Celebrating World Environment Day

by American Forests

By Michelle Werts

Today marks the 40th World Environment Day.

Started in 1972 by the United Nations, World Environment Day aims to be “the biggest and most widely celebrated global day for positive environmental action.” Each year, the United Nations Environment Programme (UNEP) chooses a theme to help focus its environmental message around World Environment Day and the rest of the year. This year, that theme is “Green Economy: Does it include you?”

And while the phrase “green economy” might not scream forests, forests are actually an important element of the world economy. According to UNEP’s Green Economy report on forests:

Forest goods and services support the economic livelihoods of over 1 billion people, most of whom are in developing countries and are poor. While timber, paper and fibre products yield only a small fraction of global GDP [Gross Domestic Product], public goods derived from forest ecosystems have substantial economic value estimated in the trillions of dollars. Forests sustain more than 50 percent of terrestrial species, they regulate global climate through carbon storage and protect watersheds. The products of forest industries are valuable, not least because they are renewable, recyclable and biodegradable. Thus, forests are a fundamental part of the earth’s ecological infrastructure and forest goods and services are important components of a green economy.

For instance, in Nepal, 35 percent of the country’s citizens are involved in managing forests under community forestry practices. As a result, those involved receive employment and income through everything from protecting the forest to tree felling and log extraction to the use of non-timber forest products. And community forestry groups have been known to develop scholarship programs and provide savings and credit opportunities. All of this while Nepal’s forests now grow by 1.35 percent per year compared to a declining rate of 1.9 percent in the 1990s.

So what does this mean? If we protect and properly use our forests, they will protect and help people around the world, providing jobs while keeping our environment cleaner. Green economy indeed.

But the conversation doesn’t end today. Later this month, leaders from around the world will gather in Brazil for the Rio+20 Summit, which will continue the focus on creating a worldwide green economy to help combat global issues like the financial crisis, food crisis, ecosystem degradation and more.

Twenty years after the landmark 1992 Earth Summit, where countries adopted “Agenda 21” — a way to rethink economic growth, advance social equity and ensure environmental protection — the UN is bringing the world together again to address the major environmental issues of the day. It is once again an opportunity for concerned citizens, officials and leaders to influence how we want to shape our future. And considering the daily scientific reports of unsettling things happening in nature, in our cities and around the world that can be connected to the environment, there is no time like the present to start protecting that future.

More Trees, Please

by American Forests

By Katrina Marland

Across this blog and throughout the American Forests website, you can find a wealth of information about the various and sundry benefits that trees can provide — from the physical (cleaner air) to the economic (higher property value). Trees can also tell us a lot of things, whether it is the inconsequential cliché etched in their bark that “Jimmy loves Sally” or the more important (at least scientifically) history of a region’s climate. And, as pointed out recently by another blogger, trees can also tell us how wealthy a neighborhood is — from space.

In his blog, Per Square Mile, Tim DeChant discusses a 2008 study published in Landscape and Urban Planning that worked to better understand the relationship between income and tree cover in U.S. cities. What it found is that even small increases in income would increase an area’s tree cover. Similarly, even small decreases in income correlate to a decrease in tree cover. To put it simply: more money equals more trees. In his blog, Tim illustrated this point through satellite photos of high- and low-income neighborhoods. Sadly, you don’t have to look hard to see which ones are greener.

Another example can be found in the areas around Boston. Here is Somerville, Massachusetts:

And here is the wealthier area of West Cambridge.

The reasons behind this connection are many. Homes with higher income generally have more land and, therefore, more space for trees. Since trees can have a tougher time growing in urban settings, they’re also more expensive to obtain and care for, which means an urban tree canopy can be considered a luxury not all neighborhoods can afford. However, looking at trees as a luxury is a pretty one-dimensional view. Yes, they’re pretty, but they also provide a host of benefits, particularly in urban settings — benefits that people in high-income areas may enjoy, but that could also work to significantly improve the lives and livelihoods of people in low-income areas, like better air quality (particularly important for those who can’t afford good healthcare), higher property values and even lower crime rates. Cities always seem to have one plan or another to improve life for neighborhoods in need, many of them costly and cumbersome. Trees certainly don’t hold all the answers, but if given a chance, a touch of Mother Nature may be able to make a great deal of difference.

