Indeed, during the maximum glaciation at around 18 000 BC, south-west Europe may have served as a refuge area for Palaeolithic populations where the shift in the thermal gradient enhanced offshore fishing on the Cantabrian coast.It is about this time that probably some of the big game such as bison, wooly rhinocerus, and mammoth would have been hunted to extinction while the lions who hunted these prey became extinct also.The weather appears to have been considerably better than it is today as O'Kelly wrote: "In circa 9,600 BP, the Boreal Phase, birch was still present but hazel began to expand greatly.

It is quite possible that they may have brought pigs and goats because they could survive with little care in the coastal forests and they seem to do well together since pigs eat roots and tubers while goats can eat small twigs, branches and lichens.
The west coasts of Ireland and Scotland which presently have moors would have looked like forests since the warm gulf stream would not have had a full effect at this stage.
