California state parks do more than provide public recreation

California state parks do more than provide public recreation

by Betsy Herbert, Earth Matters

published in the Santa Cruz Sentinel 8/17/17

Have you noticed all the mountain bikes strapped on cars traveling over Highway 17, especially on weekends? Demand for biking and other forms of recreation in the public spaces of Santa Cruz County is steadily increasing and much of that demand is coming from “over the hill” in the San Francisco Bay Area. Apparently, people increasingly need to escape from the stress of living in Silicon Valley.

At the same time, California State Parks has cut way back on acquiring new parklands in Santa Cruz County and throughout the state, following a complete reorganization of state parks beginning in 2013.

As demand steadily increases for recreation, sometimes people forget that state parks — as well as county and city parks and other public spaces — were originally set aside to do more than provide trails for public recreation. They were also established as natural areas to preserve habitat for other lifeforms and to ensure that natural processes — part of our planet’s life support system — function properly.

Is wilderness real? Is it worth restoring?

Is wilderness real? Is it worth restoring?

One evening last fall I nearly had a panic attack as I read the now famous 2003 article, “Are You Living in a Computer Simulation?” by Nick Bostrom, a Swedish philosopher at the University of Oxford. Bostrom’s theory has convinced many physicists and futuristic thinkers like Elon Musk that the natural world — the Universe — is actually a computer simulation created by some advanced post-human civilization. I’m not exactly a sci-fi aficionado and I had to force myself to watch “The Matrix,” but Bostrom made a strong, logical argument that for a brief moment shook my life-long belief that nature is the baseline for everything else that exists.

As an environmentalist, I’ve always held to the notion held by deep ecologists that wild nature, as it evolved through the eons, needs to be preserved as the foundation for life on the planet. Wilderness areas (Earth’s least disturbed places) are a priceless storehouse of our planet’s biodiversity. We need to protect wilderness — or else humans, along with other species that we share the planet with — will perish.

Super Bloom: On the hunt for wildflowers in Anza-Borrego and Joshua Tree

Super Bloom: On the hunt for wildflowers in Anza-Borrego and Joshua Tree

by Betsy Herbert, features@santacruzsentinel.com

published in the Santa Cruz Sentinel 03/30/17

It was March 14. For weeks California State Park botanists had been predicting a “super bloom” of wildflowers — the best in twenty years — to peak across southern California deserts sometime in the middle of March, and the best would be in Anza-Borrego Desert State Park, east of San Diego. After record winter rains, Anza-Borrego was already experiencing 80 to 90 degree temperatures — perfect conditions for a super bloom. I’ve lived in California most of my life and missed these gorgeous blooms in the past. This time I was determined to witness the show.

I set out in my hybrid SUV from Santa Cruz to hike and photograph in Anza-Borrego and then head northeast to Joshua Tree National Park, where I could expect to see those signature Joshua trees in full bloom.

Conservation group’s winning strategy to protect island communities

Conservation group’s winning strategy to protect island communities

by Betsy Herbert, Earth Matters

published in the Santa Cruz Sentinel 3/16/2017

Seacology, a Berkeley-based non-profit, got its start in 1990 when the island of Samoa’s government ordered the remote village of Falealupo to either build a new school house or lose its state-funded teachers. Desperate to continue their children’s educations, the cash-strapped community saw only one way out: Sell the logging rights to the 30,000-acre ancestral rainforest surrounding the village.

It just so happened that Dr. Paul Cox, an American ethnobotanist, was conducting field research in that same rainforest when he learned of the villagers’ dilemma. Shortly afterwards, Cox made a proposal to Falealupo’s leaders: If he could raise the money to build the new school, would the village agree to forever protect its surrounding forest?

Turkey vultures soar above in clear blue skies as I write from a hotel lobby on one of the 2,500 islands in the Jardines del Rey Archipelago off the north coast of Cuba. It’s day 13 of a 16-day tour focused on Cuba’s natural areas.

Our small group has been waiting here four hours to check in. Hotels in Cuba — even those billed as “four star” — seem completely overwhelmed by the booming influx of tourists from all over the world. Plumbing often leaks, Wi-Fi is sporadic at best, lights flicker, toilet seats are commonly missing, and towel racks dangle from the walls. But never mind, the music is infectious, the beer and rum flow freely, and the Cuban people are relaxed and friendly.

