Helping the Natives Return
"We do what is necessary and no more
than is necessary."



The native Pink Flowering Currant bushes on the Reserve attract native insects like this Bombyliid, or "bee fly." (Click here for more info on the insect, and here to see this photo full size in a new window.)

It took 15 people two weeks to clear 500 acacia trees from Long Valley. It cost $20,000 to remove half the pampas grass from El Chamisal Ranch. Every spring, our land staff’s number one job is controlling weeds like poison hemlock. Why do we spend all this time and money getting rid of these plants? The answer is so that other plants – native plants – can return to the ecology of Elkhorn Slough.

The return of native plant life often begins with removing the invasive non-natives that have displaced the natives. Left unchecked, the acacia trees would have choked out the native oak trees and filled the pocket meadows in Long Valley. Without removal, the pampas grass that blanketed hillsides on El Chamisal would have continued to spread up the hills to push aside the rare maritime chaparral on ridge tops on all our lands. If we left hemlock alone, it would spread even further across our lands, crowding out native bunch grasses and wildflowers that have managed to survive their near total elimination.

The preference for native plants – and the hostility towards invasive non-natives – is sometimes misunderstood as a kind of environmental purism. The central biological reason for the preference for natives is implied by their definition. They are the plants that have evolved in a given area for thousands of years and are part of an ecological web of animals, fungi, and microbes that thrive together. They are a well-fitted part of an elaborate web of life, and their disappearance threatens the entire web.

The hostility toward “invasive non-natives” is implied in the term itself. Non-natives are plants that were introduced into this complex local web, primarily through human activity. The vast majority of non-native plants now in California arrived with European settlers, some accidentally (as contaminants in grain, for example) and some intentionally, for food or fiber.

The first comprehensive report on the state’s plants was in 1925, and it listed 292 established non-natives. Eighty years later the number of non-natives has grown to 1045. There are 6300 native plant species in our biologically rich state.

Most of these non-natives are ecologically benign because they are not invasive – that is, they do not invade and displace natives. We see no hillsides taken over by European petunias. Fewer than 10 percent of the 1045 non-native plant species in California are recognized as serious threats. But the hundred or so that are serious threats do vast ecological damage by outcompeting native plants, displacing them, and tearing the web of life of which the natives are a part. Perhaps the most dramatic example in California is the invasion of annual grasses and plants from the Mediterranean region which have replaced most of California’s native grasslands – an invasion so complete that we do not know what the native species were on vast areas of grassland throughout the state.

The preference for natives, then, is a preference for biological diversity and health. It is also, at base, built on the notion that “mother nature” really does know best, that these plants evolved over thousands of years in this spot and, for that reason, we should do our best to leave them be. As stewards of the land, our motto should be something like the physician’s command when caring for the human body: first, do no harm.

Invasive non-natives
Some of the 3400 acres of land under ESF’s care are remarkably free of invasive non-natives. When Kim Hayes began her job as our Land Manager, she was surprised at how often she found these pockets of plant communities that are virtually untouched. Large sections of Long Valley remain as they have been for hundreds of years. The grasslands at Porter Ranch have some of the healthiest bunch grasses in the watershed. The ridge tops that crisscross our lands are covered with a quarter of the watershed’s rare maritime chaparral – with very little weed invasion.

In other areas, invasive non-natives have established themselves and pose significant challenges for our land management staff. The Hambey Ranch has major invasions of virtually every non-native in the watershed: cape and English ivy choke oak groves, pampas grass pushes out maritime chaparral, eucalyptus fills coastal grasslands. We also have problems with veldt grass at Brothers, which is a major threat to grasslands and other plant communities throughout Monterey County.

Five of the 20 most invasive non-natives on the “A list” of the California Exotic Pest Plant Council are well established on ESF lands, including ice plant, pampas grass, French broom, veldt grass, and cape ivy. None of our properties is free of problems, but some have more problems than others, and they are always the ranches which have experienced the most recent and damaging human disturbance. The steep hills of El Chamisal were abandoned farm fields, and pampas grass has thrived in the disturbed soil.

Controlling non-natives and helping natives
We are used to thinking about restoration as planting natives. The phrase brings to mind dozens of volunteers patiently planting thousands of delicate native plants one by one. This winter, volunteers for the Elkhorn Slough Reserve and ESF did just that, emptying a greenhouse of 6000 native plants and planting them on Reserve and Foundation lands. ESF has planted tens of thousands of native bunch grasses and scores of oaks on Blohm Ranch. Last winter we planted native chaparral plants and seeds that were gathered at Blohm on old farm roads at Elzas. In recent years, our big erosion control projects at Blohm and Hambey have included planting perennial natives in grassed waterways and on the berms that form sediment basins.

