Baseline information

Much of the information about plants naturalised in Western Australia is drawn from the checklist compiled by Greg Keighery in 1994 (Keighery, 1995), that listed 1032 vascular plant species as naturalised in this State. This was the first modern overview of the State's weed flora. Since its publication, additional plants have been recorded as having naturalised and there is every reason to expect that further plants will naturalise in the years ahead. [Ref: Keighery, G.J. (1995). An Annotated List of the Naturalised Vascular Plants of Western Australia. In: G.R. Burke (editor) Invasive Weeds and Regenerating Ecosystems in Western Australia: Proceedings of the Conference held at Murdoch University, July 1994. Institute for Science and Technology Policy, Murdoch University, Murdoch].

Financial support

We would especially like to thank the Plant Protection Society of Western Australia for conceiving the project, obtaining a grant and asking us to assemble the text.  Finally, very sincere thanks to the organisations that provided funds to enable the project to proceed. To the Western Australian Lotteries Commission and the Trustees of the Gordon Reid Foundation for Conservation, for a major grant. To Agriculture Western Australia for a substantial cash contribution and employee time. To the Department of Conservation and Land Management for employee time.  Despite the unstinting help that we have received, it is likely that some errors will remain. These are the responsibility of the authors.
