Mature hardwood trees would appear in the process of secondary succession over hundreds of years. This is due to the slow growth of these trees and the time it takes for the ecosystem to become established enough for them to thrive.
In the process of secondary succession, mature hardwood trees would be expected to appear within the timescale of hundreds of years. This is because secondary succession is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat.
Examples include areas which have been cleared of existing vegetation such as after a fire. Early stages of succession involve grasses and shrubs, with larger plants and trees appearing as the ecosystem gradually recovers. The introduction of mature hardwood trees is usually one of the final stages of this ecological succession, as these species grow slowly and require a more established ecosystem to thrive.
