West of the West is a documentary series on the fascinating human history of California’s Channel Islands. Produced for public television, these 3 one hour programs contain 13 compelling “Tales” - from the original inhabitants over 13,000 years ago to those who discovered, shipwrecked, developed, restored, and were abandoned on these wild and beautiful islands.

f you want to see a wild island fox, you have to visit the remote Channel Islands off the coast of Southern California. This special species doesn't live anywhere else.

Biologists were alarmed in the mid-'90s to discover that these foxes had suddenly and mysteriously started to disappear. In 1993, more than 1,500 had roamed the largest of the islands, Santa Cruz. By 2001, fewer than 100 remained. Extinction seemed imminent. But why?

A band of allies that included public and private organizations, ecologists, veterinarians and volunteers got together to figure out the path of ecological missteps that had led to the fox's decline. It all traced back, through a couple of twists and turns, to a pesticide developed by the Allies in World War II.

The team's journey to set things right included helicopter chases, an elite hunting squad from New Zealand, a remote-controlled egg and lots of determination. This is a conservation story with a high cost but, ultimately, a happy ending — something almost as rare as the island fox.

Over the course of hundreds of scuba dives, marine biologist Ayana Elizabeth Johnson fell in love -- with a fish. In this ode to parrotfish, she shares five reasons why these creatures are simply amazing (from their ability to poop white sand to make colorful "wardrobe changes") and shows what's at stake -- for us and them -- as climate change threatens the future of coral reefs.
