I've noticed this name crop up a bit recently. I dont know much about the man but I caught the end of a programme last week in which he was quoted quite a bit about the loss of the Grizzly and other predators. I found a link to it on BBCiPlayer.

Turns out it's only the last 10mins about him anyway
