WARBLERS REFUEL AT CITY CREEK
When the yellowest of all warblers - the aptly
named yellow warbler - makes a migratory pit stop at Coyote Creek in
the heart of San Jose it usually gains weight. A long-term
bird-banding program at the Coyote Creek Riparian Station found that
over half of these winged visitors fattened up during their rest and
refueling stop on the long fall flight from North America to Mexico.
"It shows that even the small fragments of
creekside habitat we have left are really important to neotropical
migrants," says the Station's Chris Otahal.
The station placed a series of nets on poles to
trap the yellow warblers - 4-5-inch-long members of a brightly
colored, constantly flitting bird family that one guide calls the "butterflies
of the bird world." The warblers fly into these extremely fine "mist
nests" and fall into a pocket. Station volunteers then weigh,
measure, band and release them for recapture and comparison later.
The program found that many Dendroica petechia used
the site for extended periods during the fall migration (mean of four
days, range 1-13 days). Of these resting birds, 57.9% gained mass,
15.8% maintained mass and 26.3% lost mass, indicating that most birds
used the area for refueling. Fat load changes ranged from a loss of
1.5 grams to a gain of 5 grams (mean gain was 0.5 grams). Such gains
are quite substantial considering the average mass of these birds is
only 10.1 grams. Each gram of increased fat allows an individual bird
to increase its flight range by over 200 kilometers.
Otahal was surprised by the relatively small
amounts of fat put on, compared to eastern migrants.
"Western migrants may have a different
strategy, picking up a little mass and moving on to the next site in
little hops, as opposed to the larger hops and bigger gains of eastern
birds," he says. Otahal speculates that this difference may be
due to the habitat differences, with western migrants having to find
islands of seasonal food and water in a largely dry landscape while
eastern migrants have large, contiguous wooded areas in which to
rejuvenate.
Otahal says more warblers have been visiting Coyote
Creek lately. "The water district's small creek restoration
sitehas brought more birds in," he says. The species is closely
associated with riparian areas, depending on the cottonwood and willow
trees of creek banks for resting and breeding grounds. Farming and
urban development in the warbler's historic creekside breeding grounds
in the Central and Santa Clara Valleys has resulted in a "dramatic
decline" in California breeding populations since the 1930s,
according to Otahal.
But others among the seven neotropical migrant
species banded at the Coyote Creek site were worse off. Most of the
Pacific Slope flycatchers, for example, had used up all their fat
reserves and were starting to burn muscle tissue during their stay at
Coyote Creek. "These birds are so stressed, there's no room for
error," says Otahal. "If this site disappeared, it would be
hard for them to make it any further."

EEL GRASS IN THE OAKLAND HARBOR?
The Port of Oakland is looking for a way to divvy
up the spoils from its planned 50-foot dredging project. And it thinks
it may have found a perfect disposal site, right in its own back yard.
The Port proposes employing approximately 7 million
cubic yards of the dredged materials to establish an eelgrass strewn,
shallow water habitat in a portion of the middle harbor formerly used
by the Navy. If the project gets the go ahead, the Port would not only
create a feeding and roosting area for birds such as the endangered
California least tern, it would also save millions of dollars in
disposal costs.
The Navy dredged the 190-acre basin to a depth of
up to forty feet, and built three finger piers for loading and
unloading its supply ships. According to the Port's Jody Zaitlin,
however, the basin lacks the space necessary to accommodate modern
container ships. "It's not going to be very useful to us."
But then again it might be. The Port will have to
dispose of 12-15 million cubic yards of material to construct the
50-foot-deep channels it so badly wants. Using the middle harbor site
would cost an estimated $7 per cubic yard. Dumping it in deep ocean
waters would cost $17/cy, and barging it to a wetlands restoration
project at the former Hamilton Air Force Base would be $20/cy, says
Zaitlin, adding that those are "very preliminary estimates."
It would take an additional $4 million to turn the basin into habitat,
but that's still far cheaper than the other options.
