A >130,000 year-long pollen record from Pittsburg Basin, Illinois

Authors(s) and Affiliation(s)



Pittsburg Basin, in south-central Illinois, contains a sediment record extending from the present back to the end of the late Illinoian glaciation, when central Illinois was covered with Picea/Pinus forest. During the last interglaciation, a temperate deciduous forest more diverse than Holocene Quercus/Carya forest replaced the Illinoian late-glacial boreal forest. Prairie pollen types and the charcoal/pollen ratio, indicating fire frequency, temporarily increased. These changes in fire frequency could be caused by small changes in climate, human activity, or differences in soil
