The NYC Parks department maintains an online map of the city’s street trees — currently 678,674 mapped trees from 422 different species.

Our tree map includes every street tree in New York City as mapped by our TreesCount! 2015 volunteers, and is updated daily by our Forestry team. On the map, trees are represented by circles. The size of the circle represents the diameter of the tree, and the color of the circle reflects its species. You are welcome to browse our entire inventory of trees, or to select an individual tree for more information. The map only shows trees that grow on land under the jurisdiction of NYC Parks. This includes trees planted along sidewalks or other public rights-of-way. You might not see trees that are planted on rights-of-way maintained by the NYC Department of Transportation, or by the state or federal government. You will also not see trees planted on private property.

Each tree on the map is clickable; when you do so, you can see the tree’s species, diameter, and the ecological benefits. (For example, this large oak tree along Central Park West provides $540 of ecological benefits each year…from capturing storm runoff to removing air pollutants.) You can also keep track of your favorite trees, join a tree care group to help take care of the city’s trees, or record activities you’ve done to care for trees in your neighborhood.

It’s easy to become a tree steward! We host volunteers all year long. We can train you in basic activities such as watering trees, adding mulch and soil, and removing weeds and litter; as well as advanced activities such as installing a tree guard, expanding tree beds, and installing or removing stone or brick pavers.

When Melbourne, Australia assigned each of their trees an email address to report problems, people started writing love letters to their favorite trees.

“My dearest Ulmus,” the message began. “As I was leaving St. Mary’s College today I was struck, not by a branch, but by your radiant beauty. You must get these messages all the time. You’re such an attractive tree.” This is an excerpt of a letter someone wrote to a green-leaf elm, one of thousands of messages in an ongoing correspondence between the people of Melbourne, Australia, and the city’s trees.

Each of NYC’s trees has a ID number too…let’s give them email addresses! (via @halobrien_wa)