Take a Hike

Tomorrow, Americans across the country will be celebrating the 19th annual National Trails Day, which was started by the American Hiking Society back in 1993 — but the idea of a day for celebrating America’s hiking trails actually goes farther back.

In 1987, President Ronald Reagan’s President’s Commission on Americans Outdoors recommended that every person in the country should be able to walk out their front door and reach a trail within 15 minutes. While this might not be a reality for every American yet, the country does boast 200,000 miles of hiking, biking and other types of trails that can be enjoyed tomorrow — and every day. And the benefits they provide are never-ending.

First, there’s the obvious: Physical activity is good for you. Getting out and hiking or biking along a recreational trail helps keep your body in shape. Plus, as featured in American Forests, studies show that being amidst forests helps reduce stress, lower blood pressure and strengthen immune systems.

And, now, a new study is revealing that not only is traipsing through nature good for your body, it’s good for your brain. The study conducted by the University of Kansas’ Ruth Ann Atchley reveals that hikers who have been on a trail for four days are 50 percent more creative than those who haven’t been communing with nature. So get out and enjoy some of America’s trails to benefit your mind and body!

Where to go?

Well, there’s always the Triple Crown of long-distance hiking trails:

  • The Appalachian Trail – 2,000 miles that stretch from Georgia to Maine
  • The Pacific Crest – 2,600-plus miles that traverse the Cascade and Sierra Nevada Mountains from British Columbia down to California
  • The Continental Divide – 3,000 miles along the famous divide from Montana to New Mexico that takes travelers to high-altitude peaks in the Rockies

… or, you can head to some of American Forests’ Best Hiking Trails in the U.S.

… or, urban dwellers can check out National Geographic’s list of the best hiking cities for trails ideas. They also have a list of the best trails in national parks.

… or, you can simply go through your front door and just keep walking. Big trail, small trail, no trail, sidewalk or other walking surface, the spirit of National Trails Day is just to get out and enjoy nature. I’ll see you there.

Smoggy Sequoias

by American Forests

More often than not, you expect a park or forest to have pretty clean air. Even more so if it happens to be a well-known place, located far from the nearest urban center that could be smogging up its air. But sadly, this is not always the case. Sequoia National Park, home to some of the biggest and oldest trees in the U.S., is also home to a higher level of air pollution than any other national park.

There are 52 national parks in the U.S. that monitor their air quality each day to make sure that it is safe for visitors. High temperatures, levels of smog and levels of certain allergens or pollutants can all add up to make a bad air-quality day. Ozone in particular can be a nasty problem, capable of literally causing lungs to blister when it’s found at high enough concentrations. That national parks — the places we go to get away from cities and their many urban problems — also have to monitor for air pollution is a bit alarming. This week, the EPA and the National Park Service released a list of the 10 national parks with the worst pollution in 2011 based on ozone levels and days that failed to meet EPA standards for air quality, and Sequoia National Park topped the list.

Despite its reputation for immense trees and remote forests, Sequoia had a total of 87 days that failed to meet federal air-quality standards in 2011 — and it’s hardly a new problem. Park employees and volunteers have come to expect regular lectures on the dangers of air pollution and watch as once-clear vistas have become routinely wreathed in smog. In fact, according to the National Park Conservation Association (NPCA), Sequoia National Park has levels of ozone comparable to those in major cities like Los Angeles. Already this year, though summer has just begun, the park has seen levels of ozone well beyond those set by federal health standards.

