Gypsy Moth: What to Expect in 2017
Following the widespread defoliation from gypsy moth last year, state environmental officials predict another season of higher than usual caterpillar feeding in 2017. Based on egg mass surveys throughout the state, gypsy moth populations may be above the low threshold seen in the previous decade. Recent drought conditions have limited the effectiveness of a soil borne fungus, Entomophaga maimaiga, which has helped keep populations in check since the last large outbreaks of the 1980’s. The 2016 gypsy moth population boom caused over 349,000 acres of damage statewide in Massachusetts. Damage ranged from light feeding and minimal leaf loss to severe damage with total stand defoliation.
Gypsy moth populations in Massachusetts have generally experienced cyclical patterns and have been controlled by natural factors, including weather, natural and introduced enemies, and the resilience of our forests to withstand defoliation. Though trees are able to overcome a defoliation event, successive years of severe insect feeding or the addition of other stressors such as drought, can lead to long-term tree damage or mortality. In areas that have seen repeated defoliation by gypsy moth, forest health specialists recommend targeted treatments using a biological control pesticide such as Bacillus thuringiensis spp. Kurstaki (BT) to reduce populations to manageable levels. Individuals interested in pursuing treatments should hire a licensed arborist or pesticide applicator to protect their trees in a safe and effective manner.

The gypsy moth has been a costly and persistent problem in Massachusetts since its introduction in 1869. Despite control efforts by federal and state agencies, gypsy moth populations continue to defoliate our forests here in Massachusetts and expand their range in the U.S.
Life Cycle and Identification
Gypsy moths have one generation per year. During their lifecycle they complete four distinct life stages: egg, larvae (caterpillar), pupae, and adult (moth).
Egg: Female adult moths lay egg masses by early August on trees, houses, outdoor furniture, or cars where they will overwinter. Egg masses are buff colored, approximately 1-1.5 inches long, and contain 100-1000 eggs.

Larvae: Small, mostly black caterpillars (~1/16 in long) will emerge in early May: exact timing depends upon climate conditions (~145-200 GDD). It is at this small size that the gypsy moth disperse by wind, until they land on a host tree where they begin to feed on foliage. Caterpillars will continue to feed and progress through 5-6 instars until they reach a final size up to 2.5 inches. Larger caterpillars can be identified by their hairy bodies and five pairs of blue dots and six pairs of red dots down their back.

Pupae: Around the third week of June, caterpillars will find a safe, protected location to pupate. Pupae are reddish brown and 0.75- 1 in. long. Pupation takes 10-15 days to complete.

Adult: Adult moths will emerge in mid-July. Female moths are larger (2-2.5 in.), white with brown chevron markings, and flightless. Male moths are smaller (1.5 in.) and light brown with dark brown chevron markings. Males will fly to females to mate and complete their lifecycle.

Gypsy Moth Impacts
Damage to trees and forests by gypsy moths primarily occurs through defoliation by the caterpillar life stage. Dense feeding populations can consume all the leaves on a tree, defoliating entire stands. The preferred host tree species are deciduous oaks, maple, birch, poplar, willow, apple, and hawthorn. Other, less preferred deciduous trees and even conifers, like white pine or eastern hemlock, will be attacked by gypsy moths when there are large outbreaks. Typically, a healthy deciduous tree can survive one complete defoliation event, because they have enough energy reserved to produce new foliage in the same growing season. However, multiple years of defoliation or additional stress can cause deciduous tree mortality. Conifers will die after only one heavy defoliation event.
Across Massachusetts, gypsy moth density can fluctuate greatly from year to year. Gypsy moths have cyclical periods of small persistent populations and large outbreaks. Population trends are primarily driven by climate conditions and the balance of natural predators and disease. Predation from small mammals, birds, and insects, as well as, parasitic infection from flies and wasps regulates small populations.

Under certain conditions, gypsy moths can be significantly impacted by disease. Nucleo-polyhedrosis virus (NPV) is a wilt disease that causes high mortality in caterpillars and pupa when populations have been maintained high density in an area. The introduced fungus Entomophaga maimaiga (EM) causes high mortality in during both periods of low and high density infestations, but requires specific moisture and temperature conditions to effectively spread and infect the caterpillars. EM has kept gypsy moth populations from reaching large outbreak stages since the late 1980’s. However, dry conditions in Massachusetts can lead to large outbreaks due to lack of EM fungal success.

