A study of pollen grains preserved in lake sediment can tell what kinds of plants were growing in
the landscape around the lake, which, in turn, tell us about the climate of the region when those
plants were alive. By pollen assemblage, we mean the number of various taxa of plants such as
trees, shrubs, herbaceous plants, and aquatic plants, and their relative abundance. Look at the
simplified pollen diagram (from sediment cored from a lake in the Lower 48) shown below and
interpret possible histories (climate, environment, human) of the region from CE 1600 to 2020.
Suggest as many possible interpretations as you like and be sure to describe your reasoning.
