The annual City Nature Challenge (CNC) is this weekend, from Friday April 29 through Monday May 2. I put together a presentation on Slideshare with a brief overview of New York City’s participation in CNC.

I’m one of the Brooklyn Borough Captains for the NYC Battle of the Boroughs, a friendly inter-borough competition among the boroughs to promote CNC participation across NYC. Following is a list of all the planned events and participating greenspaces in Brooklyn. You can also find this list on the Brooklyn CNC 2022 iNaturalist Project Journal.
