The mouth of the Elkhorn Slough has long been known for its natural salt ponds. In the late 1800s these areas were developed to produce salt for local use. In 1916, the Monterey Bay Salt Company diked parts of the slough to create commercial salt ponds – a series of ponds where saltwater evaporates in the sun, leaving salt for harvest.

From 1902 until the local fish cannery business collapsed in the mid-1950s, the salt was used to preserve the fish. Later, the salt was used for water softening, refrigeration, and making ice cream. The company continued salt production until 1973. For a short time, the ponds were used to produce brine shrimp.

Today, the Moss Landing Wildlife Area comprises 872 acres that help protect the brown pelican, which was previously listed as an endangered species. Both brown and white pelicans use the ponds along with thousands of small shorebirds. The area is managed by the California Department of Fish and Wildlife.

The salt ponds are home to many birds, including American avocets and black-necked stilts. The threatened snowy plover also uses the salt ponds as nesting grounds and has recently become the focus of management for this area.

SS Palo Alto: War Ship, Night Club, Seal Hang Out, and Modern Art Hotspot

Ranger Gaudinski — Wed, 19 Oct 2016 20:00:48 +0000

The S.S. Palo Alto is a curious oddity with a rich history. It has also become an inspiration to artists who use it to inspire environmental awareness and promote ocean sustainability through the arts. Social Practice Arts Research Center at UCSC is sponsoring the “S.S. Palo Alto Project” which uses the ship as a “thought hub” around which to host art-based projects and events to teach ocean education and inspire environmental awareness.

Depiction of the S.S. Palo Alto by a UCSC art student.

Richard Desanto, who is coordinating the project says “I wouldn’t look to any one of our events or projects as a distillation of our goals; instead, each functions as a building block to a more environmentally sound future.”

Event: Armour Our Shore

In 2014, across from the visitor center near the “cement” ship, the S.S. Palo Alto Project partnered with Save Our Shores and the Public Art class of Professor Dee Hibbert-Jones to bring art to the shores of the park. Joined by local students of the Mt. Saint Madonna Middle School, teams performed skits to highlight the state of our waters. Alongside the plays were information rich posters covering various issues concerning the oceans as well as activities to further engage with the public. Local television broadcasters were present to cover the event.

Art: Fish Pack Your Trash

Kim Abeles from the S.S. Palo Alto Project has created the “Dolphin Suitcase” made from found trash that had washed up on the beach. The suitcase is a functional “prop” made up of disposable silverware, lighters, straws, and much more. Inside are larger pieces of trash. Abeles, accompanied by her Dolphin Suitcase, visits classrooms and teaches about how trash can become part of the pollutants that get into streams, and then flow into rivers and the ocean.

The exterior detail creates reality. Every kid knows about a drinking straw, and they think of it as one. When they see them all collectively, it begins to have an impact that statistics or facts alone really couldn’t do. Image: Kim Abeles

The interior contains larger objects found in streams and rivers. These are secured with snaps and bindings, then presented home-shopping-network-style during the performance. Image: Kim Abeles

Dynamic Art: Bike Around the S.S. Palo Alto

The Velodrome Powerstation Project by Nathaniel Freeman and Paul Hempstead, aims to have people bike around a the S.S. Palo Alto on a temporary platform. The bikes are set up with batteries charged by the human-mechanized energy of the riders. These batteries are then plugged into a charging station (in visual range of the Moss Landing coastal power station located 20 miles south) that serves as the central power source of the structure itself, as well as being available for visitors to charge personal electronic devices.

The structure is designed to mimic the existing architectural elements of the pier, and will use reclaimed and sustainable materials as much as possible. The walkway is made in part of a transparent material to allow for views of the vessel and the surrounding water; the same material is used to surround the interior of the track, ensuring rider safety and a clear view of the ship. The project aims to produce enough energy to sustain itself, as well as to incite visitor dialogue and create experiential learning opportunities for alternative energy generation.

The Lighthouse at Año Nuevo Island: Shipwrecks and Sea Lions

Ranger Lautamo — Wed, 12 Oct 2016 16:00:20 +0000

It’s usually a fair bet that where there is a lighthouse, there is a history of shipwrecks. The area around Point Año Nuevo along California’s Highway 1 between San Francisco and Santa Cruz is no exception. The wreck of the Coya in 1866 claimed the lives of all but three of the 30-member crew and led to the installation of a steam fog whistle on Año Nuevo Island six years later (it is visible from the beach covered in elephant seals). That same year, the first light went on at the new Pigeon Point Lighthouse.

A High Price for an Ocean View

The first settlers on the island, who were to operate and maintain the whistle, paid a heavy price for their waterfront vista. In 1883, the lighthouse keeper, Henry Colburn, along with his assistant and two neighbor boys, drowned in the large surf while rowing out to the island. Even with keepers like Colburn risking their lives to lead captains and their crews to safe passage, large ships continued to crash between Pigeon Point and Point Año Nuevo. Finally, in 1890, a light was installed on the island.

The keepers had to monitor the new light 24 hours a day and constantly scan the horizon in search of approaching fog. Perhaps the most difficult part of life on the island, though, was dealing with the sea lions that regularly overran the gardens and occasionally even the house.

Make Way for Pinnipeds

In 1948, the last keeper and his family moved off the island and was replaced by a marker buoy with an automatic light, sound, and radar reflector. Ten years later, the California Department of Parks and Recreation acquired the Año Nuevo State Reserve, including the island, which was classified as a scientific preserve. In the early ‘60s, after visitors to the island damaged the existing structures and deterred sea lions and elephant seals from returning to the island, the preserve was closed to the public.

Today, only researchers and designated personnel are allowed on the island, and just the three structures remain: The keeper’s dwelling (built in 1906), the fog signal building (front section built in 1881, back section in 1899), and the fuel storage building (built in 1908). Researchers use the fog signal building to store their equipment and as a respite from the howling winds. Not surprisingly, the dilapidated keeper’s house is still overrun by sea lions, the rightful owners of this rugged island.

When Money Washed up on the Shores of Greyhound Rock

Teeming with more than 300 species of invertebrates, fish, seabirds, and marine mammals, the Greyhound Rock State Marine Conservation Area on California’s central coast is a biodiversity hotspot. Giant kelp forests harbor abalone, juvenile rockfish, and a multitude of other marine invertebrates. Whales and dolphins feed offshore. Brown pelicans and Caspian terns dive for fish. And the bold red beak of the black oystercatcher flashes in the sun as it hunts for mussels and limpets in the rocky shallows.

