Ecological conceptual models: a framework and case study on ecosystem management for South Florida sustainability

Area of Science:

• Environmental Science
• Ecology
• Conservation Biology

Background:

• Everglades and South Florida ecosystems face significant degradation and threats.
• Ecological risk assessment, sustainability, and adaptive management are national frameworks for ecological assessments.

Purpose of the Study:

• To demonstrate the application of ecological risk assessment and adaptive management principles at a regional scale.
• To evaluate future management options for degraded ecosystems through scenario analysis.

Main Methods:

• An effects-directed assessment approach combining retrospective eco-epidemiology and prospective risk-based assessment.
• Development of integrated conceptual models linking societal actions, environmental stressors, and ecological effects.
• Scenario analysis to project risk reduction and system recovery, including quantitative performance criteria.

Main Results:

• Conceptual models were developed to explain current ecosystem conditions and guide future management scenarios.
• The study outlines a framework for assessing stressors and developing performance criteria for ecosystem recovery.
• The approach integrates societal goals with scientific analysis for decision-making.

Conclusions:

• The demonstrated approach provides a robust framework for regional ecological risk assessment and adaptive management.
• This methodology can guide decision-making for the recovery and sustainability of complex ecosystems like the Everglades.
• Integrating conceptual models and scenario analysis is crucial for effective ecosystem management and policy development.
