HARRIS, Michigan — The Great Lakes Timber Professionals Association — the same organization that unites members and aficionados for the Great Lakes Logging and Heavy Equipment Expo — brought its Spring Celebration to the Island Resort and Casino Tuesday. The convention featured speakers, 50 exhibitors, a luncheon, an award presentation and prizes. …With the industry in a slump, the gathering of loggers and truckers discussed the state of the sector. Marty Ochs from the Green Bay Innovation Group addressed the perceived need to bring saw mills and logging jobs back to local hands. Ochs spoke specifically about Wisconsin, mostly, but the American Loggers Council (ALC) said the problem isn’t restricted to the Great Lakes Region. Nationally, within the last 15 months, 50 mills have closed, resulting in the loss of 10,000 jobs, reported Scott Dane, executive director of the ALC. “We’re not having any less demand for wood products; we’re just importing it from other sources,” Dane said.
