| dbo:abstract | Alan F. Mitchell (4 November 1922 – 3 August 1995) was a British forester, dendrologist and botanist, and author of several books on trees. Born in Ilford, Essex, he almost single-handedly measured every notable tree in the British Isles, founding the Tree Register of the British Isles (T.R.O.B.I.), which held records of over 100,000 individual notable trees at the time of his death. During the Second World War, he served with the Fleet Air Arm in the East Asia. Returning by troop ship in the Red Sea at the end of the war, he pondered his future and decided it would be trees. In 1976, the Royal Forestry Society of England, Wales, and Northern Ireland awarded him its Medal for Distinguished Service to Forestry (Gold Medal) during a Society meeting at Westonbirt. (From a tribute by Esmond Harris, Quarterly Journal of Forestry, January 1996, page 67). His 1987 book The Guide to Trees of Canada and North America is dedicated to his sister Christine. The book makes occasional oblique reference to a trip to North America in 1976. Mitchell's Rule states: "If there are tree stumps or felled trunks nearby, count the annual growth rings and measure the trunk circumference to find local growth rates". (en) Alan F. Mitchell (4 de noviembre de 1922 – 3 de agosto de 1995) fue un dasónomo, dendrólogo, botánico inglés, y autor de varios libros sobre árboles. Casi sin ayuda, midió cada árbol notable en las islas Británicas, creando el Registro de Árboles de las islas Británicas (acrónimo en inglés T.R.O.B.I.), que mantenía un registro de más de 100.000 árboles notables individuales en el momento de su muerte. Durante la segunda guerra mundial, sirvió en el Arma Aérea, en el Lejano Oriente. Volviendo en un transporte de tropas en el mar Rojo al final de la guerra, meditaba su futuro y decidió que sería el estudio de árboles. Su libro de 1987 The Guide to Trees of Canada and North America lo dedicó a su hermana Christine. El libro hace referencia oblicua ocasional a un viaje a América del Norte en 1976. La regla de Mitchell argumenta: "Si hay tocones o troncos cerca, el conteo de los anilloss anuales y la medición de la circunferencia de troncos se encuentran las tasas locales de crecimiento".