This stage of restoration – the actual planting of natives – is just one part of the job of returning natives to the land. Land Manager Kim Hayes lists the stages that precede the planting stage. You have to remove the conditions that help non-natives spread. Non-natives thrive in severely disturbed soil, which is why pampas grass is worse at El Chamisal, and why poison hemlock is thickest at the Reserve, which was heavily disturbed by decades of intensive grazing.

Before you plant, you sometimes have to clear out or reduce the invasive non-natives. At the end of Long Valley there is a pond which has both poison hemlock and a still healthy base of native wetland grasses. Kim’s approach is to take out the hemlock and thus help the perennial wetland grasses come back. “We’re trying,” she says, “to outcompete the hemlock.” This may be possible at this pond in Long Valley, and the use of this approach there is an example of the hundreds of on-the-ground judgments Kim makes as part of her work restoring the health of ESF lands. “We start by controlling the weeds,” she says, “then evaluate the health of the native system. Sometimes the natives are strong enough and just need a little help. We try to do what is necessary and no more than is necessary.”

There is perhaps no better example of the “what is necessary and no more” approach than the way ESF cares for the Porter Ranch grasslands. The 200+ acres of grasslands rise up from the east end of Porter Marsh and crown the hills on the south side of the Pajaro Valley. You drive by these hills where Hall Road becomes Elkhorn Road. These hills were in the Porter family since the 1870s and were bequeathed to the Elkhorn Slough Foundation in 2001. They have been well cared for lands, with minimal damaging disturbance.

The Foundation, like the Porters before them, grazes cattle there, leasing the land to Joe Morris. Joe practices “holistic planned grazing,” an approach which mimics the grazing practices of the wild herds that were here before Europeans. The land is not overgrazed (too many animals per acre for too long), which leads to the highly disturbed conditions that are breeding grounds for non-natives. It is grazed for shorter periods, allowing the cattle to eat the non-natives and allowing the natives time between grazing to flourish. The result of this legacy of minimal disturbance and the current practice of holistic grazing is a healthy grassland with the watershed’s greatest concentration of native bunch grasses and wildflowers.

Another sign of a healthy native plant community is a healthy native animal community, which makes sightings – like a recent one of a burrowing owl at Porter – not just exciting, but hopeful. The natives are returning – and we are helping them.

"It's an honor doing this work."
An interview with Ken Collins
(a.k.a. Land Dude)


Ken Collins became our Assistant Land Manager in January 2000. We sat down with him in April to talk about his job.

You’ve been with ESF for four years now. How has the work changed?


It’s become more defined. There are three definite phases each year. In the fall and winter it’s all about erosion control, getting ready for the rainy season, then responding to it. As soon as that’s over we move into weed control and abatement, exotic plant removal. Then in summer I shift to property maintenance, fixing fences, gates, roads. We have been acquiring land at a really rapid rate, so there’s a lot of work on new properties.

Is there any big project in the past four years that stands out for you as something you’re really proud of?

The one that comes to mind and I feel really passionate about is removing the acacia grove in Long Valley. It was at the heart of Long Valley. Aerial photos made it look like a cancer spreading through the oaks. We’re talking about 500 trees, all coming from a couple of trees apparently planted there in the 1950s.


It took two 15-person crews of CCCs [California Conservation Corp workers] two weeks to clear them [photo, opposite page]. And we still weren’t done, and some of them volunteered to help us finish. I’ll always be able to say that I spearheaded removal of this grove and changed the future of Long Valley. The acacia would have just kept spreading. They grow fast, they’re prolific, they grow taller than the oaks. They would have covered the valley floor. We stopped that. We’re not done because there’s still a huge seed bank there. Every year I go back and spread mulch over the seed bank and remove new sprouts.

You’re out on our land pretty much all the time, so you’re the ESF person who has the most contact with our neighbors. What’s that like?

It’s great! I get to know them, get to talk about what we’re doing on the land. They’re usually pleased to know they’re living next to protected areas. Many of them have a long history in the area and I get to hear their stories and learn more about past land uses. Increasingly, our neighbors are helping us by reporting off-road vehicles or other damaging activities. They’re really helpful in monitoring the properties. We have 3400 acres now, and I can’t be everywhere, so they’re invaluable. Just recently neighbors reported off-road vehicles on our land that led to successful interceptions.

You obviously love what you’re doing, being out on the land. That’s why we call you Land Dude. Where did this begin, this love of the land?

