The Future
In its long history, the Blue Ridge area has changed
many times, and no doubt it will change many more. It has been barren
mountains, part of a broad plateau, and under the sea; and it has bulged
up again into a mighty range, only to wear down while trees covered its
slopes and life continued to evolve.
Even in the past 40 years, the Shenandoah landscape
has changed markedly. The many open fields and pastures have been
reclaimed by forest, forcing animal life to adjust accordingly. This has
diminished open-country animals such as red foxes, woodchucks,
bobwhites, and rabbits, and encouraged bears, pileated woodpeckers, and
other forest animals.

What changes can we expect in the next 40 years?
Within the park, probably there will be no changes as dramatic as those
experienced since the thirties. Trees will grow somewhat taller, and
many of the locusts, pines, sassafras, and other pioneers will give way
to the more shade-tolerant oaks, hickories, ashes, tulip trees, and
others. Ridgetop forests will remain stunted as the elements buffet
them, but trees in hollows will continue toward their giant potential.
Some forest creatures will probably increase. Woodpeckers, for instance,
will benefit as the aging forest produces more insect-infested wood. But
animal populations in general will probably decline somewhat as the
closing canopy shades out vegetation near the forest floor.
Taking a geological perspective, we can imagine all
sorts of possibilities. The Blue Ridge may erode to virtually nothing
and be covered again by water. Or it may be pressured upward into craggy
peaks. Perhaps there is a long chance that lava will once again flow
from great cracks in the rock. And changing climate may put entirely
different vegetative clothes on the land. A warming trend could once
again bring tropical forests, or cooling could bring glaciers from the
northperhaps this time to bury the Blue Ridge and wipe its
biological slate clean. And who knows what new forms of life will evolve
in response to the ever-changing environments?
But our concern and responsibility involve the next
few generations. What sort of Shenandoah and eastern seaboard will we
leave them? Will megalopolitan sprawl surround the Blue Ridge with
housing tracts, choke its air with pollutants, and fill every trail with
people? Or will we protect our environment, carefully channel our
development, and stop our population growth? Our choices may well
determine whether the natural drama of today will continue into the next
century and the next.
We will have to make some hard choices and sacrifices
to keep these: deer grazing at dusk in Big Meadows, clear water tumbling
over ancient gray boulders, a bear leading cubs through shadowy,
unbroken forest, a raven gliding high above the wilderness of
Shenandoah.
