About the New England Landscape Design & History Association

The New England Landscape Design & History Association (NELDHA) is an independent, non-profit, tax-exempt organization.

NELDHA's mission is to further the education of landscape designers, historians, preservationists and conservationists, to promote their professions, and to communicate to the public NELDHA's commitment to landscape design, history, conservation, preservation, and stewardship of the land.

Our History

NELDHA originated as a student chapter of the Boston Society of Landscape Architects at Radcliffe College/Harvard University in Cambridge, Massachusetts, in 1968 and later as the Radcliffe Landscape Design and History Alumni Association. In 2003, the group incorporated as the New England Landscape Design and History Association (NELDHA), an IRC §501c(3) organization. Today NELDHA is a professional organization committed to the continuing education of its members as well as the public. NELDHA supports research in the fields of conservation, preservation and sustainable design practices. Today its membership includes a broad based group of landscape professionals, educators and others involved in design, history, preservation, design-build, plant-design, horticulture, students and government throughout New England.

Members combine professional careers with public service within their communities, and do pro-bono work for non-profit institutions throughout New England. Many of these initiatives are managed by the Community Outreach Group, (COG Design), which matches volunteer designers to community-based projects.
