Read moreExceptional knowledge about trees, environment, legislation and policy. Mark, the AQF Level 5 arborist who attended the property, provided a clear and balanced report outlining how environmental values and policy often fail to align in urban tree management. His observations highlighted the risks of indiscriminate canopy reduction while remaining measured and professional in a way that supports constructive dialogue.

Read moreMark Hartley was quite easily the best arborist I have worked with in his capacity as an expert witness in the Land and Environment Court. After our initial consultation on one matter Mark was kind enough to inform us where his services would not be beneficial to the client's case and saved that client a substantial amount of money. Mark is unique given the combination of commercial acumen, technical expertise and professional reputation as a respected expert in the Land and Environment Court. It was fantastic working with you Mark!

Read moreI have used the Arborist Network for more than half a decade to conduct audits on the safety and condition of trees sited on our education facility. Mark Hartley has attended on every occasion and his extensive knowledge of aboriculture is very evident and validates him as a leader in this field. He is also very generous in sharing this knowledge and engaging Mark and the Arborist Network for aboricultural consultation work is a decision which has greatly benefited our organization.

Read moreMark Hartley is the best practical arborist in Australia. In order to achieve a positive result for our DA Mark literally was in the trenches and covered in dirt to ensure that critical trees were accurately assessed, their roots mapped and their prospects of survival methodically estimated. With his passion for trees and his ability to challenge outdated standards and norms we successfully achieved a result far beyond our expectations. 2 years after Mark had advocated care for two trees that council stated would not survive, the trees are thriving.
