"The Root of It All." The nutria, a large South American animal introduced to the Eastern Shore of Maryland to bolster the fur trade, escaped years ago into the wild and ate thousands of acres of precious marsh grass. A recent report says that the nutria has been eradicated from Blackwater National Wildlife Refuge's fragile tidal ecosystem.

"Journey of the Longnecks." In years past, numbers of Canada geese in Maryland were down. Experts at the Maryland Department of Natural Resources blamed poor weather at the birds' northern nesting grounds and even overhunting. Now, new management programs are helping the population grow.

"Flying to Freedom." Volunteer Mary Graul flies her airplane on missions for the National Aquarium in Baltimore -- whether to release baby sea turtles that have been rescued and nursed back to health or to carry experts skyward to get a count of dolphin populations off Ocean City.

"Stompin' the Swamp." An ancient swamp in Calvert County brings out the curious and hearty as young and old alike stomp through the swamp to find the granddaddy cypress of them all.

"Buy a Landslide." Calvert Cliffs is the site of a classic environmental conflict. What's more important -- the federally endangered tiger beetle living in the cliffs, the people whose homes are in danger of falling into the Chesapeake Bay as the cliffs erode; or the rare fossils regularly found in the cliffs? Who goes and who stays?

"A Wild Dinner." A mountain man of Garrett County origin leads the Outdoors Maryland viewer through the woods and meadows as he collects ingredients for a wild dinner.
