The Practical Science of Planting Trees: Part I
By Rick Harper and Mike Davidsohn
As Extension Faculty, we are familiar with lecturing to students in the classroom, and more typically to audiences, large and small, comprised of adult practitioners. This fall I have had the chance to interact with some larger audience groups at the Canadian Urban Forestry Conference in Laval, QC, and the Tree Care Industry Association Conference in Baltimore, MD, and the Society of Municipal Arborists in Indianapolis, IN. I had the opportunity to interact with professionals from across North America and around the world. Throughout question and answer sessions, I was intrigued that even though we live in the information age, we are still very much in search of good information that can be easily interpreted and readily applied. Especially when it comes to the practice of selecting, planting, and getting the most of our investment in our urban trees. One guide that I found myself regularly referencing in relation to reoccurring questions and themes was the updated text: The Practical Science of Planting Trees by G.W. Watson and E.B. Himelick (2013, International Society of Arboriculture, Champaign, IL. 250 pp.).
This text (Watson and Himelick, 2013) has much to say about the proper evaluation of a plant before it is purchased. According to Cornell University’s Urban Horticulture Institute (UHI), approximately 90% of urban trees that are planted in the Northeast are field grown, dug mechanically with a tree spade or manually by shovel, when the tree reaches the salable size of approximately 2.5 inches, and then wrapped to preserve the intact soil, with burlap, twine and wire basket (balled-and-burlap or B&B) (N. Bassuk, pers. comm.). Hence, here we will explore what Watson and Himelick report related to selection of B&B trees.
The origin of a tree at the nursery is important. While trees may be produced here in the Northeast under local climatic conditions, local nurseries also purchase large quantities of trees from nurseries located in the more southerly Mid-Atlantic states, the Midwest, and extreme Pacific Northwest. In addition to challenges adapting to our climate here in the Northeast, information pertaining to seed source (i.e., where the tree specifically came from) and root stock may be limited or unavailable. According to the USDA Plant Hardiness map, Massachusetts features a climate that ranges from a relatively moderate 7b to a significantly colder 5a. Utilizing trees grown under these local conditions may minimize plant adaptation time and increase the chances of achieving a healthy urban tree planting. Additionally, when selecting trees at a nursery, identifying the orientation of the tree (i.e., north) so that the tree may be placed in like manner at the time of planting is a recommended practice to help prevent sunscald.
Concerning root location, quality, and formation relative to B&B-production method, it is of utmost importance that two or three main roots and the root flare be located so that the tree can be installed correctly. According to a survey produced by a major tree company, 93% of the newly-installed trees inspected featured excessive soil (more than 3”) covering tree roots. It has also been noted that a majority of trees leaving the nursery will also feature excessive soil on top of the tree roots. This is something that practitioners who will be installing trees need to consider. Although detection of root imperfections may not be practical, spot-checking a select number of B&B trees (5% - 20%) can allow for a full visual inspection of the root system, where consideration should be given to inspecting for radial/lateral root production, the presence of a taproot (generally not desired), and other root-related imperfections. One key benefit associated with B&B production is that mechanical injury of roots often occurs less because of the volume of soil protecting the lower portion of the tree. A final perspective concerning B&B trees is the diameter of root ball associated with the trunk size. All too often, trees that I have dug up that have performed poorly or simply died have not had the volume of root material needed to support the above-ground portion of the tree. Though technical specifications exist from the American Standard for Nursery Stock concerning root ball diameter as the caliper of the trees increases by every 0.5”, a general rule of thumb that can be used in the field is that for every inch of stem diameter there needs to be at least 10” of corresponding root ball diameter.
In terms of the above-ground portion of the tree, the better the branch structure, the less intervention, such as pruning, will be required after the tree is planted. Branches should be well-spaced (vertically and three-dimensionally) and feature strong, wide attachments that will foster sound growth and development. Trees with codominant leaders should not be selected or pruned. Foliage should be inspected for the presence of insects or disease or potential evidence of nutrient deficiencies (i.e., iron chlorosis, manganese deficiency). The principles that apply to B&B selection also apply to trees that are produced using differing methods, like container-grown, bare-root, or in-ground fabric systems.
We will continue next time with Watson and Himelick’s review of planting, guying, and transplanting a tree.

