Phytophthora cinnamomi Rands is an exotic soilborne plant pathogen that is thought to have entered Australia with the early European settlers. It is now widespread across southern Australia, and along the east coast into the subtropics. It causes the most serious epidemic impacts on plant communities across a range of ecosystems. These include those areas with a Mediterranean climate where mean annual rainfall exceeds 600 mm (southwestern Australia, South Australia and southern Victoria); the temperate uniform, low elevated regions of Victoria and New South Wales; and in the winter-dominant rainfall areas in maritime climates of coastal and submontane Tasmania. For example, in the south-west botanical province of Western Australia approximately 2284 of the 5710 described plant species are susceptible to P. cinnamomi. In those areas where it causes epidemics it is considered a ‘biological bulldozer’ as it also impacts on many vertebrate and invertebrate fauna. Due to its threat to biodiversity and general ecosystem function it is considered by the Commonwealth Government’s Environmental Protection and Biodiversity Conservation Act 1999 as a ‘Key Threatening Process’ to Australia’s biodiversity.
