Tree Traits and Tollway Troubles: Trait-based Approaches for Predicting and Restoring Soil Function
Meghan Midgley, PhD, the Morton Arboretum
Trees alter the soils in which they grow by contributing organic matter to the soil, such as leaf and root litters and root exudates. However, given the existence of over 60,000 species of trees, a critical challenge lies in determining how soils dominated by different species function. In this talk, Medgley will demonstrate how tree leaf and root traits (such as deciduous vs. evergreen leaves) can be used to simplify relationships between trees and soils and predict how forests will respond to environmental changes. Additionally, she will highlight a unique research project designed to apply basic knowledge about tree effects on forest soils to enhance urban tree biodiversity and ecosystem health along the Illinois Tollway.
