Allegheny National Forest
The Allegheny National Forest is a National Forest in Northwestern Pennsylvania, about 100 miles northeast of Pittsburgh. The forest covers of land. Within the forest is Kinzua Dam, which impounds the Allegheny River to form Allegheny Reservoir. The administrative headquarters for the Allegheny National Forest is in Warren. The Allegheny National Forest has two ranger stations, one in Marienville, Forest County, and the other in Bradford, McKean County. The Allegheny National Forest lies in the heart of Pennsylvania's oil and gas region. It is only from the site of the first commercial oil well in the United States at Titusville, Pennsylvania. In 1981, about 17 percent of the state's crude oil production came from mineral rights owned by private individuals within the Forest boundary. History before 1923 Today the Allegheny Plateau is known for black cherry, maple and other hardwoods, but two hundred years ago these species were less numerous. Today's forest is largel ...

Maple
''Acer'' is a genus of trees and shrubs commonly known as maples. The genus is placed in the soapberry family Sapindaceae.Stevens, P. F. (2001 onwards). Angiosperm Phylogeny Website. Version 9, June 2008 nd more or less continuously updated since http://www.mobot.org/MOBOT/research/APweb/. There are approximately 132 species, most of which are native to Asia, with a number also appearing in Europe, northern Africa, and North America. Only one species, '' Acer laurinum'', extends to the Southern Hemisphere.Gibbs, D. & Chen, Y.

Settler
A settler or a colonist is a person who establishes or joins a permanent presence that is separate to existing communities. The entity that a settler establishes is a Human settlement, settlement. A settler is called a pioneer if they are among the first settling at a place that is new to the settler community. The process of settling land can be, and has often been, controversial: while human migration is a normal phenomenon by itself, it has not been uncommon throughout human history for settlers to have arrived in already-inhabited lands Settler colonialism, without the intention of living alongside the native population. In these cases, the conflict that arises between the settlers and the natives (or Indigenous peoples) may result in the dispossession of the latter within the contested territory, usually violently. While settlers can act independently, they may receive support from the government of their country or colonial empire or from a non-governmental organization as ...

Europe
Europe is a continent located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south, and Asia to the east. Europe shares the landmass of Eurasia with Asia, and of Afro-Eurasia with both Africa and Asia. Europe is commonly considered to be Boundaries between the continents#Asia and Europe, separated from Asia by the Drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea, and the waterway of the Bosporus, Bosporus Strait. "Europe" (pp. 68–69); "Asia" (pp. 90–91): "A commonly accepted division between Asia and Europe ... is formed by the Ural Mountains, Ural River, Caspian Sea, Caucasus Mountains, and the Black Sea with its outlets, the Bosporus and Dardanelles."

Native Americans In The United States
Native Americans (also called American Indians, First Americans, or Indigenous Americans) are the Indigenous peoples of the Americas, Indigenous peoples of the United States, particularly of the Contiguous United States, lower 48 states and Alaska. They may also include any Americans whose origins lie in any of the indigenous peoples of North or South America. The United States Census Bureau publishes data about "American Indians and Alaska Natives", whom it defines as anyone "having origins in any of the original peoples of North and South America ... and who maintains tribal affiliation or community attachment". The census does not, however, enumerate "Native Americans" as such, noting that the latter term can encompass a broader set of groups, e.g. Native Hawaiians, which it tabulates separately. The European colonization of the Americas from 1492 resulted in a Population history of Indigenous peoples of the Americas, precipitous decline in the size of the Native American ...

Tornado
A tornado is a violently rotating column of air that is in contact with the surface of Earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. It is often referred to as a twister, whirlwind or cyclone, although the word cyclone is used in meteorology to name a weather system with a low-pressure area in the center around which, from an observer looking down toward the surface of the Earth, winds blow counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. Tornadoes come in many shapes and sizes, and they are often (but not always) visible in the form of a funnel cloud, condensation funnel originating from the base of a cumulonimbus cloud, with a cloud of rotating debris and dust beneath it. Most tornadoes have wind speeds less than , are about across, and travel several kilometers (a few miles) before dissipating. The Tornado records#Highest winds observed in a tornado, most extreme tornadoes can attain wind speeds of mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deer
A deer (: deer) or true deer is a hoofed ruminant ungulate of the family Cervidae (informally the deer family). Cervidae is divided into subfamilies Cervinae (which includes, among others, muntjac, elk (wapiti), red deer, and fallow deer) and Capreolinae (which includes, among others reindeer (caribou), white-tailed deer, roe deer, and moose). Male deer of almost all species (except the water deer), as well as female reindeer, grow and shed new antlers each year. These antlers are bony extensions of the skull and are often used for combat between males. The musk deer ( Moschidae) of Asia and chevrotains ( Tragulidae) of tropical African and Asian forests are separate families that are also in the ruminant clade Ruminantia; they are not especially closely related to Cervidae. Deer appear in art from Paleolithic cave paintings onwards, and they have played a role in mythology, religion, and literature throughout history, as well as in heraldry, such as red deer that app ...

