Pollard trees
Pollarding is a form of tree management that removes the upper branches of a tree, resulting in a dense head of branches and/or foliage regrowth. Pollard trees take a characteristic shape as a result of this.
Historically this was common practice in wood pasture to provide leafy foliage as a diet supplement to grazing animals and also as a source of wood.
Many pollard trees you may come across in wood pasture are no longer being managed in this way, but they are still identifiable by their distinctive shape, with all the limbs growing from one height on the trunk, which often has a swollen knotty appearance.
Perhaps surprisingly, the periodic cutting involved in pollarding actually increases the longevity of the tree, causing many to survive as veteran and even ancient trees; providing fantastic deadwood in the bole of the tree and in all the nooks and crevices pollarding creates.
Many of these old trees may even be older than they look, the process of pollarding actually reduces the rate at which these trees grow, this means you can’t estimate their age so accurately using girth as you would with normal trees.

Veteran pollard with tear
At some point, this old pollard has lost one of it's branches, resulting in this tear down the trunk. As you can see from the scar tissue, the tree healed over the wound and the tree remains healthy. This can happen with 'lapsed' pollards (historically pollarded trees that have been allowed to grow out) as the wood connecting the trunk to the limb after pollarding is not as strong as it would be in a maiden tree. If the limbs are left to grow out, they can be too heavy for this weak point and eventually break. These oaks have not been pollarded for over 300 years so this is not an immediate concern.
