- Why should we care about turtles?
All native animals are a necessary and useful part of the fauna (the
wild animals found in a particular habitat or territory). Turtles help control
plant life by incorporating it as part of their food source. They eat
invertebrate and vertebrate animals and are themselves food for fish, snakes,
birds and mammals. (Invertebrates are animals without backbones while
vertebrates are those with backbones. Invertebrates may be soft, such as
earthworms, or hard, such as crayfish, both of which turtles eat.) Turtles
also help clean lakes and rivers and play an important role in creating
balance within the ecosystem.
- Where do turtles live?
Turtles live wherever they can find the temperature, food and shelter
they need in wetlands such as bogs, fens, marshes, and swamps. Painted
turtles, for example, like shallow, weedy bays in lakes and slow-moving
rivers. There they find water plants and small soft-bodied animals to eat, and
they find basking sites or dense plant growth in which they can hide from
predators. Wood turtles like sandy, small rivers or ponds near fields and open
woods where they forage for berries, plants and invertebrates such as snails
and worms. Eastern Spiny Softshell turtles stick to open rivers and lakes with
shallow areas where they can hunt fish, crayfish and other aquatic food.

How
does the Government define species at risk?
Ontario status designations are the product of
complementary review and assessment processes implemented at national and
provincial levels. The national assessment process takes place under the
auspices of the Committee on the Status of Endangered Wildlife in Canada (COSEWIC),
and Ontario has been an active participant on COSEWIC since its inception in
1978. The provincial review process is implemented by the Ministry of Natural
Resources' Committee on the Status of Species at Risk in Ontario (COSSARO),
which includes non-OMNR representation. The purpose of this committee is to
ensure a uniform, science-based, defensible approach to provincial status
evaluations conducted for Ontario species.

(THR) |
A species that is at risk of
becoming endangered in Ontario if limiting factors are not reversed. |
|
Special Concern
(SC)
|
A species with characteristics
that make it sensitive to human activities or natural events.
|
|
Not at Risk
(NAR)
|
A species that has been
evaluated and found to be not at risk.

Which
turtles do we find on this list?
The designations
assigned to species on the following list are, in most cases, in agreement
with those assigned to the species by COSEWIC. However, OMNR has assigned
certain species a status designation that differs from the national
designation. For example, species whose Ontario status is of greater concern
than the status elsewhere in Canada have been assigned a higher designation by
OMNR. On the attached list, any exceptions to the national designation are
marked with an asterisk (*), and explanatory notes are provided.

Rationale:
These species are all multi-jurisdictional in range (i.e. they occur in
one or more Canadian provinces in addition to Ontario) and OMNR, based
primarily on COSSARO recommendations, recognizes the need to assign these
species a higher status provincially than has been assigned nationally.

Where
do turtles go in the winter?
Canadian
turtles hibernate for over five months every winter. Some, like the Painted
and Snapping Turtles, hibernate on the bottom of quiet backwaters, nestled up
to sunken logs or under stream or lakeside banks. Others, such as the Spotted
Turtle, hibernate in the fens or flooded fields in which they live during the
summertime. They must choose sites where the water does not freeze
right to the bottom or become too low in dissolved oxygen.
- Why do turtles bask in
summer time?
Turtles bask or lay in the sun
because they are reptiles and cannot make their own heat. The sun’s warmth
helps raise their body temperatures up to between 16° C and 35° C so they can
better digest their food. Also, their muscles work better if they are warm.
- Where in Canada are these species found?
Ontario has all eight species, Québec has seven, Nova Scotia four, New
Brunswick three, Manitoba and Saskatchewan two each and British Columbia and
Alberta one species each. There are no native turtles on Prince Edward Island
or Newfoundland.
- Do turtles have a good sense of smell?
Yes they do; they use their sense of smell to find and identify food, mates,
territory etc. On land turtles smell things the way we do but under water many
have special little bumps or barbels on their chins that contain olfactory
(sense of smell) nerve endings to help them find food in dark or muddy water.
Tiny Painted Turtles, for example, are born knowing that the smell of a
Snapping Turtle means danger and they react to fast movement by diving for
cover.
- Do turtles see well?
Yes, most species see very well. They even have color vision, particularly at
the red end of the light spectrum. They have the ability to detect small
differences in pattern and shape. This is very important for animals that live
at the water’s surface where it is possible to see for long distances. Their
ability to detect pattern and scent enables them to recognize their own
species and avoid enemies. Turtles only have binocular vision, meaning they
only see what is in front them.
- Do turtles hear well?
No, turtles lack a tympanum (ear drum) although they do have some of the
internal ear bones that other animals have. They can detect low frequency
sounds and pick up vibrations when on land or in the water, but turtles do not
depend upon hearing to any great extent.
- Is it true that turtles carry Salmonella?
Many animals, humans included, can carry Salmonella bacteria. Wild turtles can
carry the disease and also suffer from it. Perhaps ten percent in most areas
are carriers but this may be higher in very polluted waters. People should
wash their hands thoroughly after touching any animal. Very small children
(five years old or less) and the very old should not touch turtles. There are
many diseases that can be transmitted from animals to humans (the other way,
too!) and careful washing with soap and water is the best protection.
- Why do turtles cross
roads and highways?
Turtles of all ages will wander away from their home water bodies
occasionally, but mainly it is the adult females that must struggle overland
in the nesting season to find a suitable warm, sunny place to bury their eggs.
Roads border many of our rivers, ponds and lakes where turtles live, so
vehicles take a terrible annual toll on breeding females. Since turtles need a
specific combination of conditions to lay their eggs -- southern exposure with
its more direct sun, soft soil, the appropriate soil humidity, and little or
no plant cover -- they often have no choice but to go far from the water in
which they live. Female turtles may have used many of these sites for
generations.
- What do you do if you spot a turtle heading across the
road?
If you believe the animal to be in immediate danger and you wish to help, make
a safe stop. Help it across the road in the direction in which it was heading
or if it appears to be advancing toward more danger, take it to a nearby
suitable environment. A swampy area with a sandy bank behind it would be
ideal. If the turtle is obviously headed away from the water body in which it
lives, do not take it back to the water. It will only retrace its steps to get
to the nesting area.Smaller species such as Painted Turtles or Blanding’s
Turtles can simply be lifted and carried by hand or in a bucket or box. Be
aware that they have claws and do not put your fingers near their beaks --
they are frightened and might bite. Large Snapping Turtles are likely to bite
and scratch so they should be handled carefully and by adults or older
children only. Grasp the snapper at the base of the tail, lift it gently and
point the beak away from your body. Carry it to the edge of the road to
release it. If this method does not appeal to you try grabbing the tail and
sliding the turtle onto a large flat shovel or piece of cardboard and dragging
it to a safe release spot.
Important: On larger Snapping Turtles (over 30 cm/one foot in carapace
length), the weight may be sufficient to break the tail if the animal is
carried vertically. Use a shovel, plywood or cardboard and drag the animal. In
all cases be aware that the turtle’s claws are strong and the beak is sharp.
They can reach you if you are careless. Be prepared for frequent powerful
lunges of the head. ***
Do not try to lift a
large turtle by the tip of it's tail as shown here
- Is it true that the turtle's shell is hard
enough to withstand being run over by a vehicle?
No, the carapace (shell) is quite thin and easily crushed.
As shown in the following picture - Turtles suffer
fatal internal injuries when run over. (Graphic Content)
