Mountain Skullcap
''Scutellaria montana'', with the common names largeflower skullcap, large-flowered skullcap and mountain skullcap, is an perennial forb first described by Alvan Chapman in 1878. This narrowly endemic species is found in the southeastern United States in parts of the Ridge and Valley and Cumberland Plateau Physiographic Provinces. Populations have been documented from four Tennessee counties and nine Georgia counties and is protected under the US Endangered Species act as it is a threatened species. The Latin specific epithet ''montana'' refers to mountains or coming from mountains. Description This plant has a single, erect square stem and may grow 30 to 60 cm in height. The leaves are simple, opposite in arrangement, lanceolate to ovate with crenate to serrate margins, and the blades are 5 to 8 cm long and 3 to 5 cm wide. Characteristic to this species, the leaves have a soft pubescence with glandular and non-glandular hairs on both surfaces. As the common ...

Quercus Montana
''Quercus montana'', the chestnut oak, is a species of oak in the white oak group, ''Quercus'' sect. ''Quercus''. It is native to the eastern United States, where it is one of the most important ridgetop trees from southern Maine southwest to central Mississippi, with an outlying northwestern population in southern Michigan. It is also sometimes called rock oak because of its presence in montane and other rocky habitats. Description As a consequence of its dry habitat and ridgetop exposure, the chestnut oak is not usually a large tree, typically growing to tall; specimens growing in better conditions can grow up to tall. They tend to have a similar spread of . A 10-year-old sapling grown in full sun will stand about tall. This species is often an important canopy species in an oak-heath forest. It is readily identified by its massively-ridged dark gray-brown bark, the thickest of any eastern North American oak. The leaves are long and broad, shallowly lobed with 10â ...

Flora Of Tennessee
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phyt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Threatened Flora Of The United States
Threatened species are any species (including animals, plants and fungi) which are vulnerable to endangerment in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of ''critical depensation'', a mathematical measure of biomass related to population growth rate. This quantitative metric is one method of evaluating the degree of endangerment. IUCN definition The International Union for Conservation of Nature (IUCN) is the foremost authority on threatened species, and treats threatened species not as a single category, but as a group of three categories, depending on the degree to which they are threatened: *Vulnerable species *Endangered species * Critically endangered species Less-than-threatened categories are near threatened, least concern, and the no longer assigned category of conservation dependent. Species which have not been evaluated (NE), or do not have sufficient data (data deficient) also are not considered "t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quarrying
A quarry is a type of open-pit mine in which dimension stone, rock, construction aggregate, riprap, sand, gravel, or slate is excavated from the ground. The operation of quarries is regulated in some jurisdictions to reduce their environmental impact. The word ''quarry'' can also include the underground quarrying for stone, such as Bath stone. Types of rock Types of rock extracted from quarries include: *Chalk *China clay *Cinder *Clay *Coal *Construction aggregate (sand and gravel) * Coquina *Diabase *Gabbro *Granite * Gritstone *Gypsum *Limestone *Marble *Ores *Phosphate rock *Quartz *Sandstone *Slate *Travertine Stone quarry Stone quarry is an outdated term for mining construction rocks (limestone, marble, granite, sandstone, etc.). There are open types (called quarries, or open-pit mines) and closed types ( mines and caves). For thousands of years, only hand tools had been used in quarries. In the 18th century, the use of drilling and blasting operations was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suburbs
A suburb (more broadly suburban area) is an area within a metropolitan area, which may include commercial and mixed-use, that is primarily a residential area. A suburb can exist either as part of a larger city/urban area or as a separate political entity. The name describes an area which is not as densely populated as an inner city, yet more densely populated than a rural area in the countryside. In many metropolitan areas, suburbs exist as separate residential communities within commuting distance of a city (cf "bedroom suburb".) Suburbs can have their own political or legal jurisdiction, especially in the United States, but this is not always the case, especially in the United Kingdom, where most suburbs are located within the administrative boundaries of cities. In most English-speaking countries, suburban areas are defined in contrast to central or inner city areas, but in Australian English and South African English, ''suburb'' has become largely synonymous with what i ...

