Those areas that are inundated or saturated by surface water
or groundwater at a frequency and duration sufficient to support and
which under normal conditions do support a prevalence of vegetation
typically adapted for life in saturated soil conditions. Wetlands
generally include swamps, marshes, bogs and similar areas. For purposes
of regulation under this chapter, wetlands shall be construed to be
all areas meeting the definition of wetlands as then currently specified
by the United States Army Corps of Engineers and/or the Pennsylvania
Department of Environmental Protection. In any situation in which
these sources do not coincide, the more inclusive area shall be considered

Areas characterized by dense and extensive tree cover growing
closely together so that the driplines touch or overlap and in which
there is more than one viable tree of a diameter of six inches or
greater per 1,500 square feet of lot area. This definition also includes
groves of flowering or subcanopy trees, such as dogwood trees and
young forests where the immature branches may not yet be interlocking.
(To determine if an area has more than one viable tree of six inches
or greater caliper per 1,500 square feet, the total area of the land
in question, in square feet, shall be divided by 1,500. If the result
is equal to or less than the number of viable trees of a diameter
of six inches or greater and meets the other stated characteristics,
the area in question is considered a woodland.)
