Matt Wallace is the organizer and founder of the Calgary City Nature Challenge (CNC). April 25-28, 2025 marks the 7th annual event for our city, but what’s it all about? This presentation will tell the story of how the CNC has been a catalyst for the growth of citizen science in Calgary and dive into what we have learned about our urban biodiversity and how you can help to protect it by sharing your observations.
