*As we purchase several different sub species of Ironbark, and there are variances among them in several areas, Outlast have chosen the lowest specifications for the species as a whole for its technical specifications. Ironbark may reach a seasoned strength group of between SD3 and SD1. Generally speaking, Ironbark is also generally resistant to Lyctus Bore, however, there are some sub species that are indeed susceptible.
