Mixed Grass Prairie
A mixed-grass prairie is an ecotone located between the tallgrass prairies and shortgrass prairies. The mixed-grass prairie is richer in botanical diversity than either the tall- or shortgrass prairie. The mixed-grass prairie occurs in the Central Great Plains (ecoregion), central plains portion of the Great Plains, varying in width from central Texas in the United States up into southeastern Manitoba, Alberta and Saskatchewan in the northern mixed grasslands of Canada.G.

Prairies
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 Romania, Ukraine, Russia, and Kazakhstan. Lands typically referred to as "prairie" (a French loan word) tend to be in North America. The term encompasses the lower and mid-latitude of the area referred to as the Interior Plains of Canada, the United States, and Mexico. It includes all of the Great Plains as well as the wetter, hillier land to the east. From west to east, generally the drier expanse of shortgrass prairie gives way to mixed grass prairie and ultimately the richer and wetter soils of the tallgrass prairie. In the U.S., the area is constituted by most or all of the states, from north to south, of Nor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wind Cave National Park
Wind Cave National Park is a national park of the United States located north of the town of Hot Springs in western South Dakota. Established on January 3, 1903 by President Theodore Roosevelt, it was the sixth national park in the U.S. and the first cave to be designated a national park anywhere in the world. The cave is notable for its calcite formations known as boxwork, as well as its frostwork. Approximately 95 percent of the world's discovered boxwork formations are found in Wind Cave. Wind Cave is one of the best known examples of a breathing cave. The cave is recognized as the densest cave system in the world, with the greatest passage volume per cubic mile. Wind Cave is the sixth longest cave in the world with of explored cave passageways () and the third longest cave in the United States, though it is only the second longest cave in Custer County, South Dakota behind Jewel Cave. Despite the close proximity, no connection has ever been found between Wind Cave an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sandhills (Nebraska)
The Sandhills, often written Sand Hills, is a region of mixed-grass prairie on grass-stabilized sand dunes in north-central Nebraska, covering just over one quarter of the state. The dunes were designated a National Natural Landmark in 1984. Geography The boundaries of the Sandhills are variously defined by different organizations. Depending on the definition, the region's area can be as small as 19,600 mi2 (50,760 km2) or as large as 23,600 mi2 (61,100 km2). Dunes in the Sandhills may exceed 330 ft (100 m) in height. The average elevation of the region gradually increases from about 1,800 ft (550 m) in the east to about 3,600 ft (1,100 m) in the west. The Sandhills sit atop the massive Ogallala Aquifer; thus both temporary and permanent shallow lakes are common in low-lying valleys between the grass-stabilized dunes prevalent in the Sandhills. The eastern and central sections of the region are drained by tributaries of the Loup River an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wichita Mountains Wildlife Refuge
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 , the refuge hosts a great diversity of species: 806 plant species, 240 species of birds, 36 fish, and 64 reptiles and amphibians are present. History The Wichita Forest Reserve was established by the United States General Land Office in Oklahoma on July 4, 1901, with . After the transfer of federal forests to the U.S. Forest Service in 1905, it became a National Forest on March 4, 1907, as Wichita National Forest. On June 4, 1936, the Wichita Forest designation was abolished and transferred to the Bureau of Biological ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drift Prairie
The Drift Prairie is a geographic region in the U.S. states of North Dakota and South Dakota. In North Dakota, the Drift Prairie is the transition zone between two zones. The gently rolling hills and shallow lakes were formed by glacial action, while the badlands to the west are characterized by the lack of this action, and the Red River Valley to the east was a lakebed. This distinction causes the area considered the Drift Prairie to overlap somewhat with the Missouri Plateau, another of North Dakota's distinct geographic regions, but the Drift Prairie also includes the Souris River basin. Prairie grasses and wheat grow there, making it a perfect place for ranchers. The prairie is filled with drift, a type of soil consisting of clay, sand, and gravel originating from glacial processes. In South Dakota, most of the eastern part of the state is covered by the Drift Prairie. The Missouri River cuts through the center of the state. To the east of the river are low hills and lake ...

Valentine National Wildlife Refuge
Valentine National Wildlife Refuge is located in the U.S. state of Nebraska and includes 19,131 acres (77.42 km2). The refuge protects a portion of the largest remaining area of tall and mid grass prairie in the United States. Development Collectively known as the sand hills region of Nebraska, the dunes were the result of the last ice age known as the Pinedale glaciation. During the Holocene glacial retreat the sand dunes that been deposited in their current location by the vast continental glaciers, were exposed and grasses eventually took over. Management The refuge is managed by the U.S. Fish and Wildlife Service and along with Fort Niobrara and John and Louise Seier National Wildlife Refuges, they form the Fort Niobrara National Wildlife Refuge Complex. In 1976, the Valentine National Wildlife Refuge was designated as a National Natural Landmark by the National Park Service. Natural features Numerous lakes and ponds are located on the refuge, fed by unde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Missouri Coteau
The Missouri Coteau, or Missouri Plateau, () is a large plateau that stretches along the eastern side of the valley of the Missouri River in central North Dakota and north-central South Dakota in the United States. In the Canadian provinces of Saskatchewan and Alberta this physiographic region is classified as the Uplands Missouri Coteau, which is a part of the Great Plains Province or Alberta Plateau Region, which extends across the southwest corner of the province of Saskatchewan as well as the southeast corner of the province of Alberta. Historically, in Canada the area was known as the Palliser's Triangle and regarded as an extension of the Great American Desert and unsuitable for agriculture and thus designated by Canadian geographer and explorer John Palliser. The terrain of the Missouri Coteau features low hummocky, undulating, rolling hills, potholes, and grasslands. Apart from being a geographical area, the Missouri Coteau also has a cultural connection to the people of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theodore Roosevelt National Park
Theodore Roosevelt National Park is a List of national parks of the United States, national park of the United States in the badlands of western North Dakota comprising three geographically separated areas. This park pays homage to the time that Theodore Roosevelt spent in the surrounding area and in the Dakota Territories before they were states. Roosevelt lived in the area after his mother and wife died hours apart on February 14, 1884. Theodore Roosevelt National Park is the only American national park named after a single person. The park covers of land in three sections: the North Unit, the South Unit, and the Elkhorn Ranch Unit. The Little Missouri River (North Dakota), Little Missouri River flows through all three units of the park. The Maah Daah Hey Trail connects all three units.

Central Plains Biosphere Reserve
The Central Plains Biosphere Reserve (established in 1976 and withdrawn in 2017) was a UNESCO Biosphere Reserve located in the western central Great Plains in north-central Colorado in the shortgrass prairie. The reserve encompasses the Central Plains Experimental Range (CPER) administered by the United States Department of Agriculture's Agricultural Research Service. History The Central Plains Experimental Range has a long history of research on shortgrass prairie ecosystems and the effects of range management practices. Several areas in the reserve were farmed and grazed for many years and are now embedded in a countryside of intense agriculture. In the Dust Bowl years of the mid 1930s, many farms and ranches of the western Great Plains were abandoned due to drought, overgrazing and soil blown from plowed fields. The U.S. Forest Service requested that the Central Plains Experimental Range be established to research improved management practices on fragile grasslands. The first ...
