Cataract Bog
A cataract bog is a rare ecological community formed where a permanent stream flows over a granite outcropping. The sheeting of water keeps the edges of the rock wet without eroding the soil; in this precarious location no tree or large shrub can maintain a roothold. The result is a narrow, permanently wet, sunny habitat. While a cataract bog is host to plants typical of a bog, it is technically a fen. Bogs get water from the atmosphere, while fens get their water from groundwater seepage. Cataract bogs inhabit a narrow, linear zone next to the stream and are partly shaded by trees and shrubs in the adjacent plant communities. Algae growing on the rocks can make the surface slippery and dangerous for those exploring a cataract bog. Typical species The rushing water carves out small depressions where soil accumulates, forming micro-islands that play host to plants that thrive with low levels of nutrients and shallow root structures. Typical species include Sphagnum moss; carnivo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Granite
Granite ( ) is a coarse-grained (phanerite, phaneritic) intrusive rock, intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dike (geology), dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF diagram, QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) conta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Oxypolis Rigidior
''Oxypolis rigidior'', known as cowbane, common water dropwort, stiff cowbane, pig-potato, and Cherokee swamp potato, is a species of flowering plant in the Apiaceae, carrot family native to eastern North America. It is a perennial wildflower found in wet habitats. ''Oxypolis rigidior'' has been reported as being poisonous to some mammals, but it is also considered edible and safe by some authors. Description ''Oxypolis rigidior'' is 2–6 foot tall perennial herb of eastern North America. Its leaves are compound, odd-pinnate with 7-11 leaflets, and have variable shape. Umbels of 3 mm white flowers appear August to October. Flat fruits with conspicuous "wings" appear October through November. The variable leaf shape may make identification challenging. Water hemlock, a related very poisonous species, which sometimes even shares the common name "cowbane", is similar, as is the closely related Savanna cowbane (''Oxypolis ternata'').

Bogs
A bog or bogland is a wetland that accumulates peat as a deposit of dead plant materials often mosses, typically sphagnum moss. It is one of the four main Wetland#Types, types of wetlands. Other names for bogs include mire, mosses, quagmire, and muskeg; alkaline mires are called fens. A bayhead is another type of bog found in the forest of the Gulf Coast states in the United States.Watson, Geraldine Ellis (2000) ''Big Thicket Plant Ecology: An Introduction'', Third Edition (Temple Big Thicket Series #5).

Retrieved 7 July 2020 They are often covered in Ericaceae, heath or heather shrubs rooted in the sphagnum moss and peat. The gradual accumulation of decayed plant material in a bog functions as a carbon sink. Bogs occur where the water at the ground surface is acidic and low in nutrients. A bog usually is ...

Appalachian Bogs
Appalachian bogs are boreal or hemiboreal ecosystems, which occur in many places in the Appalachian Mountains, particularly the Allegheny Mountains, Allegheny and Blue Ridge Mountains, Blue Ridge subranges. Though popularly called bogs, many of them are technically fens. Natural history After the Pleistocene ice ages, species and ecosystems that had shifted southward often survived in local refugium (population biology), refugia. As a result, cold-adapted ecosystems, such as bogs, remain as far south as East Tennessee and Western North Carolina. Development of land has greatly reduced both the number and acreage of the bogs in North Carolina. Bog ecosystems evolved in humid cold temperate regions and are generally ombrotrophic which means the system is dependent on precipitation for moisture and nutrient inputs. Shady Valley bogs Situated between Holston Mountain and the Iron Mountains, the community of Shady Valley, Tennessee, once contained an estimated 10,000 acres (40 ...

Blue Ridge Escarpment
The Blue Ridge Mountains are a physiographic province of the larger Appalachian Highlands range. The mountain range is located in the Eastern United States and extends 550 miles southwest from southern Pennsylvania through Maryland, West Virginia, Virginia, North Carolina, South Carolina, Tennessee, and Georgia. The province consists of northern and southern physiographic regions, which divide near the Roanoke River gap. To the west of the Blue Ridge, between it and the bulk of the Appalachians, lies the Great Appalachian Valley, bordered on the west by the Ridge and Valley province of the Appalachian range. The Blue Ridge Mountains are known for having a bluish color when seen from a distance. Trees put the "blue" in Blue Ridge, from the isoprene released into the atmosphere. This contributes to the characteristic haze on the mountains and their perceived color. Within the Blue Ridge province are two major national parks: Shenandoah National Park in the northern section and Gr ...

Appalachian Mountains
The Appalachian Mountains, often called the Appalachians, are a mountain range in eastern to northeastern North America. The term "Appalachian" refers to several different regions associated with the mountain range, and its surrounding terrain.

Castilleja Coccinea
''Castilleja coccinea'', commonly known as scarlet Indian paintbrush or scarlet painted-cup, is a biennial plant, biennial flowering plant in the Orobanchaceae (broomrape) family. It is usually found in prairies, rocky glades, moist and open woodlands, thickets, and along streams in central and eastern North America. Description It is an upright, hairy, tall hemiparasitic plant. In its first year, the plant appears as a basal rosette, and in the second year the stem, usually unbranched, rises from the rosette. The basal leaves are oblong and mostly entire, and usually die before the flowers appear. The alternate stem leaves are deeply and irregularly lobed and measure up to long. The common names for this plant reflect the showy red bracts, inside of which is the actual greenish-yellow corolla (botany), corolla ("flower"). ''Castilleja coccinea'' can be distinguished from other ''Castilleja'' of the southeastern US because it has a long, thin yellowish or orangish lip on the c ...