Zaitlin says the Port is taking advantage of a rare
opportunity to establish a badly needed habitat in the heart of the
industrialized Bay. Most of the basin would still be underwater, even
at low tide, but the depth would be reduced to 2-10 feet, making it
much more productive as a habitat for plants and fish. In addition,
the Port will build a salt marsh and several artificial bird roosting
islands along the shoreline. The project will accommodate humans as
well. People in non-motorized boats will be able to cruise the waters
and there will be a fishing pier, trail and waterfront park where
visitors will be able to observe the avian activity.
Most of the dredge spoils will be relatively clean
Merritt sand, but the Port will have to do more than just dump it in
the basin, Zaitlin adds. It will build a jetty across the entrance to
deflect the wake of passing shops, along with a berm and channels to
help keep the sediment in place. A few eelgrass plants will be put in
place by divers, and will hopefully spread throughout the basin.
The Bay Plan will have to be amended for the
project to move forward. One major issue is whether it's classified as
a "dredge disposal site" or "habitat restoration,"
notes the S.F. Bay Commission's Eric Larson. "There are a lot of
other restoration sites the fill could be used for," he says. The
agency also has questions about the viability of the eelgrass
plantings and the possibility of the dredge spoils drifting back into
the Bay.
David Nesmith of the Sierra Club's Bay Chapter says
his group is "cautiously supportive" of the restoration
project. He credits the Port with "hiring the best people in the
business" to design the habitat (Keith Merkel &Associates),
but he says the "larger question" is whether or not the
fifty foot dredging is worth the potential environmental risk.
Zaitlin is confident any obstacles can be overcome,
and says the Port hopes to start dredging in May of 1999. It will take
several years to complete the restoration, and to the casual human
observer, the subtidal areas won't appear to be all that different.
But, she says, "To the birds and fish, things are going to look
much better."

BULLETIN BOARD
Nine California Plants Listed
Nine "really rare" plants associated with
upland wet spots, seeps and warm springs in California got federally
listed as endangered on October 22, 1997, according to U.S. Fish &
Wildlife's Jan Knight. The plants, many of which inhabit the North Bay
region and seven of which are already state-listed, include Clara
Hunt's milkvetch, white sedge, Sonoma alopecurus, Vine Hill clarkia,
Pitkin Marsh lily, Kenwood Marsh checkerbloom, Calistoga allocarya,
Napa bluegrass, and showy indian clover. Most of them occur only on
private land, says Knight, and thus no federal "take" (loss)
limits can be established for the plants under current law. Indeed
there is "no federal nexus" for the kind of protection
enjoyed by other species under wetland development or levee
maintenance permits, for example, according to Knight. The Service is
currently working on a recovery plan. According to environmental
groups in lawsuits with the Service, the nine plants are among 95
species nationwide and 160 in California that the Service has allowed
to dwindle toward extinction by stalling on final listings.

Greener Oakland Businesses
Abbey Press and 23rd Street Auto Repair recently
received official certification as "green" businesses
through a program run by a partnership of elected officials,
environmental regulators, utility companies and business groups. To be
certified, a business must be in compliance with environmental
protection requirements and also conserve energy, water and other
resources. Businesses that meet the standards get a window decal and
logo to show off to their customers. Abbey has reduced paper waste and
eliminated chemicals from as many printing processes as possible, even
advocating paperless business transactions. The auto repair store
carefully manages hazardous materials and water. "My customers
know that I run a clean, environmentally friendly garage because local
compliance agencies and utilities have been here to verify it,"
says the shop's Andres Herrera. Contact: Pam Evans

Warm Ocean Lures Bass
Scientists recently began exploring the
possibility that the long-term decline in the Estuary's striped bass
population may have been initiated by a 1976-1977 global climate
shift, rather than by low freshwater flows and high exports over the
years. New findings suggest that the shift in global climate produced
frequent periods of warmer ocean temperatures that stimulated
migration to the ocean by many older striped bass. This resulted in a
sharp decline in the abundance of older fish, which subsequently
contributed to the declining recruitment of 3-year-olds in the
Estuary. Although Atlantic striped bass have traditionally migrated
and wandered in the near-shore ocean, the sudden and frequent
reversions to such behavior by this popular introduced sport fish in
California initiated a decline in the Estuary. Contact: Bill

Water Wars Bubble
Virtually all parties to negotiations over the
allocation of 800,000 acre feet of water set aside for fish
restoration by the CVPIA are unhappy with a compromise plan announced
by the Department of the Interior in late November. The plan seeks to
meet the CVPIA's fish restoration goals though a combination of eight
measures, including water releases on the San Joaquin and Sacramento
rivers. "We're very disappointed with Interior's actions,"
says Save the Bay's Barry Nelson, "They have weakened protection
for fish in dry years." Farmers are also displeased: one day
after the plan was announced the San Luis & Delta Mendota
Authority, which represents large agricultural water users, filed suit
in federal court to have it thrown out.
