Assessing Wound-Induced Response Growth in Two Common Urban Tree Species

This study investigates the effect of trunk injury severity on initial tree strength loss, and how trees respond to those injuries through adaptive growth.

Factors That Influence Branch Union Strength

The Illinois Tollway Trees Initiative

The number of species that can tolerate poor-quality of roadside soils is limited. Can we increase the diversity of trees that can thrive in this harsh environment and the ecosystem services provided by urban trees through improved site preparation and design?

Quantifying and Assessing Ice Storm Damage to Trees

This project seeks to determine how best to prune trees to improve resilience to damage from ice storms.

Chicago Region Tree Census

The Chicago Region Tree Census is a scientific project to count and assess the state of trees across the seven-county Chicago region. Expected to run through 2050, the project aims to conduct a tree census every ten years. Thus far, it has completed a census in 2010 and 2020.
