Drakes Bay National Park Service Shuts Down Drake's Bay Oyster Company at Point Reyes National Seashore

You may have seen a previous post on the National Park Service's efforts to shut down this family oyster farm. This is one of those situations in which you become more annoyed at our government, the more you learn. This appears to be part of an effort to eliminate any type of private activity in the parks. In Washington DC this past week the NPS announced the plan to close a long-standing boat rental facility. (huh?) Here is a link to that story on Jack's Boathouse, which rented boats to JFK during his time in Washington.

Below is an excerpt from a New York Times Story on Drakes Bay.

Interior Secretary Ken Salazar  ended a longstanding and bitter dispute that pitted wilderness advocates against supporters of a Northern California oyster farm, announcing that the farm’s lease from Point Reyes National Seashore would end in late November as originally planned. An estuary known as Drakes Estero, where the oyster operation has existed for the last 40 years, will become a federally designated wilderness area.

In a statement, Mr. Salazar said, “We are taking the final step to recognize this pristine area as wilderness.” The Interior Department has given the farm 90 days to fold. More than a decade after the park was created on Point Reyes in 1962, Congress mandated that part of it be designated as wilderness; the section included Drakes Estero, a 2,500-acre rich marine estuary that is home to scores of seals. The oyster farm is the source of roughly 40 percent of California’s oysters and is part of a local food web that makes the surrounding Marin County area a mecca for locavores. 

In 2004, the oyster farm changed hands, and the lease was taken over by the Drakes Bay Oyster Company, which is run by a local rancher, Kevin Lunny. Mr. Lunny was notified that the lease was set to end this year, but indicated about six years ago that he hoped to have it extended. In the ensuing years, park service scientists questioned the farm’s environmental record, and were in turn accused of skewing the science to paint Mr. Lunny as a despoiler of the ecosystem. 

In an interview Thursday, Mr. Lunny said: “We’re trying to get over the devastation, the surprise and the disappointment. To have to deliver this message to our staff is beyond imaginable. To have to tell them they’re going to lose their jobs and their homes.” He said about 15 of the 30 oyster farm workers lived on the site with their families. The department indicated it would do what it could “to help employees who might be affected by this decision” but there is no provision for any payment to Mr. Lunny.

Illustrating the point that there usually are two sides to every issue,  three environmental groups — the Sierra Club, the National Wildlife Federation and the National Parks Conservation Association — immediately praised the decision. In an interview, Neal Desai, a West Coast representative of the Washington-based Conservation Association, said, “This is a very big gift the secretary has given the public.” 

While the policy issue was always whether to extend the lease, the parallel debate over park service science moved to the forefront in recent years. The park service had to backpedal on some of its original claims about environmental damage, and its subsequent scientific efforts were scrutinized by outside scientists who identified significant shortcomings. Repeated investigations confirmed many of these shortcomings, but never found that park scientists had engaged in outright scientific misconduct. The memorandum supporting the secretary’s decision played down the scientific issues, saying that the environmental impact statements that reviewed the science and recommended ending the lease had been helpful, but in no way indicating they were central to the decision.

The Po Boy Sandwich Rocks!

At our household we buy our oysters by the 100, ordering them by mail from our friends at Island Creek or Cedar Point in Connecticut. Both are linked on this page. But sometimes if you have only 5-6 people, 100 can be too many oysters on the half shell. And while oysters will keep in the styrofoam shipping container for several days if you recycle the ice packs, I often found myself seeking a different way to enjoy those last 20 oysters. On Christmas Day, I rediscovered the New Orleans classic 'Po Boy Sandwich'  and it rocked!

Classic Po Boy Sandwich
The Po Boy is easy to make. just shuck a half dozen oysters, dip them in egg, then breadcrumbs then fry.  Place about 6-8 fried oysters with chopped iceberg lettuce and sliced beefsteak tomato in a soft sub roll.  It melted in my mouth with wonderful mouth feel mixing the warm oysters with the cool lettuce and tomatoes.

Here is a link to an on-line recipe that uses fancier ingredients, but the sandwich still works amazingly well even if you stick to the basics.  I may even get out and buy a tabletop fryolater to make the frying process simple.

Oyster Shell Found Near Charlestown's Bunker Hill Monument!

Earlier we had written about how oyster reef structures were decimated for use to lower the acidity of fields and as roadbed material. See original post here. One of our eagle-eyed directors, Greg Hanson, found old shell near the Charlestown's Bunker Hill Monument as they were replacing sidewalk. This is another illustration of how the local oyster reefs must have been abundant if the town was finding and using shell for sidewalk substrates. This shell was beneath the old sidewalk so it has been there for a long time.

One side effect of removing the shell is that it removed habitat for young spat to attach to. And if you take away habitat you lower reproduction rates. This activity undoubtedly hastened the end of the once significant oyster population in Boston Harbor.