Who could imagine that the Cotoni-Coast Dairies property — once proposed by PG&E as the site of a nuclear power plant — would eventually become a national monument? But it’s true. On Jan. 12, President Barack Obama granted national monument status to this 5,875-acre property on Santa Cruz County’s North Coast.

Unquestionably, this iconic landscape is truly worthy of monument status ... for its scenic beauty and natural resources and as a tribute to the dramatic history of the land and the people who have dedicated themselves to protecting it.

Trees can talk — can humans learn to hear them?

by Betsy Herbert, Earth Matters

published in the Santa Cruz Sentinel 8/19/2016

I just watched a brilliant TED Talk by Canadian forest ecologist Suzanne Simard, explaining how trees talk to each other through vast underground networks of roots and fungus filaments called mycorrhizae. Simard explains that while trees don’t have brains or vocal chords, they communicate through these biological networks to — among other things — recognize and nurture their offspring and share resources with other trees in distress.

“It might remind you of a sort of intelligence,” she says.

She describes her 30 years of experiments in forests of the Pacific Northwest — research demonstrating that Douglas fir and paper birch trees communicate through these natural networks. These two symbiotic tree species help each other out by nutrient sharing during different times of the year.

In another experiment, she mapped forest underground networks to show how the biggest, busiest nodes cluster under the big “mother trees,” which send carbon and other nutrients through the network to their offspring trees.

Scientists have known about the fungus/plant root relationship since 1885, when the King of Prussia commissioned A. B. Frank to investigate cultivating truffles. While Frank didn’t succeed, he described the presence of mycorrhizae and coined the word, which means fungus-root.

Today, mycorrhizal networks are recognized as the modus operandi of more than 85 percent of plants in nature, including Sequoia sempervirens and other plants in the redwood forest ecosystem.

Since the 1990s, scientists have recognized that these vast mycorrhizal networks are fundamental to building soils and sustaining healthy forests. Mycorrhizal networks increase the supply of nutrients to trees and understory plants, provide protection from parasites and nematodes, stimulate tree growth, facilitate water uptake and increase carbon sequestration in soils.

At first I wasn’t convinced by Simard that trees talk. As a longtime forest protection advocate, I used to wear a button saying, “If trees could scream ... ,” alluding to the fact that trees can’t speak for themselves in the face of human onslaught. Simard made me do a double take. Maybe trees can talk, but we simply aren’t listening.

As author Michael Pollan said in the New Yorker in 2013, “Plants speak in a chemical vocabulary we can’t directly perceive or comprehend,” and the conversation takes place through these natural networks.

Pollan’s article summarizes an ongoing scientific debate, in which many scientists balk at the concept that plants possess intelligence, historically assumed to be the exclusive domain of the animal kingdom. The argument goes something like this: Animals have neurons and brains, which are the seat of intelligence. Since plants don’t have neurons or brains, they can’t be intelligent.

The argument goes something like this: Animals have neurons and brains, which are the seat of intelligence. Since plants don’t have neurons or brains, they can’t be intelligent.

Other scientists argue that it depends on how one defines intelligence, a longstanding topic of philosophical debate. Advocates of plant intelligence like Italian botanist Stefano Mancuso define intelligence as “the ability to solve problems.” Given that definition, it seems undeniable to me that trees possess intelligence. Simard and other scientists have shown that trees communicate.

Is there something the trees are trying to tell us?

Simard implies that humans should listen carefully to what the trees are saying, particularly the intensively clear-cut forests of the Pacific Northwest, where she has done her research. Forests are complex systems with interconnected networks that allow trees to communicate, making the forest resilient.

But the forest is still vulnerable to things like bark beetles, high-grade logging and clear-cut logging. All these things destroy the hub trees, which, Simard says, can be seen as rivets in an airplane. Remove one or two and the plane still flies, “but if you take out one too many, or maybe that one holding on the wings, and the whole system collapses.”

A glimpse of Galápagos life before man intervened

by Betsy Herbert, Earth Matters

published in the Santa Cruz Sentinel 4/28/16

In month 10 of my yearlong trip around the world, I flew from Quito, Ecuador, 600 miles west to the tiny Pacific island of Baltra in the Galápagos Islands. From Baltra, I took a spectacular cruise on a 75-foot catamaran, exploring six of the islands.

