Secondary succession is the secondary ecological succession of a plant's life. As opposed to the first, primary succession, secondary succession is a process started by an event (e.g. forest fire, harvesting, hurricane, etc.) that reduces an already established ecosystem (e.g. a forest or a wheat field) to a smaller population of species, and as such secondary succession occurs on preexisting ...
Particularly common types of secondary succession include responses to natural disturbances such as fire, flood, and severe winds, and to human-caused disturbances such as logging and agriculture. In secondary succession, the soils and organisms need to be left unharmed so there is a way for the new material to rebuild. [9]
For example, we can examine succession in the Loess Plateau in China. In the graph on page 995 of the paper "Plant Traits and Soil Chemical Variables During a Secondary Vegetation Succession in Abandoned Fields on the Loess Plateau" by Wang (2002), we can see the initial dominance of the Artemisia scoparia, the pioneer species.
Autogenic succession can be viewed as a secondary succession because of pre-existing plant life. [6] A 2000 case study in the journal Oecologia tested the hypothesis that areas with high plant diversity could suppress weed growth more effectively than those with lower plant diversity.
Ecological succession, a fundamental concept in ecology, refers to more-or-less predictable and orderly changes in the composition or structure of an ecological community Wikimedia Commons has media related to Ecological succession .
Secondary forests re-establish by the process of succession. Openings created in the forest canopy allow sunlight to reach the forest floor. An area that has been cleared will first be colonized by pioneer species , followed by shrubs and bushes.
Seral communities in secondary succession can be seen in a recently logged coniferous forest. During the first two years, grasses, heaths and herbaceous plants such as fireweed will be abundant. After a few more years shrubs will start to appear; and about six to eight years after clearing, the area is likely to be crowded with young birches ...
Primary succession, when there is a new substrate with no existing vegetation, as after a volcanic lava flow; Secondary succession, when the substrate has sustained vegetation, as after a fire or flood; Succession (geology), in geology, a group of rocks or strata that succeed one another in chronological order
