An economic approach to assessing import policies designed to prevent the arrival of invasive species: the case of Puccinia psidii in Hawai'i

► We assess the economic impact of a ban on the import of non-seed Myrtaceae. ► Three sectors were considered in the study: florists, nurseries, and plantations. ► Expected benefits to plantations outweighed costs to other affected industries. ► Including the value of 'ōhi'a protection would increase the benefit-cost ratio.
