[7] [8] In 1859 Henry David Thoreau wrote an address called "The Succession of Forest Trees" [9] in which he described succession in an oak-pine forest. "It has long been known to observers that squirrels bury nuts in the ground, but I am not aware that any one has thus accounted for the regular succession of forests."
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 ...
Forest succession is the process by which species recover and regenerate after a disturbance. The type of disturbance, the climate and weather conditions, the presence of colonizing species, and the interactions among species all influence the path that succession will take. Species diversity and composition fluctuate throughout succession.
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 ...
These forests are the result of ecological succession, a long progression of different plant species over centuries. One possible sere is from bare ground, it would start with weeds, then shrubs, weedy trees (such as mulberry), then coniferous trees (such as juniper) and additional types such as ash lead to a mixed mesophytic forest.
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. Over time, trees that were characteristic of the original forest begin to dominate the forest again. [5]
Three forest stands Stand dynamics stages during succession. A forest stand is a contiguous community of trees sufficiently uniform in composition, structure, age, size, class, distribution, spatial arrangement, condition, or location on a site of uniform quality to distinguish it from adjacent communities. [1]
The succession culminates in a climax community, the forest. Many intermediate tree stages develop prior to establishment of a climax community. The forest type depends upon climatic conditions. The climax forest may be: Oak-hickory climax forest In dry habitat oaks and hickories are climax vegetation.
