Abstract: Mensurational investigations into the magnitude, persistence and extent of a possible decline in productivity of radiata pine in its second rotation on Moutere gravels in Nelson were carried out using detailed stem analyses on individual trees from both first and second crops. In some few areas, there have been marked drops in height, basal area and volume growth of the second crop, but in most others the drops are small and on still others none is apparent. Sometimes the apparent drops in productivity are permanent, but mostly they are transitory and confined to the first 5 to 8 years in the life of the second crop.
