How replanting mangroves helped bring back shellfish

The Samut Songkhram province of Thailand has seen an amazing transformation in its ecosystem.

But a massive mangrove-planting campaign - which had royal backing - has helped restore the area which is now part of the Khlong Khon Mangrove Conservation Center.
