During the cleanup after the 9/11 attacks, a volunteer noticed a still-green tree among the burnt wreckage. The Parks Department and the Citywide Nursery saved the tree and brought it back to health. The "survivor tree," as its become known, is a pear tree that now stands at over 30ft. It is over four times as tall as it was when volunteers pulled it from the rubble! The tree now stands in the 9/11 Memorial Plaza and is a wonderful symbol of the amazing ability for both nature and mankind to overcome obstacles.
