Locals say their ancestors brought nipa palm trees from the Mekong Delta 200 years ago. Over the years, as people noticed their ability to protect the coast from erosion, strong waves and winds, more nipa palm trees were planted.
The nipa forest area was only around 3.5 hectares at the beginning. Today, the total area has expanded to 120 hectares.
The government has categorized nipa palms in Cam Thanh as a protected forest, which means they cannot be chopped down or otherwise exploited.
