INHS Affiliate and former director of the Illinois River Field Station was featured on CBS Sunday Morning in a story about invasive species. On the Asian Carp, Sass stated "We've seen explosive population growth, a population that has almost doubled every year. We're fairly confident we have the highest wild densities of Asian carp anywhere in the world." David Lodge of Notre Dame says studies estimate that invasive species cost the US Economy on the order of at least $120 billion annually. There are 30 federal agencies involved in the fight against invasive species, with about $1.5 billion spent annually. Education and prevention are key to warding off the invasive species.