New Habitat Bill on the Hill
Republican John Chaffe of Rhode Island introduced
a new bill this October that would create a national estuarine habitat
program designed to restore a million acres of wetlands across America
by the year 2010. Supporters say Senate bill S1222 has 21 co-sponsors
on all sides of the political debate. Rather than drawing money from
U.S. EPA and competing with the existing National Estuary Program, the
bill seeks $100 million a year from sources such as the U.S. Army
Corps of Engineers. Save the Bay's Barry Nelson says there are lots of
worthy restoration projects in S.F. Bay that might never get a chance
of being funded without it.
Treasure Island Treatment Marsh?
Environmentalists and public trust groups are
proposing that Treasure Island's base clean-up and redevelopment
include creation of a 10-20 acre water treatment wetland on the
island's eastern flank. A new 55-page feasibility report explores
opportunities for building a wetland to treat stormwater before it
enters the Bay. The island was constructed on Bay fill at high cost to
the estuarine environment, so it seems fitting that it now contribute
to a cleaner Bay, say report authors. The proposed wetland could be
constructed in an area that already needs to be excavated to remove
contaminated soil. Project proponents - Arc Ecology, Golden Gate
Audubon, Public Trust Group and Urban Ecology - have been shopping the
proposal around and recently succeeded in getting it into one of the
redevelopment's EIS/EIR options. The environmental impact report is
due by January. Contact: Eve Bach (415)495-1786
REVAMPING VARNALIS
A long-awaited plan to protect salmon in the San
Joaquin River while collecting new data on fish friendly flow-to-export
ratios is nearing completion, according to negotiators. The San Joaquin
has long been a focus of California's water wars, as farmers,
environmentalists and water districts haggle over how much water to
leave in the river for fish and how much to pump for agriculture and
export. Heavy pumping in the past has devastated the river's once
abundant salmon runs.
The Vernalis Adaptive
Management Plan (VAMP) grew out of a lawsuit filed by water users in
1995 against regulatory agencies over exports and spring flows at
Vernalis, a monitoring station downstream of the confluence of the San
Joaquin and its tributaries, the Merced, Tuolumne and Stanislaus Rivers.
The San Joaquin River Group Authority claimed that the flows established
to protect fish by the 1994 Bay-Delta Accord and codified by the 1995
state Water Quality Control Plan were not scientifically justified.
According to the EPA's Patrick Wright, state and federal agencies agreed
to work with water users on an implementation plan for Accord Flows, but
insisted that the resulting plan be "equally protective of salmon
and designed as an experiment to sort out the differential effect of
various factors affecting fish survival."
Under the plan, flows during the mid-April to
mid-May fish migration period would be set at specific levels
depending on the year's water conditions. "For every condition we
will have a set flow-to-export ratio so that we can compare their
effects on salmon survival," says the Bay Institute's Gary
Bobker. By and large, flows under the plan will be comparable to those
established by existing law. The plan also calls for a fish barrier
atthe head of Old River and a "ramping down" mechanism at
the end of the flow period so that fish don't get stranded when flows
are reduced.
Still unresolved is who will provide the water and
money needed to implement the plan. Under the Central Valley Project
Improvement Act (CVPIA), water users on the San Joaquin upstream of
the Friant Dam are temporarily exempt from providing water for
restoration purposes; instead they make a larger contribution to the
CVPIA Restoration Fund. Negotiations now are focusing on the use of
the Fund to compensate water users on the river's tributaries for the
water they provide - a situation that makes environmentalists
uncomfortable. "There's a lot of controversy over using
restoration money to pay water users to meet water quality standards,"
says Bobker. However, environmentalists are considering whether it's
possible as a temporary measure.