When Snail Shells Were Currency

Around 300 to 500 years ago, purple olive snail shells (Olivella biplicata) could buy you nutritious seeds or a big hunk of tasty game meat. The shells were recognized by indigenous peoples throughout California as currency. This gave the Cotoni, who lived in the area around Greyhound Rock, a big trading advantage.

If you’re visiting the beach at Greyhound Rock, see if you can spot one of the smooth, oblong purple shells and try trading it with a fellow beachcomber for, say, a watch or smartphone. You probably won’t get more than a concerned look of confusion in return.

That transaction would have failed for the Cotoni, too, because for the snail shells to have any economic value, they had to be made into beads. The Cotoni dried the shells to remove the organic remains (snail guts), ground off the tips so they could be strung onto a cord, smashed the shells into smaller parts, and then reshaped the shell fragments by using a pump drill. They used the beads for trading but also as jewelry and as ornaments on clothing and weapons.

Money may not grow on trees, but for a time, it did wash up on shore for easy collecting at Greyhound Rock.

Elkhorn Slough Sea Otters Offset Agricultural Runoff

Ranger Lautamo — Wed, 28 Sep 2016 20:00:53 +0000

Today, much of the land surrounding Elkhorn Slough near Monterey, California, is managed to reduce nitrogen input. Nevertheless, there is still 150 times more nitrogen in the slough than a century ago. Because of those levels, Elkhorn Slough mudflats are often covered in a thick, green sludge of nitrogen-loving algae. Algae could also be growing on eelgrass, blocking its access to light. Instead, the slough harbors beds of healthy, dark green eelgrass. So what’s the secret? It turns out to be everyone’s favorite keystone predator, the California sea otter.

Otters help keep kelp forests healthy and also contribute to healthy eelgrass habitat. Photo: Bart Selby

Brent Hughes from the University of California, Santa Cruz was first to make the connection between a charismatic carnivore and an unassuming perennial marine plant. He looked at 50 years of historical data that compared areas with and without otters and discovered that areas with larger populations of sea otters had healthier beds of eelgrass (Zostera marina).

Everyone’s favorite keystone predator, the California sea otter. Photo: Bart Selby

The reason: Otters love to eat crabs, which love to eat grazing invertebrates such as sea slugs, which love to eat the algae that grow on eelgrass.

This pup will learn to eat crabs from its mom, indirectly protecting eelgrass habitat. Photo: Bart Selby

This top-down management of species is known as a trophic cascade. A top predator alters the abundance of its prey, which in turn reduces predation on the next trophic level down the food chain.

The trophic cascade at Elkhorn Slough. The top predator is the sea otter (E. lutris), the mesopredators are crabs (Cancer spp. and Pugettia producta), the epiphyte mesograzers are primarily an isopod (I. resecata) and a sea slug (P. taylori), and algal epiphyte competitors of eelgrass primarily consist of chain-forming diatoms, and the red alga Smithora naiadum. Solid arrows indicate direct effects, dashed arrows indicate indirect effects, and the plus and minus symbols indicate positive and/or negative effects on trophic guilds and eelgrass condition. C, competitive interaction; T, trophic interaction. Image: Original artwork by A. C. Hughes and used with permission of the Proceedings of the National Academy of Science 2013 (see full citation below)

You can see the difference between an area with otters and one without when you look at Elkhorn Slough compared to Tomales Bay. Even though Tomales Bay has lower levels of nutrients (such as nitrogen from fertilizer), it has significantly fewer otters. The result is brown eelgrass covered in algae. Without as many otters preying on the crabs, the crustaceans are four times as abundant and 30% bigger than the crabs in Elkhorn Slough. This leaves very few sea slugs to keep the eelgrass grazed clean of algae.

Where to See the Sea Otters

For the best view of sea otters, visit the Moss Landing Wildlife Area (on the east side of Highway 1) or Moss Landing State Beach (on the west side of Highway 1, just off Jetty Road). At the beach on the same side as the harbor, you can often see a raft of male otters floating together out on the open water.

Elkhorn Slough – A Protected Place for Otters and More

Elkhorn Slough is one of the few coastal wetlands remaining in the state, second in size to San Francisco Bay. At nearly 7 miles long, this estuarine waterway shelters an abundance of marine life, providing essential habitat for over 700 species, including aquatic mammals, birds, fish, invertebrates, algae, and plants. It is also part of California’s statewide program to establish Marine Protected Areas (MPAs). MPAs are a lot like our landlocked state parks except that they extend many miles off our coastline. These “underwater parks” are established in areas that are biologically diverse (lots of different marine species), culturally rich (think sunken ships like the S.S. Palo Alto and buried anthropological treasure), and economically important (fishing and tourism are a big deal to these coastal communities).

Elkhorn Slough is home to three marine protected areas—Elkhorn Slough State Marine Conservation Area (SMCA), Elkhorn Slough State Marine Reserve (SMR), and the Moro Cojo Slough SMR. There are several different types of MPAs, and each one has its own set of rules. See the California Department of Fish and Wildlife website for details.

Why There Is No Beachfront Resort at Seacliff State Beach

Ranger Lautamo — Wed, 21 Sep 2016 20:00:45 +0000

Almost a century ago, there were big plans for the northern California coastline along Seacliff State Beach. But sometimes, even the grandest of plans can’t hold up to the power of the ocean.

In the 1920s, a group of ambitious businessmen purchased the land at Seacliff and made plans to build an esplanade, pleasure pier, 2000-foot seawall, bathing pavilion, dining hall and dance pavilion, parking lot, and modern beach bungalettes (a type of small mobile home) right on the wave-washed sand. The only part of their plan that worked out long-term is the parking lot.

Seawall Scores Two, Developers Zero

We now know what a futile plan it is to build right on the beach. This volatile landscape can be a wide open stretch of sand in the morning and be entirely underwater by sunset. Waves from just one storm have the power to crumble cliffs that have stood for millennia. Still, the new owners of Seacliff believed their seawall could withstand the relentless force of the ocean. This was perhaps understandable, because Santa Cruz had only mild winters from 1916 to 1923.

The first seawall was built in 1925. Photo: Courtesy of John Hibble and the Aptos History Museum

Unfortunately, in 1926, almost as soon as construction began on the seawall, a storm caused serious damage. After investing in repairs and reinforcement, another storm the following year wiped out the remainder of the wall.

