The Ohio Woodland Stewards Program will hold a Winter Tree ID workshop twice in the coming weeks: Oct. 30 in Chardon in northeast Ohio (this offering in now full) and Nov. 6 in Hamilton near Cincinnati.
The workshop will give participants in-depth training and practice on identifying trees without leaves, said one of the event’s instructors, Kathy Smith. Smith directs the stewards program, which is part of the College of Food, Agricultural, and Environmental Sciences at The Ohio State University.
“This is an advanced class for individuals who are familiar with using a dichotomous key,” she said. A dichotomous key lets a user identify an unknown species through a sequence of questions. In this case, non-leaf traits like bark, fruit and twigs will be the focus.
Participants also will be eligible for four hours of continuing education credit under the Ohio Forest Tax Law Tax program, Smith said.

Get indoor, outdoor practice

The schedule, topics and cost will be the same at both locations. The agenda includes an introduction to winter tree identification, details on using a dichotomous key, practice indoors on samples and, weather permitting, practice outside on trees.
Registration is $35 and includes lunch. The registration deadlines are Oct. 23 for the Chardon workshop and Oct. 30 for the Hamilton workshop.
