Lāna’i is the sixth largest of the main islands of Hawai`i. Over 200,000 years ago, Lāna’i was once part of Maui Nui a large island comprised of seven shield volcanoes.

As a result of erosion, rising sea levels and plate tectonics, this prehistoric island’s low valleys became submerged resulting in the islands of Maui, Moloka`i, Kaho`olawe and Lāna’i .

Though many native species have disappeared on Lāna’i due to overgrazing and extensive soil erosion, the last major remnant of the olopua/lama dryland forest that once covered large portions of the lowlands of Maui Nui still occurs on Lāna’i.