The seawall was not working, but perhaps there was a different solution?

Sailing to the Rescue (Temporarily)

The developers decided to abandon the seawall idea, because they were quickly running out of funds. Instead, they purchased a surplus concrete oil tanker, the S.S. Palo Alto, to use as an amusement center.

Before the S.S. Palo Alto was anchored at Seacliff, it was part of a fleet of concrete ships built for WWI. Concrete seems an odd choice for a mode of transport that needed to potentially withstand multiple submarine attacks, but steel was scarce and very expensive during the war, so the U.S. decided to experiment with concrete. The U.S. Shipping Board Emergency Fleet Corporation invested in a total of 38 concrete ships. Only eight were ever built, and the S.S. Palo Alto wasn’t completed until after the war ended. She made two independent voyages (no towing required) until she was sold to the Seacliff Amusement Corporation in 1929.

The concrete ship was towed to its place just offshore on January 25, 1930. A 630-foot pier was built out to her massive decks, and she was opened to a waiting crowd of 3,000 people on June 21 of that year. That’s not a bad reception for a WWI ship that didn’t even sail until after the war.

As an amusement center, the S.S. Palo Alto had a dance floor, cafe, a 54-foot heated swimming pool, and a casino. She lasted only two summers against the ocean’s powerful waves. A winter storm cracked the brittle hull in 1932.

The S.S. Palo Alto lasted as an amusement center for just two years. Photo: Courtesy of John Hibble and the Aptos History Museum

That same year, the Seacliff Amusement Corporation went bankrupt. The state bought the ship in 1936 for only a dollar but had to invest in multiple costly repairs as the ship battled the elements for the next 42 years. The ship was finally closed to the public in 1978.

Today, the ship is still battered by the surf. Most recently, a storm in mid-January of 2016 caused a new break in the back half of the ship. That pushed the bow skyward as the stern sunk into the waves.

Envisioning how this sinking artifact could have hosted hundreds of beach-goers for a day or evening of entertainment now requires a large stretch of the imagination.

Protect the Oceans

Sea Cliff State Beach is part of California’s statewide program to establish Marine Protected Areas (MPAs). MPAs are a lot like our landlocked state parks except that they extend many miles off our coastline. These “underwater parks” are established in areas that are biologically diverse (lots of different marine species), culturally rich (think sunken ships like the S.S. Palo Alto and buried anthropological treasure), and economically important (fishing and tourism are a big deal to these coastal communities).

However, these special places are threatened by things such as overexploitation, climate change, pollution, and habitat destruction, so they now require management to recover. Like state parks, MPAs allow the public to enjoy these natural treasures but with a few ground rules about fishing, boating, and other recreational and commercial activities. There are several different types of MPAs, and each one has its own set of rules. See the California Department of Fish and Wildlife website for details.

Soquel Canyon SMCA captures an entire side-branch of the Monterey Submarine Canyon – from relatively shallow waters at the canyon’s head to very deep waters. The rocky canyon walls and mud-and-sand canyon floor offer ideal habitat for rockfishes including depleted species. It contains communities of fragile deepwater corals and sponges. The area is also an important seabird forage grounds and whale feeding area. Portuguese Ledge State Marine Conservation Area protects important refuge habitat for several overfished deepwater rockfish species and is expected to contribute to the recovery of these species.

Where Have All the Bridges Gone at Natural Bridges State Beach?

Ranger Lautamo — Wed, 14 Sep 2016 20:00:26 +0000

The name Natural Bridges may seem deceiving when you first visit the state beach at the end of West Cliff Drive in Santa Cruz, California. Just one picturesque rock arch stands offshore in the crashing waves. You can’t even call it a bridge because it doesn’t connect to anything.

The three natural bridges circa 1900. At this time they were connected to land so technically are considered arches as well as bridges. Photo courtesy of Frank Perry and UCSC Special Collections

So why does the name imply multiple bridges? Perhaps Alexander Weiss, one of the local park rangers back in the ’70s and ’80s, said it best in his poem, “Ode to the Natural Bridges Arch” (see the end of this post for the complete poem):

Once three arches stood in this park
As if windows to the sea,
But wind-blown sand and storms like sharks
Attacked them constantly

The two remaining natural bridges circa 1950. Photo: Courtesy Frank Perry

Time Takes Its Toll

Before 1905, two additional stone arches connected today’s remaining arch to the cliffs where the parking lot sits today, forming three natural bridges. This cliff was once a long, narrow peninsula before the ocean eroded away everything but the middle section, which is now the last arch. Bridges typically form in peninsulas like this one as the waves are bent around the headland, focusing energy on both flanks. The waves sometimes erode caves on either side of the rock that eventually meet, or the bridge can originate from a small hole that grows bigger over many years and eventually erodes through to the other side.

Waves both created and destroyed the three bridges that once stood at Natural Bridges State Beach. Photo: Santa Cruz Museum of Art & History

At Natural Bridges, the rock is Santa Cruz Mudstone, which is fairly resistant to erosion. This means that after a bridge is formed, it will last for decades. Eventually as the base of the rock erodes, the opening enlarges until the entire formation collapses, as did the outermost bridge sometime after autumn of 1905. Some believe that the 1906 earthquake caused the collapse, but there’s no evidence to prove this theory. It was probably just time taking its toll.

The second-to-last arch came close to collapsing in winter 1979. Photo: Courtesy of Frank Perry

In 1974, a couple was married atop one of the two remaining bridges. Their wedding day marked the last time visitors were legally allowed onto the eroding mudstone formation. Six years later, on the dark and stormy night of January 10, 1980, the bridge closest to shore gave way. The park rangers were so saddened when the second bridge fell that they held a wake to commemorate its passing. Alexander Weiss, a park ranger, recited this poem that he wrote for the occasion:

Ode to the Natural Bridges Arch
By Alexander Weiss
January 13, 1980

Once three arches stood in this park
As if windows to the sea,
But wind-blown sand and storms like sharks
Attacked them constantly

This force made one disappear
Sometime ’round 1900;
The other two, like some stone brassiere
Would not be split asunder

But time and storms, they do not care,
And the near arch slowly shed
Bits and pieces here and there
Til it looked quite underfed

In February ’79
That shed quite a chunk,
And again in October, into the brine
Went some more kerplink! Kerplunk!

The arch now was thin and weak,
But gave not up and stayed;
As if it had some goal to seek,
It saw the new decade!

