Trees Count at Washington's Walk

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. Returning volunteers will receive additional giveaway items such as shirts, books, and hip bags as supplies last. Next, we'll provide a 30-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. For your comfort and safety, please bring water and wear closed-toe shoes to this program.
