A Brief History of the American Wetland Forests

2022-08-23T08:00:33+00:00

In 1764, 25 years before he would become the first President of the United States, George Washington and five partners formed a company called Adventurers for Draining the Dismal Swamp. A surveyor by trade, Washington had thoroughly explored the perimeter of a million-acre wetland forest on what is now land bordering the states of Virginia and North Carolina. He called this area the Great Dismal Swamp and described it as a “glorious paradise” full of creatures to be hunted. A paradise rich with natural resources. Still, the Adventurers for Draining the Dismal Swamp, empowered by the General Assembly of Virginia, who granted them financing and permission to cut canals through even private lands, undertook a massive venture to clear cut vast stretches, selling the lumber and the promise of soon-to-be dry, arable land.

George Washington and his company were, of course, not the only ones harvesting the lumber from American wetlands. In the last 300 years, the majority of wetlands in the contiguous United States have been lost to logging or converted to land for agriculture or urban development. When European colonizers first arrived in the 1600s, the land was covered in approximately 221 million acres of wetlands - by the 1980s, only 103 million acres remained. Twenty-two states have lost 50% or more of their wetland forests and six states have lost more than 85%.

Through the 1700s especially, wetlands and swamps in particular were considered blights on what could be prosperous land. They “bred disease”, restricted travel, and took up rich soil where crops could be instead - far from favorable for frontier folk. The choice to clear the wetlands seemed natural, because these new settlers were oblivious to the resources that prospered in them and the protection they provided.

In the mid-1800s, the US government passed the Swamp Land Acts of 1849, 1850, and 1860 – each turning federal land containing swamps over to states that promised to drain them. During this time, the US was going through a period of rapid expansion. The population was growing quickly, both through domestic childbirth and immigration. While the country was also expanding westward, the need for farmable land nearby was high. So, again, the choice to clear more wetlands seemed natural.

Over the centuries, the American wetlands - refashioned to suit its new settlers - have changed drastically. While clearing the wetlands made sense at the time, we’ve come to learn that wetlands are invaluable resources and the long-term effects of this habitat loss has become clear.

Wetlands are an essential part of regional ecosystems – in which we’re included. We need wetlands to sustain our water supply, both because they work to filter pollutants and because they’re a source of water. They also work to protect our communities from severe weather, like hurricanes and flooding, by dampening the force with which they hit the land and by preventing land corrosion. Additionally, wetlands sequester approximately 20-30% of global carbon emissions - peatlands on their own store twice as much carbon as the world’s forests despite covering only 3% of the planet’s surface. These areas are also home to unique wildlife and fascinating plants; one-third of the currently-listed endangered species rely on wetlands to survive.

As the second driest state in the country, it’s no surprise that wetlands account for only 1% of Utah’s total land coverage. Because they’re so rare within our state, that makes them even more valuable. In an arid landscape, we need all the water we can get and our wetlands provide a hefty portion of our water supply. They’re also essential tools in preventing flooding, the costliest and most prevalent hazard in Utah. Although Utah’s wetlands are still in danger, we thankfully have many individuals in our community working to preserve and restore these valuable features of our state. Nonprofit communities (like the Sageland Collaborative and TreeUtah) along with governmental organizations (like the Utah Geological Survey) and numerous individuals throughout the state are working hard to maintain our wetlands.

Creating Tiny Forests Using the Miyawaki Method

2022-08-16T09:15:00+00:00

The World Needs Forests

Forests are important. They are home to 80% of the globe’s wildlife population, they reduce soil erosion, lessen the impact of floods, and they remove incredible amounts of carbon-dioxide from our atmosphere, ensuring we have breathable air. The tropical forests alone store around 250 billion tons of carbon. Without forests cleaning our air, life on Earth couldn’t continue – at least not for us – but we continue to lose our forests at a concerning rate. Between 1990 and 2015, we lost 129 million hectares of forest (nearly 500,000 square miles). While deforestation has slowed, we are far from reaching a balanced, sustainable relationship with our forests. Our forests – and us in turn – will only survive if we deploy all available means to reduce deforestation and support new growth.

Afforestation – planting forests upon land previously unforested – can be a massive undertaking, but it’s one of the few things communities can do to soften the blow of global deforestation. Thanks to the late Akira Miyawaki, Japanese botanist and specialist in natural vegetation restoration, a method for afforestation has been developed that allows for small-scale, rapid forestation. This method is now commonly known as the Miyawaki Method.

The Miyawaki Method

The Miyawaki Method was developed to support the rapid growth of diverse native plant species in relatively small spaces with minimal maintenance. The method only requires a minimum space of 1000 square feet, grows ten times faster than naturally-growing forests, and the planted forest can survive nearly maintenance-free after only three years of growth. The rapid growth of Miyawaki forests is attributed to the densely-packed planting and the use of native plant species. Native species are, of course, going to be the best candidates to thrive in the selected planting location, because they’ve evolved over the course of centuries to do just that. A biodiverse selection of plants also lends itself to the long-term stability of the forest – diversity creates a layered canopy and ecological resilience. Then, being packed closely together, they’re forced into a highly competitive race to soak up the sunlight, resulting in rapid growth. After 20-30 years, the surviving plants and trees will reach heights that would have taken 150-200 years to reach in a natural process.

