The Outdoor Circle's Exceptional Tree Map
For the past two years, The Outdoor Circle has traveled across the State collecting information about the Exceptional Trees of Hawai‘i. By obtaining a tree's: GPS coordinates, diameter, height, condition and photo, we have been able to compile an extensive database for these important specimens. In using this data, we have been able to generate the estimated environmental and economic benefits of these trees, in the hopes of educating the public of the immense benefits that all trees have not only on the environment, but also our daily lives.

As of now, phase one of the mapping of Oahu is complete and all of the neighboring Hawaiian Islands have been visited. A second more extensive visit to each will take place in the near future in order to obtain as much data from these Exceptional Trees as possible.

Future Updates:
1) Crown Spread
2) Live Crown Ratio
3) Electrical Savings (kWh)
4) Historical Information/Age of Each Tree
5) Revisit each tree to determine updated growth and condition.

The map is constantly evolving as new information is gathered, so please check back frequently!

*Note*- All Indian Banyan trees (Ficus benghalensis) have had their diameters calculated as accurately as possible. However, due to the extra trunks that form around the original one as a result of aerial roots, the diameters used for Indian Banyan trees in this map represent the closest values we could get to the central trunk using a diameter/measuring tape. In order to standardize this for all Indian Banyans, this meant including all trunks that we could not fit the tape between and thus could not exclude from the calculation of the tree's diameter. The exception to this is seen with the four Indian Banyan's at Thomas Square which had their data obtained from the Honolulu City and County's Draft Environmental Impact Assessment of Thomas Square.

​*Note*- The height and diameter for each tree on Maui was obtained using data from "Exceptional Trees of Maui County (2011)" produced by Maui County.

A Special Mahalo to all Who have Contributed to the Exceptional Tree Map!