Logging
Logging is the process of cutting, processing, and moving trees to a location for transport. It may include skidding, on-site processing, and loading of trees or logs onto trucks or skeleton cars. Logging is the beginning of a supply chain that provides raw material for many products societies worldwide use for housing, construction, energy, and consumer paper products. Logging systems are also used to manage forests, reduce the risk of wildfires, and restore ecosystem functions, though their efficiency for these purposes has been challenged. In forestry, the term logging is sometimes used narrowly to describe the logistics of moving wood from the stump to somewhere outside the forest, usually a sawmill or a lumber yard. In common usage, however, the term may cover a range of forestry or silviculture activities. Illegal logging refers to the harvesting, transportation, purchase, or sale of timber in violation of laws. The harvesting procedure itself may be illegal, includin ...

Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cornus Florida
''Cornus florida'', the flowering dogwood, is a species of flowering tree in the family Cornaceae native to eastern North America and northern Mexico. An endemic population once spanned from southernmost coastal Maine south to northern Florida and west to the Mississippi River. The tree is commonly planted as an ornamental in residential and public areas because of its showy bracts and interesting bark structure. Classification The flowering dogwood is usually included in the dogwood genus ''Cornus'' as ''Cornus florida'' L., although it is sometimes treated in a separate genus as ''Benthamidia florida'' (L.) Spach. Less common names for ''C. florida'' include American dogwood, Florida dogwood, Indian arrowwood, Cornelian tree, white cornel, white dogwood, false box, and false boxwood. Two subspecies are generally recognized: Description Flowering dogwood is a small deciduous tree growing to high, often wider than it is tall when mature, with a trunk diameter of up to . A ...

Chimaphila Maculata
''Chimaphila maculata'' (spotted wintergreen, also called striped wintergreen, striped prince's pine, spotted pipsissewa, ratsbane, or rheumatism root) is a small, perennial, evergreen herb native to eastern North America and Central America, from southern Quebec west to Illinois, and south to Florida and Panama. Description It has dark green, variegated leaves in length, and in width. The variegation of the leaves arises from the distinct white veins contrasted with the dark green of the leaf. The stems emerge from creeping rhizomes, growing tall. The nearly round flowers, which appear in late July to early August, are found on top of tall stalks. They are white or pinkish and are insect pollinated. The flowers mature to small ( in diameter) capsules bearing the seeds of the plant, which are dispersed by the wind. Ecology It can be found in sandy habitats, well-drained upland forests, oak-pine woods, and similar mesic habitats. It is very tolerant of acidic soil. Medicin ...

Hexastylis
''Hexastylis'' or heartleaf is a segregate of the genus '' Asarum'', in the family Aristolochiaceae. The group comprises ten species endemic to southeastern North America. It is a perennial, evergreen, herbaceous plant with leaves and flowers arising directly from the rhizomes. Hexastylis was once recognized at the level of genus, and in some floral treatments still is, yet it has been shown through morphological and molecular evidence that it is rooted within the genus '' Asarum''. Species There are eighteen species of ''Hexastylis'': * ''Hexastylis arifolia'' * ''Hexastylis callifolia'' * ''Hexastylis chueyi'' * ''Hexastylis contracta'' * ''Hexastylis finzelii'' * ''Hexastylis harperi'' * ''Hexastylis heterophylla'' * ''Hexastylis lewisii'' * ''Hexastylis minor'' * ''Hexastylis naniflora'' * ''Hexastylis rhombiformis'' * ''Hexastylis rollinsiae'' * ''Hexastylis rosei'' * ''Hexastylis ruthii ''Hexastylis'' or heartleaf is a segregate of the genus '' Asarum'', in the fam ...
