Arlington Cemetery Proposes Plan That Would Cut Down Almost 900 Trees
An expansion plan sparked some controversy at Arlington Cemetery when it was revealed that almost 900 trees would be cut down to make room for more burial plots. In response, a new plan was recently released by the Army Corps of Engineers to address concerns about razing so many century-old trees, but many people who opposed the original plan are still not satisfied. Although cemetery officials have promised to replace most of the trees that will be but down, the revised plan would only save eight of the historic trees.

New Jersey Is Declared Free From the Notorious ALB
Earlier this month, we posted on our blog about the damaging effects that Asian longhorned beetles can have on maple trees. Now, some good news has emerged from officials in New Jersey: The state has now declared itself free from the Asian longhorned beetle, an invasive insect that had plagued trees in New Jersey for more than a decade. In 2008, Illinois declared itself free from these beetles, making New Jersey the second state to eradicate this species.

China’s Demand for Disposable Wooden Chopsticks Could Be Putting a Strain on Forests

According to an article in Time, the demand for disposable chopsticks in China has increased dramatically, and more than 80 billion wooden sets of chopsticks are used and thrown away each year. The chairman of China’s Jilin Forestry Industry Group, Bo Guangxin, estimates that 20 million 20-year-old trees need to be cut down every year to satisfy this demand. Government officials are attempting to solve the problem by encouraging citizens to carry around reusable chopsticks.

U.S. Forest Service Develops Map to Illustrate Wildfire Risks
The Forest Service has developed a map that shows the wildfire risk to every state in the continental United States. The color-coded 2013 map shows the level of risk that a particular area is under for experiencing a wildfire this year, from a “very low” risk to a “very high” risk. Since the U.S. Forest Service ran out of money during last year’s fire season to combat dangerous wildfires, American Forests has signed a letter with other conservation groups to petition the U.S. Senate to allocate more funds for wildfire fighting programs.


Disappearance of the Monarch

What’s black and white and orange all over? Probably many things, but I’m thinking specifically of the monarch butterfly. Why? Because earlier this week, Mexico’s National Commission of Natural Protected Areas announced that the wintering population of the monarch butterfly declined by 59 percent this winter. The monarch — which can’t be counted individually, but whose population is measured instead by the amount of canopy covered while they are huddled together in the winter for warmth — occupied more than seven acres last winter and less than three acres this year.

This year’s figure represents the lowest number of butterflies in Mexico in the last two decades, when record keeping began, and the third year of declines. Lincoln Brower, a leading entomologist at Virginia’s Sweet Briar College, tells the Associated Press (AP) that “the report of the dwindling monarch butterfly winter residence in Mexico is ominous. This is not just the lowest population recorded in the 20 years for which we have records. It is the continuation of a statistically significant decrease in the monarch population that began at least a decade ago.”

For years, the monarch’s winter home in Mexico has been threatened by deforestation. At a peak in 2005, logging consumed more than 1,100 acres of areas in Michoacán, Mexico, where the butterfly winters. A year later, American Forests began work to restore oyamel firs in Michoacán to benefit the monarch; we’ve helped plant a million trees for the monarchs since 2006. The AP reports, though, that aerial surveys in 2012 revealed little logging in the monarch’s home, which has left some researchers looking at another culprit for the monarch’s decline: U.S. herbicide use.

Milkweed

During the migration from its summer homes in the northern U.S. and southern Canada to Mexico and back again, the monarch relies on milkweed growing throughout America’s agricultural fields for sustenance. However, herbicide-resistant crops have meant more herbicide use, which means very little milkweed peeking up between rows of corn and soybeans. Add in drought, and there are a lot of missing food sources for the monarch.

Chip Taylor, director the University of Kansas’ Monarch Watch, tells The New York Times that the butterfly migration is at a tipping point. If numbers continue to decline, the butterfly may not be able to readily recover from a natural disaster, such as an extremely harsh winter in Mexico.

