An Emerald Ash Borer Information Session

Come to the Ewing Green Team’s February meeting to learn from the experts about the Emerald Ash Borer (EAB) threat, how it will affect your property, options for managing your ash trees, and potential solutions.

The Emerald Ash borer has been found in Ewing Township.  (See the Rutgers  EAB Rapid Ash Survey Report and Management Options, Prepared for the Township of Ewing, Mercer County , NJ, By The Rapid Ash Survey Team (RAST) October 2015.)  As this invasive pest can easily spread to neighboring trees, all residents should check their ash trees for symptoms of infestation.

“The emerald ash borer will kill 99 percent of all ash trees within the next few years,” said Bill Brash, the NJ State Certified Tree Expert with whom the EGT has been working about the EAB threat to the municipal tree canopy. “Residents should identify ash trees on their property and monitor for signs of damage or decline such as unusual woodpecker activity or missing bark.”

EAB Facts

eabinfosessionSince the discovery of emerald ash borer in Michigan in 2002, the beetle has killed hundreds of millions of ash trees in North America. In May 2014, the New Jersey Department of Agriculture confirmed New Jersey’s first detection of the emerald ash borer in Bridgewater in Somerset County, NJ.

The emerald ash borer is a small, metallic green, non-native invasive pest. Trees can be infested for years before the tree begins to show symptoms of infestation. Symptoms include canopy dieback, woodpecker activity, missing bark, D-shaped exit holes, shoots sprouting from the trunk, and S-shaped larval galleries under the bark.

Ash Tree Management

If a tree is already infested or in poor health, it may be best to remove the tree before it becomes infested and poses a hazard to people and surrounding structures. But for those residents with high-value ash in good health, trees can be treated before they become infested.

A Certified Tree Expert can help residents evaluate, then treat or remove ash trees. Contact the Board of Certified Tree Experts at 732-833-0325 or njtreeexperts@gmail.com for a list of professionals serving your area.

Report any signs. If any signs of the EAB beetle are found, call the New Jersey Department of Agriculture at 609-406-6939. Visit http://www.emeraldashborer.nj.gov for more information and check out our own EAB resource page.

It’s All About Trees…

Ewing Township Awarded $20,000 Sustainability Grant

The Ewing Green Team is delighted to report that we were just awarded a $20,000 Sustainable Jersey grant funded by the PSEG Foundation. Four $20,000 grants, eight $10,000 grants and twenty $2,000 grants were distributed to fund a variety of projects in communities around the state.  Our grant was for protecting the community tree cover.

Ewing’s existing natural resources, including our tree cover, and the need to preserve these resources were key priorities agreed to by Township residents during the Ewing Green Team’s 2014 Community Visioning Project. Residents agreed that preserving a community’s tree canopy, both forest stands and street trees, is extremely important in combating climate change, but also in creating a community that is aesthetically appealing and that provides opportunities for residents to be closer to nature.

emerald_ash_borerHowever, events of the past several years and upcoming threats to the tree canopy make protecting our tree canopy in Ewing a challenge. In 2012 Ewing suffered substantial losses to its tree canopy in its public parks as a result of a microburst in July, followed by Hurricane Sandy in October.  Since then, the Emerald Ash Borer (EAB), identified by a Rapid Ash Survey completed by the Rutgers Urban Forestry Program and NJ State Forestry Services in the summer of 2015, confirmed the presence of this destructive invasive insect in Ewing.  The Survey identified more than 890 infected ash trees on public property. To protect the integrity of the tree canopy, and to increase Ewing’s tree cover overall, the township must begin a management program to replace the trees with non-invasive and native trees.

Our grant, Partnering for the Restoration of the Community Forest: The 3P Plan, Partnerships-Plan-Planting,  will fund development of partnerships (the County, Rutgers, PSE&G, DEP, and however many others we can find) to manage the spread and removals of trees infected with the Emerald Ash Borer on Ewing municipal lands.  It also include partial replacement of Ash trees (100) lost to the EAB.   And, it will include community outreach and education.  We will be working with NJ State Certified Tree Expert, Bill Brash to manage the grant.

With the EAB infestations beginning to be detected in NJ, there is a need for a well thought out, researched, planned and implemented response to the threat.  Ewing will be demonstrating a leadership role in management of this issue as we intend our process to serve as a model for other communities to follow.

More News about our Tree Canopy

In addition, Ewing Twp. has also has negotiated with the Delaware River Joint Toll Bridge Commission for replacement of trees lost from the Scudder Falls Bridge Replacement project under the No Net Loss  Program(NNL).  The Twp. has been told that there will be funding for planting approximately 600 trees on municipal lands.  These will probably be planted in the fall.

