The only updates are that the Loggerhead Shrikes are no longer seen nesting on the western shoreline following cleanup work that was performed. And the Harriers have not been seen nesting at Alameda Point in recent years.
The refuge remains a unique wildlife habitat that deserves permanent protection.
On December 16, from before dawn until dusk, hundreds of hardy volunteer birders trekked through parks, neighborhoods, wetlands, and woods to count birds during the Audubon Society’s annual Christmas Bird Count in the East Bay. In Alameda, three teams fanned out across the city. One team went to Alameda Point.
Carrying binoculars, spotting scopes, a clipboard, and bird reference books, bird watchers were participating in the annual Christmas Bird Count (CBC) organized by the Golden Gate Audubon Society. While the total number of birds tallied during the count helps to fill out the picture, the main goal of the day was to identify as many different species of bird as possible.
“This is not just about counting birds,” said Gary Langham, Audubon’s chief scientist. “Data from the Audubon Christmas Bird Count are at the heart of hundreds of peer-reviewed scientific studies and inform decisions by the U.S. Fish and Wildlife Service, the Department of the Interior, and the EPA. Because birds are early indicators of environmental threats to habitats we share, this is a vital survey of North America and, increasingly, the Western Hemisphere.”
The Alameda Point team was led by Alameda resident Leora Feeney, of Friends of the Alameda Wildlife Refuge, and John Luther, one of the most experienced bird watchers in the state. Linda Vallee was responsible for tallying results on her clipboard list of bird species as they were reported.
John’s 50 years of observing birds in every California county is evident in his quick identifications and economy of movement with his spotting scope. “There’s a Common Loon…and…it just went under…there it is…turn around(as if speaking to the bird)…it’s… a Red-throated Loon,” he would say. “White-crowned Sparrows – two.”
One thing you learn about bird counting etiquette, if you’ve never been to one of these events, is that you should not chit chat with someone while they are staring intently through a scope. They could be trying to systematically count hundreds of birds by adding groups of 5 or 20 or 100 in their head as they keep landmark references in focus. At one stop, attention turned to Breakwater Island on the other side of the Alameda Point Channel where an unusually high number of California brown pelicans (for this time of year) were roosting amongst the cormorants. Leora counted 304 pelicans.
Continuing around the refuge, there were Burrowing Owls, Killdeer, a Horned Lark, a Peregrine Falcon perched on a fence, and a much smaller falcon not commonly seen around Alameda Point called a Merlin. Often the birds were in fast moving groups darting around, landing, skip, skip, pick, pick, and off they flew.
The biggest surprise came at the thick stand of willows at the north boundary of the refuge. There, just inside the branches was a Great Horned Owl, a bird that Leora said she had never seen in eight years of doing twice-monthly bird surveys on the refuge. Even more surprising was how approachable the owl was as it was being photographed, slowly turning its its head 180 degrees, appearing fearless.
After leaving the refuge, the team made other stops at the Seaplane Lagoon, the Inner Harbor on the south side, Breakwater Beach, and the neighborhood where the Big Whites are located. The Big Whites neighborhood has a very good variety of mature trees, ideal for bird watching.
The preliminary total for all species sighted in the Oakland count area on Sunday (the 15 mile circle that is centered at Lake Merritt and includes Alameda) was 177 species. According to GGAS Communications Director Ilana DeBare, “That is pretty much in line with a normal ‘good’ year. There were 29 teams total, with well over 100 participants.”
“Christmas Bird Counts combine many of the things Golden Gate Audubon stands for,” said GGAS Executive Director Mike Lynes. “It’s a fun day with a serious purpose. Everyday volunteer bird-watchers become citizen scientists, contributing data that will help inform future decisions about Bay Area bird life and habitat.” The San Francisco Christmas Bird Count is on December 27.

Once upon a time there was talk about a national wildlife refuge at Alameda Point. It was included in the reuse plan for Naval Air Station (NAS)-Alameda that was accepted by the Department of Defense. It was added to Alameda’s General Plan. The US Fish & Wildlife Service was poised to be the owner and caretaker of the refuge.
But after talks broke down between the Navy and US Fish & Wildlife Service nearly a decade ago, the Navy arbitrarily decided to give the land to the Department of Veterans Affairs (VA) for a clinic and columbarium. The VA is counting on the City of Alameda to give them an additional 70 acres of land early next year so that their clinic can be located further away from the nesting site of the endangered California least terns. This would bring the VA’s property to roughly 620 acres, even though they need only 110 acres.
The city should impose a condition on this land deal: Before the city changes its reuse plan footprint to accommodate the VA, the city should insist that the Navy place a conservation easement on the 511 acres that the VA does not need. A conservation easement would lay the groundwork for creation of a wildlife refuge or wildlife conservation area to be operated by another agency.
The benefits of creating a wildlife refuge at Alameda Point go beyond environmental stewardship. They also include economic benefits to Alameda and the region. The Golden Gate Audubon Society (GGAS) understood the economic angle back in 1995 when they were advocating for creation of a wildlife refuge. To provide substance to their views, they commissioned a study by Robert Hrubes and Associates that was released in March of 1995. It’s called “The Potential Economic Benefits of the Proposed Alameda National Wildlife Refuge: An Overview.” The conclusion of the 1995 study—that a wildlife refuge will complement economic development—still holds true today.
