The project will monitor water quality, soil, periphyton, and plant dynamics in the Southern Everglades. This project will continue and build on data collection occurring since 1996, using consistent approaches and methodologies. Collectively, monitoring of these ecosystem components at all of the stations will allow scientists and managers to continue the establishment of pre-restoration baseline conditions, to better assess and establish ecological performance measures that are relevant, and to assess the water quality and ecological impacts of hydrological restoration planned through several projects, including the Comprehensive Everglades Restoration Plan (CERP), Modified Water Deliveries, C-111 South Dade Project, and changes that may occur through implementation of the Combined Structural Operation Plan (CSOP).
