When settlers first came to what is now the southeastern U.S., they were greeted by vast pine forests — the southern longleaf pine. They noticed its spirituality, its majesty, its wildlife and its old growth trees often leaning to one side with weight.

Naturalist John Muir spent time there observing these great forests:

“In ‘pine barrens’ most of the day.  Low, level, sandy tracts; the pines wide apart; the sunny spaces between full of beautiful abounding grasses, liatris, long, wand-like solidago (goldenrod), saw palmettos, etc., covering the ground in garden style. Here I sauntered in delightful freedom, meeting none of the cat-clawed vines, or shrubs, of the alluvial bottoms.”

In colonial times, the longleaf turned out to be very valuable for lumber and for the pitch, tar and turpentine made from the trees and believed to be the origin of North Carolina’s moniker, “Tar Heel State.” Eighteenth-century ships were made entirely of wood, and North Carolina was called upon to provide so-called “naval stores” including tar, pitch and turpentine that were used to keep ship bottoms waterproof and afloat.  All from pine trees, North Carolina became a key supplier to the British Navy.

Of course, much has changed in the South over the last 500 years. A survey conducted in 1996 by a Florida researcher found that less than 0.01 percent of the remaining longleaf pine forests could be considered old growth. This handful of virgin forests is a draw for scientists, serving as a benchmark for conditions prior to European settlement.

Now efforts are underway to preserve the old-growth longleaf pine forests and provide for planting new trees. This is especially beneficial for the red-cockaded woodpecker, an endangered species found mainly in mature long-leaf pine forests in southern states. Only about one percent of their original range remains. Longleaf pine communities may have covered some 92 million acres, but now fewer than 3 million acres remain.

American Forests is partnering with the U.S. Forest Service to replant an area of the Osceola National Forest. In 2007, the Bugaboo fire burned 306,984 acres in Georgia and Florida and in 2012, the County Line Fire added insult to injury. This specific section of the national forest is newly acquired land that was formerly private industry timber lands used for pine plantations.

The project is planting longleaf pine, creating potential habitat for the threatened gopher tortoise. The tortoise’s population has greatly decreased due to habitat loss and humans using it for food.

And in Florida, American Forests is planting 30,000 longleaf pine trees near the St. Johns River as part of the Hal Scott Regional Preserve and Park Longleaf Planting.

The Arbor Advisor

by Loose Leaf Contributor

Each year, the International Society of Arborists (ISA) recognizes several arborists as “True Professionals of Arboriculture” for their unique contributions to the field. These arborists do not limit themselves to tree care, but also work to educate and reach out to the local community about the importance of urban forests.

As the New Year draws closer, Loose Leaf will dedicate each Monday in December to one of 2013’s five True Professionals in appreciation of their work and the work of arborists everywhere on behalf of our trees.

We’ll start by taking a look at the life and work of second-generation arborist Terrill Collier, a plant health care consultant for Collier Arbor Care, a division of Bartlett Tree Experts, in Portland, Ore.

Terrill Collier is an outdoors kind of guy. He started backpacking in high school and completed a three-day trip around Mt. Hood, the highest mountain in Oregon, by himself. Ever the adventurer, Collier went to Europe after college for two years, traveling to 14 Western European countries. “When I finally came back to the states and settled down in the family business,” Collier recalls, “I realized that I loved my career as an arborist and have been at it ever since.”

Collier Arbor Care of Portland, Ore., began with Terrill’s dad as head of sales driving the company truck and his mom as the bookkeeper who also handled the phone. Today, Collier’s wife, Janet, is his business partner, co-owner and office manager. Their son, Logan, is a third generation ISA Certified Arborist and competition tree climber, joining 26 employees who have made this small business one of the premier arboriculture firms in the Beaver State.

“I grew up exposed to the business of arboriculture and learned to help out,” says Collier. “One of my father’s favorite sayings was work smarter, not harder. When I took over as manager of the business in 1980, he said to get ahead and be the most professional company we could be, we needed to belong to an organization like ISA. We became founding members of the ISA Pacific Northwest Chapter.”

Collier advances the arboriculture profession by promoting best practices. He publishes, “The Arbor Advisor,” a client newsletter with advice on proper tree care. He is also a leader in sustainable landscape practices and wants his company to be on the leading edge in the green industry.

“Many other industries claim to be green, but I believe that arborists are the original ‘greenies,’” maintains Collier. “I subscribe to the philosophy of running our company by the new triple bottom line: people, planet and profit. You need to take care of your people and the community, protect the planet and show a profit year after year in order to be sustainable.”

For the past five years, Collier has been working on the sustainability initiative for his business which also includes: an organic nutrition program for trees and shrubs, solar electric at the Collier office, a bio-wash pad for cleaning the company fleet of trucks and recycling office and industrial waste.

