Everglades National Park

/ bigdiff / 4 Comments

The southern end of Florida is home to Everglades National Park, which is also a UNESCO Biosphere and a World Heritage Site. Since 1900, the area has been both protected and threatened, with political battles needed to protect bird plumage, to create the park, and to protect the large, diverse ecosystem here. Marjory Stoneman Douglas wrote a book to explain how the Shark Valley River Slough runs as a “river of grass” through the Everglades. When summer rains fill Lake Okeechobee, a sheet of water overflows the low bank and floods the flat grasslands, revitalizing fish eggs and a whole ecosystem. A cross Florida road called the Tamiami Trail prevented that flow, and a political battle was fought to restore it partially. The fresh water eventually sinks through the limestone, filling the Biscayne Aquifer to provide drinking water for Miami. There are also canals crisscrossing lower Florida, including here, and that’s where these two young alligators were hanging out. Alligator Alcatraz, a temporary migrant detention center, is in the Everglades ecosystem, but it’s not in the national park. Alligator Alcatraz is north of the Tamiami trail in Big Cypress National Preserve.

The park is 1.5 million acres, including the mangrove islands that form the southern end of Florida, before the Keys. The best place to see the mangroves is by boat, either from Everglades City west of Big Cypress or by driving to Flamingo. I took my family to the latter, and we saw a large crocodile near the dock, plus much more wildlife on a quick cruise in the “submerged wilderness” of Florida Bay. Personally, I wouldn’t kayak these waters, but many people do, camping on the Chickees or raised bits of ground where natives camped seasonally and for different purposes for centuries at least. There’s even a paddling waterway to go between Everglades City and Flamingo. Before the highway was built out to Key West, visitors commonly took a similar route by boat.

The work of environmental protection is never done. Burmese pythons entered the park in the 1970s—likely as discarded pets—, and now they’ve wiped out most of the native animals, threatening the Florida panther with extinction. I was disappointed to see the dramatic decline in wildlife evident from the Shark Valley Tower, since I first visited decades ago and even since I visited again with my family not so many years ago. And since last year, the state government is not allowed to mention climate change, global warming or sea level rise, but that obviously won’t do anything to prevent rising sea levels from submerging much of southern Florida, including most of Miami and almost 1/2 the park in the coming decades. Especially if the government refuses to take action, climate science clearly shows that the environment will only continue to worsen more rapidly.

Big Cypress National Preserve

In the bigger, more famous neighboring park in southern Florida, the paid guide assured me that the American alligator “is a solitary creature, you never see more than one or two together”. In Big Cypress, I counted 16 alligators in one puddle and 17 in the next. Unlike most other wildlife I try to photograph, the alligators don’t run away; they look you right in the eyes and even slowly move towards you. Some are easy to spot, but while I was counting, three more were sneaking up on me.

Most of the million acres in Big Cypress and its smaller partners are actually prairie habitat for the endangered Florida panther, but there was a devastating fire recently, in our rapidly heating world. I drove the loop road instead, looking for gators in the gullies, but I often found myself looking up at the various trees to look at the air flowers hanging on to trunks and branches. In the hardwood hammocks, you might see some tree snails. And I saw a lot of birds, especially wood storks and other large wading birds.

Coming from the Naples side, I stayed in Everglades City, which is tucked in between the Ten Thousand Islands, the Everglades western estuaries and mangrove islands, and Big Cypress. Before the highway was extended to Key West, many visitors took boats to Key West from Everglades City. They’re rebuilding the hurricane damaged visitor center there in the name of Marjorie Stoneman Douglas, who wrote the book, River of Grass, that led to the protection of 2.5 million acres of lower Florida. Fortunately, large commercial efforts to farm, graze and otherwise exploit the land had all failed, so the environmental coalition won. Carbon pollution raises sea levels, so the future is uncertain. But for now, this is a good place for adventure travel out into the mangroves.

Climate Consequences

The consequences of our carbon pollution provoke an instinctual reaction, but we must consider them rationally. Let’s clearly understand the cause, consider the consequences, and evaluate our options.

Humans have a history of damaging our environment, including driving many species to extinction, from the Wooly Mammoth to the Passenger Pigeon, last observed by Teddy Roosevelt. We have leached deadly chemicals into water supplies, released clouds of cyanide, bleached corals, created toxic fog and smog over cities, poisoned people with mercury, introduced microplastics into most living creatures, burned holes in the ozone, leaked radiation, made rivers burst into flames, filled oceans with garbage, and spilled oil, leaving dead zones. And that’s just pollution, excluding environments and species destroyed by development, drilling, farming, fishing, hunting, logging, mining, ranching, and war.

