Feds Coastal Research Crew Bucks Headwinds

Jim Cloern looked out of an airplane window one day and saw red streaks in the water; crimson patches darkening the grey-green shallows that are San Francisco’s South Bay. A superscientist with the US Geological Survey, he knew something big was happening. The color indicated a red tide, a harmful algal bloom...

Purse Opens for PCA Projects

Marsh restoration, Bay and Ridge Trail extensions, and urban park upgrades are among the types of projects eligible to receive funding through the 2019 Bay Area Priority Conservation Area (PCA) One Bay Area Grant Program. By March, aided by new mapping tools that can pinpoint regional landscape characteristics and needs, more than 36 cities, counties, agencies and non-profits had submitted letters of interest to the program, outlining a variety of projects that benefit one or more of the Bay Area’s 165 PCAs (see map opposite). Altogether, the grant requests totaled more than $19 million. Some of these projects may help vulnerable shoreline areas defend against sea level rise; others may make urban hardscapes more porous under atmospheric river downpours; still...

Youth Learn to Shift as the World Shifts

In a bright classroom in the hills of East Oakland, youth huddle in small groups building miniature rain-catchment models. Birdhouses serve as the base for a catchment system composed of a foil gutter, a straw pipe, and a Dixie cup rain barrel. Spritzes of water from a spray bottle generate rain-like condensation, which trickles through the system into the barrel. The eight middle schoolers gathered on this chilly Saturday morning are participating in a youth social-media ambassador training organized by a climate-readiness program called Mycelium Youth Network. In a few weeks’ time, they will build a life-size rain catchment system here at Pear Tree Elementary School. Lil Milagro Henriquez founded Mycelium Youth Network in late 2017, while fires engulfed California....

Widening Gyre of Ocean Challenges

Last year, researches working with SF State’s Estuary and Ocean Science Center installed an array of instruments to track underwater parameters. John Largier, a UC Davis professor of oceanography, says he expects clear trends and patterns indicative of warming and acidifying waters to become apparent in the data in about a decade. With nations making painfully slow progress in reducing their emissions of greenhouse gases, Largier thinks local efforts to boost the resiliency of the Bay ecosystem could be especially powerful.

Attention to Outcomes

The new Wetland Regional Monitoring Program, funded through an EPA Region 9 Wetlands Program Development Grant and managed by the San Francisco Estuary Partnership, aims to revolutionize the way that data is collected and shared about one of the Bay Area’s most fragile yet resilient ecosystems -- wetlands. “Monitoring data sits on shelves,” says Heidi Nutters...

High Road or High Water for Wildlife

While we were cooped up inside waiting out February’s storms, many animals were on the move. Cameras positioned along a creek in the Pacheco Pass wildlife corridor captured footage of animals passing through a culvert under a bridge on SR-152 that crosses Pacheco Creek. “We caught a bobcat on camera walking through the creek,” says Tanya Diamond...

Choppy Waters for Flow Rules

The winter kicked off with the State Water Resources Control Board’s December vote to adopt increased flow objectives for the southern Delta. The vote provoked an immediate volley of lawsuits, both from water users and from environmental organizations. “Governor Newsom has staked out turf against the Trump Administration,” says San Francisco Baykeeper’s Jon Rosenfield...

Putah Creek Pipeline for Salmon

“The dream is to reestablish a natural run of salmon in Putah Creek,” says UC Davis professor emeritus Peter Moyle. In 1972 Putah creek was a trickle of water between heavy machinery mining gravel for the campus roads. Moyle and others urged the university to cease mining and by the end of the decade the administration had designated a riparian reserve along the creek on campus. Since then there’s been an incredible increase in salmon....

SOS for Finicky Native

In 2016, restoration managers with The Nature Conservancy discovered that western sycamores planted along the Sacramento River had hybridized with the non-native London plane tree. The native sycamore is “kind of a messy tree,” says project manager Ryan Luster. “The branches break off and create cavities that wildlife love to use.” Concerns about the tree’s status first arose in the 1990s...

Getting a Bead on Table Salt

By Joe Eaton Microplastics are present in the San Francisco Bay, and at higher concentrations than Chesapeake Bay or the Great Lakes, according to a San Francisco Estuary Institute study led by Rebecca Sutton. There’s “a lot of uncertainty about potential impacts to people and wildlife,” she says.“[Miicroplastics are] a variable contaminant and challenging to interpret.” What we know is sufficient cause for concern: apart from their physical impacts, plastics can absorb other pollutants and some plastic ingredients are known endocrine disruptors. Cargill, the in-bay salt producer, says research is still determining the impact of microplastics on sea salt supplies but food safety remains a top priority.
