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 ...
Secondary succession follows severe disturbance or removal of a preexisting community that has remnants of the previous ecosystem. [1] Secondary succession is strongly influenced by pre-disturbance conditions such as soil development, seed banks, remaining organic matter, and residual living organisms. [1]
This equilibrium was thought to occur because the climax community is composed of species best adapted to average conditions in that area. The term is sometimes also applied in soil development. Nevertheless, it has been found that a "steady state" is more apparent than real, particularly across long timescales.
An image of ecological succession, starting with pioneer species and ending with an old-growth forest that is dominated by climax species, which is denoted by VIII. Climax species, also called late seral , late-successional , K-selected or equilibrium species, are plant species that can germinate and grow with limited resources; e.g., they need ...
Pioneer species play an important role in creating soil in primary succession, and stabilizing soil and nutrients in secondary succession. [2] For humans, because pioneer species quickly occupy disrupted spaces they are sometimes treated as weeds or nuisance wildlife, such as the common dandelion or stinging nettle.
A seral community is an intermediate stage found in ecological succession in an ecosystem advancing towards its climax community. In many cases more than one seral stage evolves until climax conditions are attained. [1] A prisere is a collection of seres making up the development of an area from non-vegetated surfaces to a climax community.
Many studies have been conducted on old field succession, the process by which fields slowly grow back into forests over many years. While there are two types of succession, primary and secondary, secondary succession is what we think about when considering old fields. These processes may be cyclic or seral depending on the system dynamics and ...
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.
