Two pollen records were obtained, both at yearly intervals: a pollen-rain history (1975-84) and a record of past (1950-75) pollen accumulation, based on detailed 14C analyses of bomb carbon from finely-sectioned peat deposits. By matching these data with instrumental rainfall records at yearly intervals, recent pollen production and accumulation changes are related to short-term fluctuations in precipitation and fire occurrence. Comparisons between sedimentary pollen records and meteorological data show that the vegetation response, through pollen production and accumulation, was sufficiently sensitive to register short-term, low-amplitude changes in precipitation in the swamp sedimentary record. Related studies include charcoal particle analyses, fire scar surveys, and process modelling. -from Authors
