Keep (the) Santa Cruz (Sandhills) Weird

17 04 2012

I’ve heard that Santa Cruz might be weird. I live in the redwoods above the city and maybe it’s a little strange here too. Sunset Magazine called Boulder Creek, just up the road, “absurdly rural.” In a search for the absurd, I considered visiting the nearby Bigfoot Museum to see if I could scare up a Sasquatch but turned instead to the park in my backyard, Quail Hollow Ranch County Park.

Since first visited the park, I’ve been intrigued by signs along the trail that say ” Sensitive Area Closed”. What are they hiding back there, behind the big shadowy arms of the live oaks?

This weekend, I found out. The Fish and Wildlife Service owns the property and there’s a good reason we can’t just go tramping around on it—and it has nothing to do with protecting Bigfoot’s habitat. Behind the signs is rare ecosystem harboring the true weirdos of Santa Cruz County: four plant species, a grasshopper, a beetle and a kangaroo rat that live nowhere else in the world.

The plants live for two or three years, but only produce flowers once. If the flowers are chomped off, the plant misses out on reproducing. Photo by SJK.

The Santa Cruz sandhills are so fragile that only 60 people are allowed to visit this particular parcel each year, 15 at a time, during Sundays in April. The perilously rare plants that grow there thrive in sandy soil free of competition from other species. And they grow right in the middle of the trail. If you walk on the trail you inevitably STEP ON A FEDERALLY ENDANGERED SPECIES. During last Sunday’s tour I was caught between the perverse thrill of having permission to accidentally trammel rare plants and the horror of doing so.

At the

beginning of the walk, our guide Shane, a systems engineer with a passion for geology and botany, pulled out some fossils to demonstrate the origins of the mountaintop beach in our backyard. He presented us with sand dollars, which are found in the 15 million-year-old silica soils only a short distance from redwood forests.

The coarse texture of the sand and the way nutrients and water slip through it fostered the evolution of the rare collection of heat, sun and drought-adapted plants a

nd animals that live there today. Since the early 1900s that sand has also been attractive for many industrial uses from making bottles, and now optics and silicon wafers. There’s an active sand quarry just across the street from Quail Hollow and six have been active in the area at different times.

The sandhills habitat has been destroyed, degraded and fragmented by mining but also by residential developments like the one I live in, vineyards, orchards and recreation. During the walk, Shane credited Jodi McGraw for assembling much of what people know about the sandhills as a UC Berkeley doctoral student. Her website about the sandhills says that there were about 6,000 acres of the naturally rare ecosystem and about 60 percent remains today. However, most of that land is not protected.

Now, when I climb a hill around my house and look out on mountains carpeted with green, I see the white sandy patches peeking through and think they are some of the most special things in my absurdly rural neighborhood (though the neon lumberjack is a close second). I came expecting to be enamored by redwoods but I also found the Santa Cruz Wallflower and the Ben Lomond Spineflower. Thank goodness for the weirdos.

In California, these Ponderosa Pines usually grow above 3000 feet in the Sierra Nevadas. In Santa Cruz county they are a low elevation oddity where they survive in the sandhills.

Less Smoke, More Fire

I grew up near a fortress built during the French and Indian War and used to love historical reenacting, but I eventually quit. In the eyes of dominant reenacting culture, period-correct portrayal of a frontier woman meant that my male friends would be throwing tomahawks and shooting muzzleloaders, and I’d be mending bodices and cooking over an open fire.

While I had the luxury of eschewing the cooking technology of the colonial period, almost half of world’s families still prepare their meals over open flame. And just as in early America, men are often out and about, while women and young children stay in the home where they continually inhale smoke.

This October, a Science paper from authors at the National Institutes of Health (NIH) named home pollution from open cooking fires the world’s leading cause of environmental death. Killing nearly 2 million people annually, indoor air pollution is more deadly than malaria, according to the World Health Organization. Most of the deaths come from acute lower respiratory infections in children under five and adult deaths from chronic obstructive pulmonary disease, which includes chronic bronchitis and emphysema.

