Winter Tree Identification Workshop Recently Held For Area Residents –– U of I Extension News, March 1, 2017
Winter Tree Identification Workshop
Chris Evans, Research Forester for University of Illinois Extension recently presented a workshop on Winter Tree Identification. The workshop had over 30 participants from Bond, Clinton, Marion, Jefferson and Washington Counties. The cool temperatures and intermittent rain did not deter them from learning in an outdoor classroom.
The class was held at the Washington County Conservation area south of Nashville. The Conservation Area includes a seven-mile trail through the 1440 acres of the park which includes forest, lake shore and fields. The class gathered under a shelter to receive the basic techniques used to identify trees where participants learned the vocabulary and terminology needed to use a dichotomous key. A dichotomous key is a tool that asks questions in a series of two. The process of eliminating one possibility as you progress will eventually lead to identifying a given tree. These keys are also available for wildflowers, mammals, fish and other things in nature to aid the student in properly identifying items in nature.

Participants in the U of I Extension Winter Tree Identification workshop used their new identification skills during a hike with Forester Chris Evans.
After the classroom portion of the workshop participants trekked into the woods putting their new skills to work using the dichotomous key. Evans also shares additional ways of identifying trees by observing additional clues such as habit, location of the tree, fragrance of the bark, overall shape of the tree, carryover fruit and more. Evans describes this as his ‘Gestalt’ method of obtaining clues that assist in the proper identification of a tree.