The resulting tiny forest is also densely-packed with benefits. In addition to supporting local biodiversity and the benefits that always come with new trees, Miyawaki forests are also 30 times better at dust and noise reduction and absorb up to 30 times more carbon-dioxide than monoculture planting projects.

Because the Miyawaki method can be applied in areas with limited land and resources while still resulting in a flourishing forest, it’s perfect for urban settings. A small parcel of land, whether it’s an empty lot or a small portion of a public park, can easily be turned into an urban forest. Urban forests are essential in mitigating the effects of climate change – both locally and globally. Our efforts on the local-scale to rehabilitate and create new forests is an important contribution to the global concerted effort to ensure a livable planet for future generations. With critical deadlines for meaningful climate action approaching quickly, we need to act quickly. Thanks to Akira Miyawaki, we have one more tool at our disposal to make swift, meaningful change.

Forget the Grass, Trees Need Your Help

2022-08-02T09:15:00+00:00

A perfectly green lawn, a long-time indicator of a functioning household and a long-time indicator of wasted resources. The Western fascination with grass lawns goes way back, originating in the gardens of the 18th century English and French upper-class. Drawing inspiration from launds – grassy clearings among trees - in the surrounding European forests, the wealthy sought to recreate the experience in their expansive gardens, leading to what we now recognize as lawns. Lawns eventually made their way to the Americas in the 19th century through our own historical elites – like Thomas Jefferson, an avid horticulturalist. Although home gardens in the US remained dedicated to consumable vegetation for several decades, by the mid-19th century, focus shifted to the ornamental. After the Centennial Exhibition in Philadelphia in 1876, where the USDA presented a how-to exhibit on growing your own grass lawn, interest steadily grew throughout the next 100 years. After several innovations made in lawncare in the early 1900s, grass lawns became a standard in the booming American suburbs. Now, another 100 years later, lawns are still as commonplace as ever, but do we have the means to keep this tradition alive?

In short, yes, we do. Despite the megadrought and surging heatwaves, our lawns can survive, because they’re well-propagated for hardship. Of all the plants in our garden, grass is sure to be the one that needs the least amount of water to survive. Although it might brown, it’s still alive and the green will return next year. This browning is part of grass’s seasonal cycle. Like other perennials, grass enters a period of dormancy once it undergoes the stresses of their disfavored seasons. This stage in its annual cycle can be delayed with extensive watering, but our limited resources would be best spent on plants in the garden that need it more.

Trees need our help most. Arguably the most valuable plants in our gardens because of the benefits they provide for our homes and communities, trees should be our top watering priority. While grasses only need half an inch (~1 quart) of water every 2-4 weeks to survive the season, trees require 5-50 gallons of water a week (or more, if the tree is especially large). As sturdy as they appear to be, trees are far more delicate than grass and they need our help to survive the ongoing megadrought, which is predicted to end in 2030 at the earliest. Paired with the fact that extended drought events are expected to become more severe and more common, our focus-shift away from grass and towards trees will likely and necessarily be permanent.

Salt Lake City’s canopy has been steadily receding since the early 2000s, largely due to trees being neglected within recurring periods of drought. Without adequate water, trees either die off or they become too brittle to withstand high winds and dense snow fall, leading to broken branches or treefall. In addition to causing damage to anything beneath them when this happens, we lose the irreplaceable benefits old-growth trees provide. Benefits like cleaner air and shade – things we’ll be immeasurably thankful for in the harsh Summers ahead, things grass can’t provide. Grass doesn’t do much for us and it doesn’t need our help, so let’s concentrate on the plants that do, trees.

No Shade, No Gains

2022-03-30T14:45:14+00:00

There is a Chinese proverb that says, “the best time to plant a tree is twenty years ago. The second best time is now”.

Trees are complex beautiful things that provide us benefits we may take for granted without realizing it. They are mighty carbon warriors who take in excess carbon out of the atmosphere and in turn oxygenate our earth. Trees are also great creators of shade, our protectors against the sun’s rays when it gets too much. Shade from tree canopy, however, is not distributed equitably here in Salt Lake City and the effects are substantially felt on the west side. At TreeUtah we are working to plant more trees each year through our West Side Initiative. All people have a right to nature and we are initiating change by planting trees.

The inaccessibility of tree canopy coverage in an urban environment inevitably leads to consequences from the heat island effect. The heat island effect is not new, but as we increasingly urbanize now and in years down the line, areas will experience higher overall temperatures (up to 25 degrees Fahrenheit more during the hottest afternoons) if greenspace is not prioritized and dark surfaces like asphalt and buildings become more dominant.

