    Abstract

    Temperate upland peatlands on sandstone (called upland swamps) are an endangered ecological community under several State and Federal policies. These systems are prevalent in the Blue Mountains west of Sydney. There is significant interest in understanding the geomorphic structure, evolution and condition of these systems so that better management decisions can be made about swamp conservation and rehabilitation. In the Blue Mountains, upland swamps have been forming and accumulating mineral sediments and organic peats for some 13,000 years. Intact systems in good geomorphic condition have high water table levels, are characterised by preferential drainage lines, are unincised, contain hydrophilic vegetation associations and form peat over the long term. Unfortunately in the Blue Mountains, many of these systems have been incised and urbanisation is having a significant impact on their condition. Successful reinstatement of swamps in areas Where they are degraded or dewatered requires techniques that can be designed with the potential to recreate or trigger the redevelopment some of the ‘natural’ structures and processes that operate in these systems.
