Topic: Wetlands

Overview

Wetlands

Wetlands are among the most important ecosystems in the world. They produce high levels of oxygen, filter toxic chemicals out of water, reduce flooding and erosion and recharge groundwater. They also serve as critical habitat for wildlife, including a large percentage of plants and animals on California’s endangered species list.

As the state has grown into one of the world’s leading economies, Californians have developed and transformed the state’s marshes, swamps and tidal flats, losing as much as 90 percent of the original wetlands acreage—a greater percentage of loss than any other state in the nation.

While the conversion of wetlands has slowed, the loss in California is significant and it affects a range of factors from water quality to quality of life.

Wetlands still remain in every part of the state, with the greatest concentration in the Sacramento-San Joaquin Delta and its watershed, which includes the Central Valley. The Delta wetlands are especially important because they are part of the vast complex of waterways that provide two-thirds of California’s drinking water.

San Francisco Bay restoration plan updated amid funding surge

Proponents of a new plan to rehabilitate San Francisco Bay say they hope to make significant gains in the coming years because of millions of dollars in new federal funds. The estuary, the largest on the west coast of North America, covers 60,000 square miles from the foot of the Sierra Nevada to the Golden Gate, including the Sacramento-San Joaquin River Delta. The estuary and the surrounding mountains, which hold about half of California’s water supply, are home to highly diverse ecosystems, including 100 endangered and threatened species, and support a multi-billion dollar economy.

Talks on Highway 37’s future underway as sea-level threat looms

For generations, the 21-mile route linking Marin County and Vallejo has been essential for commuters and travelers. Now Highway 37 has become something more — a centerpiece in a growing debate on how the Bay Area and California should respond to climate change and when politicians should bite the bullet to spend the billions of dollars needed to deal with it. Caltrans is studying a plan to widen a traffic-prone, 10-mile stretch of the highway at a cost of nearly half a billion dollars while it comes up with a longer-term fix. But some advocates say they should skip that step while significant funding is available and do what all parties agree will eventually need to be done by elevating the road.

Bay Area entrepreneur envisions new purposes for land, ways to save planet

One day while [civil engineer James Levine] was looking out at the bay from his Emeryville office, Levine was struck by the steep unnatural riprap shoreline surrounding most of the bay that discourage wildlife from gathering there. He also thought about the many tons of sediment that needed to be dredged from the bay so that big ships could pass — and what he could do with that fill to encourage wildlife habitat elsewhere. Thus was born the Montezuma Wetlands Project in Solano County, a private initiative begun in the early 2000s that addresses two problems: the historic loss of wetlands and how one can responsibly dispose of millions of cubic yards of sediments dredged annually from San Francisco Bay Area ports, harbors and channels.

New research: Atmospheric rivers help coastal wetlands build up sediment

Extreme precipitation from hurricanes and atmospheric rivers can lead to increased flooding in the world’s coastal zones, where more than 630 million people reside. Tidal marshes act as important buffers in these areas, absorbing the initial impact of storm surges and strong winds. In addition, tidal marsh ecosystems rely on storm events to deposit sediments that help with marsh accretion. In a new study, Thorne et al. focused on tidal marsh accretion and elevation change in the San Francisco Bay after an atmospheric river event in 2016-2017.

Pacific Flyway

The Pacific Flyway is one of four major North American migration routes for birds, especially waterfowl, and extends from Alaska and Canada, through California, to Mexico and South America. Each year, birds follow ancestral patterns as they travel the flyway on their annual north-south migration. Along the way, they need stopover sites such as wetlands with suitable habitat and food supplies. In California, 90 percent of historic wetlands have been lost.
