Natural Heritage Resources for Biodiversity Protection Planning

Natural Heritage LogoThe Natural Heritage & Endangered Species Program (NHESP) of the Massachusetts Division of Fisheries and Wildlife has many resources available to help municipalities, land trusts, watershed associations, and others with planning for biodiversity protection at the local or regional level.

BioMap and Living Waters Conservation Plans (2001 and 2003)
Town Core Habitat Reports (2004)

The BioMap and Living Waters Conservation Plans are important planning tools for protecting biodiversity in Massachusetts. They delineate Core Habitats, which are areas determined by NHESP to be most vital to the long-term survival of rare plants and animals and exemplary natural communities across the state. BioMap also shows Supporting Natural Landscape, which includes areas of undeveloped land, determined by GIS analysis which can buffer and connect Core Habitats, as well as provide habitat for common species and sufficient space for natural ecosystem functioning. Living Waters also shows the Critical Supporting Watershed for each Core Habitat, which identifies the more immediate portion of a Core Habitat's watershed where conservation efforts should be targeted.

BioMap and Living Waters information is available in several formats:

  • Town Core Habitat Reports are available for download. They summarize the rare species, natural communities, and freshwater habitats within the Core Habitats. The Core Habitat numbers in the reports are keyed to the numbers on large maps (available for purchase from NHESP) or on the interactive web map. In 2004, Town Core Habitat Maps and Reports were sent to Conservation Commissions, Planning Boards, Community Preservation Act committees, Community Development Plan committees, and town-based land trusts
  • GIS datalayers of Core Habitats, Supporting Natural Landscape, and Critical Supporting Watershed are available for download from Mass GIS.
  • BioMap and Living Waters summaries and presentations are available online.
  • Free Living Waters reports and posters, and free BioMap posters

Priority Habitats and Estimated Habitats, effective October 1, 2006

The revised GIS datalayer of Priority Habitats represents the geographic extent of Habitat of state-listed rare species in Massachusetts based on documented observations from the last 25 years. Priority Habitats are filing triggers for proponents, municipalities, and other stakeholders for determining whether a proposed project must be reviewed by the NHESP for compliance with the Massachusetts Endangered Species Act (MESA). Estimated Habitats are for use with the Wetlands Protection Act regulations (310 CMR 10.00). The revised Estimated Habitats datalayer contains polygons that are a subset of Priority Habitats. They do not include areas delineated for rare plants or for rare wildlife with strictly upland habitat requirements. These revised Priority Habitats and Estimated Habitats are the product of a statewide revision of Priority Habitat and Estimated Habitat boundaries to reflect the latest state-listed species data, understanding of species biology and habitat requirements, and GIS technology and data. For more information about endangered species review, please see the Regulatory Review section of the NHESP website.

Revised Priority Habitats and Estimated Habitats can also be viewed in:

  • Natural Heritage Atlas, 12th Edition - 187 pages of full-color, 11 x 17 maps covering the entire state, available for purchase from NHESP
  • Natural Heritage Atlas CD Viewer - statewide coverage of Priority Habitats and Estimated Habitats using the MassGIS Data Viewer software, available for purchase from NHESP
  • Interactive Web Viewer that zooms to a site and shows Priority Habitats and Estimated Habitats with color aerial photos
  • Large Priority Habitat and Estimated Habitat maps sent in September 2006 to the Conservation Commission and Planning Board of each town or city in Massachusetts

Note to conservation land managers:

There are important exemptions from review for projects or activities in Priority Habitat in the MESA regulations (321 CMR 10.14), including: The active management of State-listed Species habitat, including but not limited to mowing, cutting, burning, or pruning of vegetation, or removing exotic or invasive species, for the purpose of maintaining or enhancing the habitat for the benefit of rare species, provided that the management is carried out in accordance with a habitat management plan approved in writing by the Division.

Town Lists of Rare Species Occurrences, updated July 2006

For each town in the Commonwealth, the NHESP website lists all of the MESA-listed species that have been observed in that town. The species list also gives the most recent year of observation. These lists were last updated in July 2006 and will be updated on a regular basis. View town lists.

Massachusetts List of Endangered, Threatened and Special Concern Species and Rare Species Fact Sheets

The online version of the Massachusetts List of Endangered, Threatened and Special Concern Species contains links to rare species fact sheets that describe the habitat, life history, and distribution of that plant or animal.

NHESP Natural Communities, new September 2006

This new GIS datalayer contains the locations of natural communities of biodiversity conservation interest in Massachusetts. These locations are based on observation records maintained in the NHESP database. Program scientists classify and delineate natural community polygons by analyzing "on-the-ground" field data and available information about the landscape (particularly topographic maps and aerial photographs). For each polygon in the datalayer, there is a general description of the natural community type as well as a specific description of the particular natural community at the site.

The NHESP Natural Communities datalayer was released in September 2006 and is available from MassGIS. The datalayer contains 657 occurrences of natural communities, and an update of this information is planned within a year. Please view our Natural Community section for more information about natural community classification and fact sheets about several natural communities.

Certified Vernal Pools, updated September 2006
and Potential Vernal Pools (2000)

The GIS datalayer of vernal pools that have been certified by the NHESP was updated on MassGIS in January 2007, adding more than 600 pools to the data layer for a total of 4170 certified vernal pools statewide. This Certified Vernal Pool datalayer will be updated at regular intervals.

The GIS datalayer of Potential Vernal Pools is also available from Mass GIS. This is a datalayer of the locations of more than 29,000 potential, unverified, vernal pool habitats that were identified from aerial photographs. This survey represents a tremendous leap forward in the protection of vernal pools by providing the most complete picture available to date of the number and distribution of vernal pools across the Commonwealth. The statewide coverage of Potential Vernal Pools is also available in a standalone, CD Viewer format, which is available for purchase from NHESP.

Read our Vernal Pools section for more information about vernal pools and their certification. NHESP also sells a full color Field Guide to the Animals of Vernal Pools (2001) by Leo Kenney and Matthew Burne, which provides an excellent reference to the specialized creatures that depend upon vernal pools.
