Biological Invasions: Recommendations for U.S. Policy and Management

Abstract. The Ecological Society of America has evaluated current U.S. national policies
and practices on biological invasions in light of current scientific knowledge. Invasions by harmful
non-native species are increasing in number and area affected, and the damages to ecosystems,
economic activity, and human welfare are accumulating. Without improved strategies based on
recent scientific advances and increased investments to counter invasions, harm from invasive
species is likely to accelerate. Federal leadership, with the cooperation of state and local
governments, is required to increase the effectiveness of prevention of invasions, detect and respond
quickly to new potentially harmful invasions, control and slow the spread of existing invasions, and
provide a national center to ensure that these efforts are coordinated and cost effective.
