In North America
Lands typically referred to as "prairie" tend to be in North America. The term encompasses much of the area referred to as the Great Plains of the United States and Canada. In the U.S., the area is constituted by most or all of the states of North Dakota, South Dakota, Nebraska, Kansas, Oklahoma, Texas, Colorado, Wyoming and Montana, and sizable parts of the states of Indiana, Illinois, Iowa, Wisconsin, Missouri, and Minnesota. The Central Valley of California is also prairie. The Canadian Prairies occupy vast areas of Manitoba, Saskatchewan, and Alberta. There is only 2% of prairie land left in the U.S.citation needed
Drought
In spite of long recurrent droughts and occasional torrential rains, the grasslands of the Great Plains are not subject to great soil erosion. The deep, interconnected root systems of prairie grasses firmly hold the soil in place and prevent run-off. These deep roots also help prairie plants to reach water in even the driest conditions. The prairie evolved to survive in extreme conditions and suffers less damage from dry conditions than the farm crops which have replaced many former prairies.
Preserved prairies

Virgin prairies
Virgin prairie refers to prairie land that has never been plowed. Small virgin prairies exist in the American Midwestern states and in Canada. Restored prairie refers to a prairie that has been reseeded after plowing or other disturbance.
Prairie garden
A prairie garden is a garden primarily consisting of plants from a prairie.
In the world
Prairies are considered part of the temperate grasslands, savannas, and shrublands biome by ecologists, based on similar temperate climates, moderate rainfall, and grasses, herbs, and shrubs, rather than trees, as the dominant vegetation type. Other temperate grasslands regions include the Pampas of Argentina, and the steppes of Russia and Central Asia.
