About the document
Australia’s native plants and ecological communities are threatened by the soil-borne plant pathogen, Phytophthora cinnamomi, for which it is estimated over 2000 plant species are known hosts (Shearer et al 2004). P cinnamomi is present in all states and territories of Australia and causes disease in an extremely diverse range of native, ornamental, forestry and horticultural plants. Described as a ‘biological bulldozer’, P cinnamomi is destroying bushlands, heathlands, woodlands and forests, which are the habitat for rare and endangered flora and fauna species. ‘Dieback caused by the introduced plant pathogen Phytophthora cinnamomi,’ is listed as a key threatening process under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act).
This background document complements the statutory Threat Abatement Plan (TAP). The TAP outlines the actions proposed to abate the threat and addresses the statutory requirements of the document. This background document provides supporting information on matters such as the biology of the pathogen, its population dynamics, spread, diagnosis and impacts on biodiversity and management measures.
