From Oil to Trees

by American Forests

By Michelle Werts

Arboriculture was not his first career for this week’s International Society of Arboriculture’s 2012 True Professional of Arboriculture. Texas-based Bruce Kreitler actually toiled on and around oil fields for 25 years before the demands of the job led him to turn his passion for trees into a new career.

“I spent 25 years working in oil fields — 15 years in the Middle East,” recalls Kreitler. Oil field supervisory jobs were lucrative, plentiful and challenging, but in the end, it was Kreitler’s rig schedule of 35 days on the job and 35 days off that opened up the possibility for this arborist. There was simply so much time to read and study.

“I’ve had a lifelong interest in trees and have always dabbled in trees,” replies Kreitler. “The time off allowed me to do some pretty intensive study on trees, not just work on them. I finally built up a tree business to the point where I had to decide which one was going to be my regular job.”

Kreitler incorporated his business, Broken Willow Tree Service, in 1999 and hasn’t looked back. Now, he uses several platforms for public outreach to educate people about proper tree care. He hosts free workshops, writes more than a dozen articles a month for five area newspapers, contributes to two online publications and hosts a weekly radio show, “West Texas Trees and Landscapes,” on KWKC 1340 AM in Abilene.

“The writing, the radio show and the public speaking — it gets people involved,” explains Kreitler. “It doesn’t do me any good to know everything I can about trees, nor would it matter how many people worked for me, if I wasn’t successful at public outreach. The True Professional is someone who is getting out there and working for the public, feeding the right information to them.”

Beyond his public outreach and daily tree-care work, Kreitler, who is an ISA-certified arborist, ISA noard-certified master arborist and a municipal and utility specialist, is guiding a special project initiative as a member of the Buffalo Gap Tree Board. Buffalo Gap is an area in Texas known for a unique, old live oak forest that was left in place by the original settlers.

“This area of historic trees is a shady forest spot in the middle of the sun-blasted plain,” Kreitler declares. “Buffalo Gap is one of the original settlements so the people who first lived there are the ones who purposefully left these trees in place. There’s a lot invested here. The tree population is in decline, so I am helping the board with a planning program. I encourage them to plant more burr oaks, among other species, to diversify the forest. The people that settled there gave us a present by not cutting down those trees. If we go in there and plant other trees, it will be a gift for future generations.” –ISA and Bruce Kreitler

Come back next Friday to meet a poet and writer who helps protect historic trees in New York.

A Hospital Oasis Under Threat

by American Forests

By Michelle Werts

Sometimes — oftentimes — it feels as though nature and development are locked in an eternal battle. Cities and communities are continually running out of space, while trees, flowers and shrubs need lots of precious space to thrive. So what is one to do when more space is needed for infrastructure, but the only way to get it is to destroy a greenspace? That’s the question currently facing Boston Children’s Hospital.

Boston Children’s Hospital is one of the largest pediatric medical centers in the U.S. and services almost 25,000 inpatient admissions each year. It has more than 1,100 scientists producing research and is one of the best pediatric hospitals in the country according to U.S. News & World Report. It also has “one of the most successful hospital gardens in the country,” as Clare Cooper Marcus, an emeritus professor in landscape architecture at the University of California, Berkeley, tells Scientific American.

Tucked between the Wolbach and Farley buildings on the hospital’s campus is the green oasis known as the Prouty Memorial Garden. The garden is the brainchild of Olive Prouty, who set up an endowment for the creation and maintenance of the garden back in the 1950s. The famed Olmsted Brothers architecture firm designed the restful place — modeling it on the terrace and garden at the Museum of Modern Art in New York City — and it’s become a treasured part of the hospital. But that may soon change.

A column in The Boston Globe earlier this month details that the location-strapped hospital is currently exploring ways to increase its space, and one idea on the table is building new facilities where Prouty Garden currently offers respite for patients, visitors and staff. Margaret Coughlin, a Children’s Hospital senior vice president in charge of marketing and communications, tells the Globe that “as we look at what we have to do to be a clinical and innovative leader, we have to look at all our space, and there is no new space in this area.”

On the flip side are the patients and parents who have viewed the garden as a sanctuary over the years. A petition has been started to try to help preserve the garden. Signatory Jennifer Lubao writes that “The garden was such a place of peace for me the four months I stayed with my infant son at the hospital. The chapel was the only other place where I felt such peace. Both gave me the strength to deal with the chaos surrounding my infant son’s extended illness and death. I can’t imagine a proposal to tear down the chapel so why the garden where so many of us pray and meet one another as a community?”

