MA Endangered Species Act (MESA) Regulatory Review

In order to protect rare species and their habitats we review projects & activities proposed within rare species habitat for potential impacts.

In light of current events, all non-essential state employees are working remotely. Electronic submittals, in addition to the required paper submittal, of Notices of Intent, MESA Project Review Checklists, Conservation and Management Permit applications, and Information Requests will now be requested. An electronic copy of the complete submittal (including all attachments) should be sent using a file share service to

Please ensure that the entire electronic submittal, including attachments and site plans, are accessible and legible and that the link to download the electronic submittal can be accessed by others (not just the direct recipient). Due to volume restrictions of the email system, please do not directly send the electronic submittal as a PDF. Please be prepared to provide copies of electronic submittals in an alternative format (such as reduced file sizes or zip files) if requested. The electronic copy may be sent in advance of or concurrent with the paper copy.

The thirty day regulatory review period will not begin until a complete paper copy of the submittal, including all attachments and the filing fee, is received by the Division. The paper copy must be mailed to:
1 Rabbit Hill Road, Westbrough, MA, 01581, Attention: Regulatory Review

A primary responsibility of ours is to review any proposed projects or activities you may have in rare species habitat (Estimated or Priority Habitat). This is to protect rare species and their habitats.

We will review your plans to determine whether the project will impact state-listed rare species and their habitats. This ensures that you are in compliance with the Massachusetts Endangered Species Act and the Wetlands Protection Act.
