Nutrients

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


Part 2: Management challenges: how can science help?

  • Florida law states: "In no case shall nutrient concentrations of a body of water be altered so as to cause an imbalance in natural populations of aquatic flora or fauna."  What is an imbalance?
  • Which sources of nutrients are largest? most controllable?
  • Can nutrient sources be reduced to levels that will prevent imbalance?  How?
  • How long will it take for nutrient reductions to show a positive ecological effect?
  • How will the Restudy's goal of restoring more natural water levels and flows affect the fate, transport, and effects of nutrients in the ecosystem?


Questions that must be answered to provide a scientific basis for environmental management and litigation
Existing knowledge
graph
What are the biological impacts and what is an imbalance?


What sources are significant and why?


What nutrient reduction measures are succeeding, or are most likely to succeed?


How long will it take to see the effects of nutrient reduction, and what effects will other planned management actions have?
