Celebrate Earth Month by thanking the park’s trees for all that they do. As an accredited Level II Arboretum, Madison Square Park has over 300 trees and a rich diversity of species to enjoy.

Mailboxes with writing materials will be located throughout the park for you to show your love for any tree in the park by writing a handwritten letter, composing a poem, or creating a drawing.

Place your completed letter in one of the dropboxes located throughout the park, or post your letter on Instagram and tag @madsquareparknyc
