Biographical entry Kellas, John Douglas (1948 - )

Dr (PhD)

1 October 1948
Maffra, Victoria, Australia
Forest scientist


John Kellas has focused on forest pathology, studying the impact of Armillaria luteobubalina (Australian honey fungus) on forest regeneration and management. In his later career, he studied the effect of partial harvesting methods on the eucalypt species Eucalyptus obliqua and Eucalyptus radiata, and held several senior positions in the plantation management and forestry education sectors. He has recently been a forestry consultant in Vietnam.


John Kellas graduated from the Victorian School of Forestry, Creswick, in 1969. He joined the Forest Commission of Victoria, supervising thinning, harvesting and regeneration of native forests in East Gippsland. His research interest in the fungus Armillaria luteobubalina in native Australian forests led him to complete a Master of Science with a focus on forest pathology at University of British Columbia, Canada (1979). In Australia he continued his research on Armillaria and its impacts on the regeneration and silviculture of mixed species forests in western Victoria. He further established a study investigating the impact of partial harvesting methods on the regeneration and establishment of Eucalyptus obliqua and Euclyptus radiata. John Kellas then moved towards agroforestry and plantation management, holding senior positions at the Centre for Forest Tree Technology, formerly at the School of Forestry in Creswick, Victoria, where he managed plantation research and academic forestry training programs. From 2004-2009, he worked at the Green Triangle Regional Plantation Committee in Mount Gambier, followed by a General Manager position at Plantation Timbers Group, Mount Gambier. John Kellas was a forestry consultant at the Vietnamese Academy of Forest Sciences between 2011-2012..
