LOCAL NOTE INJURED TURTLES: Outside of Peterborough the Ontario Turtle Conservation Centre has the following advice: “If you live outside of Peterborough, call us at 705-741-5000. We work with over 30 Turtle First Response Centres across Ontario – these are private clinics, or rehabilitators that we have trained in emergency treatment for turtles; the availability of these varies so please call us to arrange. We will be able to direct you to the appropriate one, while transfer to our hospital is being organized.”
In our local area contact the Rideau Valley Wildlife Sanctuary near North Gower (258-9480) who works with OTCC and sends all of the serious injuries there. The benefit of going to RVWS first is that they can provide fluids and pain meds to the turtle before sending it to OTCC which can take a day or more.
LOCAL NOTE AT RISK TURTLE NESTING: If you are aware of a turtle nest at risk, please see the following note from Canadian Wildlife Federation Biologist, David Seburn.”It is turtle nesting season! We are collecting Snapping and Blanding’s Turtle eggs from roadside nests to incubate them and then release the hatchlings back into the wild. Roadside nests can’t be caged and without protection most of turtle nests get predated by Raccoons. If you see nesting Snappers or Blanding’s Turtles please email me the location and we will try and collect the eggs (davids at cwf-fcf.org). We are only permitted to collect nests from Ontario and are working in Ottawa, Lanark, and Leeds & Grenville Counties.”

June is here. The nesting turtles are back! March is for maple syrup, in April it’s goodbye to the melting ice, in May the leaves come out, and in June it’s turtle time!
Every one of these annual events reminds us where we live; the previous statement could not be made in Paris or Los Angeles. Of course, if you are a high rise building dweller who rarely ventures outside the big city, you may not appreciate my point. Here in Lanark County, every June, many turtles crawl out of their ponds and streams and start crossing the highways looking for nesting sites. Elsewhere tourists might pay a fortune, say, to travel to South Africa for lions, or British Columbia or Quebec for whales, but here the wildlife comes to visit us!