There are several steps Massachusetts residents can take to protect their trees from mortality caused by gypsy moths. The first step in gypsy moth management is assessing and monitoring the population. Be aware of the caterpillars seen feeding in the spring, the presence and location of adult moths, and the abundance of egg masses.
The recommended insecticide treatment for gypsy moth is Bacillus thuringiensis spp. kurstaki (Btk) or other biological pesticides.
Applications should be done by licensed applicators with the specialized equipment required to completely coat a tree’s leaves. Btk should be applied directly to foliage soon after caterpillar emergence where it will be consumed during feeding. Btk is most effective in young caterpillars and will not be effective on large caterpillars. Treatments should typically be applied at 90-400 GDD. Often, by the time caterpillar feeding is noticeable on a tree, it is too late to treat. This is why it is important to check for egg masses before emergence and look for the small caterpillars in early May.
Many commonly recommended treatment options are not effective in decreasing gypsy moth population or minimizing damage to trees. These include burlap strips, duct tape bands, or moth traps.
If trees have been defoliated by gypsy moth, assess and monitor tree health and recovery. Trees may require additional watering, fertilizing, or mulching to promote refoliation. Avoid additional stressors, such as, mechanical or chemical damage or soil compaction.
Finally, an important effort in management is to minimize gypsy moth spread. Egg masses can be located on more than just trees; common locations include cars, trucks, storage and moving containers. Anytime after eggs are laid in August, check for hidden egg masses to avoid spreading gypsy moths. Viable egg masses will be firm to the touch and have no holes.

104th Annual Massachusetts Tree Wardens' and Foresters' Association Conference
By Rick Harper
On Tuesday, January 10 and Wednesday, January 11, 2017, the Massachusetts Tree Wardens’ and Foresters’ Association (MTWFA) hosted over 300 attendees and over 30 exhibitors at the Host Hotel in Sturbridge, MA. The two-day event featured a trade show floor filled with exhibitors displaying equipment, technology, and literature for sale and for give-away, and educational sessions with a roster of well-renowned speakers. In addition to the annual business meeting and informative lectures, the conference also featured door prizes, opportunities for networking, and a lunchtime awards ceremony.
Speakers on the first day included state specialists from the Massachusetts Department of Conservation and Recreation, Julie Coop and Jeff Enochs. Ms. Coop, the Urban and Community Forestry Program Coordinator, discussed community reforestation initiatives in Gateway Cities, the annual Arbor Day Poster Contest, new DCR factsheets, and gave some additional program updates. Mr. Enochs, a forester in the DCR Forest Health Program, provided an update on forest heath activities in the state, including results of the aerial surveys for defoliation in the state and the latest on gypsy moth, Asian longhorned beetle (ALB), emerald ash borer (EAB), southern pine beetle, winter moth, and the cynipid gall wasp on the Cape and Islands – invasive insects all currently present in Massachusetts and known to be detrimental to tree health. Included on the afternoon speaking roster was Michael Smith, Technical Training Specialist from Baystate Roads, University of Massachusetts Transportation Center. He discussed the importance of setting up a proper work zone that complies with regulations and statutes, and helps to keep traffic moving and workers safe.
Day one wrapped up with the keynote speaker for this year’s conference, Dr. Erika Svendsen, Research Scientist with the USDA Forest Service. Dr. Svendsen discussed findings from her research program and from other Forest Service scientists, pertaining to urban natural resource stewardship and how local greening initiatives can strengthen social trust, enhance civic participation, and foster innovation. She highlighted specific instances where community disturbance provided opportunities for residents, stakeholders, and decision-makers to come together in a spirit of resilience, building social capital, and fostering environmental stewardship.
On the second day, attendees learned how hurricanes and severe storm events can impact communities and urban forests, how to interpret forecasts and warnings, and where to get the latest forecast information from Glenn Field, Warning Coordination Meteorologist with the National Weather Service.
In 2016, the conference included a panel on Chapter 87, with attorney Julie Steiner, Professor of Law, Western New England University School of Law, and tree wardens from across the state. The panel was so successful, it was included again this year and Professor Steiner provided an overview of how and when to hold a tree hearing. Then Dave Hawkins, MTWFA board member and Tree Warden of Pelham, moderated a discussion with the audience and three panel members, Paul Sanborn, Tree Warden for the town of Andover, Marc Fournier, Deputy Director of Public Works, town of Andover, and Chris Courville, Tree Warden for the town of Princeton. There was a wide-ranging discussion of scenarios for when a hearing is required, who pays the advertising costs when a resident requests a healthy tree to be removed, whether a hearing is needed to transplant a tree, and many issues related to property lines.
Faculty and staff from the University of Massachusetts were also listed on the conference schedule over the two-day event. Dr. Nick Brazee, UMass Extension Pathologist and Plant Diagnostic Director, provided an update on woody plant diseases he saw in the lab in 2016. According to Dr. Brazee, many plants suffered the effects associated with the hot, dry conditions of 2016 and select diseases were noted like anthracnose on sycamore trees and rust on ornamental conifers and deciduous trees and shrubs. Tawny Simisky, the new Extension Entomologist provided an update on the insect pests and pressures that arose during the growing season of 2016. A number of scale insects and as many remember, gypsy moth, were prolific throughout Massachusetts this past spring, summer and fall. Rick Harper of the UMass Amherst Department of Environmental Conservation presented a UMass Urban Forestry program update.
The 2017 Seth H. Swift Tree Warden of the Year Award was presented to Chris Hayward, Tree Warden from the Town of Watertown. This award was created in 2000 to recognize individual tree wardens who exhibit notable leadership, dedication, and commitment to the profession. The individual must hold the position of Tree Warden in their municipality, their community must actively participate in the Arbor Day Foundation’s Tree City USA program and, among other criteria, the individual must demonstrate active leadership and dedication to the protection of urban trees, including outreach and education to community members. The recipient is presented with a sculpture of a silver, windswept tree and an announcement online and in the quarterly newsletter, The Bark. Congratulations, Chris!

