Peat bogs; Soils--Composition


The vegetation on a bog located in Kane County, Illinois was studied. Interpretations of the bog were also made from aerial photographs of the area taken in 1939 and 1961. The strata of the peat were sampled for the types of pollen found in them and from this data, assumptions of the earlier vegetation types that covered the area around the bog were made. The peat was analyzed and correlated with the vegetation studies. An interpretation of the results from the pollen analysis cannot be definite. Rather assumptions are made based upon the trends interpreted from the frequency of the various genera of tree pollen. Four major plant associations and two minor associations were observed on the peat during the recent studies. Changes since 1939 in the size and composition of the associations are discussed. The ecological succession has been directed by the lowering of the water table and the responses among the different associations to this event. The amount of decomposition that is occurring in the peat is related to the successional stage under which it is found. The development of the bog followed the classical interpretation of bog succession. However, the succession from the heath seral stage to the climax oak forest is presently occurring at an accelerated pace because of the drop in the water table.
