Dirt Biking Concerns Conservancy Group

Reprinted with permission of SouthSanFranciscoPatch

San Bruno Mountain Watch members investigated dirt bike tracks behind Terrabay neighborhood on Monday morning.

 

Walking through the Terrabay neighborhood Monday morning, three San Bruno Mountain Watch members looked for clues to where a dirt biker is entering the park.

South San Francisco residents Loretta Brooks, Chuck Heimstadt and Ken Oborn, all members of a San Bruno Mountain Watch conservancy committee, noticed the illegal tracks a week ago.

Brooks says dirt biking can destroy lupine, a primary food source for the endangered Mission Blue Butterfly, which is native to the mountain.

"We are trying to find a way to protect open space around here," Brooks said.

The group suspects that the dirt biker entered the park at the end of Highcrest Lane, off of Hillside Boulevard, where there is parking and easy access. A sign clearly marks that motorized bikes are prohibited in the park.

The sun peaked out from behind the clouds as water trickled down the verdant canyon and ravens circled overhead.

While hiking up the steep ascent, Brooks and Heimstadt pointed out a variety of invasive species, like fennel, radish and Italian thistle.

"The whole food chain is interconnected," Heimstadt said. "By bringing in the non-natives, it breaks up that food chain."

Native species like Blue-Eyed Grass, Sticky Monkey, and California Aster also sprout along the trail, but in fewer numbers.

The group wants to help the San Mateo County Parks Department weed out invasive species in the area but is waiting on a permit.

Heimstadt said there are multiple paths leading up the mountain, but all of them are steep.

"This was never a built trail," he said. "It needs to be switch backed."

The couple looks forward to a proposed east-west bike trail that would go from Oyster Point Marina to the ocean at Fort Funston. A new trail would be built from the base of San Bruno Mountain at Sister Cities Boulevard up to the Ridge Trail.

Hiking up the spine of the canyon past the blooming yellow petals of San Francisco Wallflower, the bike tracks became visible. The tracks zigzag on the mountainside between some rock outcroppings.

Two hikers made their way down, and Brooks asked if they've heard any bikes.

"It's against the law and it can ruin the habitat," she said. The hikers said they haven't seen anyone riding here but will contact authorities if they do.

"There's enough erosion on this mountain without [dirt biking]," Heimstadt says, " and then it's unsightly."

He says the county may be able to install a gate that would stop dirt bikers from entering.

Elias Frangos, park aide for the parks department, said he hadn't received any reports of dirt biking but they will look into it.

"We can definitely go check it out and keep an eye over there," Frangos said.

Chuang Tzu and the Butterfly

Chuang Tzu in dream became a butterfly,
And the butterfly became Chuang Tzu at waking.
Which was the real--the butterfly or the man?
Who can tell the end of the endless changes of things?
The water that flows into the depth of the distant sea
Returns anon to the shallows of a transparent stream.
The man, raising melons outside the green gate of the city,
Was once the Prince of the East Hill.
So must rank and riches vanish.
You know it, still you toil and toil--what for?
--Li Po

The world around us is aquiver on the Summit Loop Trail, the dusty 3.1-mile footpath that climbs through the chaparral, coastal scrub, oak woodland, and riparian habitats that cover San Bruno Mountain. I'm told that winds up here often reach 30 miles an hour, just shy of gale force. At around 1,300 feet this spot on the ridgeline at the northern end of San Mateo County looks out over most of the hyper-developed bay-centered core of the Bay Area. My hiking companion and I gaze northeast to the chalk-colored crenellated sprawl of San Francisco and southwest to suburbia and the cemeteries of Colma. We can just make out the traffic along the roads and freeways that crisscross the landscape below, but we can't hear it. "It's so quiet up here," I whisper. The leaves around us, shaking like minuscule flags, let loose a febrile rustle. The only other sounds are the whoosh of warm wind under my hat brim, the crunch of rock beneath our boots.

It might seem deserted, but it isn't. San Bruno Mountain State and County Park is densely populated, not with humans but with a vast array of wildlife, including a number of rare and imperiled plant species. I come here for the butterflies, to check up on a habitat essential to their existence, though I don't expect to see them flying around at this time of year, early fall. They should be well hidden as tightly wound pupae, sequestered beneath the carpet of vegetable litter that blankets the hillside, overwintering in dreamy diapause, dormant until spring. This is one of the last places on the planet where, if you know where and when to look and what to look for, you can see San Bruno elfin, Mission blue, and Callippe silverspot butterflies--all listed as endangered species, which is a terrible distinction as it is the last step before the end of the evolutionary road. The endangered bay checkerspot, too, once called the mountain home, but it has not been seen here in over a quarter century.