The Globe reports that any action regarding Prouty Memorial Garden is a few years down the road. Let’s hope that the famed hospital is able to figure out a way to preserve such a vital, recuperative space, while also advancing its other work. We need new research to battle disease, but as research tells us, we also need green oases to fight and recovery from those diseases.

Hurricanes and Habitats

by Amanda Tai

This week, Hurricane Isaac threatens to hit the same area that was hit by Hurricane Katrina seven years ago. Ever since I experienced a flood firsthand, I have been in awe of storms and how extreme weather can have an impact on people and places. The memory I have of being evacuated from my home gives me a clearer understanding of storms like Hurricane Katrina and how traumatic it must have been for the people of New Orleans. So when I heard that another hurricane was heading towards the Gulf Coast, it reminded me of the devastating impact storms can have.

While most media attention focuses on people and developed areas, storms also have an impact on wildlife habitat. I decided to look into what happens after a storm has hit, specifically in regards to wildlife habitat restoration and reforestation. According to the U.S. Forest Service, Hurricane Katrina caused damage to five million acres of land, which included coastal forests that many migratory bird species and other wildlife species called home. According to a 2007 study, more than 320 million trees were killed. Further inland from the coast, 50 to 80 percent of Mississippi’s trees were damaged. This has a great impact on wildlife food and shelter. While it’s easy to see that heavy rain and strong winds knock trees over, they also strip vital food sources like seeds and berries from trees.

But damage isn’t just limited to dry forests. Storms like Katrina also have a high impact on wetland habitat by increasing water levels and changing the salinity of the water. James Harris, a biologist at the Breton National Wildlife Refuge, told the National Wildlife Federation that the rainfall from Hurricane Katrina forced salt water into freshwater marshes, which eventually killed trees and severely reduced waterfowl food sources, like fish.

Another concern for wildlife managers is the likelihood of a species leaving the area and not returning once the storm is over. Tommy Michot, a biologist with the U.S. Geological Survey who conducts aerial canvases of Louisiana birds, noted the decline of 10 coastal bird species after Hurricane’s Katrina and Rita. Since storms greatly disturb wildlife habitat, it’s important that these areas are restored afterwards. It certainly is reassuring to know that there are several programs in place like the Hurricane Wildlife Relief Fund, the Emergency Watershed Protection program and American Forests Global ReLeaf to help restore our wetlands and coastal forests.

Fire in the West – Part 2

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

This month is part two of the brief overview of the history of the U.S. Forest Service’s fire policy. In the past few weeks, Loose Leaf posts have covered the recent, temporary halt to the “let it burn” policy in light of the tinderbox quality of the West, partially due to the current drought conditions. As you’ll remember, the “let it burn” policy evolved in the 1970s to counteract years of total fire suppression. Rome wasn’t built in a day, however; years of fire fuel — accumulated on forest floors — are making this summer’s fires particularly ferocious. But what’s that about the Healthy Forests Initiative and the very exciting regulatory actions I promised last month? I’m glad you asked.

As briefly mentioned before, the National Environmental Policy Act (NEPA) requires that an agency undertake either an environmental assessment (EA) or the more-involved environmental impact statement (EIS) for any major federal action that may significantly affect the environment. An EA is the basic evaluation of the potential environmental impacts of a federal action, and it leads to one of two results: a Finding of No Significant Impact (yes, a FONSI) or a determination that an EIS is needed — sometimes agencies forgo the EA and jump straight to an EIS. An EIS, as it stands to reason, is a much deeper look at a project’s environmental impact. If, however, an agency has created a categorical exclusion for a particular action, which saves time and money in getting a project off the ground, than neither an EA nor an EIS is needed.

The Healthy Forests Initiative, in conjunction with the Healthy Forests Restoration Act (HFRA), developed categorical exclusions for certain projects intended to reduce forest undergrowth that feeds fires, as well as activities to repair or rehabilitate lands damaged by fire. HFRA is not without its detractors. With no requirements for environmental review in specific instances, concern was raised that old-growth trees would be removed in the name of clearing out forests to lessen fuel available for large conflagrations. On the other side, because HFRA actions are only allowed on land under the control of the Bureau of Land Management and the Forest Service, the ultimate utility of HFRA is limited.

