This hand book has been produced from the results of wetland research projects funded by the Land and Water Resources Research and Development Corporation (LWRRDC) and Environment Australia, in association with the New South Wales Department of Land and Water Conservation (DLWC) and Botany, University of New England (UNE). The information contained in this publication has been published by LWRRDC to assist public knowledge and discussion and to help improve the sustainable management of land, water and vegetation. Where technical information has been prepared or contributed by authors external to the Corporation, readers should contact the authors, and conduct their own enquiries before making use of that information.
