White River National Wildlife Refuge
The White River National Wildlife Refuge (officially Dale Bumpers White River National Wildlife Refuge) is a wildlife refuge located in Desha, Monroe, Phillips, and Arkansas counties in the U.S. state of Arkansas. The refuge is managed by the United States Fish and Wildlife Service. White River NWR borders on Cache River National Wildlife Refuge at its northern boundary. In 1974, the White River Sugarberry Natural Area was designated as a National Natural Landmark by the National Park Service. In 2013, the FWS proposed the gradual expansion of the refuge up to a maximum of . Description White River National Wildlife Refuge was created in 1935. The refuge is wide and encompassing of the lower of the White River. It also includes of the Arkansas Post Canal which is part of the Army Corps of Engineers' McClellan-Kerr Navigation System on the Arkansas River. This refuge has the largest concentration of wintering mallard ducks in the Mississippi Flyway. It also has large c ...

Arkansas
Arkansas ( ) is a landlocked state in the South Central United States. It is bordered by Missouri to the north, Tennessee and Mississippi to the east, Louisiana to the south, and Texas and Oklahoma to the west. Its name is from the Osage language, a Dhegiha Siouan language, and referred to their relatives, the Quapaw people. The state's diverse geography ranges from the mountainous regions of the Ozark and Ouachita Mountains, which make up the U.S. Interior Highlands, to the densely forested land in the south known as the Arkansas Timberlands, to the eastern lowlands along the Mississippi River and the Arkansas Delta. Arkansas is the 29th largest by area and the 34th most populous state, with a population of just over 3 million at the 2020 census. The capital and most populous city is Little Rock, in the central part of the state, a hub for transportation, business, culture, and government. The northwestern corner of the state, including the Fayetteville–Springdaleâ ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Mississippi Flyway
The Mississippi Flyway is a bird migration route that generally follows the Mississippi, Missouri, and Lower Ohio Rivers in the United States across the western Great Lakes to the Mackenzie River and Hudson Bay in Canada. The main endpoints of the flyway include central Canada and the region surrounding the Gulf of Mexico. The migration route tends to narrow considerably in the lower Mississippi River valley in the states of Missouri, Arkansas, Mississippi, and Louisiana, which accounts for the high number of bird species found in those areas. Some birds use this flyway to migrate from the Arctic Ocean to Patagonia. Typically birds use this route because no mountains or ridges of hills block the path over its entire extent. Good sources of water, food, and cover exist over its entire length. About 40% of all North American migrating waterfowl and shorebirds use this route. The other primary migration routes for North American birds include the Atlantic, Central and Pacific Fl ...

Green Ash
''Fraxinus pennsylvanica'', the green ash or red ash, is a species of ash native to eastern and central North America, from Nova Scotia west to southeastern Alberta and eastern Colorado, south to northern Florida, and southwest to Oklahoma and eastern Texas. It has spread and become naturalized in much of the western United States and also in Europe from Spain to Russia. Other names more rarely used include downy ash, swamp ash and water ash. Description ''Fraxinus pennsylvanica'' is a medium-sized deciduous tree reaching (rarely to ) tall with a trunk up to in diameter. The bark is smooth and gray on young trees, becoming thick and fissured with age. The winter buds are reddish-brown, with a velvety texture. The leaves are long, oppositely arranged, pinnately compound with seven to nine (occasionally five or eleven) leaflets, these (rarely ) long and broad, with serrated margins and short but distinct, downy petiolules a few millimeters long. They are green both above ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

American Elm
''Ulmus americana'', generally known as the American elm or, less commonly, as the white elm or water elm, is a species of elm native to eastern North America, naturally occurring from Nova Scotia west to Alberta and Montana, and south to Florida and central Texas. The American elm is an extremely hardy tree that can withstand winter temperatures as low as −42 ° C (−44 ° F). Trees in areas unaffected by Dutch elm disease (DED) can live for several hundred years. A prime example of the species was the Sauble Elm, which grew beside the banks of the Sauble River in Ontario, Canada, to a height of 43 m (140 ft), with a d.b.h of 196 cm (6.43 ft) before succumbing to DED; when it was felled in 1968, a tree-ring count established that it had germinated in 1701. For over 80 years, ''U. americana'' had been identified as a tetraploid, i.e. having double the usual number of chromosomes, making it unique within the genus. However, a study published in 2011 by t ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Sugarberry
''Celtis laevigata'' is a medium-sized tree native to North America. Common names include sugarberry, Southern hackberry, or in the southern U.S. sugar hackberry or just hackberry. Sugarberry is easily confused with common hackberry ('' C. occidentalis'') where the range overlaps. Sugarberry has narrower leaves with mostly smooth margins, the berries are juicier and sweeter, while the bark is less corky. The species can also be distinguished by habitat: where the ranges overlap, common hackberry occurs primarily in upland areas, whereas sugarberry occurs mainly in bottomland areas. Sugarberry's range extends from the Eastern United States west to Texas and south to northeastern Mexico. It is also found on the island of Bermuda. Ecology Sugarberry occurs primarily along streams and in moist soils on floodplains. Its sweetish fruit is eaten by birds and rodents, helping to disperse the seeds. The leaves are eaten by a number of insects, for example caterpillars of the Io mot ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Willow Oak
''Quercus phellos'', the willow oak, is a North American species of a deciduous tree in the red oak group of oaks. It is native to the south-central and eastern United States. Description It is a medium-sized tree growing to tall (exceptionally to ), with a trunk up to in diameter (exceptionally ). It is distinguished from most other oaks by its leaves, which are shaped like willow leaves, long and broad with an entire (untoothed and unlobed) margin; they are bright green above, paler beneath, usually hairless but sometimes downy beneath. The fruit is an acorn, long, and almost as wide as long, with a shallow cup; it is one of the most prolific producers of acorns. The tree starts acorn production around 15 years of age, earlier than many oak species. Willow oaks can grow moderately fast (height growth up to a year), and tend to be conic to oblong when young, rounding out and gaining girth at maturity (i.e. more than 50 years).

