Description
The most important forest tree is the koa (Acacia Koa) (…) and in abundance is probably second only to the ohia (o-hee-a). The wood of the koa is used for cabinet making and for construction.The ukulele, a mandolin-like musical instrument, is usually made of koa wood; and the ancient war canoes of the natives were hollowed out from the trunks of koa trees.
