Abstract
Surface sediments were collected at 30 sites in a large freshwater coastal wetland complex situated in and around Rondeau Provincial Park, southwestern Ontario, Canada. Vegetation was described using a Braun-Blanquet scale of percent cover in 5x5-m quadrats centred on each sediment sampling point. The observed wetland plant communities were sharply zoned and in close proximity to each other. The sampling sites were clustered into several groups of vegetation communities. The objective of this study was to determine whether these communities have distinctive pollen signatures or if local pollen deposition in a large wetland complex is homogenous. Sediment samples were analyzed palynologically. Multivariate statistical analyses on the pollen counts showed that the pollen signatures from different wetland plant communities can be differentiated. These findings were used to interpret fossil pollen spectra found in sediment cores taken at this site. A number of local shifts in wetland plant communities have occurred during the Late Holocene, suggesting a possible influence of both allogenic and autogenic factors on coastal wetland development.
