"Increased sedimentation is widely cited as an important stress for Caribbean coral reefs. However, for most locations we currently lack both accurate records of changes in sediment accumulation rate over reefs as well as a quantitative link between land use practices and downstream sediment yield. This study aims to provide this information for two watersheds in Saint Lucia. We modified a GIS-based sediment budget model originally developed in Saint John (US Virgin islands) to calculate current and past sediment yields in the two focal watersheds, and used sediment cores collected near downstream coral reefs to examine changes in sediment composition and accumulation rate over the past several decades. Our results show increases over the last decades in accumulation rates of terrigenous sediment, originating from the upstream watersheds, as well as calcareous sediment, likely arising from the decline of corals. Changes in sediment yields over time calculated with the model were similar to changes in terrigenous sediment accumulation rate on the reef, suggesting that this simple model hasgood potential as a predictive tool"--Abstract.
