Hawai'ian Eucalyptus (Eucalyptus Robusta): Originally from coastal areas of eastern Australia, this species was introduced to the Big Island of Hawai'i for reforestation when cane and cattle farms began to shrink. It grows in plantation stands on the Hamakua coast on the eastern side of the Big Island. These stands are managed by the Kamehameha school district of Hawai'i, which has released permits to harvest as lumber. Proceeds from this release go back into the school district's programs for the benefit of Hawai'ians.
