Abstract

The pollen within a short core from Blackhawk Lake shows the impact of settlement in the area. The proportions of both ragweed and pigweed pollen increased while the proportions of total arboreal pollen decreased. Among the arboreal pollen types, oak and hickory decreased while elm increased. These changes in the pollen record need to be recognized when samples of modern pollen are used to aid the interpretation of fossil pollen.
