Summary

Researchers agree that preventing an invasive species from getting in is far and away the best and cheapest approach, but control measures can be politically sensitive, because exotic plants and animals are transported as part of international trade. Conventional wisdom once held that removing an already established exotic is all but impossible. But some scientists are becoming more optimistic that local invasions can sometimes be stopped--if they're caught in time.