Collier’s peers say his arboriculture footprint reaches far and wide as past president of the Pacific Northwest Chapter of ISA, promoting the Trees Are Good website, encouraging ISA certification among his employees and running one of the most civic-minded tree care companies in his region.

“I have been a volunteer for various committees and Boards in our industry for the past 30 years. When I volunteer, I get back more than the time I have put in. Working with leaders in arboriculture helps advance my skill and knowledge. I encourage young arborists to step forward. It will pay back to you many fold.”—ISA and Terrill Collier

Come back next Monday as we celebrate an arborist who’s inspiring the next generation.

Season’s Eatings

by American Forests

By Marcelene Sutter

Traditional Thanksgiving turkey dinner

Have you ever wondered where the tradition of Thanksgiving turkey came from? Perhaps we owe this delicious custom to the way that we used to eat — seasonally. Before buying locally and eating seasonally became trendy, they were simply a way of life. It makes sense: Greens were popular in the spring, when they began to sprout, and summer vegetables, like corn and tomatoes, were enjoyed in the heat. Turkeys and chickens born in the spring would reach optimal roasting size by autumn, making them ideal for fall feasts.

This era of eating locally was not, relatively speaking, very long ago, but now that we have the ability to transport out-of-season produce to stores on a consistent basis, it’s not difficult to find tomatoes or asparagus on the shelf of your local supermarket in the dead of winter. Convenience aside, is the ability to eat out of season worth it? From an economic, environmental and taste standpoint, the answer might be no.

The transportation of out-of-season produce not only costs more compared to local produce because of the increased distance from field to table, but also has a much more pronounced environmental impact. When the use of aircraft or a longer journey by truck is required to transport these fruits and vegetables, more fossil fuels are consumed and more emissions released into the atmosphere, contributing to pollution. Increased air pollution can result in acid rain, which contributes significantly to forest soil degradation and can injure or even kill trees. Furthermore, foods that have longer distances to travel are harvested before they fully ripen, which means that the consumer loses out on maximum flavor potential, and is buying a more expensive and harder to digest product.

There are a few simple things that you can do to lessen the environmental impact of your holiday meals. By shopping at farmers markets or buying as locally as possible, you can limit the environmental effects associated with getting food from the earth to the dinner table. Planning dinners while staying conscious of what produce is in season will help you to create tastier dishes that help preserve the environment and support community businesses. No matter what you cook for Thanksgiving dinner, we at American Forests wish you a happy holiday season!

President Kennedy and the National Forests

by Alison Share, Environmental Public Policy Associate, Crowell & Moring LLP

This month marks the 50th anniversary of the assassination of President John F. Kennedy in Dallas, Texas. Much of the coverage and retrospective articles you have no doubt seen cover the events of that Friday, November 22, 1963. Others focus on the Cuban missile crisis and his interactions with the former Soviet Union. But for all of the reflections on President Kennedy’s policies in the realm of foreign policy and civil rights, it is what he did for our national forests that is the topic of this retrospective.

The National Archives contains a record of all the Executive Orders (EO) issued since the Hoover Administration, although currently you can only view specific EOs dating back to 1937 online. But all of President Kennedy’s are listed there, which is where we find his legacy relating to national forests (NF).

Not quite four months after his inauguration, in April of 1961, President Kennedy issued the first of his seven EOs concerning national forests. The first one modified the boundaries of nine forests in Illinois, Michigan, Missouri and Wisconsin, excluding lands that had previously been in private ownership. The second and third ones were issued on the same day, February 9, 1962, in the second year of his presidency. Both EOs altered existing national forests. The second redefined the boundaries of the Caribbean NF in Puerto Rico while the third actually consolidated two separate national forests in Michigan: the Hiawatha and the Marquette.

The Hiawatha NF, in the Upper Peninsula, currently consists of approximately 1 million acres, almost a quarter of which was part of the former Marquette NF. Three months later, in his fourth EO, President Kennedy added the additional land of Round Island to the Hiawatha NF. In addition to extending the acreage of the Hiawatha, the EO also transferred lands between the Mark Twain and the Clark National Forests in Missouri.

Twenty-six parcels of land within Tennessee and Virginia were allocated to the Cherokee and Jefferson National Forests by the fifth EO, issued November, 1962. The specific parcels of land designated by President Kennedy were identified in a prior agreement between the Tennessee Valley Authority and the Department of Agriculture (the agency that houses the U.S. Forest Service) as appropriate for national forest lands.

On the same day, November 29, 1962, the Federal Register published President Kennedy’s sixth EO, which emulated the parameters of the fifth one and formalized an agreement set out between the Tennessee Valley Authority and the U.S. Department of Agriculture. This time, lands near the Nantahala and the Cherokee National Forests, located in North Carolina and Tennessee, were included in and reserved as a part of the two national forests. President Kennedy’s seventh, and final, EO concerning the national forests was published in the Federal Register on January 1, 1963. This EO extended the boundaries of the previously designated Superior NF in Minnesota, and the Clark NF in Missouri. If you’ll remember, the Clark benefited from a land transfer from the Mark Twain NF in President Kennedy’s fourth EO.

