Book Reivew: Branching Out: Features from the Past for the Future
By Rick Harper, UMass Department of Environmental Conservation

O’Brien, D.D. and G.W. Hudler. 2011. Branching Out: Features from the Past for the Future. Department of Plant Pathology and Plant-Microbe Biology, Cornell University. Ithaca, NY. 296 pp. Technical Publication-2012-001.

Intended for technical practitioners concerned with the management of ornamental trees and shrubs, including arborists, urban foresters, and green industry professionals, Branching Out: Features from the Past for the Future is a compilation of 18 years of feature articles appearing in the ever-popular newsletter produced by Cornell University, Branching Out: An Integrated Pest Management Newsletter for Trees and Shrubs. As an extensively-developed technical publication, this 296-page, spiral-bound resource is informative, enlightening, and practical. Through years of careful observation and experience, O’Brien and Hudler earned their positions as two of the foremost authorities on pest management in ornamental landscapes. This publication leverages their experience and perspective to help plant health care professionals manage existing pest-related outbreaks.

Laid out in a user-friendly manner with an easy-to-read-table of contents, this book quickly sets the tone behind the authors’ motives to create a resource that not only synthesizes  the feature articles from Branching Out, but also references further information in two internationally-renowned texts, also produced by Cornell University: Insects that Feed on Trees and Shrubs (2nd ed.) by W.T. Johnson and H.H. Lyon and Diseases of Trees and Shrubs (2nd ed.) by W.A. Sinclair, H.H. Lyon, and W.T. Johnson. A description of the 50ºF threshold as being the basis for Growing Degree Day (GDD) calculations is also outlined early in the text, as GDDs are generally considered a reliable environmental marker relative to pest development throughout the growing season. The authors also take the opportunity to let the reader know that pesticide recommendations that may normally be found in Branching Out articles have been removed, as pesticide labels and regulations may vary from state to state and even change.

The book is divided into three practical sections with further subdivisions: Insects (and other arthropods), Diseases, and Management.              

Insects are initially discussed under the heading “Host Specific Pests,” and some of the most well-known (and timely) insects are highlighted in this section, including emerald ash borer (Agrilus planipennis), birch leafminer (Fenusa pusilla), bronze birch borer (Agrilus anxius), hemlock woolly adelgid (Adelges tsugae), and viburnum leaf beetle (Pyrrhalta viburni). Pests under the “General Interest” heading include well-known actors like ambrosia beetles (Xylosandrus spp.), Asian longhorned beetle (Anaplophora glabripennis), black vine weevil (Otiorhynchus sulcatus), white pine weevil (Pissodes strobi), as well as sawflies, scales, and a well-known arthropod pest, spruce spider mite (Oligonchus ununguis).

“Host Specific Diseases” include beech bark disease (Nectria spp.), bleeding cankers on European beech (Phytophthora spp.) and horsechestnut (Pseudomonas sp.), oak wilt (Ceratocystis fagacearum), and thousand cankers (Geosmithia morbida).  “Diseases of General Interest” detailed include Armillaria root rot (Armillaria spp.), bacterial leaf scorch (Xylella fastidiosa), and a plethora of general canker diseases (e.g. Botryosphaeria spp., Eutypella spp., Nectria spp., Cytospora spp.), needle rusts (e.g. Coleosporium spp., Pucciniastrum spp., Uredinopsis spp., Milesina spp.), cedar rusts (Gymnosporangium spp.), and the much-talked-about generalist-pathogen, verticillium wilt (Verticillium dahliae). Of particular interest to commercial arborists and community foresters concerned with urban risk tree issues, this section closes with a list of “Top 8” wood decay fungi that features excellent color photos and succinct descriptions for easy identification.

The “Management” section of this compilation covers some little-discussed topics pertaining to ornamental landscape pest management, including the use of alternative insecticides, organic products, how to attract natural enemies, and the use of biocontrols, like nematodes. Of particular use to any reader would be the “commonly observed beneficial insects” write-up, which also includes 18 color photos of known beneficials, like the assassin bug (Family: Reduviidae), damsel bug (Family: Nabidae), flower fly (Family: Syrphidae), minute pirate bug (Family: Anthocoridae), lacewing (Family: Chrysopidae), spined soldier bug (Family: Pentatomidae), and others. This resource facilitates the quick ID of any of these insects that practitioners would naturally want to conserve and encourage on landscapes. Additionally, the section on insect traps details traps available for purchase and set-up. The inherent variability in ornamental landscapes may make trapping insects much more difficult than in traditional field crops settings or greenhouses that are more uniform in nature; practitioners should take note, however, that some clientele may be willing to pay for a pest trapping program to avoid a conventional pesticide application.

