PALEOECOLOGICAL ANALYSIS OF AN ISOLATED STAND OF NOTHOFAGUS-CUNNINGHAMII (HOOK) OERST IN EASTERN TASMANIA

Pollen analysis of the sediments of a small bog, supporting a stand of cool temperate rainforest in southeastern Tasmania, was undertaken in order to examine the history of the stand dominant, Nothofagus cunnin ghamii, presently growing outside its predicted climatic range. The po llen record covers at least the last 9000 years and reveals changes in the bog and in the surrounding vegetation, although pollen percentage s of N. cunninghamii are sufficiently high to indicate that the specie s could have had a local presence throughout the recorded period. It i s likely that this N. cunninghamii stand is relictual, surviving not o nly Holocene climates, but also the cool dry conditions of the last gl acial period. This ability to survive changing and sometimes very unfa vourable climates leads to the conclusion that great caution must be e xercised in using present climates alone to predict the potential dist ribution of N. cunninghamii.