HFRA also includes provisions that accelerate NEPA review of hazardous-fuel-reduction projects near Wildland-Urban Interfaces (WUIs). As many environmental attorneys will tell you, the NEPA process can take a significant amount of time to complete, arousing either the ire or relief of the affected parties. WUIs are those areas of land that have homes either abutting or incorporated within lands that are particularly prone to fire. By accelerating the NEPA review for fuel-reduction projects in those areas, HFRA placed additional significance upon protecting the homes and communities interspersed among areas most susceptible to fire. In addition, NEPA review is also accelerated for ecosystems currently suffering, or at imminent risk, from a disease or insect epidemic.

Perhaps reflected by the ever-expanding set of acronyms, fire management is an ongoing concern. Resource management plans coordinating the use and managing of lands and forests are written and rewritten for different areas. Congress continues to pass additional legislation to help deal with the ever-changing threats from fire, such as the Federal Land Assistance, Management and Enhancement Act of 2009 (the FLAME Act), providing much needed funding for fighting wildfires. And groups such as American Forests continue the never-ending task of educating the public about the contributing factors of fire. While Smokey Bear was right that “only you can prevent forest fires,” it is a nonstop effort by the Forest Service to temper their strength, size and ultimate impact.

A Lesson From the Past

by American Forests

By Michelle Werts

The Americas have been home to many storied cultures, like the Incans of modern-day Peru and the Aztecs of modern-day Mexico. But pre-dating both of these were the Mayans, who ruled Mesoamerica — the region from central Mexico to Central America — for centuries and centuries and who are renowned for their art and architecture, astronomy, mathematics and more. Archeologists have traced the Mayan culture back to 1,800 B.C., but the civilization’s glory period would only be from 250-900 A.D. — when all of sudden the culture’s reign ended. Unlike the demise of the Incans and Aztecs that can be attributed to European conquerors, archeologists only have theories about what happened to the Mayans. In recent years, though, more and more researchers are theorizing that the climate, specifically in the form of a series of droughts, may have played a big part in this great culture’s demise — and that the Mayans themselves may have contributed to the climate change that would be their undoing.

In a new paper in Geophysical Research Letters, researchers posit that deforestation for agricultural purposes during the Mayan reign contributed to increased drought levels, which may have been a major factor in the civilization’s decline. Based on their research, the paper’s authors estimate that precipitation during this period decreased by five to 15 percent compared to what rainfall would have been with natural forest cover. Their models also suggest that up to 60 percent of this decline in rainfall is attributable to deforestation.

How does deforestation for agriculture increase drought? Dark, dense vegetation — like Central America’s rainforests — absorb lots of light and energy from the sun, which aids transpiration (the evaporation of water from plants and trees). Sunlight helps the pores on leaves, called stomata, open, allowing more water to evaporate. Many crop plants, like corn, absorb less light and energy, reflecting more of it back into the atmosphere and decreasing conditions favorable for rain. So, as the Mayans cut down forest to make room for their burgeoning population of more than 19 million people — and to grow food to feed those 19 million people and build magnificent, lime-plaster-based cities — a drought-prone region of the world became even drier.

The tale of the Mayans holds much resonance today: a prosperous, technology-advanced society, struggling to keep up alters its environment to help solve its problems. Except, as it turns out, altering that environment may have actually caused more problems. So maybe we should all take the Mayans as a sober, cautioning tale — and remember to look to our forests as helps rather than hindrances.

For the Love of Trees

by American Forests

By Michelle Werts

Earlier this month, the International Society of Arborists (ISA) announced the five members of the 2012 class of its “True Professionals of Arboriculture.”

According to ISA President Colin Bashford, “The True Professional honor is a celebration of those who reach for and strive to maintain high standards of the arboriculture industry. Their achievements and ideas educate and inspire others. We are proud they play such a leading role in promoting quality tree care.”

Since arborists are on the frontlines every day, protecting and studying trees in our cities, communities and forests, Loose Leaf is taking the next five Fridays to recognize this year’s “True Professionals” in celebration of the work of thousands of dedicated arborists across the country and around the world.

First up is Tim Kastning, an Idaho-based, ISA-Certified arborist and owner of Grace Tree Service, Inc.

Tim Kastning did not always plan on being an arborist. In fact, he was studying theology at Baptist Bible College in Springfield, Mo., when his “true calling” struck. He was 25 years old and doing lawn-care work as the owner of American Lawn and Garden in Springfield. While driving down a street one day, he spotted a worker aloft in a tree on a rope and saddle.

“The man was tip-tying branches and roping them down over a house,” Kastning remembers. “I watched from my truck for about a half hour, and it was there I decided I wanted to do tree work. When this person came down from the tree, I introduced myself. Right then he taught me two knots — a taught-line hitch and a bowline. I memorized them and went home to practice them. I later bought some chainsaws, rope from a farm-and-feed store and climbing gear. I thought I was prepared. I remember the first tree I pruned was a large pin oak about 30 inches in diameter, and I killed it.”

