CNC is an annual global bio-blitz at the end of April, where cities are in a collaboration-meets-friendly-competition to see what can be accomplished when we all work toward a common goal. The tool of choice is iNaturalist, which is a Citizen Science app that uses AI to help ID plants and animals. It also helps you document and organize your observations, let's experts review and verify observations, etc.
