Losing Ground 2020: Statistics
Town of Chelsea
Sixth Edition
Published February 2020, Losing Ground: Nature's Value In A Changing Climate reports on the pace and patterns of land development and land protection in Massachusetts between 2012 and 2017.
These statistics describe changes in land use between 2012 and 2017. Estimates of acres of land converted from a natural state to a developed state can be found here, as well as the rate of development in comparison to other areas. Natural land consists of forest, wetland, and water; open land consists of agricultural areas, bare soil, beaches, barrens, or low vegetation; development includes low density residential and commercial/industrial/high density residential development. Percentage calculations are based on the state's total land area, excluding major waterbodies.
Rank in relation to other towns/cities is indicated.
There are 351 towns/cities in Massachusetts.
There are 351 towns/cities in Massachusetts.

The level of protection for the area is summarized below. We also consider the proportion of important conservation resources that are protected in the area, including BioMap2 Core Habitat and Critical Natural Landscape, Green Infrastructure Network, and relatively climate change resilient land. Percentage calculations are based on the state's total land area, excluding major waterbodies.

Fifth Edition
Released in June 2014, Losing Ground: Planning for Resilience reports on the pace and patterns of land development and land protection in Massachusetts between 2005 and 2013.
