Mussels once numbered the millions in the Ohio River. Now researchers are hoping to find a type of salamander that an endangered mussel needs to survive.
Despite efforts to contain it, the insect has spread to neighboring states. The Secretary of Ag says it's invasive "economically, socially, and environmentally."
When you start out in birding, you get yourself a good pair of binoculars, a guide to birds, and some sturdy footwear. But something else you want to have is a mentor.
Mussels are a natural filter, cleaning up muddy water and allowing more sunlight into the water. A new hatchery hopes to raise a half a million mussels a year for the Delaware and Susquehanna watersheds.