Some of the water may come from the 800,000
acre-feet/year of water set aside by the CVPIA for environmental
restoration. In November the Department of the Interior announced
eight measures designed to meet the law's goal of doubling anadromous
fish population in Central Valley rivers. The measures will ensure
that sufficient water will be available to meet the VAMP's target
flows, according to Wright.
Details surrounding export limitations remain to be
hammered out. "We've been working from the premise that there
will be no net loss over the course of the year," says Dan Fults
of the Friant Water Users Authority. "If someone has to cut back
on pumping during the flow period, we want to make sure that they can
make it up." Environmentalists are concerned that a no-net-loss
approach not be used to prevent the use of CVPIA water.
Assuming the remaining issues can be resolved,
negotiators say they hope to start implementing the plan this spring.
The plan is scheduled to last for 12 years. At the end of that time,
says Bobker, "the hope is that we will have enough data to allow
us to revisit some of these issues," such as assessment of
responsibility for water contributions and funding.
In the meantime, says Dave Fullerton of the Natural
Heritage Institute, "the agreement is important as a precedent.
It shows how you can set up a management system to be protective, and
maximize the opportunity to increase scientific understanding."

RICE HABITAT SWELLS
There's seven times as much flooded rice field
habitat for ducks to feed and frolic in that there was four years ago.
The California Ricelands Habitat Partnership now boasts at least
150,000 acres of rice fields winter-flooded for wildlife in the
Sacramento Valley. "If you count the marshlands on private duck
clubs and state and federal refuges, the total is probably over
200,000 acres," says Mike Bias of Ducks Unlimited, one of the
organizations in the partnership, which began as a 20,000-acre pilot
project in the winter of 1993.
After a state law was passed restricting rice
burning, the partnership formed to test whether flooding post-harvest
fields could effectively decompose rice "straw" while
offering winter habitat for migrating waterfowl. So far, the project
has met with success, both in decomposing straw and offering habitat
for large numbers of ducks. "We're proud of what we've
accomplished," says Steve Butler, a grower and duck hunter. "We
went from an all-time low in the late 1980s to the large numbers of
birds we see out here now." Estimates of the number of ducks
using the ricelands range from 2-4 million.
Although there's more waterfowl habitat and cleaner
air in the valley, some hunters have begun to complain they aren't
seeing as many ducks. Wildlife managers explain that when more ducks
are crowded into less space, the hunting is easier, and some hunters
feel more successful. Other hunters feel that crowding too many birds
into less habitat is unethical. The worry is that if you make things
too good for ducks by dispersing them over large areas, hunters will
stop spending money on managed wetlands. At least 70% of California's
marshland is owned and managed by duck hunters.
Cal Fish & Game's Glenn Rollins says that duck
hunters not only pay dearly for blinds and licenses, but often pay
more for water to flood their wetlands. Farmers who flood and operate
duck clubs on their fields pay more than farmers who flood just to
provide habitat. "We've got eight species of ducks supporting
over 200 species of birds out here," he says.
In an effort to get a better distribution of ducks
throughout the valley, Rollins is working with farmers elsewhere to
teach them how to establish hunting programs. He feels there is
probably some optimal amount of habitat that will support the maximum
amount of ducks possible and still allow for good hunting. But other
factors affect duck numbers too. If breeding habitat in the north is
dwindling or isn't good quality, for example, just creating more
winter habitat won't increase bird numbers.
In the meantime, the flooded rice fields are
providing benefits for more than just the waterfowl sought by hunters.
"You've got all kinds of shorebirds wintering here, western
sandpipers, killdeer, avocets," says Rollins. "Plus wading
birds, ibis, egrets, herons, even gulls. You see them standing out
there eating crayfish." Counts of shorebirds in the Sacramento
Valley last winter numbered in the hundreds of thousands. Rollins
would like to see farmers manage their wetlands for these birds too.