The final pages of the book are dedicated to miscellaneous plant health-related problems. Though these types of scenarios may not garner the “glam” and “fame” associated with insects or diseases of intrigue, they often comprise a majority of plant-related samples that a given diagnostic lab may receive. Thus, the book’s discussion of environmental stress, soil compaction, and site assessment by a renowned researcher like Dr. Nina Bassuk, make this guide all the more valuable and practical for the end user. Information about abiotic conditions like herbicide injury – with numerous high quality specimen photos – and discussion about plant-related problems that ensue as a result of drought conditions, as well as problems that result from improper mulching, are of great importance. Finally, any individuals who have interacted with plant or soil lab diagnosticians or who have been on the receiving end of the sample submission process can appreciate just how important, and even limiting, a sample can be if it is not properly taken, packaged for transport, and delivered in a timely manner. This book addresses this by clearly outlining how to produce high-quality photographs of insects and diseases to submit for diagnosis.

In summary, this extensive compilation represents an important step in addressing the key need of enabling practitioners to have an arms-length resource available that will help them formulate answers to important and sometimes complex questions, aiding them in making informed decisions about pest management strategies. Differing from traditional fact-sheets or white-papers, the diverse array of contributing authors that includes on-campus researchers and field-based extension specialists who are able to do more than simply illustrate pests and detail life cycles –have the freedom to develop the Integrated Pest Management (IPM) concepts that are the foundation of the management strategies of the many pests outlined in this book. In addition to formal research conclusions, the authors also identify their personal, experientially-based findings, and how these might contribute to potential pest management recommendations. This book is filled with high-quality photos with helpful captions, and titles depicting pests and plant-problem scenarios. Branching Out: Features from the Past for the Future would make an excellent addition to the library of any professional with urban or ornamental plant health care interests.

-----Species Spotlight-----
Pagoda dogwood, Cornus alternifolia*

By Mollie Freilicher, Community Action Forester

Pagoda dogwood, also known as alternate-leaf dogwood, is a member of the dogwood family, Cornaceae, and is native to Massachusetts. It ranges from Manitoba to Newfoundland, south to West Virginia (and along the Appalachians to northern Florida), and west to Arkansas and Minnesota. Where it occurs naturally, it prefers moist soils in the understory of mixed woodlands, along streams, and at forest edges. Unlike other members of the dogwood family, pagoda dogwood has alternate branching—hence the common name “alternate-leaf dogwood.” Pagoda dogwood is large shrub or small tree, reaching 15-25 feet tall, with a spread that is equal to, or greater than, its height. It is known for its spreading, horizontal habit. Hardy in USDA zones three to seven, pagoda dogwood is suitable for all parts of Massachusetts.

Leaves of pagoda dogwood are alternate, simple, and ovate, and can be two-to-five inches long and one-to-two-and-a-half inches wide. The leaves are clustered at the end of twigs, giving the tree a whorled appearance. There are five or six curved veins from the mid-vein, and the leaves are green above and paler below. In fall, the leaves can turn yellow to purple, but it is not usually notable.

Twigs are slender, shiny, and greenish, but can also be purplish or purple-brown. The flower buds are valvate, a quarter-inch long, red-purple in color, and hairless at the base and fuzzy toward the tip of the bud. Vegetative buds are also valvate, and smaller.

Pagoda dogwood flowers in late spring, with fragrant, white, four-petaled flowers that are borne in upright clusters at the ends of twigs. The fruit is a dark blue-black drupe, up to one-third inch across, that matures in September and October. The fruit stalk, which starts as green, turns to red, providing a nice contrast. The fruit provides food for small mammals and several species of songbirds.

In the planted landscape, pagoda dogwood is well suited for natural settings, massed plantings, borders, around utility lines, and also on its own as a specimen. Because of its horizontal, spreading habit, pagoda dogwood is often used for hedges and screening. It does best in moist, acidic, well-drained soils and will thrive in full sun or part shade. It is not tolerant of salt spray or drought and is susceptible to leaf spot and twig cankers. G. B. Emerson describes it as “A beautiful plant, with a great variety of character.” And Nathaniel Lord Britton in his 1908 tome, North American Trees, states, “The striking form, beautiful foliage, profusion of bloom, pretty red-stemmed, blue fruit, and autumnal coloration, make this a most desirable small tree in any situation.” Pagoda dogwood has much to offer in all seasons and would make a great native addition to the planting palette of communities in Massachusetts.

