The Piney Woods is a temperate coniferous forest terrestrial ecoregion in the Southern United States covering 54,400 square miles (141,000 km2) of East Texas, southern Arkansas, western Louisiana, and southeastern Oklahoma. These coniferous forests are dominated by several species of pine as well as hardwoods including hickory and oak. Historically the most dense part of this forest region was the Big Thicket though the lumber industry dramatically reduced the forest concentration in this area and throughout the Piney Woods during the 19th and 20th centuries. The World Wide Fund for Nature considers the Piney Woods to be one of the critically endangered ecoregions of the United States. The United States Environmental Protection Agency (EPA) defines most of this ecoregion as the South Central Plains.
Fernbank Museum of Natural History, in Atlanta, Georgia, is a museum that presents exhibitions and programming about natural history. Fernbank Museum has a number of permanent exhibitions and regularly hosts temporary exhibitions in its expansive facility, designed by Graham Gund Architects. Giants of the Mesozoic, on display in the atrium of Fernbank Museum, features a 123-foot (37 m) long Argentinosaurus, the largest dinosaur ever classified; as well as a Giganotosaurus. The permanent exhibition, A Walk Through Time in Georgia, tells the twofold story of Georgia's natural history and the development of the planet. Fernbank Museum has won several national and international awards for one of its newest permanent exhibitions, Fernbank NatureQuest, an immersive, interactive exhibition for children that was designed and produced by Thinkwell Group. The awards NatureQuest has won include the 2012 Thea Award for Outstanding Achievement for a Museum Exhibit and the 2011 Bronze Award for Best Museum Environment from Event Design. The nearby Fernbank Science Center is a separate organization operated by the DeKalb County Board of Education and is not affiliated with Fernbank Museum of Natural History.
The Big Thicket is the name given to a somewhat imprecise region of a heavily forested area of Southeast Texas in the United States. This area represents a portion of the mixed pine-hardwood forests or "Piney Woods" of the Southeast US. The National Park Service established the Big Thicket National Preserve (BTNP) within the region in 1974 and it is recognized as a biosphere reserve by UNESCO. Although the diversity of animals in the area is high for a temperate zone with over 500 vertebrates, it is the complex mosaic of ecosystems and plant diversity that is particularly remarkable. Biologists have identified at least eight, and up to eleven, ecosystems in the Big Thicket area. More than 160 species of trees and shrubs, 800 herbs and vines, and 340 types of grasses are known to occur in the Big Thicket, and estimates as high as over 1000 flowering plant species and 200 trees and shrubs have been made, plus ferns, carnivorous plants, and more. The Big Thicket has historically been the most dense forest region in Texas.
The Texas Blackland Prairies are a temperate grassland ecoregion located in Texas that runs roughly 300 miles (480 km) from the Red River in North Texas to San Antonio in the south. The prairie was named after its rich, dark soil. Less than 1% of the original Blackland prairie vegetation remains, scattered across Texas in parcels.
Originally mapped in Cecil County, Maryland in 1899, more than 10 million acres (40,000 km2) of the Cecil soil series are now mapped in the Piedmont region of the southeastern United States. It extends from Virginia through North Carolina, South Carolina, Georgia and Alabama, with the typic Cecil pedon actually located in Franklin County, NC.
The Red Hills or Tallahassee Hills is a region of gently rolling hills in the southeastern United States. It is a geomorphic region and an ecoregion.
The mud snake is a species of nonvenomous, semiaquatic, colubrid snake endemic to the southeastern United States.
Carya tomentosa, commonly known as mockernut hickory, mockernut, white hickory, whiteheart hickory, hognut, bullnut, is a species of tree in the walnut family Juglandaceae. The most abundant of the hickories, and common in the eastern half of the United States, it is long lived, sometimes reaching the age of 500 years. A straight-growing hickory, a high percentage of its wood is used for products where strength, hardness, and flexibility are needed. The wood makes excellent fuel wood, as well.
The Oregon slender salamander is a species of salamander in the family Plethodontidae from the Northwestern United States.
The northern two-lined salamander is a species of salamander in the family Plethodontidae found in Canada and the United States. Its natural habitats are temperate forests, temperate shrubland, rivers, intermittent rivers, freshwater marshes, freshwater springs, arable land, and urban areas. It is more water-oriented than the related northern redback salamander, and can often be found in and around water such as rain puddles, streams, swamps, and damp stream beds, whereas the northern redback tends to be found in damp ground, but usually not near open water.
Pseudoeurycea lineola, commonly known as the Veracruz worm salamander or Mexican slender salamander, is a species of salamander in the family Plethodontidae. It is endemic to the eastern slope of the Trans-Mexican Volcanic Belt near Cuautlapan, in the west-central Veracruz, Mexico, at elevations of 800–1,250 m (2,620–4,100 ft) above sea level. Molecular evidence suggests that it consists of two distinct species. It was the type species of genus Lineatriton.
The natural history of Georgia covers many plant and animal species. The humid subtropical climate of Georgia influences its plant and animal life.
Ecotourism in the United States is commonly practiced in protected areas such as national parks and nature reserves. The principles and behaviors of ecotourism are slowly becoming more widespread in the United States; for example, hotels in some regions strive to be more sustainable.
The natural environment of Virginia encompasses the physical geography and biology of the U.S. state of Virginia. Virginia has a total area of 42,774.2 square miles (110,784.67 km2), including 3,180.13 square miles (8,236.5 km2) of water, making it the 35th-largest state by area. Forests cover 65% of the state, wetlands and water cover 6% of the land in the state, while 5% of the state is a mixture of commercial, residential, and transitional.
There are 14 species of amphibians and 5 species of reptiles known to occur in Mount Rainier National Park.
The North American Southeastern Plains are a Level III ecoregion designated by the Environmental Protection Agency (EPA) in ten U.S. states. The region takes a U shape starting in western Tennessee, going south through eastern Mississippi, and forming most of Alabama. On the eastern side, the plains lie between the Appalachian Mountains and the coastal plains, forming central Georgia, South Carolina, and North Carolina. It forms part of eastern Virginia before terminating in Maryland.
