Maine has existing state quarantine rules (“quarantines”) related to emerald ash borer, hemlock woolly adelgid and European larch canker. These are in place to help slow the spread of damaging forest pests to new areas of the state and locations outside of Maine.

Because of recent detections of these organisms, revisions to department quarantine rules that expand those areas under quarantine are necessary. In all cases, these expansions will likely result in the regulated area crossing into additional counties. Quarantines impact the legal movement of regulated items. Regulated items are described in existing rule details below.

Before the formal rulemaking process begins, we seek input from all interested parties. Please join us in person or virtually on Thursday, February 16, to provide information on your perspectives on the rules.

If you move trees for planting or forest products with ash, hemlock or larch (tamarack) or hardwood firewood, rule changes may impact where those products can be moved and the handling needed to move those products legally. Rule changes may also affect the rate of spread of these organisms to new areas.

Once the formal rulemaking process begins, there will be a public comment period. Comments on the proposed rules must be submitted during that period.

For those who cannot attend the meeting in person or online, please send input to

IMPORTANT: Input at this session is not part of the formal rulemaking process. Any comments responding to the proposed rules must be submitted during the formal public comment period.
