TreeKeeper Database

Prospect Park Alliance recently surveyed nearly half of the park's 30,000 trees, through a a $75,000 Urban Forestry Grant from the New York State Department of Environmental Conservation.

Using the TreeKeeper Interactive Map, you can identify all of the mapped trees in Prospect Park. These currently number over 12,000, with interior woodland areas of the park still to come. Use the embedded map below or visit the Prospect Park TreeKeeper website

To use the TreeKeeper Interactive Map:​

  • Use the control panel on the left to select Map Tools, Map Layers, Tree Benefits, Search and Report Builder.
  • Use the Search function to search by species, trunk size and more.
  • Learn more about individual trees by selecting them on the map and clicking the green arrow on the Site Information pop up box.

The Tree Survey is part of Prospect Park Alliance's mission to keep Brooklyn's Backyard green and vibrant. Help us keep the park's tree green and healthy by contributing to our commemorative tree program and Arbor Day community planting.
