Wolves are a top-line predator.
I understand you helped direct the program that reintroduced wolves to the United States, after years of extinction. Well, we needed wolves that knew how to make a living in an area like Yellowstone National Park. So we contacted the governments of Alberta and British Columbia and asked if they had any wolves to spare. So we did that and sure enough, there were a lot of wolves. In Alberta, we worked with local trappers who normally trap wolves for the pelts.
