Frogs: The Thin Green Line
Notes from the Director

Poison dart frog

Almost a year ago NATURE asked me to make a film about the disappearance of amphibians.  I’d made a film on that very subject 15 years ago, so I was a bit reluctant… for about a nanosecond.  Then I realized I couldn’t say no.

The fact is, since making my prior film dozens of frog species have disappeared -– and the decline of amphibians has escalated into one of the greatest environmental crises of our time.  Scientists are calling it the greatest mass extinction since the dinosaurs.  It’s HUGE!!!

The other reason I said yes is: I love frogs.

So, on a blustery day in April I began to piece together my stories… Since the crisis is global, that meant finding characters and frogs in spots as far away as Australia and South America, as well as right here in our own backyards.

The research was sobering.  Amphibians have survived for 360 million years and suddenly they’re vanishing…  I quickly learned that there isn’t any one culprit; frogs are getting hit from just about every direction: climate change, habitat loss, chemical run-off, introduced predators, over-collection, and deadly diseases… Basically, humans have stirred up a perfect storm for amphibians.

Over the next three days I’ll be posting more about my experiences with Frogs… Tomorrow: Panama (where we were faced the challenges of filming frogs in the middle of a wet jungle at night).  Hope you’ll come back…

    I wish you could do something to help us save a marsh that is part our 73 acre park that was deeded to the city in 1917. The developers admitted to not having done a full survey of amphibians/reptiles before deciding to put a Jack Nicklaus golf course golf tee in the marsh. Visit to help save our disappearing fragile ecosystems. Thank you for your incredible shows.

    I watched the show tonight and found it well done and informative, but sobering.I have been going out to ponds in Michigan for about 15 years and viewing frogs and salamanders at night with a flashlight. I hope my grandchildren can do the same. Thanks for bringing this crisis to the public.

    Best of luck to all the active conservationists out there. Your video tells a remarkable and important story that should bring us all pause to reflect on the practices of our modern society. Thanks for showing the world what is happening.
