A year-long effort by residents of Bang Saphan to preserve the Mae Ramphueng swampland is about to bear fruit. The national environmental policy office has agreed to nominate the site as a national wetland. The villagers kicked off the campaign to register the 4,000-rai peat swamp, said to be Prachuap Khiri Khan's last pristine swampland, as a wetland of national importance last year. The move was part of a protest against plans by the steel giant Sahaviriya Group to build a smelting plant near the swampland.
