Arboricultural Association chief executive Karen Martin said: "Mike put much personal time and effort into the association as a trustee and while chairing the professional committee in 2010. Much of the work on Trees in Towns II, the barriers report with Jim Smith and British Standards review committees was also down to Mike. He was indomitable."
NATO administration officer David Williams said: "Mike could work with anybody. We will never find someone with his enthusiasm and drive."
