How tall do blue spruces grow? Ornamental yard trees often reach 60 to 80 feet and 1.5 to three feet in diameter. Ostensibly reliable internet sources vary greatly on listed maximum heights. Some say more than 100 feet. Others cap the species off at 80, while one source lists 50 meters, or 164 feet. There’s little agreement, but the species pays no attention to such nonsense. Blue spruces know what they’re genetically programmed to do, and in southwestern Colorado, the blues achieve their best growth. The Western Native Tree Society (WNTS), supporting the American Forests National Big Tree program, discovered a blue to break all records in the La Plata Mountains this August.

Near Hermosa Creek, the team of Will Blozan, Matt Markworth, Larry Tucei, Chris Morris and Mark Rowe measured a huge blue at 165.5 feet tall, 12.5 feet in girth and 32.5 feet average crown spread. It was eagle-eye Will’s discovery and totals 324 points via the American Forests champion tree formula. The current national champion in Utah totals 331 points, making the Colorado tree a contender for co-champion under the large-tree rule — that a tree that measures within five percent of the champion’s points is eligible to become co-champion. The intrepid team also measured another blue at 164 feet tall and 10.1 feet around. But that was hardly the end of the discoveries.

Later, going solo, Matt confirmed a 155-foot blue with a 12.9-foot girth and 33.5-foot crown spread, earning the specimen 319 points and making it eligible for co-champion. Then it happened: Matt measured a pencil-straight giant at an astounding 178.8 feet, the tallest we know of — anywhere. The tree measures 10.9 feet in circumference. Its narrow crown averages only 23.5 feet for a total of 309 points. It may not be eligible for co-champion this year, but it’s height has blown records out of the water. It seems to be part of a trend; Matt measured other blues between 162 and 158 feet high. The number of blues measuring more than 150 feet is growing.

Champion trees show us the full potential of their species and these Colorado blue spruces are a prime example of that. In October, the world will find out whether any of the trees had their co-champion status confirmed and made it onto the National Register of Big Trees. But, whether they end up wearing that crown, they have shown us not to underestimate the blue spruce.

Note that these trees were all measured with LTI TruPulses (200s and 360s) using the sine method, accurate to +/- 0.5 feet. (See the American Forests webinar on measuring tree height.)

Introducing tree-pest expert Faith Campbell

Faith Campbell knows a thing or two about trees and the insects that threaten them. She brings years of experience, including her most recent post at The Nature Conservancy, to Loose Leaf as one of our new guest bloggers.

Before diving into the interesting and sometimes volatile relationship between trees, insects and humans, we wanted to learn more about Faith herself:

What led you to the forestry field, and tree pests in particular?
I have always loved trees and natural areas. In the 1950s, when I was growing up in northern Virginia, the streets and parks of Washington, D.C., still looked like cathedrals because of the interlocking branches of elm trees. I learned about Dutch elm disease, and then that additional non-native pests were killing chestnuts, hemlocks. I wanted to do something to reduce this threat.

What are some tree-versus-pests successes you’ve observed in your career?
The biggest success has been with the Asian longhorned beetle (ALB) — although that story is not yet over. Determined efforts by federal, state and local agencies, private citizens working individually, and organizations and funding associations, have succeeded in eradicating several outbreaks and they are making progress on other outbreaks. Also, the detection of several ALB outbreaks persuaded U.S. and Canadian policymakers that wood packaging (crates, pallets, etc.) is a high-risk pathway, so they led global efforts to require treatment of wood packaging. As I said earlier, this story has not reached its end — additional outbreaks of ALB continue to be found, and the treatments required for wood packaging have not yet eliminated the risk from that pathway. More remains to be done. But this situation points the way we should go and the level of effort needed.

