Ecosystems can recover after a wildfire through a process called ecological succession. This process involves different stages of plant and animal species gradually returning to the area. Initially, pioneer species such as grasses and shrubs may colonize the burned area, followed by larger plant species and eventually trees. Over time, the ecosystem can rebuild its biodiversity and structure, with the help of natural processes like seed dispersal, soil nutrient cycling, and interactions between species. It may take several years or even decades for an ecosystem to fully recover after a wildfire, depending on the severity of the fire and other environmental factors.