The magnificent migration of the monarch butterfly is a wondrous, natural marvel, and its current precarious state is a prime example of how interconnected our natural systems are. Animals, insects, plants and trees flow from one ecosystem and habitat to another more rapidly than we sometimes realize. That’s why we’re focused not only on trees, but on the forests overall. If we protect them, we protect so much more.

 

 


At the Sign of the Flying Goose

Normally, geese fly south for the winter in flocks, returning in the spring and recognizable in their famous “v-formation.” But, there’s a singular goose that you can see flying solo year round in both Maine and Florida. You’ll see the same goose as far out into the Atlantic as the U.S. Virgin Islands and in the Pacific as far as Guam. This goose is in all 50 states and several U.S. territories.

It’s the flying goose emblem that signifies a national wildlife refuge.

The first refuge in today’s National Wildlife Refuge System was signed into being by President Theodore Roosevelt on this day 110 years ago. But while Pelican Island National Wildlife Refuge in Florida represented the first time land had been set aside as a refuge for a non-marketable species — the brown pelican — there was not yet a larger system for it to be a part of. Though more refuges would be set aside in the coming years, it would be decades until they were brought together under one system.

In 1921, a bill was introduced to establish a refuge system and create a one dollar hunting stamp to help fund it. The bill would be rejected four times until it finally passed in 1929 with the Migratory Bird Conservation Act. By then, however, reference to the hunting stamp had been lost. What’s known today as the duck stamp would have to wait until the 1934 passing of the Migratory Bird Hunting and Conservation Stamp Act. The Duck Stamp Act, as it’s better known, established the system of funding new wildlife refuges through revenue from hunting licenses.

In 1962, another act was passed that changed the National Wildlife Refuge System forever. The Refuge Recreation Act authorized recreational use of refuge lands so long as that recreation wouldn’t interfere with the refuge’s primary purpose of protecting species. The act was enacted largely due to public demand, but it has had positive conservation effects as well, giving more people the opportunity for wildlife- and wilderness-based educational activities, increasing public concern for conservation by bringing more people face to face with nature.

Today, the system includes 520 units and 93 million acres, nearly two thirds of which were added with a single act, the Alaska National Interest Lands Conservation Act (ANILCA) of 1980.

At American Forests, we collaborate with the U.S. Fish and Wildlife Service through our Global ReLeaf program to help keep our nation’s national wildlife refuges in good health. From our multi-year project in Hawai’i’s Hakalau National Wildlife Refuge during Global ReLeaf’s early years to our recent work reforesting 50 acres of wetlands in Wapanocca National Wildlife Refuge in Arkansas, we’re doing our part to keep that goose flying.


Remember the Longleaf

by Loose Leaf Team

By Josh DeLacey

When Alabama became a state in 1819, up to 90 million acres (140,000 square miles) of longleaf pine forests stretched across the southeastern United States. That’s an area almost the size of Montana — an area larger than all the national parks combined — all covered in towering pine trees. Early settlers described the forests as “limitless.”

Now, just two million acres of longleaf forests remain — less than three percent of the historic range — and less than half a percent of that is old growth. If you don’t want to do the math, there are just 12,000 scattered acres of old-growth longleaf left, down from 90 million. Because longleaf pines are slow growing, they produce strong wood, and because they consistently grow straight, they make ideal material for masts, telephone poles and beams. From the 1880s to 1920s, longleaf was heavily harvested, and by the 1930s, the forests were a fraction of their former size. This led harvesters and foresters to take action to try to help the longleaf, recognizing the importance of the species and its forest ecosystem.

Unfortunately, the two policies that were implemented actually harmed longleaf pines even further. First, harvesters began to rely on slash and loblolly pines. Although those species produced inferior wood, they did it cheaper, easier and quicker than the persnickety longleaf pine, which meant that while the longleaf was no longer being harvested, it also wasn’t being replanted through emerging sustainability practices.

I call longleaf pines persnickety because they require periodic groundfires in order to compete with other wildlife. And that leads to the second harmful policy: fire suppression. In the early and mid-20th century, the U.S. Forest Service prevented wildfires far too successfully for longleaf pines to thrive. So of the longleaf forests that once could have covered Montana, they now could only fill half of the state’s largest city, Billings.

