See The Results The New York City Street Tree Map This map and associated data is the backbone of Parks’ internal forestry management database, and supports short- and long-term agency operations.

The use of innovative geospatial technology and a strong quality review process has yielded an exceptionally accurate inventory of street trees. Volunteers completed 34 percent of the census. The 2,241 volunteers is double the number that participated in 2006. Surveyors mapped 666,134 street trees on 131,488 blocks in New York City, walking a total of 11,093 miles. The 2016 inventory tops all previous efforts in size and scope. Using both high tech tools and survey wheels, tape measures, and tree identification keys, citizen mappers helped us create a spatially accurate digital inventory of NYC’s street trees. TreesCount! 2015-2016, our third street tree census, brought more than 2,200 volunteers together in the largest participatory municipal urban forestry project in United States history.
