The cactus thrives in the desert while the fern thrives in the wetland.
The fool will try to plant them in the same flowerbox.
The florist will sigh and add a wall divider and proper soil to both sides.
The grandparent will move the flowerbox halfway out of the sun.
The child will turn it around properly so that the fern is in the shade, and not the cactus.

Thoreau the “Patron Saint of Swamps” because he enjoyed being in them and writing about them said, “my temple is the swamp… When I would recreate myself, I seek the darkest wood, the thickest and most impenetrable and to the citizen, most dismal, swamp. I enter a swamp as a sacred place, a sanctum sanctorum… I seemed to have reached a new world, so wild a place…far away from human society. What’s the need of visiting far-off mountains and bogs, if a half-hour’s walk will carry me into such wildness and novelty.

Wetlands are actually unsung heroes. They nurture young fish, provide refuge to birds, bats, bugs, and sometimes to big mammals like panthers and bears. Mangroves, for instance, are trees and shrubs that inhabit coastal swamps, and they form peat that is home to clams, snails, crabs, and shrimp, and filter pollution out of the water. Their “interlaced roots protect tiny fish from ravenous jaws of larger fish, and even manatees and dolphins take refuge there.

As technological civilization diminishes the biotic diversity of the earth, language itself is diminished. As there are fewer and fewer songbirds in the air, due to the destruction of their forests and wetlands, human speech loses more and more of its evocative power. For when we no longer hear the voices of warbler and wren, our own speaking can no longer be nourished by their cadences. As the splashing speech of the rivers is silenced by more and more dams, as we drive more and more of the land’s wild voices into the oblivion of extinction, our own languages become increasingly impoverished and weightless, progressively emptied of their earthly resonance.17

Today an estimated 13 percent of birds are threatened, according to the International Union for Conservation of Nature. So are 25 percent of mammals and 41 percent of amphibians, in large part because of human activity. Hydropower and road construction imperil China’s giant pandas. The northern bald ibis, once abundant in the Middle East, has been driven almost to extinction by hunting, habitat loss, and the difficulties of doing conservation work in war-torn Syria. Hunting and the destruction of wetlands for agriculture drove the population of North America’s tallest bird, the whooping crane, into the teens before stringent protections along the birds’ migratory route and wintering grounds helped the wild flock build back to a few hundred. Little brown bats are dying off in the United States and Canada from a fungus that might have been imported from Europe by travelers. Of some 300 species of freshwater mussels in North America, fully 70 percent are extinct, imperiled, or vulnerable, thanks to the impacts of water pollution from logging, dams, farm runoff, and shoreline development.

The Measure of America, a report of the Social Science Research Council, ranks every state in the United States on its “human development.” Each rank is based on life expectancy, school enrollment, educational degree attainment, and median personal earnings. Out of the 50 states, Louisiana ranked 49th and in overall health ranked last. According to the 2015 National Report Card, Louisiana ranked 48th out of 50 in eighth-grade reading and 49th out of 50 in eighth-grade math. Only eight out of ten Louisianans have graduated from high school, and only 7 percent have graduate or professional degrees. According to the Kids Count Data Book, compiled by the Annie E. Casey Foundation, Louisiana ranked 49th out of 50 states for child well-being. And the problem transcends race; an average black in Maryland lives four years longer, earns twice as much, and is twice as likely to have a college degree as a black in Louisiana. And whites in Louisiana are worse off than whites in Maryland or anywhere else outside Mississippi. Louisiana has suffered many environmental problems too: there are nearly 400 miles of low, flat, subsiding coastline, and the state loses a football field–size patch of wetland every hour. It is threatened by rising sea levels and severe hurricanes, which the world’s top scientists connect to climate change.

If you allow a creek to go back to being a creek, if you let the trees and the bramble get overgrown, and you let the stream overrun its banks whenever it wants to, the wetland will take care of itself. The water that trickles into the ocean will be clean and pristine if everything is just left alone to work the way it was designed to work.

In recent years scientists have discovered that coastal wetlands—salt marshes, but also mangroves and saw grass meadows—store a quarter of the carbon found in the earth’s soil, despite covering only 5 percent of the planet’s land area. That means that an acre of healthy coastal wetlands will clean far more air than an acre of the Amazon. “They sequester about fifteen times more carbon than upland forests,” Beverly tells me. “But how effective are these ecosystems when they have been dammed, diked, culverted, or drained?

As long as the wetland looks pretty and also attracts ducks from time to time, it is regarded as a complete success. An attractive appearance is fine and is of considerable concern in urban developments.
It is the pretense that such wetlands also create rich habitats which is objectionable, when urban development is the primary cause of loss of diversity in a wide range of ecosystems around cities including wetlands.
The one ecologically positive thing that most created wetlands do a reasonable job of is water treatment, because the limited range of plants likely to survive the semi-toxic soils and waters of newly created wetlands are invariably colonisers that will also use up a wide range of nutrients.

couldn’t they join a good fight? The coastal land of Louisiana had long been slowly sinking into the Gulf of Mexico. The state’s coast provides 40 percent of the nation’s wetlands, and its commercial fisheries provide a quarter to a third of the nation’s seafood. Experts agree that a major cause of the land’s subsidence is the extraction of oil and saltwater intrusion. Over the years, oil companies have dredged hundreds of canals and laid down pipeline through which oil drilled in the Gulf has been piped inland. Saltwater seeps in along the canals, killing grasses that once provided protection against Louisiana’s frequent tropical storms. Since 1930, the state had already lost an area equal to the size of Delaware—an average football field every hour.

