Ancient and veteran trees

We are currently surveying and identifying ancient and veteran trees in Buckinghamshire and Milton Keynes so that we can better protect them.

Types of tree

Veteran tree: A tree of biological, aesthetic, or cultural interest because of its size, age and condition; containing some ancient characteristics.

Ancient tree: A tree which has passed beyond maturity and is old in comparison to other trees within the same species.

Some people use the chronological ages of the trees to define an ancient tree, as an ancient tree is a tree that has reached a great age in comparison with others of the same species.

For example, a Birch tree can be considered ancient at the age of 150 years, whereas an Oak tree is not considered ancient until it is at least 400 years old.

The age of the tree can be difficult to estimate, therefore considering the ancient characteristics of the tree can also be a useful method to determine whether a tree is ancient or veteran.

Identifying an ancient or veteran tree

Veteran trees are in their mature stages of life, generally being older trees. All ancient trees will be veteran but not all veteran trees can be ancient. There is potential overlapping of classification for an individual tree.

Both veteran and ancient trees can show ancient characteristics, such as:

  • water holes or pockets
  • hollowing
  • large girth in comparison with its species
  • epicormics growth
  • tears or scars
  • evidence of decay and rot
  • cavities
  • the crown has retrenched through age
  • wide trunk
  • an "old" aesthetic appeal
  • dead wood

The more characteristics the tree has, the more likely it is to be ancient.

The Ancient Tree Forum have produced a guide to help people recognise trees that have special interest and to help justify why a tree (or group of trees) stands out from others of the same species.

Importance of ancient and veteran trees

In many parts of the world, ancient and veteran trees have become very rare. There are some still left in the UK, but they are struggling to survive with the present threats.

To conserve and protect these special trees of interest, we need to record them to ensure the continuity of the ancient tree populations and for people to understand their value.

Tell us about an ancient or veteran tree

If you know of any trees of special interest with ancient characteristics within Buckinghamshire and you would like to be included in our records, contact us.

Send us your name, contact details and the date you saw the tree. In addition we need a location (preferably a 6 figure grid reference).

The following information is also helpful:

  • owner of the land
  • is the tree accessible to the public (Yes or no)
  • species
  • characteristics of the tree
  • habitat (for example: garden, fields)
  • management (for example: low or high intensity, pruning)
  • photographs of the tree

You can also download and use the Trees of Interest Recording Form (DOCX, 32KB) and email this to us at erc@buckinghamshire.gov.uk.

To request this Recording Form in a different format, or if you would like more information about this project, please contact us.
