Species prioritization index for oiled wildlife response planning in New Zealand

Abstract

Birds are extremely vulnerable to the effects of oil pollution. For wildlife, prevention of oiling is the best response option, however if not feasible, the fastest response gives the highest chance of survival. Therefore, the development of an oiled wildlife preparedness plan based on analysis of areas at risk, vulnerable species and potential response options is critical. This research developed an area based, species priority index (SPI) for New Zealand birds to guide oiled wildlife planning. The SPI shows significant areas of New Zealand's shoreline and offshore islands have many highly vulnerable species that need careful consideration given restricted response options available. Identification of these areas and species allows priority planning for placement of personal and equipment. This SPI can be adapted for other species (marine mammals and reptiles) and for other geographical areas to help develop response plans for oil pollution and oiled wildlife response worldwide.
