RBG Protecting Turtles in Cootes Paradise

Playing Mother Nature with the Blanding’s turtle

They don't move too fast, but they go pretty far.

And that's a big part of the reason why Blanding's turtles are in such peril in Cootes Paradise and other wetland areas of Royal Botanical Gardens property.

Females like to ramble long distances before laying eggs and that can get them run over by automobiles, scooped by kids looking for a pet, or facing other dangers.

Consequently, numbers of the reptile listed as threatened by the province have severely declined to a point that RBG biologists estimate there are only four or five in all of Cootes Paradise and maybe another 20 in the Grindstone Creek (Hendrie Valley) area.

Faced with the real prospect of losing the species from the area altogether, RBG workers have decided to play Mother Nature using radio telemetry and incubation.

This spring, they outfitted three reproductive Blanding's turtle females with radio transmitters and, after weeks of tracking, were able to locate two nests left by two of the mothers. One nest had 10 eggs and the other 13.

So they gathered up the 23 fragile eggs and put them in an incubator in the RBG Centre building to be carefully monitored over the next several weeks.

"We want to make the conditions ideal for them to hatch," says Kathryn Harrison, species at risk biologist with the RBG.

In the wild, she says, the eggs would have faced all kinds of hazards from cold weather, to trampling to being eaten by raccoons or foxes.

The eggs in the incubator should hatch in late August and early September. The RBG is hoping that, under these optimum conditions, all the eggs will hatch.

After a week, they'll be released back into the wilds of Cootes Paradise, with fingers crossed that a good number of them will survive accidents and predators and make it into adulthood.

"Life is tough for baby turtles," says Harrison. "They can find themselves in all kinds of problems."

Female turtles, she says, will need to live 15 to 25 years before they are capable of producing eggs, and that's the big goal of the effort to make the species sustainable into the future.

Asked why the RBG doesn't simply stock its marshes with Blanding's turtles raised in a laboratory, Harrison says, "the turtles we want to be in this area are turtles that are from this area."

It's far better, she says, to reproduce turtles "whose genetics have adapted for life in this area."

As well, she says, moving turtles from another area to here, could transport diseases with them.


The Blanding's turtle:

Is a medium-sized turtle (reaching up to 27 centimetres in length) with a bright yellow throat and chin. Different to other local turtles, with flatter shells, the Blanding's turtle has a more rounded dome shaped like an army helmet;

Lives in shallow water, usually in wetlands or shallow lakes with lots of water plants. They hibernate in mud at the bottom of water bodies from late October until the end of April;

• Is listed by the province as threatened, meaning it is "likely to become endangered if steps are not taken to address factors threatening it."

a vision for nature in Cootes

View the Eco-Park Document here Make Cootes national park, group urges TheSpec.com - Local - Make Cootes national park, group urges Create eco-park in urbanized area Eric McGuinness , The Hamilton Spectator (Jan 28, 2009) The idea of a Cootes Paradise National Park is being revived by local conservationists. But they say it is jeopardized by plans for a self-storage warehouse beside the Desjardins Canal at the east entrance to Dundas. They point to a new vision of an urban eco-park -- maybe a national park -- incorporating the Cootes marsh, drafted by Urban Strategies Inc., the firm responsible for McMaster University's campus master plan among other Hamilton projects. Joe Berridge, a partner who has helped reshape waterfronts in Toronto, New York and London, produced the concept document at the invitation of Ben Vanderbrug, retired general manager of the Hamilton Conservati

McMaster's Parking Problem: Next Level

I'm sharing a recent article published in the Dundas Star News about McMaster's plan to build a - get this - $17-million dollar parking structure. Seventeen million. Yes, $17,000,000.00 That's a lot of money to provide temporary shelter for vehicles of people who choose to drive to campus. We will be following this closely. Here's the article.  Cootes Drive six-storey McMaster University parking garage under review Variances or amendment to zoning bylaw expected to permit parking structure Craig Campbell, Dundas Star News, Friday, March 5, 2021 Zoning bylaw variances, or amendments, could be required for a planned six-storey, 567-space McMaster University parking garage west of Cootes Drive, and north of Thorndale Crescent. University spokesperson Michelle Donavon said the $17-million structure on parking lot K at Westaway Road will help ongoing efforts to re-naturalize parts of the west campus, by moving some surface parking into the structure. “These plans will increa

West Campus Eco-Art Project  A walking activity and site activation on McMaster’s West Campus.  West Campus Eco-Art Project is a project that incorporates creative walking activities and an artistic site activation connected with the West Campus Redesign Initiative at McMaster University. The initiative provides opportunities for connecting with nature through an on-line informational video, walking excursions and creative activities that deepen knowledge and experience with place in all its complexities (social history, citizen science, ecology and diversity).  Focusing on the Coldwater creek valley on McMaster’s West Campus, participants will learn about the history and unique features of the area and will be invited to then engage with the site through observation, sketching and stencil-making. Stencils will be used to paint text and image on the parking lot asphalt to delineate a blue line that marks an historic water route.  The project is supported by the McMaster Museum of Art (
