The late Alan Mitchell, an internationally acclaimed dendrologist, retired from Forestry Commission service on 31st December 1984 after a distinguished career at the Forest Research Station, Alice Holt Lodge in Surrey. With Victoria Schilling, he founded the Tree Register of the British Isles (TROBI) which is a Registered Charity.
Victoria Schilling has maintained the TROBI register of tree measurements since the foundation of the Charity and co-ordinates the work of an increasing number of volun teer dendrologists.
John White, who retired in 1997, was the Forestry Commission's Research dendrologist based at Westonbirt Arboretum, Tetbury, Gloucestershire, GL8 8QS, UK.

In order to keep this publication and the Tree Register up to date the authors depend upon, and are grateful for, advice from readers about the condition of existing trees and information about potential new champions.

Very occasionally, where trees = are leaning badly or even 'reclining', the actual f. forma length from the stump to the end of what was once the top most branch is measured and this nv. = nothovar action is recorded. Recent storms and remedial lopping have caused the heights of some trees to subsp. = subspecies be reduced in this edition. See Conversion Table 1. 'Name' = cultivar
Diam eter (Name) = commonly used synonym Diameter is actually derived from the measure ment of girth, as this is the single parameter which (*) = tree forked at the base or sums the infinite number of diameters in an otherwise deformed irregular stem cross-section. Traditionally measurements have been made on standing trees (atOOm) = diameter measurement at 1.5 m (5 ft) above the ground, and on the upper height side of any slope. A standard metric tape measuring girth can easily be converted to a + = more than one stem, diameter measurement by reading centimetres sometimes measured girth and dividing by 7t (3.14159). To convert girth (00 + 00 + 00) measurements in feet and inches to centimetres diameter, first change to inches and then multiply E = estimated by 0.8085. As a rough guide 1 ft of girth is equal to 9.7 cm (almost 10 cm) of diameter. See Conversion Table 2. = measurement not available Conversion Table 1.
