Anders Run Natural Area
Anders Run Natural Area is a protected area in Warren County, Pennsylvania. It is part of Cornplanter State Forest. It contains about of old-growth forest including the tree species Eastern White Pine, Eastern Hemlock, Cucumber Magnolia, American Beech, American Hornbeam, Black Cherry, and oaks. Although parts of the natural area were logged during the first two decades of the 19th century, tree rings of fallen trees have revealed 200-year-old white pines and 400-year-old hemlocks. In addition to being the oldest, these two tree species are also the largest, and some of the white pines are over in diameter at breast height. In addition to its forests, the Natural Area also has a stream with native trout and fine stands of wildflowers. There is a historic residence on the property built in 1841 called the "Little Stone House," though in recent years the structure has fallen into a severe state of disrepair. The Natural Area has about of hiking trails. See also *List of ol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protected Area
Protected areas or conservation areas are locations which receive protection because of their recognized natural, ecological or cultural values. There are several kinds of protected areas, which vary by level of protection depending on the enabling laws of each country or the regulations of the international organizations involved. Generally speaking though, protected areas are understood to be those in which human presence or at least the exploitation of natural resources (e.g. firewood, non-timber forest products, water, ...) is limited. The term "protected area" also includes marine protected areas, the boundaries of which will include some area of ocean, and transboundary protected areas that overlap multiple countries which remove the borders inside the area for conservation and economic purposes. There are over 161,000 protected areas in the world (as of October 2010) with more added daily, representing between 10 and 15 percent of the world's land surface area. As of 20 ...

Cornplanter State Forest
Cornplanter State Forest is a Pennsylvania State Forest in Pennsylvania Bureau of Forestry District #14. The main office is located in North Warren in Warren County, Pennsylvania, in the United States. It is named for Chief Cornplanter of the Seneca Nation, one of the tribes of the Iroquois Confederacy. The forest is found on in Crawford, Forest, and Warren Counties. The district also covers Erie and the northern part of Venango Counties. History Cornplanter State Forest was formed as a direct result of the depletion of the forests of Pennsylvania that took place during the mid-to-late 19th century. Conservationists like Dr. Joseph Rothrock became concerned that the forests would not regrow if they were not managed properly. Lumber and Iron companies had harvested the old-growth forests for various reasons. The clear cut the forests and left behind nothing but dried tree tops and rotting stumps. The sparks of passing steam locomotives ignited wildfires that prevented the fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Old-growth Forest
An old-growth forestalso termed primary forest, virgin forest, late seral forest, primeval forest, or first-growth forestis a forest that has attained great age without significant disturbance, and thereby exhibits unique ecological features, and might be classified as a climax community. 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. More than one-third (34 percent) of the world's forests are primary forests. Old-growth features include diverse tree-related structures that provide diverse wildlife habitat 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 height ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eastern White Pine
''Pinus strobus'', commonly called the eastern white pine, northern white pine, white pine, Weymouth pine (British), and soft pine is a large pine native to eastern North America. It occurs from Newfoundland, Canada west through the Great Lakes region to southeastern Manitoba and Minnesota, United States, and south along the Appalachian Mountains and upper Piedmont to northernmost Georgia and perhaps very rarely in some of the higher elevations in northeastern Alabama. It is considered rare in Indiana. The Native American Haudenosaunee named it the "Tree of Peace". It is known as the "Weymouth pine" in the United Kingdom, after Captain George Weymouth of the British Royal Navy, who brought its seeds to England from Maine in 1605. Distribution ''P. strobus'' is found in the nearctic temperate broadleaf and mixed forests biome of eastern North America. It prefers well-drained or sandy soils and humid climates, but can also grow in boggy areas and rocky highlands. In mixed f ...

