Biological Invasions ProgramBiological invasions—the introduction and spread of exotic organisms in regions outside of their native range—has emerged as a major environmental, economic and public health problem tied to the rapid, ongoing expansion in international trade and travel. Recent studies have found that exotic organisms constitute the second greatest threat to biological diversity, ranking below habitat loss and degradation but far above pollution and over harvesting. SFEI's Biological Invasions program conducts scientific and policy research and provides information and analyses on the introduction of exotic organisms into marine and freshwater ecosystems.
