Woods Work: Learning Through the Game of Logging

When John Adler, at the age of 23, first heard Swedish logger Soren Eriksson talk about new techniques for harvesting trees safely and efficiently, he saw an opportunity. Adler had been cutting wood since he was a kid – starting with a bowsaw – and was fresh out of Paul Smith’s College and looking to make a living in the woods.

“In logging, you get paid for what you get done. There’s no hourly rate there. The more wood I could cut and the more easily, the more money I made,” he said, and following Eriksson’s methods, Adler learned how to work more efficiently.

In 1983, Adler became an instructor in the new teaching method Eriksson had devised, called Game of Logging (GOL). More than 40 years later, he still lauds Eriksson’s vision of teaching in small groups, using hands-on instruction and repetition. Participants are scored on different techniques taught through the class in what Adler describes as friendly competition. “We don’t try to cover a whole bunch of info in one day,” he said. “We just start at the beginning and repeat it through the day until we get it.”

In 2001, Adler and David Birdsall founded Northeast Woodland Training, where they teach all four levels of GOL, as well as other logging and chainsaw courses. These photos are from a Level 1 class this past October in Guilford, Vermont, where Adler covered topics that included proper personal protective equipment, checking saws to make sure they’re safe, notching, bore cutting, and creating a comprehensive felling plan.

Discussing logging

Stump work
GOL participant Will Seibert works on a stump during a technical exercise. The goal is to work with the tip of the chainsaw bar to practice cutting straight, horizontal lines in preparation for making a bore cut.

Tree size
Participant Jacob Fortier looks through his raised hands to evaluate the weight of a tree’s crown and to determine if the tree leans in a way that will affect the direction it will fall.

Forester marker
Doyle set this stake to mark where he thinks the tree he cuts will fall. An important part of the GOL Level 1 training is creating a felling plan and explaining that plan to the instructor and other participants. “We look at the tree, and we determine the reasonable direction of where it will fall,” Adler said. “We ask the person felling the tree to explain their plan – tell us about any hazards, what the lean of the tree is, where you’re going to escape to when the tree starts to fall, what is your hinge thickness and length going to be, and how are you going to back-cut it.”
Examine stump
Doyle and Adler examine the stump of the felled tree and discuss the process.

Doug - If your comment on the one glaring error when felling is referring to the third picture of John Doyle, I suspect that is not a picture of felling. The tree is already on the ground, yet the saw is on the stump with chips flying. The saw is also oriented to cut vertically - cutting downward (not horizontally, as you would expect if finishing the felling cut.) My bet is that he has returned to the stump after the fall and is cutting the tree off the stump in that photo.

John Adler (and his business partner, David Bridsall) are top-notch instructors. They take the time to make sure participants understand WHY to apply the various techniques, not just “do this”. That understanding helps you retain the techniques learned and also gives you a starting point if you need to modify your approach to fit unique situations.

I took my first GOL class in 2003, thinking I’d just take Level 1. I was so impressed that I ended up taking levels 2, 3, and 4 (including both the landowner and the pro logger versions of level 4). Over the years, I’ve repeated level 3 & 4 as refreshers.

I’ve become something of a GOL evangelist. In my opinion, anyone working in the woods with a chainsaw should consider these classes.

A Really nice article. I took this course a few years ago with Bill Girard, sponsored by the MA Forest Association. Everything you report is exactly as I recall doing with one glaring exception. The feller should not be anywhere near the falling tree. One has to have an escape route. The picture shows the opposite!
