F. Biodiversity: Invasive Species

This Website has moved to a new and improved location:

Hope you can join us there!

Background Readings:

Discussion Questions:

  1. Using the field guide of Aquatic Invasive Species in the Susquehanna Watershed, are there any invasive species that could be transferred between waterbodies during water transportation to the well site?
  2. If you look at the current USGS map of zebra mussel distribution in Pennsylvania, New York, and West Virginia, which watersheds have the highest occurrence of zebra mussel sightings? How does this compare to drilling activity in Pennsylvania or your state? Visit the USGS Zebra Mussel and Quagga Mussel Information Resource page for additional maps. 
  3. Can you think of ways to prevent the transport of invasive species in water trucked to the well drilling sites?

The cost of controlling aquatic invasive species in the U.S. is estimated to be $120 billion per year!
