These maps illustrate land protection by various geographic units. Land protection data were drawn from the MassGIS Protected and Recreational Open Space datalayer through April 2013.

The Massachusetts Natural Heritage & Endangered Species Program and The Nature Conservancy's Massachusetts Program developed BioMap2 in 2010 as a conservation plan to protect the state's biodiversity.

BioMap2 Core Habitat identifies specific areas necessary to promote the long-term persistence of Species of Conservation Concern (those listed under the Massachusetts Endangered Species Act as well as additional species identified in the State Wildlife Action Plan), exemplary natural communities, and intact ecosystems.

BioMap2 Critical Natural Landscape was created to identify and prioritize intact landscapes in Massachusetts that are better able to support ecological processes and disturbance regimes, and a wide array of species and habitats over long time frames.

Resilient lands are areas that are likely to continue to function as wildlife habitat in a changing climate. These areas were identified with a customized Massachusetts version of The Nature Conservancy's resilience analysis developed in their Terrestrial Resilience project.