Most of the time turtles are rather secretive – hibernating nearly half the year on the bottom of lakes and pond. Much of the rest of the year they swim around looking for dead things to eat and occasionally taking a break to warm up in the sun stretched out on a log. Overall, turtles are harmless, and in fact do some good since they are efficient scavengers that clean up dead animals from our water supply. All of our turtles – even the large snapping turtle – are opportunist feeders. They eat whatever they can conveniently find, which is mainly insects and dead fish. Biologists have spent many years studying turtle diets –by counting the items in their stomachs – and have this well-documented. Even large snapping turtles, which get blamed for eating ducks or game fish, rarely have any of these items in their stomachs. They too eat carrion. Yes, snapping turtles will snap at you — when on land — particularly if you let your dog frighten them, or if you poke them with a stick. Many people would do the same.
Let me mention, too, that every part of the world has its own set of turtles. If you were lost, and someone gave you a list of local turtles, you could pin down almost exactly where you were. North America has just over 50 species in all. Some places, like the west coast, are impoverished, having just one species. Other places, like Louisiana, are blessed with turtles – more than 30 species. Lanark County, has exactly, five. In approximate order of size, beginning with the smallest, they are musk turtle (or stinkpot), painted turtle, map turtle, Blanding’s turtle and snapping turtle. All but the painted turtle are now considered species at risk – that is, they are declining. Two, the musk turtle and the Blanding’s turtle, are officially considered threatened species. The decline has two main causes, (1) death on roads and (2) destruction of wild places.
NESTING IS A DANGEROUS TIME!
So, for about 50 weeks out of each year, turtles are rather quiet, inoffensive neighbours, who pretty much keep to themselves. In this way, they might set a good example for human neighbors, like the ones with the loud stereos and motorbikes … but I digress, I was asked to write about turtles. My point is that, finally, after 50 weeks of peace, all hell breaks loose in mid June! All the females of reproductive age climb out of the water and begin the laborious task of hiking around to find a nesting site. It is probably terrifying for them to leave the familiar water and venture onto land, but the nesting urge is too strong to resist. Once they find just the right location, they dig a hole, bury their eggs, and leave. That is the end of motherly care. The eggs are heated by the summer sun, and then, in September, baby turtles about half the size of walnut dig their way up to the surface and somehow find their way back to water.
This means that without fail, near the middle of each June, we are treated to a parade of female turtles, wandering around our roads and properties, trying to nest. They have been doing this for about 200 million years, more or less. Turtles existed before the dinosaurs, and they even survived whatever it was – an asteroid collision? – that eliminated the dinosaurs. Despite their long history, turtles just have not had time to learn to adapt to two new things: cars and roads. That tiny brain has no idea that a road means danger. And so, increasingly, we are losing our turtles as the reproductive females (and often the eggs they contain) are killed on highways.
Biologists have calculated how important certain types of individuals are to their species survival, i.e. their “reproductive value”. New baby turtles have low reproductive value because only a few ever survive –skunks, raccoons, crows, fish and even bullfrogs eat them. This high mortality rate for babies is natural for turtles. However the reproductive value of the adult female turtle is extremely high. Once she has made it to 20 years old she has the capacity to make up for the high mortality rate of the babies by laying from 10 to 30 eggs every year for decades. The turtles being killed on our roads are usually the adult females — with the highest reproductive value. When a female is killed – it means the loss of hundreds of offspring she might have produced over future summers. These loses cannot be replaced. As a result, turtles that were present in my childhood, like musk turtles and Blanding’s turtles, are now uncommon. Not only do turtles just cross roads, they are actually attracted to roads. The warm sand and gravel along the road side makes a perfect nest site. So turtles will come long distances to climb onto the shoulder and lay their eggs. If drivers are careless, the highway becomes a ribbon of death.
SO WHAT CAN WE DO?
1. The first is to accept and even appreciate this annual event. Just as the maple syrup flows in March, so do turtles flow across our roads in June. We might even build an annual tourist event around the nesting week. We could put up some highway crossing signs at critical locations, or better still, plan ahead and build small underpasses when roads are being reconstructed. And, of course, we have to protect critical nesting areas from subdivisions. More urgently there is the immediate issue of death on the roads.
2. Drive carefully. Turtles are slow-movers, so it really does take a [completely irresponsible driver] . . . to hit one with a car.
CAUTION PLEASE: Crossing the road! In June, Lanark County turtles cross the roads to look for nesting sites. The three species most often seen are the painted turtle (left), Blanding’s turtle (middle), and snapping turtle (right). Please, drive carefully, and let them nest in peace.

–Help them out. Stop, and carry the turtle the rest of the way across the road – in the direction she was headed, of course. Yes, some will not appreciate your help, and might try to scratch or bite, so keep a pair of gardening gloves handy and perhaps a shovel to help lift. A big snapping turtle is heavy, so I would recommend extreme care – probably best to simply act like a shepherd.
– Alert other drivers. Yes, you can stop your car and let other people know that a turtle is crossing the road. Not a good idea at 100 kilometers per hour, perhaps, but certainly feasible on many side roads.
–Let them nest in peace. If one arrives in your yard, keep the pets away, and let the children watch quietly from a respectful distance more than ten feet away. Think about the respect we give to pregnant women, and give the pregnant turtle the same courtesy. If she does nest, you can put a piece of chicken wire (not mosquito netting – that will trap the baby turtles in the fall) over the nest. Then, wait. Given the right amount of sun and rain, baby turtles should emerge in September.
One of the joys of living here is the annual spectacle of the June turtles. If you still think you must drive so fast that you ignore the crossing turtles, may I respectfully suggest you consider moving to downtown Phoenix or Las Vegas or Toronto, or one of our other larger urban centers, where you won’t have to be inconvenienced by other living creatures. Learning to share the landscape with wild animals is part of what it means to live here. We might start with courtesy to turtles, and then extend it to frogs, birds, butterflies, bears and all the other animals that lived here long before our ancestors decided to settle in North America.
Not everyone can personally save a blue whale, or a black rhinoceros, but everyone can drive responsibly, and, like a good boy scout, help the occasional turtle across the road.
