One of the nation’s largest lumber producers based in Coeur d’Alene is acquiring Tricon Timber’s stud mill in St. Regis. The Idaho Forest Group, a family owned wood products company, announced the acquisition last week. The transaction is scheduled to close by Dec. 1. “The St. Regis sawmill acquisition supports our continued growth and will be an excellent strategic addition to our existing operations in Northern Idaho,” Erol Deren, Idaho Forest Group vice president of sales and marketing, said in a statement posted online. …Timber companies across western Montana have decried the lack of available timber, and in recent years significant consolidation and closures have occurred. Most prominently, Weyerhaeuser Co. merged with Plum Creek Timber Co. in early 2016.
