Emerald Ash Borer (EAB) Confirmed in Cambridge

Ash treeEmerald Ash BorerAug 23, 2018 – On Monday, August 20, 2018, the Department of Conservation and Recreation (DCR) confirmed that Emerald Ash Borer (EAB) has been found in Cambridge. EAB is particularly concerning because of the speed at which it kills Ash trees, generally within 1-3 years. Standing dead ash trees present a public safety risk due to how quickly their brittle branches will fail.

The City of Cambridge was the first municipality in New England to develop a comprehensive treatment strategy to protect the ash tree population on city property. Healthy Ash trees on city property, including street trees, have been protected from EAB through proactive treatments of TreeAzin over the past 3 years. TreeAzin is a product derived from seed extracts of the Neem tree and is administered by injection at the trunk of the tree. TreeAzin is listed by the Organic Materials Review Institute (OMRI) for use in organic production in the U.S. This pesticide is not hazardous to humans or animals. For more information on the City’s treatment program for EAB, please visit: www.cambridgema.gov/EAB

How do I know if I have an Ash tree?
According to University of Connecticut College of Agriculture, Health and Natural Resources Tree Guide, Ash trees have four identifying features:

  1. Ash trees have compound leaves comprised of 7 to 11 leaflets.
  2. The twigs are smooth, rigid and grayish and resemble bones.
  3. The bark of mature trees is deeply furrowed.
  4. They have opposing branches.

I have an Ash tree. What do I do?
If you have an ash tree on your property, please consider one of the following:

  • Treat – If you have not yet begun a treatment program, we recommend that you work with a certified arborist to develop an ongoing treatment plan for your Ash tree. It is far more cost-effective to treat a healthy Ash tree than it is to remove it. You can find a certified arborist at www.massarbor.org.
  • Remove – Dead and dying trees become a risk for public safety. Remove and replace unhealthy Ash trees with different species. Doing nothing may put you and your property at unnecessary risk.