As frustrating as that decimation is, it doesn’t stop with longleaf pines themselves. Longleafs provide huge benefits for their ecosystems, and without them, the nation is missing a very valuable resource.

Because here’s the thing about longleaf pines:

  • They support biodiversity. Nearly 600 species are associated with longleaf pine ecosystems. Half of those are considered rare, more than 100 are at-risk and 30 are threatened or endangered. Some of the best known of these species are indigo snakes, red-cockaded woodpeckers, gopher tortoises and flatwoods salamanders.
  • They provide erosion control. Longleaf pines can grow where other pines can’t, including sandy, dry and infertile soil or steep, mountainous slopes.
  • They’re durable. Longleaf pines are more resistant to diseases, insects, fires and storms than other southeastern pines. This makes them well-suited for climate change, ready to withstand extreme weather and climates.

American Forests is working on several programs to restore longleaf forests through Collaborative Forest Landscape Restoration projects and our Global ReLeaf work. For the last two years, we’ve partnered with Alcoa Foundation to plant longleaf pines near Charleston, S.C. For these projects, local Alcoa employees join other volunteers to help restore longleaf to their native habitat. And these are just a few of our longleaf projects.

So remember the longleaf pines and help us bring them back.


Where No Tree Has Gone Before

by Loose Leaf Team

By Tacy Lambiase

More intense wildfires, drought and drier soil — these are just some of the negative consequences of climate change that can seriously affect the health of trees. But what happens when warmer temperatures actually make certain ecosystems more hospitable for trees? According to a new study, the arctic tundra is one environment that won’t be treeless for much longer.

The arctic tundra, an ecosystem traditionally known for its lack of trees and shrubs, is undergoing a transformation. Over the past few decades, pine trees and large shrubs have begun to cover this once sparsely vegetated region. Using advanced climate models and satellite data, the authors of the new study in Nature Climate Change have concluded that Earth’s northernmost treeline is infringing on the arctic tundra.

“As a result of the enhanced warming … the total amount of heat available for plant growth in these northern latitudes is increasing,” Compton Tucker, an author on the study and a climate scientist at NASA’s Goddard Space Flight Center, tells Discovery News. “This created, during the past 30 years, large patches of vigorously productive vegetation, totaling more than a third of the northern landscape — over nine million square kilometers, which is roughly about the area of the USA — resembling the vegetation that occurs further to the south.”

Although many species of trees do not seem to be able to migrate fast enough to keep up with a changing climate, clearly some plants are successfully moving northward and thriving. But will this migration be ultimately beneficial for these trees? What about the landscape they’re changing?

As Discovery News points out, warmer temperatures do not necessarily mean more rainfall, especially in North America. If the arctic tundra becomes simultaneously warmer and drier, then some trees might not be able to survive there after all. The native vegetation and wildlife of the arctic tundra can also be negatively impacted by climate change. Since its small plants and mosses need cool temperatures and a wetter climate to survive, the arctic tundra may not be able to continue to support these species. Although it may seem like more trees in any part of the world is a positive development, broader effects of climate change could ultimately spell disaster for the natural ecosystems of our northern climates.

In addition, the arctic tundra might even contribute to exacerbating climate change. Much of the arctic tundra is covered in permafrost, or frozen soil, which releases carbon and methane into the air when it melts. If temperatures become too high for the permafrost to remain frozen, the amount of carbon released by melting permafrost will have a significant effect on the atmosphere, climate change and the ecological make-up of the tundra.

The arctic tundra is a beautiful, but complex ecosystem. As scientists continue to study the effects of climate change, it will be important to keep this particular habitat on our radars.


The Sequestration and Conservation

by Loose Leaf Team

By Michelle Werts

A little more than a week ago, the long-dreaded budget sequestration began, which is forcing all federal agencies to make five percent budget cuts to all of their programs, activities, etc. And as we’ve all been seeing in the news, five percent might seem like a small number, but it can have big impacts. For instance, my bus friend (that person you only ever see and talk to while commuting to and from work) mentioned that the topic of furloughs for him and his fellow employees has already been broached. This immediate loss of livelihood is one of the most obvious, tangible effects of sequestration, but its tentacles are actually everywhere.