The study went on to extol the intersecting virtues of wildlife habitat protection and economic value. “While important in their own right, the benefits that would be generated by establishment of the wildlife refuge are not limited to habitat and species protection,” stated Hrubes and Associates. “[T]here are indeed potential economic benefits that could derive from a wildlife refuge/day-use recreation area located in the central Bay Area. That is, the wildlife refuge proposal is not an ‘either/or’ choice between environmental quality and economic development. Rather, it constitutes a land use that not only will take optimal advantage of the environmental attributes the site has to offer but also will generate economic activity that benefits the local region. Further, it will enhance the economic value for development of the remainder of the NAS.”
The current proposal for the VA to own and control the 511-acre refuge area next to their 110-acre medical clinic and columbarium makes it all but impossible for this area to become the urban wildlife oasis that it could be. The VA’s proposed project map makes this clear by wiping out the words “Wildlife Refuge” and replacing them with “VA Undeveloped Area.”
At this stage of the environmental review process, the only significant environmental requirement that has been imposed on the VA is that they provide predator management, housekeeping, and record-keeping for the California least terns during their four-and-a-half-month nesting season at Alameda Point from April to mid-August. This is because the Biological Opinion issued by the US Fish & Wildlife Service in the summer of 2012 focused only on one species – the least tern – due to its listing as an Endangered Species. It remains to be seen whether the VA and Navy will prepare a full Environmental Impact Statement (EIS) as typically required for a federal project of this size and scope. The National Environmental Policy Act provides for an impact report that is similar to California’s Environmental Impact Report. If the Navy and VA perform an EIS, they will then have to look at impacts to other species (such as the burrowing owl), habitat values, climate and traffic impacts, as well as identify alternative sites for all or part of their project.
However, based on public statements from the VA about their timeline for construction, it does not appear that they have any intention of doing a full EIS, and thus their environmental commitment will be limited. This will mean that rather than adding grasslands to perimeter areas that already have pockets of grasslands between runways and taxiways in order to divert hawks and other avian predators away from nesting terns, they will keep the refuge looking as much like a fenced-in stadium parking lot as possible (like it has been for the past decade). The pretext is that it removes habitat for predators, but in this case they would be torturing the concept by making the tern nesting site so conspicuous that it will invite predation. Virtually all of the least tern predation events have been from flying predators—like the peregrine falcons that come from miles away on the other side of Alameda.
The real reasons for maintaining the industrial look are to reduce maintenance and capital costs, and to exploit the paved areas for revenue-generating uses that don’t require construction. They have already said they will use the area for emergency preparedness training, disaster staging, and storage of supplies.
Over 180 different species of bird have been spotted on the refuge at one time or another. Some of the wetland area can easily be expanded and linked permanently to the Bay. Grasslands could be added. Instead, what we can expect to see added are auto driving events and RV shows.
Early in 2013, the Alameda city council will play a pivotal role on whether the VA is able to permanently kill the wildlife refuge vision. The city council must vote on an amendment to its no-cost conveyance deal with the Navy in order to allow the VA project to move forward. By their action, the city will decide whether the 1996 Community Reuse Plan for Alameda Point will be amended to remove the wildlife refuge as a goal, or if it remains.
Killing the wildlife refuge is not only a bad idea for the environment. It’s a bad idea for the economy.

Some of the toxic contamination at Alameda Point is not the result of Naval operations.
The Navy began cleaning up contaminated soil at five hot spots in the airplane runway area of Alameda Point in October. Cleanup Site 33 – on the area commonly referred to as the wildlife refuge – encompasses the southern end of the main north-south runway and adjacent tarmac, and is near the Least Tern nesting site and a wetland area.
The soil here became contaminated with PAHs (polycyclic aromatic hydrocarbons) before it ever became part of Alameda Point. The fill material used for creating this land mass was dredged from the Oakland Estuary primarily between 1936 and 1941 by means of a pumping system. It was contaminated by a coal gasification plant, which operated in Oakland around 100 years ago that disposed of waste into the waterway. Some of the sediment contamination may also have originated at the Pacific Coast Oil Refinery that once operated on the west end of Alameda.
The potential health risk from PAHs, normally through ingestion of dust, has been part of cleanup evaluations for over a decade. The Navy and regulatory agencies agreed to the EPA’s residential soil standard in 2001.
PAH soil sampling began in 2002 at 300 locations throughout Alameda Point, including Site 33, producing over 1,200 samples. The 500-plus acre wildlife refuge parcel had 79 soil borings that produced 316 samples. Five boreholes exceeded residential use standards.
A 2008 report recommended additional testing at Site 33 that was done in 2010, leading to the current cleanup work at the five hot spot areas.
Over the past 22 years, more than 28 environmental studies have been conducted on the “refuge parcel,” looking at everything from volatile organic compounds, petroleum byproducts, PAHs, pesticides, PCBs, dioxins, explosives, metals, and radium. They analyzed surface sediment, soil, surface water, underground water, manhole sediment, and animal and plant tissue samples. Aerial photographs were also reviewed.
