The effects of nutrient enrichment in the Florida Everglades are of considerable concern with regards to ecosystem restoration. The famed River of Grass is widely thought to have been a historically nutrient-poor environment. Today, however, the Everglades are subject to higher levels of enrichment from a variety of sources.
This five-year study involved constructing large-scale experimental phosphorus dosing stations in Everglades National Park. During the project period, ecosystem parameters were carefully monitored in response to specific concentrations up to 30 parts per billion (ppb). The study documented substantial changes in both periphyton and aquatic plant communities, and provides valuable insight into the recovery of marsh systems in the absence of continued enrichment.
