Ecology of Eucalyptus aquatica (Myrtaceae) : a restricted eucalypt confined to montane swamp (fen) habitat in south-eastern Australia

  • The Paddys River Wetlands in the New South Wales Southern Highlands, southwest of Sydney, are characterised by several watercourses with associated swamps (fens), some of which, on Forestry Corporation of NSW land, have been the focus for removal of Pinus radiata wildings by the Penrose Swamps Conservation Group. In this study we map a population of Eucalyptus aquatica trees in one of these swamps perched above Paddys River (latitude 34.65575o S, longitude 150.21831o E; 600 m elevation). Eucalyptus aquatica is geographically restricted to the Paddys River area and is listed as a threatened species at state and national levels. New findings on the physical characteristics of the swamp in relation to the bedrock geology, stream geomorphology, peat development and the main native plant species, are presented. The occurrence of clumps of Eucalyptus aquatica appears to be independent of the type or thickness of the growing substrate. Rather it is suggested that a continuous supply of water and the shelter afforded by the narrow valley may be key factors determining the distribution of the trees at the study site. An on-going programme of research is underway to study other occurrences of Eucalyptus aquatica.
