What Happens If A Forest Ecosystem Is Disturbed?


Michigan Environmental Education Curriculum
Forest Ecosystem

A forest ecosystem can be disturbed by a fire or by tree removal.

When a forest is disturbed, a new forest may grow in its place.  This is called secondary succession.

Secondary succession = old forest > old forest is disturbed > new forest grows where old forest used to grow.

The forest ecosystems that you see in Michigan today are a result of secondary succession.
