Hawai‘i’s Big Tree Competition

UPDATE: Hawai‘i’s newest Big Tree National Champion is a 40 foot wiliwili tree (Erythrina sandwicensis) located in the Waikoloa Dry Forest on Hawai‘i Island. The impressive Big Tree boasts a total score of 237.84 points.


Run by American Forests, the National Big Tree competition seeks to find the biggest tree species in the United States to promote and preserve our tree species. In Hawai‘i, our goal is to educate the public about our native and culturally valuable tree species. Currently the State of Hawai‘i has twenty-one tree species eligible to be crowned a National Big Tree Champion, listed below. The Champion Big Trees are measured based on a point system designed by American Forests using their height, circumference, and crown spread. We encourage the public to join our search for the biggest tree of each of these species. Can you find the next Big Tree Champion?
