In 2003 IACA was formed as a national organisation by professional Consulting Arboriculturists. Membership comprising qualified practitioners concentrating on the provision of advice about trees to the public, all levels of government, anyone managing trees, and the building industry. It was founded to support and promote the professional interests and ongoing development of Consulting Arboriculturists in Australia and their specialised services providing objective and unbiased advice to the community for managing urban trees.
The Institute’s primary aim is to foster practice and research in support of the Consulting Arboriculturist, through professional standards detailed in the IACA Code of Ethics which members agree to be bound by. As well as promoting the role of the Consulting Arborist, IACA’s mission is to maintain the highest standards of practice, promote uniformity within the profession, support the ongoing professional development of members through training, education and networking opportunities, and to address tree management issues, educational and industrial issues which affect the profession.
