Winter’s End, Spring’s Arrival:
The Annual Community Tree Conference at UMass
By Rick W. Harper
Out of the snowiest February on record for Massachusetts sprang forth the seasonal event that regularly attracts 250 urban foresters, commercial arborists, and shade tree committee volunteers: the University of Massachusetts’s Annual Community Tree Conference in Bowker Auditorium at Stockbridge Hall on the campus of UMass Amherst. Taking place on Tuesday, March 10, 2015, this year’s conference theme was Preserving Trees and Landscapes in a Changing Environment and highlighted the understanding, preservation, and protection of historic trees. As always, this event provided not only the occasion to hear from informative and enlightening speakers from across Massachusetts and the Northeast, but also provided important networking opportunities for its attendees.
Mollie Freilicher, Community Action Forester with the Massachusetts Department of Conservation and Recreation Urban and Community Forestry Program, started the day’s roster of speakers with an update about the state’s newly energized Big Tree Registry. She detailed the revitalization of this program and discussed various examples of noteworthy trees across the state – past and present. Her take-home message was straightforward: If you have a tree you feel may be of size to be possibly considered a “champion,” reach out to MA DCR and nominate it! Dave Hawkins, Consulting Arborist and Principal of Urban Forestry Solutions, enlightened attendees with a better understanding of how to appraise a tree – especially if it is of historical significance! UMass Extension turfgrass team leader Mary Owen updated attendees on Chapter 262, the legislation that was passed in 2012 authorizing the enactment of new statewide nutrient management regulations by the Massachusetts Department of Agricultural Resources. While, according to Owen, many aspects of this legislation are more oriented toward regulating nutrient-related activities on production settings like farms and nurseries, certain provisions may impact tree care professionals, depending on the locality within the state, and especially on whether professionals are applying fertilizers to lawns during certain times of the year. As of March 2015, the statewide regulations had not yet been released. The morning closed with a presentation from the National Parks Service about landscape restoration activities at the Springfield Armory.
Afternoon festivities included the handing out of scholarship awards to deserving UMass students by Bob Leblanc, President of the Massachusetts Tree Wardens’ and Foresters’ Association, Rich Herfurth President of the Massachusetts Arborists Association, and Chris Fallon from the Southeastern Massachusetts Tree Wardens’ and Arborists’ Association.
The afternoon slate of speakers commenced with William DeVos, Principal of Treeworks, based in Montpelier, VT. Bill’s talk –Pruning and Cabling to Preserve Historic Trees – discussed some of the many high-end cabling and bracing projects he has consulted on all over the country. His talk especially resonated with Arboriculture/Urban Forestry students, and many of them were talking about his lecture after the conference was over. Dr. Dave Bloniarz, USDA Forest Service Urban Forest Researcher and Director of the Urban Natural Resources Institute followed with a lecture about how the benefits of community’s urban forests increase over time and may be better understood using i-Tree. Finally, the day closed with a wrap-up from the UMass Extension Plant Diagnostic Laboratory Plant Pathologist, Dr. Nicholas Brazee. Nick detailed some of the samples the clinic received over the 2014 growing season and highlighted emerging plant diseases in New England, such as oak wilt and bacterial leaf scorch. While those two diseases are not yet in New England, Nick cautioned that they may be on the horizon. Nick also highlighted some of his current research on wood decay and carbon storage in trees. Throughout his talk, Nick discussed what changes may occur in the long-term, as climate conditions continue to shift in association with global climate change. Summing up the day’s events, Brazee offered this analysis: “This conference provides cutting-edge updates and the latest information for real-world practitioners like urban foresters, arborists, and plant enthusiasts who are trying to solve real-world problems in a time of environmental and regulatory change…I believe the regular robust attendance that we receive year after year is confirmation of the success of this conference and speaks clearly to the importance of this annual event.”
Congratulations to all involved in yet another successful conference!

