Resilience of Banksia woodlands to Phytophthora cinnamomi in the Walpole Wilderness Area, WA
Bishop, C., Wardell-Johnston, G. and Shearer, B. (2007) Resilience of Banksia woodlands to Phytophthora cinnamomi in the Walpole Wilderness Area, WA. In: 11th International Mediterranean Ecosystems (MEDECOS) Conference (2007), 2 - 5 September, Perth, Western Australia.
Introduction: Ecological resilience can be defined as the ability of a system to absorb a disturbance so that basic function and structure are retained. Resilience of a system is tested when impacted upon by a disturbance that has the potential to fundamentally and irreversible change the original identity of the system (Holling 1973; Folke et al. 2004). Plant pathogens playa significant role is determining vegetation dynamics at a range of ecological, spatial and temporal scales. However, there is little research on how plant pathogens change vegetation at a community and landscape scale. Phytophthora cinnamomi is an introduced invasive soil borne plant pathogen that is internationally recognised for its destructive impact upon native vegetation communities (Shearer and Smith 2000). Despite the pathogen being recognised as a Key Threatening Process, documentation of its impact on vegetation community composition, structure and function is limited. The pathogen is of particular concern in South-Western Australia where 40% of the flora is susceptible, of which 14% are listed as highly susceptible (Shearer et al. 2007).