In the deep woods of the far North, under feathery leaves of fern, was a great fairyland of merry elves, sometimes called forest brownies.
These elves lived joyfully. They had everything at hand and did not need to worry much about living. Berries and nuts grew plentiful in the forest. Rivers and springs provided the elves with crystal water. Flowers prepared them drink from their flavorful juices, which the munchkins loved greatly.
At midnight the elves climbed into flower cups and drank drops of their sweet water with much delight. Every elf would tell a wonderful fairy tale to the flower to thank it for the treat.
Despite this abundance, the pixies did not sit back and do nothing. They tinkered with their tasks all day long. They cleaned their houses. They swung on tree branches and swam in forested streams. Together with the early birds, they welcomed the sunrise, listened to the thunder growling, the whispering of leaves and blades of grass, and the conversations of the animals.
The birds told them about warm countries, sunbeams whispered of distant seas, and the moon spoke of treasures hidden deeply in the earth.
In winter, the elves lived in abandoned nests and hollows. Every sunny day they came out of their burrows and made the forest ring with their happy shouts, throwing tiny snowballs in all directions and building snowmen as small as the pinky finger of a little girl. The munchkins thought they were giants five times as large as them.
With the first breath of spring, the elves left their winter residences and moved to the cups of the snowdrop flowers. Looking around, they watched the snow as it turned black and melted. They kept an eye on the blossoming of hazel trees while the leaves were still sleeping in their warm buds. They observed squirrels moving their last winter supplies from storage back to their homes. Gnomes welcomed the birds coming back to their old nests, where the elves lived during winters. Little by little, the forest once more grew green.
One moonlight night, elves were sitting at an old willow tree and listening to mermaids singing about their underwater kingdom.
“Brothers! Where is Murzilka? He has not been around for a long time!” said one of the elves, Father Beardie, who had a long white beard. He was older than others and well respected in his striped stocking cap.
“I’m here,” a snotty voice arose, and Murzilka himself, nicknamed Feather Head, jumped from the top of the tree. All the brothers loved Murzilka, but thought he was lazy, as he actually was. Also, he loved to dress in a tailcoat, tall black hat, boots with narrow toes, a cane and a single eyeglass, being very proud of that look.
“Do you know where I’m coming from? The very Arctic Ocean!” roared he.
Usually, his words were hard to believe. That time, though, his announcement sounded so marvelous that all elves around him were agape with wonder.
“You were there, really? Were you? How did you get there?” asked the sprites.
“As easy as ABC! I came by the fox one day and caught her packing her things to visit her cousin, a silver fox who lives by the Arctic Ocean.
“Take me with you,” I said to the fox.
“Oh, no, you’ll freeze there! You know, it’s cold there!” she said.
“Come on.” I said. “What are you talking about? What cold? Summer is here.”
“Here we have summer, but there they have winter,” she answered.
“No,” I thought. “She must be lying because she does not want to give me a ride.”
Without telling her a word, I jumped upon her back and hid in her bushy fur, so even Father Frost could not find me.
Like it or not, she had to take me with her.
We ran for a long time. Another forest followed our woods, and then a boundless plain opened, a swamp covered with lichen and moss. Despite the intense heat, it had not entirely thawed.
“This is tundra,” said my fellow traveler.
“Tundra? What is tundra?” asked I.
“Tundra is a huge, forever frozen wetland covering the entire coast of the Arctic Ocean.

Deep underground, microbes turn half a century's worth of city waste into methane. The gases and leachate are extracted through an extensive network of subterranean pipes and then used to power 22,000 nearby homes. While 150 million tons of garbage gradually decomposes unseen below the surface, above ground, the former dump reverts to meadows, woodland and saltwater marshes, providing a haven for wildlife and a massive park for the people of New York.
This is Fresh Kills in the 2020s. In 2001, the infamous landfill received its last, and saddest, consignments - the charred debris of the World Trade Center. Since then, it has been transformed into a 2,315-acre public park. Three times bigger than Central Park, it is the largest new green public space created within New York City for over a century, a mixture of wildlife habitats, bike trails, sports fields, art exhibits and playgrounds. This is poisoned land: fifty years' worth of landfill has killed for ever one of the city's most productive wetland ecosystems. Restoration is impossible. Instead, a brand new ecosystem is emerging on top of the toxic garbage

That story, of course, isn’t unique to California, or to beavers. Europeans began despoiling North American ecosystems the moment they set boots on the stony shore of the New World. You’re probably familiar with most of the colonists’ original environmental sins: They wielded an ax against every tree, lowered a net to catch every fish, turned livestock onto every pasture, churned the prairie to dust. In California’s Sierra Nevada, nineteenth-century gold miners displaced so much sediment that the sludge could have filled the Panama Canal eight times.14 We are not accustomed to discussing the fur trade in the same breath as those earth-changing industries, but perhaps we should. The disappearance of beavers dried up wetlands and meadows, hastened erosion, altered the course of countless streams, and imperiled water-loving fish, fowl, and amphibians—an aquatic Dust Bowl. Centuries before the Glen Canyon Dam plugged up the Colorado and the Cuyahoga burst into flame, fur trappers were razing stream ecosystems. “[Beavers’] systematic and widespread removal,” wrote Sharon Brown and Suzanne Fouty in 2011, “represents the first large-scale Euro-American alteration of watersheds.