I’ve recently become more aware of this issue because I’m writing a story about the Berkeley-based Darfur Stoves Project. Just after I started talking to people involved with the Darfur Stoves Project, I interviewed Bill Toone, the executive director of the San Diego-based ECOLIFE Foundation, about monarch butterflies. Both organizations distribute fuel-efficient cooking stoves in ways that are culturally specific, address the extreme logistical challenges of distributing a new technologies in poor countries, and attempt to create market demand for the stoves. The NIH authors list all of those things as barriers to stove adoption by families.

These projects demonstrate how food—and its preparation—directly touch individual quality of life, but then ripple into our local environments and, in the case of carbon emissions, the global environment.

As Toone said: “This is one of those wonderful crossover spots where we can help the environment, help a family and help ourselves in the sense that these cooking practices have an impact on our climate.

Since 2004, Toone and ECOLIFE have been working with communities in and near Central Mexico’s Monarch Butterfly Biosphere Reserve to distribute fuel-efficient cooking stoves. Deforestation over the decades–both by illegal logging cartels and locals, who need firewood for cooking—has fragmented the butterflies’ unique Oyamel fir habitat and put the migration at risk. ECOLIFE recognized that communities could reduce pressure on the habitat that they share with the butterfly by using less firewood to prepare their meals.

Toone’s approach to biological conservation comes from his conviction that people need to have adequate food, water and shelter before they can care for other things. “The most effective way we’re going to enact conservation on the planet, is that conservation is how we ensure our healthy survival into the future,” said Toone. “It’s really about us.”

When ECOLIFE tried to save money by removing the tile indicating that the Lorena cookstove is a friend of the butterflies, new stove users wondered what happened to the tile, and ECOLIFE restored the important symbol of the community's connection to the environment.

The Darfur Stoves Project is another stoves group working for human and environmental health. In 2006, the U.S. Agency for International Development approached Ashok Gadgil, a

physicist at Lawrence Berkeley National Laboratories, to help because militiamen were raping Darfuri women as they left refugee camps to search for firewood. A fuel-efficient stove would cut down on wood-gathering trips and women’s exposure to violence.

The stove that Gadgil and his team developed is the product of a long, iterative process between engineering and culture. The stove has been successful because it incorporated many design suggestions from Darfuri women. Now that there are few trees left to gather around the refugee camps, many women buy firewood rather than collect it, and the stove saves them money and time.

Andree Sosler, the executive director of the Darfur Stoves Project, told me in an interview that will appear elsewhere, about their most recent work in marketing the stoves and providing microloans so that women may purchase them. Like the NIH paper, she emphasized the importance of developing a market for stoves because it helps make the product more consumer-driven and sustains its distribution.

Though Toone is a conservation biologist who once worked on the California condor reintroduction, and Ashok Gadgil is a physicist and engineer, I heard a similar refrain from both of them. They weren’t satisfied with just working with animals or making gadgets, they wanted to see real changes in the quality of life of individuals.

Gadgil, a master of developing technology for people who are often overlooked by traditional research and development, summed up his motivations in an interview earlier this fall: “How can we say at the end of the day we made the world a little better. Do you say: ‘I want to publish one more paper’? No!”

Part of the Problem

It took me a long time to learn that I have a touch of road rage. The first time my husband watched me come slightly unhinged in gridlock, he only had one thing to say: “If you’re complaining, you’re part of the problem.”

Now that I’m spending a year as a California road warrior, it’s a mantra that slaps me with perspective whenever traffic slows to a crawl.

It’s also something that I’ve been thinking about since I fell for the United Nations’ marketing ploy surrounding today’s demographic holiday.

World population is somewhere around 7 billion: “If you’re complaining, you’re part of the problem.”

When I’m the sole person in a five-passenger car, I’m definitely part of the problem. It doesn’t take long for me to redirect my road rage inward.