On this eight-day voyage, I was thrilled by the unique natural beauty of this volcanic archipelago. I also learned about some egregious human impacts that have taken a big toll here and the extraordinary efforts underway to reverse them.

The Galápagos, of course, are famed as the site of Charles Darwin’s epic 1835 journey on Captain Robert Fitzroy’s HMS Beagle. The strange wildlife endemic to this place — most notably Galapágos finches and giant tortoises — started Darwin’s wheels turning about natural selection and led to his eventual publication of “The Origin of Species.”

My longtime fascination with the Galápagos is shared with some 150,000 tourists who visit each year. Since 1959, most of the entire land mass of the Galápagos Islands was designated as a national park and as a World Heritage Site protected area. So, tourism is regulated, especially extended cruises, where trips to each island are professionally guided and well-coordinated.

Most of the islands still seem pristine and are incredibly beautiful. We hiked across huge spreads of black Pahoe-Hoe lava dotted with cacti. We got up close to some of the rarest birds in the world, including red-footed boobies, Galápagos finches and flightless cormorants. We plodded alongside huge Galápagos giant tortoises and land iguanas in the wild.

We snorkeled with sea lions, penguins, and Pacific green turtles and walked among hundreds of marine iguanas piled up on the beach like stacks of pancakes.

But, as our guide carefully explained, the monumental efforts now in place to conserve biodiversity on the Galápagos got a late start.

When the first Europeans landed in the Galápagos in 1535, there were no humans living there. The islands’ remoteness, inhospitable terrain and scarcity of water would have made permanent settlement very difficult indeed.

In the 1700s, the Galápagos became a frequent port for whalers, because of the islands’ proximity to prime sperm whale habitat.

In the 1800s, whalers aggressively sought out the slow-moving Galápagos giant tortoise as a food source. Because these reptiles can survive for months without food or water, they could be easily be kept alive on board ship before ending up in the stew pot.

Whalers took more than 100,000 giant tortoises from the islands. As tortoise populations plummeted, whalers looked for a new food source. They released a few goats to one of the islands, intending to return periodically to hunt them.

But the goats, without any natural predators, quickly reached a population of 100,000 that devastated the island’s native flora needed by the tortoises — another step down the path to extinction.

Similar stories have played out throughout the Galápagos with goats, dogs, pigs — and lately, a fly maggot — all continuously being imported by people and wreaking havoc on native ecosystems.

In 1959, when the Galápagos Islands was declared a World Heritage site, UNESCO partnered with the Charles Darwin Foundation to fund research, conservation, and education strategies to protect endemic species of the islands.

Since then, the Galápagos Islands have attracted top conservation scientists and witnessed some of the most extraordinary invasive species eradication projects anywhere. For example, Project Isabela, overseen by Galápagos National Park Service and the Charles Darwin Foundation, has eradicated feral goats and pigs from Santiago and Isabela islands.

While tourist dollars help fund conservation efforts, tourists also unwittingly import new invasive species every year. If you go, be prepared to have your baggage inspected!

Flying like a bird to support forest restoration

Contributed This zip-wire tour aims to educate visitors on the disappearing birds of New Zealand.

Up 120 feet in the forest canopy last week, I launched off a platform surrounding a towering 1,000-year-old kauri tree in Dansey Forest, Roturua, New Zealand. Holding onto my harness straps, I pushed off with my feet, surrendered my weight to the zipline, and went flying 720 feet through the treetops. About halfway through the flight, I let go of the harness, leaned back and spread out my arms. Exhilarating!

I had a little help of course. I was part of a group of 10 zipliners led by guides Scott and Kathy, locals employed by nonprofit Rotorua Canopy Tours.

During our three-hour adventure, we whizzed over .75 miles of ziplines, traversed three swinging bridges, and hung out on five tree platforms, all the while learning about the plight of New Zealand’s native birds and the group’s ongoing efforts to help them survive. By the time the tour ended, I was glad to know that a portion of my ticket price would be invested in supporting these efforts.

Kathy explained that 51 bird species endemic to New Zealand including the moa and other flightless birds are now extinct, while many other species are in decline. Because New Zealand birds evolved in isolation when there were no existing land mammals to prey on them, they never developed natural defenses needed to fend off introduced mammals.