Dawn Redwood, Metasequoia glyptostroboides
By Mollie Freilicher, DCR Community Action Forester
Dawn redwood is a tree with a relatively recent history in the planted landscape. It was only known from fossils until the 1940s when a forestry professor, T. Kan, from the National Central University in China, noticed a tree in Wan Hsien that was locally known as “water fir.” He had not seen it before and thought it might be something notable. It was several years before botanists collected samples and identified the tree as being in the genus Metasequoia, a genus previously known only from the fossil record. [For a full account of the discovery, see H.H. Hu 1998-1999]. Seeds of Metasequoia came to the Arnold Arboretum in 1946 and were distributed to institutions around the United States and around the world. Dawn redwood made its scientific debut in a February 1948 issue of Science, where E.D. Merrill wrote about Metasequoia in the wild, “It is clear, however, that this sole living representative of a very ancient genus is now apparently on the verge of extinction.” While the species continues to be endangered where it naturally occurs in Chongqing, Hubei, and Hunan provinces in China, it now occurs in countries with temperate climes all around the globe, including right here in Massachusetts where you can go see a tree grown from one of the original seeds brought to the Arboretum. The tree from which the seed had been collected in the wild, grew along the edge of a rice field in Modaoqui in Hubei province. Now the seedling is a tree with a 91-inch diameter at breast height, along the Conifer Path.
In its native area, in parts of Chongqing, Hubei, and Hunan provinces, dawn redwood grows in floodplains and occupies habitats similar to those baldcypress (Taxodium distichum) would occupy. Here in the United States, dawn redwood is hardy in zones 4-8 and grows in a variety of soil conditions in the landscape. It is a fast-growing tree and can reach heights of 70 to 100 feet, with a spread of 25 feet.
Similar to baldcypress, dawn redwood is a deciduous conifer, losing all its leaves in the fall. Unlike baldcypress, leaves of dawn redwood are opposite—a good way to distinguish these somewhat similar-looking trees. Leaves are flattened, ½-inch long, bright green above, paler below, and arranged pectinately. Buds are opposite, ovoid, with brown scales, and are often paired at the base of branchlets. Branchlets on dawn redwood can be deciduous or persistent. The persistent branchlets are reddish brown and have many buds, but only some leaves. Deciduous branchlets grow off of perisistent branchlets and contain leaves. In the fall, leaves can turn orange-brown to red-brown, before becoming all brown in autumn, and falling off the tree.
Dawn redwood is monoecious, with both male and female flowers on a single tree. Male flowers are in clusters—racemes or panicles, while female flowers are solitary. Cones are pendulous and elongated or round, ½ to 1-inch long and mature in the fall. The structures that contain the seeds kind of resemble lips (a bit more so than the fruit of Sequoia, though that fruit is similar).
Dawn redwood does not have significant disease or insect problems, though the top can die back in extreme cold. Dawn redwood transplants well and does best in full sun, in moist, well-drained, acidic soil. Dawn redwood makes a great specimen tree for a park, campus, golf course, or other large area and multiple trees can be grouped for a dramatic effect or used for an alleé. New York, and here in Massachusetts, Springfield, (and other cities too), have used it as a street tree. New York City Parks approved the species for use in medians and narrow growing spaces because of its pyramidal form.

Mass Tree Wardens’ and Foresters’ Association 104th Annual Conference
January 10-11, 2017, Sturbridge, MA
featuring Dr. Erika Svendsen, U.S. Forest Service
Cultivating Civic Stewardship of the Urban Forest
Public shade tree committees and other urban forest groups can be a tree warden's biggest thorns or strongest advocates. At their best, they are a welcome source of civic participation, marshaling support for community trees and for the funding to help manage them. Dr. Svendsen will focus on urban natural resource stewardship as a means to strengthen social trust, enhance civic participation, and foster innovation in urban and community forestry. She will describe specific instances where communities have used urban greening as a catalyst to recover from different types of disturbances and will illustrate how data from such events can be shared with policy makers.

2017 DCR Arbor Day Poster Contest
“Trees are Terrific...from Berkshires to Bay!”
Each year, over 1,500 Massachusetts fifth graders participate in the Arbor Day Poster Contest. Each school holds its own poster contest and submits their winning poster to the DCR. Prizes include art supplies, ice cream, and a tree for the winner’s school. Each year there is a theme to encourage students to think about trees in new ways, such as “Trees Grow with Us and for Us” (2016), “Trees are Champions in My Community,” (2015), or “Celebrate a Tree” (2012.) The theme for 2017 is “Trees are Terrific…from Berkshires to Bay!” The deadline for the 2017 contest is March 15, 2017.
UMass Summer College--Help Spread the Word
There’s a shortage of qualified workers in the tree care industry; many of you have probably experienced it firsthand. Training new employees who have no experience takes time away from production; hiring employees who have at least a basic understanding of arboriculture means the new hires can get up to speed on the crew more quickly. Not all new hires will have the benefit of a Stockbridge / UMass Arboriculture degree, but we can give them a good start. For the past three summers, UMass and Stockbridge have offered a “pre-college” course in Arboriculture & Urban Forestry for high school students. In the course, students get an overview of the Arboriculture & Urban Forestry curriculum that two- and four-year students at Stockbridge and UMass take. We hope to offer the course again this summer, but we need enough students to cover the costs. The course will run for one week (35 hours of training—in the classroom and in the field) in July 2017.
During the course, students learn the importance of safety, basic tree biology and soil science, how to identify trees, how to manage insect and disease pests, how to prune and fertilize, and of course, some basic tree climbing skills. Typically, we spend the mornings inside, in a classroom, and then the afternoons outside climbing and learning how to identify trees. In addition to the course itself, UMass provides a typical college experience for students, who live in dorms (unless they choose to commute from home), eat at the dining commons, and participate in supervised social activities with classmates. There are several other pre-college programs going on at the same time, so there are lots of other high school students to meet and make new friends.
All of the previous students who enrolled really liked their experience. We think the course is an excellent introduction to our profession, a way to attract young people to a great career, and a good way to recruit students to attend Stockbridge and UMass.
We need your help to reach out to high school students and encourage them to participate. Students don’t have to have any experience or special skills, just a good attitude and an interest in learning about trees and being outside.