But our most continuous and consequential pollution is carbon. Especially since Drake’s Well began modern oil drilling, we have extracted fossil fuels of ancient forests that grew 300 million years ago and burned them into our atmosphere, changing our environment into something of which our species has zero survival experience. The last time we had this much carbon in our atmosphere was twice as long ago as when our most primitive ancestors split off from chimpanzees.

  • Heat has been increasing, contributing to fires and killing more people every year.
  • Droughts have been getting worse, contributing to fires and killing more people every year.
  • Glaciers and snowpack have been shrinking, contributing to late season fires and killing vulnerable species.
  • Storms have been getting worse, contributing to fires, floods and tornadoes, killing more people every year.
  • Sea levels have been rising, threatening to flood low lying cities and coasts.
  • Corals have been bleaching—dying en masse—and oceans have been acidifying, killing marine species.
  • Diseases have been increasing, killing more people and species every year.
  • Soil is becoming less healthy, due to erosion, salinization, loss of micro biodiversity and more.
  • Deforestation, melting permafrost and changing water chemistry are reducing carbon sinks and in many cases releasing carbon pollution, like methane, into the atmosphere at increasing rates.
  • Species are going extinct at an increasing rate.
  • Ecosystems are being damaged, where problems with one or more species affect other species, often in unforeseen ways.

These carbon pollution problems are deadly, unprecedented since humans evolved, are synergistic—meaning that they combine and multiply effects—and will affect everyone negatively, at least economically.

We have alternatives to fossil fuel that cause far less damage and risks to life on earth, especially solar and wind power. In many cases, these alternatives are also cheaper.

Hoping that someone will invent some unknown solution that’s cheap, effective and has no side effects is not rational, given how simple and cheap it is to burn carbon fuel. Carbon capture devices are expensive, especially at the scale needed to shrink total carbon in the atmosphere. Geoengineering is unproven, expensive, and will bring unexpected negative consequences. We do not have any inexpensive, reliable way to mitigate the damage of carbon pollution, apart from reducing carbon pollution.

Rationally, the choice to stop burning so much carbon and convert to renewable energy in order to avoid these ill effects is clear and simple. Dishonesty about the causes, effects, alternatives and consequences is part of the problem. Science, including economics, supports reducing carbon emissions before damage and costs worsen. History shows that violent conflicts arise when living conditions deteriorate and governments struggle to feed and house people.

Instinctually, our fear of death should motivate us to stop burning so much carbon. In future posts, I will discuss other ways of thinking about our climate crisis, but I suspect the problem may not simply be how we think. The basic problem may simply be that we aren’t thinking at all.

Ferries

My medium term goal is to visit all the parks in the lower 48 states in my electric car, and that necessarily includes taking an occasional car ferry. I would prefer never to take carbon burning transportation, but I’m neither going to risk my life nor break the law, nor encourage anyone else to do so. Some river roads, coastal highways and islands rely on ferries—such as in the Outer Banks or San Juan Islands above—, without practical alternatives. The only way to visit the Statue of Liberty or Alcatraz is to take the ferry.

My general rule is to arrive at each park by zero emission vehicle but to take park transport as needed to enjoy the park, like at Steamtown. Whenever I can, I encourage park employees to replace their old transport with solar powered electric boats, which would be perfect at Fort Matanzas. And the NPS is slowly converting its transportation to renewable, for example at Zion.

So when the park recommends taking a partner ferry to get to Governors Island, Isle Royale, Perry’s Monument, Boston Harbor Islands or Fire Island, I sit back and enjoy the ride. And I get more out of my visit, especially on narrated tours of wonderful places like the Apostle Islands, Pictured Rocks or Rainbow Bridge.

All Teddy Roosevelt Sites

The park service commemorates six parks for Teddy Roosevelt, from his childhood home in NYC, to the ranch in North Dakota where he mourned, to his family home on Oyster Bay, to the room where he was sworn in after an assassination, to the DC island that celebrates his legacy and to the monument that rightly places him among our greatest presidents. The carbon crisis threatens to end the environment Teddy Roosevelt saved for us, so he would want us to switch to electric vehicles to enjoy all his parks, as I did.