But as the seventies passed on
And the eighties had begun,
It knew it could not last for long
For it was erosion’s son:

For through erosion it was born
And through erosion it would die
And such a death one does not mourn
One merely says goodbye.

The night of January 10th
It gave up the ghost,
And we are here not to lament,
But to offer it a toast:

Here’s to arches that are gone
And to new ones on the way,
For just as sure as there’s a dawn
There’ll be some more some day!

And to our last remaining arch
That now stands like some island fort,
We pledge that we will always march
To give our arch support

Surfing over Kelp Forests at Cove Beach

Marine Protected Areas (MPAs) run along the coastline of California. They were created to maintain the precarious balance between keeping places wild and allowing people to interact with the landscape. In the Año Nuevo MPA, 55 miles south of San Francisco and 20 miles north of Santa Cruz, lies Cove Beach. This is a popular spot for seasoned surfers who fear the loss of this rugged coastline more than the great white sharks cruising the waters in search of fat seals. Gary Strachan, a park ranger and wildlife biologist, is often one of these surfers. He has seen firsthand how the waters have changed over the decades.

The Loss of Kelp Forests and a Killer Surf Break at Cove Beach

In the summer of 1967, large kelp harvesting boats anchored in the bay and started harvesting kelp. By the end of the summer, the surfers noticed that the waves were choppy or “blown out” on windy days and could be hard, even dangerous, to surf. It seemed that the removal of the kelp patches was affecting the surf. Who knew what implications this massive harvesting could have on the marine ecosystem? Anecdotal evidence from fishermen says that the fishing was much better before the harvest, but scientific data on kelp forests goes back only to 1984. Even recent data does little to clear up the mystery.

A 2008 baseline data collection study surveyed the species found in kelp forests at 14 central coast MPAs. Surprisingly, their data showed that the density of a kelp canopy was not related to the number of species found within the canopy. In fact, sometimes more species are found in areas of sparse kelp canopy cover than in areas with dense canopy cover.

Harvesting of kelp at Año Nuevo Bay, by hand, was allowed until early 2016, when it’s status changed from a State Marine Conservation Area to a State Marine Reserve. As a Reserve, it has the highest level of protections and the take of all living, geologic, or cultural marine resources is prohibited. Blown-out waves or not, plenty of surfers still flock to this section of coastline in addition to hundreds of elephant seals.

At Moss Landing, Highway 1 crosses over Elkhorn Slough, one of the largest estuaries in California. Estuaries are places where the sea meets freshwater. They are home to a rich array of plants and animals that can live in this unique habitat. At Elkhorn Slough, the seawater enters the estuary at the harbor mouth directly west of the Highway 1 bridge, and freshwater comes from several sources: the Salinas River; Tembladero Slough, which runs south of Castroville; and upland creeks that feed into both Moro Cojo and Elkhorn sloughs.

People have lived along the shores of Elkhorn Slough for at least 8,000 years. Successive waves of people have used the slough in different ways, including harvesting shellfish, fishing, hunting, agriculture, and even helping to generate electrical power. Conservation work in the last few decades has protected much of the natural habitat at Elkhorn Slough and has restored areas that were impacted by earlier human uses.

Today, it is one of the largest and most ecologically important estuarine systems in California. It provides habitats for native shorebirds, marine mammals such as sea otters and sea lions, and a wide variety of marine invertebrates. The slough also serves as an important nursery for a variety of fish species.

Habitats and Wildlife at Elkhorn Slough

Elkhorn Slough tidal habitats encompass extraordinary biological diversity, providing critical habitat for more than 135 aquatic bird, 550 marine invertebrate, and 102 fish species. The slough is also home to sea lions, harbor seals, and California sea otters. More than 200 different bird species use the slough as a resting spot during their annual migrations.

The upland habitats within the watershed include three of the top 10 most imperiled US habitats: freshwater wetlands, coastal prairie, and maritime chaparral. These systems are amazingly diverse, with coastal prairie being the most species-rich grassland in North America.

Along with providing habitat for a diverse range of life, wetlands provide a critical service to the environment. They provide a buffer between land and sea, which protects the water from soil erosion and protects the land by reducing the impact of flooding. As natural filters, wetlands can remove impurities from the water before they enter our streams and oceans.

Estuaries like Elkhorn Slough are among the most threatened ecosystems in California, facing rates of habitat loss between 75 and 90 percent. As a result, a disproportionate number of rare, threatened, and endangered species reside in these areas. In the Elkhorn Slough watershed, two dozen species are included in these categories. Because experts recognize the value of these resources to the country, the National Oceanic and Atmospheric Administration (NOAA) designated areas of Elkhorn Slough as part of the Monterey Bay National Marine Sanctuary and as a National Estuarine Research Reserve.

There are few native oysters left in Elkhorn Slough due to overfishing in the 1920s and habitat burial by sediments. Restoration work is underway. In this photo the growth rates of native oysters are being surveyed. Photo: Elkhorn Slough Reserve

Moss Landing Harbor

The estuary habitats were profoundly affected by the creation of the present day Moss Landing Harbor. In 1947, just two years after the end of World War II, the Army Corps of Engineers dredged a channel through the barrier dunes for a new harbor entrance.

World War II had greatly restricted commercial fishing, so when the war was over, development of a commercial fishery in the area became a priority. An opportunity to increase access to fertile fishing areas in Monterey Bay was realized by expanding the harbor at Moss Landing. Today, Moss Landing Harbor is a center for commercial and recreational fisheries, public boating tours of the Monterey Bay and the Elkhorn Slough, kayaking, and world-renowned ocean research facilities.

Changes to the mouth have had ripple effects up the slough. The main slough channel has continued to widen and deepen since it was first dredged decades ago. Scientists at the Elkhorn Slough Reserve are currently studying the long-term effects of these changes.

Why Chinese Fishermen Were Chased Away from the Monterey Bay

Ranger Lautamo — Wed, 17 Aug 2016 20:00:06 +0000

Santa Cruz was not always the open-minded, progressive community that it is today. In the mid 1800s, the Northern California beach town was known as the national epicenter of anti-Chinese laws and regulations, even though the Monterey Bay regional economy depended on Chinese as laborers in agriculture and for building railroads.

The Chinese were also very skilled fishermen, and in the 1870s, they caught most of the fish around the Monterey Peninsula. By 1878, they were catching half of all fish caught in Santa Cruz County. Chinese fish peddlers were a common sight walking along the streets of Santa Cruz, Capitola, Soquel, and Watsonville, their shoulders hunched with the weight of bamboo poles hung with fish baskets.

