Abstract

Wildlife is intentionally and unintentionally translocated regularly carrying with it a range of parasites and pathogens. There are numerous examples of disease outbreaks originating from translocated animals. Managers of conservation projects, which involve translocating wildlife have a responsibility to protect humans, domestic animals, other wildlife and the ecosystem from negative effects of disease carried by the focus species. There is a significant lack of data available on the susceptibility, epidemiology and impacts of pathogens in wildlife populations making preventative actions challenging. Risk analysis has been developed to provide an objective, repeatable, transparent and documented assessment of the risks posed by a course of action. Standardised techniques have been developed and are utilised routinely to aid decision making. It is a tool used to guide policy making and disease control planning by governments and international organisations such as the OIE (World Organisation for Animal Health). Qualitative risk analysis is particularly useful in fields when quantitative data is lacking. Risk analysis has been developed for use in animal health risk management and subsequently adapted for wildlife disease management scenarios, cumulating in publication of the OIE/IUCN Manual of Procedures for Wildlife Disease Risk Analysis (2014). This paper considers further modification of risk analysis methods for wildlife translocations undertaken for conservation purposes. The challenges of these specific scenarios including hazard identification, multiple epidemiological pathways and data gaps are addressed and tools which could improve the usefulness of the technique, such as developing scenario trees and rating uncertainty are proposed.