Alabama Oyster Restoration to Protect Island from Erosion

We came across this article on oyster restoration preserving shoreline in Alabama and thought it would make for thought-provoking reading given a recent editorial in the New York Times discussing oysters and their potential to protect Manhattan  from waves.  The original article can be found here.

Coffee Island, which has been slowly disappearing for decades, has quit shrinking. In fact, there are signs that the island, located just south of Bayou La Batre in the Mississippi Sound, is starting to grow larger. Credit goes to a “living shoreline” experiment dreamt up by the Nature Conservancy and funded by the National Oceanic and Atmospheric Administration. Using a federal stimulus fund grant in 2010, the groups constructed a series of oyster reefs around the southeast side of the island in an effort to combat erosion of the marsh.

As it happened, the Nature Conservancy began dumping 300 dump truck loads worth of oyster shells and 225-pound concrete balls into the water surrounding the island about two weeks before the Deepwater Horizon oil rig exploded and set off the BP oil spill. The goal was to recreate a natural system of oyster reefs that encircled much of Coffee Island long ago, reefs that served to break up waves as they washed ashore.

As those historic reefs disappeared, due to harvest by man and other factors, the island was subjected to the full onslaught of waves in the Mississippi Sound, which routinely top two feet. Each year, those waves whittled about 10 feet from the shoreline, all the way around the long and skinny island. Satellite images show the island was several hundred feet wider in 1990 than it is today.

As the oil began to drift across the Gulf in 2010, the newly completed, 1.5-mile-long reef on Coffee Island served as the inspiration for the much larger 100/1000 project, which aims to build 100 miles of oyster reefs and 1000 acres of marsh around Mobile Bay.  The Press-Register returned to Coffee Island on Thursday morning as a thunderstorm gathered over nearby Grand Bay and a rainbow arced across a darkened sky. It was the newspaper’s first visit since the Nature Conservancy kicked off the project shortly before the oil spill started.

The changes were easy to see.

The oyster shell and concrete reef balls had been placed about 90 feet offshore of the island, an attempt to help restore the shoreline to its position in the year 2000. At the time, the water between the reefs and the shore was nearly three feet deep. Today, it is about shin deep, thanks to a huge amount of sediment trapped behind the reefs. New marsh, primarily spartina grass, is beginning to grow in the sediment, evidence that the island is expanding.

The reefs have about 200 new oysters growing on them per square yard, according to surveys by biologists, a number that rivals or even exceeds natural oyster reefs. A control area on Coffee Island, where no reefs were erected, has no oysters growing in front of it and the marsh continues to recede. But on the new reefs, hermit crabs, stone crabs and oyster drills were abundant, crawling and sliding across the new oysters. Many of those oysters are just months old, growing from natural spat that set in April and May.


“It’s working exactly like it is supposed to. The sediment is getting trapped behind the reefs. And you can see the way the reefs are breaking up the wave energy. Look how much calmer it is behind the reefs, how the waves are getting knocked down,” said Jeff DeQuattro, who supervised the Coffee Island project for the Nature Conservancy. 
 
Rising up to where they just break the water’s surface at high tide, the reefs have effectively stopped the erosion on Coffee Island, DeQuattro said.“You can stand on the bottom behind the reefs now. It’s firmed up nicely,” he said, drawing a comparison between the soft mud that surrounded the island before the reefs were re-established.

DeQuattro said the project has been much more successful than he expected it to be. That suggests the rest of the 100 miles to be built for the 100/1000 project will have a big impact on Mobile Bay, he said.
“We’re building a reef and it takes time. With oysters, you don’t just dump some shell and, there you go, you have a reef. Creatures have to inhabit the nooks and crannies, crabs and fish. And they’re here. And oysters are growing,” DeQuattro said. “We’ve got all these little clumps of oysters here now. A lot of them are more than year old. We’ve got birds feeding on top of the reefs all the time, or even just hanging out on them. There is so much more life here now.”

Research Interests

My research interests span issues in ecology, fisheries and conservation biology, and ecological economics. I have used a variety of estuarine (oyster reef, seagrass, salt marsh, mud bottom) and marine (kelp bed, cobble-ledge) systems to examine how resource availability, habitat heterogeneity and predation risk affect population dynamics, community structure, and ecosystem functioning. Much of this work focuses on economically important species such as lobsters, cod, herring, monkfish, and oyster reef and seagrass communities, and consequently is relevant for fisheries and ecosystem management. My lab also focuses on how habitat degradation and restoration influence benthic community structure, population structure, and the transfer of energy to higher trophic levels. In addition, I am interested in how management initiatives such as closed areas, fishing gear modifications, and fishing effort reductions impact local habitat recovery, fisheries productivity, and the balance of resident and migratory life-history strategies for species such as cod. Finally, we are also examining a number of other important topics aimed at enhancing our ability to restore and conserve aquatic species and ecosystems: fish migratory behavior, population structure, and age validation; the economic value of ecosystem services associated with coastal habitats; seafloor habitat mapping and its role in ecosystem management; and the influence of climate change and biogeography on species range shifts, ecological interactions, and ecosystem functions.
