Challenge. This is a global effort to observe and document as much urban biodiversity as

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 2020 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!
What is community science?
Community science is best described as a partnership between the public and professional scientists that can help answer questions at local and sometimes global scales that scientists couldn’t answer on their own. This can be done in person and online.
Why should you participate in the CNC?
It’s fun—and it’s a great way to spend some time out in nature destressing, while also learning about urban biodiversity and helping Greater Phoenix Area find as many species as possible over 4 days. You’ll also be helping scientists collect valuable information on urban biodiversity.
Who can participate?
Anyone in the Valley of the Sun who has access to a camera (cellphone or digital) and the internet can participate. Please share this flyer with your friends and family.
How do you participate?
STEP 1 - APRIL 30-MAY 3:
STEP 2: MAY 4-MAY 9
Even if you are unable to get out to make observations or if you are outside the Greater Phoenix Area, you can still help us by identifying the observations found by participants. It’s fun to see what people are finding! See our resources page for information about online iNaturalist trainings.