While humans hunted the moa and other large birds, the nail in the coffin for many extinct bird species was the introduction of exotic mammals such as the possum, rat and stoat (a type of weasel). Fur traders introduced the possum because of its value in pelts, the rat came into New Zealand as a stowaway on ships, and the stoat was introduced in hopes that it would prey on rabbits, which were themselves introduced earlier with prolifically tragic results.

Some of the favorite foods of the possum are the new growth on New Zealand’s native trees and the eggs of its native birds. There are now some 30 million possums in New Zealand, so their impact is astounding.

The rat also likes to eat native birds, as well as the seeds and fruits of the native trees, inhibiting their ability to propagate. Perhaps worst of all is the stoat; once introduced to New Zealand, the stoat lost its taste for rabbits and instead took to preying on native birds, especially the kiwi, New Zealand’s national icon.

As all of these exotic mammals were being introduced, New Zealand’s native forests were being decimated by logging and slowly replaced with introduced tree species like Monterey pine, which is now the country’s leading commercial timber tree. As native forests were replaced with exotic tree plantations or converted to farmland, the habitat of New Zealand’s native birds took a huge hit.

What could be done to turn this around? The founders of Rotorua Canopy Tours, James Fitzgerald and Andrew Blackford, decided to create a successful eco-tourism business to support the active trapping and killing of possums, rats and stoats on this 1,235 acre Dansey Forest to bring back native bird populations. The group joined into a partnership with the New Zealand Department of Conservation, which owns the land.

Their efforts have paid off. After testing different kinds of traps, the company now has installed more than 1,000 instant kill and humane traps in the forest. To date, 10 percent of the Dansey Forest is free from these exotic predators. Zipliners can now hear the birdsongs of the native North Island robin, the tomtit, tui, and the kaka, which are returning to the forest.

Thailand’s efforts to help endangered Asian elephant

After camping among wild African elephants in the Serengeti National Park, Tanzania, last September, I greatly anticipated visiting wild Asian elephants in Thailand this month. But when I arrived, I found that finding wild elephants in this country is a little tricky.

Like their larger African cousins, Asian elephants are a highly endangered species. According to the the American Museum of Natural History, hundreds of thousands of elephants roamed Asia until only about 100 years ago. Today, they have been wiped out from large areas of India, Southeast Asia and China, leaving fewer than 50,000.

I found three great places to visit Asian elephants in northern Thailand, all about an hour’s drive from the city of Chang Mai. Trouble is, the elephants in these places are not exactly wild. That’s because 95 percent of Thailand’s elephants are living in captivity, and nobody really knows how many wild elephants are left.

A friend and I drove to the Thai Elephant Conservation Center in the densely forested hills near Lampang. The TECC is a government-sponsored elephant camp that houses more than 50 Asian elephants (including six of the Thai Royal family’s white elephants). TECC seeks to educate tourists about the plight of elephants and to raise money for their conservation.

We watched the elephants bathe and frolic with their trainers in the creek flowing through the TECC grounds — truly a highlight of this trip!

After bathing, about a dozen elephants were led to a ring where they performed before an audience of some 200 tourists. They bowed as they were introduced one by one and did some cute tricks like removing the hats of their trainers. Later on, the elephants demonstrated how in the past, they were used to drag enormous logs out of the forest and stack them with their trunks. Elephants are no longer used by the timber industry because the Thai government banned logging in natural forests throughout the country in 1989.

At the beginning of the 20th century, the timber industry greatly increased logging of native teak and other tropical hardwoods in Thailand for export. Loggers began capturing and training large numbers of wild elephants to haul and stack logs. At the same time, this extensive logging destroyed much of the elephants’ natural forest habitat.

In 1988, Thailand experienced its worst flooding in 300 years, due to unsustainable logging and extensive forest clearing to create more agricultural land. So, in 1989 the Thai government banned logging in all natural forests in the country.

This ban put loggers as well as elephants out of work. Maybe not such a bad thing if the elephants could return to their natural habitats, but there was no place left for them to go.

In 1997, the Thai government founded the Thailand Elephant Conservation Center to help care for these “unemployed” elephants. The center advocates using elephants in tourism to provide income to care for them. Tourists can pay to ride the elephants after they pay to watch them perform.

Another organization, the Elephant Nature Park (ENP) is operated as a nonprofit to provide a natural sanctuary to treat and protect elephants from the sometimes harsh treatment in tourism as well as logging. They seek to re-introduce rescued elephants into the wild.