Although most ducks prefer depths of at least a foot (or deeper),
shorebirds prefer shallower water. "You'll often see them around
the edges of the fields," he explains.
Despite the concerns of a growing number of
hunters, most people agree that the Ricelands Partnership is a good
thing, allowing agricultural land to remain productive while providing
much-needed habitat. Some wonder what will happen in drought years,
when every drop of water is needed for fish flows, or when the market
for rice straw (for alternative energy, erosion control, etc.) takes
off and growers can make more money from selling their straw than
flooding it. But in the meantime, a new and possibly bigger threat to
ricelands has emerged. "You're starting to see cotton in the
Sacramento Valley," says Mike Bias. More cotton fields mean less
rice habitat and more problems for rice growers (cotton is sensitive
to the herbicides used on rice). As Mike Miller of the Central Valley
Habitat Joint Venture Technical Committee puts it, "There's a
saying that rice IS wildlife habitat. Without it, you're never going
to support all these birds." Contact: Mike Bias

OUR LADY OF THE CREEKS
Carole Schemmerling arrives at the Urban Creeks
Council office breathless and disheveled after a morning spent
baby-sitting her ten-month old granddaughter, mediating a neighborhood
tree dispute, and rescuing some trampled ferns on Blackberry Creek.
She frowns at the pile of telephone messages awaiting her from friends
of creeks groups, teachers, students of all ages and local politicians
- all seeking advice. But Schemmerling can't say no when it comes to
creeks.
Schemmerling has served as Bay Area coordinator of
the Urban Creeks Council for the past three years and as council
president for twelve years before that. She was also a member of
Berkeley's Parks Commission for over a decade. When Schemmerling first
suggested to the Parks Commission that they dig up long-buried creeks
and bring them back above ground "They just stared at me blankly,"
she says. But she and other creek advocates, including landscape
architect Doug Wolfe, persevered and in 1985 they helped resurface an
underground stretch of Strawberry Creek in the Berkeley flatlands and
convert an adjacent former blighted railroad right-of-way into a
charming neighborhood park named after the creek.
How does one become obsessed with creeks? "I
grew up in the slums of Philadelphia," explains Schemmerling. "But
my grandfather would take us to this beautiful clear stream,
Wissahicken Creek, a tributary of the Schuykill River. The creek was
an oasis to me, a haven," she says. Later, Schemmerling saw
Appalachian streams bright orange with runoff from steel mills, and
when her family moved to Cleveland near the Cuayahoga River ("you
know, the one that caught on fire"), she realized not everyone
shared her values about creeks.
When she moved to the Bay Area, Schemmerling became
fascinated by the snippets of streams that still flowed openly
throughout the East Bay. "I wanted to get them out of those
pipes," she says. After the Strawberry Creek success,
Schemmerling went on to champion the opening up a stretch of
Codornices Creek. And later when the park at Thousand Oaks School
needed renovation, she convinced the city to dig up the section of
Blackberry Creek below.
During the "down time" between creek
uncoverings, Schemmerling was busy behind the scenes. "She had
this impatience to do something," says Ecocity creator Richard
Register. "She thought that if we couldn't uncover creeks, we
could at least call attention to them." Schemmerling's suggestion
of painting blue creek "stripes" across streets beneath
which creeks were buried evolved into the salamanders, snakes and
other "creek critters" Register designed as stencils for
Berkeley storm drains.
Which Berkeley creeks does Schemmerling hope to
uncover next? The ultimate "urban" creeks: a branch of Derby
Creek that flows beneath People's Park, and the section of Strawberry
Creek that flows between the UC campus and downtown Berkeley.
If anyone can unearth these two creek stretches, it
will be Carole Schemmerling, says Ann Riley of the Waterways
Restoration Institute - Schemmerling's long-time friend. "Carole
has this knack for pulling in different kinds of people,
neighborhoods, and community groups and organizing them around creeks
to better their neighborhoods," says Riley. When tempers in El
Cerrito flared last summer over a creek restoration that city had
undertaken, the diplomatic Schemmerling allayed the fears of angry
residents by showing them slides of other restoration projects and
talking to them about what the creek would eventually look like.