Eastern Hemlock
''Tsuga canadensis'', also known as eastern hemlock, eastern hemlock-spruce, or Canadian hemlock, and in the French-speaking regions of Canada as ''pruche du Canada'', is a coniferous tree native to eastern North America. It is the state tree of Pennsylvania. Eastern hemlocks are widespread throughout much of the Great Lakes region, the Appalachian Mountains, the Northeastern United States, and Maritime Canada. They have been introduced in the United Kingdom and mainland Europe, where they are used as ornamental trees. Eastern hemlock populations in North America are threatened in much of their range by the spread of the invasive Hemlock woolly adelgid, which infests and eventually kills trees. Declines in population from hemlock wooly adelgid infestation have led to ''Tsuga canadensis'' being listed as Near Threatened on the IUCN Red List. Eastern hemlocks are long lived trees, with many examples living for more than 500 years. They can grow to heights of more than , and are tol ...

Cucumber Magnolia
''Magnolia acuminata'', commonly called the cucumber tree (often spelled as a single word "cucumbertree"), cucumber magnolia or blue magnolia, is one of the largest magnolias, and one of the cold-hardiest. It is a large forest tree of the Eastern United States and Southern Ontario in Canada. It is a tree that tends to occur singly as scattered specimens, rather than in groves.Sternberg, G., & Wilson, J. (2004). Native Trees for North American Landscapes. Portland, Oregon:Timber Press The cucumber tree is native primarily within the Appalachian belt, including the Allegheny Plateau and Cumberland Plateau, up to western Pennsylvania and New York. There are also numerous disconnected outlying populations through much of the southeastern U.S., and a few small populations in Southern Ontario. In Canada, the cucumber tree is listed as an endangered species and is protected under the Canadian Species at Risk Act.White, D.J. (2000). Update COSEWIC Status Report on the Cucumber Tree ''M ...

American Beech
''Fagus grandifolia'', the American beech or North American beech, is a species of beech tree native to the eastern United States and extreme southeast of Canada. Description ''Fagus grandifolia'' is a large deciduous tree growing to tall, with smooth, silver-gray Bark (botany), bark. The leaves are dark green, simple and sparsely-toothed with small teeth that terminate each vein, long (rarely ), with a short Petiole (botany), petiole. The winter twigs are distinctive among North American trees, being long and slender ( by ) with two rows of overlapping scales on the buds. Beech buds are distinctly thin and long, resembling cigars; this characteristic makes beech trees relatively easy to identify. The tree is monoecious, with flowers of both sexes on the same tree. The fruit is a small, sharply-angled nut (fruit), nut, borne in pairs in a soft-spined, four-lobed husk. It has two means of reproduction: one is through the usual dispersal of seedlings, and the other is through r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Hornbeam
''Carpinus caroliniana'', the American hornbeam, is a small hardwood tree in the genus ''Carpinus''. American hornbeam is also known as blue-beech, ironwood, musclewood and muscle beech. It is native to eastern North America, from Minnesota and southern Ontario east to Maine, and south to eastern Texas and northern Florida. It also grows in Canada (southwest Quebec and southeast Ontario). It occurs naturally in shaded areas with moist soil, particularly near the banks of streams or rivers, and is often a natural constituent understory species of the riverine and maritime forests of eastern temperate North America. Description American hornbeam is a small tree reaching heights of , rarely , and often has a fluted and crooked trunk. The bark is smooth and greenish-grey, becoming shallowly fissured in all old trees.

Tree Ring
Dendrochronology (or tree-ring dating) is the scientific method of dating tree rings (also called growth rings) to the exact year they were formed. As well as dating them, this can give data for dendroclimatology, the study of climate and atmospheric conditions during different periods in history from wood. Dendrochronology derives from Ancient Greek (), meaning "tree", (), meaning "time", and (), "the study of". Dendrochronology is useful for determining the precise age of samples, especially those that are too recent for radiocarbon dating, which always produces a range rather than an exact date. However, for a precise date of the death of the tree a full sample to the edge is needed, which most trimmed timber will not provide. It also gives data on the timing of events and rates of change in the environment (most prominently climate) and also in wood found in archaeology or works of art and architecture, such as old panel paintings. It is also used as a check in radiocarb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
