Sugarloaf Mountains-Midland Peak Natural Area
The Sugarloaf Mountains-Midland Peak Natural Area is an upland area of connected mountain ridges in the Arkansas Valley adjacent to the Arkansas–Oklahoma border and south of Fort Smith, Arkansas. This Natural Area is one part of a mosaic of high forest, savanna, and glade in the transition zone between the temperate broadleaf and mixed forests of the Eastern United States and the tallgrass prairie of the southern Great Plains. Sugarloaf Mountain (officially, East Midland Peak) has the largest identified population of the endangered maple-leaf oak as well as populations of the endangered Ouachita Mountain leadplant, ''Elymus churchii Elymus may refer to: * ''Elymus'' (plant), a genus of grasses * Elymus (mythology), the mythical ancestor of the Elymians * A man killed by Gorge (mythology) In Greek mythology, Gorge( grc, Γόργη, comes from the adjective ''gorgos,'' "terri ...''

Arkansas Valley (ecoregion)
The Arkansas Valley is a Level III ecoregion designated by the Environmental Protection Agency (EPA) in the U.S. states of Arkansas and Oklahoma. It parallels the Arkansas River between the flat plains of western Oklahoma and the Arkansas Delta, dividing the Ozarks and the Ouachita Mountains with the broad valleys created by the river's floodplain, occasionally interrupted by low hills, scattered ridges, and mountains. In Arkansas, the region is often known as the Arkansas River Valley (or just River Valley), especially when describing the history and culture of the region. Arkansas Valley is a synclinal and alluvial valley lying between the Ozark Highlands and the Ouachita Mountains. The Arkansas Valley is, characteristically, diverse and transitional. It generally coincides with the Arkoma Basin, an oil and gas province, that developed as sand and mud were deposited in a depression north of the rising Ouachita Mountains during the Mississippian and Pennsylvanian eras.

Tallgrass Prairie
The tallgrass prairie is an ecosystem native to central North America. Historically, natural and anthropogenic fire, as well as grazing by large mammals (primarily bison) 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. They were characteristically found in the central forest-grasslands transition, the central tall grasslands, the upper Midwest forest-savanna transition, and the northern tall grasslands ecoregions. They flou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Plains
The Great Plains (french: Grandes Plaines), sometimes simply "the Plains", is a broad expanse of flatland in North America. It is located west of the Mississippi River and east of the Rocky Mountains, much of it covered in prairie, steppe, and grassland. It is the southern and main part of the Interior Plains, which also include the tallgrass prairie between the Great Lakes and Appalachian Plateau, and the Taiga Plains and Boreal Plains ecozones in Northern Canada. The term Western Plains is used to describe the ecoregion of the Great Plains, or alternatively the western portion of the Great Plains. The Great Plains lies across both Central United States and Western Canada, encompassing: * The entirety of the U.S. states of Kansas, Nebraska, North Dakota and South Dakota; * Parts of the U.S. states of Colorado, Iowa, Minnesota, Missouri, Montana, New Mexico, Oklahoma, Texas and Wyoming; * The southern portions of the Canadian provinces of Alberta, Saska ...

Quercus Acerifolia
''Quercus acerifolia'' (also called maple-leaf oak) is a rare North American species of oak in the red oak section of ''Quercus'' (known as ''Lobatae''). It is endemic to just four locations within the Ouachita Mountains of the State of Arkansas. The tree sometimes reaches a height of 15 meters (50 feet). The venation of the leaves shows them to be technically pinnately five-lobed but with the two middle lobes larger than the other three. This makes the leaves appear palmately lobed at first glance, similar to many maple leaves. The epithet ''acerifolia'' means "maple-leaved." The species is threatened by habitat loss Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby ... throughout its fragmented range. Groves of the tree are under cultivation in several locations, notably Steph ...