Their success in the fishing industry angered the other local fishermen, who were mostly Italians and Portuguese at the time. They urged political leaders to push the Chinese off the beaches with local ordinances that were rigorously enforced in Santa Cruz County. By the 1880s, Chinese fishermen had been pushed completely out of the Monterey Bay area.

The Chinese Exclusion Law

The Chinese Exclusion Law of 1882 was the first immigration law in the U.S. that restricted a particular race from entering the country. The Geary Act of 1892 extended this law for another 10 years and required Chinese immigrants to carry ID cards at all times. Other laws forbid the use of carrying poles on public streets (the same poles they used to peddle their fish), as well as “Chinese activities” such as flying kites. Those of Chinese descent were also commonly the target of acts of violence.

Before the laws were passed, there were several Chinese fishing villages throughout Monterey Bay. One was located just north of Seacliff at a beach that was then called China Beach. The village consisted of 29 Chinese fishermen (no women or children) living in a ramshackle structure of driftwood and shakes at the base of the high bluffs. Atop those same bluffs now sits one of the most popular campgrounds in California: New Brighton State Beach.

Chinese Fishing Villages Trumped by Tourism

When the railroad finally connected Santa Cruz to the San Francisco Bay Area via Los Gatos in 1875, it opened a gateway to tourism but closed the door of opportunity for the Chinese fishermen in Monterey. Thanks to the railroads, more fishermen and visitors of European descent came to Santa Cruz and the Monterey Bay region, and the Chinese were viewed as unwanted competition. The Chinese peddlers and fishing villages began to disappear just three years later.

In 1878, Camp San Jose opened on the bluffs above what is now New Brighton State Beach to accommodate the many tourists arriving on the new train. Shortly thereafter, the Chinese were forced to move their fishing villages there and told to move farther down the coast.

As the railroad moved south, the Chinese fishermen were continually pushed farther south also. The last fishing camp was set up near the mouth of the Pajaro River at Camp Goodall. By 1888, this camp closed too, and fisherman of Chinese descent had moved away from the Monterey Bay completely.

The site of the fishing village at New Brighton State Beach is now marked only by restrooms built for the many tourists who flock to this sunny stretch of sand. There is only one known photograph of the village that shows the precarious driftwood structure that the fishermen called home.

Multitudes of Monarchs at Natural Bridges State Beach

For decades, tens of thousands of West Coast monarch butterflies (Danus plixippus) have overwintered at Natural Bridges State Beach in Santa Cruz, California. From October through March, in the park’s wind-protected grove of eucalyptus trees, the monarchs rest from their long migration. Thick clusters of monarchs intertwine their legs and hang from the branches like orange leaves, except that these leaves take flight when the temperature rises above 55 degrees Fahrenheit.

Monarchs are the only butterfly species that takes multiple generations to complete one round-trip migration. They travel 50–100 miles a day to escape the cold, and the round trip requires 4–5 generations to complete. A single generation can make the ~3,000 mile trip south, but the journey back north takes 3–4 generations to complete.

Monarchs that live east of the Northern Rockies overwinter in the Sierra Madre mountain range of Mexico, and those west of the Northern Rockies overwinter along the California coast. The butterflies return to the same groves each year for much-needed rest and to lay their eggs on nearby milkweed, which is the only plant that their larvae can eat.

Monarch populations everywhere have significantly decreased. In Santa Cruz, the population has dropped from a high of 150,000 to just a few thousand butterflies. Both Roundup and deforestation are to blame. Illegal logging has shrunk the eastern butterflies’ winter habitat in Mexico, and the introduction of Roundup-ready corn and soybeans in the US has almost eliminated milkweed from much of their habitat. Fortunately, parks such as Natural Bridges are being actively managed to keep some monarch habitat intact.

A Monarch Refuge

Natural Bridges State Beach park rangers tend a milkweed garden for their winged visitors so the butterflies have a place to lay their eggs. They also maintain adequate shelter for the adult monarchs. Since a fungal disease called pitch canker killed some of the Monterey pines that protected the monarch’s eucalyptus grove from the wind, they have been planting cypress trees in the park as a replacement wind break.

Docents lead tours of the Monarch Grove at Natural Bridges from mid-October through January at 11 AM and 2 PM on weekends. Tours start at the Visitor Center. The park also holds a Welcome Back Monarchs Day on the second Sunday in October and a Migration Festival on the second Saturday in February for the beloved butterflies.

Even with lower numbers than in the past, it is still spellbinding to stand in the quiet eucalyptus grove at Natural Bridges and see the orange clusters of monarchs weighing down the branches. As the temperature warms and the butterflies begin to gently flit around the grove in search of food, their delicate wings glow in the sun like stained glass. The only sound is the creaking of eucalyptus branches, the click of cameras, and hushed murmurs of awe as visitors witness one of nature’s most beautiful phenomena.

Waddell’s Wharf: Ordeals of Shipping Lumber from Año Nuevo Bay

Ranger Lautamo — Wed, 03 Aug 2016 20:00:26 +0000

Over 150 years ago, the coastline at Año Nuevo State Park, between San Francisco and Santa Cruz, California, was home to a bustling lumber industry. Even though the wharf at Cove Beach in Año Nuevo Bay once shipped over two million feet of lumber in just one year, it’s hard to find signs of its existence today. The story of this wharf begins about two miles south of Cove Beach at Waddell Beach, now a popular spot for kite surfers and the coastal entrance to Big Basin State Park. In the 1860s, William Waddell, a failed businessman from Kentucky, built his home, a steam-powered lumber mill, the first of two shipping wharves, and a five-mile tramway here in the canyon that now bears his name.

The millworkers cut an impressive 20,000 feet of lumber a day at the mill’s peak operation. Waddell had one major problem, though: He didn’t have a way to ship his lumber to the market.

A Tale of Two Wharves

To solve this problem, he began construction of a 1000-foot wharf in 1864. He built it at the mouth of what is now called Waddell Creek. Unfortunately, he hit a layer of bedrock after spending $30,000 ($686,000 in today’s money) and had to abandon construction.

Not to be deterred, Waddell built a second, 700-foot wharf at Cove Beach. Less than a year later, the wharf was washed away in a storm. Waddell replaced it, only to have a large portion washed away again in 1870. It took four men and a horse to retrieve that section.

