I don't recall that conclusion. I don't believe that was there, but I would have to read it again. I think what was acknowledged was that when you look at the habitat needs of the boreal caribou, you see that they need large tracts of land, and it's not enough to think about, for example, the calving islands that you want to protect. You have to think about the range of the caribou, but that does not equate to “you can't do anything inside that range”.
They did quite a bit of work on demonstrating the relationship between the level of disturbance and the recruitment rates for the boreal caribou, i.e., the survival rates, to demonstrate that the higher the disturbance inside a range, the less likely the caribou would persist into the future.
