Quercus robur (Pedunculate Oak) 

Other Names: Common Oak, European Oak, English Oak. 
 
Description: Often known as the ruling majesty of the woods this is a large deciduous tree commonly seen in woodlands, parks and hedgerows throughout the UK. With an often large trunk circumference of up to 4m in “Grand” Oaks, this is the thickest tree on average in the country. Very similar to the Sessile Oak but distinguished by having no stalk from twig to leaf and with a stalk from twig to acorn cup. Deeply fissured grey bark. 
 
Uses: Oak trees produce one of the hardest and most durable wood on the planet and as such have been greatly valued for millennia. However, they are very slow growing and can take 150 years to be most useful in construction. Modern uses are flooring, wine barrels, furniture and firewood, but famous historical uses are strong gates to castles and building wooden battleships, especially during the Napoleonic wars where one ship of the line could use as many as 400 trees. 
 
Conservation Value: Whether Sessile or Pedunculate, Oaks support more wildlife that any other native species making them invaluable in conservation terms. They are the sole provider of habitat for 257 species of insect which are in turn the food source for birds and other species of predator. The bark provides ideal locations for mosses, lichens and liverworts and the deadwood cavities often found in mature trees provide nesting and roosting opportunities for birds and bats. 
 
Preferred Locations: Chalk, clay, sand and loam soils which are moist but well drained and in full sun to partial shade.
