The fight against Phytophthora dieback in Western Australia

home-page-photoPhytophthora dieback is the biggest threat to biodiversity in Western Australia and has now spread throughout the south-west from Eneabba to Esperance.

Phytophthora dieback is a deadly, introduced plant pathogen and is unusual as it has animal, fungal and plant characteristics. Scientifically known as Phytophthora cinnamomi, it is classified as a water mould belonging to the new ancestral kingdom Chromista.

Phytophthora dieback lives in soil and attacks the roots of many native plants. It also destroys animal habitats and threatens whole communities.

Banksia communities are particularly susceptible - dieback can turn a flourishing woodland into a sparse sedge-land.

Humans are the main culprits for spreading dieback, especially over large distances and although there is no effective cure for the pathogen, its spread can be controlled.

Dieback can slowly move itself through autonomous spread by swimming through the water in soil and growing through plant material. Some animals are also associated with its localised spread.
