In this, the second episode in our series, eucalypts: friend and foe, Chloe talks to world renowned tree authority Prof Greg Moore. In addition to his general interest in horticultural plant science, revegetation and ecology, Greg has a specific interest in all aspects of arboriculture, which is the scientific study of the cultivation and management of trees. He is an advisory board member of TreeNet and Greening Australia and is a former Principal of Melbourne University's Burnley campus. Greg’s insights into living with and managing trees in our cities, gardens and public spaces help enliven the discussion of the appropriate use for eucalypts for amenity and beauty.
