Abstract

Few, if any, data exist on below-ground biomass for most plant communities. Nevertheless, the proportion of plant productivity devoted to root growth may be substantial. The major difficulties in obtaining representative measures of root biomass are: i) Obtaining samples which are representative of the root zone, especially with respect to depth; ii) Adequate separation of the root material from soil minerals without loss of live material; and iii) The discrimination between live and dead material. Wetlands soils tend to be poorly consolidated so that some of the above problems are partially alleviated. This paper reports on the determination of below-ground biomass in parts of the intertidal wetlands at Pelican Point near Sydney, and on Kooragang Island near Newcastle. Among Australia intertidal wetlands, root biomass estimates are available for mangrove stands in the Lane Cove River, New South Wales (Briggs, 1977) and in Westernpoint Bay, Victoria (Clough and Attiwill, 1975) and a Juncus kraussii wetland in Western Australia (Congdon and McComb, 1980). In this paper we present data for similar sites and for adjacent Casuarina glauca woodlands and Sarcocornia quinqueflora saltmarshes.
