Vitals and Climate of Grassland

Grasslands vary all over the world. Many of the grassland areas exist in North America in the U.S. This intresting biome is also in South America, Europe, and even some areas in Africa. The animals and plants range depending on where the area is in the world. The North American grassland is called the Praires, the South America region is called the Pampas, Europe is called the Steppes, and the parts of South Africa are named the Velt and Savanna.


In the North American Praire, many of the abiotic factors consist of buffalo grass, coneflowers, and clover. Rainfall can range to around 30-40 inches of rain a year. The climate is warmer in the spring and summer (65-80 degrees), and chilly in the winters (close to 30 to 40 degrees can be the coldest). The grass by the East coast is very tall, and the climate is humid and wet. The grass near the West coast is much shorter, and the winters are cold, and the summers are rainy. European climates are similar, but they have a little colder winters. Rainfall is about the same, and the springs and summers are warm and comfortable.

South America's grassland regions are similar to the ones in Africa and some of North America. The climate is humid and moist through most of the year (70-95 degrees). Grasslands tend to get more precipatation in the southern hempisphere than the northern. African climates are hot and humid, and they tend to get little rainfall (10-30 inches). These areas have less plants because of the amount of rainfall .

Fun Facts

- If a fire occurs on a grassland area, it can spread as fast as 600 feet per minute.

- There are mostly herbivores living in the European grasslands, and there are mostly carnivores living in African grasslands.

- About one quarter of the earth is covered with grassland regions.

- Grasslands have more short plants than large ones, such as trees.

Ecological Concerns

Although these beautiful areas of wide opens spaces are breath taking, there are many concerns that grassland areas are decreasing in size and population. The amount of rainfall that grasslands in Africa, South America, and even North America are recieving are minimal. This is partially due to global warming. Many people are moving into these areas and are overtaking animal's habitats. When crops are being grown in the area, pests and disease can spread, and this affects the plant life in grassland regions. This biome is so important to the world because it is a very wide spread and popular area for animals and plants. Its climate is perfect for many species, so they settle here. Without the grassland area, many animals and plants would die out, and we as the people would loose many resouces such as trees. Some endangered species of this biome are the African zebras and the American bison. The zebras are dying off because their predators are eating them all, and the bison is dying because many of its resources like its food are limited. They resources are becomeing depleated because of the amount people farming the land. Hopefully the beautiful scenaries will not disappear as long as we protect the grassland areas.

Food Webs

The photo above shows the food web in an African grassland. There are few primary producers (grass, trees), and there are many primary and secondary consumers that are vital to the area. The photo below represents the North American grasssland areas. There are many herbivores or hetrotrophs.
