Species	Q. robur

Quercus robur, also known as the English oak, is a species of oak tree native to Europe, Western Asia, and North Africa. It is one of the most common and widespread tree species in Europe, and is often found in association with other tree species such as Fraxinus excelsior and Carpinus betulus. Quercus robur has been widely cultivated and introduced to other parts of the world, including North America, Australia, and New Zealand, where it is often found in urban forestry and landscape architecture projects, such as those designed by Frederick Law Olmsted and André Le Nôtre. The tree has also been the subject of study by numerous botanists, including Carl Linnaeus and John Ray.

Taxonomy

Quercus robur is a member of the Fagaceae family, which includes other tree species such as Fagus sylvatica and Castanea sativa. The species is closely related to other oak species, such as Quercus petraea and Quercus cerris, and is often hybridized with these species in horticulture and silviculture projects, such as those conducted by the Royal Horticultural Society and the Food and Agriculture Organization of the United Nations. The taxonomy of Quercus robur has been studied by numerous taxonomists, including Carolus Linnaeus and Joseph Dalton Hooker, who have worked at institutions such as the Royal Botanic Gardens, Kew and the New York Botanical Garden. Quercus robur has also been the subject of study by geneticists, such as Gregor Mendel and Barbara McClintock, who have worked at institutions such as the Max Planck Society and the National Institutes of Health.

Distribution_and_Habitat

Quercus robur is native to a wide range of habitats, including deciduous forests, woodlands, and grasslands, in Europe, Western Asia, and North Africa. The species is often found in association with other tree species, such as Quercus ilex and Pinus sylvestris, and is a common component of ecosystems such as the Atlantic mixed forests and the European temperate forests. Quercus robur has been introduced to other parts of the world, including North America, where it is often found in urban parks and gardens, such as those designed by Frederick Law Olmsted and Calvert Vaux, and in national parks, such as Yellowstone National Park and Yosemite National Park. The species has also been introduced to Australia and New Zealand, where it is often found in agroforestry and permaculture projects, such as those conducted by the Commonwealth Scientific and Industrial Research Organisation and the New Zealand Forest Research Institute.

Description

Quercus robur is a large deciduous tree that can grow up to 40 meters in height, with a broad crown and a straight trunk. The species has lobed leaves that are typically 7-14 cm long, with 3-5 lobes on each side of the midrib. The acorns of Quercus robur are an important food source for many wildlife species, including squirrels, birds, and insects, such as those found in the fauna of Europe and the fauna of North America. The tree has been the subject of study by numerous botanists, including John Lindley and George Bentham, who have worked at institutions such as the Royal Botanic Gardens, Kew and the British Museum of Natural History. Quercus robur has also been used in traditional medicine for centuries, with herbalists such as John Gerard and Nicholas Culpeper writing about its uses.