These are not large butterflies; they are small and discreet, certainly not flamboyant in the manner of monarchs and swallowtails, but still exquisite in color and design. Even so, it is not my intention to actually see them. I like that they are hidden, safe from harm in their pupal slumber. And, in any case, I have always been far more interested in the earlier, seemingly more durable stages of these insects' development. The adults in their mature imago form have always been ghosts to me; their fleeting presence, while beautiful, signals little more than doom. They represent a dilemma, a dangerous beauty, the alluring specter of transience; they mean hope for their kind in the ever-unfolding drama of life, but for the individual butterfly, nothing but death.

As a child I saw them as something fragile that, once caught, rarely lasted. When I was six, a small girl in England in a country landscape that was rich in flora and fauna, I filled glass jars with the interesting little creatures that slithered and crawled in the fields around my home. I collected creepy things: snails, slugs, beetles, spiders, and beautifully colored, magnificently furred caterpillars that I

liked to believe were patiently feeding on the blades of grass (in most cases a totally inappropriate food source) with which I had imprisoned them, unintentionally consigning them to an early death. Sometimes my captives were prettier and more active: ladybugs, honeybees, and the occasional unfortunate butterfly. The butterflies were quick to expire, their swift demise eventually reenacted by the other members of my glassed menagerie. Later, in the wild landscapes of northern Japan when I saw uniformed schoolchildren scouring the meadows with white butterfly nets, it would strike me that their enthusiasm was nothing more than a deadly innocence, the one perfect image of summer in a season that passed far too quickly, that was always too short.

I learned the facts about butterflies in high school: that they are members of the phylum Arthropoda; the class Insecta; the order Lepidoptera; and that in the course of their short lives they undergo metamorphosis through four stages--egg, larva, pupa, and adult. I remembered crying years before when one of the lovely caterpillars I'd gathered "died." It turned brown, shapeless, and still as a corpse, nestled in the greenery with which I'd stuffed its jar. Saddened, I threw the whole mess out. It wasn't until I saw a photograph years later of the next phase of a caterpillar's life that I realized my once-wriggling prisoner had simply entered another phase of its existence, not its last . . . that is, until I threw it out in ignorance. I wept all over again.

Here on San Bruno Mountain the butterflies' precarious hold on existence transcends the lives and deaths of the individual insects in each species. Parts of the mountain are currently protected, but the tenuousness of that preservation is written in the development encroaching from below. This 2,300-plus-acre patch of public land is surrounded by houses and subdivisions and has long been the focus of battles between developers and environmentalists. Inside the park another kind of intrusion threatens. Invasive species--eucalyptus, gorse, ivy, broom, fennel, cotoneaster, blackberry bramble--proliferate. The plants upon which the threatened butterflies feed compete with these hardy nonnatives for space.

On our slow ramble up and down the mountainside I contemplate all of this, and I feel a rising sense of pessimism. "If I were to write a butterfly song right now," I say, "it would be a lament, maybe even a dirge." I try to pick out the flora that constitutes the insects' specialized food sources: violets, stonecrop, native plantain, perennial lupines. What I see most are the transplants: ivy, fennel, and blackberries, blackberries everywhere. These plants, like humans, are opportunistic. They muscle out the less flexible species, devouring the natives' space.

That's when I see them. One, two, three--they are careening on winds so rough that I think their tiny bodies should be torn apart. Their appearance seems almost impossible and absurd to me, what with the fierce gusts and the lateness of the season, though adult butterflies can actually live for months. "Look," I say, my spirits lifting ridiculously even though I see the butterflies' erratic dance on the gales as nothing more than a frenetic totentanz.

The smallest of the three finds a sunny resting spot on the rocky path a few feet ahead of us. It flattens its wings, which tremble only slightly as I sneak up to take a closer look. I believe I recognize the markings. It's a checkerspot, but probably not the endangered bay checkerspot, which hasn't been seen here on San Bruno Mountain since the early 1980s. It's almost certainly the much more common cousin, the Chalcedon checkerspot. Still, for a moment, I feel the irrational joy again, to have found these persistent though delicate insects on this windswept hillside. And then the blast of sorrow that generally accompanies this joy--the realization that even as I observe it, the butterfly's life is ending, that the things I cherish--this parkland, the imperiled plants and animals that inhabit it--are in constant and unassailable jeopardy.

