More on George Monbiat's study of wolves in Yellowstone

I blogged earlier about a fascinating TED talk that George Monbiat gave concerning his studies into the amazing and widespread effects that occurred from the reintroduction of a very small number of wolves to Yellowstone National Park in the US. 

I have a particular personal interest in efforts around the world to try to reverse the negative impact of humankind on animal habitats. This issue was one of the themes in my novel The Wolf at the End of the World, and this study was both encouraging and counter-intuitive in many ways. Who would have guessed that bringing back wolves could impact the flow of rivers in an area?

If you are interested in this topic yourself, here is another shorter film on the same subject, narrated by Monbiat himself.