Beyond a fence, they came to the swimming pool, which spilled over into a series of waterfalls and smaller rocky pools. The area was planted with huge ferns. “Isn’t this extraordinary?” Ed Regis said. “Especially on a misty day, these plants really contribute to the prehistoric atmosphere. These are authentic Jurassic ferns, of course.” Ellie paused to look more closely at the ferns. Yes, it was just as he said: Serenna veriformans, a plant found abundantly in fossils more than two hundred million years old, now common only in the wetlands of Brazil and Colombia. But whoever had decided to place this particular fern at poolside obviously didn’t know that the spores of veriformans contained a deadly beta-carboline alkaloid. Even touching the attractive green fronds could make you sick, and if a child were to take a mouthful, he would almost certainly die—the toxin was fifty times more poisonous than oleander. People were so naïve about plants, Ellie thought. They just chose plants for appearance, as they would choose a picture for the wall. It never occurred to them that plants were actually living things, busily performing all the living functions of respiration, ingestion, excretion, reproduction—and defense. But Ellie knew that, in the earth’s history, plants had evolved as competitively as animals, and in some ways more fiercely. The poison in Serenna veriformans was a minor example of the elaborate chemical arsenal of weapons that plants had evolved. There were terpenes, which plants spread to poison the soil around them and inhibit competitors; alkaloids, which made them unpalatable to insects and predators (and children); and pheromones, used for communication. When a Douglas fir tree was attacked by beetles, it produced an anti-feedant chemical—and so did other Douglas firs in distant parts of the forest. It happened in response to a warning alleochemical secreted by the trees that were under attack. People who imagined that life on earth consisted of animals moving against a green background seriously misunderstood what they were seeing. That green background was busily alive. Plants grew, moved, twisted, and turned, fighting for the sun; and they interacted continuously with animals—discouraging some with bark and thorns; poisoning others; and feeding still others to advance their own reproduction, to spread their pollen and seeds. It was a complex, dynamic process which she never ceased to find fascinating. And which she knew most people simply didn’t understand. But if planting deadly ferns at poolside was any indication, then it was clear that the designers of Jurassic Park had not been as careful as they should have been.

Ten years after they'd moved to Miami they'd left Stanley and Felice with family friends and Avis and Brian drove to Key West on a sort of second honeymoon. She remembers how the land dropped back into distance: wetlands, marsh, lazy-legged egrets flapping over the highway, tangled, sulfurous mangroves. And water. Steel-blue plains, celadon translucence.
She and Brian had rented a vacation cottage in Old Town, ate small meals of fruit, cheese, olives, and crackers, swam in the warm, folding water. Each day stirring into the next, talking about nothing more complicated than the weather, spotting a shark off the pier, a mysterious constellation lowering in the west. Brian sheltered under a celery-green umbrella while Avis swam: the water formed pearls on the film of her sunscreen. They watched the night's rise, an immense black curtain from the ocean.

The world ocean and all waterways, including lakes, rivers, and wetlands (collectively, blue space), cover over 71% of our planet. Keeping them healthy, clean, accessible, and biodiverse is critical to human health and well-being.
In addition to fostering more widely documented ecological, economic, and cultural diversities, our mental well-being, emotional diversity, and resiliency also rely on the global ecological integrity of our waters.
Blue space gives us half of our oxygen, provides billions of people with jobs and food, holds the majority of Earth's biodiversity including species and ecosystems, drives climate and weather, regulates temperature, and is the sole source of hydration and hygiene for humanity throughout history.
Neuroscientists and psychologists add that the ocean and wild waterways are a wellspring of happiness and relaxation, sociality and romance, peace and freedom, play and creativity, learning and memory, innovation and insight, elation and nostalgia, confidence and solitude, wonder and awe, empathy and compassion, reverence and beauty — and help manage trauma, anxiety, sleep, autism, addiction, fitness, attention/focus, stress, grief, PTSD, build personal resilience, and much more.
Chronic stress and anxiety cause or intensify a range of physical and mental afflictions, including depression, ulcers, colitis, heart disease, and more. Being on, in, and near water can be among the most cost-effective ways of reducing stress and anxiety.
We encourage healthcare professionals and advocates for the ocean, seas, lakes, and rivers to go deeper and incorporate the latest findings, research, and insights into their treatment plans, communications, reports, mission statements, strategies, grant proposals, media, exhibits, keynotes, and educational programs and to consider the following simple talking points:
•Water is the essence of life: The ocean, healthy rivers, lakes, and wetlands are good for our minds and bodies.
•Research shows that nature is therapeutic, promotes general health and well-being, and blue space in both urban and rural settings further enhances and broadens cognitive, emotional, psychological, social, physical, and spiritual benefits.
•All people should have safe access to salubrious, wild, biodiverse waters for well-being, healing, and therapy.
•Aquatic biodiversity has been directly correlated with the therapeutic potency of blue space. Immersive human interactions with healthy aquatic ecosystems can benefit both.
•Wild waters can serve as medicine for caregivers, patient families, and all who are part of patients’ circles of support.
•Realization of the full range and potential magnitude of ecological, economic, physical, intrinsic, and emotional values of wild places requires us to understand, appreciate, maintain, and improve the integrity and purity of one of our most vital of medicines — water.

