We’ve been providing our consulting services around South East Queensland and further afield since 2007.

Our family has had a long history in arboriculture, starting in 2001 when Andrew and Alice Rankine purchased a tree services company.

Andrew immediately started applying his experience and practical problem-solving skills gained over the course of his 20year + career in business. After selling their tree services company in 2007, the Rankine’s launched Independent Arboricultural Services – a focused Arboricultural consulting business.

Since its inception, the company has continued to provide an independent, unbiased and professional arboricultural advice to provide the best possible solution, always proud to promote an educated arboricultural view supported by peer reviewed research from around the world and delivered using the latest methods and technologies.

Roger continues to drive these philosophies. He uses the management expertise, experience and technological skills gained during his 10yr+ corporate career to lead the Company into the next generation of technologies and service levels.
