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

The shellfish, shrimps and crabs that thrive in the environment were under threat a few decades ago after industrial shrimp farming left the mangrove forests decimated.

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.
