What nutrient levels and loads need to be achieved in order to preserve the integrity of the ecosystem?

Part 3: Science guidance to management

Everglades Interim Report

Report available at http://www.sfwmd.gov/org/ema/everglades/previous.html
Many findings are also published in peer-reviewed scientific journals

  • Provides phosphorus concentration goals that treatment technologies must reach to prevent changes in native Everglades flora and fauna.
  • Identifies State water quality standards that could be revised due to unique characteristics of Everglades wetland.
  • Confirms that EAA Best Management Practices (BMPs) are achieving or exceeding phosphorus reduction targets.
  • Confirms that the design basis for Stormwater Treatment Areas (STA) construction was accurate.
  • Confirms that STAs will achieve or exceed phosphorus reduction targets, and will remove mercury.
  • Identifies advanced treatment technologies that combined with BMPs and STAs may reach phosphorus concentration goals.
  • Predicts that recovery of phosphorus impacted areas will take decades due to high internal loading from sediments.
  • Estimates that Florida Bay watershed P loads are smaller than Gulf, atmospheric, or Keys' inputs.


Science guidance to management

Surface Water Improvement and Management (SWIM) Plan
Many findings are also published in peer-reviewed scientific journals.
  • Identifies BMPs to optimize beef cattle production while minimizing surface water nutrient runoff.
  • Identifies impacts of phosphorus control practices and land uses on phosphorus delivery to the Lake.
  • Identifies basin-scale projects to reduce phosphorus concentrations in water entering the lake.
  • Quantifies relation between lake water levels, nutrient cycling, and ecological responses.
  • Indicates that lake response to external P load reductions will be delayed due to high internal loading from sediments.
  • Presents watershed and lake models used to predict lake responses to local and regional management actions (e.g., the C&SF Restudy).
  • Presents a comprehensive ecological monitoring program to track Lake ecosystem health.