Chestnut Oak, Quercus montana (syn Q. prinus)
By Mollie Freilicher, DCR Community Action Forester
Our species spotlight this month has the distinction of being the Society of Municipal Arborists (SMA) 2017 Urban Tree of the Year. Chestnut oak, (Quercus montana, syn. Q. prinus) also known as rock oak and rock chestnut oak, grows on rocky, upland sites and is native to the eastern United States, from southern Maine to Georgia, west to Mississippi, and north to Michigan and southern Ontario. In Massachusetts, it is found in every county except Barnstable and Dukes. Its common name, chestnut oak, comes from the likeness of the tree (and particularly the leaves) to American chestnut, its relative in the Fagaceae family. Chestnut oak grows in USDA hardiness zones four to eight.
Chestnut oak typically reaches 60 to 80 feet tall, with a 50 foot spread, and at maturity has a rounded and dense form. Leaves of chestnut oak are alternate, simple, ovate, about four to six inches long and about half as wide, with an acute or acuminate tip and a cuneate or rounded base. They are coarsely toothed, with obtuse teeth. Leaves are shiny and yellowish-green and fall color is yellow to reddish-brown. The bark of chestnut oak is distinctive, dark brown in color and with long deep furrows.
Twigs are shiny, hairless, and brown with gray lenticels. The buds are imbricate, slightly hairy, gray or reddish brown and ¼ to 3/8 inch long, resembling those of red oak (Q. rubra). Flowers are long catkins that appear in May, after the leaves have begun to emerge. Maturing the first year, the fruit is an acorn, about an inch long with a cap that can enclose up to half the fruit. The acorn is sweet and while crops are infrequent, black bears, squirrels, deer, and other wildlife enjoy the acorns. Historically, wood from chestnut oak was used for fuel and timber, and the bark, with its high tannin content, for tanning.
In its press release on the 2017 Urban Tree of the Year, the SMA notes that “[t]here’s growing interest in using chestnut oak in the urban environment because it is pH-adaptable, handles dry soils and periods of drought, has a beautiful mature form, requires minimal pruning, and tends to be free of major pests and diseases.” The forestry assistant for Dublin, OH, Jocylyn Kerr, nominated the tree. Of the tree, she says, “We started using chestnut oak in Dublin in 2009 as a street tree,” she says. “We have planted it to replace some of our ash trees as well as using it in greenspaces throughout the city. It has adapted well to the alkaline soils of Dublin and it seems to handle the salt well. The pyramidal shape is an added plus in its young age because it allows for our snowplows and garbage trucks to pass without destroying any branches.”
Going back a little further, in his 1846, A Report on the Trees and Shrubs Growing Naturally in the Forests of Massachusetts, G.B. Emerson notes that, “[t]his beautiful tree has many claims to attention,” and though he does not recommend it for use in the landscape, he recommends it for use on sites where nothing else will grow, for fuel, and for its sweet acorns. Lorin Dame and Henry Brooks, by contrast, in their 1901 book, Handbook of the Trees of New England, do recommend its use in the landscape, noting that “[i]ts vigorous, clean habit of growth and handsome foliage should give it a place in landscape gardening and street use.” They also note that it is occasionally available from nurseries, which propagate it from seed and that it is “more easily and safely transplanted than most oaks.”
Chestnut oak’s tolerance of drought, salt, and acidic or alkaline soil conditions recommends this tree for use in cities and towns. Though it may be challenging to find in nurseries, chestnut oak can make a great native addition to the urban forest, whether along a street or in a park or other large area.

