Why does Westeron moss grow on the south side of trees? Ours grows on the north because that's where the sun isn't.

What do Westeron mammoths eat? It seems there is little vegetation in the far north where they live. We think of mammoths as ice age creatures but they must have eaten like elephants only more so. Glaciers are scenic but not very nourishing so the mammoths must have lived well to the south of them and migrated up and down as the ice receded and advanced.
