Alton Garden Tree Survey

Over 600 specimens in the garden

Tree Survey

The tree survey at Alton was undertaken by John Beetham in February, March and July 1998. The survey was undertaken to provide an overview of the horticultural diversity of the trees at Alton. Criteria for inclusion were major trees or trees that in some other way appear to relate to the significance of the property. The principal exclusions were rhododendrons, most hollies (except variegated or larger significant specimens which appear to have been intentionally planted), small trees and large shrubs from the "forested areas", other than some plants of particular horticultural significance or where they formed an important aesthetic or horticultural feature.

The main objectives of the survey were:

  • plant identification
  • estimate of age
  • preliminary assessment of condition
  • preliminary management recommendation.

Trees included or recommended for inclusion on the National Trust's Register of Significant Trees are indicated with the code NTRST. Trees are selected for listing based on their condition, size, and rarity. There are over 600 specimens identified and the names are listed below. There is of course more than one specimen of many of the trees in the garden. Click on the names that are bold green to open an image of the tree in a new window.
