This one should be quite an interesting one - I'm not entirely sure I can call which way it will go ultimately, as I think both collections are pretty strong in these categories! The topics at hand are TEMPERATE/BOREAL FOREST and MOUNTAINS AND POLES. Let the debate begin!
Bristol / Wildplace got my vote because of the brown bear as well as their wolves and wolverine. Though CWP have snowy owl, great grey owl and reindeer so I think they are close behind and only a point down from Bristol really for me.
