 A field study of the invasion of the pathogen "Phytophthora cinnamomi" into the Brisbane Ranges National Park in Victoria in 1971 indicated that "Epacris impressa" was moderately susceptible to the pathogen.Inoculation of seedlings confirmed this.Fieldwork in the Brisbane Ranges National Park in 1985 showed that there was some evidence that "E. impressa" seedlings were able to recolonise areas that had been infested with "P. cinnamomi" a decade before.