Let’s start with our beloved national parks. Alison’s recent post outlined how a sequestration will affect visitor services at famous landscapes like Yellowstone and the Grand Canyon, but what about the local economies that rely on those parks? Last month, the National Park Service revealed that visitors to national parks generated $30.1 billion in 2011. More than a third of this spending — to the tune of $13 billion — went directly into local economies within 60 miles of the parks. For every $1 invested in our national parks in 2011, $10 were returned. So if reduced hours of operation and services due to sequestration lead to reduced national park visiting, ripples will be felt for miles.

Next up: fire. In 2012, more than 9.3 million acres burned in wildland fires, which is 28 percent higher than the national 10-year average. More than 4,000 structures were destroyed in 2012 wildfires, compared to the average of 2,700 per year! As you can imagine, all of this led to more requests for firefighting resources than the average — resources that are funded through federal agencies, specifically the U.S. Forest Service. A five percent cut could mean less funds to fight wildfires in 2013, or it could mean other programs may suffer as funds have to be moved to cover firefighting. Both are losing scenarios.

And I don’t even know where to begin with conservation programs across the agencies, as sequestration is going to significantly impact so many programs. Maybe just a few examples from our near and dear U.S. Forest Service (USFS) will suffice.

  • The Lost Trail Powder Mountain Ski Area within Montana’s Bitterroot National Forest

    USFS issues special permits every year for specialized recreation on public land, such as ski areas and outfitter-guides. With budget cuts, USFS estimates it would only be able to manage half of its normal permits, affecting the 122 ski areas and 5,000 outfitter-guides, not to mention others.

  • USFS’ Legacy Roads and Trails program creates or retains between 810 and 1,296 high quality jobs in rural America each year. These individuals help with water quality, fish habitat and recreation sites in national forests. It’s estimated that for every $1 million cut for this budget, anywhere between 15 and 24 jobs will be lost. With an FY12 budget of only $45 million, a five percent cut means 30 to 48 jobs are on the line.
  • With cuts to the Urban and Community Forestry Program, the ability of local communities, tribes and nonprofits across the country to conserve thousands of acres of forests would be compromised, and these cuts would mean reduced resources to help thousands of communities and towns to manage, maintain and improve their tree cover and greenspaces.

I think we get the picture. Although, for a complete, disheartening look at all of the conservation programs and how they will be impacted by the sequestration, head over to our Policy page.

Our country is in a tough financial jam and cuts may need to happen, but shouldn’t they happen with some concerted thought and planning? Conservation programs represented a measly 1.26 percent of the federal budget in 2012. Is a five percent sweeping cut across them all the best course of action? Let’s hope the continuing resolution proposed by Senate Appropriations Committee Chairwoman Barbara Mikulski (D-MD) that is expected to go up for a vote this week gains some traction because while the cuts would still be present, the Senate continuing resolution would at least allow the agencies to decide where they’re made. I would surely rest easier to know that experts are deciding the fate of conservation, as opposed to blind cuts.


A Menace to Maples

If it wasn’t enough of a threat to America’s sweet tooth that climate change may affect maple syrup yields in the next 50 years, the sugar maple is facing another threat as well — an invasive pest. We’re wrapping up Invasive Species Awareness Week by shining the spotlight on a tiny pest with big consequences: the Asian longhorned beetle or ALB.

ALB is a black beetle between one and one-and-a-half inches long, with white spots and — as its name implies — two antennae that are even longer than its body. In addition to recognizing the beetles themselves, you can also spot them by signs of occupation on the tree. In early autumn, females dig out oval depressions in which to lay their eggs. When the larvae hatch, they burrow into the wood to feed and grow through the winter. In spring, they emerge as adult beetles, leaving tell-tale, dime-sized holes behind them.

