Description: The political boundary datalayer is a polygon representation of town boundaries created from arcs developed from survey coordinates extracted from the 68-volume Harbor and Lands Commission Town Boundary Atlas for the 351 communities (cities and towns) in Massachusetts. The Atlas was published in the early 1900's and is maintained by the Survey Section of Massachusetts Highway Department. For communities with a coastal boundary, MassGIS has collaborated with Massachusetts Water Resources Authority and the Department of Environmental Protection to complete a 1:12000 scale coastline. The boundary for the coastline was defined as being the upland side of tidal flats and rocky inter-tidal zones. Note that the 351 communities are the official municipal names, not including "villages" or other sections of towns.

Description: Estimated Habitats are for use with the Wetlands Protection Act regulations (310 CMR 10.00). The Estimated Habitats of Rare Wildlife datalayer contains polygons that are a subset of the Priority Habitats of Rare Species. They are based on occurrences of rare wetland wildlife observed within the last 25 years and documented in the NHESP database. They do not include those areas delineated as Priority Habitat for rare plants or for rare wildlife with strictly upland habitat requirements. The Estimated Habitats presented here are part of the 15th Edition of the Massachusetts Natural Heritage Atlas, and are effective beginning August 1, 2021.For projects or activities that fall within Estimated Habitats of Rare Wildlife and that require a Notice of Intent (NOI) to be filed under the Wetlands Protection Act, proponents are required to send a copy of the NOI to the Natural Heritage & Endangered Species Program (NHESP). Please note, the Notice of Intent form allows for a streamlined joint Massachusetts Endangered Species Act/Wetlands Protection Act review, and these filings will be reviewed by the NHESP within 30 days. Applicants choosing not to file jointly will be required by the NHESP to submit a separate MESA filing, which may take up to 90 days to review. For more information, please seewww.mass.gov/dfw/nhesp/regulatory-review.The Estimated Habitats of Rare Wildlife layer is stored in ArcSDE as ESTHAB_POLY.Estimated Habitats were extracted from the Priority Habitats of Rare Species datalayer, which was delineated by NHESP scientists from documented observations of rare species and are based on such factors as species movements and habitat requirements. The polygons were heads-up digitized in ArcGIS 10x and referenced to the MassGIS 2019 Aerial Imagery.Occurrence records are continually being added, updated, deleted or otherwise modified in the NHESP database. These changes are incorporated into the Estimated Habitats of Rare Wildlife datalayer every four years.Questions about the creation of this datalayer and its use should be directed to NHESP at 508-389-6360 or natural.heritage@state.ma.us.
Description: The Priority Habitats of Rare Species datalayer contains polygons representing the geographic extent of Habitat of state-listed rare species in Massachusetts based on observations documented within the last 25 years in the database of the Natural Heritage & Endangered Species Program (NHESP). Priority Habitat polygons are the filing trigger for project proponents, municipalities, and all others for determining whether or not a proposed project or activity must be reviewed by the NHESP for compliance with the (MESA) and its implementing regulations. Areas delineated as Priority Habitats can include wetlands, uplands, and marine habitats. The Priority Habitats presented here are part of the 15th Edition of the Massachusetts Natural Heritage Atlas, and are effective beginning August 1, 2021.If your project or activity falls within Priority Habitat and does not meet a MESA filing exemption (321 CMR 10.14), then you must file directly with the NHESP pursuant to MESA. For more information, please see www.mass.gov/dfw/nhesp/regulatory-review.The Priority Habitats of Rare Species datalayer is stored in ArcSDE as PRIHAB_POLY.Priority Habitats were digitized by NHESP scientists from documented observations of state-listed rare species and are based on such factors as reported species movements and known habitat requirements. The polygons were heads-up digitized in ArcGIS 10x and referenced to the MassGIS 2019 Aerial Imagery.Occurrence records are continually being added, updated, deleted or otherwise modified in the NHESP database. These changes are incorporated into revisions to the Priority Habitats of Rare Species datalayer every four years.Questions about the creation of this datalayer and its use should be directed to NHESP at 508-389-6360 or natural.heritage@state.ma.us.
