Grasslands are large terrains of grasses, flowers and herbs. In the winter, grasslands are dull and lifeless because of the weather. In spring, the grass begins growing rapidly and flowers start to bloom. Grassland soil is rich in nutrients and is the perfect place for the growth of plant life. There are two divisions of grasslands. The first division is a tropical grassland, called a savanna. The other division is called temperate grasslands. Grasslands favor climates that are hot and dry. The two types of grass that occupy grasslands are tall-grass and short-grass. Tall-grass usually lives in a climate that is moist and wet. Short-grass lives in a climate that is hot and dry.


Geographic Distributions:

Grasslands are distributed around several places in the world. In North America, grasslands are present in the southwest Canada, the western United States, and on parts of the west coast of Mexico. In South America, grasslands occupy Argentina. Grasslands are also in the southern part of Africa, the eastern border of Europe and the western border of Asia, and western Asia. Lastly grasslands occupy most of the continent Australia.


Dominant Flora and Fauna:

There are many dominant flora and fauna in grassland regions. Most animals only eat plants because of the amount of grass. There are also some animals that eat other animals. Some common plants include Buffalo Grass, Sunflower, Crazy Weed, Asters, Blazing Stars, Coneflowers, Goldenrods, Clover, and Wild Indigos. Some types of fauna consist of gazelles, zebras, rhinoceroses, wild horses, lions, wolves, prairie dogs, jack rabbits, deer, mice, coyotes, foxes, skunks, badgers, blackbirds, grouses, meadowlarks, quails, sparrows, hawks, owls, snakes, grasshoppers, leafhoppers, and spiders.


Abiotic Factors:

Grasslands develop wherever there is not enough rain to support a forest, and not too much light to form a desert. Annual rainfall in grasslands is between 10 to 30 inches. There is enough rain to support grass and in some places, a few trees. Wind is another abiotic factor. In the winter, grasslands get cold and very windy. In the summer it can also be windy, but usually it dies down. Grassland fire is very common. Fires can affect grasslands a great amount. They can kill the grass and the animals living in the grassland. However, fires can also help grasslands. Fires clear forests so grasslands can thrive. Fires also destroy trees, plants, and other dead plant materials. After these are destroyed, the grass grows longer and healthier. Lightning-initiated fires usually occur in late spring but can also occur during the summer.