ALB most likely arrived by way of wooden packing crates from their native range of China and parts of Korea and Japan. Their presence has already cost the U.S. tens of thousands of trees and hundreds of millions of state and federal dollars, and that’s just in the few states where they’ve established themselves so far: New York, New Jersey, Massachusetts and, previously, Illinois. If they get a chance to spread throughout the country, they have “the potential to cause more damage than Dutch elm disease, chestnut blight and gypsy moths combined” and kill 30 percent of the country’s hardwoods, according to the U.S. Department of Agriculture.

The maple industry, in particular, is worried. This $41 million industry has already been affected in Massachusetts, where more than 60 square miles are under quarantine, and nearby Vermont and New Hampshire are keeping a close eye for signs of the bug. Sugar and other maples also give us some of the most vibrant fall colors. One million tourists flock to New England to leaf peep every fall, bringing a billion dollars in tourism revenue with them, all of which could be at the mercy of ALB if it continues to spread.

What’s more, while maples appear to be a favorite of the beetle, they are not the only trees in danger. Unlike some pickier beetles, ALB enjoys a wide variety of deciduous hardwood trees, including ash, birch, elm, poplar and willow. This means that the maple-dependent industries will not be the only ones in danger. ALB could have far-reaching consequences for the lumber and nursery industries, too.

But there is hope. ALB has already been eradicated in Illinois and in certain counties of New Jersey and New York.

What can you do? Using local firewood is one of the most important ways to prevent the spread of ALB and other invasive pests. Check out http://www.dontmovefirewood.org/ to learn more.


Invasive Species: How You Can Help

by Loose Leaf Team

By Tacy Lambiase

As Monday’s blog post showed, invasive species can be really bad news for our country’s native plants and animals. From white pine blister rust in the West to the emerald ash borer devastating trees across the Midwest, nonnative species can throw ecosystems completely out of balance.

But what can be done to stop these species from getting out of control? What can individual people do to help? In honor of National Invasive Species Awareness Week, we’ve compiled a list of simple steps that you can take to prevent the proliferation of invasive species.

  • Volunteers remove water chestnut, an invasive species, from Oxbow Lake in Massachusetts.

    Plant native species of trees and shrubs on your property. Although some plants may look aesthetically pleasing, they are not always beneficial to the local environment. In addition to preserving your lawn’s soil, consciously choosing to landscape with native plants will make your yard into a suitable habitat for birds and other wildlife. Visit the U.S. Department of Agriculture’s website to find out what nonnative species may inhabit your backyard already.

  • Get involved with a local effort to remove invasive species. Many environmental groups organize events for volunteers to help remove invasive plants from parks or other wild areas.
  • Never release pets or exotic animals into the wild. Recently, scientists have discovered giant goldfish living in Lake Tahoe. It is believed that these fish ended up in the lake after people dumped the contents of their aquariums into the water. Now that these goldfish are eating large amounts of smaller fish, they are threatening to disrupt the natural food chain of Tahoe’s ecosystem. If you ever need to find a new home for an animal, contact a local rescue group or nature center.
  • After spending time in nature, be sure to clean off the outside of your boat or camping equipment. Invasive plants and seeds can become easily trapped in outdoor recreation gear, and you could accidentally help them spread to new environments.

Finally, you can support organizations that work to combat invasive species. Since 2011, American Forests has been working to protect Lake Tahoe’s forests against white pine blister rust. Although sugar pines used to cover the region, they now account for less than five percent of the tree cover around Lake Tahoe because of this invasive fungus. American Forests also supported a project in Chippewa National Forest in Minnesota to reforest an area with native plants that had been overrun by nonnative plant species, including tansy and honeysuckle.

By becoming educated about invasive species, we can all take action to mitigate the serious effects they can have on our environment.


Revitalizing Los Angeles’ Backyard

by Loose Leaf Team

By Michelle Werts

For many Americans, spending time in a forest is a time-honored getaway:

  • 42.5 million Americans or 15 percent of the U.S. population older than age six went camping in 2011.
  • 67 percent of those campers camped in public campgrounds, like those of local, state and national parks and forests.

