The Koa Tree
The reddish wood is highly prized for use in wood carving, musical instruments, and furniture. Its trunk was used by the ancient Hawaiians to build dugout canoes. Koa is also a tonewood, often used in the construction of ukuleles, acoustic guitars, the Hawaiian steel guitar and longboards.
The Koa is one of the fastest growing trees in Hawaii. It can grow up to 20 feet in 5 years, however, it takes 50 years for the tree to become full grown adult and at a point where it could actually be used for what people want it for. If you own land in abundance in Hawaii at about a 3500 foot elevation you could generate a nice income for your property by farming Koa Trees. Besides they are beautiful trees.
