West Penobscot Bay: Substantial coastal forest losses since early1990s: report

"Substantial deforestation" in all West Penobscot Bay towns between 1992 and 2011.  
Summary According to a report prepared earlier  August 17, 2015 for Friends of  Penobscot Bay, western bay towns Stockton Springs, Searsport, Belfast, Camden, Rockport, Rockland and South Thomaston lost about 30 square miles of forests between 1992 and 2011.

Full slideshow  as PDF and as powerpoint *** Listen to 8/17/15 presentation on this report

Twelve square miles of those lost forests became impervious surfaces, e.g. buildings, roads, parking lots. The remainder has become either wetlands or grasslands.  
Surprisingly with this 85% increase in developed land, came an average decline of 2% in west Penobscot Bay town populations.                                          
===============================

The report "Tools for Assessing and Managing Human Impact on Maine’s Harbors" was prepared by Kevin Frech, in cooperation with Public Laboratory

Funding for the study was provided  by the Azavea Foundationdedicated to improving data access and usage in natural resource and social applications
