Grassland is a kind of earth ecosystem, located in arid and semi-arid areas, which is divided into tropical grassland, temperate grassland and other types. Generally speaking, sheep and horses are often indispensable wherever there are grasslands. This kind of natural collocation scene has become a fixed pattern, which is also a necessary form of herdsmen's living needs. Therefore, the grassland is the home of sheep and horses.

Whether tropical or temperate, natural grasslands appear in environments where the growth conditions are only favorable in short seasons. In the tropics, this growing season is usually the rainy season, and in some cases, it is the season when the land is not soaked in water. In temperate grasslands, the growing season is usually a short period between wet and cold winter and dry and hot summer.
Perennial grasses grow rapidly by food stored underground, which can make good use of this short growth period to grow to the maximum and complete fruiting in a few weeks. Then, its aboveground part died, which provided potential fuel for typical grassland fires in the environment. However, the perennial roots and rhizomes under the grassland were well protected in the fire.
