Marion Whitmann, Asian Clam Expert (Part 1)

Dr. Marion Whitmann is an expert in Asian Clams which are an invasive species in Lake Tahoe. These clams don’t have any natural predators in Tahoe and as a result have taken over significant swaths of the lake floor where they cause damage to the ecological system and can sometimes cause economic damage by spurring algae blooms and other effects damaging to Tahoe’s water and beaches.
