Land ownership
Land comprising the Mauna Kea mamane-naio forest IBA is owned almost entirely by the State of Hawaii. Some of the land is leased to the U.S. Army as part of the Pohakuloa Training Area. Onwership information was unavailable or unlisted for 8% of the area. Less than 1% of the land is privately owned, and these lands are narrow slivers on the edges of the IBA.