The chorus of criticism culminated in a May 27 White House press conference that had me fielding tough questions on the oil spill for about an hour. I methodically listed everything we'd done since the Deepwater had exploded, and I described the technical intricacies of the various strategies being employed to cap the well. I acknowledged problems with MMS, as well as my own excessive confidence in the ability of companies like BP to safeguard against risk. I announced the formation of a national commission to review the disaster and figure out how such accidents could be prevented in the future, and I reemphasized the need for a long-term response that would make America less reliant on dirty fossil fuels.
Reading the transcript now, a decade later, I'm struck by how calm and cogent I sound. Maybe I'm surprised because the transcript doesn't register what I remember feeling at the time or come close to capturing what I really wanted to say before the assembled White House press corps:
That MMS wasn't fully equipped to do its job, in large part because for the past thirty years a big chunk of American voters had bought into the Republican idea that government was the problem and that business always knew better, and had elected leaders who made it their mission to gut environmental regulations, starve agency budgets, denigrate civil servants, and allow industrial polluters do whatever the hell they wanted to do.
That the government didn't have better technology than BP did to quickly plug the hole because it would be expensive to have such technology on hand, and we Americans didn't like paying higher taxes - especially when it was to prepare for problems that hadn't happened yet.
That it was hard to take seriously any criticism from a character like Bobby Jindal, who'd done Big Oil's bidding throughout his career and would go on to support an oil industry lawsuit trying to get a federal court to lift our temporary drilling moratorium; and that if he and other Gulf-elected officials were truly concerned about the well-being of their constituents, they'd be urging their party to stop denying the effects of climate change, since it was precisely the people of the Gulf who were the most likely to lose homes or jobs as a result of rising global temperatures.
And that the only way to truly guarantee that we didn't have another catastrophic oil spill in the future was to stop drilling entirely; but that wasn't going to happen because at the end of the day we Americans loved our cheap gas and big cars more than we cared about the environment, except when a complete disaster was staring us in the face; and in the absence of such a disaster, the media rarely covered efforts to shift America off fossil fuels or pass climate legislation, since actually educating the public on long-term energy policy would be boring and bad for ratings; and the one thing I could be certain of was that for all the outrage being expressed at the moment about wetlands and sea turtles and pelicans, what the majority of us were really interested in was having the problem go away, for me to clean up yet one more mess decades in the making with some quick and easy fix, so that we could all go back to our carbon-spewing, energy-wasting ways without having to feel guilty about it.
I didn't say any of that. Instead I somberly took responsibility and said it was my job to "get this fixed." Afterward, I scolded my press team, suggesting that if they'd done better work telling the story of everything we were doing to clean up the spill, I wouldn't have had to tap-dance for an hour while getting the crap kicked out of me. My press folks looked wounded. Sitting alone in the Treaty Room later that night, I felt bad about what I had said, knowing I'd misdirected my anger and frustration.
It was those damned plumes of oil that I really wanted to curse out.

Only three years after American soldiers seized the Mexican province of California, the Swamp Land Act of 1850 passed Congress, granting new states the right to sell flood-prone land to individuals as long as the water could be drained from it. The legislation sparked the nationwide annihilation of wetlands from the Florida Everglades to the San Francisco tidelands. The Swamp Land Act was a classic form of the get-rich-quick scheme that defined the colonial project: steal indigenous lands, auction them off to the highest bidder, and then enforce property taxes, guaranteeing a long-term source of funds. It would transfer the promise of future financial security away from the country’s first inhabitants. In just two years’ time, nearly 790,000 acres of California’s wetlands were shifted into the hands of fewer than two hundred private owners, who, having paid the bargain rate of $ 1.25 per acre with no money down, proceeded to dam, dike, drain, and fill the largest estuary on the Pacific coast.

Today there are twenty-nine dams and locks on the upper Mississippi, and the lower Mississippi is lined with levees and floodwalls. Instead of preserving the low-lying land at the Mississippi’s mouth, these river controls have contributed to its destruction by impounding land-replenishing sediment behind man-made barriers upstream. Thanks in part to these interventions, the Isle de Jean Charles, and the wetlands surrounding it, started to disappear, not just temporarily beneath floodwaters, but for good.

59. Creature Comforts Are Only Temporary
It was one of the most painful lessons of my life.
It was during the first time I attempted SAS selection. I was totally lost in a vast boggy wetland, torrential rain was driving down, and I was utterly spent.
I was also way behind time, and I knew it.
When I finally made it to the penultimate checkpoint, the corporals kept me there doing endless press-ups in the wet marsh with my heavy pack still on my back. I knew this was costing me even more valuable time and energy.
I was feeling fainter and fainter; I knew things were bad.
I was soon off again, wading across a fast-flowing, waist-deep stream, before climbing up through knee-deep mud towards the next 2,000-foot (600-metre) mountain ridge-line. I just had to keep going. Ten miles. Twenty miles. ‘Nothing good comes from quitting,’ I told myself, over and over again. ‘If I keep going, I will pass.’
But I was getting more and more delirious with fatigue. I didn’t know why this was happening, and I couldn’t control it. Maybe I hadn’t eaten or drunk enough, or perhaps it was just that the months of this relentless pace were finally taking their toll and I was at my limit.
Every couple of paces, my knees would buckle. If I stumbled, I couldn’t stop myself from falling.
Eventually I saw the trucks in the distance below me, symbolizing the end point. Wisps of smoke from army Hexi stoves curled upwards from the woods. Soon I would be warm, soon I would have a cup of hot tea. It was all I wanted.
But when I reached the end checkpoint I was told I had been failed - I had been too slow. My world fell inwards. I was sent off to make camp in the woods and rest for the night. The remaining recruits would be heading out for the night march in a few hours.
The next morning I would be returned to camp with the others who hadn’t made the grade. I was totally dejected.
That night in those woods, warm and dry under my shelter, blisters attended to, dry socks on, and out of the wind and rain, I learnt an enduring lesson: warm and dry doesn’t mean fulfilled and happy.

