Join the City Nature Challenge!

April 28 - May 1, 2023 | Ongoing during this time period


Each year the City participates in a global bioblitz to document the nature living in our urban environments. Be a part of this global citizen science effort and learn more about the plants and animals in your neighborhood by participating.

This year, the City is participating in City Nature Challenge South Florida (CNCsofl), a project of the City Nature Challenge, in order to get a snapshot of the biodiversity in our area.

How to participate:

  1. Download the iNaturalist app from Google Play or the App Store, or from www.inaturalist.org
  2. Head outside and make observations between April 28 and May 1 anywhere in South Florida - including Palm Beach, Broward, and Miami Dade counties. 
  3. That's it! All observations made within those dates will be automatically added to the South Florida iNaturalist project

What counts as an observation?
Observations should be of wild specimens. Make observations of the birds, butterflies, insects, and mammals that come and go from your yard, or the plants and trees you see walking around your neighborhood or through the City parks and natural areas. Try to avoid observations of plants you planted in a garden or pot, pets, or animals in captivity.

I'm an expert, how can I help?
Observations made between April 28 and May 1 will automatically be added to the City Nature Challenge Boca Raton Project. Before May 9, as many of those observations as possible need to be identified. If you have a strong knowledge of native plants and animals, please consider taking time to identify observations!
