The protection of Antarctic ecosystems from alien and invasive species is one of the key aims of the Environmental Protocol (1991) to the Antarctic Treaty System. Despite the patchy nature of different domestic policy implementations and management strategies regarding this issue, recent research has shown that the threats of biological invasions in Antarctica are real. Introductions of nonnative and invasive species in the Subantarctic Islands provide a useful analogue for discussing the potential risks in the Antarctic Peninsula and continent. The increase in human activities and their subsequent logistics support provides increasing opportunities for alien species to hitch-hike to the Antarctic, and for the dispersal of indigenous species around the continent. Moreover, rapid environmental changes the Antarctic Peninsula in particular may provide nonnative species with the environment they are looking for and contributes to the complexity and uncertainties involved. Regardless of the overall lack of knowledge and ill-defined scope of this problem, precautionary measures need to be taken urgently.
