Key Takeaways:
- Potential issues with tree removals following severe stormy weather in the South have been highlighted in a new report
- The report expresses concern about the management of Invercargill’s Otepuni Gardens after wild winds in October
- The council is considering removing trees at two reserve areas and replanting, with a cost of $500,000
- The decision aims to address public safety concerns due to the proximity of trees to key roads
- Climate change projections suggest an increase in the frequency and severity of storms, contributing to tree failures
Introduction to the Issue
The recent severe stormy weather in the South has raised concerns about the management of trees in public spaces. A new report by arboriculture consultancy Paper Street Tree Company has highlighted potential issues with tree removals in Invercargill’s Otepuni Gardens. The report, written by company founder Richie Hill, expresses concern about the significant ground disturbance and torn root from machinery at the site. Hill notes that the focus on tree removal has overtaken consideration for long-term impacts on retained trees, and warns that "overzealous" tree removal will be harder to defend if adequate controls are not in place.
Concerns About Tree Removal
Hill’s report also takes issue with the work carried out on the tree canopy in the gardens, saying it has left poor structural outcomes and load transfer issues. The report suggests that the council needs to show that difficult choices are being made with a retention-first approach, and that the removal of trees should be carefully considered. Hill notes that replanting has the potential to be a better outcome if there is a robust planting plan or vision, but emphasizes the need for careful decision analysis to weigh the costs and benefits. The report’s findings have sparked concerns about the management of trees in public spaces, particularly in areas with high foot traffic and proximity to key roads.
Upcoming Council Decision
On Tuesday, the Invercargill City Council committee will receive Hill’s report and meet to discuss reserve areas with large trees near the Otepuni Gardens. One option put forward is to remove all the trees at those sites and replant, with a cost of $500,000. The decision aims to address public safety concerns due to the proximity of trees to key roads, particularly at the intersections of Elles Rd and Tay St, and Queens Drive and Don St. The council is exploring two options for responding to the risk: remove and replant, or activate emergency controls such as road closures in the event of weather warnings. The council’s decision will have significant implications for the management of trees in public spaces and the balance between public safety and environmental considerations.
Tree Health and Risk Assessment
Hill’s previous report from 2024 noted that a section of trees opposite Mitre 10 in Elles Rd were in "very good health". However, the new report acknowledges that some tree failures are unpredictable, and that the perceived risk of trees is often much higher than the actual risk of harm. The report highlights the need for careful risk assessment and management, taking into account the frequency and severity of storms, which are projected to increase due to climate change. The council’s decision will need to weigh the risks and benefits of tree removal and replanting, and consider the long-term implications for the health and safety of the community.
Climate Change and Tree Management
The increase in frequency and severity of storms due to climate change is a contributing factor to tree failures, and the council’s decision will need to take this into account. The report notes that there have been several significant tree failures in the city area over the past seven years, but none have led to a fatality. However, the council’s approach to tree management will need to adapt to the changing climate, and consider the potential risks and benefits of different approaches. The decision to remove and replant trees, or to activate emergency controls, will have significant implications for the management of trees in public spaces and the balance between public safety and environmental considerations.
Conclusion
In conclusion, the report by Paper Street Tree Company has highlighted potential issues with tree removals following severe stormy weather in the South. The council’s decision will need to carefully consider the risks and benefits of different approaches, taking into account the long-term implications for the health and safety of the community. The management of trees in public spaces is a complex issue, and the council’s approach will need to balance public safety concerns with environmental considerations and the potential risks and benefits of different approaches. As the frequency and severity of storms increase due to climate change, the council’s approach to tree management will need to adapt and consider the potential implications for the community.
