Volunteer with NYC Parks for our decadal tree census! At this event you will receive a tote bag with all the materials needed to count trees. NYC Parks staff will 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 parks across the city. For your comfort and safety, please bring water and wear closed-toe shoes to this program.
