City Nature Challenge

April 25 to 28, 2025

You can support biodiversity by documenting the huge variety of species that call our municipality home. The City Nature Challenge is an annual bioblitz where cities around the world compete to make the most observations of nature in a single weekend. The focus is on wild plants, animals, fungi, bugs, and more.

All you need to do is make an observation on iNaturalist using photos or sound recordings between April 25 and April 28, 2025. Please don’t include photos from zoos, museums, or your pets (no matter how adorable).

Get involved by registering for one of our events below or by participating on your own, with friends, or family.

Posting Observations

Learn how to make and add an observation and a whole lot more by checking out the iNaturalist getting started guide.

  • Location of the observation is important, so if you have your phone’s location data turned off you will need to add the location manually.
  • If it’s not wild (e.g. a domestic pet or farm animal) be sure to mark the observation as captive/cultivated.
  • As you gain experience, feel free to help identify other people’s observations.
