Reducing Traffic Mortality
Traffic mortality is a significant threat to many species of turtles.
While closing roads adjacent to major wetlands may be the most desirable
option from an environmental perspective it is unlikely to occur in many locations.
Hence trying to reduce mortality is important.
The Canadian Amphibian and Reptile Conservation Network (CARCNET) undertook a
media campaign in the spring of 2002 to try and educate drivers about turtles on roads.
Many people would swerve recklessly to avoid hitting a dog or cat but think nothing of
running over just a reptile. Our goal was to attempt to raise the profile of turtles
and particularly to emphasize that many of the turtles people see on the road are females
looking for a place to nest. This makes running over a turtle a motherhood issue -
that's not just a turtle it's a mommy turtle.
A brief news article was written and a simple black and white graphic prepared.
The text and graphic were emailed to over 100 newspapers in the province of Ontario -
the province with the greatest diversity of turtle species and the
largest human population. It is unclear how many papers actually ran the material,
but we know at least a few did. In addition, reporters from some newspapers
called for more information so they could write a feature article.
We encourage others to make use of this material. The text of our press release
and the graphic are available below. Feel free to edit the text to fit your own
particular geographic area. We are grateful for financial support for this project
from the Mountain Equipment Co-op Environment Fund.
Press release:
Slow, Turtles!
Why did the turtle cross the road? To get to the other side.
It may seem silly, but it's the truth. Right now many turtles are
moving from one marsh to another, to find food, locate a mate or to lay eggs.
Historically this was no problem, but today turtles often must cross busy roads
on their wanderings. The result is that hundreds maybe even thousands of turtles
are killed every year.
"Traffic mortality is a serious issue for turtles," says Carolyn Seburn of
the Canadian Amphibian and Reptile Conservation Network. Ronald Brooks, a professor
of biology at the University of Guelph agrees. "My view is that these animals are not
going to survive if we don't prevent the roadkill problem."
There are many reasons why turtles are particularly vulnerable to traffic
mortality. First of all, many of the turtles seen trying to cross roads are females
looking for places to lay their eggs. Because turtles can live for decades,
killing pregnant females not only removes reproductive adults from the population
but it also removes all their potential future offspring. In addition,
surviving turtles can't lay extra eggs to compensate for increased mortality,
so once a population starts to decline
it is difficult to reverse the trend.
What can drivers do? "It's important to watch the road carefully when
you're driving," says Seburn, "particularly where the road comes near to wetlands
and rivers. Remember that turtles don't move very quickly and their first response
to danger is to pull into their shells. Turtles don't understand about cars,
but drivers can act responsibly and avoid hitting a turtle."
In many locations in Ontario drivers can also watch for turtle crossing
signs. These signs depicting a stylized turtle are the work of Turtle S.H.E.L.L.
(Safety, Habitat, Education, Long Life), a non-profit group dedicated to the
conservation of turtles. The signs have been posted at known crossing areas and
they alert drivers that turtles may be crossing the road.
The Canadian Amphibian and Reptile Conservation Network is a charitable
organization dedication to ensuring the survival of Canada's native amphibians
and reptiles. Recently it launched a major campaign to help reduce traffic
mortality in turtles. The Canadian Amphibian and Reptile Conservation Network
gratefully acknowledges the financial support of the Mountain Equipment Co-op
Environment Fund in accomplishing its goals. To find out more about turtles and
