The Role of a Project Arborist in Tree Management for Development Sites

A project arborist is a minimum AQF qualified Certificate 5 consulting arborist who specializes in the care and management of trees in the context of construction and development. They have the qualifications and experience as a consulting arborist to assess tree health and structure, understand species characteristics, and implement tree protection management plans in accordance with AS 4970-2009. Their expertise and qualifications as a project arborist ensure that both trees and development can coexist.

Key Responsibilities of a Project Arborist:

• Preliminary Tree Assessment
  A project arborist begins by assessing the health, structure and species of the trees on a proposed development site. They identify which trees can be preserved, which may need to be removed, and the best ways to manage those trees that will remain on site.
• Planning for Tree Protection
  Once the preliminary assessment is complete, the project arborist develops a tree protection management plan to protect the trees during construction. This will include but is not limited to TPZ site supervision, implementing tree protection fencing, developing strategies to minimize root disturbance and any additional construction supervision around trees.
• Compliance with Regulations
  Navigating local government laws and overlays regarding tree protection can be complex. Your Consulting Project Arborists should be well-versed in these laws and ensure that developers comply with all relevant regulations, helping to avoid potential fines, project delays or unnecessary damage to trees.
• Collaboration with Developers
  Effective communication is key. Project arborists work closely with architects, engineers, and construction teams to integrate tree protection management plans into the overall design. 

To ensure successful supervision of construction around trees, here are some best practices to consider:

• Involve a Project Arborist Early
  Engaging a consulting project arborist during the initial planning stages can lead to better outcomes for both trees and development.
• Conduct Comprehensive Assessments
  Understanding the health, structure, amenity and retention value of existing trees can guide decisions about tree protection and removal.
• Implement Tree Protective Management Plans
  Use tree protection zone (TPZ) fencing and other tree protection measures to protect trees from construction damage.
• Educate the Team
  Ensure that everyone involved in the project understands the importance of tree protection and follows the project arborist’s recommendations.

Project arborists play a vital role in balancing the needs of development with construction supervision around trees. By prioritizing tree protection management, we can ensure that our urban spaces remain vibrant and green. So, whether you’re a developer an architect or associated construction staff consider the impact of trees on your projects and the valuable insights a consulting project arborist can provide.
