I have been all over the slope and have seen the "Damaged" tundra. The old trails did change the tundra. It compacted it I suspect and maybe led it to some thawing. But is it really damage or diversification. The old roads that thawed now support willows where before only tundra tussocks grew. Lord knows there are plenty of tussocks everywhere up there. There is no shortage. I think the over all effect of having the "willow roads" is more positive than negative. If the tundra thaws, willows will already be there to seed the area and capture the green house gases that will be released. Moose may thrive. Maybe polar bears will come ashore and hunt moose. Maybe there will an overall positive benefit to this area. Drastic changes have happened here on earth over the eons and long before man. Somehow the earth always seems to find or produce life forms that benefit from almost any change. Expecting the earth to never change is denial. It will change. Think positive. Barrow renamed Miami.
