Champion Trees of Britain and Ireland: The Tree Register Handbook (£25) is targeted at professionals and nature lovers. It contains an A-Z listing aimed to capture for the first time all species in cultivation in the Britain Isles, according to author Owen Johnson.
Co-produced by the Tree Register and published by Kew Publishing, it also includes a foreword by Prince Charles, personal insights, local knowledge and more than 5,000 photographs.
Churchyard yews dating back 5,000 years are among the oldest, a 64.3m grand fir the tallest and a Sessile oak one of the biggest, at 35m tall and 274cm thick.
Other sections include a gazetteer to visiting the specimens, a checklist and index of synonyms and common names. Johnson said three-fifths of the trees were newly discovered or re-recorded since the 2003 edition.