At least a dozen current National Parks began with Teddy Roosevelt protecting their land, besides his namesake park above. His friendship with John Muir inspired our entire national park system. We owe a debt that we can only repay by continuing his legacy of preservation for the future.

As President, Teddy Roosevelt protected 230 million acres for us in 20+ states, including national forests, rivers, preserves and more, such as around the beautiful San Luis Valley. He’s directly responsible for all the units listed below, plus others, as well as for signing the Antiquities Act by which presidents still designate national monuments.

“The civilized people of today look back with horror at their medieval ancestors who wantonly destroyed great works of art, or sat by slothfully by while they were destroyed.
We have passed that age, but we are, as a whole, still in that low state of civilization where we do not understand that it is also vandalism wantonly to destroy or to permit the destruction of what is beautiful in nature – whether it be a cliff, a forest, or a species of mammal or bird.
Here in the United States we turn our rivers and streams into sewers and dumping-grounds.
We pollute the air, we destroy forests and exterminate fishes, birds and mammals – not to speak of vulgarizing charming landscapes with hideous advertisements.
But at last it looks as if our people were awakening.
Above all we should realize that the effort toward this end is essentially a democratic movement!
Now there is a considerable body of opinion in favor of our keeping for our children’s children, as a priceless heritage, all the delicate beauty and all the burly majesty of the mightier forms of wildlife.
Surely our people do not understand, even yet, the rich heritage that is theirs!”

Teddy Roosevelt, 1913

Xochimilco

This is only half of a World Heritage Site, Mexico City, even though it’s on the outskirts. Frankly it’s status is controversial. To the extent that it preserves the long cultural history of floating gardens and canals, then it deserves global recognition. Unfortunately, it’s also known as a place to get drunk with friends over the weekend on one of the colorful boats above. And the city has encroached on the area, overbuilding, developing, squatting, polluting and diverting the water. So, it’s at risk. Really the damage was mostly due to the Spanish who drained the lake to build a new city over the old Aztec city, so this is one of the few places directly linked to the extensive ancient Aztec canoe and irrigation canals. A few parts are preserved, some are threatened and many are gone. Restoration is difficult and expensive, but worth it in my view.

Biospheres of the Rocky Mountains

/ bigdiff / Leave a comment

Biospheres are important ecological areas around the globe for protecting species diversity and for learning how to best sustain development ecologically, economically and socially. Science and solutions learned in each area are shared globally through the United Nations, and this is particularly important now that we face a global climate crisis. UNESCO currently recognizes three biospheres in the Rocky Mountain Region, and up to 2017, there were five more described below.

The Rocky Mountain Biosphere in Colorado roughly encompasses Rocky Mountain National Park and some of the Rocky Mountain Wilderness to the north. Some of the charismatic species in the biosphere are Bighorn Sheep, Elk, Mountain Lions, Pika and Snowshoe Hare. Scientists have studied species that have been wiped out of the area, like the Grizzly, Gray Wolf and Bison, as well as species that have moved in, like Moose. The exceptionally high altitudes define unique ecosystems of global importance.

The Crown of the Continent Biosphere in Montana includes Glacier National Park (see photo of author & son above). (Perhaps to de-emphasize the shrinking glacier problem, the Biosphere dropped the name “Glacier” in 2017). The biosphere is home to rare charismatic species like Grizzly Bears, Lynx and Wolverines. Over 100 years of scientific data on wildfires, snowpack, species populations, and more have been collected and shared from this park and its sister park Waterton Glacier in Canada. Like Rocky Mountain, the biospheres here cover the Continental Divide, which defines the direction of rivers across the US to the Atlantic & Pacific, but from here rivers also flow north to the Arctic, making these biospheres of particularly important for studying migrating species.

Yellowstone-Grand Teton Biosphere in Wyoming obviously includes Yellowstone and Grand Teton National Parks. One of the most intact predator-prey-scavenger biospheres on earth, with large herds of Elk and Bison, Grizzly Bears, Cutthroat Trout and Bald Eagles, and unrestricted rivers, this is an exceptionally important global biosphere.

Unfortunately, in 2017 the Trump Administration canceled 5 other biospheres in the Rocky Mountain Region. Apparently, the Israelis were upset that Palestinians were allowed to participate in UNESCO and used the place name “Palestine” in the name of a joint heritage site, so the US ended over forty years of scientific cooperation and research sharing with the world and removed many US biospheres from the global program.