I always loved being outdoors in the elements. I grew up in upstate New York, but it wasn’t until I visited Australia that I realized how special nature is. I was marveling at their animals – kangaroos and Koala bears – and they were amazed to hear about skunks! It’s all special. And then I come to Elkhorn Slough, and we’ve got egrets and herons and all sorts of wildlife in this little area. I’ve seen six bobcats on our lands in the last year! They’re elusive animals, and seeing even one is exciting.
Another thing about this has to do with my father dying. That’s when working to protect the land became a career for me. I asked myself what I wanted to leave as a legacy, and I couldn’t think of anything as valuable as what I’m doing. It’s an honor doing this work.

In Memoriam: Jeff Schrock

Jeff Schrock believed that success comes from doing good work and doing what you love. In 1985 he pioneered eco-tourism on the Monterey Peninsula when he and his wife Cass started Monterey Bay Kayaks in Monterey and Moss Landing.

The business combined his love of the ocean and his ingenuity with boats, while enabling him to reach out to people of all ages and abilities. Since then, MBK has been recognized by numerous agencies for its work promoting marine education, environmental awareness, and ecological stewardship.

A natural outdoorsman, Jeff was equally at home exploring in the ocean, desert, mountains, or canyons. He spent his early years hiking, climbing, and mountaineering, often designing and manufacturing his own equipment. He was also a gifted inventor, creating many of the unique racks and labor-saving devices that make operating a large kayaking outfitter possible.

While growing a business and raising a family, he never let his 15-year battle with a brain tumor slow him down. Jeff will be missed by those who love the slough.

Slough Speak
Terms frequently used in the stewardship work
of the ESF staff

Degraded or disturbed soils: Soils that have been altered by human activity, which makes them less capable of supporting native plant communities and sometimes more susceptible to non-native invasion. In the Elkhorn Slough watershed, the dominant forms of disturbance are the cultivation of steep slopes, erosion, and overgrazing.


Used in a planned disturbance regime, cattle, like these
on Porter Ranch, can help native plants thrive and reduce
invasive non-natives.

Disturbance regime: The disturbance of the soil and plant communities in ways that are natural or mimic natural disturbance and thus foster healthy ecological conditions. The grazing of cattle at the Porter Ranch is an example of a disturbance regime designed to mimic the grazing patterns of wild herds and thus benefit native bunch grasses and grassland-dependant species such as badgers, gopher snakes, white-tailed kites, western bluebirds, bobcats, and burrowing owls.

Native plants: Plants which evolved in and grow naturally in a specific region.

Invasive non-native:
A plant that did not evolve in a particular region but aggressively grows there, altering natural processes and crowding out native plants.

ESF Seeks Funds for Reserve
“These are not Reserve problems, they are
Elkhorn Slough problems.”

The state budget crisis is something “out there” for many of us. But for Reserve Manager Becky Christensen it is on her desk everyday. It comes in the form of requests for things like light bulbs for the Visitors Center, straw for erosion control, and disinfectant to help stop the spread of Sudden Oak Death. Normally Becky would make the decision about whether she could afford these items. But these are not normal times because Becky doesn’t have a basic operating budget.

The Reserve has always operated on a modest budget – and with great volunteer support. Due to state budget problems this year, the Reserve has no operating budget. Now every expenditure must be approved at the state level – and only “emergency” requests are approved.


Some of the 10,000 school children who visit the Reserve
each year line up to use the scopes at the overlook.

To help fund at least some of the basic operating expenses of the Reserve, the Elkhorn Slough Foundation has launched a campaign to raise $20,000. “We’re talking about basic needs,” says ESF Executive Director Mark Silberstein. “These problems are not just Reserve problems, they are Elkhorn Slough problems.”

Silberstein has written a letter to ESF’s 600 members asking them to contribute to a fund to match donations from visitors to the Reserve. “We’re hoping to get $10,000 from ESF members and $10,000 from Reserve visitors,” says Development Director Stephen Slade. “It’s the neighborly thing to do.”

You can track the success of the campaign on our website – and you can contribute there too!

Partner Profile: The Reserve

The Elkhorn Slough Foundation works with many partners, but the Elkhorn Slough National Estuarine Research Reserve has a special status. Our offices are located on the Reserve. The Foundation was created by the Reserve Advisory Committee. Close to half our budget is made up of grants that fund Reserve positions. We are, in some ways, like close siblings who never left the farm, one taking over one aspect of the operation, one another. We have our independence, but we’re working for the same concern.

The closeness, and separation, of this relationship confuses most newcomers, including new staff. “Am I Reserve or Foundation staff?” they ask, and for a third of the 30-some people who work here the answer is a confusing, “Both.” Their jobs are funded by grants from the National Oceanic and Atmoshpheric Administration. The Foundation receives the grants, and the staff report to both Reserve Manager Becky Christensen and ESF Executive Director Mark Silberstein.
Other positions at the Reserve are funded by the California Department of Fish and Game, which makes the Reserve a federal-state partnership, and makes ESF a third party to this complicated arrangement.

