Activists protesting the filling of some of California’s last remaining wetlands used steel tubes to lock themselves to a fill truck around 10:15 last night in the wick drain field one mile north of Willits on highway 101. A crowd of supporters gathered holding a banner that read: “Save Our Water, Stop Caltrans Now!”
Willits residents Earthworm, 18, and Feather were locked down for 8 and ½ hours to the immobilized truck, and another organizer, Ellen Faulkner, 74, was arrested by CHP. The action began a little after 10 pm on September 10.
All work came to a halt as some 20 trucks piled up behind Gate 6, the exit to the construction site where Caltrans is covering up thousands of wick drains with tons of fill, some of which may be contaminated with toxic materials. The massive project has drawn fierce criticism and persistent protests from a well-organized opposition who maintain the freeway is overbuilt, unnecessarily expensive and environmentally damaging.
Bypass opponents demand a two-lane, scaled down version of the bypass that would meet traffic needs while protecting precious wetlands and cost a fraction of the $300 million dollar, four-lane freeway proposed by Caltrans. Caltrans used false and misleading claims to exclude all consideration of 2-lane options. In addition, Caltrans failed to consider the effects of 55,000 thousand wick drains on the hydrology of the wetlands, according to Army Corp of Engineer’s letter of Aug. 16.
“We can still dramatically change the northern terminus of this project and protect a significant amount of wetlands. That’s why it’s so important that people take a stand and for the agencies to support us and demand that Caltrans shrink the project on the north end in the wetlands and riparian forest,” said Ellen Drell, board member of the Willits Environmental Center, one of two groups who filed suit on Aug.28 against Mendocino County for issuing a permit to haul fill without legally required environmental review under CEQA and the Surface Mining Act.
The County rescinded the permit, and hauling from the Mendocino Redwoods Products site stopped. Hauling resumed from a different site the following week. The possibly toxic material is being covered up before it can be tested by the State Water Board.
Regarding the lockdown, Drell said: “Young people are risking their lives for the future of the planet; the agencies could at least do their jobs by protecting the wetlands under their mandate.” The central mission of lead agency Army Corp of Engineers is to ensure “no net loss of wetlands”.

An alarming 50 percent of the world’s wetlands have been destroyed in the last 100 years, threatening human welfare at a time of increasing water scarcity, a new report said.
Wetlands serve as a source of drinking water and provide protection against floods and storms, yet they have been decimated to make space for housing, factories and farms or damaged by unsustainable water use and pollution.
“In just over 100 years we have managed to destroy 50 percent of the world’s wetlands,” said Achim Steiner, executive director of the United Nations Environment Programme.
“It is a startling figure,” he said at a UN conference in Hyderabad.
The report, compiled by an ongoing research project entitled TEEB, or The Economics of Ecosystems and Biodiversity, said coastal wetland losses in some regions, including Asia, have been happening at a rate of 1.6 percent per year.
“Taking mangroves as an example, 20 per cent (3.6 million hectares) of total coverage has been lost since 1980, with recent rates of loss of up to one percent per year,” said the report released Tuesday.
“We need wetlands because our existence, our food and our water is at stake,” said Ritesh Kumar of the environmental group Wetlands International.
Wetlands are known to cover about 13 million square kilometres (five million square miles) of the Earth’s surface, and are a natural sink for Earth-warming carbon dioxide, act as fish nurseries and are important tourist attractions.
In the United States alone, wetlands are estimated to provide $23 billion worth of storm protection every year, the report said.
The report was released at a conference of the UN Convention on Biodiversity, where environment ministers will hold three days of talks from Wednesday to try and raise funds to stop the decline of Earth’s natural resources.

The BP Deepwater Horizon oil spill temporarily worsened existing manmade problems in Louisiana’s salt marshes such as erosion, but there may be cause for optimism, according to a new study.
A study appearing online Monday in the Proceedings of the National Academy of Sciences found the 2010 spill killed off salt marsh plants 15 to 30 feet from the shoreline and this plant die off resulted in a more-than-doubled rate of erosion along the marsh edge and subsequent permanent marsh habitat loss. Vegetation farther from shore was relatively untouched by the incoming oil.
“Louisiana is already losing about a football field worth of wetlands every hour, and that was before the spill,” said Brian Silliman, a University of Florida biologist and lead author of the study. “When grasses die from heavy oiling, their roots, that hold the marsh sediment together, also often die. By killing grasses on the marsh shoreline, the spill pushed erosion rates on the marsh edge to more than double what they were before. Because Louisiana was already experiencing significant erosive marsh loss due to the channelization of the Mississippi, this is a big example of how multiple human stressors can have additive effects.”
Marshes are the life’s blood of coastal Louisiana because they act as critical nurseries for the shrimp, oysters and fish produced in these waters while helping to sequester significant amounts of carbon. They also protect coastlines from flooding and guard estuarine waters from nutrient pollution.
But the marshes have been suffering for decades as a result of the channelization of the Mississippi River, which has starved them from needed sediments to deter erosion.
Then came the oil spill.
Researchers observed minimal oil on the surfaces of grasses located more than 45 feet from the shoreline, indicating that significant amounts of oil did not move into interior marshes.
Instead, the researchers found that the tall grasses along the marsh edge acted as wall-like trap to incoming oil slicks, concentrating oil on the marsh edge. This concentration of oil on the shoreline protected interior marshes from oiling but worsened already extreme erosion on the shoreline. As oiled plants died, their roots that hold tight to the sediment perished as well. Already eroding sediment was now exposed to wave action without the effect of the gripping plant roots.
The result: elevated erosion rates for 1.5 years that averaged more than 10 feet of shoreline loss per year — double the natural rate for this area.
The encouraging results, Silliman said, included significant declines in the oil concentration on the marsh surface over 1.5 years and that unaffected, healthy marsh plants in the marsh interior quickly grew back into marsh die-off areas that had not yet been lost due to heightened erosion.
When the new marsh plant growth grew into the erosive edge of the marsh, Silliman said, the recolonization of the area by the gripping plant roots shut down the oil-elevated erosion rates and returned them to those seen at marsh sites where oil coverage did not occur.
The researchers also found that polyaromatic hydrocarbons, or PAHs, a carcinogenic byproduct of oil, was 100 percent greater at the Barateria Bay testing site than in reference marshes. This finding provides chemical evidence to support their visual observations that marshes in the affected areas were laden with oil while those in reference areas did not receive significant oiling.
By adding Biochar, a charcoal-based substance, to marshlands, Silliman’s team is also using new bioremediation tactics to try to break down PAHs into organic material. If this method is successful, he said, it could be used to supplement naturally occurring microbes in the marsh mud that already oxidize the oil carcinogen. The team is soon to publish those findings.
“This is a new idea applied toward cleaning up PAHs,” said UF chemistry professor Andrew R. Zimmerman, a co-author on the paper. “It’s possible there’s a bunch lurking at the bottom of the bay.”
