Something to celebrate: Beavers return to Sonoma Creek

SONOMA ECOLOGY CENTER

It’s been a long summer of extreme drought conditions in Sonoma Valley. In what seems like a steady stream of dire news for our watershed one glimmer of good news stands out: beavers are moving back into Sonoma Creek.

The return of these charming dam builders isn’t quite breaking news – since 1993 beavers have slowly made a comeback in Sonoma Valley. But this year, in the middle of our peak dry season, their increasing presence is something for celebration. From the perspective of drought resiliency and water retention in our watershed we’re observing how beavers are a positive factor in keeping what water we do have flowing in our creek beds and reducing hydrological impacts of water rushing through the main stem of Sonoma Creek.

Their natural impulse to build dams and create ponds is a major factor in retaining refuge habitat for species that rely on water to survive. Beavers provide refuge habitat for endangered salmonids, crawdads, California roach, Sacramento suckers, frogs and the endangered California freshwater shrimp which rely on deep pools and submerged, structural habitat like fine tree roots which are often present in the structure of a beaver dam. Any animal, insect, or crustacean that requires water to live in our creek is something that benefits from the damming that the beavers do.

A struggling California marsh gets an overhaul to prepare for rising seas

Alastair Bland, AUDUBON MAGAZINE

The restoration of the Sonoma Creek in the San Francisco Bay Area not only corrects problems of the past, but also looks to the future.

The sun shines meekly through a veil of morning fog and wildfire smoke while several figures in orange vests, hard hats, and face masks move slowly through a marsh on the north shore of San Francisco Bay. Wielding brooms, they jab lightly at the vegetation, ruffling the tufts of native pickleweed. As biological monitors, their job is to flush out small animals—especially the endangered salt marsh harvest mouse—and usher them from the path of a rumbling excavator, which is about to dig a deep groove in the slick mud.

It’s early October at the mouth of Sonoma Creek, where an unusual conservation project that broke ground five years ago is nearing the finish line. Audubon California and partner agencies are turning what was once a 400-acre stagnant backwater into a thriving wetland ecosystem that will serve as a refuge from rising seas for decades to come.

This revitalization of Sonoma Creek marsh is more a story of creation than one of restoration. The place is a product of the Gold Rush era, when torrents of unearthed sediment choked the Sacramento River system and later settled downstream. While hawks, grebes, and plovers made use of the area, which is managed today as part of the San Pablo Bay National Wildlife Refuge, the marsh wasn’t exactly a haven. The unnatural mud buildup was too rapid, preventing the formation of the channel systems that typically run through wetlands like arteries and allow a healthy water exchange with adjacent bays and estuaries. “If this was a natural marsh, it would look like a lung—it would breathe,” says Andrea Jones, director of bird conservation at Audubon California.

Gualala River estuary conservation effort takes a $2.1 million step toward success

THE MENDOCINO BEACON

Sometimes it does take a small group of passionate locals to conserve a river estuary forever.

In 2017, 113 acres of scenic and environmentally sensitive coastal wetlands and adjacent uplands surrounding the Gualala River went up for sale for the first time in over 70 years. The community came together, signaled their desire for open space with sensitive public access versus development. The movement began.

Thursday, the Redwood Coast Land Conservancy announced that it has received three grants totaling over $2.1 million for the Gualala River Mill Bend Conservation Project that they are stewarding for the community. The US Fish & Wildlife Service awarded the project $1 million through the National Coastal Wetlands Conservation Program. An $845,000 award came from the California Natural Resources Agency through the Environmental Enhancement & Mitigation Program. The third grant award of $300,000 came from the California State Coastal Conservancy and will allow for initial site assessment and a conservation master plan.

“(Redwood Coast Land Conservancy) feels fortunate to share conservation goals with our federal and state partners. The Mill Bend project will clean up a degraded area from a century of timber mill use and enable wildlife habitat restoration, estuary enhancement for steelhead and salmon and thoughtful public access including continuing the California Coastal Trail,” said Kathleen Chasey, project manager for the conservancy.

Founded in 1992, the Redwood Coast Land Conservancy is the local land trust for the Mendo-noma coast. The conservancy has taken the lead role to secure the funds for the Mill Bend acquisition, planning and stewardship and is conducting a $2.7 million “Campaign to Preserve Mill Bend.”