Have there been any infestations that have threatened a particular tree species to the brink of endangerment or extinction? If not, are there any suggestions that this could happen in our lifetimes?
While none has yet driven a species quite to the brink of biological extinction, many of the non-native pests have caused the host species to decline to the point that it can no longer perform its role in the ecosystem. American chestnut has been reduced almost everywhere to short-lived root sprouts that cannot provide the huge crops of nuts that formerly sustained wildlife ranging from black bears to squirrels. Port-Orford cedar, several of the western white pines, and eastern hemlocks have been severely reduced over large portions of their ranges. The greatest threats currently are to the high-elevation, five-needle pines of the mountain west and to redbay in coastal regions of the southeast. The U.S. Forest Service Forest Health Technology Enterprise Team projects that redbay will lose 90 percent of its basal area throughout its range by 2027 — just 25 years after the insect-fungus combination was detected.

Is there a pest in particular whose effects on forests worry you?
Dozens! I will name two that pose severe threats, but to which state and federal plant health agencies have failed to respond: the goldspotted oak borer (GSOB) and polyphagous shot hole borer (PSHB). The GSOB has killed more than 80,000 trees in San Diego and Riverside counties in California over perhaps just 20 years. It threatens coast live oak, black oak and canyon live oak throughout the state, and north into southern Oregon. The PSHB is already established across most of the Los Angeles basin, with a separate outbreak in San Diego County. PSHB is known to attack close to 300 different tree species, including nearly all the trees that grow in riparian areas in southern California. The fungus that it transports is known to live in more than 100 species. Trees considered reproductive hosts for the beetle include five types of maple trees, five oak species, two sycamore or plane trees, and several species common in the nursery trade such as camellia. Some of the hosts, such as box elder, are widespread in the eastern U.S. as well as in California. Yet the California Department of Food and Agriculture and USDA Animal and Plant Health Inspection Service have not developed programs aimed at preventing the spread of these insects.

Where do you see the relationship between trees and invasive insects in the next decade? What can we — NGOs, government agencies, corporations and U.S. citizens — do to help ensure the healthy and vitality of our country’s forests?
Over the next decade, non-native insects and pathogens will continue to enter the United States; and the nearly 500 species already here will continue to spread. Additional tree species will face threats from new invaders, and trees formerly protected by distance from pest outbreaks will be put at risk by the established organisms’ spread. To reduce the devastation to the greatest extent practicable, government agencies, corporations, citizens and organizations can adopt practices that minimize the presence of pests in items that they move from one place to another. High-risk articles include wood in many forms: firewood, logs or burls used in woodworking, decorative items or rustic furniture; crates, pallets, spools for cable; as well as plants for our gardens. In future blog posts, I will discuss the specifics of what government agencies, corporations and citizens can do.

A presidential plea

by Christopher Horn

Last week, American Forests launched its first-ever petition through TakePart’s Take Action forum — a letter to President Obama to make forests play an important role in the country’s climate change plan — and have seen a tremendous amount of people from across the world sign on.

Forests across the country and world are succumbing to a range of threats, from drought and wildfire to pests and diseases, all of which are exacerbated by climate change.

Forests across the country and world are succumbing to a range of threats, from drought and wildfire to pests and diseases, all of which are exacerbated by climate change.

President Obama announced the initiative in July, highlighting rising temperatures, carbon pollution, and the country’s preparedness for the impacts of climate change.

Forests and climate change have a dynamic relationship. Trees absorb carbon dioxide, one of the biggest contributors to climate change, and convert it into clean oxygen, which they release, and carbon, which they store. Sound forest management practices and increased funding can help these important natural resources maintain and improve their potential to sequester carbon, maximizing their ability to mitigate climate change.

Please take a moment to sign the petition and share with your friends and family on Facebook and Twitter. With your support, we can encourage the president and his staff to ensure that forests have a place in our country’s — and world’s — climate change conversation.

The first Forest Digest of August features some major wildfire stories.

