Quercus robur; English Oak

This Quercus was found along a pathway in Platt Fields and is a tall mature specimen.They can grow up to 36m tall. They prefer more heavier clay soils often found in woodlands especially in lowland areas as well as hilly areas. They are very old trees and live up to 700-800 years old. The branches often stick out at right angles and they often have dead branches on the top of the canopy.


 The leaves are deeply lobed and with two auricles at the base on very short stalks. The first set of leaves are normally eaten by insects and then the second load come through in about midsummer.


Male and female catkins are produced around the time the first set of leaves are coming in and the male ones die off after pollination by which time the leaves are fully open. Acorns then come through normally in groups of about 3.


The bark  is grey and gets thick and deeply fissured in mature trees.