The programs canceled in 2017 included three in Colorado: Central Plains Biosphere in the northeast, Fraser Biosphere in central, and Niwot Ridge Biosphere in the north. The Central Plains was particularly valuable in the study of short grass prairie ecosystems. Fraser was important in studying the interaction of forests, rivers and climate. Niwot Ridge contributed important research into alpine tundra ecosystems, glaciers, high altitude plants and climate change.

In Montana, the Coram Biosphere, west of Glacier NP ended in 2017. Coram was important in the study of forest regeneration and forest management. And in Utah, the Desert Biosphere, near Great Basin also ended in 2017. Desert, begun by President Hoover, contributed to our understanding of scrublands and pasturelands in hot and dry areas.

I’ve traveled in, through or next to all five canceled Rocky Mountain biospheres in my electric car, and they’re also uniquely beautiful places. But biospheres aren’t primarily meant for tourists, they’re meant for nature and for scientists. While some research continues at many of these sites, the international scientific and policy management cooperation was cut off. Especially facing a global climate crisis, we need to be actively cooperating to find global solutions to our ecological threats. Also, it seems bizarre to remove our own natural scientific research areas from participation in international science, due to deep-rooted political feuds in the Mideast. I hope these irrational mistaken biosphere withdrawals can be reversed by the current or future administrations, so that the global learning can continue.

Biosphere 2

From 1991 to 1993, eight people lived in this huge sealed greenhouse or giant terrarium in Arizona, growing their own food and attempting to live without outside intervention. Built at a cost of some $250 million, the complex includes the artificial ocean above, multiple tropical growing zones, industrial HVAC, and even a unique, massive ‘lung’ to equalize air pressure at different temperatures. Results were mixed, but there are important lessons to be learned.

Humans like to believe we can control our environment and that we have conquered nature. The truth is that we don’t completely understand nature, and when we try to control it, there are unintended consequences.

The most serious problem was a gradual reduction in oxygen, which threatened to kill the participants by around day 500 and required emergency intervention. Despite all the plants, overall, the system produced too much carbon dioxide. Also, the participants complained of constant hunger, unable to eat enough calories per day, which made it difficult to complete their extensive daily chores. Many plants and pollinators did not survive, but stowaways like cockroaches thrived. Still, they survived for two full years. Others later managed shorter stints, but bickering and mismanagement soon ended fully sealed living experiments.

From 1995 to 2003, Columbia University managed the site and completed groundbreaking research here scientifically proving up to 90% declines in oceanic coral due to artificially high levels of atmospheric carbon dioxide. Unfortunately, the coral later died when the site went back on the market, although there are plans to try to reintroduce it. Today the site is run by Arizona State University, which offers both a general self-guided tour and specialized guided tours, in addition to hosting students and researchers. When fully funded, the semi-tropical desert forests are very well controlled and measured, enabling many scientific experiments on micro ecosystems to be carried out under laboratory conditions. Tracers can be added to water and carbon dioxide, so researchers can figure out exactly what plants are doing in different conditions. Unfortunately, the whole complex is extremely energy intensive, and it is run on diesel and natural gas, which both contribute carbon pollution to exacerbate the climate crisis.

Some believe that technology will allow us to adapt to the worst effects of climate change. The truth is that we need to spend our time, energy and money trying to protect Biosphere 1 (Earth) from carbon pollution. This massive, extremely expensive, carefully engineered and scientifically researched project could barely take care of eight people for two years. That’s neither an efficient nor effective use of resources, but it quickly illustrates how difficult it is to scale environmental technologies to the point that they are practical. How big of a terrarium would we need to feed eight billion people? Far better to take care of the Earth, while we still have hope.

Forest Wildfires

I know it’s winter, but we need to talk about wildfires. There is a common, simple-minded view—popular among those who deny climate change—that overzealous park employees unnaturally suppressed fires, causing wildfires today. End of story. Once we ‘catch up’ on the ‘fire deficit’ everything will be fine. This is bunk.

Last year Canada had a record-smashing year of wildfires, and the frequency of wildfires far exceeds what is normal, considering the naturally slow growth rate of trees in boreal forests. Most of these fires were in remote northern Canada, where historic fires were not even reported, let alone suppressed. The estimated number of fires was not too high, but many of the fires were mega fires, burning over seven times as many acres as the modern historic average. There is only one explanation for the scale of the wildfires last year, and it isn’t Smokey the Bear. The primary cause of increasingly severe forest fires is carbon pollution. 