Once the first plant did somehow make its way onto land however, it took only a few million years for all of the continents to turn green, first with wetlands, and then with forests. Three billion years of evolution have produced only one life form that can reverse this process and make our planet significantly less green. Urbanization is decolonizing the surfaces that plants painstakingly colonized 400 million years ago, turning them back into hard and barren lands.

One night around two a.m., I heard the piano suddenly start playing at high volume. Going downstairs from my office to shut it off, I saw Salar sitting at the keyboard in the half-light, ripping through a Chopin scherzo and filling the small space with his frenetic finger work. I stood and watched as he flawlessly hammered out notes, the sound crashing against the walls, the windows, the furniture, as if it needed to break free and soar across the moonlit wetlands just outside our door.

Urban areas are home to more than half the people on earth—a proportion that will rise in the years ahead—and they’re responsible for more than three-quarters of the world’s economy. As they expand, many of the world’s fast-growing cities end up building over floodplains, forests, and wetlands that could absorb rising waters during a storm or hold reservoirs of water during a drought.

The adjective “intact” is earned by encompassing at least 500 square kilometers—which is roughly 125,000 acres—free of roads, power lines, mines, cities, and industrial farms. That’s the size of about 60,000 soccer fields, 146 Central Parks, or a single square of land 14 miles on a side. “Landscapes” is added to the term because natural forests have vital treeless places, such as rivers, lakes, wetlands, and mountaintops mixed in. In 2008, the group helped map all such forests globally. Worldwide, there are currently around 2,000 intact forest landscapes, or IFLs, comprising nearly a quarter of all the planet’s wooded lands. They are heavily concentrated in the five megaforests.

The weight of the pond presses water deep into the ground, recharging aquifers for use by downstream farms and ranches. Sediment and pollutants filter out in the slackwaters, cleansing flows. Floods dissipate in the ponds; wildfires hiss out in wet meadows. Wetlands capture and store spring rain and snowmelt, releasing water in delayed pulses that sustain crops through the dry summer. A report released by a consulting firm in 2011 estimated that restoring beavers to a single river basin, Utah’s Escalante, would provide tens of millions of dollars in benefits each year.4 Although you can argue with the wisdom of slapping a dollar value on nature, there’s no denying that these are some seriously important critters.

The lexeme alb/alf-, “elf,” derives from the Proto-Indo-European root albh-, whose primary meaning is “white, clear” (cf. Latin albus). This root also underlies the name of the famous Central European river the Elbe and the Old Norse noun elfr, which means “river.” In Old High German, the swan is called alpiz and the alder, albari, a tree that prefers wetlands and areas near water. For now, we should keep in mind the essential element I hope to draw out of these texts: the family of creatures to which Alberîch belongs is closely connected to water in its two most ancient symbolic forms: life—associated with the animus—and death—nibel, nifl.

The Scheffe test is the most conservative, the Tukey test is best when many comparisons are made (when there are many groups), and the Bonferroni test is preferred when few comparisons are made. However, these post-hoc tests often support the same conclusions.3 To illustrate, let’s say the independent variable has three categories. Then, a post-hoc test will examine hypotheses for whether . In addition, these tests will also examine which categories have means that are not significantly different from each other, hence, providing homogeneous subsets. An example of this approach is given later in this chapter. Knowing such subsets can be useful when the independent variable has many categories (for example, classes of employees). Figure 13.1 ANOVA: Significant and Insignificant Differences Eta-squared (η2) is a measure of association for mixed nominal-interval variables and is appropriate for ANOVA. Its values range from zero to one, and it is interpreted as the percentage of variation explained. It is a directional measure, and computer programs produce two statistics, alternating specification of the dependent variable. Finally, ANOVA can be used for testing interval-ordinal relationships. We can ask whether the change in means follows a linear pattern that is either increasing or decreasing. For example, assume we want to know whether incomes increase according to the political orientation of respondents, when measured on a seven-point Likert scale that ranges from very liberal to very conservative. If a linear pattern of increase exists, then a linear relationship is said to exist between these variables. Most statistical software packages can test for a variety of progressive relationships. ANOVA Assumptions ANOVA assumptions are essentially the same as those of the t-test: (1) the dependent variable is continuous, and the independent variable is ordinal or nominal, (2) the groups have equal variances, (3) observations are independent, and (4) the variable is normally distributed in each of the groups. The assumptions are tested in a similar manner. Relative to the t-test, ANOVA requires a little more concern regarding the assumptions of normality and homogeneity. First, like the t-test, ANOVA is not robust for the presence of outliers, and analysts examine the presence of outliers for each group. Also, ANOVA appears to be less robust than the t-test for deviations from normality. Second, regarding groups having equal variances, our main concern with homogeneity is that there are no substantial differences in the amount of variance across the groups; the test of homogeneity is a strict test, testing for any departure from equal variances, and in practice, groups may have neither equal variances nor substantial differences in the amount of variances. In these instances, a visual finding of no substantial differences suffices. Other strategies for dealing with heterogeneity are variable transformations and the removal of outliers, which increase variance, especially in small groups. Such outliers are detected by examining boxplots for each group separately. Also, some statistical software packages (such as SPSS), now offer post-hoc tests when equal variances are not assumed.4 A Working Example The U.S. Environmental Protection Agency (EPA) measured the percentage of wetland loss in watersheds between 1982 and 1992, the most recent period for which data are available (government statistics are sometimes a little old).5 An analyst wants to know whether watersheds with large surrounding populations have

