Layers may also be applied to the basal epicormic shoots of adult trees . Some eucalypts (such as E nitens) lack lignotubers, and must depend on the epicormic buds for regeneration. If the majority of the trunk has been removed as harvested firewood then so too have most of the epicormic buds on which the tree would normally depend. Many species of angiosperms found in fire-prone areas of Australia and South Africa exhibit this specialization. A plant which once appeared dead can, within a season of growth, have a greater amount of growth and biomass. In some plants, there is further protection whereby both heat and moisture are required to release the seeds. ex Rodway, Pap.
