This preliminary landscape plan for Magazine Beach was discussed last year at a Cambridgeport Neighborhood Association meeting.

Cambridge’s Magazine Beach Park is featured in an exhibit opening Monday at the State House, as well as in a March 16 panel discussion there on “Effective Partnerships between Government and Community Groups” in which the Cambridgeport Neighborhood Association and two other community groups will present case studies of how they have partnered to protect and preserve green open spaces.

The free lunchtime panel with legislators and state conservation officials looks at improvements made to the 15-acre Charles River park’s historic Powder Magazine house and western portion through a partnership between the association and state Department of Conservation and Recreation.

Other examples of partnerships are the Friends of the Upton State Forest’s work with state, city, the nonprofit Preservation Massachusetts and forest user groups to preserve the last remaining Civilian Conservation Corps camp in the state; and in the Southeastern Massachusetts Coastal Pine Barrens, where the Pine Barrens Partnership is linking with municipal, state and federal agencies, Native American tribes, environmental organizations and businesses to conserve a 100,000-acre region covering 26 towns.

The association recommends coming early to pass through security and see the exhibit, “Magazine Beach: A Place Apart,” which focuses on the Cambridge park but explores broader questions about how decisions are made about the use of public land. The exhibit is up through March 18.

The free panel discussion, with refreshments, is at noon March 16 in Room 350, on the third floor of the State House, 24 Beacon St., Boston, and the exhibit is on the fourth floor, across from the House chambers.
