Thailand has many mangrove forests, but the Sirinart Ragini Ecosystem Education Center differs from other forests, as it includes an artificial mangrove forest that was invented by man. The soil is completely polluted, and in 1996, when King Rama XI and the Queen visited the Pranburi Forest Park, they were very concerned about the crisis of mangrove deterioration in the Pranburi Estuary, so he ordered the revival of this place, then the Royal Forest Department decided to cancel the use of this area for the shrimp field, In 1997 this forest was revived and planted in earnest, and now it is a lush green area abundant with animal habitats.