Beneath Schemmerling's easy-going exterior lies the
passion of a true conservationist. "There are places I'll never
see, places I'll never go to," says Schemmerling. "But I
want to know that they're there." Meanwhile, she focuses on doing
what she can, here and now. "I have no illusion we can return
things to the way they once were," she explains. "But to me
anything that begins to resemble the way things were naturally is so
much more interesting." Recently, a fellow creek-restorationist
told Schemmerling he'd seen a 16-inch steelhead in the lower reaches
of Codornices Creek. Although fish haven't migrated all the way up
Codornices for years, just knowing they're testing the waters is
enough for Schemmerling for now. "That pleases me no end,"
she sighs.
WETLAND-FRIENDLY FARMING IN THE
NORTH BAY
Green velvet on duck heads; sunlight on grape
leaves; hay waves, dozing dairy herds, long grasses tossed by Bay
waters - these are all images from a new film on the San Pablo
Baylands. The film premiered this October before a crowd of 250 local
citizens, decisionmakers and press, marking the passing of another
milestone in Save the Bay's partnership program to promote wetland and
wildlife-friendly stewardship of the Bay's four-county, 50,000-acre
northern fringe.
"The film paints a picture of a land nobody
knows about, the Bay Area's last, vast expanse of open space, wildlife
habitat and agriculture," says the S.F. Bay Commission's Jeff
Blanchfield, whose agency is spearheading another of the four major
wetland protection programs that have zeroed in on the North Bay in
recent years. "It's absolutely wonderful, we've already shown it
to our commissioners," he says.
Accompanying the film is a 12-page overview of the
history and value of the San Pablo Baylands, and of options for
protecting both its family farms and natural resources. This overview,
and the more detailed forthcoming report it previews, is the product
of 18 months of workshops and steering committee meetings with
landowners from the region, ranging from individual farmers to state
and federal agencies that own and manage area wildlife refuges.
According to Save the Bay's Marc Holmes, his Partnership for San Pablo
Baylands is different from the North Bay's other wetland-targeted
efforts because it has acknowledged the need to protect agriculture,
as well as wetlands, from the get go, and because it is working with
landowners outside the regulatory arena to make them "the guiding
body" for future protection efforts.
"So much is coming down here so fast we don't
know who to trust," says farmer Norm Yenni. "Save the Bay's
doing the best job it can without a regulatory approach."
Holmes points out that more than half of San Pablo
Bay's diked wetlands are unprotected and vulnerable to development,
particularly along the Highway 101 corridor where cities like Novato
have a "disinclination" to preserve them. Imminent threats
include a proposed doubling in size of the Bel Marin Keyes lagoon
community, and a planned 18-hole golf course at Black Point. But no
one's going to accept the same kind of government intervention used to
create the South Bay's large refuges and the Suisun Marsh protection
plan, says Holmes, nor are public dollars available in the
astronomical amounts needed to replicate that approach today in the
North Bay.
"We can't purchase or regulate urbanization
out of the area," says Holmes. "Our best hope is sound
stewardship by the landowners themselves."
According to the plan overview, such stewardship
may take the form of voluntary best management practices by farmers
such as vineyard cover crops to prevent erosion, integrated pest
management to minimize chemical runoff, bird boxes to shelter
songbirds, deer fences allowing mammal migration, composting to
enhance soil fertility, and or conservation easements, tax incentives
and management agreements that promote on-farm wetland protection.
One best management approach that would greatly
benefit wildlife would be a shift from winter to summer cropping. "If
farmers could switch from dry farming to irrigation they could grow
summer crops, freeing up land to operate as seasonal wetlands in
winter," says Holmes. What crops, water sources and fertilizers
could be used for such changes are things Holmes hopes to see
researched on a model farm proposed as part of the stewardship
program.
"I'd like to know if we can get the soil right
to grow grapes or asparagus on tidelands - asparagus is pretty good
money," says Yenni. "An experimental farm could help answer
these questions."
