This seminar will present research and information on Phytophthora Dieback and Marri Canker, two plant pathogens that significantly threaten native plants in south west Western Australia.

Date Friday 7 April
Time: 9.15 am – 12.00 pm
Venue: Biological Sciences Lecture Theatre, Murdoch University
Cost: $30 per person (morning tea provided)
Register by: Wednesday 5 April

Phytophthora dieback and marri canker, threaten the health of native trees and contribute to a decline in biodiversity of natural areas. Dieback caused by the root-rot pathogen (Phytophthora cinnamomi) is listed as a key threatening process.   It causes the most severe and widespread damage to native plants in Western Australia and is commonly spread by construction activities and the use of infected plant stock, soil and mulch in our urban landscapes.

The impact of canker disease (Quambalaria sp.) on the iconic marri (Corymbia calophylla) is of serious concern.  It poses a considerable threat to marri, a keystone tree species of south-western Australia’s global biodiversity hotspot.  It appears that infected trees do not recover from marri canker infection, and important research is being undertaken to better understand the disease syndrome, and possible relationship between it and Phytophthora dieback.

Environmental managers, planners, landscapers and community leaders are invited to this professional development seminar on the management of Phytophthora dieback and marri canker.  The seminar will assist local government staff and community leaders to understand the environmental impact of these pathogens and develop strategies to better manage current and future infestations.

This seminar is part of the Professional Development in Environmental Management series produced by Perth NRM.  For further information and to register please go to alternatively email