“We plan to raise enough funds through additional smaller foundation grants and community contributions to preserve and protect this vital property in perpetuity, said President Christina Batt.

In addition to the three grants awarded, Redwood Coast Land Conservancy must raise $600,000 for stewardship since funders for the acquisition require substantial stewardship funds be in place to demonstrate adequate resources to manage and protect the property forever. The group has been quietly contacting key donors and has lined up $300,000 in lead gifts. The official launch of the campaign to raise $600,000 was to begin in March but was postponed to now because of the COVID-19 virus outbreak. Contributions toward the Mill Bend campaign are welcomed.

More information about RCLC and the Campaign to Preserve Mill Bend can be found on the RCLC website at www.rclc.org. Contributions to RCLC can be made via its website or by sending a check to P.O.Box 1511, Gualala, CA 95445

Return of long-lost bees creating a lot of Presidio buzz

Peter Fimrite, SAN FRANCISCO CHRONICLE

The sudden appearance of buzzing insects around Brian Hildebidle’s feet as he surveyed a dune restoration project in the Presidio last week startled him and prompted alarming visions of volunteer workers fleeing from angry yellow jackets.

The stewardship coordinator for the Presidio Trust was about to run when he noticed the insects were a grayish color and swirling in a strange pattern close to the ground.

“I was really curious because I had never seen that flying pattern,” said Hildebidle, who leads volunteers on weekly weed-pulling and planting expeditions and is quite familiar with the park’s bug denizens.

The insects, which he said numbered in the hundreds, turned out to be silver digger bees, a rare sand-loving species that had not been seen in San Francisco in significant numbers for the better part of a century.

Students work to protect environment

John Jackson, PETALUMA ARGUS-COURIER
The success of the United Anglers of Casa Grande High School program has created the program’s greatest challenge.
The United Anglers of Casa Grande is a nonprofit educational organization located on the Casa Grande High School campus. Members of the organization are students who learn about fisheries, especially salmon and steelhead, and promote environmental awareness and activism through hands-on habitat restoration. United Anglers students operate and maintain a state-of-the-art conservation fish hatchery on the campus.
Interest in the program has exploded in recent years from around 30 students to more than 100, and now includes participants from Petaluma High School as well as Casa Grande.
Since the United Anglers program is a nonprofit and must raise all its own funds, the challenge comes in raising enough money to support the increase in membership, particularly at a time when the recent fires and disasters in other parts of the country are vying for benevolent contributions.
“I’m torn,” said program director and teacher Dan Hubacker. “We depend on support from families and businesses, but at the same time how do you ask them for donations after so many people have been affected by the fires?”
But Hubacker also said he feels an obligation to honor those, like himself, who have benefited by the program by keeping it going.

Flying insects have been disappearing over the past few decades, study shows

Ben Guarino, THE WASHINGTON POST

Helping these tiny helpers can take only a small effort, he said. Habitat restoration can be as simple as a garden with plants that flower throughout the year. Unlike mammals, insects don’t require vast tracts of land to be satisfied — a back yard blooming with native flowers will do.

Not long ago, a lengthy drive on a hot day wouldn’t be complete without scraping bug guts off a windshield. But splattered insects have gone the way of the Chevy Nova — you just don’t see them on the road like you used to.
Biologists call this the windshield phenomenon. It’s a symptom, they say, of a vanishing population.
“For those of us who look, I think all of us are disturbed and all of us are seeing fewer insects,” said Scott Black, executive director of the Portland, Ore.-based Xerces Society, a nonprofit environmental group that promotes insect conservation. “On warm summer nights you used to see them around streetlights.”
The windshield phenomenon is not just a trick of Trans Am nostalgia. A small but growing number of scientific studies suggest that insects are on the wane.
“The windscreen phenomenon is probably one of the best illustrative ways to realize we are dealing with a decline in flying insects,” said Caspar Hallmann, an ecologist at Radboud University in the Netherlands. Hallmann is part of a research team that recently waded through 27 years’ worth of insects collected in German nature preserves.
Between 1989 and 2016, according to a report published Wednesday in the journal PLOS One, the biomass of flying insects captured in these regions decreased by a seasonal average of 76 percent.
