.

One month into 2020’s shelter in place order, Virginia Holsworth and her family decided to change things up by walking in the opposite direction of their usual daily stroll through suburban Fairfield. That’s when she first encountered the amassment of sticks blocking the path’s adjacent creek, Laurel Creek.

She suspected the sticks meant the work of a beaver. Curious, she inspected the area, finding webbed footprints along the creek bank and chew marks on surrounding wood. Still, it wasn’t until she caught a glimpse of a brown slicked-fur-covered head that she was certain — she’d stumbled upon a beaver dam. A few days later, she saw the beaver family of four that gave rise to a lush green haven in her neighborhood.

For the next few months she watched cormorants and blue herons among the cattails and tules. Supposedly the creek even contained so many rainbow trout, a member of the community — illegally — caught 40 of them. The way the beavers and their dam had changed the landscape and reinvigorated the habitat enthralled Holsworth, and she became devoted to preserving them in her community.

Holsworth soon connected with Heidi Perryman, the Bay Area’s most ardent beaver activist and founder of the Martinez-based nonprofit Worth a Dam. Perryman warned Holsworth that the ecological wonder she’d found might be in jeopardy. The city of Fairfield had a permit to remove dams and had already, in 2015, obtained a permit to kill beaver.

Just a few months later, in fall 2020, the city public works department removed the beaver dam, citing the potential for flooding in the rainy season. Holsworth watched as the cattails wilted and birds quickly devoured the newly exposed crawfish.

New restoration plan for Laguna de Santa Rosa

Beavers can help California’s environment, but state policy doesn’t help them
