A Pollen Analysis of a profile from the deepest part of the Kettlehole bog in the Cass Valley, Waimakariri River, yielded pollen which showed that there has been a change from grass-sedge association (with perhaps some trees), through a period when Podocarps formed one of the major elements of the forest, to the present predominantly Nothofagus forest. Inferences regarding climatic changes are not at variance with most results from other sources, except in that changes may have taken place earlier than believed by some workers.
