The award was presented by Scotland’s minister for environment and climate change, Paul Wheelhouse, at Confor’s industry dinner.
Mr Yull has more than 50 years’ experience in the forestry sector, both in the UK and abroad.
Confor chief executive Stuart Goodall described Mr Yull as a "fighter and campaigner".
"He is a great champion of commercial forestry – articulate and relaxed on stage and in the media," Mr Goodall said.
