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.
