NYC 2015 Street Tree Census
What is being screened?

Acer, Ulmus, Populus, Alnus, Betula, Fraxinus, Pinus, Quercus, and Juniperus. This transparent genus list is a starting hypothesis, not a clinical ranking. Street trees exclude yards, parks, and most forest vegetation.

Tree Census uses 2010 tracts; the corridor boundary uses 2020 tracts. A later correlation analysis should harmonize geography first.
