Containment and eradication of Phytophthora cinnamomi within a native ecosystem in the Fitzgerald River National Park
Dunstan, W., Scott, P., Hartley, R., Paap, T. and Dunne, C. (2010) Containment and eradication of Phytophthora cinnamomi within a native ecosystem in the Fitzgerald River National Park. In: Dieback Information Group Conference ('10), 16 July, Perth, Western Australia.
In contrast with most other large reserves, the Fitzgerald River National Park (FRNP) remains relatively unaffected by Phytophthora cinnamomi. However, several discrete infestations are located well within the body of the park and are significant threats. In 2009 a series of small infestations were identified off Pabelup Drive in the western side of the park. The Pabelup infestation may have been established in 2003 and is likely to be less than I ha in extent. We have demonstrated experimentally that we can eradicate P. cinnamomi in some sites with similar vegetation and/or climate (Dunstan et al. 2010). At the Pabelup site we will modify and scale up the approaches that were used experimentally, in an attempt to initially contain, and then eradicate, P. cinnamomi. The site has significant management challenges that include: difficulty in mapping the occurrence of the pathogen; surface water movement; variable site characteristics, in soils, topography, vegetation and hydrology; and, animal vectors. An adaptive management approach has been utilised that will employ additional new techniques to manage the site, including: feral animal fences; elevation models and hydrology projections; and, geo-textile membranes to capture inoculum of the pathogen in surface water.
