Narrated by Peter Thomas (Nova), EDGE OF THE EVERGLADES: BIG CYPRESS NATIONAL PRESERVE tells the story of the massive, mysterious marshland that continues to inspire deep passions for - and bitter debate about - one of the last great wild places in the world. On the western edge of the Everglades, beyond the sawgrass prairies of the famed River of Grass, lies the cypress-studded marshland known as the Big Cypress Swamp. The vast wet wilderness - a mosaic of marshes, cypress trees, pinelands and prairies once slated to house the world's largest jetport - now stands as a testament to compromise. In 1974, unlikely allies - conservationists and hunters - brokered a controversial deal which attempted to satisfy both environmental and recreational interests.
