The City Nature Challenge is an international four-day event for people to find and document plants and wildlife around them, in cities around the world. It’s a bioblitz-style competition rooted in citizen science and created by community science staff at the Natural History Museum of Los Angeles County and the California Academy of Sciences. Help the South Florida team go up against other global cities to see who can make the most observations of nature, find the most species, and engage the most people!

As part of Frost Science’s America250 initiative, your participation also contributes to a nationwide goal of 2.5 million “Acts of Science” in partnership with SciStarter, each observation helping advance real scientific research and impact. Learn more at frostscience.org/america250.

There are events happening all across South Florida, but you can participate from anywhere: your backyard, a local park, or even underwater. Log into iNaturalist.org or download the app. Then, get outside! Submit your plant and wildlife observations between Friday, April 24 and Monday, April 27 to join the effort.

Community Service Hours

We know many environmentally-minded students are looking for volunteer opportunities. Here’s how to receive service hours for participating in City Nature Challenge:

  • Create a FREE account on iNaturalist.
  • Get outside and photograph plants and wildlife, or evidence of them.
  • Upload these photos either through the iNaturalist smartphone app or inaturalist.org
  • Email muve@frostscience.org with your username so we can confirm you have uploaded observations. Please include your full name in the subject line.
  • For every 10 observations you will receive an hour of community service. We will award a maximum of 10 hours, or 100 observations, per person.
