How can we know what kind of plants lived in the past in the Arctic? To understand the present, we need to know the past. In particular, to understand the current distribution of plants in the Arctic, you need to know the effects of the nearest past ice age on plants. What was the surviving plant at the edge of ice during the Ice Age? How did they expand their habitats in the Arctic after the last ice age? What was the plant that came to the Arctic as the Ice Age retreated and the ice disappeared?
