Over the past 50 years, the landscape of Massachusetts has been transformed by new residential and commercial development. Eastern and southeastern Massachusetts have undergone the most change, but virtually every community in the Commonwealth has experienced rapid growth driven by economic and demographic factors.
Since 1991, Mass Audubon has been using the most up-to-date technology and methods available to analyze changes to land use patterns in Massachusetts every five years. The results are published in our Losing Ground report series, providing conservationists, town planners, and agencies with information for planning and advocacy.
The sixth edition of our report, Losing Ground: Nature's Value in a Changing Climate, focuses on the pace and patterns of land development and land protection in Massachusetts between 2012 and 2017. It comes at a time when the effects of climate change are becoming increasingly evident across the Commonwealth—and around the world—and the value of undeveloped land has become even more crucial to reducing greenhouse gas emissions and providing resilience in the face of growing environmental threats.

Since the first edition was published in 1987, the Losing Ground series has resulted in increased state funding for open space conservation and a reversal of trends in open space protection and land development in Massachusetts. The conclusions of the reports have become the data of record in state administration, legislative, media, and land trust community citations. Explore previous editions of the report >
