Abstract

Analysis of dispersed organic matter (palynofacies) and palynomorph data for the Bray Conservation Area Lake show low levels of pollen, high levels of spores and fungal matter, and increased opaque content from a depth of ~10-18cm. This suggests that some kind of major disturbance occurred in the recent past. This event may be related to the clearing of Missouri forests in the late 19th and early 20th centuries. The results of this analysis will be used to try to understand the nature of the disturbance and ascertain whether or not the disturbance is related to the clearing of forest. If possible, it will also be compared to Carbon-14 dates obtained from the core to establish the true time relationship.
