Ecological Succession: A Driving Force
Ecological succession (ES) remains one of the most significant determinants of Earth’s biotic life and diversity. Defined as the process of change in the species structure of an ecological community over time, ES drives the environmental shifts of nature and conceives the biological architectures of past, present, and future landscapes.
ES can be broken into three recognized phases: primary succession, secondary succession, and climax community. Primary succession is the series of community changes that occur within an entirely new habitat that has been devoid of life—for example, after a major disturbance such as flood, fire, or volcanic release.
Secondary succession is the process by which an established community is replaced by the next set of biodiversity. Most biological communities remain in a continual state of secondary succession as communities experience minor disturbances, either natural or man-made, that inhibit or reset the successional process.
A climax community represents a stable end product of the successional sequence. Many recognize the Oak-Poplar Forest as a climax community but still acknowledge that any environment can be suddenly disorganized by random variables such as introduced, non-native species. It is said that ES will always remain as Earth is in an ever-changing state.
Today, many forget to recognize the successional phases that are undoubtedly turning all around us. Aesthetic, monetary, and time resources can, at times, skew an image, only accounting for the “now” variables. While this planning stage is necessary, a landscape may be on borrowed time without subsequent conception. Where will the landscape be in one year, one decade, one generation from now? How will it be enjoyed? Will it serve a greater purpose than its original scope? What changes have and will be exerted on this space? Questions such as these can help build upon the natural rhythms of succession while also bridging histories.
