From Thursday, July 29 to Monday, Aug. 2, the Nature Conservancy of Canada (NCC) is running its Big Backyard BioBlitz. It’s an event anyone can participate in as a volunteer or “citizen scientist” by taking pictures of plants, animals and fungi wherever they are, including backyards. Participants then upload them to a smartphone/web app called iNaturalist that identifies them using artificial intelligence. The identification is later verified by experts around the world. (Full disclosure: I’m an avid user of the app and have registered for this event.) NCC: Big Backyard BioBlitz (natureconservancy.ca)
