CODIT stands for Compartmentalization of Decay in Trees, and sugar maples are darn good at CODIT! Mark Isselhardt, during the 2021 virtual Ohio Society of American Foresters spring meeting, gave an excellent microscopic and physiological explanation of how maple trees wall off and seal up old tapholes.
Why does understanding compartmentalization matter to a maple producer? Compartmentalization creates the all-important non-conductive wood that sugarmakers try to avoid with each year’s new taphole. And just in case you were wondering – how much does it matter? Through work conducted at University of Vermont’s Proctor Maple Research Center, Mark Isselhardt document sap yield declines of 70-75% when a taphole intersects non-conductive wood.
Please enjoy this 1-hour presentation led by Kathy Smith, Les Ober, and Gabe Karns. This opportunity was made available through the Woodland Stewards Friday in the Woods webinar series. Nearly 150 attendees listened to a wide coverage of beginner maple topics followed by a full hour of Q & A that ranged from more technical aspects of boiling and filtering and processing syrup to more inquisitive investigations of why the freeze-thaw cycle is necessary for making sap flow and if tapped wood has any market potential as lumber.
Despite being virtual due to COVID-19, 2021 Ohio Maple Days – or more accurately Ohio Maple Day sans the “s” – was a success. The audience, two hundred or so strong, heard presentations on tapping and updates from our ACER grants in addition to how production might be increased with red maple. A big thanks to this year’s speakers and an extra round of applause for the committee who worked hard on an event that looked quite a bit different than in years past. One silver lining to having a virtual event is that the sessions are easily recorded.

Join OSU’s Les Ober, Geauga Co. Extension, and SENR’s Gabe Karns and Kathy Smith, for this session on how to make your own syrup or explore turning your woods into a sugarbush as an income opportunity. We will talk some history, tree species to tap, how to tap and how to boil and bottle maple sap. Have a few trees in the yard or a woods that has potential? We will try to answer all your questions.
