Managing biological invasions is a worldwide endeavor that aims to (a) prevent the human-caused spread of species, (b) control and remove unwanted species, and (c) reduce negative impacts to society and the environment. These efforts range from local-scale removals of weeds and pests to international policy frameworks attempting to curb the re-distribution of species in terrestrial, wetland, freshwater, and marine environments. The old adage that ‘an ounce of prevention is worth a pound a cure’ is often wisely highlighted in policy directives, but the reality of invasion ecology requires policy makers and environmental managers to respond to established invaders as well. The cumulative cost of invader impacts exceed billions of dollars per year in lost revenues and human health, creating great incentive for prudent policies and effective management.

At SERC, we conduct research to evaluate the efficacy and consequences of invasion management strategies and policies across different ecosystems --- from forests and marshes to coastal estuaries.  Our work is often done in collaboration with local, state, federal and international partners and used actively to inform current management and policy decisions.
