The Tree Register, or more fully, the Tree Register of the British Isles (T.R.O.B.I.), is a registered charity collating and updating a database of notable trees throughout Britain and Ireland. It comprises a computer database which in 2022 contained details of 250,000 trees. It was established in 1988 by co-founders Vicky Hallett, who later became Vicky Schilling, and Alan Mitchell, the internationally acclaimed dendrologist. The register contains computerised data from the original hand-written records of the two founders together with other 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 Loudon (1830s), Elwes and Henry (early 1900s) and the Hon. Maynard Greville (1950s), providing a valuable record of growth rates. The Tree Register was one of the founders of the Ancient Tree Hunt campaign. More information...
