    Conifers in the Urban Landscape: Application

    By J. Casey Clapp, Rick W. Harper, and H. Dennis P. Ryan III         

    The basis for proper function is proper design. When designing an infrastructure system for a municipality, engineers and planners must take many different criteria into consideration to ensure that the system functions correctly and accomplishes the given objectives for that site or region. These criteria may include efficiency, costs and returns, current or future conflicts, and components available for use. The urban forest, as a part of the infrastructure system of a municipality, is no different. Just as when civil engineers take on the task of building a road network, urban foresters should strive to create an urban forest network that works as efficiently as possible, avoids major conflicts, provides a high return, and uses the best tools available.

    In our introductory article (January 2015), we discussed some of the benefits associated with the use of evergreen conifers in urban plantings. These benefits include helping to increase the tree species diversity of the urban forest, increasing annual rainwater interception and annual pollution absorption, and the promotion of urban wildlife diversity. In this article, we will discuss important considerations that must be taken to ensure that conifers add value to the urban forest. It is important to use these different infrastructure components in the appropriate places; it is important to properly design the urban forest to ensure its optimal functionality.

    Due to seasonal changes and tree functional type (e.g. evergreen conifer, broadleaf deciduous, broadleaf evergreen), some trees provide services during certain times of the year, while providing less of those services – or even disservices – at other times. For instance, an evergreen tree provides summertime shading, which is generally regarded as a positive attribute, but also wintertime shading, which may be a negative attribute. A deciduous tree, however, provides this same summer shading benefit, but does not maintain a thermal buffer or privacy barrier during the wintertime, which can be a negative attribute. These types of attributes must be considered in order to design and implement a dynamic and effective green infrastructure system.

    Wintertime shading is a notably important aspect to consider when planting evergreen conifers in the urban landscape in New England, and most notably when planting them as street trees. Ice buildup on roads can cause significant issues, so it is necessary to allow for optimal winter sun exposure on streets. In New England, the sun strikes on the southern exposure and casts shadows to the north. Thus, planting evergreen trees on the south side of an east-west-oriented street will cause a shadow to be cast over the street during the winter (Fig. 1.). This conflict may be avoided, however, by planting evergreen species on the north side of the street and deciduous species on the south side. By employing this technique, one can obtain greater tree species diversity and the same year-round ecosystem services that were discussed in part I, while still gaining beneficial winter sun exposure. Furthermore, shade-tolerant evergreen conifers may be established within the vicinity of a permanent object (i.e. building) that is already casting shade. Because the road is already shaded, the evergreen conifer does not cause further shading, but does contribute positive ecosystem services. By taking sun exposure and aspect into account, conifers can be included as street trees without causing conflicts by way of disservices during winter. In addition to proper placement along streets and travelled areas, installations of evergreen conifers may be designed to function as living screens.

    Due to their dense, evergreen foliage, many evergreen conifers can efficiently block sight, sound, and wind. By using evergreen conifers as thermal buffers and wind blocks around a building, the building’s efficiency can be increased by up to 25% by limiting the amount of heat loss due to cold air infiltration, or by the cooling of the building shell via passing wind. Used as audio or visual barriers, evergreen conifers can also help to muffle unwanted road noise from highways and block unsightly views. Salt-tolerant species of conifers can also act as buffers between roads and nearby areas that may be sensitive to road salts. By planting evergreen conifers around freeways, the noise, sight, and salt pollution can be better contained to those areas. Evergreen conifers can also absorb pollution and particulate matter that is emitted from highway traffic and block water spray continuously throughout the year. Though the buffering benefits from evergreen conifers are obvious, they may also be planted as part of a strategy to help decrease the urban heat island effect often associated with urban settings.

    It has been shown that outdoor spaces with high leaf area indexes (LAI) have lower soil, surface, and ambient air temperatures. LAI is a measure of how dense a tree canopy is, or how much leaf cover is present over a given unit of area. The higher the LAI, the denser the tree cover is. Studies have found that areas with high LAI have cooler soil and surface temperatures by 7°C (12.6° F) and 6°C (10.8° F), respectively. Many conifers maintain dense crowns year-round with high LAI. Planting evergreen conifers therefore helps to keep small outdoor spaces, or microclimates, cool. By cooling enough of these microclimates throughout the urban environment, the macroclimate may also be influenced positively, and the urban heat island effect can begin to be addressed.