suffered greater wetland loss than watersheds with smaller surrounding populations. Most watersheds have suffered no or only very modest losses (less than 3 percent during the decade in question), and few watersheds have suffered more than a 4 percent loss. The distribution is thus heavily skewed toward watersheds with little wetland losses (that is, to the left) and is clearly not normally distributed.6 To increase normality, the variable is transformed by twice taking the square root, x.25. The transformed variable is then normally distributed: the Kolmogorov-Smirnov statistic is 0.82 (p = .51 > .05). The variable also appears visually normal for each of the population subgroups. There are four population groups, designed to ensure an adequate number of observations in each. Boxplot analysis of the transformed variable indicates four large and three small outliers (not shown). Examination suggests that these are plausible and representative values, which are therefore retained. Later, however, we will examine the effect of these seven observations on the robustness of statistical results. Descriptive analysis of the variables is shown in Table 13.1. Generally, large populations tend to have larger average wetland losses, but the standard deviations are large relative to (the difference between) these means, raising considerable question as to whether these differences are indeed statistically significant. Also, the untransformed variable shows that the mean wetland loss is less among watersheds with “Medium I” populations than in those with “Small” populations (1.77 versus 2.52). The transformed variable shows the opposite order (1.06 versus 0.97). Further investigation shows this to be the effect of the three small outliers and two large outliers on the calculation of the mean of the untransformed variable in the “Small” group. Variable transformation minimizes this effect. These outliers also increase the standard deviation of the “Small” group. Using ANOVA, we find that the transformed variable has unequal variances across the four groups (Levene’s statistic = 2.83, p = .41 < .05). Visual inspection, shown in Figure 13.2, indicates that differences are not substantial for observations within the group interquartile ranges, the areas indicated by the boxes. The differences seem mostly caused by observations located in the whiskers of the “Small” group, which include the five outliers mentioned earlier. (The other two outliers remain outliers and are shown.) For now, we conclude that no substantial differences in variances exist, but we later test the robustness of this conclusion with consideration of these observations (see Figure 13.2). Table 13.1 Variable Transformation We now proceed with the ANOVA analysis. First, Table 13.2 shows that the global F-test statistic is 2.91, p = .038 < .05. Thus, at least one pair of means is significantly different. (The term sum of squares is explained in note 1.) Getting Started Try ANOVA on some data of your choice. Second, which pairs are significantly different? We use the Bonferroni post-hoc test because relatively few comparisons are made (there are only four groups). The computer-generated results (not shown in Table 13.2) indicate that the only significant difference concerns the means of the “Small” and “Large” groups. This difference (1.26 - 0.97 = 0.29 [of transformed values]) is significant at the 5 percent level (p = .028). The Tukey and Scheffe tests lead to the same conclusion (respectively, p = .024 and .044). (It should be noted that post-hoc tests also exist for when equal variances are not assumed. In our example, these tests lead to the same result.7) This result is consistent with a visual reexamination of Figure 13.2, which shows that differences between group means are indeed small. The Tukey and
”

Scheffe tests also produce “homogeneous subsets,” that is, groups that have statistically identical means. Both the three largest and the three smallest populations have identical means. The Tukey levels of statistical significance are, respectively, .725 and .165 (both > .05). This is shown in Table 13.3. Figure 13.2 Group Boxplots Table 13.2 ANOVA Table Third, is the increase in means linear? This test is an option on many statistical software packages that produces an additional line of output in the ANOVA table, called the “linear term for unweighted sum of squares,” with the appropriate F-test. Here, that F-test statistic is 7.85, p = .006 < .01, and so we conclude that the apparent linear increase is indeed significant: wetland loss is linearly associated with the increased surrounding population of watersheds.8 Figure 13.2 does not clearly show this, but the enlarged Y-axis in Figure 13.3 does. Fourth, are our findings robust? One concern is that the statistical validity is affected by observations that statistically (although not substantively) are outliers. Removing the seven outliers identified earlier does not affect our conclusions. The resulting variable remains normally distributed, and there are no (new) outliers for any group. The resulting variable has equal variances across the groups (Levene’s test = 1.03, p = .38 > .05). The global F-test is 3.44 (p = .019 < .05), and the Bonferroni post-hoc test similarly finds that only the differences between the “Small” and “Large” group means are significant (p = .031). The increase remains linear (F = 6.74, p = .011 < .05). Thus, we conclude that the presence of observations with large values does not alter our conclusions. Table 13.3 Homogeneous Subsets Figure 13.3 Watershed Loss, by Population We also test the robustness of conclusions for different variable transformations. The extreme skewness of the untransformed variable allows for only a limited range of root transformations that produce normality. Within this range (power 0.222 through 0.275), the preceding conclusions are replicated fully. Natural log and base-10 log transformations also result in normality and replicate these results, except that the post-hoc tests fail to identify that the means of the “Large” and “Small” groups are significantly different. However, the global F-test is (marginally) significant (F = 2.80, p = .043 < .05), which suggests that this difference is too small to detect with this transformation. A single, independent-samples t-test for this difference is significant (t = 2.47, p = .017 < .05), suggesting that this problem may have been exacerbated by the limited number of observations. In sum, we find converging evidence for our conclusions. As this example also shows, when using statistics, analysts frequently must exercise judgment and justify their decisions.9 Finally, what is the practical significance of this analysis? The wetland loss among watersheds with large surrounding populations is [(3.21 – 2.52)/2.52 =] 27.4 percent greater than among those surrounded by small populations. It is up to managers and elected officials to determine whether a difference of this magnitude warrants intervention in watersheds with large surrounding populations.10

