Bedgebury Pinetum
Bedgebury National Pinetum at Bedgebury, Kent, in the United Kingdom, is a recreational and conservational arboretum managed by Forestry England that was established as the National Conifer Collection in 1925 and is now recognised as the most complete collection of conifers on one site anywhere in the world. The collection has over 10,000 trees growing across , including rare, endangered and historically important specimens. Bedgebury National Pinetum conducts conservation work, is home to some 56 vulnerable or critically endangered species, and houses five National Plant Collections. History Bedgebury is first mentioned in an Anglo-Saxon charter in AD 841, the name deriving from the Old English '' bycgan'', meaning "buy", and the Kentish , meaning "to bend or turn", possibly in reference to a stream. John de Bedgebury is listed as the earliest resident of Bedgebury, in the time of Edward II. In the 15th century Agnes de Bedgebury, sister and heir of John (died 1424) mar ...

Conifer
Conifers are a group of conifer cone, cone-bearing Spermatophyte, seed plants, a subset of gymnosperms. Scientifically, they make up the phylum, division Pinophyta (), also known as Coniferophyta () or Coniferae. The division contains a single extant class (biology), class, Pinopsida. All Neontology, extant conifers are perennial plant, perennial woody plants with secondary growth. The great majority are trees, though a few are shrubs. Examples include Cedrus, cedars, Pseudotsuga, Douglas-firs, Cupressaceae, cypresses, firs, junipers, Agathis, kauri, larches, pines, Tsuga, hemlocks, Sequoioideae, redwoods, spruces, and Taxaceae, yews.Campbell, Reece, "Phylum Coniferophyta". Biology. 7th. 2005. Print. P. 595 As of 1998, the division Pinophyta was estimated to contain eight families, 68 genera, and 629 living species. Although the total number of species is relatively small, conifers are ecology, ecologically important. They are the dominant plants over large areas of land, most ...

William Beresford, 1st Viscount Beresford
General William Carr Beresford, 1st Viscount Beresford, 1st Marquis of Campo Maior, (; 2 October 1768 – 8 January 1854) was an Anglo-Irish soldier and politician. A general in the British Army and a Marshal in the Portuguese Army, he fought alongside The Duke of Wellington in the Peninsular War and held the office of Master-General of the Ordnance in 1828 in Wellington's first ministry. He led the 1806 failed British invasion of Buenos Aires. Background Beresford was the illegitimate son of the 1st Marquess of Waterford. He was the brother of Admiral Sir John Beresford, 1st Baronet (who was also illegitimate), and the half-brother of the 2nd Marquess of Waterford, Archbishop Lord John Beresford and General Lord George Beresford. Peninsular War Commander in Chief of the Portuguese Army In that same year Beresford was sent to Madeira, which he occupied in name of the Queen of Portugal, remaining there for six months as Governor and Commander in Chief. The exiled Portu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leyland Cypress
The Leyland cypress, ''Cupressus'' × ''leylandii'', often referred to simply as leylandii, is a fast-growing coniferous evergreen tree much used in horticulture, primarily for hedges and screens. Even on sites of relatively poor culture, plants have been known to grow to heights of in 16 years. Their rapid, thick growth means they are sometimes used to achieve privacy, but such use can result in disputes with neighbours whose own property becomes overshadowed. The tree is a hybrid of Monterey cypress ('' Cupressus macrocarpa'') and Nootka cypress ('' Cupressus nootkatensis''). It is almost always sterile, and is propagated mainly by cuttings. History In 1845, the Leighton Hall, Powys estate was purchased by the Liverpool banker Christopher Leyland. In 1847, he gave it to his nephew John Naylor (1813–1889). Naylor commissioned Edward Kemp to lay out the gardens, which included redwoods, monkey puzzle trees and two North American species of conifers in close proximity to ...

Abies Grandis
''Abies grandis'' (grand fir, giant fir, lowland white fir, great silver fir, western white fir, Vancouver fir, or Oregon fir) is a fir native to the Pacific Northwest and Northern California of North America, occurring at altitudes of sea level to . It is a major constituent of the Grand Fir/Douglas Fir Ecoregion of the Cascade Range. The tree typically grows to in height, and may be the tallest ''Abies'' species in the world. There are two varieties, the taller coast grand fir, found west of the Cascade Mountains, and the shorter interior grand fir, found east of the Cascades. It was first described in 1831 by David Douglas. It is closely related to white fir. The bark was historically believed to have medicinal properties, and it is popular in the United States as a Christmas tree. Its lumber is a softwood, and it is harvested as a hem fir. It is used in paper-making, as well as construction for framing and flooring, where it is desired for its resistance to splitting a ...

Gene Bank
Gene banks are a type of biorepository that preserves genetic material. For plants, this is done by in vitro storage, freezing cuttings from the plant, or stocking the seeds (e.g. in a seedbank). For animals, this is done by the freezing of sperm and eggs in zoological freezers until further need. With corals, fragments are taken and stored in water tanks under controlled conditions. Genetic material in a 'gene bank' is preserved in a variety of ways, such as freezing at -196° Celsius in liquid nitrogen, being placed in artificial ecosystems, and put in controlled nutrient mediums. Accession is the common term given to an individual sample in a gene bank, such as a distinct species or variety. In plants, it is possible to unfreeze the material and propagate it. However, in animals, a living female is required for artificial insemination. While it is often difficult to use frozen animal sperm and eggs, there are many examples of it being done successfully. In an effort to c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temperateness
In geography, the temperate climates of Earth occur in the middle latitudes (23.5° to 66.5° N/S of Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates, where such variations are often small and usually only have precipitation changes. In temperate climates, not only do latitudinal positions influence temperature changes, but sea currents, prevailing wind direction, continentality (how large a landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C, when the mean temperature is above but below in the coldest month to account for the persistency of frost. However, other climate classifications set the minimum at . Zones and climates The north temperate zone extends from the Tropic of Cancer (approximately 23.5° north latitude) to the Arctic ...

Air Pollution
Air pollution is the contamination of air due to the presence of substances in the atmosphere that are harmful to the health of humans and other living beings, or cause damage to the climate or to materials. There are many different types of air pollutants, such as gases (including ammonia, carbon monoxide, sulfur dioxide, nitrous oxides, methane, carbon dioxide and chlorofluorocarbons), particulates (both organic and inorganic), and biological molecules. Air pollution can cause diseases, allergies, and even death to humans; it can also cause harm to other living organisms such as animals and food crops, and may damage the natural environment (for example, climate change, ozone depletion or habitat degradation) or built environment (for example, acid rain). Air pollution can be caused by both human activities and natural phenomena. Air pollution is a significant risk factor for a number of pollution-related diseases, including respiratory infections, heart disease, COPD ...
