All About Galls through Insect Plant Manipulation - Guided Walk

Please join Angeli Sahdra, Sptial Ecology Researcher from Toronto Metropolitan University to learn what a gall is and how insects manipulate plants to create them as we walk around Meadowlilly ESA.

We will meet at the Meadowlilly Bridge, located at the end of Meadowlilly Road South.

Free street parking is available on-site. Please wear appropriate clothing and footwear. This hike will be on uneven terrain and is not wheelchair accessible.

Please download iNaturalist in advance to be ready to make observations for the Great Canadian BioBlitz! If you would like help getting started with iNaturalist then arrive 15 minutes early and an iNaturalist Ambassador will be there to teach you how to use the app to make observations.

You will have to "Join" the project for your observations to count in the event - "The Great Canadian BioBlitz 2026".

Canada’s biggest nature challenge is back! The CWF Great Canadian BioBlitz returns for a second year - September 18–27, 2026, and we’re inviting nature lovers, community scientists, educators, and biodiversity enthusiasts across the country to help document as much Canadian wildlife as possible, from backyard birds to rare plants and everything in between.

The Great Canadian BioBlitz is more than just a fun challenge—it's a way to connect with nature, contribute to conservation science, and celebrate the amazing biodiversity of this country. Let’s make this the biggest and most inclusive BioBlitz yet!

Help us track biodiversity in London by participating in the Great Canadian BioBlitz and joining us on one of our many hikes! Can't wait to see you out on the trail!