 Yes, elephant prosthetics are important as many Asian elephants have been injured by landminds.

Yes, elephant prosthetics are important as many Asian elephants have been injured by landminds.

Finally, the Thai Elephant Hospital, sponsored by Friends of the Asian Elephant, rescues and treats injured elephants. When we visited, we were introduced to Motala, a 50-year-old female elephant who was badly injured, like many others, by a land mine as she was working in the forest. The hospital manufactures prosthetic devices to fit these elephants like Motala to enable them to walk.

Bhutan: Where environment is key to ‘Gross National Happiness’

by Betsy Herbert, Earth Matters column

published in the Santa Cruz Sentinel 10/22/15

 Bhutan opened its doors to tourism only 40 years ago, and it still requires every tourist to be part of a certified tour group. The government of Bhutan wants to avoid the environmental degradation that Nepal has suffered over the past 50 years due to tourism.

Bhutan opened its doors to tourism only 40 years ago, and it still requires every tourist to be part of a certified tour group. The government of Bhutan wants to avoid the environmental degradation that Nepal has suffered over the past 50 years due to tourism.

As our flight ascended above the thick blanket of smog over Kolkata on the east coast of India, I was excited to be heading north to the remote country of Bhutan, known for its ancient monasteries, multi-colored prayer flags and spectacular scenery.

In just 45 minutes, we would be making one of the world’s most thrilling descents into Bhutan’s international airport, nestled in the Paro Valley between soaring Himalayan peaks.

For years I had wanted to visit Bhutan because its government officially measures national progress by the “Gross National Happiness” of its people. This term was coined in 1971 by the king of Bhutan, but the concept has increasingly drawn global attention.

Unlike other indicators of national progress, Gross National Happiness is a scientifically constructed index that ascribes equal importance to noneconomic aspects of people’s well-being, such as education, health, environmental protection and cultural preservation. The concept is rooted in Bhutan’s history. According to the legal code of Bhutan, dated 1729, “If the Government cannot create happiness for its people, there is no purpose for the Government to exist.”

The Kingdom of Bhutan is a primarily Buddhist country whose population is around 770,000 (about 1/18th the size of the city of Kolkata). Tiny Bhutan is surrounded on three sides by India (population approaching 1.3 billion), while China (population 1.4 billion) borders it to the north.

After we made a flawless landing at the Paro airport we approached the main terminal, which at first it looked like a temple with its curved tiled roof, colorful hand-painted timber-framed windows and whitewashed walls.

As our small tour group made its way through immigration, we met our Bhutanese tour guide named Chen, who would — with grace and humor — treat us to some unforgettable experiences in Bhutan for the next week.

Bhutan, now a constitutional monarchy, opened its doors to tourism only 40 years ago, and it still requires every tourist to be part of a certified tour group. Chen said the government of Bhutan wants to avoid the environmental degradation that Nepal has suffered over the past 50 years due to tourism.

Bhutan’s Gross National Happiness index gives the natural world a central place in the making of public policy, and environmental protection is a core guiding principle in Bhutan’s constitution. As a result, Bhutan has pledged to remain carbon neutral. In 2015, Bhutan is a carbon sink, meaning it stores more carbon than it emits. This is partly because the country has pledged to keep at least 60 percent of its land forested. Currently, more than 70 percent is forested. Bhutan has banned export logging, so that most of its big trees remain standing in the forests, where they sequester carbon from the atmosphere.

 Bhutan’s happiness index is rooted in the country’s history. According to the legal code of Bhutan, dated 1729, ‘If the Government cannot create happiness for its people, there is no purpose for the Government to exist.’

Bhutan’s happiness index is rooted in the country’s history. According to the legal code of Bhutan, dated 1729, ‘If the Government cannot create happiness for its people, there is no purpose for the Government to exist.’

Still, Bhutan faces environmental challenges. Hydropower and tourism are Bhutan’s largest industries. The abundant water supply from glacial fed rivers from the steep slopes of the Himalayas create huge hydropower potential.

According to one source, (www.internationalrivers.org/blogs/328-5) some 24,000 megawatts of hydropower could be feasibly realized in Bhutan, though only about 1,360 MW have been developed to date. Most of these hydropower projects have been financed by India, which takes delivery of most of the electricity produced.

