Sir Harold Hillier Gardens
The Sir Harold Hillier Gardens is an arboretum comprising 72 hectares (180 acres) accommodating over 42,000 trees and shrubs in about 12,000 taxa, notably a collection of oaks, camellia, magnolia and rhododendron. The Gardens are located northeast of the town of Romsey in Hampshire, England, and were formerly known simply as the Hillier Arboretum, founded by nurseryman Harold Hillier in June 1953 when he acquired Jermyn's House and its grounds. The arboretum was given to Hampshire County Council in 1977 to be managed as a charitable trust. Sir Harold Hillier was knighted in 1983, just two years before his death at age 80 in 1985. The Gardens were listed as Grade II on the National Register of Historic Parks and Gardens in 1997. Organisation Run as a registered charity, the Gardens are continually developed to further Sir Harold’s philosophy of horticulture, conservation, education and recreation. The president of the trust is the Duchess of Cornwall and the patrons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xanthogaleruca Luteola
''Xanthogaleruca luteola'', commonly known as the elm-leaf beetle, is a beetle species in the family Chrysomelidae that is native to Europe but invasive in other parts of the world.http://cisr.ucr.edu/elm_leaf_beetle.html - Center for Invasive Species Research Description The imago (adult beetle) is 6–8 mm in length, and ranges from yellow to green in colour, with a spot on its head, an hourglass mark and two spots on the pronotum, and a broad, dark stripe along the edge of each elytron. The larvae are usually black, occasionally black and yellow, with multiple rows of dots on the back and on the sides and < 13 mm long. The pupae are orange-yellow with black chaetae. The ova are yellow, and laid in spindle-like clusters of < 25 on the undersides of the elm leaves. Distribution These beetles are common in the Western Palearctic realm from Portugal to Central Asia.

Diameter At Breast Height
Diameter at breast height, or DBH, is a standard method of expressing the diameter of the trunk or bole of a standing tree. DBH is one of the most common dendrometric measurements. Tree trunks are measured at the height of an adult's breast, which is defined differently in different countries and situations. In many countries, DBH is measured at approximately above ground. Global variation and scientific precision The height can make a substantial difference to the measured diameter. In the United States, DBH is typically measured at above ground. In some countries, such as Australia, New Zealand, Burma, India, Malaysia, and South Africa, breast height diameter has historically been measured at a height of , but because of much active research into allometrics that are being applied to trees and forests, the convention of is more appropriate. Ornamental trees are usually measured at 1.5 metres above ground. Some authors have argued that the term DBH should be aboli ...

Ivy Hatch
Ightham ( ) is a village in Kent, England, located approximately four miles east of Sevenoaks and six miles north of Tonbridge. The parish includes the hamlet of Ivy Hatch. Ightham is famous for the nearby medieval manor of Ightham Mote (National Trust), although the village itself is of greater antiquity. Ightham is not mentioned in the ''Domesday Book'', but place-name evidence implies the name is derived from the Saxon 'Ehtaham'. 'Ehta' is a Jutish personal name, while 'ham' means settlement. The parish church dates from the 12th century, and in 1336 Edward II granted a request for permission to hold an annual fair in the village. Ightham was famous for growing Kentish cob nuts. These seem to have been cultivated first by James Usherwood, who lived at Cob Tree Cottage. There was a public house nearby called the Cob Tree Inn, which has now reverted to a private house. There are still a number of cob trees in and around the village, but the work of pruning them and picking ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tree Register Of The British Isles
The Tree Register, or more fully, the Tree Register of the British Isles (T.R.O.B.I.), is a registered charity collating and updating a database of notable trees throughout Britain and Ireland. It comprises a computer database which in 2022 contained details of 250,000 trees. It contains data from the original hand-written records of the late and internationally acclaimed dendrologist Alan Mitchell, and other historical records taken from reference works going back more than 200 years. . Recent height and girth measurements can be compared to those recorded by the likes of Loudon (1830s), Elwes and Henry (early 1900s) and the Hon. Maynard Greville (1950s), providing a valuable record of growth rates. The Tree Register was one of the founders of the Ancient Tree Hunt campaign. See also *The Tree Council The Tree Council was founded in 1974 in the United Kingdom, and became a Charitable organization#Charity registration, registered charity in 1978.

