The City of Oshkosh's Sustainability Advisory Board convened on February 5, 2025, to discuss the critical intersection of landscaping practices and climate change. The meeting highlighted how local landscapes can be adapted to mitigate the impacts of climate change, emphasizing the need for immediate action to address rising emissions and their effects on the environment.

Key discussions centered on the projected increase in greenhouse gas emissions, which could rise to 1,200 parts per million if no action is taken. The board stressed that the severity of climate impacts will largely depend on the actions taken over the next decade. Localized adaptive strategies were recommended, as different areas face unique climate challenges. For Oshkosh, which experiences more extreme weather patterns, planning for both wetter and drier conditions is essential.

The presentation outlined several potential landscaping impacts due to climate change, including increased precipitation leading to soil compaction and reduced plant growth, as well as higher humidity contributing to plant diseases. The board noted that gardeners and landscapers will face more vigorous weed growth, necessitating increased pesticide use and management efforts.

To combat these challenges, the board proposed several sustainable landscaping strategies. These include using organic mulches, implementing drip irrigation systems, and replacing traditional lawns with low-maintenance grasses or sedges. The "No Mow May" campaign was discussed, with a recommendation for a modified approach that encourages higher mowing to promote deeper root growth and better drought resistance.

The board also emphasized the importance of planting native and drought-resistant plants, which can thrive in changing conditions. Trees were highlighted as a key element in reducing heat and energy consumption, with recommendations for diverse tree planting to ensure resilience against pests and diseases.

Additional strategies for managing heavy rainfall included the use of berms and rain gardens to direct water flow and improve drainage. The board advised careful plant selection to accommodate wetter winters and more freeze-thaw cycles, suggesting that residents consider winter mulching and proper placement of evergreens to prevent damage.

In conclusion, the meeting underscored the urgent need for Oshkosh residents to adopt sustainable landscaping practices that not only enhance local ecosystems but also prepare for the realities of climate change. The board plans to continue providing resources and education to help the community implement these strategies effectively.