Beyond One-Way ANOVA The approach described in the preceding section is called one-way ANOVA. This scenario is easily generalized to accommodate more than one independent variable. These independent variables are either discrete (called factors) or continuous (called covariates). These approaches are called n-way ANOVA or ANCOVA (the “C” indicates the presence of covariates). Two way ANOVA, for example, allows for testing of the effect of two different independent variables on the dependent variable, as well as the interaction of these two independent variables. An interaction effect between two variables describes the way that variables “work together” to have an effect on the dependent variable. This is perhaps best illustrated by an example. Suppose that an analyst wants to know whether the number of health care information workshops attended, as well as a person’s education, are associated with healthy lifestyle behaviors. Although we can surely theorize how attending health care information workshops and a person’s education can each affect an individual’s healthy lifestyle behaviors, it is also easy to see that the level of education can affect a person’s propensity for attending health care information workshops, as well. Hence, an interaction effect could also exist between these two independent variables (factors). The effects of each independent variable on the dependent variable are called main effects (as distinct from interaction effects). To continue the earlier example, suppose that in addition to population, an analyst also wants to consider a measure of the watershed’s preexisting condition, such as the number of plant and animal species at risk in the watershed. Two-way ANOVA produces the results shown in Table 13.4, using the transformed variable mentioned earlier. The first row, labeled “model,” refers to the combined effects of all main and interaction effects in the model on the dependent variable. This is the global F-test. The “model” row shows that the two main effects and the single interaction effect, when considered together, are significantly associated with changes in the dependent variable (p < .000). However, the results also show a reduced significance level of “population” (now, p = .064), which seems related to the interaction effect (p = .076). Although neither effect is significant at conventional levels, the results do suggest that an interaction effect is present between population and watershed condition (of which the number of at-risk species is an indicator) on watershed wetland loss. Post-hoc tests are only provided separately for each of the independent variables (factors), and the results show the same homogeneous grouping for both of the independent variables. Table 13.4 Two-Way ANOVA Results As we noted earlier, ANOVA is a family of statistical techniques that allow for a broad range of rather complex experimental designs. Complete coverage of these techniques is well beyond the scope of this book, but in general, many of these techniques aim to discern the effect of variables in the presence of other (control) variables. ANOVA is but one approach for addressing control variables. A far more common approach in public policy, economics, political science, and public administration (as well as in many others fields) is multiple regression (see Chapter 15). Many analysts feel that ANOVA and regression are largely equivalent. Historically, the preference for ANOVA stems from its uses in medical and agricultural research, with applications in education and psychology. Finally, the ANOVA approach can be generalized to allow for testing on two or more dependent variables. This approach is called multiple analysis of variance, or MANOVA. Regression-based analysis can also be used for dealing with multiple dependent variables, as mentioned in Chapter 17.

For human beings to destroy the biological diversity of God's creation; for human beings to degrade the integrity of the earth by causing changes in its climate, by stripping the earth of its natural forests or destroying its wetlands; for human beings to contaminate the earth's waters, its land, its air, and its life -- these are sins.

had a visit from the EPA the day before Collins announced he was taking over. They wanted to inspect the farm for some wetland to see if there were any endangered animals that needed protecting. I told them we had nothing but dry land, but they threatened to return with a fly over. Haven’t heard a thing since.

The only thing longer were his fingers, which were tall and grasslike when his hands were up. Perhaps that’s why his palms were always a bit moist. They were the wetlands and his fingers the bulrushes that grew at the edges of them.

At the lab my professor suggested that, since it was such an amazing day, perhaps I could take the exam outside in the wetland wilderness reserve that surrounded the lab. The view of the swamp was stunning! Somehow it had never seemed beautiful to me before. She asked that I take my notebook and pencil out. “Please draw for me the complete development of the chick from fertilization to hatching. That is the only question.” I gasped, “But that is the entire course!” “Yes, I suppose it is, but make-up exams are supposed to be harder than the original, aren’t they?” I couldn’t imagine being able to regurgitate the entire course. As I sat there despondently, I closed my eyes and was flooded with grief. Then I noticed that my inner visual field was undulating like a blanket that was being shaken at one end. I began to see a movie of fertilization! When I opened my eyes a few minutes later, I realized that the movie could be run forward and back and was clear as a bell in my mind’s eye, even with my physical eyes open. Hesitantly, I drew the formation of the blastula, a hollow ball of cells that develops out of the zygote (fertilized egg). As I carefully drew frame after frame of my inner movie, it was her turn to gape! The tiny heart blossomed. The formation of the notochord, the neural groove, and the beginnings of the nervous system were flowing out of my enhanced imagery and onto the pages. A stupendous event—the animated wonder of embryonic growth and the differentiation of cells—continued at a rapid pace. I drew as quickly as I could. To my utter amazement, I was able to carefully and completely replicate the content of the entire course, drawing after drawing, like the frames of animation that I was seeing as a completed film! It took me about an hour and a quarter drawing as fast as I could to reproduce the twenty-one-day miracle of chick formation. Clearly impressed, my now suddenly lovely professor smiled and said, “Well, I suppose you deserve an A!” The sunlight twinkled on the water, the cattails waved in the gentle breeze, and the gentle wonder of life was everywhere.