I am too close. The butterfly reacts, takes flight, another flitting bit of nature, blindly celebrating the expendability of forms. It's hard to resist that reckless dance and, for an instant only, I slip into its trance; and finally, blessedly, there is only this: the butterfly, the wind, the moment.

San Bruno Mountain Development OK'd after Legal Battle

By Shaun Bishop

August 29, 2010

It appears the endangered callippe silverspot butterfly is going to get some new neighbors on San Bruno Mountain.

A San Mateo County judge’s ruling will allow a 71-home subdivision of a decades-old development plan to go forward, despite the protests of a local environmental group that says the new houses proposed by Brookfield Homes will harm the butterfly.

San Bruno Mountain Watch, which sued to require the developer to conduct a full environmental impact report, is “in conversations with our board and with our attorneys about whether it makes sense to file an appeal,” Executive Director Ken McIntire said. The group has until early October to decide.

“She didn’t address any of our main arguments,” McIntire said of Judge Marie Weiner. “Justice isn’t the same, necessarily, as the truth, especially in environmental issues, because the environment is so complex and judges are not trained as biologists.”

Developer Brookfield Homes did not return several calls seeking comment. The county counsel’s office also could not be reached for comment.

At issue is a plot of land on the Northeast Ridge of the mountain that the county approved for development in 1989, following a 1982 habitat conservation plan that set aside 2,800 acres of the 3,300-acre mountain for conserved habitat.

After the callippe silverspot butterfly was listed as an endangered species in 1997, the original plans for151 homes on 40 acres were later reduced to less than half that number of homes on 20 acres, with the rest conserved as habitat. The developer is also required to create a $4 million fund for habitat management.

County supervisors approved a final revision of the plan in 2009, triggering San Bruno Mountain Watch to sue the county to force an environmental impact report of the development.

Weiner also said a 2007 modification to the plan “deletes dozens of houses from the development to foster greater freedom of the callippe silverspot to travel and protect its host plants.” She also pointed out that the U.S. Fish and Wildlife Service found that the mitigations would result in “no significant impact” to the butterfly.

On the mountain San Bruno Mountain has 14 species of rare or endangered plants along with several endangered or threatened butterflies, including:

Butterflies -San Bruno elfin -Mission blue -Callippe silverspot -Bay checkerspot

Plants: -Coast Rock Cress -Montara manzanita -Pacifica manzanita -San Bruno mountain -Franciscan wallflower - San Francisco owl’s clover  -San Francisco campion

Judge turns away 21-year attempt to stop San Bruno Mountain development

Judge turns away 21-year attempt to stop San Bruno Mountain development

BRISBANE -- A San Mateo County judge has cleared the way for a 71-home subdivision to be built after more than two decades of controversy on a mountain ridge environmentalists say is prime habitat for the endangered callippe silverspot butterfly.

Earlier this month, San Bruno Mountain Watch lost its bid to have a San Mateo County Superior Court judge stop the development by Brookfield Bay Area Builders, Inc. and order the county to prepare an environmental impact report for the project.

The luxury homes, destined for 20 acres on the Northeast Ridge of San Bruno Mountain, have been under intense scrutiny by local and regional environmental groups since they were proposed in 1989. Since then, the size of the subdivision has been whittled down to less than half the number of homes originally slated for the site, largely due to the controversy surrounding the potential loss of butterfly habitat.

Ken McIntire, executive director of San Bruno Mountain Watch, said his group has not yet decided whether to appeal the decision. "We were really disappointed. We didn't feel like anything we were talking about was really addressed," McIntire said.

The callippe silverspot has been listed as an endangered species since 1997, eight years after the county approved a major subdivision on the Northeast Ridge. McIntire's group has long argued that the homes and the six-lane road on San Bruno Mountain that were built since the 1980s have already taken their toll on the butterfly's ability to migrate over the mountain. They contend that this project deserves an environmental impact report to document potential threats to the remaining butterflies.

The group sued not only Brookfield, but the San Mateo County Parks Department and the Board of Supervisors as well, for permitting the project.

"It wasn't enough for us to have witnesses that say they may be harmed," McIntire said. "You have to have witnesses that prove the butterflies will be harmed, which we could not do. If we knew that was the standard of proof going in, we would not have filed a petition."

The county counsel's office did not return calls seeking comment. Nor did a representative of Brookfield.

Judge Marie Weiner's decision offered highly technical arguments for why the latest phase of the subdivision did not count as a separate project from the master plan the county approved in 1982.

