"Oysters." At the turn of the 20th century, oyster harvests from the Chesapeake Bay numbering in the millions of bushels were commonplace. Last year, harvests approached just 23,000 bushels. Oysters are responsible for filtering the Chesapeake's water. This segment explores the latest efforts of scientists and policymakers as they attempt to determine whether to release the Asian oyster, keep the native Chesapeake oyster in place or wait until more studies are completed.

"Piercing the Forest." Department of Natural Resources wildlife biologist Dave Brinker goes to the steep and rocky slopes of the Western Maryland mountains to track down what he believes to be the only nesting pair of goshawks in the state, fit the birds with expensive tracking transmitters, and return them to the safety of their treetop nests.

"Planet Chesapeake." Using data from the Earth Observing System of satellites, scientists at the NASA-Goddard Space Flight Center in Greenbelt are compiling data on topics that directly influence the climate and ecology of the Chesapeake Bay watershed: sea surface temperature, deep ocean temperature, rainfall, hurricane anatomy, sea level rise - and an array of other subjects. This segment looks at the Chesapeake on a planetary scale.

"Trust in the Land." In the Chesapeake Bay watershed, farmlands are increasingly recognized as bulwarks against a rising sea of concrete. Land trusts are playing a vital role, helping government agencies protect cultural lands, forests, wetlands, open space, wildlife habitat and fertile farmland.

"Rat's Room with a View." The woodrat lives hidden in the mountains of west-central Maryland. This small brown rat is an indicator species that tells scientists a lot about the health of other animal species and even forests.
