Previous Losing Ground Editions

In 1987, Mass Audubon’s Advocacy Department initiated the publication Losing Ground. The 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.

Losing Ground, Fourth Edition (published May 2009)

Beyond the Footprint showed a reversed trend of land development and conservation with 40 acres of open space being protected every day and the loss of 20 acres, but with development impacts outside of building footprints at 80 acres a day.
