A unique record of Notable and Ancient Trees in Britain and Ireland

The Tree Register

What is the Tree Register?

  • The Tree Register is a registered charity collating and updating a database of notable trees throughout Britain and Ireland.
  • It provides information on the size and growth of trees which is not available from any other source.
  • This unique register comprises of a computer database with details of more than 150,000 trees.
  • It contains data from the original hand written records of the late and internationally acclaimed dendrologist Alan Mitchell.
  • It includes historical records taken from reference works going back more than 200 years. Recent height and girth measurements can be compared to those recorded by the likes of J.C. Louden (1830`s), Henry Elwes and Augustine Henry (early 1900`s) and the Hon. Maynard Greville (1950`s) providing a valuable record of growth rates.
  • It records details of rare, unusual and historically significant trees.
  • It provides full data on the largest trees of each species - the definitive record of Britain and Ireland's champion trees.
  • The Tree Register organises a volunteer network of over 50 tree measurers who update historical records and discover over 2,000 new trees worthy of inclusion each year.
  • The records held are unique in as much as they represent the only comprehensive source of information on the size and location of trees in Britain and Ireland.
  • The importance, appreciation and enjoyment of any tree can be greatly enhanced by knowing it is of particular significance as a rare or exceptional specimen locally or nationally.
  • Owners often have trees which are far more unusual than they realise; either rare in cultivation or of exceptional age, stature and vigour.
