Massachusetts Emerald Ash Borer Quarantine


Information for Woodland Owners and Forest Professionals in Massachusetts on the Emerald Ash Borer


EAB News Feed

A state-wide Quarantine was put into effect on November 17, 2014 and will remain in place until rescinded or modified in writing by the Commissioner of the Department of Conservation and Recreation (DCR).

Reason for the Quarantine:
In 2012 an infestation of Emerald ash borer was identified in the town of Dalton, Berkshire County, Massachusetts. The Emerald ash borer (Agrilus planipennis) (EAB), a beetle native to Asia, is a destructive insect pest of all ash tree species (Fraxinus spp.). It attacks healthy ash trees, including the native white, green and brown ash. As documented in other states with infestations of EAB, this invasive species can cause widespread ash tree mortality, cause great economic and environmental damage, and requires measures to suppress, control and slow its spread in Massachusetts. Emerald ash borer has the potential of killing infested trees in 3-5 years. Spread of this invasive pest into the ash hardwood forests of the United States has already caused severe economic losses. DCR believes that the establishment of this Quarantine will slow the spread of the insect to other states.

  • Affected Area: The Quarantine applies to all public and private land in Massachusetts.

EAB Treatment Methods

No Person shall harvest, cut, move, carry, transport or ship (or authorize or allow any other Person to do the same) Regulated Articles outside of the Affected Area within Massachusetts during the Quarantine Period, unless specifically authorized in writing by the Commissioner of the Department of Conservation and Recreation or his agent.


2. What movement of Regulated Articles will DCR allow?

The requirements change somewhat during and after what is known as “flight season” for EAB.

Flight Season is May 1-September 30
Non-Flight Season is October 1- April 30

During non-flight season most regulated articles can be moved from the Quarantine area to non-quarantined areas with proper treatments or permits which travel with the regulated articles to and from facilities with compliance agreements. Contact DCR at 413-253-1798 extension 204 for assistance with the permits and compliance agreements or questions on the treatments available.

All parties transporting and handling these regulated materials (trucker, sawmill, dry kiln, etc.) must have the proper permit in their possession and must be traveling directly to and from a facility with a compliance agreement.


3. What movement of regulated articles is allowed to contiguous Quarantined Areas in an adjacent state?

As of May 1, 2013, all counties in New York State south of the New York Thruway including Rensselaer and Columbia counties are under Quarantine.
As of May 1, 2013 regulated articles (other than firewood) can flow unrestricted from Berkshire county into the two contiguous counties of New York.  New York State does not allow the import of any untreated firewood.  More on New York’s firewood regulations can found by clicking here.
