Multi-layered forest (flerskiktad skog) is a term describing the height distribution of trees in a forest stand. In a multi-layered stand, there are trees in several different size classes.
Multi-layered forest is a collective term for stands that are neither single-layered nor two-layered. A multi-layered stand can be fully stratified.
In traditional clearcut forestry, stands are most often single-layered. In continuous cover stands, it’s much more common for the stand to be multi-layered—or even fully stratified.