Aronia arbutifolia, Red chokeberry
By Mollie Freilicher, MA-DCR Community Action Forester
This month, we examine a smaller specimen for our species spotlight: red chokeberry (Aronia arbutifolia). Red chokeberry is a member of the rose family and is native to Massachusetts. Its native range extends from Massachusetts, south to Florida, and west to Texas. It naturally occurs in bogs, swamps, woods, and lowlands, although in New England, it is more common to find it near the coast. It is hardy in zones four to nine. It is a multi-stemmed shrub, typically growing to six-to-ten feet high, with a spread of three-to-five feet. At maturity, it is wider than tall and has a distinct upright growth habit. It readily forms suckers and can form a mass that can be contained through pruning. The common name “chokeberry” refers to the raw fruits, which are somewhat astringent. Chokeberry is a different plant than “chokecherry,” the common name of Prunus virginiana. There is an effort among companies producing chokeberries commercially (often a related species A. melanocarpa) to call the berries “aronia berries” or simply “aronia,” to leave the negative connotations of having “choke” in the common name.
Leaves of chokeberry are simple, alternate, elliptic to obovate, 1.5-to-3.5 inches long, with an acute tip and minute teeth. Leaves are a shiny dark green color above and paler and tomentose on the underside. In fall, the leaves turn red, for a bright display of fall color.
Red chokeberry flowers in early May, with clusters of small, white perfect flowers in corymbs of 9-20 flowers. The bright red fruit, a pome, ripens in the early fall. It will persist through the fall and into the winter as it is not utilized by birds until later in the winter.
Red chokeberry is relatively free from disease and insect problems and does well in partial or full sun, though it will produce more berries in full-sun settings. Red chokeberry makes a great native addition to a border or naturalized area and is a great selection for massed plantings. It does well in a variety of soil types, both wet and dry. ‘Brilliantissima’ is a commonly available cultivar known for shiny green leaves and bright red fall color.

Sustainable Urban Forestry—UMass Summer School
People Need Trees and Trees Need Care
Stockbridge School– UMass Summer School
July 13 - 17, 2015
UMass will offer a one-week course for high school students again in July 2015. The one-week intensive course is a balanced academic study of the science and business of arboriculture and offers an introduction to the basic skills required to work in the field with trees.
In addition to offering a first-rate introduction to arboriculture to the high school students who participate, the organizers are hoping to recruit some of them to attend Stockbridge and UMass.
Arborists are in great demand in many towns and cities because it is important to properly plant and maintain trees. There are currently multiple career opportunities for graduates with either a two- or a four-year degree in Arboriculture & Urban Forestry from UMass-Amherst. Even if they choose not to attend Stockbridge, some students may enter the arboricultural workforce with good skills, or at least become better consumers of arboricultural services as adults.

Chasing the Red Queen: The Evolutionary Race between Pests and Poisons
Andy Dyer, PhD, Associate Professor of Biology, University of South Carolina, Aiken
1 Session: Wednesday, June 10, 7:00–8:30pm
Location: Hunnewell Building
In Through the Looking Glass, the Red Queen tells Alice she must run as fast as she can, just to stay in place. Modern agriculture, with its almost total dependence on chemical pesticides, is the Alice of today. Try as we might, our every attempt to control insects and weeds is met with an evolutionary response: they adapt and become resistant to the poisons. We fight back with new, improved chemicals—they respond by adapting again, and on it goes, over and over, as it has for the past sixty years. But Andy Dyer believes that if we use the principles of evolutionary biology, we stand a good chance of taking control of our food supply and weaning our agricultural system from chemical dependence. Join us for a biological perspective on securing foods of our future.
Fee $5 member, $10 nonmember
Pruning Project: Taming the Early Season Bloomers
Jen Kettell, Arborist and Horticultural Educator
1 Session: Monday, June 15, 6:30–8:30pm
Location: Hunnewell Building
Now is the time to prune those early-blooming shrubs--once they’ve flowered--so their growth through the summer can fuel the development of next year’s buds. ISA-certified arborist Jen Kettell will focus your attention on the kinds of shrubs that should be pruned now, various pruning cuts, and the type of thinning that will encourage health and vibrant blooms for years to come.
Fee $25 member, $35 nonmember
In the Groves: A Summer Solstice Journey
Diane Edgecomb, Storyteller, and Margot Chamberlain, Celtic Harpist
2 Sessions (select one): Friday, June 19, or Saturday, June 20, 6:30–8:30pm
Location: Hunnewell Building
Join us for an enchanting evening of Tree Myths, Songs, and Summer Solstice Legends. Diane and Margot spin tales of the human connection with trees and the deep meaning we have assigned to them through the ages. This unique performance, designed specifically for the Arnold Arboretum, travels through the Arboretum with story and music. Each story is told under a different tree or among a unique collection of Arboretum plants. The program begins under a grand Cedar of Lebanon, moves into the rosaceous collection, to the oaks of Bussey Hill, then onward to Hemlock Hill, culminating with the haunting Czech legend “The Wild Woman of the Birch Grove,” told amid the birches at sunset. Appropriate for adults and for children twelve years and above. Bring a cushion to sit on if you wish. Registrants will walk approximately two miles on and off trails on uneven terrain. The performance takes place rain or shine. In the event of rain, it will be held in the Hunnewell Building lecture hall. Register early for this popular event.