How can this be the case when the park is miles away from the closest city? Unfortunately, it comes down to a quirk of geography. The park lies north of the San Joaquin Valley, which contains several major trucking highways, a number of power and food-processing plants and acres upon acres of farmland overseen by diesel-powered machinery. Pollution from this region is pushed north by winds off San Francisco Bay and meets the cooler air moving south, creating an eddy that traps the polluted air in the region, which gives it a chance to seep into the area where the park is located.

Human safety is certainly important, but such severe air pollution in what is supposed to be a remote, natural location also begs the question, what about the trees? Scientists are uncertain what effect long-term exposure to these levels of ozone might have on the environment in these locations, though foresters do see needles turn yellow as the trees soak up ozone, which interferes with their ability to photosynthesize. Young seedlings also struggle to survive and grow with such obstacles to overcome.

With this disturbing news about air pollution in national parks, we can only hope that Sequoia and other parks will benefit from legislation like the Clean Air Act, through which officials aim to give the region pure, clean air by the year 2064. The problem is that the only way to cut down on the pollution that enters Sequoia is to cut down on the pollution in the entire San Joaquin Valley air basin — a tall order given the sheer number of sources of pollution.

(500) Jobs of Summer

Memorial Day weekend is viewed as the official kickoff of summer. This past weekend, many folks headed to the beach or gathered at backyard barbeques to celebrate the holiday. It’s also the time of year when schools let out, and young people start looking for summer jobs. But unlike the flocks of interns that flood D.C. in the summer, some young people are planning to spend their summers working outside. Thanks to a new federal grant program, there are even more opportunities for youth to work outside this summer. With $3.7 million available for conservation projects, the grant will help employ more than 500 youths over the summer, adding to the existing 20,000-plus youth summer employment opportunities in national forests, parks and wildlife refuges.

Since President Obama launched his America’s Great Outdoors Initiative back in 2010, conservation and outdoor recreation have been highlighted as ways that we can protect our natural heritage. The U.S. Department of Agriculture (USDA), U.S. Department of Interior (DOI), U.S. Environmental Protection Agency (EPA) and the Council on Environmental Quality (CEQ) worked together to develop a conservation action plan after receiving more than 100,000 public comments.

In response to the Obama administration’s call to expand youth engagement in the outdoors, DOI Secretary Ken Salazar, USDA Secretary Tom Vilsack and CEQ Chair Nancy Sutley recently announced the creation of a new competitive grant program to expand the summer youth corps on public lands. The grant program is part of a new Youth Initiative funded through the Bureau of Land Management (part of DOI), the National Fish and Wildlife Foundation, the U.S. Forest Service and private partners from the America’s Great Outdoors development initiative. The initiative’s website serves as an educational resource for youth, provides an events calendar to find local opportunities to engage and even has an online job search available.

Secretary Salazar noted the importance of engaging young people in working on public lands and developing the next generation of land stewards: “President Obama’s call to expand summer job opportunities for young people is helping us engage and train the next generation of natural resource professionals and build a workforce that represents all of America.” So, whether it’s indoors or outdoors, an intern at an environmental nonprofit or working in a national forest, it’s encouraging to see how summer jobs are shaping the future of conservation.

Geology vs. Ecology

by American Forests

By Michelle Werts

Thirty-two years ago this month, Washington’s Mount St. Helens erupted and collapsed, creating a massive avalanche and a stone- and ash-filled wind that would decimate the surrounding countryside. Nearly 150 square miles of forest were destroyed almost instantly — and then the eruption continued for nine hours. What was once a lush, green landscape was now a barren, gray landscape, but over time the green has slowly returned to Mount St. Helens, as evidenced in this recently released Landsat timelapse from NASA’s Goddard Space Flight Center.

Note: The red in the first few years is how Landsat used to register vegetation.

As shown in this photo taken after the eruption (use the sign as a comparison point between the two photos), Mount St. Helens’ eruption destroyed the old-growth forest.