Growing Greener—in Sheffield
In the Berkshires, the town of Sheffield is home to a dedicated group of individuals who make up the Sheffield Tree Project. The Sheffield Tree Project’s mission is “to work with the community to plant and care for a beautiful and diverse population of trees in the public areas of Shefﬁeld, Massachusetts, and to educate the public on the benefits of community forestry.” The Sheffield Tree Project operates under the umbrella of a local non-profit organization, the Sheffield Land Trust. The goal of the Sheffield Tree Project is to bring community members together and build civic pride through trees. They have planted more than 150 trees along the streets and in other locations in town. (Click here for a map of plantings.)
The group works in partnership with local nurseries, professional arborists and landscape contractors, and local community organizations. Funding for plantings has come from in-kind donations from local nurseries and tree companies, private donations, and Mass ReLeaf (now part of the DCR Urban and Community Forestry Challenge Grant.) They are also active in planning the town’s Arbor Day celebration and maintaining Sheffield’s status as a Tree City USA, one of four Tree City USA communities in Berkshire County. For Arbor Day in 2016, the Sheffield Tree Project, in conjunction with the Sheffield Land Trust, the Appalachian Trail Conservancy, the Appalachian Mountain Club, and the National Park Service planted trees as part of the restoration of the monument marking the site of the last battle of Shays’ Rebellion.

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.

Conditions as of January 17, 2017. Check out drought conditions in Massachusetts, New England, and the U.S. Almost all of Massachusetts is in drought, but the portion of the state in “extreme drought” is now 9%. (That is down from 36% the week of December 27, 2016.) The percentage of the state categorized as “severe drought” has also dropped from 59% the week of January 17, to 29% in the current report.

Rain as a Resource: St. Paul, MN Innovates Shared, Sustainable Stormwater Management
New infrastructure systems in St. Paul, MN use rain as a resource instead of letting stormwater enter area lakes and the Mississippi River, along with all of the pollutants that water collects. This new method of managing stormwater is called "shared, stacked green infrastructure," meaning the system does more than one thing on site, it can provide additional community services or amenities that add a sense of community.

