Die Ontwikkeling van 'n Snoeibeleid vir die Vinnig Groeiende <i>Eucalyptus-soorte</i> in Staatsplantasies / The Development of a Pruning Policy for the Fast Growing Eucalypt Species in State Forests

SUMMARY The South African hardwood industry which is almost totally based on timber from eucalypt plantations, was initiated 102 years ago when a small eucalypt plantation was established near Worcester in the Cape Province. Today the Department of Forestry alone has reserved more than 14 000 ha for the production of hardwood sawlogs. In order to supply the sawmilling industry with high quality. defect free. sawlogs it was found necessary to prune the trees in state-owned eucalypt stands. The historical background and the principles considered in developing a suitable pruning policy are discussed. OPSOMMING 'n Suid-Afrikaanse Eucalyptus-loofhoutbedryf het 102 jaar gelede met die vestiging van 'n klein plantasie naby Worcester in die Kaapprovinsie begin. Tans is bykans 14 000 ha deur die Departement van Bosbou alleen, reeds aan die produksie van loofhoutsaagblokke toegewys. Om die saagblokke so defekvry moontlik aan die verwerkingsnywerheid beskikbaar te stel, is dit nodig geag om die borne in Eucalyptus-opstande te snoei. Die geskiedkundige ontwikkeling en formulering van 'n doeltreffende snoeibeleid word aangetoon en die beginsels wat daarby betrokke is, bespreek.
