Small plants grow but are eventually replaced by larger plants.
Secondary succession, where plant and animal life recolonize an area after a disturbance has disrupted an existing ecosystem.
After a forest fire, an ecosystem goes through a process called succession. This is the gradual change in plant and animal communities over time as the ecosystem recovers and regenerates. Initially, pioneer species colonize the area followed by a more diverse community as succession progresses.
After a fire destroys a forest, secondary succession occurs where grasses and shrubs start to grow first, followed by small animals like rodents and insects. As these plants and animals establish, larger plants and animals such as trees and birds gradually return over time.
A wilderness forest fire typically leads to secondary succession. This process occurs in areas where a disturbance, like a fire, has cleared out vegetation but left the soil intact. Unlike primary succession, which starts from bare rock or lifeless environments, secondary succession allows for quicker recovery as existing soil and seed banks remain, facilitating the regrowth of plants and the reestablishment of the ecosystem.
It depends on where the fire occurs, and what kind of habitat is present. In general, most often, grasses and forbs will become reestablished first, followed within a couple years by the return of sapling trees and woody plants. Over many decades, fast-growing trees will become reestablished first, then eventually give way to old-growth forest types of trees.
Secondary succession
Secondary succession
The two types of succession are primary succession and secondary succession. Primary succession occurs on bare rock or soil with no previous life, while secondary succession occurs in areas where an ecosystem was previously established but has been disturbed, such as after a forest fire or clear-cutting. An example of primary succession is the colonization of a volcanic island, while an example of secondary succession is the regrowth of vegetation after a forest fire.

Secondary succesion because the forest or life has to grow again! :)
secondary succession
Primary succession occurs in areas where no soil is present, such as on newly formed volcanic rock, while secondary succession occurs in areas where soil is already present, such as after a forest fire. An example of primary succession is the colonization of barren land by lichens, which break down rock to form soil. An example of secondary succession is the regrowth of vegetation in an area that was previously cleared by a logging activity.
In grasslands, or forests, anywhere really, after a flood or a fire, for example.
