Koai’a (Acacia koaia)

Common Name(s): Koaia, dwarf koa, koa oha

Scientific Name: Acacia koaia

Distribution: Hawaii

Average Dried Weight: 70.5 lbs/ft3 (1,130 kg/m3)*

*Density based on a single sample tested

Janka Hardness: 3,250 lbf (14,460 N)*

*Estimated hardness based on specific gravity

Comments: Koai’a is very closely related to the much more commercially popular koa (Acacia koa). Koai’a grows as a much smaller, more obscure and gnarled tree (it’s sometimes called dwarf koa), not leading itself well to commercial harvesting. Also, the wood of Koai’a tends to be much heavier than koa (the single sample tested here was nearly twice as heavy as koa).
