The recovery from the fires began almost immediately, with plants such as fireweed appearing in a matter of days after a fire had passed. While surrounding national forests did some replanting and even dispersed grass seed by airplane, the regeneration in Yellowstone was generally so complete that no replanting was even attempted. Though some small plants did not immediately re-assume their pre-fire habitats, most did, and the vast majority of plants regrew from existing sprouts which survived the heat from the fires. There was a profusion of wildflowers in burned areas, especially between two and five years after the fires.