Fahrenheit
The Fahrenheit scale () is a temperature scale based on one proposed in 1724 by the physicist Daniel Gabriel Fahrenheit (1686–1736). It uses the degree Fahrenheit (symbol: °F) as the unit. Several accounts of how he originally defined his scale exist, but the original paper suggests the lower defining point, 0 °F, was established as the freezing temperature of a solution of brine made from a mixture of water, ice, and ammonium chloride (a salt). The other limit established was his best estimate of the average human body temperature, originally set at 90 °F, then 96 °F (about 2.6 °F less than the modern value due to a later redefinition of the scale). For much of the 20th century, the Fahrenheit scale was defined by two fixed points with a 180 °F separation: the temperature at which pure water freezes was defined as 32 °F and the boiling point of water was defined to be 212 °F, both at sea level and under standard atmospheric pressure. ...

Celsius
The degree Celsius is the unit of temperature on the Celsius scale (originally known as the centigrade scale outside Sweden), one of two temperature scales used in the International System of Units (SI), the other being the Kelvin scale. The degree Celsius (symbol: °C) can refer to a specific temperature on the Celsius scale or a unit to indicate a difference or range between two temperatures. It is named after the Swedish astronomer Anders Celsius (1701–1744), who developed a similar temperature scale in 1742. Before being renamed in 1948 to honour Anders Celsius, the unit was called ''centigrade'', from the Latin ''centum'', which means 100, and ''gradus'', which means steps. Most major countries use this scale; the other major scale, Fahrenheit, is still used in the United States, some island territories, and Liberia. The Kelvin scale is of use in the sciences, with representing absolute zero. Since 1743 the Celsius scale has been based on 0 °C for the freezing ...

Ohio
Ohio () is a state in the Midwestern region of the United States. Of the fifty U.S. states, it is the 34th-largest by area, and with a population of nearly 11.8 million, is the seventh-most populous and tenth-most densely populated. The state's capital and largest city is Columbus, with the Columbus metro area, Greater Cincinnati, and Greater Cleveland being the largest metropolitan areas. Ohio is bordered by Lake Erie to the north, Pennsylvania to the east, West Virginia to the southeast, Kentucky to the southwest, Indiana to the west, and Michigan to the northwest. Ohio is historically known as the "Buckeye State" after its Ohio buckeye trees, and Ohioans are also known as "Buckeyes". Its state flag is the only non-rectangular flag of all the U.S. states. Ohio takes its name from the Ohio River, which in turn originated from the Seneca word ''ohiːyo'', meaning "good river", "great river", or "large creek". The state arose from the lands west of the Appalachian Mountai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ohio State University
The Ohio State University, commonly called Ohio State or OSU, is a public land-grant research university in Columbus, Ohio. A member of the University System of Ohio, it has been ranked by major institutional rankings among the best public universities in the United States. Founded in 1870 as the state's land-grant university and the ninth university in Ohio with the Morrill Act of 1862, Ohio State was originally known as the Ohio Agricultural and Mechanical College and focused on various agricultural and mechanical disciplines, but it developed into a comprehensive university under the direction of then-Governor and later U.S. president Rutherford B. Hayes, and in 1878, the Ohio General Assembly passed a law changing the name to "the Ohio State University" and broadening the scope of the university. Admission standards tightened and became greatly more selective throughout the 2000s and 2010s. Ohio State's political science department and faculty have greatly contri ...

Cultivar
A cultivar is a type of cultivated plant that people have selected for desired traits and when propagated retain those traits. Methods used to propagate cultivars include: division, root and stem cuttings, offsets, grafting, tissue culture, or carefully controlled seed production. Most cultivars arise from purposeful human manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in ''Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants that share the unique characteristics that define the cultivar. was coined as a term meaning "cultivated variety ...

Fareham
Fareham ( ) is a market town at the north-west tip of Portsmouth Harbour, between the cities of Portsmouth and Southampton in south east Hampshire, England. It gives its name to the Borough of Fareham. It was historically an important manufacturer of bricks, used to build the Royal Albert Hall, and grower of strawberries and other seasonal fruits. Current employers include Fareham Shopping Centre, small-scale manufacturers, and the Defence Science and Technology Laboratory. History Archaeological excavations around the old High Street area and the church of St Peter & Paul on high ground over the Wallington Estuary have yielded evidence of settlement on the site contemporary with the Roman occupation. No extensive programme of investigation has been possible owing to the historic nature of the buildings in this area. The town has a documented history dating back to the Norman era, when a part of William's army marched up from Fareham Creek before continuing to the Saxon c ...