It Ends with a Bear

On an autumn day in 1875, Waddell went hunting with his dog and the local blacksmith. Near the entrance to a ravine, a grizzly bear attacked him, but his faithful dog jumped into the fray and lured the bear back into the woods.

He made it home, but he died five days later from blood poisoning and was buried in the Odd Fellows Cemetery in Santa Cruz. Waddell was one of the last grizzly bear victim fatalities recorded in California before the species went extinct statewide, from hunting, in 1922.

Where to Look for Remnants of the Wharf

A few remnants of the mill and Waddell’s Wharf remain, but you have to know where to look and the last pier has been eroded away from the beach for decades.

Many of the wharf timbers were reused to build the dairy and horse barn at Año Nuevo State Preserve, which are now the visitor center. Boilers from the mill now function as culverts at May Creek and an unnamed stream. And about two-thirds of the way up Waddell Canyon, you can still find four posts from the five-mile tramway.

Timbers from Waddell’s Wharf were salvaged and reused by Edwin Dickerman to build a dairy and horse barn in 1881. These buildings and their supporting wharf-derived beams are now part of the visitor center at Año Nuevo State Preserve. Photo: Mike Merritt

These leftover pieces are reminders that Highway 1 was once a wild place where pioneers tried to stake their claims on the land, only to be knocked back again and again by the forces of nature. Today, we try harder to coexist with these wild places, study them, explore them, and protect them for many generations to come.

Santa Cruz’s Nuclear Power Plant That Almost Was

Ranger Gaudinski — Wed, 27 Jul 2016 20:00:53 +0000

Greyhound Rock lies right next to one of the major faults within the San Gregorio Fault Zone. This fact might be no big surprise in earthquake-prone California, but what is startling is how ridiculously close we came to building a huge nuclear power plant right on top of this active fault zone.

In 1969, Pacific Gas and Electric (PG&E) announced it had leased 6,800 acres of Coast Dairies and Land property and intended to build a 6,000-megawatt-generating nuclear power plant at El Jarro Point, a wide marine terrace between Scott Creek Beach and Davenport Landing. The plant would have stood approximately where Swanton Berry Farm is now and required a major rerouting of Highway 1.

Creation of the plant was inadvertently derailed when a University of California, Santa Cruz (UCSC) geology graduate student named Jerry Weber took a walk on nearby Cove Beach in 1973. Weber noticed that a recent storm had eroded the sea cliff and revealed a large active fault in the cliff face. According to Weber:

“It is a classic exposure of fault movement. The fault had been completely covered by vegetation for probably hundreds of years. If not for the El Niño storms of 1972 and 1973, no one would have ever noticed it.”

The entire zone between the two black arrows is the Frijoles Fault at Año Nuevo/Cove Beach. Notice that it is a “zone” about 70 feet wide. To find it when you go to our Año Nuevo/Cove Beach stop, look for the trees and the slumped area. If you see the dark tilted layer in the cliffs, above the right-most arrow, you know you have found the fault. Image: Julia Gaudinski/Mobile Ranger

In the 1970s, the San Francisco Bay Area was well-known for earthquakes along the San Andreas Fault, of course. But the San Gregorio Fault, which extends from San Francisco to south of Santa Cruz all along the coast, was just being discovered and mapped. Weber’s work was crucial in detailing the faulting around Año Nuevo State Park and Greyhound Rock.

By 1971, a passionate group of people was already on the move to stop the nuclear power plant at El Jarro Point. In September 1971, the Santa Cruz County Board of Supervisors voted 3 to 2 for a moratorium “in principle” on a permit for the plant. But it was really Weber’s discovery of the Frijoles Fault and other faults in the San Gregorio Fault Zone at Cove Beach that stopped the El Jarro Nuclear Power Plant dead in its tracks.

For a nuclear power plant to be approved, there can be no nearby active faults and, in geologic terms, “active” means a surface rupture within the last 10,000 years. By using radiocarbon dating of plant remains at the base of the cliffs at Cove Beach, Weber was able to prove clear movement within the San Gregorio Fault Zone at Año Nuevo/Cove Beach in the last 10,000 years.

A map of the many faults in this area. The fault exposed at Greyhound Rock is still not well mapped. Image: Created by and courtesy of Gerald Weber

Faults from the San Gregorio Fault Zone continue north and south and can be seen in the beach cliffs at Greyhound Rock. Greyhound Rock itself is not faulted.

These cliffs at Greyhound beach clearly show fault movement. The two black arrows point to the most obvious places where rocks have slid past each other. There are likely two other faults in this area two but they are a bit harder to see. Image: Julia Gaudinski/Mobile Ranger

The San Gregorio Fault is long and composed of many parallel faults. At Año Nuevo/Cove Beach, Weber has mapped at least six faults in a zone that is a mile wide. In fact, when you think of faults and earthquakes in general it’s best to think of fault zones or even a system of faults.
Indeed, the San Gregorio Fault Zone is one part of what is now referred to as the San Andreas Fault System because there are several faults involved, including the Hayward and Calaveras Fault Zones and the San Gregorio Fault Zone.

One way to cope with the threat of earthquakes: poke fun at the threat with a t-shirt!

As you enjoy the California coast, keep in mind that it could start moving and shaking at any time. The San Gregorio Fault Zone has moved in the last 10,000 years and it will move again. We just don’t know when. Geologist Gerald Weber admits that he hopes the San Gregorio Fault Zone, which he spent much of his life laboriously mapping, might show some modest sign of movement while he is still alive.

Managing a Strawberry Farm and Protecting the Elkhorn Slough

Ranger Lautamo — Wed, 20 Jul 2016 20:00:13 +0000

Row crops were introduced to the areas around Elkhorn Slough in the late 1800s. The majority of these crops were strawberries because the slough’s perimeter has ideal growing conditions with a moderate climate and well-drained soils.

Strawberries are farmed in abundance around Elkhorn Slough due to the ideal growing conditions. Photo: Sharon Mollerus

The Azevedo Ranch, just about one mile up the slough from the Wildlife Viewing Area, was one such strawberry farm. They grew their berries next to the Azevedo Marshes, a series of pocket wetlands that were cut off from the slough in the 1870s with the construction of a railroad embankment. The strawberries were grown right to the edge of the slough, and like all berry farmers of the day, they applied chemical fertilizers containing high levels of nitrogen to the crops.

