Abstract: The history of re-establishment methods used up to 1966 is traced. The movement of logging on to high altitude flat sites necessitated a radical change in re-establishment techniques. The limitations of artificial and natural seeding methods were established by studies of seedling growth and mortality after air sowings in 1966 and 1961. As control of early silvicultural operations became more precise, considerable deficiencies were noted in areas of natural regeneration which had previously been considered adequate. A photographic study illustrated the highly variable nature of natural regeneration and showed that it cannot be relied upon to restock any area completely.
