Thee Natural Fire Regime of thee Savanna

Fire acts a powerful selectiva pressure shaping thee composition and structure of savanna vegestionion. Without periodic burning, many savannas would gradually convert into closed-canopy woodlands or forests, as fire-sensitiva woody species outcompetize sun- loving classes.

Large mammals such as s elephants, buffalo, giraffes, and various antolope species tend to avoid thee expectate danger of active fires.

Smaller animals - pyllarly incorpiates, reptiles, and small mammals - face more direct risks from fire. Many species evade flames by burrowing into the soil, hiding undeid rocks or fallen logs, or retreating to unburned concers.

Over time, as grachess mature andd woody plants re- equisish, thee habitat gradually transitions back toward pre- fire conditions.
