particularly when the opportunity is presented to
incorporate such secondary corridors into urban
stormwater retention basins, associated drain-
ageways, and neighborhood parks.
As indicated in Table 59, secondary environmen-
tal corridors encompassed about 47,300 acres, or
3 percent of the total area of the Region, in 1985.
This included just over 900 acres of surface
water, about 20,400 acres of wetlands, about
13,100 acres of woodlands, about 12,200 acres of
other open lands, and just over 700 acres of

urban lands. As indicated in Table 60, the area
encompassed by secondary environmental corri-
dors did not change significantly between 1963
and 1985.
Isolated Natural Areas
In addition to the primary and secondary
environmental corridors, other, smaller pockets
of natural resource base elements exist within
the Region. These pockets are isolated from the
environmental corridors by urban development
or agricultural uses. Even though they are
