Natural Habitat

Kauila is extremely rare and only found on the Big Island and on O'ahu, growing on the dry leeward slopes of North Kona and on the Wai'anae mountains. Kauila grows in dry to moist forests and is usually found by other plants like the lama.


Cultural Information

Kauila is native endemic to Hawaii, meaning it came to these islands by natural forces and can only be found here, not anywhere else in the world. Now this tree is almost extinct and can only be found on two islands, but was once used for many things by the ancient Hawaiians. Most of the Kauila plants have gotten to be extinct were that most of them have been killed off by brush fires. Using the hard, strong wood from the Kauila, the Hawaiians would construct heavy tools such as kapa mallets, poles, weapons, and fishing tools. There are two species of Kauila, this one, the Colubrina oppositifolia, and the Alphitonia ponderosa, which isn't as rare.