Adding trees into spaces, however, will mitigate a common concern in urban areas which is ground-level ozone. Ground-level ozone is a harmful pollutant made from the interaction of the sun, volatile organic compounds found in common household products, and nitrogen oxide from car exhaust. Experiencing hotter days because of climate change and the urban heat island certainly does not help our ground-level ozone levels. With one of the benefits of trees being that they lower air pollution, trees are one solution to improve ground-level ozone and help individuals who are medically sensitive or who may be prone to suffer from illnesses correlated to bad air quality.

Adding things like trees in areas will also foster a sense of place and belonging for individuals because of bringing people together in outdoor spaces that seem more inviting. For further info on the social, environmental, and economic benefits provided to us each day by trees, check out our about page.

Not that long ago, the pandemic started to change the way we work. With workplace culture increasingly switching to remote, people are gravitating toward spending more time outside and participating in outdoor activities. However, we cannot reap the ultimate benefits from these experiences if basic things such as tree cover and green space are lacking. These benefits that trees provide us like improving air quality, helping the heat island, along with the change in our time spent in nature, all build up to why trees are so important in planting equitably on the streets and in places like Title I schools. Our West Side Initiative coincides with Mayor Mendenhall’s four year plan of planting an additional 1,000 trees just on the west side of Salt Lake City each year. Keep your eye out for our next community tree planting on the west side by keeping up to date on our events.

Why We Need Old Growth Forests

2022-09-29T09:30:00+00:00

In 1859, Lt. Edward Beale travelled through the forests of northern Arizona and described it in his journal as “…the most beautiful region… a vast forest of gigantic pines, intersected frequently with open glades, sprinkled all over with mountains, meadows, and wide savannahs…” In the past 100+ years, the region has changed drastically. The ponderosa pine forests once covered up to 25 million acres ranging from the south of British Columbia to northern Mexico, from the western Great Plains to the western coast, and were filled with old-growth trees that were up to 800 years old. Today, the ponderosa pine forests in the American west are mostly filled with younger trees, which are more vulnerable to wildfires than their old-growth ancestors. Throughout the late 1800s, the ponderosa pines were inordinately logged. They provided high yields of high-quality lumber, making them the first choice for builders in the frontier era, leaving other trees untouched until their regional supply of ponderosas was depleted. Like other pines, the ponderosa has struggled to return to its former state after a prolonged history with heavy logging and the more recent threat of invasive bark beetles. While the dolent loss of old-growth ponderosas is somewhat alleviated by the continued, fruitful natural propagation of young trees, we have only recently begun to understand the unique benefits of old-growth forests.

Old-growth forests in Utah are rare. Utah’s famous Pando, an aspen grove once thought to be the world’s largest living organism (now surpassed by a fungal mat in Oregon that spreads over 2,000 acres), is itself 80,000 years old, but no individual tree in Pando is older than 130 years, which excludes it from the old-growth forest category. Even the forests in Big Cottonwood Canyon and Little Cottonwood Canyon are comprised mostly of younger trees that took root after the mountains were nearly cleared by loggers. By the 1890s, Utah became a net importer of lumber, after having logged any and all suitable trees from the local area to supply the community’s growth. The forests that survived logging are in areas that were difficult to access during the state’s booming, industrial growth in the 1800s. Some of the most significant examples are forests of ponderosa pines located in the deserts of southern Utah, such as the stretch of old-growth trees in Dixie National Forest’s Red Canyon.

Fortunately, Utah’s forests are more protected than they have been historically, which hopefully means Utah’s future includes old-growth trees and the community who lives there at that time will reap the benefits of the work we put into ensuring at least some of our forests are well-protected today. Utah’s Division of Forestry, Fire, & State Lands implemented a new 10-year plan to revitalize the state’s forests in 2020, kicking off a new period of improved forest stewardship and protection. While the plan leaves a lot on the table, it’s one big step in securing a stable future for our state’s forests. Then, on a national level, the Biden administration recently sought out public input on old-growth forest conservation as part of Executive Order 14072: “Strengthening the Nation’s Forests, Communities, and Local Economies”, which will hopefully lead to even bigger steps towards greater protections for old-growth forests nationally and in Utah.

With efforts on the community, state, and national level, Utah’s future – albeit distant future – will include thousands of old-growth trees in state forests. Old-growth forests are key for sequestering carbon emissions – holding far more carbon than younger forests. They are also essential for maintaining a healthy water supply by storing and then gradually releasing clean water while also mitigating flood and fire impacts – all things that are desperately needed now and will be in even higher demand in the future. Our future generations need to the forests and so do future generations of wild animals and plants. Old-growth forests are required for the continued survival of thousands of species, without which Utah just wouldn’t feel like home. The remarkable wildlife that call Utah home need trees to survive and so do we.
