Ironwoods

Ironwood typically refers to Casuarina spp. (e.g., Casuarina equisetifolia) found along coastal and windy areas. On Hawaiʻi Island, stands of Ironwoods serve as windbreaks or erosion control plantings in coastal or drier upland zones.

Ironwoods

Ironwood is dense and can be challenging to work, hence its name. Although historically used for fuelwood, fence posts, or small-scale craft (since it resists rot to an extent), it is not a major commercial timber on Hawaiʻi Island. Often, Ironwoods are left standing to protect crops from wind or to stabilize soil. When removed, the wood can be milled but is prone to warping if not cured carefully. Most Ironwood usage remains opportunistic, lacking a large market due to milling difficulties and the species’ function as a protective windbreak.