It is complicated because that’s what it took to get things done. The shared history of ESF and the Reserve is full of programs that started with the Foundation receiving federal money to develop Reserve programs – some of which later became state programs. Twenty years ago the volunteer program, teacher training program, and research and monitoring programs all began as EFS projects and are now Reserve programs. It wasn’t an accident, it was planned that way.

The whole point of partnership is to accomplish more together than is possible separately. Our twenty-year partnership with the Reserve is the foundation upon which both organizations are built – and together we have been able to make truly remarkable progress towards our shared goal of protecting Elkhorn Slough

Report: Annual Member Walk, 2004 

More than 60 members joined ESF staff and Board members on our Second Annual Spring Walk on the Brothers Ranch. They took a two mile walk through fields dotted with wild iris and poppies and got a bird’s eye view of protected lands from a knoll at the center of the property. Across a ridge to the west is Elkhorn Slough. The ridge line that runs north and south contains a thousand acres ESF has protected. The lands along this ridge drain to the east into Carneros Creek, which provides 70 percent of the slough’s fresh water.


ESF members gathered on the knoll at Brothers Ranch,
where they enjoyed panoramic views of the watershed.

Executive Director Mark Silberstein explains the Foundation’s land strategy: “We are piecing together a crescent of protected land that stretches from Long Valley, along this ridge, down to the north end of the slough.” Protecting this land is vital to the health of the slough, Silberstein says, “because what we do on the land affects what happens in the water.”


Some members carried home armloads
of fresh flowers, which they picked
at a fallow field on the property.

ESF’s 22nd Annual Celebration will take place on June 26th, from 10 a.m. to 1 p.m. at the Elkhorn Slough Reserve. Last year the celebration was held away from the Reserve for the first time, at the Porter Ranch. We are returning to the Reserve this year, both because repairs are being made on the historic Porter house and to underline the Foundation’s support for the Reserve as it faces unprecedented budget cuts.

ESF Forms Legacy Circle
"A statement of values you hold dear."
(archive: Tidal Exchange summer 2004, Elkhorn Slough Foundation)

Elkhorn Slough has been blessed by the love and generosity of many people during the past 22 years. People who worked to halt plans for heavy industry and development, who helped create the Elkhorn Slough Reserve and the Elkhorn Slough Foundation, and who have given time and treasure, including family lands, to protect this special place forever.

Among those who have given to provide a legacy of protected land are five people who left bequests to the Elkhorn Slough Foundation. In our early years, our first bequest was a gift from Andrew Blomquist. That generous gift literally helped jumpstart our fledgling organization. Since then we have received bequests from Zoe Ann Orr Marcus, Bernice Porter, Burrel Leonard, and Elsie Triebig. We are deeply honored to be entrusted with their faith in our stewardship of the slough they loved. Their generous bequests were placed in the Foundation’s permanent endowment – funds set aside for the perpetual stewardship of Elkhorn Slough.

They left a legacy by becoming our partners in protecting Elkhorn Slough – and we honor them now by forming the Legacy Circle. Legacy Circle members are those who wish to make a lasting gift to protect Elkhorn Slough. These include gifts through wills, retirement plans, and insurance policies, as well as life-income and other deferred gifts.


“These gifts are a true legacy – they will shape the future beyond our lives,” says ESF Executive Director Mark Silberstein. “It is also a personal statement about the values you hold dear.” By joining the Legacy Circle, even if you chose to remain anonymous, you also encourage those you leave behind to consider their own legacies. The gifts from  our Legacy Circle will be placed in the Foundation’s Permanent Endowment. ESF currently has $2.9 million in its endowment and a long-term goal of building that to $10 million.

The first members of the Legacy Circle have chosen to remain anonymous. Two members of the Board of Directors and one staff member have become founding members of the Legacy Circle by including ESF in their estate plans. Two of these founding members have included ESF in their Wills. The third has chosen to include ESF as part of a Charitable Gift Annuity, one of many ways you may include ESF in your estate planning.

Estate planning can be intimidating, and ESF has arranged to provide free assistance through the Planned Giving Center of the Community Foundation of Santa Cruz County.

To find out more about the Elkhorn Slough Legacy Circle, please contact the Elkhorn Slough Foundation at 831-728-5939.

If you have already provided for the protection of Elkhorn Slough in your Will or estate plan, please let us know. We want to express our gratitude and welcome you to the Legacy Circle.

New in the Slough

Volunteer Shirley Murphy made a significant sighting in April when she spotted a rare visitor to the slough, a Yellow-billed Loon at Kirby Park.

This was just the30th sighting of this species in Monterey County in the last 35 years. Congratulations, Shirley!



The Cliff Swallows are once again busy building nests in the eaves of the garage building, among other places.
