How well do phylogenetic studies inform the conservation of Australian plants?
Stephen D. Hopper Abstract Conservation of Australian plants depends on a spectrum of activities from descriptive and experimental biological studies to active management and restoration of wild ecosystems by local communities who value their native biota. On the basis of the premise that available resources for conservation will not allow for all threatened biodiversity to be saved, some systematists and conservation geneticists argue that phylogenetic relationships should be used to set conservation priorities. The principle advocated is that characters, not species number, should become the currency of conservation, that cladistic analysis of phylogenetic pattern provides a predictive means of modelling the underlying distribution of characters among taxa, and that priority should be given to that subset of taxa with the greatest number of character states. This approach has been applied for some time in the conservation of genetic resources within species (e.g. Eucalyptus caesia),