The first humans to change natural fire ecology in North America were natives who for centuries used fires in the valley for agriculture and to attract game with new grass. The most destructive humans by far were loggers who clear cut whole forests. During the Great Depression, roads and campgrounds were developed in both old and regrown forests, bringing millions of visitors who parked their hot cars on dry grass, dropped their cigarettes on pine needles and left their campfires unattended, causing a dramatic increase in forest fires. Firefighters responded by putting out fires when they threatened nearby communities.

We changed forest fire ecology in complex ways over centuries, so the simple ‘fire suppression’ explanation is false. We don’t know exactly what the forest’s natural ecology was like before man started playing with fire here, but man’s brief experiments for a few decades last century—causing wildfires due to camping and suppressing some fires at the edges—all account for maybe 2% of the life of a Giant Sequoia. Yosemite park rangers tracked all fires within the park since the 1930’s, and for decades none of the fires were large enough to matter to the overall health of the forests until recently. Past fires were often 100 or maybe 1000 acres, but recent forest fires are 100,000 or 1,000,000 acres. Our hotter climate has changed everything. Now we need to change our perspective from our recent past to the consequences of our carbon pollution on the future. Extinction is not a mistake we can correct later. 

California has the most national parks with 28 park units, and about 12 of them have some type of large forest, often wilderness. I’ve been in all of those forest parks in the past year or so, and 9 now have huge swaths of dead trees from recent wildfires. 

Only Muir Woods, a small coastal redwood forest park along a creek surrounded by wealthy suburbs, has been spared. Pinnacles has had multiple wildfires in the past three years, but firefighters managed to contain them quickly. Even foggy Redwood park lost 11,000 acres in 2003 due to the Canoe Fire. 

This level of wildfire is not normal; it is out of control, and it is getting worse. Discussing past firefighting efforts and increasing the rate of manmade fires is not going to fix the problem. If we do not stop our carbon pollution, then 100 years of environmentalists’ efforts to save these forests for future generations will be wasted. 

Capitol Reef National Park

/ bigdiff / 6 Comments

The dome in the middle reminded folks of the US Capitol, but the geologic speciality of the park is the reef, or Waterpocket Fold, one of the longest continually exposed monoclines (like a wrinkle) in the world, almost 100 miles north to south. Cathedral Valley in the north and Muley Twist Canyon in the south are difficult to access without a high clearance 4×4, but the geologic layers can all be seen in the middle cross section near the Fruita orchard. The Hickman Bridge trail above is a good place to see the dome, but the scenic drive along the fold is exceptional. The unpaved side trip into Capitol Gorge is particularly striking, and there’s a hike from the parking lot up to see the eroded round water-pockets for which the fold is named.

This is my favorite park to learn about the geology of the west, from the high country mountains like Great Basin and Rocky at 12,000 feet, to the high plateaus like Cedar Breaks at 10,000 feet and Bryce at 8,000 feet, to standing up country with Natural Bridges at 6,000 feet, Arches at 5,000 feet, Zion at 4,000 feet and the many layered Grand Canyon spanning from 8,000 to 2,000 feet, and all the way down to the low desert of Death Valley more than 250 feet below sea level. At Capitol Reef, the ranger’s geology talk explained how the changing climate and continental shifts over hundreds of millions of years left repeated layers of deposits, lifted them up unevenly and eroded them into the wonderful scenery we see today. The same patterns repeat, not just one ancient inland sea or forest or swamp or grassland or desert, but many repeated environments were slathered over one another and pressed into rock.

Why are there weird discolored greenish mounds along the Green River? Those were from one of the swampy periods (Morrison) when oxygen was low, materials were soft and clay-like and they contain late Jurassic dinosaur fossils. Why are there similar colored layers at much different altitudes? They were from different swampy periods and contain different fossils. What causes the alternating pink and beige layers of hoodoos and other rock formations? The layers are made of the same kind of rock, but in some years the iron oxidized and in others it couldn’t due to water changes. Where did all the sand come from to make all the sandstone layers? Much of the sand eroded from the old Appalachian Mountains, flowed down ancient rivers and blew across to the west.

Even if you’re completely uninterested in Geology, you might be interested in the outlaws who hid in the remote areas nearby, like the Wild Bunch, which included Butch Cassidy & the Sundance Kid. Or maybe tour the old orchard and learn about pioneers. Or take a moment to think of those Uranium miners, many Native Americans, who still suffer radiation poisoning, or think about the wildlife who can’t read the warning signs. This is an uncrowded and under appreciated national park. Highly recommended.
