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—in fact, over half of the total acreage of Priority Habitat is mapped for marine habitats of state-listed rare species.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 the Regulatory Review section of the NHESP website.See full metadata.Also available as a map service.

NHESP Priority Habitat and Estimated Habitat data layers within Dukes County are displayed in this interactive map. The NHESP is version 15, Effective 8/1/21. The latest parcel data for each town is included in the map. None of the data are survey-grade. The data and map are provided for general planning purposes only.The parcel data & NHESP data re provided by MassGIS -- NHESP Resources & Parcel Data

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 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.

These data layers represent diadromous fish passageways, impediments, habitat, species presence and sampling stations along coastal rivers and in lakes and ponds. The data layers include time-of-year recommendations to avoid impacts to present species and on restoration priorities and actions.The five layers were produced and will be maintained by the Division of Marine Fisheries (DMF):Restoration Projects - Restoration Projects refer to diadromous fish passage projects listed in the DMF Diadromous Fish Restoration Priority List.Sampling Stations - DMF maintains sampling stations in different coastal rivers to monitor the migrations and populations of river herring, American eel, American shad and rainbow smelt. This feature layer reports on the location and type of each sampling stations.Migratory Habitat - Migratory habitat refers to the presence of 10 species of diadromous fish in reaches of coastal rivers in Massachusetts.Rainbow Smelt Spawning Habitat - Rainbow smelt spawning habitat refers to specific locations in coastal rivers where rainbow smelt egg deposition was documented during their spring spawning runs.River Herring Spawning and Nursery Habitat - The ponds and lakes that have been identified by DMF as providing river herring spawning and nursery habitat, and those that river herring cannot access.More details...Map service also available.
