Description :
A further 12 species of tree brave been identified from leaf fossils preserved in terminal Pleistocene-early Holocene lacustrine sediments exposed above the present shore of Lake Bosumtwi. Our earlier finding has been confirmed that forest was of Dry Semi-deciduous type, similar to the present-day forest of this area. The early Holocene forest may, however, have been more open than its modern counterpart. It is suggested that the relative openness of this forest may have been maintained by periodic invasion of fire from grasslands that formely bordered the forest. Continuous forest did not become established in the Bosumtwi area until mid-Holocene times (7500-5000 BP).
