Hawai‘i Big Tree Program
–Now accepting nominations for the 2019 season!
Please also see the new State Big Tree page here!
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, and to share their stories surrounding these trees. Can you find the next Big Tree Champion?
December 2017: Eleven Hawaiʻi Trees newly crowned as National Champions making a total of 18 National Champions from Hawaiʻi
Six Hawai‘i trees stand among the 109 newly crowned champions across the nation. Participation from local communities has helped the Hawai‘i Big Tree program locate some of the biggest trees of various species. This now increases Hawaii’s Big Tree count to 18 national champion trees from Hawai‘i, Molokaʻi, O‘ahu, and now Kauaʻi!
Enthusiastic participation from Entomology specialist, Karl Magnacca has helped locate ten more champion trees this year: an A‘ali‘i, Lonomea, Mānele, Nenelau, ‘Ōhi‘a ai, and ‘Ōhi‘a ha, including the following that have dethroned four former Hawai‘i champions: a Kāwa‘u, Kōlea lau nui, Ma‘o hau hele, and a Pāpala kēpau. Hawai‘i Island’s champion tree count is now 12 trees, the most of all the islands. O‘ahu is home to three new champions this year, a total of four national champions. The Kagimoto family has helped us crown Kauai’s very first Big tree champion: a 42-foot ‘Ōhi‘a ai with sweet fruit. Moloka‘i is still home to our 103-foot niu residing in one of the oldest and most sacred coconut groves in Hawai‘i. A huge Mahalo to those who contributed to this year’s big tree registry, as well as to those who have contributed in the past.
More information about these newly added trees as well the other seven national champions can be found in the links provided further below.
