Conservation Commission

Every city and town in the Commonwealth of Massachusetts has a Conservation Commission.
The duties and responsibilities of a Conservation Commission are spelled out in the Conservation Commission Act. The Conservation Commission is the official agency specifically charged with the protection of a community’s natural resources. The Commission also advises other municipal officials and boards on conservation issues that relate to their areas of responsibility.

Commissions’ Legislative Authority

In Massachusetts, Conservation Commissions’ authority comes from several sources: the Conservation Commission Act (MGL Chapter 40 section 8C) for open space protection; the Wetlands Protection Act (MGL Chapter 131 section 40) for protecting wetlands and waterways (Commissions have real power – they issue the permits); and the home rule provisions of the state constitution for non-zoning wetlands bylaws.

All state statutes can be found in the Massachusetts General Laws on the state web site at

General Information

Conservation Commissions are the local environmental agencies in  Massachusetts — responsible for protecting the land, water and biological resources of their communities.

Conservation Commissions are a group of volunteers who work long hours to achieve community conservation goals. Commissioners are appointed by their select boards or mayors. Through a special act of the Legislature one community has an elected Commission. The Commission often plays a supporting role in the choice of candidates.

Conservation Commissions have between three and seven members. The town meeting or city council sets the number. Terms are three years in length.

There are no state age, citizenship, residency, knowledge or experience requirements, though there may be local requirements. The tasks of a Commission require a great deal of study, learning and thought by its members who become expert only by patience and work. Appointments should not be made or taken lightly.

The overriding factors governing appointments should be a candidate’s interest in doing the conservation job needed by the town: open space and water resource protection. Since this goal requires a continual, firm commitment to conservation, persons who have no conflict of interest and who relate well to others should be selected. The Commission should represent a variety of interests, skills and backgrounds.

An engineer, a biologist, a naturalist and a lawyer may prove especially helpful. Knowledge of soils is useful. For purposes of coordination of efforts, well-qualified individuals who are members of other boards may be appointed to serve a term.

In addition to voting members, many Commissions also have associate members and committees on which interested citizens serve.

If you have an interest in serving on your local Commission, talk to the Commissioners and staff, attend meetings and hearings, and get a sense of what the job is all about. Volunteer to help. Let the Commission and the selectboard know of your interest.

The Job of Open Space Protection

The first powers given to Commissions in the Conservation Commission Act focused on “promotion and development of natural resources…and protection of watershed resources.” Under these powers Commissions undertake planning, acquiring and managing open space, and encouraging and monitoring conservation and agricultural preservation restrictions.

A Commission may accept gifts of money or land with the approval of the city council or selectboard, thus avoiding the delays associated with obtaining town meeting approval.

The Act authorizes Conservation Commissions to inventory the municipality’s natural resources and to prepare relevant maps and plans. Open Space and Recreation Plans are therefore coordinated by Commissions. These important documents are a prerequisite for securing Self-Help moneys for open space acquisition.

The Conservation Commission also has the authority to adopt rules and regulations for the use of conservation land. These regulations have the full force of law; they are not merely “guidelines.”

Today many Conservation Commissions spend the bulk of their time hearing and conditioning wetlands cases. While this responsibility is vital, it often leaves inadequate time for open space protection and other matters. To allow Commissions to carry out their regulatory responsibilities without losing sight of their original mandate, many Commissions have set up open space, land management and other committees involving those members (and associate members) most interested in the Commission’s original mandate.

The Job of Wetlands Protection

As the municipal focal point for environmental protection, Conservation Commissions were given responsibility in 1972 for administering the Wetlands Protection Act (G.L. Ch. 131 §40). Thus the Commission serves the community in a regulatory as well as a conservation capacity.

Under this law, Commissions across the state process over ten thousand applications every year for permits to do work in and near wetlands, flood plains, banks, riverfront areas, beaches and surface waters. The Wetlands Protection Act is described in detail in MACC’s Environmental Handbook for Massachusetts Conservation Commissioners. Over half of Massachusetts’ communities have adopted local non-zoning bylaws or ordinances giving Commissions further power to protect wetlands. The state’s highest court has approved the use of such municipal laws. These are administered by Conservation Commissions. If the bylaw/ordinance gives it the power, the Commission may also adopt regulations for its implementation.
