    Species Notes for this Location:
    It is thought that Phytophthora cinnamomi was brought to Tasmania by European settlers. Buttongrass moorlands, heathlands and heathy understorey dry sclerophyll forests in western Tasmania are particularly susceptible to P. cinnamomi.
    Management Notes for this Location:
    Research is being undertaken in Australia to determine the effectiveness of fungicides in controlling P. cinnamomi. Management in Tasmania focusses on preventing P. cinnamomi from becoming established in areas in which it is not yet present, such as Maria Island. This oomycete has been listed as a threatening process in the Commonwealth Endangered Species Protection Act (1992), and a Threat Abatement Team has been established.
    Location Notes:
    Ecosystem change: Phytophthora cinnamomi causes severe disease in the understorey, or the shrub and ground layers of the vegetation in Tasmania. The susceptible species in Tasmania tend to come from the shrub and herbaceous families Dilleniaceae, Epacridaceae, Fabaceae, Proteaceae and Rutaceae. Resistant species generally belong to the grass and sedge families. The presence of P. cinnamomi can therefore lead to an understorey dominated by grasses or sedges.
