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 ecological diversity than either the tall- or shortgrass prairie. The mixed-grass prairie occurs in the 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 Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by tot ....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 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. In the U.S., the area is constituted by most or all of the states of North Dakota, South Dakota, Nebraska, Kansas, and Oklahoma, and sizable parts of the states of Montana, Wyoming, Colorado, New Mexico, Texas, Missouri, Iowa, Illinois, Indiana, Wisconsin, and western and southern Minnesota.

Wind Cave National Park
Wind Cave National Park is an American national park 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. The cave is recognized as the densest cave system in the world, with the greatest passage volume per cubic mile. Wind Cave is the seventh longest cave in the world with of explored cave passageways () and the third longest cave in the United States. Above ground, the park includes the largest remaining natural mixed-grass prairie in the United States. Origin of name The passages in the park are said to "breathe" as air continually moves into or out of them, equalizing the atmospheric pressure o ...

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 Wichitas 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 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 November 27, 1936, the forest was abolished and transferred to the Bureau of Biological Survey, a precursor to the Fish and Wil ...

Drift Prairie
The Drift Prairie is a geographic region 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 Glaciation, 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 lake bed. This distinction causes the area considered as 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. Drift is soil consisting of clay, sand, and gravel. In South Dakota, most of the eastern 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 lakes formed by glaciers referred to as the Drift Prairie. The a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 end 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 underg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Missouri Coteau
The Missouri Coteau, or Missouri Plateau, (french: Coteau du Missouri) 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 co ...

Theodore Roosevelt National Park
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. The park covers of land in three sections: the North Unit, the South Unit, and the Elkhorn Ranch Unit. The Little Missouri River flows through all three units of the park. The Maah Daah Hey Trail connects all three units. The park's larger South Unit lies alongside Interstate 94 near Medora, North Dakota. The smaller North Unit is situated about 80 mi (130 km) north of the South Unit, and Roosevelt's Elkhorn Ranch is located between the North and South units. Both main units of the park have scenic drives, approximately of foot and horse trails, wildlife viewing, and back country hiking and camping. The park received 850,000 recreational visitors in 2021.

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 fi ...
