Prairies are ecosystems considered part of the temperate grasslands, savannas, and shrublands biome by ecologists, based on similar temperate climates, moderate rainfall, and a composition of grasses, herbs, and shrubs, rather than trees, as the dominant vegetation type. Temperate grassland regions include the Pampas of Argentina, Brazil and Uruguay, and the steppe of Ukraine, Russia, and Kazakhstan. Lands typically referred to as "prairie" tend to be in North America. The term encompasses the area referred to as the Interior Lowlands of Canada, the United States, and Mexico, which includes all of the Great Plains as well as the wetter, hillier land to the east.
Theodore Roosevelt National Park is an American national park of the badlands in western North Dakota comprising three geographically separated areas. Honoring U.S. President Theodore Roosevelt, it is the only American national park named directly after a single person.
Tallgrass Prairie National Preserve is a United States National Preserve located in the Flint Hills region of Kansas, north of Strong City. The preserve protects a nationally significant example of the once vast tallgrass prairie ecosystem. Of the 400,000 square miles (1,000,000 km2) of tallgrass prairie that once covered the North American continent, less than 5% remains, primarily in the Flint Hills. Since 2009, the preserve has been home to the Tallgrass Prairie bison herd.
The tallgrass prairie is an ecosystem native to central North America. Historically, natural and anthropogenic fire, as well as grazing by large mammals provided periodic disturbances to these ecosystems, limiting the encroachment of trees, recycling soil nutrients, and facilitating seed dispersal and germination. Prior to widespread use of the steel plow, which enabled large scale conversion to agricultural land use, tallgrass prairies extended throughout the American Midwest and smaller portions of southern central Canada, from the transitional ecotones out of eastern North American forests, west to a climatic threshold based on precipitation and soils, to the southern reaches of the Flint Hills in Oklahoma, to a transition into forest in Manitoba.
An oak savanna is a type of savanna—or lightly forested grassland—where oaks are the dominant trees. The terms "oakery" or "woodlands" are also used commonly, though the former is more prevalent when referencing the Mediterranean area. These savannas were maintained historically through wildfires set by lightning, humans, grazing, low precipitation, and/or poor soil.
The Midewin National Tallgrass Prairie (MNTP) is a tallgrass prairie reserve and is preserved as United States National Grassland operated by the United States Forest Service. The first national tallgrass prairie ever designated in the U.S. and the largest conservation site in the Chicago Wilderness region, it is located on the site of the former Joliet Army Ammunition Plant between the towns of Elwood, Manhattan and Wilmington in northeastern Illinois. Since 2015, it has hosted a conservation herd of American bison to study their interaction with prairie restoration and conservation.
Wichita Mountains Wildlife Refuge, located in southwestern Oklahoma near Lawton, has protected unique wildlife habitats since 1901 and is the oldest managed wildlife facility in the United States Fish and Wildlife Service system. The refuge's location in the geologically unique Wichita Mountains and its areas of undisturbed mixed grass prairie make it an important conservation area. The Wichita Mountains are approximately 500 million years old. Measuring about 59,020 acres (238.8 km2), the refuge hosts a great diversity of species: 806 plant species, 240 species of birds, 36 fish, and 64 reptiles and amphibians are present.
The National Elk Refuge is a Wildlife Refuge located in Jackson Hole in the U.S. state of Wyoming. It was created in 1912 to protect habitat and provide sanctuary for one of the largest elk herds. With a total of 24,700 acres (10,000 ha), the refuge borders the town of Jackson, Wyoming, on the southwest, Bridger-Teton National Forest on the east and Grand Teton National Park on the north. It is home to an average of 7,500 elk each winter. The refuge is managed by the U.S. Fish and Wildlife Service, an agency of the U.S. Department of the Interior.
Prairie restoration is a conservation effort to restore prairie lands that were destroyed due to industrial, agricultural, commercial, or residential development. The primary aim is to return areas and ecosystems to their previous state before their depletion.
