Because of the
decline of box turtles on Long Island, a field study was done in 2000
between May and November. The purpose was to determine
how turtles use space, habitats and if natural
and artificial barriers impede their movement. Previously, it was
thought that home range diameters for box turtles did not exceed
a few hundred feet.
Twenty box turtles were equipped
with small radio transmitters and were tracked almost daily by volunteers,
interns and staff. Often the researchers had to battle dense stands
of briar to make a daily visual sighting of all twenty turtles.
At each location, a variety of habitat and turtle characteristics
were recorded.
As all the information collected
is being analyzed, some interesting patterns are emerging. Some
turtles have one center of activity where most of their time is
spent. However, many turtles have multiple activity centers. Some
of the turtles have small home ranges of only ten acres but others
have large home ranges of over two hundred acres. Turtles cross
a variety of barriers in their movements including fire breaks,
streams, paved roads and even railroad tracks. The habits of the
box turtles change according to the seasons from grass to
shrub to forest.
