View new conceptual models illustrating important stressors affecting your waterways: Stressor models are used to show how human activities (i.e. threat models) interact with the natural processes occurring in an estuary (i.e. process models) and impact the ecosystem. This allows pressure and condition indicators to be determined that are specific to a particular stressor and estuary type.
A set of 13 defined stressor models were identified by:
- pH (changed from natural) model
- Aquatic sediments (changed from natural) model
- Connectivity (changed from natural) model
- Biota removal/disturbance model
- Nutrients (changed from natural) model
- Freshwater flow regime (changed from natural) model
- Habitat removal/disturbance model
- Hydrodynamics (changed from natural) model
- Litter model
- Organic matter (changed from natural) model
- Bacteria/pathogens model
- Pest (plant, animal) species model
- Toxicants model
