To determine whether other species in kauri forest ecosystems are also susceptible to infection by P. agathidicida.
Forest composition varied between infected and non-infected stands. Detached leaf assays suggest lesion growth occurred on 6 native species of which reisolation detected PA in 3 of the 6 species (rewarewa; mingimingi; kauri grass). Visual symptoms occurred on Tanekaha when soil inoculated., however was not a significant impact.