Portland and Seattle and Vancouver, they were beautiful cities, with their own positive qualities . . . but what they weren’t was infinitely capable of expansion. There were protected wetlands and forests to every side, mountain microclimates and endangered species under the protection of the federal government. The Pacific Northwest was already full, sorry, and it wasn’t looking to double its population any time soon.

the former head of Yale’s School of Forestry writes in the introduction to his latest book, The Bridge at the Edge of the World: Half the world’s tropical and temperate forests are now gone. The rate of deforestation in the tropics continues at about an acre a second. About half the wetlands and a third of the mangroves are gone. An estimated ninety percent of the large predator fish are gone, and 75 percent of marine fisheries are now over-fished or fished to capacity. Twenty percent of the corals are gone and another twenty percent severely threatened. Species are disappearing at rates about a thousand times faster than normal. The planet has not seen such a spasm of extinction in sixty-five million years, since the dinosaurs disappeared.

For Charleston and Rossville residents, the forest around Clay Pit Ponds was an irreplaceable natural area with native and industrial history. In 1951, Parks Commissioner Robert Moses proposed filling in the freshwater wetlands with trash to prepare the land for development. The Federation of Sportsmen and Conservationists, the Staten Island Museum, and the Audubon Society teamed up to save the seven ponds in the preserve, home to herons, ducks, muskrats, and bitterns. “I can’t imagine any park commissioner in the world permitting the dumping of garbage into such beautiful ponds,” said W. Lynn McCracken, chairman of the Park Association of Staten Island.

Because ibis don’t eat silverside and pickles sandwiches,’ Dad says. ‘You’re only giving it the sandwich chunks because you want to feel good about yourself. That’s a selfish mindset. You start feeding that bird from this window every day then it’ll start dropping by every afternoon like we’re fuckin’ Big Rooster and it brings its friends and then none of those birds get the strength and exercise they usually get from finding food the hard way so you drastically alter their metabolisms, not to mention cause widespread civil war among the Bracken Ridge ibis community as they battle to be the first to chomp into your silverside and pickles treat. Moreover, you suddenly get an unnaturally high level of birds in one place, which affects the ecological balance of the whole Bracken Ridge area. I know I don’t always practise this but, basically, you know, the whole point of life is doing things that are right over things that are easy. Because you want to feel good about yourself, suddenly the ibis are spending less time in the wetlands on a tree and more time on the ground in a fuckin’ car park rubbing shoulders with the pigeons, and then we start getting inter-species contact and weaker immune systems in the birds and higher stress hormones and from that little petri dish of dynamite springs salmonella

By felling poplars and willows to build dams, beavers single-handedly transform temperate forests into wetlands, which then attract and support a remarkable array of neighbors: pileated woodpeckers drilling nesting cavities into dead trees; wood ducks and Canada geese settling in abandoned beaver lodges; herons and kingfishers and swallows enjoying the benefits of the “artificial” pond, along with frogs, lizards, and other slow-water species like dragonflies, mussels, and aquatic beetles. As do those underwater colonies of coral, the beaver creates a platform that sustains an amazingly diverse assemblage of life.

Environmentalists like to say that defeats are permanent, victories temporary. Extinction, like death, is forever, but protection needs to be maintained. But now, in a world where restoration ecology is becoming increasingly important, it turns out that even defeats aren't always permanent. Across the United States and Europe, dams have been removed, wetlands and rivers restored, once-vanished native species reintroduced, endangered species regenerated.

And that the only way to truly guarantee that we didn’t have another catastrophic oil spill in the future was to stop drilling entirely; but that wasn’t going to happen because at the end of the day we Americans loved our cheap gas and big cars more than we cared about the environment, except when a complete disaster was staring us in the face; and in the absence of such a disaster, the media rarely covered efforts to shift America off fossil fuels or pass climate legislation, since actually educating the public on long-term energy policy would be boring and bad for ratings; and the one thing I could be certain of was that for all the outrage being expressed at the moment about wetlands and sea turtles and pelicans, what the majority of us were really interested in was having the problem go away, for me to clean up yet one more mess decades in the making with some quick and easy fix, so that we could all go back to our carbon-spewing, energy-wasting ways without having to feel guilty about it.

In the 1990 election campaign both Labour and National parties adopted ambitious targets to reduce greenhouse gas emissions. The country at that point was near carbon-neutral, with sources of emissions balanced by forestry which s3equestered the carbon. However, in the coming decade emissions would skyrocket as New Zealanders drove more; trucks replaced rail and shipping for freight; coal and gas were increasingly burnt for electricity; vast swathes of the country’s farms and wetlands were converted to dairy farming; and coal was used to convert that milk to powder for export. The National government spent the 1990s anguishing over what tool to use to reduce emissions and ended up doing nothing. Labour came in in 1999, signed up to the Kyoto Protocol and announced a carbon tax, but set it so far in the future that coalition politics eventually killed it. Meanwhile, every year, NZ’s net emissions increased from cars, cows and coal. Labour took climate pollution out of the RMA, relying on voluntary commitments and technological wishes… By 2008 NZ’s emissions were 25% higher than they had been in 1990.