Fortunately, the death of that tree didn’t end his career. With no real formal education in arboriculture, Kastning took advantage of various industry programs and quietly got involved where he could. He became an ISA-certified arborist, a board-certified master arborist, certified tree risk assessor and certified tree care safety professional and maintains ISA certifications as a municipal arborist specialist.

Kastning looks to his community to grow as an arborist and to run a business with a clear focus on giving back. One day while at a Chamber of Commerce leadership meeting in Coeur d’Alene, he learned about ElderHelp and the firewood charity program.

“As a tree-care company, we don’t sell firewood, so I try to dispose of it however I can,” admits Kastning. “Between the United Way and ElderHelp, we formed a partnership to provide about 100 cord a year to the elderly who cannot afford to buy it. Community volunteers from churches and clubs come to our yard nearly every Saturday in the fall to split up the wood and deliver it. This wood comes from trees that have to be removed, so if we don’t sell it, it’s ground up and sent off. This is a better and higher use of it in the end.”

“I learned a lot about arboriculture on my own,” continues Kastning, “So the best advice I can give another arborist is to simply apply oneself to education and certifications, set up a business well and follow the laws. There are a lot of arborists that ‘do what we do.’ There are fewer arborists that know ‘why’ they do what they do. The more I know about arboriculture, the more I realize there’s always more to learn.” –ISA and Tim Kastning

Come back next Friday to meet an arborist who spent 25 years working in oil fields before making the switch to arboriculture.

Preparing for Wildfire

More than 6.3 million acres across the U.S. have burned in wildland fires this year so far — and dozens of fires are actively burning. Often, when we talk about wildfires, we focus on forest land-management practices, which then devolves into debates questions about fire suppression, prescribed burns and thinning and more. This can lead to policy questions and funding debates that happen far away from the burning fires. However, there are things that those most directly affected by the fires can do to help protect their homes and neighborhoods from the destruction that fire can wreak.

Smokey Bear famously proclaims that “you can prevent forest fires,” but this statement could be expanded to “and prevent the spread of forest fires.” Fires need fuel to burn — leaf debris, lawn trimmings and more all serve as food for a fire — which is why the U.S. Forest Service, National Fire Protection Association (NFPA) and Ad Council have instituted a new Fire Adapted Community campaign, designed to help homeowners, land managers, community leaders and fire and emergency responders institute pre-fire strategies that will help protect everyone if a wildfire strikes nearby.

What is a Fire Adapted Community? That’s pretty simple: It’s a community that acknowledges its fire risk and takes steps to diminish it.

Why is it important to become a Fire Adapted Community? Because more than 70,000 communities nationwide are near or within fire-prone ecosystems and are at risk of wildfire.

How does a community become Fire Adapted? That’s the best part: It’s not hard.

  • For individual homeowners, it’s simple things like keeping your roof and gutters clean and making sure you don’t leave your lawn clippings piled up.
  • For developers and business owners, it’s doing things like not building in high-fire-risk areas and using non-combustible building materials.
  • For neighborhoods, it means developing emergency response plans and helping homeowners keep their lawns debris free.

Wildfire knows no political, jurisdictional or other kind of boundary — pretty much just like everything related to the environment. Therefore, we must all work together to protect ourselves, our communities and our natural landscapes. To learn more about becoming Fire Adapted, visit

Protecting Our Parks

Federal agencies are bracing themselves for a funding crisis with budget sequestration cuts looming if Congress fails to create a plan to reduce the federal deficit. To boost funding and support, could online media be a part of the solution?

The Obama administration just announced a makeover to, the interagency website to get people to explore America’s public places. The new design provides users with a more interactive experience, where they can watch videos, plan trips and even make online reservations for their upcoming adventures. It comes as part of a multi-year effort to boost the economy through outdoor recreation and travel. Secretary of Agriculture Tom Vilsack hopes the new site will help boost the estimated $646 billion that tourism and recreation already contribute to the U.S. economy. While this figure is good news for the economy, the National Park Service is still struggling to operate on a tight budget.

