Abstract: (Coastal drift sands used for exotic afforestation in the Auckland area exhibit a wide range of productivity. This is believed to be due to the influence of buried soils rather than variation within the sands. The sole species now used is radiata pine following experience over 28 years with several species. Stand development shows fast initial height growth with a mean top height averaging 83 ft at 20 years of age. Thinning regimes have shown extreme variation but basal area development trends are similar even in stands in which thinnings have been long delayed. Wood yields on sand are comparatively low, but operations are largely mechanized, costs low, and proximity to markets will ensure a good return.
