We use transect quadrant method to get the data of density, frequency, dominance, important value index, and diversity index of mangrove. The coast community behavior that brings positive and negative impacts to the mangrove ecosystem was known by using interview and observing method. The result shows that there are 3 kinds of mangrove in this place. The average of diversity index in each location is less than 3.2, shows that the mangrove forest was in the condition of depressed, that caused by negative behaviors of coast community, i.e., illicit timber, waste disposal in coast area, the manufacturing of irrigation channels, and the conversion from mangrove forest area to cultivation and salt ponds area. Even though, some people also participate in the governmental or non-governmental organization program for planting and conserving mangrove.