Sediments and chemicals from strawberry fields used to run off directly into the marshes. Photo: Elkhorn Slough Foundation

If runoff goes unchecked, the addition of nitrogen can lead to massive algal blooms that deplete the oxygen in the water, making it impossible for almost any other species to survive.

Today, there is a buffer zone of native vegetation that traps agricultural runoff before it reaches the Azevedo Marshes. Photo: Elkhorn Slough Foundation

In 1991, the Nature Conservancy acquired the ranch with funding from the Coastal Conservancy. Soon after, they took the strawberry fields adjacent to the slough out of strawberry production. Instead, they planted a native vegetation buffer. Today, the ranch has 24 acres of native plants between its strawberry producing crops and the marshes. This creates a natural buffer zone that traps nutrients and sediments and decreases nitrogen input into the slough. Azevedo Ranch is still owned by the Nature Conservancy, but it is managed by the Elkhorn Slough Foundation. This is a working example of how agriculture can co-exist next to a natural ecosystem without too much negative impact.

A Great Side Trip

We recommend a visit to the Elkhorn Slough National Estuarine Research Reserve at 1700 Elkhorn Road. They have a visitor center and a wonderful overlook where you can view much of the Elkhorn Slough. There are also five miles of trails to enjoy the grasslands, oak woodland, and wetlands of the Elkhorn Slough. There is a small admission fee for people over the age of 16. If you have a hunting or fishing license, you’ve already paid.

The Evolution of a Monterey Bay Fisherman

Ranger Lautamo — Wed, 13 Jul 2016 20:00:29 +0000

What habitat is deeper than the Grand Canyon, requires a submarine to properly explore, and is home to bioluminescent invertebrates? None other than the Monterey Submarine Canyon, an incredibly diverse habitat that extends 50 miles offshore. It provides unique opportunities for deep sea research, as well as recreational and commercial activities, such as diving and fishing.

This massive canyon is an underwater state park that protects marine life and habitat, known as a marine protected area, or MPAs. Within it, there are two areas that you’ve probably never heard of: Soquel Canyon and Portuguese Ledge. Both are valuable habitats for fish species that used to provide the livelihoods of Tim Maricich and other commercial fishermen.

From Fisherman to Captain for Hire

Maricich represents many fishermen in the Monterey Bay to whom fishing is more than a job. For them, it’s a way of life. He’s been fishing in the Monterey Bay for more than 47 years, and his roots reach back generations to a long line of fishermen in Croatia.

The MPAs in Santa Cruz County. Image: California Marine Sanctuary Foundation

In 2007 when 29 offshore areas in California were designated as MPAs, Maricich’s way of life changed. Even though recreational and commercial fishing for some species are allowed in the Soquel Canyon and Portuguese Ledge (including salmon, mackerel, and sardines), rockfish, the mainstay of many fishermen, are off limits. Rockfish-free fishing zones have helped to rebuild the dwindling populations of a valuable commercial species, but that restriction also cut into the income of fishermen like Maricich.

Fishing regulations along the California coast began several years before the designation of MPAs and have caused a huge shift in the fishing industry. Between 1981 and 2011, the number of registered fishing vessels decreased by nearly 70%. Fishermen were being pushed out of waters that they’d been fishing for decades. The good long-term intention of rebuilding fish populations resulted in the short-term consequence of putting men and women out of work.

Today, Maricich still works on his boat in the Monterey Bay, but he’s letting cowcods and yelloweye rockfish (aka red snappers) swim by unscathed. He now captains a boat full of conservation biologists from the Nature Conservancy, and he’s helping them count fish.

This photo of cowcod (Sebastes levis) was taken in 2007 in the Cordell Bank National Marine Sanctuary. Photo: Dave Murfin/ NOAA

The unlikely partnership between a fisherman and marine scientists helps other fishermen trust data from studies within the MPAs. It also provides an economic opportunity for those like Maricich who have an intimate knowledge of navigating the Monterey Bay in search of fish.

There’s another, less obvious reason for this partnership, though. As journalist Paul Greenberg puts it in an article titled “The Fisherman’s Dilemma,” it also stems from one truth that unites fishermen and conservationists: “After all the closures and commissions, all the surveys and reappraisals, the ocean is still deeply mysterious.”

The Rockfish Return

The ocean is indeed a mysterious place, so scientists and fishermen are continually discovering new species and gaining a better understanding of familiar ones. A 2008 baseline study of the Soquel Canyon and the Portuguese Ledge revealed that the Portuguese Ledge has a high diversity of fish species, and Soquel Canyon is home to high numbers of commercial species threatened by overfishing, including the yelloweye rockfish, bocaccio, and cowcod.

Studies that scientists are conducting with Maricich and other fishermen will continue to shed light on the effectiveness of MPAs. For now, It looks like there’s hope that these fisheries can recover, and fishermen like Maricich can look forward to a stronger industry in years to come, thanks to MPAs.

Natural Bridges State Beach and Fred Swanton’s Development Dreams

In the early 1900s, Natural Bridges was briefly at risk of becoming the site of a grand hotel in line with the vision of Fred W. Swanton. He was fortunate enough to acquire the land that now makes up the state beach through his wife, Emma Stanley Pope Hall.

“Fabulous Fred” Invests in the Wrong Neighborhood

Because he was instrumental in the development of the Casa Del Rey Hotel, the Santa Cruz Beach Boardwalk, two competing electric railroads, and a telephone company, Fred Swanton was a well-known Santa Cruz entrepreneur. He had big ideas and the ability to bring them to fruition. He was also the main person responsible for making tourism the foundation of the city’s economy. “Fabulous Fred” actively promoted Santa Cruz to neighboring areas, even traveling throughout California and Nevada with a marching band to spread the word. However, his plan for a development at Natural Bridges never came to be.

Swanton renamed Hall’s Beach (today’s Natural Bridges State Beach) as Swanton Beach Park and developed streets with the names of bigger cities, including Sacramento, Auburn, and Merced, hoping to attract buyers from the hot Central Valley. He also had plans for a large hotel with modern conveniences to cater to wealthy guests. But the cold winds and damp fog that linger in these neighborhoods, so the story goes, deterred Swanton’s prospective buyers and led him to financial ruin and bankruptcy in 1912.

Perhaps he was just a bit ahead of his time and there were simply not enough people interested in living year-round in Santa Cruz yet. Swanton Beach Park was, in fact, one of many unsuccessful developments in the early 1900s along the Santa Cruz coast.