Check out this week’s news in trees:

  • “Swedish Forest Fire Prevented From Spreading”The Wall Street Journal
    Made worse by high temperatures and dry conditions, one of the most devastating wildfires in Sweden’s recent memory burned in a region 140 kilometers northwest of Stockholm, the capital. One person died and thousands were evacuated.
  • “Singapore to fine domestic, foreign companies for causing haze”
    Racked by air pollution caused by peat and forest fires in Sumatra, Singapore’s parliament voted to fine domestic and foreign companies who participate in forest burning that creates smoggy and hazy conditions, which experts say may be worse this year because of hotter, dryer weather.

Smokey at 70

by American Forests

By Carrie Brooks, Communications Intern

This Saturday, Smokey Bear will take a short break from helping prevent forest fires and turn his attention to the flames atop 70 candles. Fortunately, there is no disaster here: these lit candles will adorn the American icon’s birthday cake!

Smokey was brought into being by the U.S. Forest Service and the Ad Council as a vehicle to educate Americans on preventing forest fires. The bear has withstood the test of time. His simple-but-powerful slogan is familiar to most every generation: “Only you can prevent wildfires.”

However, Smokey Bear is not only an icon — he is an advocate. His message of wildfire prevention is still relevant; humans cause 90 percent of wildfires. The National Interagency Fire Center reports that humans in the United States are responsible for an annual average of 62,631 fires that burn more than 2.5 million acres every year.

Human-caused wildfires are destructive, yet, this negative stereotype is not always accurate. In many circumstances, fire benefits forests.

Jami Westerhold poses with Smokey Bear at a volunteer event in summer 2014.

Jami Westerhold, Senior Director of Forest Restoration Programs, met Smokey Bear at an American Forests volunteer event in the Greater Yellowstone Area this summer.

Jami Westerhold, American Forests’ Senior Director of Forest Restoration, says low-intensity wildfires create openings, increasing sun exposure and water supply, which encourages plant growth and regeneration. Fires leave ash that can serve as a fertilizer and also help protect trees in the vicinity from certain threats.

“Fire can also help eliminate pests and diseases that damage forests and creates diversity in plant ages — or successional stages,” she said. “This develops a healthier forest ecosystem and benefits wildlife.”

However, high-intensity fires are not among these circumstances. Jami notes that, in these situations, “seed sources and soil nutrients are severely impacted, preventing natural regeneration.” This is where American Forests’ involvement begins.

While Smokey Bear works to prevent wildfires, American Forests is dedicated to reforesting areas affected by high-impact wildfires. With the cooperation of our partners in the field, the organization endeavors to reforest the grounds with native trees.

Reforestation in these areas revitalizes ecosystems and improves forest and fire management. In turn, these actions limit damage from and can prevent altogether future fires — something that would please Smokey Bear!

Our Hill adventure

by Christopher Horn

By Caroline Brooks, Communications Intern and Sofia Maia-Goldstein, Policy Intern

Last week, our policy intern Sofia discussed the fifth anniversary celebration of America’s Longleaf Restoration Initiative (ALRI). Because American Forests is one of ALRI’s partners, she had the opportunity to attend several events both at the Department of Agriculture offices and on Capitol Hill.

Caroline, our communications intern, joined Sofia for one Hill activity. The two interns accompanied several South Carolina longleaf pine advocates for a meeting in the office of one of their senators, Lindsey Graham.

The meeting was a unique experience for both Sofia and Caroline. Continue reading to learn more about this gathering from the interns’ perspectives.

Caroline, left, and Sofia joined constituents from South Carolina to advocate for the restoration of the state’s — and region’s — longleaf pine forests.

Main Point 1: Federal and State longleaf reforestation programs in South Carolina have proved highly beneficial.

CB: John Spearman, a private landowner who participated in the meeting, spoke highly of several federal initiatives that have allowed him to successfully grow and maintain longleaf pine. John has run a successful tree farm for many years.