* Plants in the family Cornaceae have been reorganized and some plants, like pagoda dogwood, are now no longer in the genus Cornus and are in the genus Swida. We are using the “traditional” taxonomy here and using Cornus, but note that you may also see this plant as Swida alternifolia

Growing Greener--in Worcester

The City of Worcester was recently the subject of a project undertaken by the USDA Northeast Climate Hub to explore local adaptations to climate change. The project utilized a 360-degree camera to capture a few different areas and embeds information, resources, tools, and interviews into the experience. From the project: A changing climate poses risks for urban forests. Some forest pests may benefit from warmer temperatures, leading to tree damage and mortality. Heavy rain events and some types of storms may also increase in the coming decades, which can increase stormwater runoff, flooding, and tree breakage. Adaptation actions, such as tree species diversification and improved stormwater management can help reduce these risks. Explore the project here: https://www.climatehubs.oce.usda.gov/northeast/360/Worcester.

Oak Wilt in New York State
From New York Dept. of Environmental Conservation


Symptoms of oak wilt in white oak (A) and red oak (B)

What is oak wilt?
Oak wilt is a disease that affects oak trees. It is caused by Ceratocystis fagacearum, a fungus that develops in the xylem, the water-carrying cells of trees. All oaks are susceptible to the fungus, but the red oak group (with pointed leaf tips) often die much faster than white oaks (rounded leaf tips). Red oaks can take from a few weeks to six months to die and they spread the disease quickly. White oaks can take years to die and have a lower risk of spreading the disease.

Why is oak wilt a problem?
The oak wilt fungus blocks the flow of water and nutrients from the roots to the crown, causing the leaves to wilt and fall off, usually killing the tree. Red oaks (scarlet oak, pin oak, black oak, etc.) can die within a few weeks to six months, and the disease spreads quickly from tree to tree. White oaks (bur oak, scrub oak, etc.), however, often take years to die and the disease usually cannot spread to additional trees.

Where does it come from?
Oak wilt was first discovered in Wisconsin in 1944, but where it originated is still unknown. It has spread throughout the Midwest and Texas, killing tens of thousands of trees.

Where is it found in New York State?
In 2008, a small infection was discovered in Glenville, NY. It was quickly dealt with to prevent further spread. The disease resurfaced in the same location in 2013, and additional steps were taken to eradicate the infection. In 2016, oak wilt was discovered in Islip, Riverhead, and Southold in Suffolk County; Brooklyn in Kings County; and Canandaigua in Ontario County. 

How does it spread?
There are two main ways oak wilt is spread: 1) above-ground by beetles, and 2) belowground through tree roots.

Fungal spore mats form just under the bark of infected red oaks, after they have died from the disease. During the warmer months, these spore mats emit a sweet odor that attracts sap-feeding beetles and bark beetles, which can pick up fungal spores as they crawl around. The beetles are also highly attracted to fresh wounds in other trees, often caused by pruning. In this way, they spread the fungus from infected trees to healthy trees sometimes miles away. Infected firewood and other wood materials also pose a threat, because they can harbor the fungus and/or beetles that can spread the disease.

Spreading underground occurs when roots of nearby red oaks graft to each other (fuse together), creating a connection through which nutrients and the disease can move. In the Midwest, large blocks of red oak forests have died from the disease in a single season due to their vast network of interconnected roots. In contrast, white oaks are much less likely to create root grafts, and spore mats rarely form under their bark, significantly reducing the chance of spread from these trees.


Foliar symptoms of Ceratocystis fagacearum on black oak (Quercus velutina) showing bronzing starting at the leaf apices and lobes, and a localized area of green tissue around the base of the midrib. 

Symptoms
Symptoms of oak wilt infection are often very noticeable in red oak species, but aren't easily seen in white oaks.

  • Brown coloration develops on leaves starting at the outer edge and progressing inward toward the mid-vein of the leaf.
  • Branch dieback starts at the top of the tree's canopy and progresses downward.
  • Leaves suddenly wilt in the spring and summer and may fall while there is still some green on them.
  • Fungal spore mats may develop under the bark of infected trees.

What can I do?

  • Learn to recognize the symptoms of oak wilt, including leaf discoloration, branch dieback, and fungal spore mats.

· How to Identify, Prevent and Control Oak Wilt (PDF, 2 MB) - a US Forest Service publication

  • Avoid pruning or wounding oak trees in the spring and summer, when spore mats are present and beetles are the most active. If an oak wound occurs during spring or summer, it should be sealed immediately with wound dressing. This will slow wound recovery, but also deter beetles from landing on those areas - which will reduce the risk of oak wilt spreading.
  • Use qualified tree care professionals.
  • If you prune, learn how to do it properly (PDF, 380 KB).
  • Purchase and sell firewood locally. Try to avoid moving firewood more than 50 miles to help prevent the spread of forest pests and diseases.

Columnist Lilly Lombard: Celebrating shade trees in Northampton

By Lilly Lombard

April 23, 2017—Three years ago, driven by data showing a steady decline of Northampton’s public shade tree canopy, citizens lobbied the city to adopt a comprehensive municipal shade tree program to enhance our quality of life and strengthen our climate resilience. To kindle public interest in street trees, residents worked with the state’s community and urban forester, Mollie Freilicher, to conduct a highly visible, all-volunteer sample tree inventory.