Sometimes, though, our favorite getaway sites get caught in the path of forces bigger than themselves, which is what happened to popular picnic sites in Angeles National Forest in 2009. A wildfire known as the Station Fire consumed 25 percent of the national forest, damaging many of the picnic areas. These areas are a popular site for relaxation, as they are less than hour away from a majority of the L.A. Basin’s 17 million residents.

To help restore the Wildwood Picnic Site, Stoneyvale Picnic Site, Hidden Springs Picnic Site and Delta Flats Day Use Area in Angeles National Forest, American Forests is partnering with Alcoa Foundation to plant a combination of coast live oak, canyon live oak, Douglas-fir, arroyo willows and cottonwoods.

Working alongside Alcoa employees and the National Forest Foundation, this project is strengthening more than just recreation areas. It’s also restoring riparian areas to help maintain a healthy local watershed and is fostering forest stewardship through four volunteer tree planting days. This project, like so many of our Global ReLeaf projects, illustrates how much can be achieved when we join together to help the environment.

Last week, I participated in a workshop titled “Urban Forestry: Toward an Ecosystem Services Research Agenda” at the National Academy of Sciences in Washington, D.C. The workshop brought together more than 100 participants, and many more tuned-in via webinar. What a great turn out!

With interesting presentations, discussions and networking opportunities, I was excited to participate and hone in on the workshop’s key objectives to:

  • Explore the role of trees within the greater urban ecosystem and the linkages/trade-offs among different types of ecosystem services within this larger context.
  • Review our current understanding of the different types of ecosystem services provided by urban forestry, and discuss research needs for improving this understanding.
  • Highlight key tools available to track and quantify ecosystem services, and identify gaps in our ability to model, measure and monitor such services.
  • Identify effective management strategies and key challenges in implementing successful urban forestry programs.
Eco-Health Relationship Health Science Browser

The U.S. Environmental Protection Agency’s “Eco-Health Relationship Health Science Browser”: http://www.epa.gov/research/healthscience/browser/

One main outcome that I enjoyed from this workshop was the update on all sorts of cool tools that are out there to help us talk about the ecosystem services provided by urban forests. For example:

  • Laura Jackson, a research biologist with the U.S. Environmental Protection Agency’s Office of Research and Development, presented the “Eco-Health Relationship Health Science Browser.” This tool highlights the urban ecosystem and all the related public health benefits. Take a stroll around this interactive tool and see what you can learn.
  • Dave Nowak, a project leader for the U.S. Forest Service’s Northern Research Station and an American Forests Science Advisory Board Member, discussed some of the new features of the recently launched i-Tree v5.0. The i-Tree suite provides urban forestry analysis and benefits assessment tools. The new i-Tree v5.0 features lots of great things, including a web-based data collection system (you can now use your smart phones to collect data with i-Tree!), pest risk analysis and updated ecosystem services pollution and carbon valuations. Check out all the new things!

In addition to the talk about tools for ecosystem service evaluation, there were also great discussions about improving the management of urban forests. One especially interesting presentation was from Morgan Grove, a social ecologist and team leader of the U.S. Forest Service’s Baltimore Field Station, who pointed out that “there is more woody biomass coming out of urban forests than natural areas.” With much of this due to trees being removed in communities due to severe weather events or damage from invasive pests, we need to find a way to better manage those results. Offering suggestions and a framework to maximize the biomass from our urban forests, he has been working to develop an interesting project in Baltimore for “Rethinking Wood in the City.”

I look forward to catching up on all the presentations that I missed the first day of the workshop that discussed current research on topics such as the role of urban forestry in public health, in sustaining biodiversity, in stormwater management and in air quality. So many great topics and important research underway!

Stay tuned for the final report that will be produced by the National Academy of Sciences based on the results of this workshop and the state of the urban forests ecosystem services research agenda. As an urban forest practitioner, tree planter, environmentalist or just interested community member, what type of research would you like to see prioritized to help enhance and improve our urban forests?
