Hawai‘i Big Tree Competition Accepting Nominations for Spring 2021 Season
Nominations for the annual Hawaiʻi Big Tree competition are being accepted now through May 31, 2021. The competition aims to find the largest trees of native species and raise awareness about the importance of healthy trees and forests.
The Big Tree competition is sponsored by the DLNR Division of Forestry and Wildlife and nonprofit organization American Forests.
This year, the National Register of Big Trees represents 644 species across 45 states and the District of Columbia. Currently, the American Forests database has 22 champion tree species eligible for nomination in the State of Hawai‘i, including one new champion tree species for the state: the false kamani (also known as the tropical almond). Thirteen of Hawaiʻi’s champion tree species are endemic to Hawaiʻi, meaning theyʻre found nowhere else in the world.
Hawaiʻi has 19 current champions of the 22 species available that were found and nominated by the community as the largest trees of their species. Three elusive trees-the Aʻe, Kokiʻo ʻula, and Wauke, have yet to be crowned in the Hawaiʻi Big Tree competition. If nominated, one of these trees will likely be crowned a national champion.
To replace a current champion, the challenger tree must have more total points. Points are calculated using trunk circumference, height, and crown spread measurements.
Total Points = Trunk Circumference (inches) + Height (feet) + ¼ Average Crown Spread (feet).
If you would like to nominate a tree, contact Hawai‘i Big Tree Coordinator Brayden Aki at 808-587-0164 or email: [email protected] and provide the tree height, trunk circumference, and average crown spread, as well as the tree’s specific location (GPS coordinates are appreciated). The deadline for nominations is May 31, 2021.