Even though President Kennedy never designated new forestlands, he did enhance and add to the forests already in existence when he assumed office in 1961. Even without a new designation, and having less than one term in office, President Kennedy made his mark upon numerous national forests throughout the southeast and the Midwest. Ask not, indeed.

Putting Pheromones to Work

by Susan Laszewski

You might expect to find a blog post about how to use pheromones to their full potential on a dating blog, but we’re not talking about human pheromones. We’re talking about beetles.

At American Forests, we’ve been using a synthetic version of the pheromone verbenone to repel the destructive mountain pine beetle from whitebark pine. The verbenone patches mimic that which the beetles give off to communicate to other beetles that the tree is full. “No room — find your own tree,” the pheromones say. By arming healthy trees that are most likely to survive other threats with verbenone patches, we can help give the whitebark pine population a fighting chance against the mountain pine beetle.

But there’s another way that pheromones can be used to help forests under siege by these beetles. They don’t just repel — they also attract. Researchers from the University of Alberta are developing a bait to monitor the beetles’ activity in Canadian jack pine forests. By using pheromones to attract the beetles to “trap trees,” the beetle population can be concentrated to a limited number of trees. Then, those trees — and the beetles along with them — can be removed, sparing the surrounding trees from attack.

Studying the concentration of beetles on trap trees can also tell us more about their population in different areas. This could help managers make decisions about priority areas for containing what lead researcher Dr. Nadir Erbilgin calls “the most damaging insect in North America.”

Though baits of this kind have been used in lodgepole pine forests before, this study is investigating their use with jack pine — a tree that, until recently, was not believed to support the mountain pine beetle. But, as the beetle population explodes across the Western U.S., they’re increasingly attacking jack pine — and whitebark pine. Whitebark pine lives at elevations in which the beetles previously ventured rarely and died during winter. As winters warm up, the beetles are getting more and more comfortable — and living longer — at higher elevations. Their attack on the whitebark pine population is having cascading effects throughout ecosystems like the Greater Yellowstone Area.

The study on jack pine bait was published last month in New Phytologist and the researchers’ field trials in the jack pine forests will continue through the summer. In the meantime, you can help us with our work repelling the beetles from healthy whitebark pine trees by supporting our Endangered Western Forests initiative. Let’s arm our forests with the tools to fight off North America’s “most damaging insect.”

A Tree and a Recipe

Found from the Great Plains eastward and from Georgia to Massachusetts, the black walnut tree prefers rich floodplain soil and usually associates with other hardwoods such as maple, elm and sycamore.  Considered somewhat rare, its wood is used for furniture and gun stock. Some thieves have caught on to its value and have posed as arborists and made off with a tree! Growing a full, mature black walnut can take 60 years and a 200-year old tree can fetch tens of thousands of dollars. The story of how this wild crop goes from the forest to your table is told in the American Forests magazine article, “A Wild Crop and Backyard Harvest.” But how does the walnut’s story continue once it arrives in your kitchen?

Fortunately for black walnut lovers, harvest comes in October — right before Thanksgiving. You can substitute black walnuts in many foods that call for English walnuts. There are many recipes for black walnuts, including this simple one for black walnut pie:

The True Cost of Forest Fires

As the world warms up, the struggle to raise the money to fight increasingly intense and more frequent forest fires continues. The rise in temperatures is causing trees to dry out, and fire-prone areas are already feeling the effects. Wildfires are burning stronger and longer, and the government is struggling to provide the funds to fight back. These fires have become a nightmare both for the officials struggling to find the funds to fight them as well as for the firefighters who work tirelessly to fight blazes that are burning more intensely than before.

The increasing threat of forest fires is directly reflected in the capital needed to fight them; before 1999, there was not a need to spend more than $1 billion per year on fire suppression, but since 2000, the budget for such efforts has been forced to steadily rise due to demand, and has topped $1.5 billion multiple times since 2006. This is a double-edged sword for the Forest Service, which is forced into “fire borrowing,” — taking funds from other programs to combat the fires that are destroying millions of acres of forests while simultaneously consuming millions of dollars. While these fires do need to be fought, this appropriation of funds takes away from other vital operations, such as reforestation efforts and research into new firefighting strategies, which work to reverse the negative effects of these devastating fires.

