Tree City Communities

The Arbor Day Foundation’s Tree City program provides the framework necessary for communities to manage and expand their public trees.  Hawaiʻi has proudly been participating in the program since the program’s inception with our first community, Maui who joined in 1976.  Participation in the program has grown since and we continue to welcome new communities each year. Today, Hawaiʻi boasts ten Tree City USA communities, including:

Tree Campus K-12 Communities

The program fosters positive connections between youth and the trees in their community and cultivates within its participants a lifelong respect for trees on a global scale.  Local student Anna Learner ’22 led efforts to establish Punahou School as the first Tree Campus K-12 community in Hawaiʻi in the programʻs first year! Le Jardin Academy (LJA) student Zoe Wiechmann completed Kaulunani’s “My Tree Campus” challenge as part of the Hawaiʻi Youth Sustainability Challenge; a collaboration between Kupu and Kōkua Hawaiʻi Foundation.
