What is Extended Rotation with Commercial Thinning?
Extended rotation with commercial thinning is not a silvicultural system, but it provides baseline data for comparing silviculture systems. Thinning allows the remaining trees enough space to maintain high growth rates for an extended period. This process produces old-growth attributes within a relatively short time frame. The long-term replacement of old-growth forest attributes through active silvicultural measures is part of the Vancouver Island Land Use Plan for the Sayward Forest.
