NATURE - PBS VIDEO: 'FORTRESS OF THE BEARS' SNEAK PEEK # 2 - AIRS WEDNESDAY, JANUARY 25, 2012 AT 8/7C
It's taken all spring and summer, but the salmon finally return to Admiralty Island to spawn.
Alaska's Admiralty Island is home to an estimated 1800 brown bears, the largest concentration of bears in the world. Nearly 100 miles long and 20 miles wide, it is half the size of Yellowstone National Park, yet it sustains four times more grizzlies. The native Tlingít people call this island "Kootznoowoo," meaning "Fortress of the Bears." It is a place where bears depend on fish, fish depend on trees, and the trees depend on fish-eating bears to spread the nitrogen rich bodies of salmon throughout the forest. Everything depends on the annual salmon run. When a change in the weather keeps the salmon from arriving, the entire ecosystem is affected. Enter a world shaped by bears, trees, and salmon, and explores the delicate balance of their interconnected lives.
"Fortress of the Bears" premieres on PBS Wednesday, January 25, 2012 at 8/7c (check local listings) and is part of the 30th season of the Peabody and Emmy award-winning series.