Climate Action Plan Toolkit:
EPA Releases Stormwater Climate Change Tool
Release Date: 02/13/2015
Contact Information: Cathy Milbourn, firstname.lastname@example.org, (202) 564-7849; Contacto en español: Lina Younes, email@example.com, 202-564-9924, 202-565-4355
WASHINGTON – As part of President Obama’s Climate Action PlanVirtual Climate Resilience Toolkit, the U.S. Environmental Protection Agency (EPA) announced the release of the Climate Adjustment Tool for EPA’s Stormwater Management Model (SWMM) – a widely-used, downloadable online stormwater simulation model. The Climate Adjustment Tool allows engineers and planners to evaluate the performance of water infrastructure while considering future climate change projections, such as more frequent high-intensity storms and changes in evaporation rates of seasonal precipitation, to determine the benefits of resiliency decisions to reduce local economic burden and protect communities.[…]
EPA’s Stormwater Management Model is used throughout the world for stormwater runoff reduction planning and analysis and design of combined and sanitary sewers, as well as other drainage systems. Originally released decades ago, SWMM is now used in thousands of communities throughout the world, including as the core modeling engine in cities such as Philadelphia, Cincinnati, Indianapolis, and Seattle.
To assist community planners and managers in determining resiliency and sustainability actions that will help protect against extreme weather and reduce the local economic burden after a natural disaster, EPA has developed additional tools, including:
EPA’s Stormwater Calculator- a tool that can be used by homeowners, landscapers, and developers to estimate the amount of rainwater and frequency of runoff on a specific site based on local soil conditions, land cover, historic rainfall records, and climate change scenarios.
For more information on the complementary National Stormwater Calculator, visit:
EPA’s Climate Resilience Evaluation and Awareness Tool (CREAT)- a tool that assists drinking water and wastewater utility owners and operators understand potential climate change threats and assess the related risks.

It's called the spotted lanternfly (Lycorma delicatula). This Asian native was first confirmed in the United States in September 2014 in Berks County, Pennsylvania. The Pennsylvania Department of Agriculture and Pennsylvania Game Commission jointly made the positive identification.
"Since Pennsylvania is the first known home to spotted lanternfly in North America, we're taking every possible precaution to stop its spread and eliminate this threat to agriculture," said State Agriculture Secretary George Greig in a press release.
Billionaire Barry Diller's $130 Million Floating Park in The Hudson Is Actually Going To Get Built, And It Looks Incredible
February 12, 2015—Media mogul Barry Diller and his wife, fashion designer Diane von Furstenberg, have committed to funding a floating public park and performance space on a pier in the Hudson River. Their pledge of over $113 million will be the single largest private donation to a public park in New York City history, according to Capital New York. And now, the project will officially be built after a unanimous vote by the Hudson River Park Trust approving the plan on Wednesday, according to DNAinfo. Construction will begin on the park in 2016, and it is expected to be completed by 2019. According to DNAinfo, "more than half of the performances in the pier's amphitheater will be free or 'low-cost.'" The new addition to the waterfront will be called Pier 55 and is expected to cost more than $130 million. The City of New York will provide $17 million to the project, while New York State will provide a separate $18 million for the construction of a public esplanade that will lead into the pier.

Satellite Data Suggests Forest Loss Is Accelerating
March 2, 2015—London (Thomson Reuters Foundation) - Satellite images suggest tropical forests from the Amazon to the Philippines are disappearing at a far more rapid pace than previously thought, a University of Maryland team of forest researchers say. The annual rate of deforestation from 1990 to 2010 was 62 percent higher than in the previous decade, and higher than previous estimates, according to a study carried out of satellite maps covering 80 percent of the world’s tropical forests. The new study questions the United Nations Food and Agriculture Organization's (FAO) assessment, which suggested that the rate of deforestation actually decreased 25 percent from 1990 to 2010. Until now, "the Forest Resource Assessment (FRA) report of the United Nation's FAO was the only one available source to estimate long term forest change and its trends," said Do-Hyung Kim, lead author of the study that is expected to be published in Geophysical Research Letters.

