Coastal mangrove removal fails to stop estuarine mud-infilling. Reducing upstream sediment supply is key to restoring coastal ecosystems, as mangrove removal can unexpectedly increase sediment trapping. Holistic management is essential.
Area of Science:
- Coastal geomorphology
- Ecosystem restoration
- Bio-morphodynamic modeling
Background:
- Upstream land-use changes significantly impact downstream coastal ecosystems globally.
- Coastal restoration often overlooks landscape-scale processes crucial for success.
Purpose of the Study:
- Investigate the effects of increased sediment and mangrove removal on estuarine morphology.
- Evaluate the efficacy of mangrove removal for estuarine restoration.
Main Methods:
- Utilized an idealized bio-morphodynamic model based on New Zealand estuaries.
- Simulated impacts of deforestation-driven sediment increase and mangrove removal.
Main Results:
- Mangrove removal initiatives do not mitigate estuarine mud-infilling or restore sandy ecosystems.
- Mangrove removal unexpectedly enhances estuary-scale sediment trapping.
- Only reduced upstream sediment supply effectively limits estuarine muddification.
Conclusions:
- Bio-morphodynamic feedbacks have contrasting local and estuary-scale effects.
- Human interventions like vegetation removal can yield counterintuitive results, hindering restoration.
- Holistic management approaches are necessary for effective estuarine restoration.
