New York City is aiming to increase its tree canopy cover from 22% to 30% by 2035. However, determining where to plant trees and which species to prioritize is a complex task. To address this challenge, researchers at Cornell University have created a 3D mapping tool called Tree Folio NYC. The tool uses lidar scans to provide a detailed visualization of each tree in the city, allowing planners to better understand their individual contributions to shade and direct resources accordingly. Expanding the tree canopy offers numerous benefits, such as improving air quality, reducing heat, and boosting mental and physical well-being. However, there are disparities in tree canopy distribution, with communities of color having significantly less coverage. Strategic tree placement and other improvements to urban design can help address these disparities and ensure that all residents can benefit from the positive impacts of trees. While the new urban forestry laws in New York City are a step in the right direction, maintaining sufficient funding for tree-related initiatives remains a challenge. Ultimately, successful tree planting efforts will require diverse species, healthy soil conditions, sufficient space for growth, and ongoing maintenance and monitoring. The Tree Folio NYC mapping tool can be a valuable resource for any city with lidar coverage.