Through this video, you can see how vegetation has slowly returned to the Mount St. Helens area while the surrounding areas have been constantly evolving, as well. And for 30 years, scientists have been studying the area around the famous volcano to gather new insight into how areas recover from such catastrophic events. Here are some highlights of what they’ve learned:

  • Legacies can regrow a forest: At the time of the eruption, scientists believed that Mount St. Helens’ ecology would renew the barren landscape with help from species once unknown to the area. Some did, but much of the regrowth can also be attributed to “biological legacies” — the fallen trees, buried seeds and amphibians that survived the blast and have been resilient restarters of the green spaces around the volcano.
  • Thousands of acres of dead trees don’t necessarily equal fire and insect outbreaks: Many advocated for rapid salvage logging of the trees destroyed by the eruption, but in the 110,000-acre Mount St. Helens National Volcanic Monument created in 1982, no such logging was completed — and no massive fire or insect outbreaks occurred. It turns out that volcano ash reduces flammability and repels insects.
  • Native is better: Non-native seeds were spread around Mount St. Helens to help minimize erosion, but it wasn’t very successful. However, natural revegetation was successful in the area, showing that native seeds should always be considered first for erosion control efforts.

While 30 years might seem like a long time and many plants, trees and animals have repopulated this once-ravaged landscape, in ecological terms, recovery has only just begun. It’ll take centuries for the old-growth forest of firs (like Pacific silver and Douglas-fir) and hemlocks to regenerate fully. It’s amazing how one geologic event — a 5.1 Richter-scale earthquake that shook the volcanic mountain, causing the collapse and eruption — can destroy centuries of ecological work. And, it serves as a lesson that once destroyed, nature is not always easy to replace, but the Mount St. Helens area is making a mighty attempt.

At Crater Lake

by American Forests

By Katrina Marland

When I was seven, my family took the first of many summer vacations traveling through the Pacific Northwest. We camped, hiked, fished and traveled to all kinds of places — from caves to redwood forests to rocky beaches. Some sites we saw only once, others we liked so much that we returned each year. Though I loved every one of these trips, no single experience had quite the impact as the first time I saw Oregon’s Crater Lake. My family reached the viewing point along the rim; I looked out at the immense scene before me and was completely, breathlessly awestruck with the size of it all. Knowing little about natural history at the time, all I knew was that at some point, somehow, nature made all this.

Crater Lake

Earlier this week, Crater Lake National Park (CLNP) celebrated its 110th anniversary. Established May 22, 1903, the park covers more than 183,000 acres around Crater Lake itself. At less than six miles across, the lake certainly isn’t the largest in the U.S., but with a depth of 1,943 feet, it is easily the deepest. In fact, it is one of the 10 deepest lakes on the entire planet. The blue water that the lake was once named for — so clear because the lake is fed almost solely from snowfall — sits inside a massive crater that formed roughly 7,700 years ago when the stratovolcano Mount Mazama erupted and collapsed. The resulting crater is so deep that the lake itself only begins more than 2,000 feet below the crater rim. So when you look down into the lake, you look way, way down — so far that it seems impossible.

The rim itself sits at about 7,000 feet above sea level, so if you manage to turn your back on the sight of this lake that seems to sit on the top of the world, you still have a fantastic view of the rest of the Cascades sprawled out around you — much of it more pristine than you could hope to see. Because the park was established, and therefore protected, before commercial logging reached the area, almost all the forests on CLNP are old growth. At the high altitude and with the inhospitable soil that comes from taking root in an area with so much volcanic activity, many of the trees that you can see from Crater Lake have fought to be there for longer than most of us have been alive. So while you may visit to see the lake itself — and I strongly suggest you do — don’t forget that it sits amidst a landscape carved out by raw, natural energy and covered with some of the most determined life on the planet.






