"Colonel Lee's Birdhouse." Fort Carroll, south of the Key Bridge, was begun in 1847 to stop any attempt to invade the port of Baltimore.

U.S. Army Brevet Col. Robert E. Lee had high hopes for the fort when he oversaw its construction, but it never saw action and was never even completed. Now, it has become home to a world-class nesting-bird rookery.

There is a problem, though: The trees that provide nesting cradles may be threatening Fort Carroll's structural integrity. But the offending trees can't be cut because state law protects the rookery. The quandary: Save the fort or keep the birds?

"Clear to the Bottom." The water of Chesapeake Bay must be clean and clear enough for sunlight to reach the bottom if sub-aquatic grasses are to grow. They provide a living, protective nursery for aquatic animals like fish and crabs. For now, the water isn't clean enough in most parts of the Chesapeake.

Scientists say it won't be until filter feeders like oysters return in high enough numbers to remove sediment and excess nutrients. Scientists are experimenting with methods to replant grass beds.

"Brush and Feather." John Taylor is a popular and successful Chesapeake Bay artist and conservationist.

"Spring's Wings." Richard Smith, Maryland's reigning expert on butterflies, travels the state with experts from the Maryland Department of Natural Resources in search of species common and rare, and with the hope of getting a fix on how Maryland's butterfly population is faring.
