The City of Mandurah has initiated specialist preservation works to protect one of Greenfields' most recognizable natural landmarks—the cherished Big Tree. Estimated to be over 200 years old, this tuart tree stands at the intersection of Pinjarra Road and Old Pinjarra Road.
Significant Tree Register
Listed on the city’s significant tree register, the Big Tree is recognized for its outstanding visual presence, ecological value, and deep cultural and community importance. Following the discovery of a significant structural crack, the city engaged specialist arborists and structural engineers to assess the tree and determine the safest long-term management approach.
Previous Preservation Efforts
As part of earlier preservation efforts, approximately 30 percent of the canopy was carefully removed in 2022 to reduce weight and stress on the trunk, while still maintaining the tree’s overall health and character. The next stage of works, scheduled to start in May, will see the installation of a certified specialist support system designed to further improve the tree’s structural stability.
Support System Details
The system will include static cables and textile straps, along with minor adjustments to the adjacent footpath to support the works. These measures are expected to significantly extend the tree’s life.
Community Commitment
Mayor Amber Kearns said the project reflected the city’s commitment to caring for the places the community valued most. “Trees like the Big Tree are more than just part of our landscape—they are living landmarks that hold memories, meaning and connection for our community,” Ms Kearns said. “We know how special this tree is to local residents, and that’s why we’ve taken a careful, expert-led approach to ensure it can continue to be enjoyed safely by future generations.”
Residents are encouraged to take note of any temporary changes in the area during the works, with impacts to traffic and pedestrian access expected to be minimal.
