Middle Atlantic Coastal Forests
The Middle Atlantic coastal forests are a temperate coniferous forest mixed with patches of evergreen broadleaved forests (closer to the Atlantic coast) along the coast of the southeastern United States. Setting The Middle Atlantic coastal forests stretch along the Southern Atlantic coast of the United States from extreme South Jersey south to the Georgia coast. They cover the lower Atlantic coastal plain and are bordered on the west by the Southeastern mixed forests. The habitats of the ecoregion are constantly modified by natural processes. The bottomlands, coastal plains, and maritime areas are vulnerable to tropical cyclones and floods. The drier areas with porous sandy soils are susceptible to fires and drought. Fire return intervals of 1 to 3 years favor herbaceous plants; longer intervals favor dense shrubs, to broadleaved evergreen trees. Climate This ecoregion has a humid subtropical climate with hot summers and mild winters, and with the heaviest precipitation conce ...

Congaree National Park
Congaree National Park is a national park of the United States in central South Carolina, 18 miles southeast of the state capital, Columbia. The park preserves the largest tract of old growth bottomland hardwood forest left in the United States. The lush trees growing in its floodplain forest are some of the tallest in the eastern United States, forming one of the highest temperate deciduous forest canopies remaining in the world. The Congaree River flows through the park. About are designated as a wilderness area. The park received its official designation in 2003 as the culmination of a grassroots campaign that began in 1969. With 145,929 visitors in 2018, it ranks as the United States' 10th-least visited national park, just behind Nevada's Great Basin National Park. Park history Pre-park Resource extraction on the Congaree River centered on cypress logging from 1898 when the ''Santee River Cypress Logging Company'' began to operate in the area of what is now the park ...

Southeastern United States
The Southeastern United States, also known as the American Southeast or simply the Southeast, is a geographical List of regions in the United States, region of the United States located in the eastern portion of the Southern United States and the southern portion of the East Coast of the United States, Eastern United States. The region includes a core of states that reaches north to Maryland and West Virginia, bordering the Ohio River and Mason–Dixon line, and stretches west to Arkansas and Louisiana. There is no official Federal government of the United States, U.S. government definition for the region, and it is defined variably among agencies and organizations. History The history of the present-day Southeastern United States dates to the dawn of civilization in approximately 11,000 BC or 13,000 BC. The earliest artifacts from the region were from the Clovis culture. Prior to the arrival of Colonial history of the United States, European colonialists, Native Americans in ...

Quercus Stellata
''Quercus stellata'', the post oak or iron oak, is a North American species of oak in the white oak section. It is a slow-growing oak that lives in dry areas on the edges of fields, tops of ridges, and also grows in poor soils, and is resistant to rot, fire, and drought. Interbreeding occurs among white oaks, thus many hybrid species combinations occur. It is identifiable by the rounded cross-like shape formed by the leaf lobes and hairy underside of the leaves. Taxonomy The specific epithet ''stellata'' is Latin for "star"; it is named this because the trichome hairs on the bottom of the leaves are stellate or star-shaped. Several variants of ''Q. stellata'' were named by American botanist Charles Sprague Sargent. The variety most recognised by the United States Forest Service is ''Q. stellata'' var. ''paludosa'' Sarg (delta post oak).Stransky, John J. "Quercus stellata Wangenh.--post oak.''Silvics of North America'' 2(1990): 738–743. Varieties Varieties inc ...

Quercus Laevis
''Quercus laevis'', the turkey oak, is a member of the red oak group of oaks. It is native to the southeastern United States. The name turkey oak derives from the resemblance of the leaves to a turkey's foot. A Turkish and southern European species '' Quercus cerris'' is also commonly referred to as Turkey oak, so ''Quercus laevis'' is sometimes referred to as American turkey oak to distinguish it from the European species. Description ''Quercus laevis'' is a small tree, sometimes shrubby, typically only tall, though occasionally reaching . The leaves are variable in size, mostly long but occasionally just or as much as long. They have 3–7 slender lobes, deeply incised between the lobes, each lobe with 1–3 bristle teeth at the tip. The leaves turn red in Autumn. The acorns are about long, and, like other red oaks, take 18 months to mature. Distribution and habitat Turkey oak occurs on the coastal plain from Virginia south to southwestern Florida, and west to so ...

Hardwood
Hardwood is wood from Flowering plant, angiosperm trees. These are usually found in broad-leaved temperate and tropical forests. In temperate and boreal ecosystem, boreal latitudes they are mostly deciduous, but in tropics and subtropics mostly evergreen. Hardwood (which comes from angiosperm trees) contrasts with softwood (which is from gymnosperm trees). Characteristics Hardwoods are produced by Flowering plant, angiosperm trees that reproduce by flowers, and have broad leaves. Many species are deciduous. Those of temperate regions lose their leaves every autumn as temperatures fall and are dormant in the winter, but those of tropical regions may shed their leaves in response to seasonal or sporadic periods of drought. Hardwood from deciduous species, such as oak, normally shows annual dendrochronology, growth rings, but these may be absent in some tropical timber, tropical hardwoods. Hardwoods have a more complex structure than softwoods and are often much slower growing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pinus Echinata
The shortleaf pine or ''Pinus echinata'' is a species of coniferous tree endemic to the United States. The shortleaf pine is sometimes referred to as the "old field", "spruce", "rosemary", "yellow", "two-leaf" and "heart" pine. The common name "shortleaf pine" may refer to other species like loblolly pine (''Pinus taeda''), based on a custom in the Southeastern United States to only refer to pines as either "long-leaf" or "short-leaf". However, ''P. echinata'' can be distinguished from other pines by examining its short leaves and small cones. Description The tree is variable in form, sometimes straight, sometimes crooked, with an irregular crown. The tree reaches heights of . In areas that have optimal growing conditions, the height reached is between . The trunk diameter ranges between and averages between . The leaves are needle-like, in fascicles (bundles) of two and three mixed together, and from long. The cones are long, with thin scales with a transverse keel and a ...