Trees Can’t Swim

by American Forests

By Michelle Werts

Martha’s Vineyard. It’s a place I’ve always associated with vacation cottages and well-to-do New Englanders. Little did I know that this set of islands off of Cape Cod, Massachusetts, is actually a hotbed for forest researchers, who are studying some interesting phenomena on this idyllic locale.

First, there’s the case of the forest consumed by the sea. Since an April 2007 storm breached Norton Point Beach — the storm cut this barrier beach in half — the ocean has been eating away the beach and land at Wasque Point, aka the southeast corner of Chappaquiddick Island. With the beach now gone, the waves are attacking the bluffs — and the pitch pine forest that grows there. As the bluffs go, so do the pitch pines, tumbling into the ocean currents below. And as Harvard Forest Director David Foster told the Harvard Gazette, pitch pine forests are “very salt tolerant, but they’re not that salt tolerant.”

Foster, a paleoecologist who studies how landscapes change over long periods of time, plans on bringing research fellows and students to Wasque this summer to study how this environment is rapidly changing thanks to one destructive storm and the power of the ocean. As The Trustees of Reservations Director Chris Kennedy, whose conservation group manages the area around Wasque Point, told the Vineyard Gazette, “There’s nothing to block the waves. … They’re crashing right against the cliffs, which are just sand. So we can lose 10 to 15 to 20 feet overnight.” At other points in the area, the surf is adding feet of sand to the beaches and is creating a myriad of sandbars offshore. Kennedy expects that in two to five years that part of Norton Point Beach that is migrating west parallel to the shore will reconnect to the island and hopefully reduce the extreme erosion.

This isn’t the only drastic change to Martha Vineyard’s landscape in the 21st century. In 2007, the island’s Polly Hill Arboretum experienced a massive oak die-off, and according to Foster, this wasn’t the first time that the Vineyard’s oaks died en masse — it had happened 5,000 years earlier. Foster and other researchers had previously studied a massive oak die-off on the island and determined that 5,000 years ago, the oaks succumbed to a warming period in Earth’s history and were replaced by beech trees that flourished for 1,000 years before the oaks were able to reassert themselves. The 2007 die-off, according to Foster, appears to be following that pattern, as insects — which were likely more prevalent due to a warming climate — attacked the trees for three consecutive years before the oaks lost the battle. Now, five years later, history continues to repeat itself as where once oak trees stood, young beech trees are rising in their place.

So, Norton Point Beach will attach itself to Wasque and thus slow the erosion that is decimating the coast, and Martha Vineyard’s birch trees, bushes and shrubs are sprouting up to take the place of the forests that were lost. We get two prime examples of how nature is always changing and always evolving — they just both happen to be on the same tiny set of islands. Astonishing.

Trees Make Urban Communities More Livable

by Amanda Tai

I’ve already talked about the importance of trees in urban areas and the many benefits they provide — like increased opportunities for outdoor recreation, community economic growth and improved air quality. Now, the buzz around urban forests has reached the ears of Congress with the Urban Revitalization and Livable Communities Act, H.R. 709. The bill’s language requires the Department of Housing and Urban Development to establish and administer a grant-giving program for park and recreational projects in urban areas. Many types of projects could be funded by this program, like planting trees in an abandoned lot to turn it into a community green space or engaging inner-city youth in outdoor recreation. The bill would appropriate $445 million per year to the program through fiscal year 2021. This funding would not only create an immediate impact, but would also establish an investment in the future of urban communities and recreation. To be eligible for a grant, applicants would have to submit a five-year plan indicating their commitment to maintain and monitor their project.

This isn’t the first time there has been a bill supporting urban restoration work. In 1978, the Urban Park and Recreation Recovery (UPARR) Act established a program that provided matching grants for restoring distressed urban areas. UPARR hasn’t been funded since 2002, but the facilities and sites it funded are still in use today and remain protected under the act’s provisions.

