A wedge of gravel, mud, and grasses irrigated by treated wastewater outperforms all expectations as a prototype for climate change adaptation.

Experts monitoring 16 months of plant growth on a humpbacked levee experiment on the San Leandro shore, a project led by the Oro Loma Sanitary District, found early weed colonization followed by rapid dominance of target native perennial vegetation. “Native vegetation outcompeted weeds,” says Peter Baye, who designed the planting palette for this multi-benefit infrastructure project. The results were apparent during an October 2017 tour for international design teams looking at homegrown innovations in sea level rise adaptation as part of...

The number of Chinook salmon returning to Central Valley rivers is near record lows as a result of water management decisions made during the recent drought.

Returns of endangered winter-run Chinook salmon this year will be the second lowest this century—according to the Bay Institute’s Jonathan Rosenfield, the final 2017 estimate is likely to be less than 1,000 fish total, of which more than 80% were hatchery-spawned. Returning fish represent the survivors of the 2014 incubation period, when the US Bureau of Reclamation did not provide adequate cold water, and poor juvenile outmigration conditions during winter-spring 2015 resulting from reduced Delta inflow and outflow standards. Despite all this,...

“Sometimes doing nothing is the best option” is just one of the sometimes counterintuitive tips for post-fire restoration compiled by the Napa County Resource Conservation District in the wake of October’s North Bay firestorm.

A new web page simply titled “Fire” contains a suite of online resources for land owners and managers. From finding sources of invasive-free native plant seed to recommending that burned soils be left undisturbed wherever possible (so as to maintain their natural hydrophobic properties, which help prevent erosion), the website offers a trove of tips to help maximize the recovery of a healthy landscape in a series of “After the Fire” fact sheets that include titles such as Dos and Don’ts,...

A former Japanese-American-owned nursery/brownfield in Richmond is being transformed into a green infill development that includes affordable senior housing, a four-acre greenbelt with a daylighted creek, an urban forest, and easy connections to transit via the Richmond Central Greenway.

Tucked into a corner of the city next to the I-80 freeway and BART tracks, the “Miraflores” site was the heart of the Japanese-American nursery industry in the East Bay. From the early 1900s to 2006, three Japanese-American families operated a rose and carnation nursery there, one of about a dozen such nurseries in the Richmond-El Cerrito area, according to Bay Area historian Donna Graves. During World War II, the families were sent out of state to camps but returned...

Broad buy-in is the hoped for result of a proposed new landscape-level vision for conservation of the Delta.

For decades, government agencies, stakeholders, scientists, and planners have tried to develop a common vision for the future Delta, only to be stymied by environmental and economic politics. A new paradigm developed by diverse interests, however, proposes six regional conservation strategies to be achieved through collaborative, phased projects tailored to the needs of each sub-region, with a priority on improving public lands first. Proponents of the new framework say long-term conservation of the Delta is not a choice but an...

For the first time, the San Francisco Estuary has been mapped out for non-motorized watercraft.

From the Palo Alto Sailing Station to the Petaluma Creek Marina, the San Francisco Bay Area Water Trail program has established five maps that unify a network of “trailheads,” allowing boaters to access the entire Estuary. “The goal of the project is to improve and enhance access for non-motorized craft,” says Ben Botkin, Water Trail Planner. The back of each map provides information on the specific ecosystems of each region, serving to inform and inspire boaters to explore the varied...

In hot water due to climate change, many ocean fish are moving to higher latitudes or deeper waters to find the conditions they need to survive.

These include lobster, black bass, and Atlantic cod, all of which have supported iconic fisheries along the Eastern seaboard of the United States. “Ocean animals are moving ten times faster than animals fleeing climate change on land,” says Rutgers University marine biologist Malin Pinsky, whose Rutgers OceanAdapt website enables visitors to explore changes in marine species distributions over recent decades. These range shifts are causing headaches for fishing fleets, which are forced to head farther out to sea or hundreds of miles further from...

