Critters in the Creek – May 2, 2020 (11am – 3pm)

Have you ever wondered what lives in the streams and ponds of the Alton Grange? Would you like to learn more about the hidden biodiversity living in the streams and ponds of Caledon that we rarely see? Then join us on May 2nd, 2020 (11 – 3) to get a chance to see and learn more about the insects and invertebrates that live in the aquatic environments in the Alton Grange!

This event will be led by a team of scientists from the University of Toronto Mississauga who will share their knowledge of these animals with children and adults alike. We will have some animals ready to be looked at and examined more closely as well as guides to common aquatic animals if you want to try identifying them yourself or with a little help from the scientists. If the water is warm enough, children accompanied by their parents will have an opportunity to try and collect other insects and invertebrates with equipment provided. This will be a fun way to explore the Grange and its biodiversity!

Want to participate? Head to the first bridge over Shaw’s Creek after the Station St. entrance where we will be set up from 11-3 on Saturday, May 2nd. There will also be food available for purchase from around 11:30 until they run out. See the map at the bottom of the page and head to the red X to join us!

Adam Shoalts will be talking about his explorations of Canada’s arctic wilderness. Adam is a professional adventurer, also known as Canada’s Indiana Jones. His expeditions have included a nearly 4,000 km canoe journey across Canada’s arctic – alone. He is the author of the #1 national best seller Alone Against the North and the award winning A History of Canada in 10 Maps, also a national bestseller. His brand new book, Beyond the Trees: A Journey Alone Across Canada’s Arctic will be released October 1 by Penguin Random House. He is Explorer-in-Residence with the Royal Canadian Geographical Society, and in 2016 was named a National Champion of the Trans-Canada Trail. He is a regular guest on Canadian television and radio and has a PhD in History from McMaster University.
His new book, Beyond the Trees, will be available for purchase/signing at the event. CBC has named it one of the 40 most anticipated books of the year, and Indigo has named it their staff pick for October.

Critters in the Creek 2019

Despite the cool weather Critters in the Creek was a wonderful day! Lots of kids and adults got to explore the biodiversity of the Grange’s streams and ponds, many hotdogs and Dilly bars were consumed, and all in all everyone had a great day!

We found a lot of diversity in the invertebrates in Shaw’s Creek. This included a LOT of caddisflies and mayflies, some stoneflies, damselfly larvae particularly in the genus Calopteryx (the ebony jewelwings), dragonfly larvae, amphipods, isopods, and crayfish. In some of the slower water eddies we found some species we were surprised to see as they’re more typical of ponds but apparently these eddies provide enough habitat for them to persist. These species included water-scorpions and backswimmers. It’s clear that Shaw’s Creek houses a diverse and healthy community of aquatic insects!

We plan to do this again next spring so keep an eye out for that next year!
