Front Cover: Grand fir Abies grandis, at 63 m the tallest tree in Britain. Immediately fronted by specimens ofAbies alba (44 m) and Thuja plicata (40 m). Strone House, Strathclyde. (A. F. Mitchell) Champion Trees in the British Isles A. F. Mitchell1, V. E. Hallett and J. E. J. White2
Measurements Dimensions are metric; the height in metres, the diameter in centimetres. Diameter is derived from the measurement of girth, as this is the single parameter which sums the infinite number of diameters in an irregular cross-section. One inch of girth is 0.8085 cm diameter and one foot is 9.7 cm diameter. Those who visualise in imperial measure of girth can convert cm/diam. into ft and ins/girth very simply. The figures change little: 36 cm diam. = 3 ft 8 in girth; 44 cm diam. = 4 ft 6 in girth; 73 cm diam. = 7 ft 6 in girth; and 92 cm diam. = 9 ft 6 in. That is, turn the two figures into feet plus inches and add two (inches) when below 50 cm, add 3 in from 50 to 80 and 4 from 80 to 100. Above 100 add 5 (124 cm diam. = 12 ft 9 in girth); above 200 add 8.
Entries Listing is alphabetical by genus and species; space does not permit the inclusion of common names. Where a species is represented in the list by only one specimen, this is both the tallest and the stoutest. The majority of species are represented by two trees. The first is the tallest and the second is the stoutest. This second tree may not be very tall; it is NOT the second tallest. (Every preceding list published has given rise to claims that trees taller than the second entry should have been cited instead, thereby misunderstanding the basis of the list, despite it being clearly stated.) Several species have three, and a few, four entries. In these cases, in the height rating, there is more than one specimen of the top height quoted. In diameter rating it is where much the biggest cannot be measured at the standard 1.5 m (5 ft) and the biggest that can be so measured is added for comparison, and because it is usually a finer specimen. Heights have been rounded down to the nearest whole metre. 2
Scope o f the list Species have been included down to a considerable degree of rarity and only the very rarest, which have too few known specimens to compete effectively as tallest and stoutest are excluded; but where one specimen is clearly of outstanding size it is included even where very few are known. The more important cultivars are included. The total numbers listed are 548 species (188 conifers and 360 broadleaves) with 169 cultivars and varieties. The total number of entries is 1169.
The 1987 storm in south-east England After two successful previous editions (R&D Paper 138; 1985 and 1987) the gale of October 1987 made this revision a necessity. A disproportionate number of champions of rare species, particularly of broadleaves, were in the Sussex and Kent gardens that suffered the worst losses. So far it has been checked that 80 champions were blown down or terminally damaged but some 40 more yet to be seen were in the same region. They have, therefore, also been replaced in this list by the next biggest from the unaffected regions.
The third edition Normal factors of death, growth and discovery of new champions has had a great effect on numbers, if not quality, and 435 changes result from these. The opportunity has been taken to give more precedence to diameters measurable at the standard 1.5 m and less to those at 1 m or below, and to omit many more entries relating to pre-1980 as well as to include for the first time 52 species and 34 cultivars. There are thus some 606 new specimens and 139 updated figures. 3
*■ Alan Mitchell, an internationally acclaimed dendrologist, retired from Forestry Commission service on 31st December 1984 after a distinguished career of 32 years at the Forest Research Station, Alice Holt Lodge. He continues to be active as a consultant and, together with Victoria Hallett, is maintaining his records of tree measurements. In 1989 their register of 84 000 specimens of 1670 species and varieties was made a Registered Charity. Inquiries should be addressed to The Tree Register of the British Isles, 'Capers’, Portland Road, Burgess Hill, Sussex, RH15 9RL. 2 John White is the Forestry Commission’s Dendrologist based at Westonbirt Arboretum, Tetbury, Gloucestershire, GL8 8QS.
