Invasive Species in a Globalized World

During the past quarter-century, public awareness about invasive species has reached unprecedented levels around the world, but a comparable transformation in policy is lagging. Basic knowledge about invasive species is still seriously lacking in multiple policy-relevant areas, notably risk assessment. Small-scale impacts justify the fight against invasive species, while biodiversity’s broad-scale resilience offers hope for restoration of habitats and native species. The piecemeal approach to invasive species policy needs a unifying framework, guided by an overarching ethic that transcends time and place in addressing the “appropriateness” of non-native species in our globalizing world. Such an ethic, while acknowledging that some invasive species become permanently embedded in ecosystems, must utilize species origin as its foundational principle, rather than species impact/benefit or ecosystem service. The development of a policy ethic for invasive species requires interdisciplinary collaboration, with ecologists in a leadership role.
