Later this month, cities around the world will be competing to see who can make the most observations of nature, find the most species, and engage the most people in the 2019 City Nature Challenge.

The City Nature Challenge takes place in 2 parts: from April 26 – 29 (taking pictures of wild plants and animals) and April 30 – May 5 (identifying what was found).

A list of participating cities, as well as information about how to get involved, can be found here.