    According to inventory data from across the United States, conifers appear to be notoriously underrepresented as street trees. Of the trees inventoried in Portland, Oregon (just under 40,000), only 2.2% were determined to be evergreen conifers. Chicago, Illinois featured only about 9.1% coniferous street trees, while Boston, Massachusetts had no conifers listed in their top 25 species that comprised 96.7% of their street trees. Minneapolis, Minnesota featured only 0.3% conifers, Charlotte, North Carolina 8.5%, and Berkeley, California featured only 4% conifers in their community tree inventories. These numbers equate to the simple fact that cities are not taking full advantage of the benefits that may be derived from increasing their numbers of evergreen conifers.

    Urban populations derive numerous personal benefits from urban greenery that include reduced stress and increased quality of life, as well as healthier birth weights for newborns and more productive workplaces in what can potentially be more aesthetically-pleasing communities. Indeed, at no point are the aesthetic benefits of evergreen conifers more apparent then when deciduous leaves have turned brown and the trees themselves have become barren. Our hope is that evergreen conifers grow to become better recognized as key components of green infrastructure systems that can offer significant returns through their ecosystem services when they are incorporated into the design and installation of the contemporary urban forest.

    ——————-Species Spotlight————————–

    Invasive Species

    By Mollie Freilicher, MA-DCR Community Action Forester

    This month our focus is not on one species, but on two of six prohibited trees in Massachusetts. Under authority from Massachusetts General Law, including but not limited to, Chapter 128 Section 2 and Sections 16 through 31A, the Massachusetts Department of Agricultural Resources (MDAR) derives the authority to ban the importation, propagation, and sale of plants the Commonwealth has deemed noxious weeds. In 2006, MDAR, in collaboration with the Massachusetts Invasive Plant Advisory Group (MIPAG) identified 140 plants to be included on the newly created Prohibited Plants List. On January 1, 2009, the prohibitions were fully put into effect. The list includes herbaceous and woody and terrestrial and aquatic plants. The ban does not impact plants already in the landscape. It is poor practice, and unlawful, to plant any of the plants on the list. For native alternatives, check out this list from the New England Wildflower Society: http://www.newfs.org/docs/docs/invalt2.pdf.

    In this issue, we’ll cover Norway maple, sycamore maple, and tree of heaven and we’ll cover the remaining four in future issues. For the full list of prohibited plants, go the website: http://www.mass.gov/eea/agencies/agr/farm-products/plants/massachusetts-prohibited-plant-list.html     

    Norway maple (Acer platanoides)

    Sycamore maple (Acer pseudoplatanus)

    Tree of heaven (Ailanthus altissima)

    Amur cork-tree (Phellodendron amurense)

    Common buckthorn (Rhamnus cathartica)

    Black locust (Robinia pseudoacacia)

    Species summaries are adapted from Virginia Tech.

    Form: Medium-sized tree to 80 feet tall, usually with a dense rounded crown.

    Leaf: Opposite, simple, palmately-veined, 5-7 lobed with long pointed teeth, dark green above, paler below; exudes milky white sap from the petiole when detached. A purple-leaf variety known as ‘Crimson King’ is widely planted.
    Flower: Species is dioecious (male and female flowers on separate plants); bright yellow-green in color and somewhat showy, appearing early in the spring before the leaves.
    Fruit: Widely divergent 2-winged samaras, 1.5 to 2 inches long in clusters, relatively flat seed cavity, mature in late summer and persist into the winter.
    Twig: Stout, brown with a large, dullish, buds that are initially green, maturing to purple.
    Bark: Gray-brown, a bit corky, on older trees shallowly furrowed with long narrow, somewhat interlacing ridges.
    Where you’ll find it: Widely planted as a street tree, escapes to natural areas. 

    Sycamore maple

    Native to Europe and Central Asia

    Form: Medium-sized tree, 40-60 feet tall, sometimes taller, usually with a wide-spreading crown and short trunk.

