Growing Green: How Parks and Trees Shape Honolulu’s Future

Honolulu’s urban tree canopy plays a crucial role in community well-being, environmental resilience, and cultural connection, yet coverage remains uneven across the city. Measuring tree canopy helps identify gaps and prioritize areas for planting, particularly in underserved neighborhoods where extreme heat and limited access to green space are significant concerns. Urban trees provide essential benefits, such as cooling streets, filtering air, reducing stormwater runoff, and supporting local economies. Parks serve as critical spaces for expanding tree canopy and fostering social, economic, and environmental benefits, reinforcing their role in urban sustainability.

As Daniel Dinell and Lea Hong highlight in this article, two notable examples of community-driven greening efforts are ʻAʻala Park and Makalapa Neighborhood Park. ʻAʻala Park, historically a hub for political and cultural activities, faced social and environmental challenges but is now being revitalized through a collaborative process led by Trust for Public Land. Partnering with local stakeholders and the University of Hawaiʻi Community Design Center, the project envisions a park featuring native plantings, agroforestry, and a community garden. Similarly, at Makalapa Neighborhood Park, youth advocates successfully pushed for increased amenities and tree planting efforts, demonstrating the power of grassroots involvement in creating healthier urban spaces.

These efforts highlight a growing movement to restore and enhance Honolulu’s urban forests, emphasizing the importance of community participation in reclaiming and greening public spaces. The city’s Department of Parks and Recreation, alongside nonprofit groups and engaged residents, is making strides in accelerating tree planting and park improvements across Oʻahu. As Honolulu celebrates the Year of Our Community Forests, residents are encouraged to take part in tree-planting initiatives, volunteer programs, and advocacy efforts. By taking action — one tree, one park, one person at a time — Honolulu can reverse urban tree canopy loss and build a more resilient, greener future.
