Buttington Oak
The Buttington Oak was a tree near to Offa's Dyke at Buttington, Wales, said to have been planted to mark the site of the Battle of Buttington between the Vikings and a Mercian, Wessex and Welsh force in 893. It had been cyclically pollarded for timber until around 150 years ago. The oak tree was rediscovered in 2009. In 2017 it was badly damaged by storms, finally collapsing in February 2018. The Buttington Yew, also planted in commemoration of the battle in 893, survives and in 2022 was added to the roster of 70 Ancient Trees in The Queen's Green Canopy. History The oak was said to have been planted by locals to mark the 893 Battle of Buttington, a victory of an allied Mercian, Wessex and Welsh force against invading Vikings or as a boundary marker on Offa's Dyke. The tree was located near Welshpool and close to the dyke, an 8th-century earthwork that marked the border between Mercia and the Kingdom of Powys. The tree stood in fields on a flood plain to the north of Buttingt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quercus Robur
''Quercus robur'', commonly known as common oak, pedunculate oak, European oak or English oak, is a species of flowering plant in the beech and oak family, Fagaceae. It is a large tree, native plant, native to most of Europe west of the Caucasus. It is widely cultivated in temperate regions elsewhere and has escaped into the wild in scattered parts of China and North America.

The Brureika (Bridal Oak) in Norway with a circumference of (2018) and the Kaive Oak in Latvia with a circumference of are among the thickest trees in Northern Europe. The largest historical oak was known as the Imperial Oak from Bosnia and Herzegovina. This specimen was recorded at 17.5 m in circumference at breast height and estimated at over 150 m³ in total volume. It collapsed in 1998. The species has l ...

Individual Trees In Wales
An individual is that which exists as a distinct entity. Individuality (or self-hood) is the state or quality of being an individual; particularly (in the case of humans) of being a person unique from other people and possessing one's own needs or goals, rights and responsibilities. The concept of an individual features in diverse fields, including biology, law, and philosophy. Etymology From the 15th century and earlier (and also today within the fields of statistics and metaphysics) ''individual'' meant " indivisible", typically describing any numerically singular thing, but sometimes meaning "a person". From the 17th century on, ''individual'' has indicated separateness, as in individualism. Law Although individuality and individualism are commonly considered to mature with age/time and experience/wealth, a sane adult human being is usually considered by the state as an "individual person" in law, even if the person denies individual culpability ("I followed instr ...

Fungus
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chestnut Blight
The pathogenic fungus ''Cryphonectria parasitica'' (formerly ''Endothia parasitica'') is a member of the Ascomycota (sac fungi). This necrotrophic fungus is native to East Asia and South East Asia and was introduced into Europe and North America in the early 1900s. The fungus spread rapidly and caused significant tree loss in both regions. Overview ''Cryphonectria parasitica'' is a parasitic fungus of chestnut trees. This disease came to be known as chestnut blight. Naturally found in South East Asia, accidental introductions led to invasive populations of ''C. parasitica'' in North America and Europe. The fungal disease has had a devastating economic and social impact on communities in the eastern United States. In the first half of the 20th century it killed an estimated four billion trees; or, by another count, 3.5 billion trees through 2013. Less severe impacts have occurred in Europe due to widespread CHV1-induced ''hypovirulence''. CHV1 is one of at least two viral pathoge ...

Westerdijk Institute
The ''Westerdijk Institute'', or Westerdijk Fungal Biodiversity Institute, is part of the Royal Netherlands Academy of Arts and Sciences. The institute was renamed on 10 February 2017, after Johanna Westerdijk, the first female professor in the Netherlands and director of the institute from 1907 to 1958. The former name of the institute was CBS-KNAW Fungal Biodiversity Centre or Centraalbureau voor Schimmelcultures (''Central Bureau of Fungal Cultures'' in English). Despite the name change the collection maintained by the institute remains the CBS collections and the use of CBS numbers for the strains continues. The institute is located in Utrecht Science Park, a suburb of Utrecht. Before it had been located between offices at the university in Delft and in Baarn. CBS was established in 1904 as a collection of living fungi and algae at the Eleventh International Botanical Congress in Vienna. Since 2002 Pedro Willem Crous has been director of CBS as the successor of Dirk van der ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