So farmers like Yenni don't have to shoulder the
risks of experimenting, Save the Bay is proposing the model farm be
located on public lands. Skaggs Island, proposed for acquisition by
U.S. Fish and Wildlife, is one possible location. According to Fish &
Wildlife's Betsy Radtke, her agency can use a special use permit to
allow farmers to develop farming techniques on the island that are
both beneficial to wildlife and specific to the unique conditions of
the North Bay - "techniques they can then take home and use on
their home farms," she says. "It would be a good use of this
property until it can be restored to wildlife habitat."
The model farm, education programs (see Canoeing
the Sloughs), and a new organization and clearinghouse for stewardship
efforts are the centerpieces of Save the Bay's program - now being
considered for CALFED funding. Despite a worthy vision and excellent
film, the real long-term benefits and products of the $500,000 program
remain unclear.
But the farmers and landowners are still at the
table, points out Radtke, who serves on the partnership's steering
committee. "We still haven't gotten to implementation, and that's
the big test," she says.
Landowners like Yenni are worried that no matter
how good the stewardship efforts are, regulators such as the Bay
Commission will eventually take over. But the Commission's Blanchfield
insists his agency has no such authority. Meanwhile other landowners
worry that even a stewardship approach is too limiting. "We don't
want to be locked into farming for eternity," says rancher Jim
Haire.
"The good thing about the plan is it's a tool
box - you can pick and chose what to use," says Yenni. "I
think you'll see some people using it in time. Politically, we're
going to have to in order to get by."

CANOEING THE SLOUGHS
Many of the sloughs that riddle the edges of the
Bay look like little more than ditches. But a new Save the Bay program
is giving middle and high schools students an up close-and-personal
view of these channels and their ecological importance.
Canoes in Sloughs teaches participants about
canoeing and then takes them into the sloughs for a day of bird and
plant observation, water testing, and pollution-source identification.
"Canoes let you go places you wouldn't ordinarily see," says
Save the Bay's Amy Windrope. "With this program, the kids get to
see that there's really lots of wildlife right in their own backyards."
"It was an incredible opportunity to get
students out on the water and show them in the real world what we are
learning in the classroom," says Redwood High School teacher Joe
Stewart, who recently took all three of his freshman/sophomore
integrated science classes through the program. "It's a unique
program because we start by talking about the issues confronting the
Bay and then go into the science of it, instead of the other way
around," says Windrope.
So far this fall approximately 800 students have
participated in the program, which was launched last spring with a
grant and technical assistance from the Chesapeake Bay Foundation. The
Toyota Corporation recently awarded the Foundation a grant to export
its 30-year-old Chesapeake canoeing program to other areas. In
addition to the student program, Canoes in Sloughs has also held two
one-week programs for teachers, "focusing on the Bay as a
teaching tool and a resource management dilemma," says Windrope.
Windrope says that one of the best things about her
program is that it is completely mobile. "There are sloughs all
over the Bay," she says. "Recently we put the canoes in the
water just a few hundred yards from the back of a school," she
says. Most excursions so far have focused on the North Bay, but
eventually Windrope says she hopes to include not only the entire Bay
Area, but also upstream rivers as well. "We want to show everyone
in this watershed that they are connected to the Bay," she says.

WILSON SCRAPS BAY PROTECTION
PROGRAM
With a stroke of the pen, Governor Wilson has sent
the state's Regional Boards scrambling to complete clean-up plans for
toxic hot spots in San Francisco and other California bays by the end
of the year - long before needed studies of these sites are complete.
In October Wilson vetoed legislation that would
have continued funding for the Bay Protection Toxic Cleanup Program,
created in 1990 to identify, evaluate and monitor toxics in water,
sediment and Bay-caught fish. The program had been supported by fees
paid by municipal and industrial dischargers. Wilson also directed the
Regional Boards to carry out the existing law, which requires that
clean-up plans be delivered to the State Board by January 1st.
"This was never anticipated," says the
S.F. Regional Board's Karen Taberski, noting that a 1995
implementation plan produced by the State Board directed the Regional
Boards to focus on data collection and monitoring rather than
developing clean-up plans through the end of 1997. Indeed, Taberski is
just finishing up a painstaking three-year effort to develop
scientifically sound toxicity testing protocols and reference sites.