While urban parks and recreation may exist on Congress’ radar, it’s still only a faint blip. The Urban Revitalization and Livable Communities Act has sat around with no movement for the past two and a half years. First introduced in 2009 by Representative Albio Sires (D-NJ), the bill was referred to committee, but never moved on to a full House vote. In February 2011, Sires reintroduced his bill in a second attempt to build congressional support. Groups like the Urban Parks Coalition and the Sustainable Urban Forests Coalition — of which American Forests is a member — are advocating for the passage of this bill, which has currently been sent to House subcommittees to await further action.

We all know it’s tough to get any movement in Congress these days, but urban forest advocates continue working so that they’ll be ready when the ball starts to roll again. Keeping the discussion alive will show Congress that funding for urban parks and forests is a priority issue. After all, many members of Congress live in the D.C. metropolitan area. I imagine they’ve seen and enjoyed the trees and parks near their houses. That brings the issue is a lot closer to home than Congress may realize.

Law in the Amazon

Welcome back to the world of environmental law and policy! Most of these posts will address domestic concerns, but today, we begin with one of the largest forests in the world — the Amazon rainforest. In the vein of Harper’s Index, one of my most favorite monthly reads, I bring you a few interesting statistics:

  • Number of acres of forests and grasslands managed by the U.S. Forest Service: 193 million
  • Number of acres of rainforest in the Amazon Basin: approximately 1.4 billion
  • Percentage of the rainforest that is solely within Brazil: 60 percent, or approximately 840 million acres
  • Number of law enforcement personnel employed by the U.S. Forest Service: 737
  • Average number of acres of forest and grassland per agent: 261,872
  • Number of federal environmental enforcement agents in Brazil: 1,300
  • Average number of acres of Brazilian rainforest per agent: 646,153

The U.S. Forest Service also has a stewardship role, in conjunction with state and local authorities, over millions of acres of urban forests. The Forest Service has firefighters and numerous other types of employees; however, the fact remains: In Brazil, enforcement agents have much more territory to cover than their counterparts in the United States. That territory is not grassland or forests with roads and paths and trails. The Amazon rainforest contains one in 10 known species of plants and animals in the world. It is dense and, in large part, unmapped. Both farmers and ranchers own land within the rainforest, and Brazil has passed laws and regulations governing how that private land is cultivated. One of those regulations requires farmers to preserve or replant trees on 80 percent of their land that is located within the Amazon rainforest. Trees and woodlands that border rivers and stand on hilltops and steep inclines are not included in the total amount of required preserved forestland.

On April 25 of this year, the Brazilian Congress passed a new bill that pitted the agricultural lobby against environmental groups, coupled with a large dose of governmental jostling. This bill, which underwent a significant alteration by lawmakers to include more lenient language on behalf of the agriculture lobby, allows previously exempt woodlands to be counted in the total amount of acreage required by law to be preserved. Farmers who had deforested land in order to create arable land for agriculture can now replant less acreage, but still comply with the overall requirement of 80 percent preservation. The new bill also allows farmers to cultivate farmland up to rivers’ edges, should they choose to do so. Previous buffer zones of 30 to 100 yards of forest required between the river and worked land were stripped away by the new bill. Finally, the bill grants an amnesty for fines levied against farms and ranches that had previously cleared more than the legally allowed amount of acreage.

Environmentalists decry the new bill as too lenient in terms of preservation and restoration and call the amnesty a free pass for environmental crimes. The main fear of the bill is that it will result in the replanting of fewer deforested acres than under the old regulations.

In June, the United Nations Conference on Sustainable Development (the Rio+20 Summit) descends upon Brazil to discuss global environmental policy. This new forest bill, watched closely by other developing nations, will surely be a topic of conversation among the attendees, especially considering the summit’s themes of poverty eradication through sustainable development and the creation of an institutional framework for that development. Brazil faces innumerable challenges when it comes to its rainforest. And the trials that the nation must undertake in balancing the various interested factions can serve as an education for us all.