The Konza Prairie Biological Station is a 8,616-acre (3,487 ha) protected area of native tallgrass prairie in the Flint Hills of northeastern Kansas. "Konza" is an alternative name for the Kansa or Kaw Indians who inhabited this area until the mid-19th century. The Konza Prairie is owned by The Nature Conservancy and Kansas State University.
Glacial Ridge National Wildlife Refuge was created on October 12, 2004, the 545th National Wildlife Refuge in the United States. Its creation was the result of cooperation between at least 30 agencies or governmental entities. The creation of the refuge was spearheaded by The Nature Conservancy, and the initial endowment of 2,300 acres (9.3 km2) of land was donated by the Conservancy. In light of its planned final size of 37,756 acres (153 km2), it is described by the US Fish and Wildlife Service as "the largest tallgrass prairie and wetland restoration project in U.S. history."
Prairie State Park is a public recreation area encompassing nearly 4,000 acres (1,600 ha) of grasslands and woodlands in Barton County, Missouri. The state park preserves much of the few remaining acres of tallgrass prairie in the state. The park features hiking trails, camping for backpackers, and a nature center. Captive wild bison and elk roam the park. The bison herd contains about 100 individuals as of spring 2021.
Northern Tallgrass Prairie National Wildlife Refuge was established to provide a means of working with individuals, groups, private organizations, and government entities to permanently preserve a portion of the remaining remnant tracts of northern tallgrass prairie in Minnesota and Iowa. The United States Fish and Wildlife Service is acquiring remnant prairie tracts for the refuge in both easement and fee title interests from willing sellers.
The Windom Wetland Management District acquires and manages Waterfowl Production Areas, enforces wetland easements, and provides conservation assistance to landowners in 12 southwestern Minnesota counties. The landscape is dominated by intense, row-crop agriculture, which has led to the drainage of most wetlands and widespread water quality problems. Deteriorating drainage tile systems and the abundance of historic wetland basins provide unlimited opportunities for wetland restorations.
The Central tall grasslands are a prairie ecoregion of the Midwestern United States, part of the North American Great Plains.
American Prairie is a prairie-based nature reserve in Central Montana, United States, on a mixed grass prairie ecosystem with migration corridors and native wildlife. This wildlife conservation area is being developed as a private project of the American Prairie Foundation (APF). This independent non-profit organization aims to include over 3 million acres (12,000 km2) through a combination of both private and public lands.
The Maxwell Wildlife Refuge in McPherson County, Kansas consists of 2,574 acres (1,042 ha) of mostly mixed grass prairie. Bison and elk inhabit the refuge. The McPherson State Fishing Lake adjoins the refuge and adds another 260 acres (110 ha) of protected area, including a 46 acres (19 ha) lake.
Kankakee Sands is a 10,000-acre (4,000 ha) restored tallgrass prairie in Kankakee County, Illinois and Newton County, Indiana. It is managed by The Nature Conservancy staff and volunteers. The Efroymson Restoration at Kankakee Sands is 8,400 acres (3,400 ha) of prairies and wetlands connecting Willow Slough Fish and Wildlife Area, Beaver Lake Nature Preserve, Conrad Savanna Nature Preserve and Conrad Station Savanna. This creates over 20,000 acres (8,100 ha) of dry, mesic and wet sand prairies, sand blows, sedge meadows, wetlands, and black oak savannas.
The conservation of bison in North America is an ongoing, diverse effort to bring American bison back from the brink of extinction. Plains bison, a subspecies, are a keystone species in the North American Great Plains. Bison are a species of conservation concern in part because they suffered a severe population bottleneck at the end of the 19th century. The near extinction of the species during the 19th century unraveled fundamental ties between bison, grassland ecosystems, and indigenous peoples’ cultures and livelihoods. English speakers used the word buffalo for this animal when they arrived. Bison was used as the scientific term to distinguish them from the true buffalo. Buffalo is commonly used as it continues to hold cultural significance, particularly for Indigenous people.
