Secondary succession, type of ecological succession (the evolution of a biological community’s ecological structure) in which plants and animals recolonize a habitat after a major ecological disturbance significantly alters an area but has not rendered it completely lifeless.
Secondary Succession Definition. One of the two main forms of ecological succession, secondary succession is the process relating to community growth or change that takes place when a habitat is disturbed or damaged.
Secondary succession is the ecological succession that occurs after the initial succession has been disrupted and some plants and animals still exist. It is usually faster than primary succession as soil is already present, and seeds, roots, and the underground vegetative organs of plants may still survive in the soil.
Secondary succession is a type of ecological succession that occurs in places disturbed by major events like floods, landslides, or human activities but is not entirely devoid of life. In this process of succession, plants and animals re-establish themselves in the destroyed ecosystem.
Secondary Succession Definition. What is secondary succession? In biology, secondary succession is defined as the re-establishment or re-colonization process of a full-fledged ecological community from the remnants of the soil after an ecological disturbance.
Secondary succession happens when a climax community or intermediate community is impacted by a disturbance. This restarts the cycle of succession, but not back to the beginning—soil and nutrients are still present.
Definition: Secondary Succession. The predictable change in a community following a disturbances that does not completely destroy the soil such as a forest fire, hurricane, flood, or farming. The disturbance significantly alters the area, but it is not rendered completely lifeless.
Secondary succession differs from primary succession in that it begins after a major disturbance—such as a devastating flood, wildfire, landslide, lava flow, or human activity (farming, road or building construction, or the like)—wipes away part of a landscape.
Secondary succession occurs in areas where a biological community has already existed but some or all of that community has been removed by small-scale disturbances that did not eliminate all life and nutrients from the environment.
Succession as progressive change in an ecological community. Primary vs. secondary succession. The idea of a climax community.
