4PLANET IMPACT / METHOD

Natural mangrove regeneration

Restore mangroves by improving site conditions so natural regeneration can occur.

How the method works

Shift from planting alone toward hydrological and ecological conditions that allow mangroves to regenerate naturally.

What the sources establish

• The UN profile says Sri Lanka shifted from mass mangrove planting toward creating conditions for mangroves to regenerate naturally after low sapling survival.

• The UN profile describes permeable natural-material structures that calm waves and trap sediment, creating conditions for mangroves to regenerate naturally.

Issues connected to this method

• Coastal ecosystem loss

Projects using this method

• Building with Nature in Indonesia
• Mangrove Regeneration in Sri Lanka

Where it may apply

• Degraded mangrove systems where natural regeneration is feasible

Limitations and risks

• Site hydrology, species composition and local disturbance determine whether regeneration succeeds.
