Both temperate grasslands and tropical savannas are maintained by grazing herbivores. Grazing animals such as zebras, elephants, bison, and prairie dogs help to keep the grasses short, which allows for broad expanses of open grasslands. These biomes also have fire-adapted vegetation that can be stimulated by periodic fires, which are often set intentionally by humans or started naturally by lightning strikes.
