Abstract
Introduction: Eucalyptus gomphocephala is a unique keystone canopy species endemic to a narrow (5-10 km wide) coastal strip approximately 300 km in length in the southwest of Western Australia. E. gomphocephala is undergoing a significant decline throughout large sections of its remnant distribution within Yalgorup National Park, and in some areas resulting in 100% mortality (Barber et al. 2007). Fine feeder root damage and root necrosis has been observed in declining E. gomphocephala across a range of sites. In addition, tree injection trials with phosphite, a chemical known to induce host defence responses to Phytophthora species, have resulted in increased crown vigour and health. These observations indicate that a Phytophthora species could be associated with tuart decline. The aim of the current study was to determine whether Phytophthora species are associated with E. gomphocephala decline.