Nuttall's Oak
''Quercus texana'', commonly known as Nuttall's oak, is a fast-growing, large deciduous oak tree. It is a tree growing up to 25 meters (83 feet) tall, with dark brown bark. It has leaves with sharp pointed lobes somewhat similar to those of the Georgia oak (''Q. georgiana'') and pin oak (''Q. palustris''). It is fast-growing and usually has a pleasing red color in autumn, much more reliably so than the pin oak. This species was for years erroneously called ''Quercus nuttallii'', but it is now known as ''Q. texana''; this has created much confusion with Texas red oak, which was known as ''Q. texana'' but is now known as ''Q. buckleyi''. It is native to the south-central United States primarily in the lower Mississippi River Valley in Louisiana, Arkansas, Mississippi, Alabama, and western Tennessee. There are additional populations in eastern Texas, southeastern Oklahoma, southeastern Missouri, far western Kentucky, and the southernmost tip of Illin ...

American Sweetgum
American sweetgum (''Liquidambar styraciflua''), also known as American storax, hazel pine, bilsted, redgum, satin-walnut, star-leaved gum, alligatorwood, or simply sweetgum, is a deciduous tree in the genus ''Liquidambar'' native to warm temperate areas of eastern North America and tropical montane regions of Mexico and Central America. Sweetgum is one of the main valuable forest trees in the southeastern United States, and is a popular ornamental tree in temperate climates. It is recognizable by the combination of its five-pointed star-shaped leaves (similar to maple leaves) and its hard, spiked fruits. It is currently classified in the plant family Altingiaceae, but was formerly considered a member of the Hamamelidaceae. Names This plant's genus name ''Liquidambar'' was first given by Linnaeus in 1753 from the Latin ('fluid') and the Arabic ('amber'), in allusion to the fragrant terebinthine juice or gum which exudes from the tree. Its specific epithet ''styraciflua'' is an ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Old-growth
An old-growth forestalso termed primary forest, virgin forest, late seral forest, primeval forest, or first-growth forestis a forest that has attained great age without significant disturbance, and thereby exhibits unique ecological features, and might be classified as a climax community. The Food and Agriculture Organization of the United Nations defines primary forests as naturally regenerated forests of native tree species where there are no clearly visible indications of human activity and the ecological processes are not significantly disturbed. More than one-third (34 percent) of the world's forests are primary forests. Old-growth features include diverse tree-related structures that provide diverse wildlife habitat that increases the biodiversity of the forested ecosystem. Virgin or first-growth forests are old-growth forests that have never been logged. The concept of diverse tree structure includes multi-layered canopies and canopy gaps, greatly varying tree height ...

Mississippi Lowland Forests
The Mississippi lowland forests are a temperate broadleaf and mixed forest ecoregion in the eastern United States, covering an area of . Setting Located on the Mississippi Alluvial Plain from Louisiana north to the southern edge of Illinois, the original forest cover of the Mississippi lowland forests was primarily bottomland hardwood forests, often subject to seasonal flooding which dictates the growth rate and composition. The forests historically occupied over 10,000,000 hectares of thick well-established forest of cypress (''Taxodium'' spp.), hickory, oak and cedars similar to that found in the Middle Atlantic Coastal Forests region. However nearly all the original forest along the Mississippi has now been cleared. The Mississippi floodplain is distinct from the surrounding countryside which is higher and drier. Flora The remaining woodlands are a mixture of oak, hickory and pine along with a rich mixture of other trees including bald cypress (''Taxodium distichum''), water ...

Ivory-billed Woodpecker
The ivory-billed woodpecker (''Campephilus principalis'') is a possibly extinct woodpecker that is native to the bottomland hardwood forests and temperate coniferous forests of the Southern United States and Cuba. Habitat destruction and hunting have reduced populations so thoroughly that the species is listed by the International Union for Conservation of Nature (IUCN) on its IUCN Red List, Red List as critically endangered, and by the American Birding Association as "definitely or probably extinct". The last universally accepted sighting of an American ivory-billed woodpecker occurred in Louisiana in 1944, and the last universally accepted sighting of a Cuban ivory-billed woodpecker occurred in 1987, after the bird's rediscovery there the prior year. Sporadic reports of sightings and other evidence of the persistence of the species have continued since then. The bird's preferred diet consists of large beetle larvae, particularly wood-boring Cerambycidae beetles, supplemented by ...

American Black Bear
The American black bear (''Ursus americanus''), also called simply a black bear or sometimes a baribal, is a medium-sized bear endemic to North America. It is the continent's smallest and most widely distributed bear species. American black bears are omnivores, with their diets varying greatly depending on season and location. They typically live in largely forested areas, but will leave forests in search of food, and are sometimes attracted to human communities due to the immediate availability of food. The International Union for Conservation of Nature (IUCN) lists the American black bear as a least-concern species, due to its widespread distribution and a large population estimated to be twice that of all other bear species combined. Along with the brown bear (''Ursus arctos''), it is one of only two modern bear species not considered by the IUCN to be globally threatened with extinction. Taxonomy and evolution Despite living in North America, American black bears are not ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
