Tipping, who has been central in setting risk-limitation tree policies, has been asked because of his alignment with the ethos of the RSA, his willingness to take part in social change and professional position and expertise.
An RSA representative said: "A fellowship researcher read about Andy Tipping and his work as a tree officer. The RSA has a long association with tree-planting in the UK and we thought Andy would be interested to hear about our work. And by becoming a Fellow, he would be able to participate in a future environment project with other Fellows ... This wealth of expertise and knowledge is one of the Fellowship's greatest strengths."
