Niu at Famed Kapuāiwa Grove on National Big Tree Registry

Five Hawai‘i trees stand among the 64 newly crowned “Big Tree” champions across the nation on the newly announced 2016 American Forests registry.

Participation from local communities has helped the Hawai‘i Big Tree program locate some of the biggest trees of various species. This now increases Hawai‘i’s Big Tree count to 12 champion trees from Hawai‘i, Molokaʻi, and O‘ahu.

Hawai‘i island holds the record for champion trees, contributing 10 of the 12 national champions. In particular, Pu‘u Wa‘awa‘a Forest Reserve, now holds over half of the national champion trees from the state. With the enthusiastic participation from Pu‘u Wa‘awa‘a’s coordinator, Elliott Parsons, three more champion trees were located this year: a Lama, Kāwa‘u, and a Ma‘o hau hele.

Champion trees from other islands were also added to this year’s registry. In the historic Kapuāiwa coconut grove of Moloka‘i, a former co-champion Niu (Coconut Palm) takes the place of a fallen former champion coconut palm.

Oʻahu finally entered and crowned its first ever Big Tree champion: a Koki‘o ke‘oke‘o, or white hibiscus tree in Mānoa.

The Hawai‘i Big Tree program is sponsored by the Department of Land and Natural Resources Division of Forestry and Wildlife, and was created by the nonprofit organization known as American Forests.

The Big Tree program focuses on the largest trees of particular species, as a way to raise awareness about the importance of healthy trees and forests.

Since 1940, the American Forests National Big Tree Program has been able to keep the only national register of more than 705 champion tree species; However, it has only been within the last decade that Hawai‘i was able to contribute to the national register, focusing on native and Polynesian-introduced species.

There are a total of 19 eligible species from Hawai’i that are acknowledged by American Forests. This includes current and former champions as well as tree species that do not have a champion yet. The public is invited to explore and find new champions for all of these species. Tree nominations are currently being accepted and submissions for the 2017 registry will be due March 1, 2017.

The Hawai‘i Big Tree Competition does not have a champion for the following eligible Hawaiian species. Therefore, any tree nominated from the following list will likely be crowned a National Champion (listed by Hawaiian Tree Name/Genus & Species):

• Koki‘o ‘ula/Hibiscus clayi
• Nenelau/Rhus sandwicensis
• Lonomea/Sapindus oahuensis
• ʻŌhiʻa ʻai/Syzygium malaccense
• ʻŌhiʻa hā/Syzygium sandwicense
• A‘e/Zanthoxylum oahuense

To unseat a current champion, the challenger tree must have more total points based on the following equation: Total points = trunk circumference (inches) + height (feet) + ¼ average crown spread (feet).

To nominate a tree, contact the Hawai‘i Big Tree coordinator Krista Lizardi at (808) 587-0164 or [email protected] and provide the tree height, trunk circumference, and average crown spread. Also, applicants are asked to provide the tree’s specific location (GPS coordinates are appreciated).

Koa (Acacia koa) in Kona Hema Preserve, South Kona
(circumference: 343) (height: 115’) (crown spread: 93’)