Pinus Taeda
''Pinus taeda'', commonly known as loblolly pine, is one of several pines native to the Southeastern United States, from East Texas to Florida, and north to southern New Jersey. The wood industry classifies the species as a southern yellow pine. U.S. Forest Service surveys found that loblolly pine is the second-most common species of tree in the United States, after red maple. For its timber, the pine species is regarded as the most commercially important tree in the Southeastern U.S. The common name loblolly is given because the pine species is found mostly in lowlands and swampy areas. Loblolly pine is the first among over 100 species of ''Pinus'' to have its complete genome sequenced. As of March 2014, it was the organism having the largest sequenced genome size. Its genome, with 22 billion base pairs, is seven times larger than that of humans. As of 2018, assembly of the axolotl genome (32Gb) displaced loblolly pine as the largest assembled genome. The loblolly pine was s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pinus Palustris
The longleaf pine (''Pinus palustris'') is a pine species native to the Southeastern United States, found along the coastal plain from East Texas to southern Virginia, extending into northern and central Florida. In this area it is also known as "yellow pine" or "long leaf yellow pine", although it is properly just one out of a number of species termed yellow pine. It reaches a height of and a diameter of . In the past, before extensive logging, they reportedly grew to with a diameter of . The tree is a cultural symbol of the Southern United States, being the official state tree of Alabama. This particular species is one of the eight pine tree species that falls under the "Pine" designation as the state tree of North Carolina. Description The bark is thick, reddish-brown, and scaly. The leaves are dark green and needle-like, and occur in bundles of mainly three, sometimes two or four, especially in seedlings. They often are twisted and in length. A local race of ''P. palu ...

Hammock (ecology)
Hammock is a term used in the southeastern United States for stands of trees, usually hardwood, that form an ecological island in a contrasting ecosystem. Hammocks grow on elevated areas, often just a few inches high, surrounded by wetlands that are too wet to support them. The term ''hammock'' is also applied to stands of hardwood trees growing on slopes between wetlands and drier uplands supporting a mixed or coniferous forest. Types of hammocks found in the United States include tropical hardwood hammocks, temperate hardwood hammocks, and maritime or coastal hammocks. Hammocks are also often classified as hydric (wet soil), mesic (moist soil) or xeric (dry soil). The types are not exclusive, but often grade into each other. Unlike many ecosystems of the coastal plain of the southeastern United States, hammocks are not tolerant of fire. Hammocks tend to occur in locations where fire is not common, or where there is some protection from fire in neighboring ecosystems. Hammocks ...

Humid Subtropical Climate
A humid subtropical climate is a subtropical -temperate climate type, characterized by long and hot summers, and cool to mild winters. These climates normally lie on the southeast side of all continents (except Antarctica), generally between latitudes 25° and 40° and are located poleward from adjacent tropical climates, and equatorward from either humid continental (in North America and Asia) or oceanic climates (in other continents). It is also known as warm temperate climate in some climate classifications. Under the Köppen climate classification, ''Cfa'' and ''Cwa'' climates are either described as humid subtropical climates or warm temperate climates. This climate features mean temperature in the coldest month between (or ) and and mean temperature in the warmest month or higher. However, while some climatologists have opted to describe this climate type as a "humid subtropical climate", Köppen himself never used this term. The humid subtropical climate classific ...

Herbaceous Plant
Herbaceous plants are vascular plants that have no persistent woody stems above ground. This broad category of plants includes many perennials, and nearly all annuals and biennials. Definitions of "herb" and "herbaceous" The fourth edition of the '' Shorter Oxford English Dictionary'' defines "herb" as: # "A plant whose stem does not become woody and persistent (as in a tree or shrub) but remains soft and succulent, and dies (completely or down to the root) after flowering"; # "A (freq. aromatic) plant used for flavouring or scent, in medicine, etc.". (See: Herb) The same dictionary defines "herbaceous" as: # "Of the nature of a herb; esp. not forming a woody stem but dying down to the root each year"; # "BOTANY Resembling a leaf in colour or texture. Opp. scarious". Botanical sources differ from each other on the definition of "herb". For instance, the Hunt Institute for Botanical Documentation includes the condition "when persisting over more than one growing season, th ...

Tropical Cyclones
A tropical cyclone is a rapidly rotating storm system with a low-pressure area, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls. Depending on its location and strength, a tropical cyclone is called a hurricane (), typhoon (), tropical storm, cyclonic storm, tropical depression, or simply cyclone. A hurricane is a strong tropical cyclone that occurs in the Atlantic Ocean or northeastern Pacific Ocean. A typhoon is the same thing which occurs in the northwestern Pacific Ocean. In the Indian Ocean and South Pacific, comparable storms are referred to as "tropical cyclones". In modern times, on average around 80 to 90 named tropical cyclones form each year around the world, over half of which develop hurricane-force winds of or more. Tropical cyclones typically form over large bodies of relatively warm water. They derive their energy through the evaporation of water from the ocean s ...