Gypsy Moth Outbreak of 2016
By Joe Elkinton and Jeff Boettner
This article appeared in the No. 3, 2016 issue of Massachusetts Wildlife Magazine.
For the first time in 35 years, widespread and severe tree defoliation by gypsy moths surged across Massachusetts, Rhode Island and Connecticut. This came as a surprise to researchers whose subsequent investigations revealed the outbreak is linked to the recent and severe statewide drought. The authors describe the introduction, spread, and population ecology of gypsy moths, and the past and current efforts to battle this exotic invasive.
The gypsy moth (Lymantria dispar) is a native of Europe and its history in North America compared to many exotic species is unusual in that we know exactly when and where it was introduced. The culprit was Etienne Leopold Trouvelot of Medford, Massachusetts, an amateur entomologist who later became famous for his astronomical illustrations of celestial objects and phenomena. He was trying to hybridize gypsy moth with native silk moths for the silk industry. He imported gypsy moths from France and they escaped from his home in 1868 or 1869. The first tree defoliation by these moths started in Medford and spread to surrounding towns in the 1880s. In 1890, the Massachusetts legislature earmarked funds for gypsy moth control and eradication. These efforts did not succeed and gypsy moths continued to spread, but very slowly, because even though female gypsy moths have wings, they do not fly. Only males fly. Instead, the females devote all of their energy to egg production, averaging 600 eggs per moth. Recently hatched larvae (caterpillars) spread from tree to tree by dangling from silken threads blown by the wind. Much of the actual spread of gypsy moth in North America is caused by human beings, who transport the overwintering egg masses on firewood, lawn furniture and other objects in their yards to other locations. It took over 50 years for gypsy moth to spread across Massachusetts. In 1922, a barrier zone was created along the Hudson Valley in an attempt to prevent the spread further south and west, but that effort failed. The gypsy moth spread is continuing today, with the leading edge of the infestation ranging from Minnesota in the Midwest to North Carolina in the South. It has taken 148 years for gypsy moth to attain its current distribution in North America. Read the full story at MassWildlife.

Interview with Mitchell Silver on NYC’s Game-changing Park System
By Jared Green
November 30, 2016—Check out this interview with the Commissioner of New York City’s park system. Hear about some new initiatives like “Parks Without Borders,” what happens when you remove chain link fencing around parks, and how parks can help protect the city from storms and floods.
“[…] park land represents 14 percent of the city’s footprint. Streets and sidewalks represents another 26 percent. So in other words, 40 percent of New York City is within the public realm. We own it, yet the average citizen does not know where the parks department property ends and the department of transportation property begins. And guess what? They don’t care. They want a seamless public realm.”

Spread By Trade and Climate, Bugs Butcher America's Forests
By Michael Casey and Patrick Whittle
December 7, 2016—Petersham, Mass. (AP) — In a towering forest of centuries-old eastern hemlocks, it's easy to miss one of the tree's nemeses. No larger than a speck of pepper, the Hemlock woolly adelgid spends its life on the underside of needles sucking sap, eventually killing the tree.
The bug is one in an expanding army of insects draining the life out of forests from New England to the West Coast. Aided by global trade, warming climate and drought-weakened trees, the invaders have become one of the greatest threats to biodiversity in the United States. Scientists say they already are driving some tree species toward extinction and are causing billions of dollars a year in damage — and the situation is expected to worsen. "They are one of the few things that can actually eliminate a forest tree species in pretty short order — within years," said Harvard University ecologist David Orwig as he walked past dead hemlocks scattered across the university's 5.8-square-mile research forest in Petersham. This scourge is projected to put 63 percent of the country's forest at risk through 2027 and carries a cost of several billion dollars annually in dead tree removal, declining property values and timber industry losses, according to a peer-reviewed study this year in Ecological Applications. That examination, by more than a dozen experts, found that hundreds of pests have invaded the nation's forests, and that the emerald ash borer alone has the potential to cause $12.7 billion in damage by 2020.

On the Edge: The Intersection of Forests and Developed Landscapes
December 19, 2016—Boston, MA– A new study shows that trees in the Boston region grow faster and store more carbon as biomass the closer they are to developed areas. As urban development spreads, patchy woods are increasingly the norm. “More and more of the landscape is becoming fragmented,” says Andrew Reinmann, a biologist at Boston University. Forests are important asset in fighting climate change, absorbing an estimated 30 percent of the carbon dioxide we emit from burning fossil fuels. But those estimates come from big forests, says Reinmann, and we know relatively little about how patchy forests function, and whether they provide the same services that large forests do. A study published on Monday in PNAS by Reinmann and BU environmental scientist Lucy Hutyra shows that forest fragments in New England behave differently than intact forests in surprising ways: they may pull significantly more carbon dioxide out of the atmosphere than predicted.