We also hope to obtain grant funds to inventory Ewing parks for Ash tree locations and help the Twp. to determine locations for the 600+ NNL trees.

We are well on our way to accomplishing a number of the goals laid out by our Visioning, from tree plantings to restore our tree canopy, to sponsoring of educational workshops for the public, and more.
So, it’s a little good news for our tree canopy!  Thank you, Sustainable Jersey and PSE&G Foundation!

Sourwood – August Tree of the Month

by Ann Farnham, LLA

The tree favored this month by the Ewing Environmental Commission is Sourwood, Oxydendrum arboretum, one of America’s most beautiful native trees. It is at home in the eastern and southeastern United States in USDA Hardiness Zones 5-9. Ewing is located in USDA Zone 6b.

This specimen is located at a residence in the Mountain View neighborhood of Ewing. Sorrel Tree and Lily of the Valley Tree are two other names by which it is known.

Sourwood, a pyramidal, medium-sized deciduous tree (usually 25 to 30’ in height) with slightly drooping branches has glossy green leaves which turn brilliant scarlet in the fall.

Its bell-shaped, fragrant flowers appear in June through July in this area and are white pendulous clusters which persist for several weeks. Honeybees favor the flowers, from which they make a fine flavored honey.

Sourwood is unusual in that it gives us summer flowering as well as extraordinary fall color.

This fine tree prefers an acid, moist and well-drained soil. It will thrive in full sun or partial shade, although the fall color is best when the tree is located in full sun.

 Sourwood attracts few insects or diseases, none of which is serious.

The Ewing Environmental Commission welcomes suggestions for the Tree of the Month from all Ewing residents. Email suggestions or questions to lafarnham@verizon.net.

June Tree of the Month – Flowering Dogwood

by  Ann Farnham, LLA

Ewing Township’s Environmental Commission recognizes the beautiful Flowering Dogwood, Cornus Florida, as the Tree of the Month.

This lovely tree, a native to the eastern and central United States, is hardy from USDA zones 5-9 (Ewing is zone 6b), from Massachusetts to Florida and west to Texas.

Among the first trees to bloom in April or May, the Flowering Dogwood becomes covered in greenish-white, bloom-like bracts, four in number, which are usually 3-4” wide.  The bloom period lasts up to two weeks and is followed by clusters of red, berry-like, drupes which turn scarlet in September.  Birds love them.

These trees reach 20-30 feet in height, are beautiful in flower and have outstanding summer and fall foliage.  This species produces brilliant white flowers, but there are varieties ranging from pale pink to warm red.

Flowering Dogwoods do best in acid, well-drained soil, and partial shade, although they will tolerate full sun with appropriate care.  They are, unfortunately, subject to insect and disease problems.  In the Northeast the most widely recognized scourge is a fungus, Anthracnose, which is difficult to control and slowly kills the tree.  Fungicides may be effective.

Dr. Elwin Orton of Rutgers University has developed hybrids of Cornus Florida and Cornus kousa (Japanese dogwood), which are disease resistant and now commercially available.

Some straight species of Flowering Dogwoods which have shown resistance to Anthracnose have been selected and bred and are also now available at nurseries and garden centers.

May Tree of the Month

by Ann Farnham, LLA

The beautiful Saucer Magnolia, Magnolia soulangiana, blooms in Ewing in April and May.

This small tree or multistemmed large shrub is a hybrid and usually thrives in USDA Hardiness zones 4 – 9 (Ewing is USDA Hardiness Zone 6b). It is a cross between Magnolia denudata and Magnolia liliflora, reportedly a hybrid made by one of Napoleon’s retired cavalry officers, Étienne Soulange-Bodin, around 1820 in France.

In the garden it makes a beautiful focal point and is one of the first trees to bloom in the spring along with flowering cherries, redbuds, and the shrub, forsythia.

Saucer Magnolia blooms before its leaves appear in the spring but the flower buds are frequently damaged by frost as they open so early. Having a medium growth rate, a tree may reach a height of 20 to 30’ with a variable spread, pyramidal to rounded in form with low branches; it is also grown as a multi-stemmed shrub. There are dozens of varieties, each with a distinctive size and shape, with flowers which measure up to 4 to 8” across, and colors varying from purple-pink to white.

The best site for a Saucer Magnolia will have an acid, moist, porous and deep soil and full sun to partial shade. It tolerates wind and urban pollution fairly well. The roots need ample room to develop and the tree should be mulched to the drip-line (keep the mulch at least 6” from the trunk). If pruning is necessary, it should be done right after flowering.

There are several pests and diseases which attack Saucer Magnolia but fortunately they are infrequent. The Yellow-Bellied Sapsucker woodpeckers seem to favor its bark, and ring the tree with little holes, but the damage is slight.
