The work accomplished under this project involved Intervine hiring residents that went through The HOPE Program's green job training program and job readiness program to perform a tree census in the Hunts Point neighborhood of the Bronx, collecting data on the location and health of trees to support future stewardship efforts. In these efforts the Intervine tree census crew performed over 3,000 health assessments on trees located within the Hunts Point neighborhood of the Bronx. Throughout this tree census, the crew gained on site experience and enhanced their knowledge of local street trees and tree pits in the New York City area. By going through extensive training the crew gained experience in proper data collection for how to determine tree health and enhanced their maintenance skills for New York City’s street tree needs.

Each health assessment looked into different tree health metrics that help record tree health variables on individual trees. The five metrics used to assess street tree health are determined by:

Discoloration - the portion of the canopy with different coloration than a healthy tree of the same species
Defoliation - the proportion of the canopy with holes in leaves or missing portions of leaves
Crown Dieback - measures the percent of fine twig dieback in the tree’s crown area
Crown Light Exposure - a visual observation determining how many sides of the tree has access to sunlight
Crown Vigor - a measure of overall tree health

Through these assessments, we were able to calculate the stress percentiles of each tree in the Hunts Point area. This scale is read by 0% being no stress or very low stress to 100% being very stress or almost dead.
