PRELIMINARY RESULTS OF A PROVENANCE TRIAL OF EUCALYPTUS CAMALDULENSIS IN A DRY TROPICAL AREA OF NORTH AUSTRALIA

Abstract

A provenance trial of Eucalyptus camaldulensis was conducted in the Burdekin region of tropical north Queensland, Australia. Six provenances ranging from subtropical south Queensland to tropical north Queensland, each with and without mulch at planting, were assessed for their survival, height and DBH. There was a significant difference in survival, height and DBH among the provenances tested at age three years. However, the effect of mulch on these three parameters was insignificant. It appears that for the harsh environments of dry tropical north Queensland, provenances of tropical origins are more suitable than those from subtropical areas.
