In order to determine the conservation value of open space on
a specific parcel of land, the applicant shall prepare and the Planning
Board shall review a conservation plan of such parcel. The open space

or other natural resource value. Lands with conservation value include
scenic view corridors, agricultural land, including land with prime
farmland soils or soils of statewide importance, aquifers and their
recharge areas, ecological habitat for sensitive species, historic
buildings or landscapes, large areas or contiguous forest, ridgelines
and hillsides visible from public roads or other public areas, state
or federal wetlands, lakes, water bodies, and stream corridors. These
areas shall be mapped on a separate conservation plan which clearly
demarcates these areas.