Eastern Cougar
The eastern cougar or eastern puma (''Puma concolor couguar'') is a subspecies designation proposed in 1946 for cougar populations in eastern North America. The subspecies as described in 1946 was declared extinct by the U.S. Fish and Wildlife Service in 2011. However, the 1946 taxonomy is now in question. The Canadian Wildlife Service has taken no position on the taxonomy. Cougars are currently common in western North America and may be expanding their range. Individuals are occasionally seen as vagrants in eastern North America. History of taxonomy In 1892, Robert Kerr of the Royal Physical Society and Royal Society of Surgeons assigned the name ''Felis couguar'' to eastern North America cougars north of Florida. Naturalist John James Audubon in 1851 believed that cougars in both North and South America were indistinguishable. The eastern cougar was first assigned to the subspecies ''Felis concolor couguar'' and the Florida panther to ''F. c. coryi''. Young and Goldman based ...

Eastern Wolf
The eastern wolf (''Canis lycaon'' or ''Canis lupus lycaon''), also known as the timber wolf, Algonquin wolf and eastern timber wolf, is a canine of debated taxonomy native to the Great Lakes region and southeastern Canada. It is considered either a unique subspecies of gray wolf, or red wolf, or a separate species from both. Many studies have found the eastern wolf to be the product of ancient and recent genetic admixture between the gray wolf and the coyote, while other studies have found some or all populations of the eastern wolf, as well as coyotes, originally separated from a common ancestor with the wolf over 1 million years ago and that these populations of the eastern wolf may be the same species as or a closely related species to the red wolf (''Canis lupus rufus'' or ''Canis rufus'') of the Southeastern United States. Regardless of its status, it is regarded as unique and therefore worthy of conservation with Canada citing the population in eastern Canada (also kn ...

Canopy (biology)
In biology, the canopy is the aboveground portion of a plant community, plant cropping or crop, formed by the collection of individual Crown (botany), plant crowns. In forest ecology, the canopy is the upper layer or habitat zone, formed by mature tree crowns and including other biological organisms (epiphytes, lianas, Arboreal, arboreal animals, etc.). The communities that inhabit the canopy layer are thought to be involved in maintaining forest diversity, Ecological resilience, resilience, and functioning. Shade trees normally have a dense canopy that blocks light from lower growing plants. Early observations of canopies were made from the ground using binoculars or by examining fallen material. Researchers would sometimes erroneously rely on extrapolation by using more reachable samples taken from the understory. In some cases, they would use unconventional methods such as chairs suspended on vines or hot-air dirigibles, among others. Modern technology, including adapted ...

Old-growth Forest
An old-growth forest or primary forest is a forest that has developed over a long period of time without disturbance. Due to this, old-growth forests exhibit unique ecological features. 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. One-third (34 percent) of the world's forests are primary forests. Old-growth features include diverse tree-related structures that provide diverse wildlife habitats 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 heights and diameters, and diverse tree species and classes and sizes of woody debris., the world has of primary forest ...

Black Cherry
''Prunus serotina'', commonly called black cherry,World Economic Plants: A Standard Reference, Second Edition'. CRC Press; 19 April 2016. . p. 833–. wild black cherry, rum cherry, or mountain black cherry, is a deciduous tree or shrub in the rose family Rosaceae. Despite its common names, it is not very closely related to commonly cultivated cherries. It is found in the Americas. Description ''Prunus serotina'' is a medium-sized, fast-growing forest tree growing to a height of . The leaves are long, ovate-lanceolate in shape, with finely toothed margins. Fall leaf color is yellow to red. Flowers are small, white and 5-petalled, in racemes long which contain several dozen flowers. The flowers give rise to reddish-black "berries" (drupes) fed on by birds, in diameter. For about its first decade the bark of a black cherry tree is thin, smooth, and banded, resembling a birch. A mature tree has very broken, dark gray to black bark. The leaves are long and shiny, resembling a so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
