The Great Plains are characterized by flat, open landscapes with grasses as the dominant vegetation. They receive moderate rainfall (25-75 cm annually) but not enough to support forests.

• How is its biodiversity?

The biome supports species like bison, prairie dogs, and grassland birds, along with drought-tolerant grasses and wildflowers.

• How have humans impacted the biome?

Large portions have been converted into agricultural land, leading to habitat loss, soil erosion, and declines in native species.

The Pampas, located in Argentina, Uruguay, and Brazil, are vast, flat plains dominated by grasses and very few trees. They experience moderate rainfall (25-100 cm annually) and a temperate climate.

• How is its biodiversity?

The Pampas are home to species like rheas, pampas deer, armadillos, and a variety of grasses and shrubs adapted to grazing and fire.

• How have humans impacted the biome?

Extensive agriculture and cattle ranching have replaced native grasslands with crops like soybeans and wheat. This has led to habitat loss, soil degradation, and reduced biodiversity.

It is the world’s deepest and oldest freshwater lake, holding about 20% of the Earth’s fresh surface water.

• How is its biodiversity?

Lake Baikal is home to over 3,500 species, two-thirds of which are found nowhere else, such as the Baikal seal and unique fish species.

• How have humans impacted the ecosystem?

Industrial pollution, overfishing, and climate change have affected its delicate balance, threatening endemic species.

As the largest tropical lake in the world, it supports both aquatic and terrestrial life along its shores.

• How is its biodiversity?

Lake Victoria hosts over 500 species of cichlid fish and supports various birds, mammals, and plants.

• How have humans impacted the ecosystem?

Overfishing, invasive species like the Nile perch, and pollution from agricultural runoff have severely reduced fish populations and water quality.
