Grant will be talking about recent improvements in habitat creation techniques, drawing on his work with ANU that involved the installation and monitoring of sixty chainsaw carved hollows. Reconciling risk management with conservation of tree habitat values will also be discussed, with case studies from urban parks in Melbourne.

Marty Harris will present some background on Gold Coast City’s mind-blowing success in habitat creation and detail data, tree selection for habitat creation, current university studies, lessons learnt for tree managers, and notable species’ success stories.
Marty aims to illustrate and discuss some challenges around politics and policy, and how to “blur, bend and break the rules” to develop a successful habitat creation program within an estate of urban trees.

Grant Harris

Grant first studied arboriculture at Merristwood and worked as a climbing arborist at the University of Oxford Botanical Gardens, where he became interested in the management of habitat in veteran Oaks.
After settling in Australia and completing a diploma in Arboriculture and degree in Environmental Science (Wildlife and Conservation Biology), he founded Ironbark Environmental Arboriculture.
Grant and his team provide arboricultural and ecological consultancy services to local government, industry and private clients; with a particular focus on habitat trees.