Several years ago, a hurricane uprooted and destroyed vast longleaf population. Fortunately, he had enrolled his farm in a U.S. Forest Service (USFS) program years prior. The support of this federal project, allowed John to reforest his land with longleaf pines that continue to thrive today.

SMG: April Donnelly, director of government relations for The Nature Conservancy in South Carolina, explained the importance of these longleaf restoration programs for low-income South Carolinians. Families unable to manage their own land and resources can seek support through USFS and local programs. By planting longleaf pine, constituents ultimately regain the historical integrity and economic benefit of their land.

American Forests has played a key role in South Carolina’s longleaf restoration through critical reforestation programs that have re-introduced more 5 million trees to the area.

Main Point 2: This meeting also impressed us with the legislative process and its role in longleaf restoration.

CB: What struck me the most about the meeting was the incredible first-hand way we were able to witness the average American citizen actively engaged in democracy. These individuals from various backgrounds were able to come together around a common concern to petition their elected officials.

SMG: J.P. Tyson and Scott Graber, the two legislative aides present, emphasized the Senator’s past support of longleaf restoration through the farm bill and showed an understanding of longleaf’s importance for both his constituents and the state of South Carolina.

This experience showed us the significance of both the legislative process and the relationship between constituents and policymakers. The future of the longleaf depends heavily on federal support, which can continue to be made possible largely by the dedication and advocacy of individuals and organizations. Such initiatives have been successful in the past because constituents — like those with whom we interacted — have given a voice to the issue.

An update on the longleaf

by American Forests

By Sofia Maia-Goldstein, Policy Intern

America’s Longleaf Restoration Initiative (ALRI), a group of private and public partners that seeks to restore and conserve longleaf pine ecosystems in the southeast U.S., made strides in the political world last week.

Addressing the loss of 90 million acres of longleaf forests from its original range, American Forests and a diverse number of stakeholders, including conservation and forestry groups, private landowners, and multiple state and federal agencies, have come together to work towards restoring millions of acres of longleaf forest.

In the past five years, 1.38 million acres of newly planted trees have helped reverse the decline of the species, which ranges from Virginia to Texas. In celebration of progress, the initiative held a panel, featuring Secretary of Agriculture Tom Vilsack, who moderated a small group of landowners, a state forester, industry and Longleaf Partnership Council members to discuss the success to date as well as how to sustain efforts in years 6-10. Following the panel, a reception was hosted by Natural Resources Conservation Service Chief Jason Weller and U.S. Forest Service Chief Tom Tidwell.

In addition to celebration, constituents and conservation organizations visited Congress to address necessary funding for reforestation programs to ensure the reestablishment of longleaf continues on an upwards trend.

Although the Farm Bill provides mandatory funding for many of these programs, the FY15 Agriculture Appropriations bill currently proposes a reduction to a number of programs, including the Environmental Incentives Program, the Conservation Stewardship Program and the regional Conservation Partnership Program. When discussing FY15 with congressional staffers, the ALRI advocated for the FY12 levels for these programs, as funding has decreased from that appropriated level since.

Addressing wildland fire and budgeting problems in the Departments of Agriculture and the Interior will also be critical in maintaining longleaf pine forests and ensuring money from associated programs is not shorted because of a “borrowing effect” from a lack of funds for fire suppression. Proper funding for these programs would mean quicker and more efficient restoration along with a number of economic, environmental and social benefits for communities involved.

These precious forests support a large amount of wildlife species, offer high quality timber opportunities, provide a buffer zone for military installations, and restore historical integrity to the land. American Forests has recognized the critical importance of these pines by taking action on the ground. Through several programs, we have helped plant more than five million longleaf pines since 1992. These new habitats continue to offer a home for endangered species including the gopher tortoise and the red cockaded woodpecker.

Together with support from several regional and federal agencies, constituents and landowners, American Forests will continue to advocate for the reforestation of longleaf pine and the benefits the species brings to the southeastern U.S.
