The pulp and paper industries generate annual shipments valued at more than $14 billion. The forest products industry ranks second in exports, with shipments valued at almost $11 billion. It is also the main, and in some circumstances only, source of manufacturing activity in more than 250 municipalities in the province. The forest industry has slowed in recent years because of the softwood lumber dispute. This industry employs 68,000 people in several regions of Quebec. This industry accounted for 3.1% of Quebec's GDP.