Swanton recovered financially and went on to do many other projects, including establishing a landing field at Swanton Beach Park in 1924. Known as Swanton Airport, it was used periodically until about 1931 when the Santa Cruz Airport opened in Capitola.

Unfortunately for Swanton, his financial recovery was only temporary. He filed for bankruptcy again in 1930 and deeded the 27-acre Swanton Beach Park to the state in 1933. He died almost penniless 10 years later. It seems Swanton’s entrepreneurial instincts and management skills waxed and waned over the years, and perhaps this is the real reason that the Swanton Beach Park development failed.

Construction of beach facilities did not begin until 1954, and the area around the park was not developed for housing until the 1970s. Swanton might roll in his grave if he could see the multimillion-dollar homes that now line Swanton Avenue and his city-named streets.

If you’re looking for a resort today, head to the Santa Cruz Beach Boardwalk. But thousands of visitors prefer the tide pools, dune habitat, cool geology, and monarch butterfly refuge that are protected by what is now Natural Bridges State Beach.

Hummingbirds: Anna’s and Allen’s

Anna’s hummingbirds (Calypte anna) are year-round residents of northern California, but they weren’t always. Prior to the mid-20th century, northern Baja California and Southern California were the only places that Anna’s would breed. Hummingbirds have long thin bills and even longer tongues that enable them to reach nectar that most other birds can’t get in narrow tubular flowers, such as monkey flower and manzanita. So their breeding habitat expanded when Californians planted exotic nectar-rich flowering plants in their gardens and hung hummingbird feeders outside.

Allen’s Coming to Town

Anna’s hummingbirds are among the most common hummingbirds along the Pacific Coast, but they are certainly not the only ones. Allen’s hummingbirds (Selasphorus sasin) visit coastal California for their yearly migration from central Mexico. They breed along a strip of coastal California and southern Oregon that includes Santa Cruz.

When they arrive, they make their presence known fairly aggressively. These three-inch birds are extremely feisty for their size, sometimes taking their rivals to the ground. Allen’s hummingbirds are even bold enough to chase off red-tailed hawks and American kestrels from their territories.

At the University of California, Santa Cruz (UCSC) annual Hummingbird Days, Scott Adam described the arrival of the aggressive Allen’s this way:

“When they first arrive, there is a big territory war. They forcibly displace the Anna’s hummingbirds into the surrounding neighborhoods, take possession of the nectar-rich grevilleas in the Australian garden, and then wait for the females.”

The arboretum at UCSC is a hot spot for both the Anna’s and Allen’s hummingbirds because it contains several non-native Australian flowering plants that provide a good source of nectar.

Restoring Native Plants Helps Ocean Birds

Brandt’s cormorants (Phalacrocorax penicillatus) are back on the sea cliff just west of Natural Bridges State Beach in Santa Cruz. They started using this ledge in large numbers in 2011 after the breeding habitat was improved by removing the non-native and invasive ice plant. The Brandt’s cormorants do not nest on top of ice plant and are sensitive to human disturbance. To breed, they need open ledges free of predators and safe from people walking, talking, or sitting to drink coffee.

In the photo above, you can see one Brandt’s cormorant on a nest (the greenish mound) and one empty nest. In April 2011, as part of the West Cliff Restoration Project, local ecologists Bill Henry, Josh Adams, Ryan Carle, and Jessie Beck cleared encroaching ice plant from this ledge. By the next day, a large group of Brandt’s cormorants started building their nests.

The cormorants incubate their eggs for ~30 days, and the chicks leave the nest when they 40–50 days old. When the birds fly from the ledge for the first time, usually in late August, they are not yet strong enough to fly back, so they hang out on the beach below for up to several weeks while the parents still feed them.

In 2011, after the ice plant was cleared, 21 nests were counted and 44–45 chicks were documented as hatching (Alayne Meeks, Oikonos). In 2012, the numbers of nests and chicks hatched were practically the same. The ledge was not used again for breeding from 2013 through 2015, but it was used again in spring 2016, with 35 birds and 14 nest sites as of May 17.

The reasons for the three-year hiatus are unclear. Fluctuations in the numbers of mating birds might be related to changes in ocean conditions, disturbances, presence of predators, or simply better habitat conditions elsewhere. In many years, the Brandt’s cormorants nest on the remaining Natural Bridges arch, less than 100 yards away. The same population might even alternate between the two sites.

Native Plant Restoration Is for the Birds

Although Brandt’s cormorants are not a threatened or endangered species, they are vulnerable to the loss of breeding habitats, including the erosion of offshore rocks, such as the remaining arch at Natural Bridges State Beach. Potential mainland breeding sites are heavily impacted by coastal development, coastal armoring such as sea walls, rip-rap (1– to 2–ton boulders placed in a group), invasive vegetation, and predators. Clearing of ice plant on West Cliff Drive provides more places for the birds to breed along the shore.

Bill Henry, a local scientist, has spearheaded removal of ice plant and restoration of native plants along West Cliff Drive since 2012. Henry’s goal is to restore plant biodiversity, increase habitat, and engage the public in stewardship of the coast. An example of this restoration work can be seen just a few hundred feet to the east of the Brandt’s ledge pictured above (just past Chico Avenue).

The plot was cleared of ice plant and replanted in spring of 2012. The native species planted include California sagebrush, coast buckwheat, dudleya, lizard tail, seaside daisy, sticky monkey flower, prunella, and yarrow, all grown from locally collected seed. These plants are typical of the northern coastal sage scrub habitat that was here before it was displaced by ice plant. The restoration sites are already supporting increased faunal diversity, including native bees and birds.

Restored coastal sage scrub vegetation also surrounds the Seymour Center at the Long Marine Lab.

The work was initially the West Cliff Restoration Project of the nonprofit Oikonos. Since 2012, partners and volunteers worked along West Cliff Drive (at Lighthouse Field, for example) and at the entrance to Seabright Beach. The project has since become a separate organization, Groundswell Coastal Ecology. Groundswell enhances coastal resources in Santa Cruz by pairing education, community activities, and science with ecological restoration. Sites include Seabright Beach, Lighthouse Field (across from the surfer statue), and Natural Bridges. Their 2016–17 plans include planting of more than 10,000 native plants along the Natural Bridges headland.

Volunteer for Restoration

If you are interested in participating in the coastal restoration process or want to receive Groundswell updates, please send email to info@groundswellecology.org. Groundswell ecologists are seeking volunteers to assist with seed collection and plant propagation, which will support the 2016–17 restoration season.
