Economic Analysis of the Proposed Rule to Prevent Arrival of New Genetic Strains of the Rust Fungus Puccinia psidii in HawaiÔi
Since its first documented introduction to HawaiÔi in 2005, the rust fungus P. psidii has already severely damaged Syzygium jambos (Indian rose apple) trees and the federally endangered Eugenia koolauensis (nioi). Fortunately, the particular strain has yet to cause serious damage to ÔohiÔa, which comprises roughly 80% of the stateÕs native forests and covers 400,000 ha. Although the rust has affected less than 5% of HawaiiÕs Ô?hiÔa trees thus far, the introduction of more virulent strains and the genetic evolution of the current strain are still possible. Since the primary pathway of introduction is Myrtaceae plant material imported from outside the state, potential damage to ÔohiÔa can be minimized by regulating those high-risk imports. We discuss the economic impact on the stateÕs florist, nursery, landscaping, and forest plantation industries of a proposed rule that would ban the import of non-seed Myrtaceae plant material and require a one-year quarantine of seeds. Our analysis suggests that the benefits to the forest plantation industry of a complete ban on non-seed material would likely outweigh the costs to other affected sectors, even without considering the reduction in risk to ÔohiÔa. Incorporating the value of ÔohiÔa protection would further increase the benefit-cost ratio in favor of an import ban.
