That's real interesting. I never appreciated the destructive nature of deer. So, deer hunters and wolves, I thank you.
Two Things:
1) It's minor but those are Elk, not deer. It's not a big deal but it bugs me that that video gets the taxa wrong.
2) I don't think that human hunters have the same behavioral effect on elk and deer that wolves have had. Human hunters definitely changed Elk/deer behavior by pushing them to be nocturnal, but their space use and food consumption were not modified so much. This difference is partly because human hunters hunt Elk/deer (mostly) visually, not by smell, and humans don't hunt at night because of laws and because we just don't see that well at night, so the deer shifted their peak activity to be after dark. Also, it's partly because we hunt deer everywhere they are, not just in the riparian habitats at the bottom of valleys, where they hangout because of all the good food...if they started leaving those valley bottoms to avoid us hunters, humans would follow with equal effort, where as wolf-packs set up territories and hunt what ever comes to them ... people shoot deer where ever they are so we don't have the spatial effect on their behavior. I just want to be clear about this so that we don't start thinking, 'we should hunt deer in all the national parks!' Wolves, as presented in this video, have a unique and very hard to mimic effect on the ecosystems they inhabit.
