ArborCarbon scientists have been given the responsibility to design and implement vegetation monitoring programs that utilize a combination of in-situ and remote sensing method.
Native Australian trees at the school recreational camps provide very important shade and well-being to occupants, and habitat to numerous birds, reptiles and insects, but if sick can be a risk due to the presence of deadwood in the canopy, and can be expensive to maintain due to the need for ongoing removal and maintenance. A detailed Visual Tree Assessent (VTA) of the subject trees to identify structural defects and signs and symptoms of disease, and a Quantified Tree Risk Assessment (QTRA) of the subject trees utilizing available information on occupancy and calculation of the likelihood of failure, was carried out to determine whether subject trees or parts thereof were deemed to be above the threshold of the acceptable level of risk. In addition, soil and foliage samples were collected to enable the diagnosis of the causes of decline in health of the trees.
DELIVERABLES: The findings of this project resulted in the removal of anchor points and rope supports from trees, the accurate diagnosis of the cause of decline in health, and the implementation of treatments that mitigated further decline in health. Benefits include reduced risk of trees to occupants, improved health of the trees, and reduced costs for ongoing maintenance (i.e. pruning), and retention of the trees for future enjoyment. ArborCarbon has the knowledge and expertise to assess risk, diagnose and treat trees for ongoing sustainable management.
