Back when I was growing up I fished a lake in New England a lot as it was a little juant through the woods. Never ever saw a GBH. Last time I was there just a few years ago and there was a resident GBH. And there were a lot more frogs. Now hardly any frogs. I'm thinking the heavy DDT use back them may have eliminated them or reduced their numbers (GBH's) and the frogs didn't have a major predator.
