Rich,I live up here 365 days a year and see elk on at least a weekly basis and watch them regularly.I also hunt in areas where there's a relativelyhigh population and I've never seen them in a thicket of oak browsing.I can take you up to Evans fire tower road where we'll most likey find elk tracks and none of them will be in the oak regeneration.They'll be in the fields along 255 grazing.They do occassionaly browse but they graze alot more than deer do.When the snow is real deep,you can see where they strip the bark off of aspen and red maple but that is a far cry from competing with the deer.They won't and can't strip the bark off of oak.There is no comparison to the damge deer do to seedlings as compared to elk.The reason it isn't documented is because it's minimal.
