full_context: Document 1: Tallgrass Prairie Preserve: The Tallgrass Prairie Preserve, located in Osage County, Oklahoma near Foraker, Oklahoma, is owned and managed by The Nature Conservancy. It is protected as the largest tract of remaining tallgrass prairie in the world. The preserve contains 39000 acre owned by the Conservancy and another 6000 acre leased in what was the original tallgrass region of the Great Plains that stretched from Texas to Manitoba.
Document 2: High Plains (United States): The High Plains are a subregion of the Great Plains mostly in the Western United States, but also partly in the Midwest states of Nebraska, Kansas, and South Dakota, generally encompassing the western part of the Great Plains before the region reaches the Rocky Mountains. The High Plains are located in southeastern Wyoming, southwestern South Dakota, western Nebraska, eastern Colorado, western Kansas, eastern New Mexico, western Oklahoma, and south of the Texas Panhandle. The southern region of the Western High Plains ecology region contains the geological formation known as Llano Estacado which can be seen from a short distance or from on satellite maps. From east to west, the High Plains rise in elevation from around 1160 ft to over 7800 ft .
Document 3: Tallgrass Prairie National Preserve: 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 km) of tallgrass prairie that once covered the North American continent, less than 4% remains, primarily in the Flint Hills. Since 2009, the preserve has been home to the growing Tallgrass Prairie bison herd.

Document 5: List of Native American actors: This is a list of Native American actors in the United States, including Alaskan Natives and American Indians. Native American identity is a complex and contested issue rooted in political sovereignty that pre-dates the creation of colonial nation states like the U.S. and Canada and persists into the 21st century recognized under international law by treaty. The Bureau of Indian Affairs defines Native American as having American Indian or Alaska Native ancestry. Legally, being Native American is defined as being enrolled in a federally recognized tribe or Alaskan village. Ethnologically, factors such as culture, history, language, religion, and familial kinships can influence Native American identity. All individuals on this list should have Native American ancestry. Historical figures might predate tribal enrollment practices and would be included based on ethnological tribal membership, while any contemporary individuals should either be enrolled members of federally recognized tribes or have cited Native American ancestry and be recognized as being Native American by their respective tribes(s). Contemporary unenrolled individuals are listed as being of descent from a tribe.
Document 6: Little People of the Pryor Mountains: The Little People of the Pryor Mountains (known as Nirumbee or Awwakkulé in the Crow language) are a race of ferocious dwarves in the folklore of the Crow Nation, a Native American tribe. The Little People were also seen as imparting spiritual wisdom, and played a major role in shaping the destiny of the Crow People through the dreams of the legendary Crow chief, Plenty Coups.
Document 7: Native American religion: Native American religions are the spiritual practices of the indigenous peoples of the Americas. This article focuses on Native North Americans. Traditional Native American ceremonial ways can vary widely, and are based on the differing histories and beliefs of individual tribes, clans and bands. Early European explorers describe individual Native American tribes and even small bands as each having their own religious practices. Theology may be monotheistic, polytheistic, henotheistic, animistic, or some combination thereof. Traditional beliefs are usually passed down in the forms of oral histories, stories, allegories and principles, and rely on face to face teaching in one's family and community.
Document 8: Great Plains: The Great Plains (sometimes simply "the Plains") is the broad expanse of flat land (a plain), much of it covered in prairie, steppe and grassland, that lies west of the Mississippi River tallgrass prairie states and east of the Rocky Mountains in the United States and Canada. It embraces
Document 9: Osage Plains: The Osage Plains are a physiographic section of the larger Central Lowland province, which in turn is part of the larger Interior Plains physiographic division. The area is sometimes called the Lower Plains, North Central Plains, and the Rolling Plains. The Osage Plains, covering west-central Missouri, the southeastern third of Kansas, most of central Oklahoma, and extending into north-central Texas, is the southernmost of three tallgrass prairie physiographic areas. It grades into savanna and woodland to the east and south, and into shorter mixed-grass prairie to the west. The Osage Plains consist of three subregions. The Osage Plains proper occupy the northeast segment. Although sharply demarcated from the Ozark uplift, the Plains are nonetheless a transitional area across which the boundary between prairie and woodland has shifted over time. In the central portion of the physiographic area lies the second subregion, the Flint Hills, commonly called "The Osage" in Oklahoma. This large remnant core of native tallgrass prairie is a rocky rolling terrain that run from north to south across Kansas and extends into Oklahoma. To the west and south of these hills are the Blackland Prairies and Cross Timbers. This vegetatively complex region of intermixed prairie and scrubby juniper-mesquite woodland extends into north-central Texas. Bluestem prairies and oak-dominated savannas and woodlands characterize the natural vegetation in the Cross Timbers. Much of the area has been converted to agriculture, although expanses of oak forest and woodland are still scattered throughout the eastern portion of the subregion.
Document 10: Contrary (social role): A Contrary was a member of a Native North American tribal group who adopted behavior that was deliberately the opposite of other tribal members. The Contraries were found among the historical Amerindian tribes of the Great Plains. They were a small number of individuals loosely organized into a cult that was devoted to the practice of contrary behavior.
Document 11: Native Americans in the United States: In the United States of America, Native Americans (also known as American Indians, Indigenous Americans or simply Indians; see §Terminology differences) are people who belong to one of the over 500 distinct Native American tribes that survive intact today as partially sovereign nations within the country's modern boundaries. These tribes and bands are descended from the pre-Columbian indigenous population of North America.
Document 12: Depopulation of the Great Plains: The depopulation of the Great Plains refers to the large-scale migration of people from rural areas of the Great Plains of the United States to more urban areas and to the east and west coasts during the 20th century. This phenomenon of rural-to-urban migration has occurred to some degree in most areas of the United States, but has been especially pronounced in the Great Plains states, including Texas, Oklahoma, Kansas, Nebraska, South Dakota, North Dakota, Montana, Wyoming, Colorado, and New Mexico where many counties have lost more than 60 percent of their former populations.
Document 13: Native Americans in popular culture: The portrayal of Native Americans in popular culture has oscillated between the fascination with the noble savage who lives in harmony with nature, and the stereotype of the uncivilized "bad guys" in the traditional Western genre. The common depiction of Native Americans and the relationship between the white settlers has changed significantly throughout history. In modern times, Native Americans live completely different lives than they once did, yet retain most of their cultural beliefs and traditional practices.
Document 14: Northern short grasslands: The Northern short grasslands is one of 867 terrestrial ecoregions defined by the World Wide Fund for Nature. This ecoregion includes parts of the Canadian provinces of Alberta and Saskatchewan, and the American Great Plains states of Montana, North Dakota, Wyoming, South Dakota and Nebraska. The United States Environmental Protection Agency (EPA) further breaks this ecoregion into the Northwestern Glaciated Plains and Northwestern Great Plains.
Document 15: Plains Indians: Plains Indians, Interior Plains Indians or Indigenous people of the Great Plains and Canadian Prairies are the Native American tribes and First Nation band governments who have traditionally lived on the greater Interior Plains (i.e. the Great Plains and the Canadian Prairies) in North America. Their historic nomadic culture and development of equestrian culture and resistance to domination by the government and military forces of Canada and the United States have made the Plains Indian culture groups an archetype in literature and art for American Indians everywhere.
