Illinois Forest Distribution

Welcome to the new Illinois Forestry web site. It is designed to raise awareness, inform, and most importantly educate citizens, students, teachers, landowners, environmental groups, natural resource managers, foresters, and loggers about forestry and Illinois' most valuable, renewable natural resource - trees. Please let us know if you have any questions regarding the content of this site or suggestions for improving it.

Autumn colors are upon us! However, have you ever wondered how and why tree leaves change from shades of green to majestic hues of yellow, red, orange, and purple? Professor Jeffrey O. Dawson of the University of Illinois at Urbana-Champaign provides an in-depth look into the "Who, What, When, Where, and How" of autumn foliage physiology and patterns.
