Our Ontario turtles are semi-aquatic; while they spend a lot of time in the water, they also travel on land a lot too.  They will be on the move any time from April to October, although the busiest time for them is May and June.  Both males and females travel, and both are equally vulnerable to road mortality (the OTCC consistently sees 50:50 males to females in all species except the map turtle).

Females travel the most in June, as this is their most important time for laying eggs.  They look for appropriate sites to lay their eggs, and often travel large distances to find them.  Each species has their own preference and preferred time for laying eggs.  Laying eggs involves the female digging a hole (very slowly, in true turtle style!) and depositing the eggs, and then covering them up. There is no parental care of the eggs beyond this, and the hatchlings are on their own to find their way to water. Unfortunately, they don’t always choose the best site…

Snapping turtle nesting on the roadside

Blanding’s turtle laying eggs

Turtle eggs act as food for a great many wild species, and only a very small percent (less than 1%) ever make into the population.  In fact, it takes about 59 years for a snapping turtle to have a hope of replacing itself in the population, since they mature so late, and so few eggs survive!

While populations can sustain this loss of eggs and hatchlings when no other unnatural threats are placed on them, all of our Ontario species are now considered Species at Risk, due to the many human-related threats.  As a result, they need all the help they can get to attempt to offset this.  Many conservation initiatives are underway across the province, to help tip the balance back and allow populations to survive.

While protection of the adults is obviously the most important conservation initiative, additional programs also can help to augment populations.

Nest Protection

Nest protection programs are underway by biologists across the province, to increase the survival of the eggs, and hatchlings.  It is not legal to disturb or interfere with a natural nest in any way, without the appropriate permits through the Ministry of Natural Resources and Forestry (MNRF).  However, the MNRF does allow nest protection on private property, carried out by the property owner.

If property owners decide to do this, it is very important that no harm is done in the process- eggs and hatchlings can be put under even more risk, with improper nest protection devices.

Since most of our Ontario species of turtles have  “temperature dependent sex determination” i.e. the temperature of incubation affects the sex of the turtles, it is very important that the temperature of the nest is not interfered with, by materials that shade the site.

If you’re not a DIY person, OTCC sells these nest protectors. Call us at 705-741-5000 to place your order.

For those who are a bit handy:

You can make a nest protector using a wood frame with narrow-gage mesh (sometimes called carpenter’s cloth), staked securely into the ground.

IT IS VERY IMPORTANT THAT THERE ARE ESCAPE ROUTES CUT OUT OF THE FRAME. Without these, the hatchlings have no means to escape after hatching, and can quickly die.

1. A wooden frame is made and covered with wire mesh.

2. The escape routes cut into the wooden frame must be big enough for the turtles to leave once hatched.

3. Stake the device as shown to prevent movement of the nest cage by a predator. Make sure the stakes do not disturb the nest itself!

Remember: Do NOT dig up the nest if you do not see signs of hatchlings emerging. Many clutches hatch and the hatchlings remain in the nest over the winter, and only emerge in the spring!
