City arborist details tree removal and planting strategy amid construction pressures

The Wausau Parks & Recreation Committee convened on May 5, 2025, to discuss critical issues surrounding the management of the city’s urban forest, particularly in light of ongoing challenges posed by the Emerald Ash Borer (EAB) and urban development projects. The meeting highlighted the city’s strategies for tree removal, planting, and maintenance, reflecting a commitment to enhancing the community's green spaces.

A significant focus of the discussion was the management of ash trees, with the committee noting that 806 trees currently remain in the city that are not on the injection list for EAB treatment. These trees, often smaller or in poor condition, are monitored closely, and removals are prioritized based on their health and structural integrity. The city has seen an increase in tree removals, rising from approximately 800 to 900 annually, largely due to EAB infestations and infrastructure projects. In contrast, the city is planting around 525 trees each year, which falls short of the removals, creating a net loss in the urban canopy.

The committee also addressed the option for residents to pay for the injection of their ash trees, allowing some to retain their larger trees as long as they maintain treatment. This initiative reflects a community-oriented approach, accommodating residents who wish to preserve their trees.

In terms of planting efforts, the city has secured a contract with Legacy Trees, which has enabled the planting of 415 trees this year, exceeding initial projections. The committee emphasized the importance of equitable distribution of new trees across the city, ensuring that all neighborhoods benefit from the planting initiatives.

Another critical topic was the impact of street construction on tree preservation. The committee outlined a systematic approach to evaluating trees in construction zones, focusing on the health and stability of trees near excavation sites. Trees in poor condition or those that would be adversely affected by construction activities are marked for removal. The committee aims to balance the need for infrastructure improvements with the preservation of healthy trees, employing risk assessments to determine which trees can be saved.

Overall, the meeting underscored the city’s proactive stance on urban forestry management, addressing both the immediate challenges posed by EAB and the long-term sustainability of Wausau’s green spaces. As the city continues to navigate these issues, the committee remains committed to enhancing the urban forest while accommodating community needs and infrastructure demands. Future discussions will likely focus on refining these strategies and exploring additional funding opportunities for tree planting and maintenance.
