Topic: 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.

The rice farmer John Brennan … [is] collaborating with the scientist Jacob Katz to turn a piece of the Sacramento Valley, specifically in the Yolo Bypass, into a floodplain that can be home to baby Chinook salmon during the winter months, as they make their way down the river system to the Pacific. Their experiment, aptly named the Nigiri Project (in reference to the beds of seasoned sushi rice draped in little blankets of raw fish), involves flooding Brennan’s rice fields once the grain has been harvested so that the depleted stalks can decompose in the water, thereby making those nutrients available to bugs and plankton, which then serve as food for schools of growing salmon.

We’re putting up levees so that it won’t settle on floodplains. We’re filling in wetlands so that we can build or farm on top of them. We’re cutting down mountain forests that act as water towers, generating water and releasing it slowly.

Delta Warning

15-minute DVD that graphically portrays the potential disaster should a major earthquake hit the Sacramento-San Joaquin Delta. “Delta Warning” depicts what would happen in the event of an earthquake registering 6.5 on the Richter scale: 30 levee breaks, 16 flooded islands and a 300 billion gallon intrusion of salt water from the Bay – the “big gulp” – which would shut down the State Water Project and Central Valley Project pumping plants.


Water on the Edge (60-minute DVD)

Water truly has shaped California into the great state it is today. And if it is water that made California great, it’s the fight over – and with – water that also makes it so critically important. In efforts to remap California’s circulatory system, there have been some critical events that had a profound impact on California’s water history. These turning points not only forced a re-evaluation of water, but continue to impact the lives of every Californian. This 2005 PBS documentary offers a historical and current look at the major water issues that shaped the state we know today. Includes a 12-page viewer’s guide with background information, historic timeline and a teacher’s lesson.

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.