It's unclear how much Bhutan can develop its hydropower potential without causing significant harm to its river ecosystems. No doubt this issue could present a serious challenge to Bhutan’s commitment to environmental protection. During my visit, I photographed one large sign in a local village that expressed concern about the demise of the rare white-bellied heron as a result of hydropower development.

After a few days of fun and frolic at the Fringe Festival in Edinburgh, Scotland last week, I rented a car and set out on an eight-day foray through the Scottish Highlands. As an American, I did not take driving in Scotland lightly. It’s scary driving on the other side of the road and you have to muddle through “rotaries” to find your exit while remembering to yield to cars coming from the right. Scotland’s roads are narrow and often edged with high and unforgiving curbs. Stressful!

For me, hiking has always been a great way to relieve stress, so I decided to visit plenty of forests, rivers, and trees in Scotland. What a joy it was to see so much water! I started with a visit to a Scottish fish ladder at the dam in the town of Pitlochry. The ladder is designed to help salmon returning from the sea bypass the dam on their way back to their ancestral headwaters to spawn. Engineers have installed an electronic counter that keeps track of the fish that use the ladder each season. When I looked, the count was 3,760, but the season isn’t over yet.

No visit to Scotland would be complete without a visit to Loch Ness. My favorite view was from the ruins of Urquhart Castle, near Inverness.

I next set out to view some of Scotland’s oldest and biggest trees. First on the list was the Fortingall Yew, an ancient European yew (Taxus baccata) in the churchyard of the village of Fortingall in Perthshire. The yew is estimated to be anywhere between 1,500 and 5,000 years, so it may be the oldest tree in Britain. It’s difficult to ascertain its age because the tree has been cut back and burned repeatedly over the ages

On my way to the village, I stopped to visit Castle Menzies, a 16th century stone relic that has been thoughtfully restored. I learned from the exhibits inside that one of the Menzies clan who inhabited.the castle was the famous Scottish botanist Archibald Menzies, who traveled the world in the 1700s collecting plants. Menzies’ name is commemorated in the scientific names of several plants he discovered, including the Douglas fir (Pseudotsuga menziesii) and the Pacific madrone (Arbutus menziesii), trees which are very familiar to Californians. (David Douglas introduced the Douglas fir to Scotland from the Pacific Northwest in 1837).

The next ancient tree I visited was the legendary Birnam Oak, thought to be the last surviving tree of Birnam Wood, featured in Shakespeare’s Macbeth. The Birnam Oak grows, along with other very old giant trees, along the River Tay near the town of Dunkeld.

Though most of the forest land that I saw from the road was intensively managed timberland, there are also some beautiful protected areas that are part of the National Trust for Scotland.

One of them is the Hermitage, a woodland surrounding the river Braan and its spectacular Black Linn Waterfall. I took great pleasure in knowing that the path that I followed had been walked by Wordsworth, Queen Victoria, Mendelssohn and Turner. The path, which feels like the backdrop to a fairy tale, takes you into iconic stands of enormous Douglas firs, planted in the 1800s and 190

I ended my Scottish Highlands tour with a visit to Loch Lomond, the largest freshwater lake in Britain, and Ben Lomond, the peak that towers above it. In Santa Cruz County, our own Loch Lomond and Ben Lomond are named after these places, so this was indeed a meaningful way to end my tour.

Enjoying and protecting wild Croatia

by Betsy Herbert

published in the Santa Cruz Sentinel 06/20/2015

Last week I left the beautiful old city of Dubrovnik, saying goodbye to Croatia and to the 17 other hikers, bikers and kayakers I met during our two-week Sierra Club International outing, “Jewels of Croatia: Forests, Rivers and Islands.”

 The famous Plitvice National Park draws more than a million visitors a year.

The famous Plitvice National Park draws more than a million visitors a year.

Starting in the capital city of Zagreb, our group, led by two Croatian guides, would travel by van roughly north to south, stopping to experience the country’s vastly different landscapes. We would hike through alpine meadows of the Velebit Mountains, cycle through valleys graced with small towns and vineyards, kayak on crystalline rivers, and sail to some of the 1,200 islands along the coast of the Adriatic Sea.

Before we left Zagreb, a scientist named Mate Zec briefed us about the natural areas we were about to see. Zec is employed by Association Biom, a nonprofit based in Zagreb and affiliated with Birdlife International, a nonprofit that manages 6,000 natural areas in 47 countries.

