Charles Sprague Sargent
Charles Sprague Sargent (April 24, 1841March 22, 1927) was an American botanist. He was appointed in 1872 as the first director of Harvard University's Arnold Arboretum in Boston, Massachusetts, and held the post until his death. He published several works of botany. Early life Sargent was the second son of Henrietta (Gray) and Ignatius Sargent, a Boston merchant and banker who grew wealthy on railroad investments. He grew up on his father's 130-acre (53-ha) estate in Brookline, Massachusetts. He attended Harvard College, where he graduated in Biology in the class of 1862. Sargent enlisted in the Union Army later that year, saw service in Louisiana during the American Civil War, and was mustered out in 1865. He traveled in Europe and Asia for three years. Career Having returned to his family's Brookline estate, "Holmlea", Sargent took over its management as a horticulturist, influenced by his cousin Henry Winthrop Sargent and H. H. Hunnewell of Wellesley, Massachusetts, Welle ... [...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 very rare in some of the higher elevations in northeastern Alabama. It is considered rare in Indiana. The Haudenosaunee maintain the tree as the central symbol of their multinational confederation, calling it the " Tree of Peace", where the Seneca use the name ''o’sóä’'' and the Kanienʼkehá:ka call it ''onerahtase'ko:wa''. Within the Wabanaki Confederacy, the Mi'kmaq use the term ''guow'' to name the tree, both the Wolastoqewiyik and Peskotomuhkatiyik call it ''kuw'' or ''kuwes'', and the Abenaki use the term ''kowa''. It is known as the "Weymouth pine" in the United Kingdom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dolly Sods Wilderness
The Dolly Sods Wilderness (DSW, originally simply Dolly Sods) is a U.S. Wilderness Area in the Allegheny Mountains of eastern West Virginia and is part of the Monongahela National Forest of the U.S. Forest Service. Dolly Sods is a rocky, high-altitude plateau with sweeping vistas and lifeforms normally found much farther north in Canada. To the north, the distinctive landscape of "the Sods" is characterized by stunted ("flagged") trees, wind-carved boulders, heath barrens, grassy meadows created in the last century by logging and fires, and sphagnum bogs that are much older. To the south, a dense cove forest occupies the branched canyon incised by the North Fork of Red Creek. The name derives from an 18th-century German homesteading family, the Dahles, and a local term for an open mountaintop meadow, a " sods". Geography Topography Dolly Sods is the highest plateau east of the Mississippi River with altitudes ranging from at the outlet of Red Creek to at the top of the ...

Roaring Plains West Wilderness
The Roaring Plains West Wilderness is a U.S. Wilderness Area in the Allegheny Mountains of eastern West Virginia, USA. It is part of the Monongahela National Forest and includes Mount Porte Crayon, the sixth highest point in the state. Known as "Roaring Plains West" to the advocates of a much larger area (15,138 acres) of proposed wilderness preservation, the RPW consists of set aside by the Wild Monongahela Act, which was made law on 30 March 2009. (There are also areas known as "Roaring Plains North" and "Roaring Plains East" not included in the WMA.) Along with neighboring Flatrock Plains, these areas comprise the highest plateau in the eastern United States. Geography The Roaring Plains and Flatrock Plains areas include portions of Randolph and Pendleton Counties. These high-elevation plateaux, which encompass the highest sphagnum bogs in West Virginia, consist of vast expanses of rocky, tree-studded plains surrounded by rock outcrops and cliffs offering impressive vi ...

Canaan Valley
Canaan Valley () is a large bathtub-shaped upland valley in northeastern Tucker County, West Virginia, USA. Within it are extensive wetlands and the headwaters of the Blackwater River which spills out of the valley at Blackwater Falls. It is a well-known and partially undeveloped scenic attraction and tourist draw. Since 1994, almost 70% of the Valley has become the Canaan Valley National Wildlife Refuge, the nation's 500th National Wildlife Refuge, with Canaan Valley Resort State Park and Blackwater Falls State Park nearby. Canaan Valley was designated a National Natural Landmark in 1974. The National Park Service citation indicates that the Valley is "a splendid 'museum' of Pleistocene habitats ... contain ng... an aggregation of these habitats seldom found in the eastern United States. It is unique as a northern boreal relict community at this latitude by virtue of its size, elevation and diversity." The local pronunciation of "Canaan" is , rather than the conventional ...

Acid Rain
Acid rain is rain or any other form of Precipitation (meteorology), precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH). Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and ranges from 4–5 on average. The more acidic the acid rain is, the lower its pH is. Acid rain can have harmful effects on plants, aquatic animals, and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the Properties of water, water molecules in the atmosphere to produce acids. Acid rain has been shown to have adverse impacts on forests, Fresh water, freshwaters, soils, microbes, insects and aquatic life-forms. In ecosystems, persistent acid rain reduces tree bark durability, leaving flora more susceptible to environmental stressors such as drought, heat/cold and pest infestation. Acid rain is also capable of detriment ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windthrow
In forestry, windthrow refers to trees uprooted by wind. Breakage of the tree bole (botany), bole (trunk) instead of uprooting is called windsnap. Blowdown refers to both windthrow and windsnap. Causes Windthrow is common in all forested parts of the world that experience storms or high wind speeds. The risk of windthrow to a tree is related to the tree's size (height and diameter), the 'sail area' presented by its crown, the anchorage provided by its roots, its exposure to the wind, and the local wind climate. A common way of quantifying the risk of windthrow to a forest area is to model the probability or 'return time' of a wind speed that would damage those trees at that location. Another potential method is the detection of scattered windthrow based on satellite images. Tree senescence can also be a factor, where multiple factors contributing to the declining health of a tree reduce its anchorage and therefore increase its susceptibility to windthrow. The resulting dama ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loam
Loam (in geology and soil science) is soil composed mostly of sand (particle size > ), silt (particle size > ), and a smaller amount of clay (particle size < ). By weight, its mineral composition is about 40–40–20% concentration of sand–silt–clay, respectively. These proportions can vary to a degree, however, and result in different types of loam soils: sandy loam, silty loam, clay loam, sandy clay loam, silty clay loam, and loam. In the USDA, United States Department of Agriculture, soil texture, textural classification triangle, the only soil that is not predominantly sand, silt, or clay is called "loam". Loam soils generally contain more nutrients, moisture, and humus than sandy soils, have better drainage and infiltration of water and air than silt- and clay-rich soils, and are easier to tillage, till than clay soils. In fact, the primary definition of loam in most dictionaries is soils containing hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. The general definition used is one followed by the United States Geological Survey and the Geological Survey of Canada to describe the respective countries' Physiographic region, physiographic regions. The U.S. uses the term Appalachian Highlands and Canada uses the term Appalachian Uplands; the Appalachian Mountains are not synonymous with the Appalachian Plateau, which is one of the provinces of the Appalachian Highlands. The Appalachian range runs from the Newfoundland (island), Island of Newfoundland in Canada, southwestward to Central Alabama in the United States; south of Newfoundland, it crosses the 96-square-mile (248.6 km2) archipelago of Saint Pierre and Miquelon, an overseas collectivity of France, meaning it is technica ...