Citizens also provided credible research to the mayor and City Council about why investing in shade trees as public infrastructure provides impressive financial, health, and ecological return. Finally, they shared as inspiration the example of Amherst’s successful tree program. The city of Northampton listened.

Flash forward to upcoming Arbor Day on Friday, April 28, and thanks to a supportive mayor and City Council, here’s our proud report. Foremost, Northampton has a permanent, qualified tree warden within the Department of Public Works, Richard Parasiliti, who partners with a skilled Public Shade Tree Commission to advance a plan to re-tree our walkable city.

Trees Have Their Own Songs
By Ed Yong

Just as birders can identify birds by their melodious calls, David George Haskell can distinguish trees by their sounds. The task is especially easy when it rains, as it so often does in the Ecuadorian rainforest. Depending on the shapes and sizes of their leaves, the different plants react to falling drops by producing “a splatter of metallic sparks” or “a low, clean, woody thump” or “a speed-typist’s clatter.” Every species has its own song. Train your ears (and abandon the distracting echoes of a plastic rain jacket) and you can carry out a botanical census through sound alone.

“I’ve taught ornithology to students for many years,” says Haskell, a natural history writer and professor of biology at Sewanee. “And I challenge my students: Okay, now that you’ve learned the songs of 100 birds, your task is to learn the sounds of 20 trees. Can you tell an oak from a maple by ear? I have them go out, pour their attention into their ears, and harvest sounds. It’s an almost meditative experience. And from that, you realize that trees sound different, and they have amazing sounds coming from them. Our unaided ears can hear how a maple tree changes its voice as a soft leaves of early spring change into the dying one of autumn.” Read the full story at The Atlantic.

 

On the Trail of New York's Greatest Trees
By Allison C. Meier


Camperdown elm, Prospect Park. Photo by Allison C. Meier

In 1967, an aging Marianne Moore wrote a poem to help save a Brooklyn tree. With a Pulitzer Prize and National Book Award to her name, the septuagenarian had attained an improbable height for a modernist poet: public popularity. Newspapers regularly pictured her in an anachronistic black cape and velvet tricorn hat; the following year she was even invited to throw out the opening pitch for the Yankees. So it was perhaps no surprise that when the recently-formed Friends of Prospect Park in Brooklyn noticed a rare camperdown elm near the Boathouse that was “a mere shell, hollow to the base, and further weakened by a great untreated wound,” they asked her for a poem.

Moore penned “The Camperdown Elm,” which appeared in the September 23, 1967 issue of the New Yorker. Its last line was a call to action: “We must save it. It is our crowning curio.” The camperdown campaign was a success, not just to patch the tree and prop up its eldritch limbs with crutches and cords, but to improve visibility for the deteriorated park around it. The elm was the first tree here that made me stop in my tracks, study the bends in its unique branches, and consider it as an individual. It was also my gateway into an ecological scavenger hunt of New York City, where almost every tree is seeded in a human story. Read the full story at CityLab.

Newton Works to Cut Unhealthy Trees and Replant
By Laura Lovett

Newton has always been known for its idyllic, tree-lined streets.

Nicknamed the “Garden City,” at its peak, Newton had close to 40,000 trees. That number has almost been halved, according to city officials, who say storms and poor health have caused trees to fall. But a recent initiative aims to take down the sickly, dangerous trees and plant their replacements. Between FY 2012 and FY 2014, 454 trees fell in Newton, causing scores of power outages and blocked roads. In October 2012, the memorable Halloween snowstorm caused 172 downed trees alone.

“Citizens were losing power for days on end and property was damaged,” said Mayor Setti Warren about the outages. After a storm in October 2014 where 16 trees were lost, the Warren administration decided to take action and evaluate the city’s tree policies. At the time the city had contractors come in and prune and deal with the downed trees. It cost the city approximately $200,000 a year for contractors, according to Chief Financial Officer Maureen Lemieux. So the Warren administration decided to hire a full-time tree crew to start addressing the tree issue. As of FY 2017, there are six full-time employees working on trees in Newton.

Growing Green: State to Plant 2,400 Trees in Brockton
By Marc Larocque

April 20, 2017– More maples, oaks, elms, and other types – such as serviceberry trees, dogwood trees, and flowering cherry trees – will soon be putting down their roots in Brockton. In the next three years, trees from a field of 40 different varieties of tree will sprout throughout an area stretching from downtown Brockton throughout the Campello district, according to state officials. The influx of arbor is being facilitated by the Greening the Gateway Cities Program, through the state Department of Conservation and Recreation. Read the full story at The Enterprise.