She did not address the question of whether it would affect the butterfly population on the Northeast Ridge, other than to note that according to the U.S. Fish and Wildlife Service, the project is "not likely to jeopardize the continued existence" of the callippe silverspot and other butterflies on the mountain. Environmental groups have questioned the science behind that assertion.

The callippe silverspot population crash is attributed to the loss of their host plant, the Johnny jump-up. The project site hosts the most concentrated population of callippes on the mountain but not the largest one. The rest live on the Southeast Ridge in a protected grasslands area.

Brookfield is unlikely to begin construction until next spring, after the rainy season ends. The developer has not applied for a building permit, said Brisbane Senior Planner Tim Tune. Brookfield seems to never have doubted the outcome of its application. All 71 homes in the future community, dubbed Landmark, have already been sold.

Brisbane approves San Bruno Mountain development, outraging butterfly supporters

Brisbane approves San Bruno Mountain development, outraging butterfly supporters

By Julia Scott

Posted: 02/17/2010 07:32:37 PM PST Updated: 02/17/2010 08:31:26 PM PST

BRISBANE — The City Council voted unanimously Tuesday to allow a developer to build a new neighborhood in the midst of prime habitat for the endangered callippe silverspot butterfly on San Bruno Mountain.

The controversial vote capped off three emotionally charged public hearings on the issue and left two women from Brisbane sobbing in the audience. Moments before the vote, a man disrupted the proceedings by standing up and walking toward the council with a thick binder in his hand, his finger jabbing at a page.

"You're making a mistake!" he cried, lifting the binder above his head as police removed him from the meeting.

The debate over the 80 homes destined for the mountain's Northeast Ridge was framed by opponents as a life-or-death decision — for the endangered butterflies, who survive today only on sequestered parts of the mountain, for the environment, and for the soul of Brisbane.

"If the callippe silverspot vanishes, all levels of government will be at fault," declared David Schooley, co-founder of San Bruno Mountain Watch, a Brisbane group that may decide to sue the city and the county for allowing the project to go forward. The group bombarded the City Council with an intense letter-writing campaign and collected hundreds of signatures on a petition. They urged the council to deny the development and order a new environmental impact report that would contain more accurate, updated information about the callippe's whereabouts and ability to breed despite obstacles such as homes and roadways. The last environmental review was conducted in 1983 and may not account for the effects of development that have taken place since then.

To a certain extent, the council's hands were tied by the fact that a 579-unit development was approved for this part of the Northeast Ridge back in 1989. Many of those homes have been built, although this particular subdivision faltered when the U.S. Fish and Wildlife Service listed the callippe silverspot as an endangered species in 1997. The callippe, one of several sensitive butterfly species on San Bruno Mountain, relies on native plants that grow along the project site.

The Fish and Wildlife Service approached developer Brookfield Homes about reducing the building footprint, and Brookfield agreed to cut the subdivision down from more than 108 units to 80 units. Brookfield also agreed to sign over its development rights to Callippe Hill, a nearby 20-acre site that hosts an even richer population of the butterflies. The land will be protected by the county.

Finally, the developer offered a $4 million endowment to strengthen the county's Habitat Conservation Plan, a management tool that funds county efforts to remove invasive plant species such as coastal scrub that crowd out the plants used by the butterflies throughout San Bruno Mountain. About 1,250 acres of native grasslands remain, down from 1,800 acres in the 1930s. About 5 acres of grasslands disappear each year, biologists say.

Brookfield also offered Brisbane $1.8 million to pay for city services and projects, including a new library.

"If we requested a new EIR, the developer would do the 1989 project. To me, I don't see that as an option," said Brisbane Mayor W. Clarke ¿Conway. "I think it's the better project. I know a lot of people will disagree with me."

The Fish and Wildlife Service gave its stamp of approval to the revised project in May, saying that it would not cause irreparable harm to the callippe silverspot based on the agency's review of biological studies. That set the stage for an unusual situation in which environmentalists lined up against an unprecedented opportunity to restore San Bruno Mountain at the expense of losing some butterfly habitat.

Meanwhile, many speakers who opposed the project accused the Fish and Wildlife Service of being a shill for development and sacrificing an endangered species for money.

Cay Goude, assistant field supervisor in the agency's Sacramento office, denied the charges.

"We would not have issued this permit if we did not think it was the best mechanism for the long-term survival of the butterfly on San Bruno Mountain," Goude said. "Without funding of that site, I don't think it would persist over time."
