Propagation of ‘Iliahi (Santalum paniculatum Hook. & Arn.), a Valuable Endemic Hawaiian Sandalwood Species

Six Santalum species are endemic to the Hawaiian Islands where they are known locally as ‘iliahi. ‘Iliahi were once widespread throughout the islands, but most stands were harvested for the valuable heartwood, reducing the distribution by an estimated 90 percent. Limited natural regeneration and a burgeoning interest in ‘iliahi cultivation have prompted the need for reliable propagation systems. One species in particular, Santalum paniculatum, has been the focus of interest due to available planting area, relative abundance, and commercial-grade oil quality. We describe methods for seed harvesting, processing, germination, seedling transfer, growth, and field planting of S. paniculatum. These methods have successfully produced high-quality seedlings, although further research is needed.
