Pine- White Pine, Minnesota, Itasca County, Chippewa National Forest, Lost Forty
Old-growth forest is an environment that periodically undergoes disturbances, such as low intensity wildfire, outbreaks of disease or local blowdowns, that opens the canopy so sunshine can reach the ground and encourage the growth of pine seedlings and other sun-loving species. Without periodic disturbances old-growth pine forest may eventually be replaced by more shade-tolerant tree species. (The description is not detailed and is based on generalities- many other more complex relations can be involved.)
