"Island Reborn." Erosion has caused huge problems for the port of Baltimore as it tries to keep its busy shipping channels open. Each year, the Maryland Port Administration dredges several million cubic yards of mud from its winding waterways in the Chesapeake Bay. Until recently, there was debate and controversy about what to do with this dredged material.
Now the port believes it has found the answer. It's bringing back to life Poplar Island, which shrank from 1,200 acres in 1847 to five tiny islands in the early 1990s. The program explores the engineering, science and technology being used to build the new island into a wildlife sanctuary.
The reclamation of Poplar Island is one of the largest projects of its kind. "Island Reborn" shows how the island is becoming a wildlife oasis, and it looks at the larger lessons to be learned in how the busy ports around the world can clear their channels for shipping as well as help the environment by creating new habitat.

"The Root of It All." The nutria, a large, furry 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 National Aquarium in Baltimore missions -- 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.