    Leaf: Opposite, simple, 5-lobed, 5-6 inches long and broad, palmately-veined, coarsely serrate, heart-shaped base, dark green above and considerably paler below.
    Flower: Species is monoecious (male and female flowers on same plant); yellow, in a 3 to 5 inch hanging cluster.
    Fruit: Pair of samaras, spreading at about a 45 degree angle, each about 1.5 inch long, mature in late summer to early fall.
    Twig: Moderate to stout, glabrous, greenish brown, leaf scars do not meet; buds are large and broad, green, with large scales.
    Bark: Gray-brown to red-brown, breaks up into large scales that often exfoliate to reveal orange.
    Where you’ll find it: Planted as a street tree, especially along the coast, due to its tolerance of salt. Escapes into natural areas.

    Massachusetts Tree Wardens and Foresters Association

    Celebrate Arbor Day with tree seedlings!

    The Massachusetts Tree Wardens and Foresters Association sponsors an annual packaged seedling program as a popular way to help municipalities, garden clubs, businesses, arborists, and other interested individuals and organizations promote Arbor Day and to raise money for the Mass. Tree Warden Scholarship Fund. Available are a variety of shade trees, ornamentals, and conifers. All seedlings and transplant prices include bags, ties, shipping, and handling. The minimum order is 100 seedlings, and the ordering deadline is April 15, 2015. For more information, go to http://masstreewardens.org/arbor-day-seedling-program/.

    Conservation District Seedling Sales

    Massachusetts Conservation Districts sponsor spring seedling sales to raise money for district programs. A conservation district is a legal subdivision of state government, responsible under state law for conservation work within its boundaries. Boundaries in Massachusetts are along county lines. Conservation districts work with the Natural Resource Conservation Service to protect soil and water resources across counties in Massachusetts. They often sell a variety of trees and shrubs in small sizes. Below are links to some of the conservation district seedlings sales in Massachusetts.

    Tree City USA

    *Important Reminder about Tree City USA Program Requirements* –To receive the Tree City USA award, your community must conduct an Arbor Day ceremony and issue an Arbor Day proclamation each year. We urge you to use this requirement to the advantage of your community forestry programs by conducting a timely and well-considered ceremony, such as a tree planting at a local school in conjunction with the reading of the proclamation by local municipal leaders. This is just one of the many possibilities for recognizing and celebrating Arbor Day and bringing attention to the community forest and your efforts to protect and manage it with care.

    Other requirements for Tree City USA are a tree board or department, a tree ordinance (which many Massachusetts communities satisfy with Chapter 87 of Mass General Laws), and a community forestry program with an annual budget of at least $2 per capita. For information on how your community can apply this year, contact Mollie Freilicher, Community Action Forester, mollie.freilicher@state.ma.us.

    Witness Tree

    In February, Lynda Mapes, a Bullard Fellow at Harvard Forest, presented on her forthcoming book, Witness Tree. Mapes is a nature/environment reporter for the Seattle Post-Intelligencer and has been living in Massachusetts, first as a Knight Science Journalism Fellow at MIT and currently at Harvard Forest as a Bullard Fellow.  Her presentation outlined her book and the collaborations she has had while at Harvard Forest.

    From the Harvard Forest website: 

    During her 12-month Bullard Fellowship at the Harvard Forest, veteran newspaper journalist and author Lynda Mapes is taking a deep, long look at one tree: a 100-year-old red oak. With the help of Harvard Forest collaborators John O’KeefeAndrew RichardsonDavid Foster, and other experts, Lynda is probing the human and natural history of “BT QURU 03,” a tagged, tracked red oak in a long-term phenology study at the forest. Her goal is to learn what one tree can tell us about our changing world, and our relationship to nature. The result will be her forthcoming book, Witness Tree, under contract with Bloomsbury Publishing.

    Lynda chose Harvard Forest because she wanted to research and write the book through a deep immersion experience. In her own words: “Writers need three things to tell a story well: characters, location, and a narrative, and with the forest’s unique long-term historic records and scientific data; beautiful setting, and crack collaborators – including one spectacular tree — I have all three. Living in my research site, a short walk from my tree, on the historic John Sanderson Farm couldn’t be a better way to tell this story of a changing natural world, and our relationship to it.

    Tree Maps Showing the State of American Forests in 1884

    By Rebecca Onion

    These tree maps, commissioned by the United States Census and published in 1884, were compiled at the direction of dendrologist and horticulturist Charles Sprague Sargent. The complete set of 16 maps, digitized by the David Rumsey Map Collection, represents American forests by genus of tree, density, and position. The USDA estimates that while the total area of forested land in the United States has diminished by 30 percent since the date of European settlement in 1630, “75 percent of net conversion to other uses occurred in the nineteenth century.” Sargent’s project was meant to capture the contours of the forest as it stood in the Victorian era. 