Turning Smartphones into Personal, Real-Time Pollution Monitors
Feb 18, 2015—As urban residents know, air quality is a big deal. When local pollution levels go up, the associated health risks also increase, especially for children and seniors. But air pollution varies widely over the course of a day and by location, even within the same city. Now scientists, reporting in the ACS journal Environmental Science & Technology, have used smartphone and sensing technology to better pinpoint where and when pollution is at its worst.

Key Genes For Symbiosis Between Mycorrhiza Fungi and Trees Evolved Several Times
February 24, 2015—Champenoux/ Halle(Saale)/ Leipzig. The life style of ectomycorrhiza fungi is some 100 million years younger than the one of their ancestors within white and brown rot fungi. The key genome adaptation enabling fungi to associate to roots for establishing a symbiosis evolved repeatedly over time. This conclusion was drawn by an international team of researchers who performed the first comprehensive comparative phylogenomic analysis on mycorrhiza fungi, now appearing in the reputed scientific journal Nature Genetics. These sequences provide crucial information on how the symbiosis between fungi and trees evolved. This will enable scientists to improve their prediction of the reaction of mycorrhizal communities to environmental modifications, such as changes in forest management or climate.

From Pecan To Walnut: American Leafminer Invades Italy on a New Tree
By Naturalis Biodiversity Center
February 3, 2015—A leafminer that has been invading Italian walnut orchards since 2010, has been shown to be identical to the North American species that feeds on hickories and pecan. The identity of these moths as Coptodisca lucifluella was proved by DNA barcoding and morphological study. Probably the moth invaded the new host plant after it invaded Italy. The leafminer is already widespread in Italy but the level of damage does not seem to be worrisome, experts report. Read the full story at phys.org.
New England’s Plants Face Significant Threat, Report Says
By David Abel
March 26, 2015—The lime-green flowers of the slender orchid known as the Small Whorled Pogonia used to bloom on forested slopes throughout New England, but they — and more than one-third of the region’s native orchids — are disappearing. In all, 22 percent of all native plant species in New England are now either extinct, rare, or in a state of decline, strangled by invasive vines, trampled by incautious hikers, or drowned by man-made dams, according to a landmark report released Thursday by the New England Wild Flower Society. The report also found that nearly a third of all the region’s plants are from elsewhere, and an increasing number are considered invasive, which means they are harmful to native flora. Read the full story at The Boston Globe or the report at www.newfs.org.
March 18, 2015—The price of olive oil is expected to rocket after the EU ordered the felling of millions of trees infected with a deadly microbe. Brussels has recommended that about 11 million olive trees in southern Italy, many centuries old, be chopped down. They have been infected with Xylella fastidiosa, a bacterium spread by an aphid. The disease, first identified in the Americas, has already wiped out a million trees in Salento, southern Puglia. It is feared that unless drastic action is taken to fell the groves, the bacterium will spread to other olive-producing regions of Italy, such as Tuscany and Umbria, and even to other Mediterranean countries. Read the full story at the Daily Mail. (The bacterium Xylella fastidiosa is native to the United States and causes bacterial leaf scorch on many species and Pierce’s disease on grapevine. The bacterium is not yet known to be in New England, but it is found as close as Delaware, New Jersey, and Pennsylvania. For more information, go to: http://www.na.fs.fed.us/fhp/bls/)
New York State Ban On Invasive Species Goes Into Effect
By Linda Rohleder
March 15, 2015—Many homeowners have breathed a sigh of relief, now that new regulations banning the sale, purchase, and transportation of a long list of invasive species that have plagued our properties — and our ecosystem — for years, has taken effect. As of March 10, it became illegal to buy, sell, or transport 126 species identified by the New York State Department of Environmental Conservation as invasive. The list includes 69 plants, 15 fish, 17 aquatic invertebrates (including several snails, clams, and snails), 13 terrestrial invertebrates (insects and land snails), five vertebrates (such as the mute swan) and seven species of algae, bacteria, and fungi . In addition, 29 species are “regulated,” meaning that, while they may be sold and transported, they may not be knowingly introduced on or near public lands or natural areas.
