This resource explores the concepts of ecological succession, detailing the processes of primary and secondary succession. Primary succession begins in lifeless areas with pioneer species such as mosses and saplings, gradually transforming the environment into a thriving ecosystem. Secondary succession occurs in previously colonized regions that have experienced disruption, like fires or logging, allowing quicker recovery due to existing soil and seeds. We’ll define key terms and discuss the significance of climax communities, where ecosystems reach stability and balance.

Daily Notes • Define the following terms in your own words: • Pioneer – • Colonize – • Climax –
Succession • The process of environmental change from field to forest • Primary • Secondary • Climax (Final community)
Primary Succession • Starts with an area that has no topsoil • Very first plant and animal species move into the area – “Pioneering” • Pioneer species slowly change the ecosystem…
Pioneer species • Saplings (baby trees) • Mosses • Small bushes
Primary Succession • Meadow Saplings grow (young trees) Taller trees create a young forest
Secondary Succession • Happens in an area that has already been colonized, but was damaged • Fire • Severe logging • Happens much quicker than primary succession because there is already some soil, seeds and other remains of previous ecosystem
Climax Community • Ecosystem thrives and is in balance • Happens at the end of both kinds of succession
