Prairie

In North America

Prairie grasses

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.

Fire

Fire is an important part of prairie ecology; natural and human-induced fires were common in historic prairie areas, rejuvenating the herbaceous species, and top killing trees and brush. Grazing by animals such as the American bison and prairie dogs also helped maintain the original prairie ecology. Small areas of prairies also exist in eastern North America. It is possible that these were created by Native Americans by periodic burning. One such area was along the southeastern shore of Lake Erie in what is now Pennsylvania and New York; another was between Seneca Lake and Cayuga Lake in present New York.

Preserved prairies

Significant preserved areas of prairie include:

• Grasslands National Park, Saskatchewan
• Cypress Hills Interprovincial Park, Alberta and Saskatchewan
• Midewin National Tallgrass Prairie, in Will County, Illinois
• Neal Smith National Wildlife Refuge, Iowa
• Konza Prairie, Manhattan, Kansas
• Tallgrass Prairie National Preserve, Kansas
• Tallgrass Prairie Preserve 32,000 acres (130 km²), Oklahoma
• Nine-Mile Prairie, Nebraska
• Zumwalt Prairie, Wallowa County, Oregon
• Richard Bong State Recreation Area, in Kenosha County, Wisconsin
• Hoosier Prairie, Lake County, Indiana
• Jacobsburg Environmental Education Center, Pennsylvania
• Clymer Meadow Preserve, Hunt County, Texas
• Tallgrass Aspen Parkland, Manitoba & Minnesota

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 Ukraine and Western Germany.
