An analysis conducted by David L Strayer of Cary Institute for Ecosystem Studies shows that in the 20 years that Zebra Mussels (Dreissena Polymorpha) have been present in the United States, they have become one of the most dominant freshwater species. This comes at a huge expense to both native species as well as to humans. Even though the Zebra Mussel has had such a spectacular impact on the habitats in which it establishes itself, there are important questions that are still being ignored.
The economic expenses alone caused by the Zebra Mussel infestation are estimated at over $100 million. While this is a staggering amount, key policies have still not been passed or even proposed in order to keep the spreading of the Mussel at bay.
Public alarm associated with the expansion of the Mussel has driven technological and some policy advances, but much change is necessary to halt the spreading of the Zebra Mussel.