The California Legislature has made state history by passing SB-5, which acknowledges the importance of parks and climate-change resiliency for some of California’s most disadvantaged communities.

“Park access should not be considered a luxury. It is a right,” says Mary Creasman, California Director of Public Affairs for The Trust for Public Land. The bill—known as the California Drought, Water, Parks, Climate, Coastal Protection, and Outdoor Access for All Act of 2018—recognizes the importance parks play in a community’s quality of life as well as the lack of access to them in urban and disadvantaged communities. The bill provides definitions of “disadvantaged” and “severely disadvantaged” communities and provides...

Man’s best friend is being enlisted in efforts to detect the soil-born pathogen responsible for sudden oak death and other rapidly spreading plant and tree diseases.

Phytophthora is difficult to detect in nurseries, plant materials, and planting sites until it has done its damage. To develop early-detection options, H.T. Harvey and Associates are training a female cattle dog/border collie mix named Bolt to sniff out Phytophthora. Part of the Harvey Dog ecological-scent detection program, Bolt has accurately identified four species of Phytophthora in the lab. If her training in a natural setting is successful, Bolt could get to work helping minimize the spread of Phytophthora. Potential beneficiaries...

A new Bay Area screening tool helps me wrap my brain around a TMI project.

The day I began editing a monolithic overview of Santa Clara County’s Coyote Watershed I received a gift from my handler. He’d just thrown me for a loop by suggesting we describe not just Coyote Creek’s vast extent and myriad One Water management issues, but also its six sub-watersheds. I asked him to summarize the differences. Rather than composing a detailed memo, or searching water district literature for the materials, he logged into Bay Area Greenprint. Within hours I had...

Two Massachusetts restoration projects have recently returned close to 740 acres of commercial cranberry bogs to wetlands.

Like the Bay Area’s salt ponds, cranberry farming originally involved creating an artificial environment from a natural wetland through the installation of dams and weirs. The cranberries—a plant native to North America that naturally grows as a vine—were then trained to grow in mats on the water’s surface. A project on Tidmarsh Farms in Plymouth, Massachusetts included redirecting a natural stream that had been diverted into an agricultural canal back into its original channel and planting 6,000 Atlantic white cedars...

Simultaneous lawsuits filed against 37 fossil fuel companies by Marin and San Mateo Counties, along with the City of Imperial Beach, over sea level rise may open new front in climate battle.

 The suits, filed in California Superior Court, seek compensatory and punitive damages and other remedies for the ongoing harm that oil, gas and coal cause by contributing to global warming and sea level rise. A 2009 Pacific Institute study calculated that San Mateo has more property and people at risk from sea level rise than any California county, while in Marin more than 12,000 homes, businesses and institutions, with an assessed value of $16 billion could be at risk from...

Advocates for Alameda Creek are concerned that a new proposal to beef up passenger rail service between Stockton and San Jose would jeopardize water quality and wildlife habitat.

Niles-based Alameda Creek Alliance says the proposed expansion of the Altamont Corridor Express (ACE) passenger rail service might also bring increased freight train traffic to narrow, steep Niles Canyon, creating a situation that could lead to possible derailments and creek-contaminating spills. (A passenger train derailed into the creek in 2016.) Niles Canyon is the critical mid-point of complex watershed-wide work to reduce erosion, improve flood control, and restore steelhead to the creek. The Alliance and others are asking for a...

Small-scale conservation can have outsized ecological impacts, says an international group of researchers.

Among the small natural features that can have disproportionate ecological value are the bark of grand old trees, which has nooks and crannies that provide microhabitats for wildlife; patches of native plants alongside agricultural fields, which can provide some species with their only remaining natural habitat; and rocky outcrops, which nurture unique and diverse flora and fauna. Other benefits of conserving these modest yet influential—and often under-appreciated—landscape features include relative ease and affordability as well as compatibility with land uses...