Mapping the Urban Tree Canopy in Major Cities
By Feargus O'Sullivan
January 4, 2017—Which cities have the greenest streets? MIT’s Senseable City Lab is pushing toward an answer to this question with a new project called Treepedia. A map website that catalogues the density of the tree canopy in 10 global cities, Treepedia uses information from Google Street View to create what it calls the Green View Index—a rating that quantifies how green a street view looks according to the number of trees it contains.
Rating a huge number of street corners for the relative greenery of their appearance, Treepedia also allows browsers to click on a series of dots that reveal street view images of the location in question. The result is one of the most detailed catalogs of urban greenery available. Read the full story at Citylab.com.
The Old Oak: A Year in the Life of a Tree – photo essay
The seasons change, but the tree remains: Christopher Thomond has been photographing a single, 200-year-old Lancashire oak throughout 2016
By Christopher Thomond and Patrick Barkham
January 9, 2017—When Guardian photographer Chris Thomond volunteered to spend a year photographing a tree, he spent “a mad couple of weeks auditioning trees” – sending photos of them to his picture editors. “Many were an hour away from my home and we realised we needed something nearby. As I was driving along one day, 10 minutes from my house on the edge of Manchester, I saw a farmer repairing a fence and said, ‘You probably think I’m bonkers, but have you got any nice-looking trees?’ He was a bit wary but then he said, ‘I think I’ve got just the one. People are forever photographing it.’ It just went from there.” Check out the whole photo essay at The Guardian.
Boulder, CO's Repurposing of Emerald Ash Trees Also Gives Homeless New Hope
By Charlie Brennan
December 26, 2016—A pilot project by Boulder in which the recently homeless are put to work using wood from felled emerald ash trees for crafts projects — enabling them to hone skills preparing them for employment — is being called a success, several months after its launch. Billed as Tree Debris to Opportunity, the city earlier this month concluded its first session with clients from the Bridge House Ready to Work Program.
They mastered activities ranging from woodworking to laser printing and related computer applications, in converting trees lost to the invasive emerald ash borer into items such as cutting boards or intricate butterfly ornaments.
Margo Josephs supervised the program through her role as manager for community partnerships and outreach in Boulder's Parks and Recreation Department. She said three women and four men completed the first session, running from September to early December, with one more participant dropping out due to personal reasons.
"It's been pretty incredible for us to have gotten to know them and to see their transformation through this program," Josephs said. "They have all taken something different out of it, but it has all been impactful to their personal lives."
Boulder received a grant of $200,000 earlier this year to support the program on an 18-month pilot basis, the money coming as an award through the $5 million Knight Cities Challenge hosted by the Knight Foundation. The challenge is staged in 26 communities around the United States that were once home to newspapers owned by the brothers John S. and James L. Knight.Read the full story at dailycamera.com.
Chicopee, Holyoke to Create Urban Street Gardens to Reduce Stormwater
By Jeanette DeForge
January 25, 2017— Chicopee - The city is embarking on a new, innovative way to reduce the amount of untreated storm water and raw sewage that is dumped into the rivers in heavy rains and at the same time is hoping to make neighborhoods more attractive and greener. Instead of having rain water flow into storm drains, the city is hoping to create urban green areas along streets and in the yards of willing homeowners will be complete with trees to soak up the water instead of having it flow into storm drains and eventually into the Chicopee and Connecticut Rivers.

Northeast Warming More Rapidly Than Most of U.S.
By David Abel
January 13, 2017—New England is likely to experience significantly greater warming over the next decade, and beyond, than the rest of the planet, according to new findings by climate scientists at the University of Massachusetts Amherst.
The region’s temperatures are projected to rise by an average of 3.6 degrees Fahrenheit above pre-industrial levels by 2025, according to the study, published this week in PLOS One, a journal published by the Public Library of Science.
The scientists found that the Northeast is warming more rapidly than any other part of the country except Alaska — and that the 3.6 degree Fahrenheit rise in the region is likely to come two decades before the rest of the world gets to that point. Read the full story at the Boston Globe.
Yet Another Gypsy Moth Infestation Ahead for Massachusetts
By Maddie Kilgannon
January 22, 2017—Massachusetts experienced a near-biblical swarm of gypsy moth caterpillars last summer, as the voracious, finger-long, invasive pests devoured trees across more than 100,000 acres in large swaths of the state. Now, state environmental officials are predicting widespread defoliation from gypsy moths again in 2017. Foresters surveyed areas throughout the state and found egg masses, pointing to the likelihood of another moth-infested season ahead. Read the full story at the Boston Globe.
Why Some Places Need to Burn
By Bill Chaisson
January 4, 2017—After a few delays due to higher winds, The Trustees of Reservations burned part of Wasque on Nov. 14. Folks over 50 might remember television commercials that concluded with Smokey Bear pointing at viewers and saying in a deep voice, “Only you can prevent forest fires.” By now Americans are getting used to the idea — Vineyard residents are already used to it — that you have to burn some natural places in order to save them or make them work.

Tree-Bark Thickness Indicates Fire-Resistance in a Hotter Future
January 11, 2017— A new study has found that trees worldwide develop thicker bark when they live in fire-prone areas. The findings suggest that bark thickness could help predict which forests and savannas will survive a warmer climate in which wildfires are expected to increase in frequency.
Trees in regions where fire is common, such as savannas and the forests of western North America, tend to have thicker bark, while trees in tropical rainforests have thinner bark, researchers at Princeton University and collaborating institutions reported Jan. 9 in the journal Ecology Letters. Bark protects the inside of the trunk from overheating and is one of a handful of adaptations that trees use to survive fire. Read the full story at ScienceDaily.
