The exceptional trees at Bristol Zoo Gardens represent a unique historic collection that is nationally, and indeed internationally, important. There are dozens of individual trees in the Gardens that are noteworthy for their rarity, or as fine examples of their species. Several national 'Champion' trees have been recorded, and the collection as a whole is of immense value to the city for cultural, historic, and environmental reasons.