    Sargent, a Bostonian and officer in the Union Army, was a professor of horticulture and the first director of the Arnold Arboretum at Harvard. As such, he was part of the first generation of professional American foresters; during his career, the Society of American Foresters, the U.S. Forest Service, and Yale’s School of Forestry and Environmental Studies were all founded.

    The International Space Station Will Soon Be Able to Measure Forest Density Using Lasers

    By Max Kutner

    February 2015—Yes, the future of the world’s climate is tied to the ability of forests to absorb atmospheric carbon. But exactly how well they can do that job depends on the density of the forests themselves, and scientists don’t have exact measures of that—yet. Soon they’ll have a new way to obtain that information from 268 miles above the earth. The Global Ecosystem Dynamics Investigation (GEDI) is a LiDAR, or laser-based, instrument being developed for the International Space Station. Once installed, in 2018, the $94 million device will beam three infrared lasers at earth, 240 times per second, or 16 billion times per year. Those light pulses will hit the forest floor and canopy, and the time that the reflections take to reach the space station will indicate the height of the trees. Three-D maps based on that information will lead to new estimates of forest biomass and, hence, the appetite for atmospheric carbon dioxide, consumed during photosynthesis.

    For Philadelphia and Baltimore, Parks Are Central to Livability

    February 3, 2015—“Many people think parks are easy, but parks are one of the hardest things for governments to do because of the physical and human aspects,” explained Peter Harnik, Hon. ASLA, director of The Trust for Public Land’s Center for City Park Excellence, while introducing a panel of experts at the New Partners for Smart Growth conference in Baltimore. The complex undertaking of how to best to create and maintain parks — for both governments and non-profits — is a thread that connected all speakers. Mark A. Focht, FASLA, first deputy commissioner of Philadelphia Parks and Recreation and former president of ASLA, gave an overview of the amazing progress made in Philadelphia’s expansive park system over the past few years. Some 80 percent of the city’s residents are already meeting Mayor Michael Nutter’s “goal of everyone being within a ten-minute walk away from a park.” Examples of recently built green spaces and amenities that help the parks department to reach all city residents include Paine’s Park, a skate park and public space; the Schuylkill River Dog Park; and the Schuylkill Banks Boardwalk.

    There’s a Whole World of Maple Syrup Beyond This Small-Town Massachusetts Sugarer

    By Kristin Toussaint 

    February 13, 2015—During the first blizzard of this season, Ron Kay was walking through the snow. He had work to do, and the looming storm couldn’t keep him from checking his maple syrup taps. Despite it being 18 degrees, Kay, 68, spent five hours outside, alone on a snowy hill scattered with sugar maples. Kay taps trees throughout the surrounding woods of Maynard, even going into neighbors’ yards to get access to all the sap in town. He runs rubber hosing from tap to tap, and collects all the sap in a stainless steel tank. The tubing crisscrosses his neighbors’ backyards like fallen power lines. They don’t mind; Kay is a central figure of the community. He’s owned Maynard Maple Farms for over 30 years and has been sugaring for even longer. He tapped his first tree 61 years ago.

    Researchers Unlock New Way to Clone Hemlock Trees Able to Fight Off Deadly Pest

    By Sandi Martin

    February 2, 2015—In a new paper published in Trees-Structure and Function, researchers in UGA’s Warnell School of Forestry and Natural Resources outline how they were able to generate hemlock tissue cultures, cryogenically store them and then grow plants from the cultures after thawing them several months later—the first to successfully do so. As part of their efforts to freeze the germplasm, they also developed a method that will allow them to clone hemlocks, particularly important as they seek to propagate trees naturally resistant to the insect that has destroyed millions of hemlocks in 18 states since it was accidently introduced into the eastern U.S. Read more at: Phys.org.

    Urban Pollinators Get The Job Done

    By Jonathan Morales

    February 12, 2015— A new study from San Francisco State University shows that native bees are able to provide adequate pollination service in San Francisco, despite the urban setting. And, in what appears to be good news for farmers in space-starved cities, the amount of pollination a plant received was driven not by how large the garden was, but how densely it was populated with flowers.

    The research was published Jan. 15 in the journal Urban Ecosystems. Read more at: Phys.org.
