Eastern Box Turtle
(Terrapene carolina)
Ecoview
by Whit Gibbons
November, 1998
Ecological research is conducted everywhere
-- in swamps, on mountains, beneath the ocean. But one study supports the
idea that some fascinating biological behavior can be happening right in
our own backyards.

I. Lehr Brisbin of the University of
Georgia's Savannah River Ecology Laboratory tells it this way:
“The old saying
notwithstanding, familiarity does not always breed contempt. In at least
one case, public awareness of a wildlife study provides an opportunity to
spread into peoples’ daily lives a conservation message about a
potentially threatened species. The work involves using miniature radio
transmitters to study the movements and behavior of common box turtles
living in an established suburban neighborhood and an adjoining forest
park preserve, Hitchcock Woods of Aiken, South Carolina.

“Scarcely any youth growing up in the eastern United States has not at
one time or another brought one of these once common turtles home to become
a pet or been with someone who a stopped a car to help one of these hapless
creatures off the highway. Their seemingly blind lumbering across the road
in the path of oncoming traffic always caused me to wonder how they ever had
the smarts to survive for hundreds of years—since
the age of the dinosaurs!
“Recently, however, this well-known creature was placed on the federal
list of potentially threatened species. Clearly, more basic biological
information must be gathered to explain their alarming declines in numbers
in recent years.

“The capture and overseas
shipping of large numbers of box turtles as part of an ever-expanding pet
trade has certainly contributed to the decline. But impacts of the
ever-present threats posed by highway deaths and increasing expansion of
housing developments into their woodland habitats is not yet known. Age
can be determined in many turtles by counting growth rings on their
shells, and some turtles we find in suburban areas are older than the
housing developments in which they live. The use of backyards and
flowerbeds by turtles in such neighborhoods may actually represent their
determination to return to previously wooded habitats they frequented in
their youth.
“After a decade of study and around a thousand sightings of 21
neighborhood box turtles, certain findings began to emerge. We expected to
find that road kills were a common cause of death in turtles living in
these neighborhoods but, surprisingly, our radiotracking studies revealed
previously unsuspected threats might actually pose greater hazards to
turtles in suburban areas.

“For example, turtle-friendly home-owners accidentally killed some
turtles by burning piles of leaves and yard-rakings where turtles had hidden
themselves. Death beneath whirling blades of power mowers cutting overgrown
lawns and drowning in backyard goldfish pools with no climb-out ramps also
resulted in the unintended deaths of some radiotagged turtles.
“In contrast, some of the turtles appeared to be aware of the danger
inherent in crossing suburban streets. In one striking instance, a
particular turtle was observed to pace up and down a street curb for nearly
24 hours before making a decision to ‘race’ across the street in only 90
seconds!
“Such information has made both
scientists and homeowners living in these turtles’ neighborhoods acutely
aware of how complex the issues are that determine the life or death of
individual turtles and ultimately the survival of all box turtles in the
developed world.

“A powerful conservation message is
delivered on a very personal level to homeowners who share their
neighborhoods with turtles. We may become complacent about threats of the
survival of species such as pandas, gorillas and tigers living in distant
regions, but can we ignore or fail to be moved by the plight of a familiar
and well-known creature sharing our own backyard?
“In
addition, as a favorite subject of local science fair projects,
observations of the secret lives and complex behavior of these radiotagged
box turtles carry a unique conservation message to a new generation of
future suburban homeowners.
“The fate and ultimate survival of many
native wildlife species will ultimately depend on the compassion and
understanding of the younger generation. The neighborhood box turtle may
well become an important flagship for wildlife conservation concerns for
the 21st century.” |
