Abstract: A damage survey of parkway trees in Urbana, Illinois was made to determine critical removal and repair needs of trees immediately following a severe ice storm. Siberian elm, honeylocust, Bradford pear, common Hackberry, pin oak, sycamore, green ash, and tuliptree were among the 25 major parkway tree species that sustained considerable ice damage. Larger diameter trees with broader crowns incurred most of the ice damage. Fine branching pattern, structural weakness, and higher degrees of lateral branching were associated with greater incidence of ice damage. No discernible overall relationship existed between wood specific gravity, modulus of ruptjre, or modulus of elasticity and susceptibility to ice damage.
