"Chino Farms." The largest land set-aside deal in Maryland's history has created a living laboratory in Kent County on the Eastern Shore. The 5,200-acre Chino Farms is now home to a number of natural resource experiments, which include restoring an ancient prairie and the sparrows that once lived there.

"Last Stand at Shady Side." They say it was Tropical Storm Agnes in 1972 that started the long, slow decline of Chesapeake Bay and the way of life of so many watermen who fished the bay. Then MSX and Dermo infected the oyster bars and the water got worse. The grasses started to disappear from the bottom and then the crabs and fish left. Now watermen from the Western Shore have gathered together at Shady Side to see if the Chesapeake - and their way of life - can be saved.

"Sawhet Owls." DNR ecologist Dave Brinker travels the state to find, capture, tag and release as many of these tiny owls as he can. Brinker's annual census of the bird will help resource management officials track the population and migration numbers of the species.

"Night Falls Softly." Every autumn, thousands of chimney swifts come to roost in a huge old chimney in the Hampden section of Baltimore. This urban site is one of the top 10 for chimney swifts in the eastern United States. Why these birds have abandoned hollow tree trunks for human-built chimneys in a matter of a century or two remains a puzzle of the natural world.

"A Leg Up." In Howard County, a stable of horses offers the disabled improved health and happiness.

"White Marlin." The white marlin is considered by anglers one of the top game fish in the world. Fishing for it brings millions of dollars in tourism revenue to Maryland alone. But researchers have warned that the white marlin may soon be listed as a threatened species. The DNR sets out on a daylong expedition to the Gulf Stream waters of the Baltimore Canyon 70 miles east of Ocean City to see for themselves just how prevalent white marlins are.