The National Park Service makes up only one-fourteenth of one percent of the federal budget. Cuts of up to 10 percent could be made across-the-board if there is a budget sequestration — even though cutting 10 percent of one-fourteenth of one percent won’t make a dent in the deficit. Park managers are highly concerned about the effect that budget sequestration could have on jobs and the ability for parks to stay open and operating. Fixed operating costs that rely on federal funds represent a high portion of park budgets like for Fredericksburg and Spotsylvania National Military Park and Blue Ridge Parkway. These parks could really suffer if funding is cut by 10 percent. Thomas Kiernan, president of the National Parks and Conservation Association (NPCA), tells The Washington Post that federal funding is the number one threat to national parks, and this means that policymakers are going to have to face some tough decisions.

In a recent poll commissioned by the NPCA and the National Park Hospitality Association, voters said they want the government to ensure protection of our national parks through federal funding. Voters also expressed concern about funding shortages negatively affecting national parks’ visitor experiences. According to the poll, parks continue to receive bipartisan support, which hopefully carries over to Congress. You can urge Congress to reach a budget deal that ensures protection of our national parks by signing onto NPCA’s letter. It would be sad to see any of our national parks close, but if Congress doesn’t listen to what voters are saying, it may become a reality.

Urban Forests for Healthy Healing

Urban forests are vital to help maintain our emotional, mental and physical well-being.

The evening before I had wrist surgery a few weeks ago, I went for a jog. In a time when I was feeling anxious and just needed some time to think about the road of recovery ahead of me, I found myself jogging along a neighborhood trail within my local urban forest. I couldn’t help but notice that my surroundings immediately made me feel much better — more relaxed and encouraged to cope with the challenges ahead. That evening, I ran past the oaks, sycamores, sweetgums and elms of my community, leaving my worries behind me and feeling the peaceful strength and soothing encouragement that came from the green landscape around me.

I think most people would agree that seeing trees or being within nature can just make a person feel better — emotionally, mentally and physically. In fact, the National Park Service and Institute of the Golden Gate have recently been involved in promoting the health benefits of being outside through a program called “Park Prescriptions,” which helps connect healthcare and park resources.

The Park Prescriptions fact sheet provides several research examples of how exposure to nature has significant health benefits:

  • A Danish study published in 2007 concluded that adults who could easily reach a green space had less stress and a lower body mass. Similar results were reported in a study of more than 3,000 inner-city children in the United States.
  • A 2005 American Journal of Medicine article reported that people with ready access to parks or open spaces were 50 percent more likely to adhere to a regular walking regimen.
  • A 2010 UK study in Environmental Science and Technology showed a positive dose-response relationship between exercise in nature and mental health, particularly for young subjects. 
  • Runners reported lower levels of stress and depression when exercising in nature than when exercising in an urban setting.


As I have been slowly recovering over the past few weeks, I have truly appreciated the urban forest outside of my windows. Not only does it offer a pleasant view that blocks the busy highway, but it also offers habitat for wildlife that allows me to enjoy the song birds and rhythmic tunes of the cicadas — helping to bring a sense of peace and relaxation to my environment as I recover.

Have you ever felt that your urban forest helped improve your stress, recovery or overall state of mind?

A Hoot in the Forest

by American Forests

By Michelle Werts

One of my very first “science” reports back in elementary school was on the snowy owl. Years later, that same school system would introduce me to dissection via an owl pellet — much, much better in my estimation than the cliché of a frog. Through these formative school experiences, I’ve always had a soft spot for owls, so when news broke last week about the discovery of two new owl species — made by an assistant professor at my alma mater no less! — I immediately wanted to learn more.

In a paper in the current issue of Forktail, Journal of Asian Ornithology, researchers revealed that two owls long thought to be simple subspecies of Ninox hawk-owls are actually species in their own right. What caused this breakthrough? Bird song.

According to the paper’s lead author Pam Rasmussen, a Michigan State University assistant professor of zoology, in a release about the breakthrough, “The owls don’t learn their songs, which are genetically programmed in their DNA and are used to attract mates or defend their territory; so if they’re very different, they must be new species. When we first heard the songs of both owls, we were amazed because they were so distinctly different that we realized they were new species.”

The first of these new owls is named the Camiguin hawk-owl, after the island where it’s found: Camiguin Sur in the Philippines. An interesting, distinctive characteristic of this owl — besides its song, of course — is its blue-gray eyes, as it’s the only known owl species to have eyes that color. The second new species is actually an owl long thought to be extinct: the Cebu hawk-owl, named after the Philippine forests it calls home. Before its vocalizations were studied, scientists simply thought the Cebu hawk-owl was a subspecies of another hawk-owl.

If you’re curious about what these unique bird songs sound like, Michigan State’s Avian Vocalizations Center has them available for a listen. Who knew that a hoot could be so informative?
