Secondary Succession • The re-growth of a community after it is disrupted – Can happen as long as soil is still present – Examples: forest fire, cleared forest, plowed field, etc.

Secondary Succession
Climax Community • Mature community dominated by slow-growing, well-adapted climax species (i. e. large trees & animals)
Biodiversity • The variety of organisms present in an area – High degree of biodiversity in a mature community – Helps to stabilize the community
