City Nature Challenge 2025
Event Description
The City Nature Challenge is a friendly, global competition to see which city can document the most wildlife using iNaturalist! From April 25-28, the Greater Phoenix Area is joining cities worldwide to explore nature in our urban spaces. The CNC is a unique event that serves to connect people to their local nature in urban or metro areas worldwide. The hope of the event is to grow volunteer community science documentation while collecting urban biodiversity data that are available to managers and scientists but most importantly have fun spending time outside!
