Abstract

A method to determine the climatic requirements of tree species is outlined and related to the concept of multidimensional niche. The Bioclimate Prediction System devised by Nix, Busby and Hutchinson is used to analyse the bioclimatic component of the ‘realized niche’ of the species. The bioclimatic component of the ‘fundamental niche’ is then estimated using data from field trials outside the natural range. The method is demonstrated using the following eucalypt species: Eucalyptus citrodora, E. cladocalyx, E. fastigata, E. globulus spp. globulus, E. gomphocephala, E. grandis, E. maculata, E. paniculata, E. regnans, E. resinifera, E. robusta, E. sideroxylon and E. tereticornis. The bioclimates of their natural distributions in Australia are compared with conditions at trial sites in Africa. The method offers an explicit procedure for describing bioclimatic requirements and should assist the selection of appropriate species for trials.
