Treasure of the Rio Grande Delta (VHS)

Twisting and turning from the Chihuahuan Woodlands to the Gulf of Mexico, the last 250 miles of this great river forms a rich delta... a transition zone between the semiarid tropics and the temperate north. Since the turn of the century, most of the delta's native vegetation has been lost but many small islands of endangered habitat survive at the edge of farms and cities. These islands harbor an incredible number of species... many endangered or threatened. Some are known only from the delta or reach their northern limits here. The delta is also an oasis... a stopping point for many birds on their annual migrations to the tropics and back.

John Bax spent two years chronicling the delta's wildlife and historic sites. His journey has taken him from the arid ranch country to rich Gulf estuaries. Many of the sights and sounds have never before been documented.