She has screened 150 suspected toxic hot spots using the new methods.
Taberski says that under standard procedures, once
a contaminated site is identified, additional studies are conducted to
determine the aerial extent of the contamination and clean-up
feasibility - a process that can take an additional three to 10 years.
Only after these studies are complete would a clean-up plan be
developed. "We've been given just ten weeks," says Taberski.
In his veto letter, the governor criticized the
program's approach to human health risk assessments - a claim that
Save the Bay's Keith Nakatani dismisses as "completely
insupportable." Nakatani says he believes that the reason for the
veto was that "this legislation would have put teeth in the
program and forced big dischargers to do some real cleanup." M'K
Veloz of the Northern California Marina Association says her members "fully
support the governor's logic."
As a result of the accelerated time-frame, Taberski
says the clean-up plans will consist primarily of options such as
capping or dredging contaminated sites. Where responsible parties can
be identified, the Regional Board will require them to conduct aerial
extent and feasibility studies, and develop clean-up plans themselves.
According to the State Board's Gita Kapahi "the
plans that the Regional Boards provide at the end of the year will be
proposed plans that will satisfy the law, but they will not be
considered complete until the State Board adopts them." The Board
has until June 1999 to develop a final clean-up plan for the entire
state. In the meantime, additional data that has already been gathered
will be analyzed and incorporated in the plans. The governor has
ordered the State Board to draw up a budget proposal to keep the
program afloat for the next year and complete the clean-up plans,
although precisely where these funds might come from is still unknown.
"The law is specific about what the plans must
include and these plans are going to have big holes in them,"
says Save the Bay's Nakatani. "We are skeptical that they will be
able to fill those holes in one year."

HUMANS AND CANINES BEDEVIL BEACH
BIRD
Snowy plovers made headlines recently when
dog-owners at San Francisco's Ocean Beach bitterly protested the
enforcement of leash laws to protect the sparrow-sized birds. But the
real action has been behind the scenes, where the National Park
Service, U.S. Fish & Wildlife and others have been quietly working
to craft long-term plans to help the waning beach bird.
In 1993 Fish & Wildlife listed the coastal
population of the Western snowy plover as a threatened species. Much
of the bird's decline is due to loss of habitat, as well as habits
that make it susceptible to predators and careless humans. Plovers
like to nest in shallow depressions on sparsely vegetated stretches of
beach. Because the sand-colored birds blend into their surroundings,
walkers, joggers, dogs, horseback riders and vehicles can
inadvertently crush nests or drive off adult birds, leaving the eggs
and chicks to die of exposure or predation. The plover's nesting
season runs from mid-March through mid-September, which coincides with
the heaviest human beach use. "You can definitely see why they've
become a threatened species," says Fish & Wildlife's Dan
Burford.
Early in 1998, the Park Service expects to release
a plover management plan for Ocean Beach that addresses the full range
of factors affecting plovers and their habitat, with a particular
focus on sand management and recreational beach use.
"Ocean Beach is just one piece of the picture,
but if you don't have that piece the entire picture falls apart - each
site is important for recovery," says Fish & Wildlife's Ruth
Pratt. Just 28 plover nesting areas remain in California, Oregon and
Washington. Plovers are remarkably consistent, according the Park
Service's Daphne Hatch, who says she has seen banded birds return year
after year not only to the same roosting area, "but also to the
same part of the beach, where they hang out with the same crowd of
birds."
Plovers nest at several locations around the Bay,
including the salt ponds of the South Bay. The Hayward Area Recreation
District recently acquired 155 acres of the former Oliver Brothers
salt ponds near Highway 92, which it plans to manage for plover
habitat.
Fish & Wildlife is currently developing a
recovery plan covering the entire West Coast, and Pratt says she hopes
to complete a preliminary draft next summer. The plan will include
specific range wide management actions designed to protect the plover.
However, according to Pratt, one of the most important parts of the
plan will be a massive public education effort to raise awareness
among beachgoers and others about the tiny birds underfoot.
