The City Nature Challenge is a friendly worldwide competition among cities to see whose residents can spot and identify the most wildlife. Help us document the awesome biodiversity in the Valley of the Sun by making as many observations of living organisms as possible from April 26 to April 29 through iNaturalist. This is Phoenix's 4th year participating and is co-organized by Educating Children Outdoors (ECO), SciStarter, Barrett Honors College, Central Arizona Conservation Alliance, Mary Lou Fulton Teachers College, and Maricopa County Master Naturalists. What is the CNC? The City Nature Challenge (CNC) was created by the California Academy of Sciences and the Natural History Museum of Los Angeles County. The event started as a friendly competition between two cities but quickly grew into an international event with over 200 countries participating in the most recent challenge. 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 while spending time outside!