Croatia is about the size of West Virginia. Some 25 percent of its land is arable farmland and about 40 percent is forested. Fifty percent of Croatia’s landmass is limestone karst. Riddled with caves and underground cavities, limestone karst stores and exudes enormous amounts of water in the form of abundant rivers and waterfalls. Croatia’s coastal areas have a Mediterranean climate with mild winters and hot and dry summers, while its mountains, the Dinaric Alps, have cold winters and hot summers.

 Karstic limestone in the Velebit Mountains show signs of long-ago erosion.

Karstic limestone in the Velebit Mountains show signs of long-ago erosion.

These different climates and landscapes have produced remarkable biodiversity in Croatia. The network of subterranean limestone caves host species of plants and animals that are found nowhere else in the world. Croatia’s forests and grasslands are home to many different species including brown bears, wolves and lynxes. But many of these species, especially the native lynx, are threatened.

According to Association Biom, 8.5 percent of Croatia’s land is designated as some type of protected area. There are both national parks and regional “nature parks,” which are managed differently. Admission tickets to the more popular parks provide an important source of income for park management. The famous Plitvice National Park, for example, draws more than a million visitors a year.

Tourism accounts for about 15 percent of Croatia’s GDP. Croatia’s population of 4.5 million has an average per capita income of $17,800. So, income from tourism is especially important.

But tourism can also create problems for natural areas. For example, Zec explains that a few “rich parks” with high numbers of tourists have no daily limits to the number of visitors. Later, when our group visited Plitvice National Park, we found that even prior to peak season, we had to move single-file along the trails, reminiscent of U.S. national parks like Yosemite at peak season.

Zec said that park management varies greatly throughout Croatia due to political influence. The result is that parks throughout the country have different levels of habitat protection, policies and investments in research.

Land-protection policies may be changing in Croatia, though, since Croatia joined the European Union (EU) in 2013. That’s because the EU has relatively high standards for protection of natural areas and endangered species that member countries must address.

Zec identified some threats to Croatia’s biodiversity on land outside of protected areas. These include increased development along the coast for tourism and increased construction of wind and hydro-power plants. While alternative energy projects help combat climate change, wind farms can spell death for migratory birds and dams can impact freshwater ecosystems.

Learning about Croatia’s natural areas enhanced our ensuing adventure. As we kayaked the wild rivers of Croatia and sailed the turquoise Adriatic Sea, we were newly inspired to help protect these natural gifts.

Redwood Champions Amid Drought and Climate Change

Redwood Champions Amid  Drought and Climate Change

by Betsy Herbert, Ph.D.

published in the Mountain Echo, newsletter of the Sempervirens Fund, Fall 2014

Redwoods are extraordinary. The more we learn about them, the more extraordinary they prove to be. We’ve known for a long time that California’s coast redwoods (Sequoia sempervirens) are the world’s tallest trees and among the longest-living. Scientists are now confirming that redwoods play an important role in the local water cycle and in achieving a healthy, stable climate.

By meticulously measuring redwoods, scientists are determining how fast they’re growing, storing carbon and capturing fog, and how they are responding to climate change. For example, a team of scientists is working on the “Redwoods and Climate Change Initiative” (RCCI), with support from Sempervirens Fund, to quantify how accelerating climate change is affecting California’s redwoods.

Logging: Santa Cruz Mountains protection threatened

Logging: Santa Cruz Mountains protection threatened

Santa Clara, San Mateo and Santa Cruz Counties' redwood forests, known as the Southern Subdistrict, are highly valued for their timber, wildlife habitat and carbon sequestration -- but also as places for people to live and enjoy the outdoors. Many mountain communities and the entire county of Santa Cruz also depend upon forested watersheds for their drinking water.
But a bill in the California Legislature would remove critical protections that counties in this region have relied on for decades.

Elderly Aptos couples envision preserving their giant redwoods

Elderly Aptos couples envision preserving their giant redwoods

The only way to get to Dan and Pat Miller’s house in Aptos is to walk across a 3-ft wide wooden bridge spanning the steep canyon above Mangels Creek. As I cross the bridge, I feel like I’m walking back in time into a fairy tale. The Millers’ house, built in 1931, is dwarfed by the five giant old redwood trees that encircle it.