A new solution is being sought by policy makers, and Secretary of Agriculture Tom Vilsack said at an event in Fort Collins, Colo., in July that “…lightning strikes that start forest fires are treated differently from a funding perspective than hurricanes and tornadoes and other natural disasters. We think there should be greater alignment.” Congress included increased funding to fight wildfires in the Continuing Appropriations Act that ended the shutdown, but the struggle is still not over. At American Forests, we recognize the paramount challenge that forest fires present to forest health.

In the 23 years since amendments to the Clean Air Act imposed regulations on emissions of nitrogen oxide from power plants, nitrogen deposits in nine Chesapeake Bay area watersheds have declined 34 percent, according to a new study from the University of Maryland Center for Environmental Science, published last month in Environmental Science and Technology. The study’s lead author, Dr. Keith N. Eshleman, tells the Baltimore Sun that the reduced air pollution’s effect on the water was a surprise to the researchers. “Here the Clean Air Act has caused something to happen that’s wonderful and good news and completely unanticipated,” he says.

American Forests has been working toward the health of the Chesapeake Bay area through our Global ReLeaf program — establishing forested buffers along the banks of the James River and working with Delmarva Poultry to create buffer zones that would protect the Bay from the poultry industry’s pollution — so this is good news indeed. Here’s to continuing improved health for this important watershed.

Zion National Park in southwestern Utah is celebrating its 105th anniversary tomorrow, and there is a lot to celebrate! With deep, sandstone canyons, pinyon-juniper and conifer woodlands, hanging gardens and waterfalls, the park is a delight to visitors. Some 207 types of birds can be found in the park. This rich tapestry of habitats and species make it one of the most visited sites in Utah.

The park includes Horse Ranch Mountain, at 8,726 feet and desert, riparian and woodland communities and neighbors the Mojave Desert, the Great Basin and the Rocky Mountains. One of the more unique features within Zion National Park’s 229 square miles is a series of narrow sandstone canyons.

More than 1,000 species of plants can be found in the park, from tall cottonwoods growing along the river to towering pines and firs shading the higher elevations. Some plants in the park, such as prickly pears, cholla and yucca are adapted to the desert climate. In the hanging gardens, one can find colorful Zion shooting-stars, scarlet monkey flowers, and Western and golden columbines.

A variety of wildlife find food, shelter and nesting places in Zion. From the Endangered Species list, California condors fly above the cliffs of the park. Zion’s canyons are also home to the highest density of the threatened Mexican spotted owl — a species whose habitat American Forest has been restoring in New Mexico through our Trigo Reforestation Global ReLeaf project. But that’s not all. The park is home to approximately 67 species of mammals, 29 species of reptiles, seven species of amphibians, and nine species of fish. For all their sakes, we wish Zion National Park a very happy birthday.

Trout in Trouble

by American Forests

By Marcelene Sutter

Fishing is a fond memory for many of us, whether you spent childhood summers fishing with friends, or enjoy bonding with your children or grandchildren on fishing trips. Fishing for many in the American West means one thing: trout. The trout is iconic in this region, especially in Montana, where the cutthroat trout is the official state fish. The trout, native to the American West and prized by fisherman for its mild, earthy taste and by state governments for the income it generates (about $250 million per year in Montana alone), finds itself seriously threatened by climate change.

Climate change has not only warmed the water in the streams where the trout lives, but also caused droughts and reduced snow in the winter, negatively affecting water flow in the spring, making it harder for trout to move. In order to better understand the specific effects that climate change is having on trout in the west, scientists are using electric currents to catch and, subsequently, track the cutthroat trout, native to the northern Rockies region of Montana, with small transmitters known as pit tags. Brad Shepard of the Wildlife Conservation Society explains that the electric current is used as an attraction device to make the fish easier to net, telling NPR that the current “actually draws fish.” Scientists catch the fish, insert the trackers and release the trout back into the streams, beginning a years-long tracking process. Finding these trackers sometimes takes scientists off the beaten track; they have been found anywhere from marten dens to the freezers of local fishermen. Scientists are looking to follow the lives of these fish, determining growth and mortality rates, as well as time and cause of death. This data is collected and analyzed to determine any correlation to changes in stream flow and water temperature, to see if these factors affect the trout in a significant way. These factors really affect the trout, cueing “when they spawn, when they hatch, when they emerge, when they come out, how fast they grow, where they go,” as Shepard tells NPR. “But as you shift things in one direction, you can, in fact, lose part of the population.”

It will take time to fully understand the effects that lessened stream flow and higher water temperature have on cutthroat trout, but early emerging trends suggest that non-native fish, such as the rainbow trout, are moving further upstream, which previously was too cold for that species, into the cutthroat trout’s range. As the two trout species mix, rapid hybridization occurs, resulting in a marked decrease in trout fitness. This new, weaker trout becomes prey for fish, such as bass, which are moving into trout habitat that was once too cold for them. Climate change poses and new and serious threat to this iconic fish of the American West, and measures must be taken now, at the first sign of trouble to ensure its survival.
