Come to the sanctuary’s latest in the Sanctuary Cinema Series! Lake Huron, one of the five parts comprising the Great Lakes, has been hit with numerous exotic species invasions over the last century. Each invasion changes the ecosystem in ways we can’t predict. Fish populations have collapsed, the entire food web completely altered, and a multi-million dollar industry has dried up. Biologists are racing to understand these changes and restore balance to the third largest lake in the world before the next invader arrives (2009 film by John Schmit, 56 minutes, no rating). Free and open to the public.
