Trees Count

Volunteer with NYC Parks for Trees Count 2025! At each event you will receive a tote bag with all the materials needed to count trees. Next, we’ll provide a 20-minute training session that includes the basics of tree identification and how to measure and assess each tree.

Using our Tree Census app, you’ll split up into different zones within the park to start counting trees! After completing your first training event, you are welcome to continue counting trees on your own in smaller parks across the city.