Talks between the Navy and US Fish & Wildlife Service for establishing a national wildlife refuge reached an impasse a decade ago, before many of these studies were completed, due to Fish & Wildlife’s concerns about liability for unforeseen cleanup expenses.
Today, the refuge parcel is slated to be transferred to the US Department of Veterans Affairs. Only about 40 acres of the refuge will be needed for their national cemetery and clinic if plans are approved to move most of the project northward onto the city’s Northwest Territories parcel.
The Navy will present an update on Site 33’s soil cleanup at the next Restoration Advisory Board meeting, 6:30 PM, Thursday, Nov. 8 at 950 West Mall Square, Community Conference Room at rear of building.
The successful recovery effort for the once endangered California brown pelican is evident every summer through fall on Breakwater Island, an area which forms the beginning of the Alameda Point Channel leading to the ship docks and Seaplane Lagoon. The breakwater is a wall of boulders built up from the Bay floor to reduce wave action in the harbor.
California brown pelicans were listed as an endangered species in 1970. The pesticide DDT was identified as the cause of their decline. It caused reproductive harm, and altered the birds’ calcium absorption, which led to thin eggshells that would break under the parents’ weight. Use of DDT was banned in the United States 1972.
A recovery effort was launched in the 1970s on Channel Islands National Park off the coast of Santa Barbara. The only breeding colonies of California brown pelicans in the western United States are within Channel Islands National Park on West Anacapa and Santa Barbara islands.
In the summer and fall, the brown pelicans can range from nesting colonies in Mexico and the Channel Islands all the way up to British Columbia. Alameda Point’s Breakwater Island is the largest roosting site in San Francisco Bay. A safe, secure roosting area is essential for pelicans to rest, preen, dry their feathers, maintain body temperature, and socialize.
When the Naval Air Station was still active, the Navy enforced restrictions against boats landing on the Island and posted signs that warn against disturbing the birds. Since the base closed, there has been no one to enforce regulations against disturbing the pelicans.
The California Brown Pelican was removed from the Endangered Species List in 2009 after an almost 40-year recovery. There is currently no plan to look out for the welfare of these magnificent birds after the base is transferred out of Navy ownership. One way to ensure adequate protection and provide public education and appreciation of this unique ecological asset is to have it be part of an “Alameda Point Wildlife Conservation Area.” The East Bay Regional Park District would be an excellent agency to manage it; they already have a marine conservation area at nearby Crab Cove.
The brown pelican pictured above with a leg band reading “K69” was brought to the International Bird Rescue clinic in Cordelia near Fairfield, CA on July 9, 2012 in a thin and weak condition. It is less than a year old. After a one-month rehab, it was released at the Elkhorn Slough Estuarine Reserve near Watsonville on August 10. A blue band on a pelican leg means it was given a helping hand at one of the two clinics operated by International Bird Rescue – located in the San Francisco Bay Area and Los Angeles. Some of their released pelicans have been spotted in Oregon and Washington. If you see a pelican with a blue leg band, they’d like to hear about it.
The least tern nesting season ended in mid-August much as it usually does – a lonely and dangerous place for young terns. There were three of four pairs of adults flying back and forth with food for their young chicks. These late nesters are often the ones whose eggs or chicks were attacked by avian predators and have re-nested. Their vulnerability is only compounded as the weeks wear on because the rest of the adults and their flight-ready young have left, leaving the remaining families without the strength of numbers to mob a predator.
Volunteers arrived at the nesting site on September 9th to begin gathering up the oyster shells, wooden A-frame shelters, and clay tiles randomly arrayed about the site that serve as camouflage and chick shelters from predators.
They also carefully gathered up over 300 numbered nest markers that were placed near the nests by the US Fish & Wildlife biologist. A tern nest consists of a small depression in the gravel – no twigs. The four-inch white nest marker rings are set upright in a plaster base and each have a number. This allows Fish & Wildlife to monitor breeding success and record predator activity such as taking of eggs. Between now and next April when the terns return, the site’s substrate of gravel will be groomed and weeds removed.
On September 16th, volunteers returned to continue gathering oyster shells and taking care of another task: Removing a pernicious weed call stinkwort. It is virtually impossible to eradicate stinkwort with herbicides and must be removed by hand. Pulling the tough sticky weed out by its roots is usually not successful, and volunteers were limited to chopping the weed off at its base. If not removed by fall, the weed would begin releasing seeds that find their way through the gravel and into small crevices in the old pavement underneath. The weed is so prolific that it can quickly inundate an area.
It is undesirable to have any weeds in the nesting site or in the immediate vicinity of the nesting site. The historic nesting habitat of the terns is on beaches. The presence of vegetation in close proximity to the nesting area signals possible hiding places for predators and may cause the terns to look elsewhere for safe nesting.
On both days, volunteers included members of the Key Club at Encinal High School in Alameda, a student organization that encourages volunteerism.
Monthly work parties organized by the Friends of the Alameda Wildlife Refuge will continue through March of next year. The terns arrive in April. To get involved, contact FAWR.
