The project by three R&D corporations – Rural Industries Research focuses on selecting species that can be developed to and Development Corporation (RIRDC), Land & Water supply feedstock for the large-scale markets of wood Australia (LWA), and Forest and Wood Products and energy products. The first phase of the project Research and Development Corporation (FWPRDC)1, has produced three reports: together with the Murray-Darling Basin Commission (MDBC). The R&D corporations were funded principally a) Evaluating agroforestry species and industries by the Australian Government. State and Australian for lower rainfall regions of southeastern Australia governments contributed funds to the MDBC. (FloraSearch 1a) Significant financial and in-kind contributions were b) Agroforestry species profiles for lower rainfall also made by project partners within the Cooperative regions of southeastern Australia (FloraSearch 1b) Research Centre for Plant-based Management of 2 c) Review of wood products, tannins and exotic Dryland Salinity and SA Department of Water, species for agroforestry regions of southern Land and Biodiversity Conservation. Australia (FloraSearch 1c). This report, a new addition to RIRDC’s diverse range This report provides background information and of 1800 research publications, forms part of our methods from three supporting studies undertaken Agroforestry and Farm Forestry R&D program, by project partner Ensis/CSIRO Forestry and Forest which aims to integrate sustainable and productive Products. The first study is an assessment of wood agroforestry within Australian farming systems. testing protocols and results. The second study Most of our publications are available for viewing, evaluates tannin as a product and its potential downloading or purchasing online through our website: market. The third study addresses the possibility n downloads at www.rirdc.gov.au/fullreports/index.html that species from around the world, in similar climatic regions, could be useful crop species and presents a n purchases at www.rirdc.gov.au/eshop review of this option. The rationale for this last study Peter O’Brien was that although the FloraSearch project has Managing Director focused on an evaluation of native species, it Rural Industries Research and recognised that there is a vast pool of unexploited Development Corporation genetic material overseas of unknown commercial value and which is potentially well suited to domestication in Australia. 1 Now Forest & Wood Products Australia (FWPA) 2 Now Future Farm Industries CRC (FFI CRC) Foreword iii Acknowledgements The authors acknowledge the Joint Venture The input and helpful advice of project collaborators Agroforestry Program and Murray-Darling Basin and members of the FloraSearch Steering Committee Commission for funding this project, and the support is gratefully acknowledged.
