Impact of <i>Puccinia psidii</i> on M?ori taonga plant species

Abstract

Myrtle rust caused by the pathogen Puccinia psidii sensu lato is a disease of species in the plant family Myrtaceae that is not found in New Zealand It originates in South America but it has steadily spread around the world and is now found in Australia and New Caledonia While the potential economic and environmental impact of myrtle rust establishment in New Zealand has been well documented the potential sociocultural consequences including those for M?ori have not All New Zealand Myrtaceae species including indigenous species are at risk from P psidii infection but the potential impact on their health is not known All indigenous Myrtaceae species can be considered as Taonga (or treasure) by M?ori who have utilised the properties (eg spiritual medicinal construction tools food) of some species in many ways both tangible and intangible Optimally preparedness and response plans for a myrtle rust incursion in New Zealand should consider the unique spiritual and other values that M?ori associate with these plants
