Description
The Wood Turtle is distinguished by a highly sculpted
carapace with the scutes raised in irregular pyramidal
shapes.
The carapace is tan to dark
brown in
colour with raised lines radiating from a corner of each scute. The plastron
is not hinged and is yellow with
a dark
blotch in the corner of each scute. The
head is black and may have faint yellow dots. The underside of the
neck, throat, tail and legs is yellow, orange or red. Adults reach
up to 24 cm carapace length.
Confusing Species
Wood Turtle are not easily confused with any other
species in Canada. Blanding's
Turtles
have a similar plastron
although it is hinged, but they lack the bright
colour of
the undersides and the sculpted carapace.
Spotted Turtles are similar in
colour of
both the carapace and body,
but they are
smaller and the carapace is
not sculpted.
Distribution
In Canada, Wood Turtles are found from Nova Scotia west
to southern Ontario. In the United States they are found in the
Great Lakes region and eastward as far south as Virginia.
Habitat
Wood Turtles, as the name implies, are our most
terrestrial turtle. Although they hibernate in water and nest near
the shores of rivers, they spend much of their time in upland
forests and meadows.
Reproduction
Individuals may take 18 or more years to reach
maturity. Nesting occurs in June and up to 18 eggs may be laid.
Some females may not breed every year. Nests are typically dug on
sandbars or river embankments. Hatchlings emerge from the nest in
fall at 3-4 cm in length. Predation rates on nests are as high as
90% in some populations. Unlike most turtles, the gender of Wood
Turtle hatchlings is independent of incubation temperature.
Natural history
Wood Turtles eat a wide variety of food including
leaves, fruits and flowers, mushrooms, insects, worms, and anything
else they can find. These turtles are considered to be extremely
intelligent. Many individuals learn to "stomp" for worms by
stamping their feet on the ground causing earthworms to come to the
surface. They are also reputed to be able to climb chain-link
fences and stairs. Individuals can live for 30 or more years.
Conservation Concerns
Because of their striking colouration and intelligence
these turtles are prized by the pet trade. Collecting for pets has
decimated many of their populations and it is now illegal to
collect them in most of their range. In Canada they are designated
Vulnerable by COSEWIC.
