Ancient Trees

Ancient trees are trees of great age – over 300 years for an oak tree.

Ancient oaks may be far fatter than usual with a very wide trunk  or a squat or dumpy in appearance. They are often gnarled or showing signs of decay such as having hollow insides.


To the untrained eye they may look in poor shape but in reality they are probably very healthy for such a great age.

Oaks are generally regarded as having more associated species of wildlife than any other native trees in England

Ancient oaks are particularly important as habitats for many of these organisms.


Not only do they provide 'services' for a very long time at the same place, but as they grow larger and age, they provide additional niches for yet other organisms to exploit.