The rectangle of environmental damage

Last week, I interviewed biologist Paul Ehrlich as part of my intern duties at the Stanford News Service. Ehrlich, the author of the controversial 1968 book, The Population Bomb, described a simple way to think about the entangled issues of population growth and consumption:

How do you respond to the statement that we should focus on overconsumption, not population growth?

Ehrlich: Most of humanity’s environmental problems trace to too much total consumption, but that consumption is a product of population size and per-capita consumption. Population and consumption are no more separable in producing environmental damage than the length and width of a rectangle can be separated in producing its area – both are equally important.

The next time I find myself trapped in an argument about which one matters more, I’m going to invoke geometry.

Both population and per-capita consumption are equally important, but our contribution to population is decided for us when we’re born, and we all need food, water and shelter. But I also seem to think that I need an iPhone, a Subaru, coffee and a hot shower. Need, maybe not, but that’s what I’m choosing.

Thank you, California

In addition to all of my consumption, I just became one more body in the most populous U.S. state. Thank you California, for your fresh agricultural products and tap water, I’m enjoying your resources.

In The Population Bomb Ehrlich warned of threats to food security, the availability of and access to enough food to live a productive life free from hunger or starvation. Many of his most dire and specific predictions have not come to pass, but we’ve been innovating ways to increase food production since the book was published; yet people generally agree that the current level of hunger in the world is still unacceptable.

California is an example of how we’ve engineered more food out of the land during the past century. It also supplies the U.S. with half of its fruits, vegetables, and nuts, making it an important part of the food system in our neck of the globe.

I recently stopped along I-5 to take in some of California’s extensive plumbing that makes it all possible. The roadside attraction was the Dos Amigos Pumping Plant, part of the California State Water Project (SWP). The pump lifts water in the California Aqueduct 114 feet, so it can flow by gravity 164 miles to the next pumping plant.

The SWP delivers water to two-thirds of the state’s population, with 70 percent going to urban users and 30 percent going to agriculture, according to the California Department of Food and Agriculture. Coincidentally, many initial phases of the project were completed in the years surrounding publication of The Population Bomb.

Having read Cadillac Desert, Marc Reisner’s 1986 opus on Western U.S. water development and sustainability (or lack thereof), seeing the California Aqueduct was like spotting a celebrity. Nothing drives home how we bend natural resources to our will like watching water flow languidly through a concrete conduit, on a journey hundreds of miles through an arid landscape.

I imagined how the water in the California Aqueduct started in the Sierra Nevada, much of it as snow, and how some of it would eventually reach Southern California. To make the journey, it is pumped nearly 2000 feet over the Tehachapi Mountains that divide the San Joaquin Valley and the Mojave Desert.

California’s water system has been described as a Rube Goldberg apparatus, which is not a cliché in this case. Before he became a cartoonist, Goldberg was a sewer engineer in San Francisco.

A paper, “Reclaiming freshwater sustainability in the Cadillac Desert”, published last year, found that “Reisner’s incisive journalism led him to the same conclusions as those rendered by copious data, modern scientific tools, and the application of a more genuine scientific method.”

Sustainability, according to the authors is defined as allocation of streamflow “to people farms and ecosystems.” They discuss issues that I have not mentioned here such as salination and impacts on biodiversity and fisheries. They mention, but do not analyze, climate change pressures on freshwater.

What would Reisner say about water in a world with 7 billion people? Sadly, we’ll never know because he was lost to cancer over a decade ago, at age 51. But an interview with Reisner, from 2000, in the now defunct magazine, California Wild, will let me give him the last word:

CW: The state’s population is projected to grow another 30 percent by 2020. If there’s enough water to fill California with people from border to border, is population growth a big problem for California?

MR: For California and the world. People ask me “What is the greatest environmental problem?” Some people think it’s water, and I say, “No. It’s population growth, by far.” It eclipses the next five most significant environmental problems combined, and in California it’s not much different.

This ending doesn’t make thinking about our roles on a planet of 7 billion any easier, but I’ll be considering how I contribute to the area of our resource sustainability rectangle, globally and in California.
