【 摘 要 】

This study aims to determine vegetation characteristics and micro-climate of rehabilitation mangrove forests at East Sinjai District, Sinjai Regency. The results showed that mangrove forest rehabilitation had a complete vegetation structure, consisting of seedlings, saplings, and trees, with the level of vegetation diversity included in the "low" category. Overall, there are 18 types of mangroves at the rehabilitation mangrove forest, consisting of 12 major mangroves and 6 minor mangroves. The dominant mangrove vegetation is Rhizophoramucronata with an Important Value Index on the tree class is 263.183. Substrate texture under mangrove vegetation is dominated by "sandy clays" with pH level between "acid" to "neutral" and soil fertility levels based on C-Organic content, categorized in "high levels". Water quality is included in the "good" category with an average pH level of 7.03 (neutral) and an average dissolved oxygen content (DO) of 5.12. The level of macrozoobenthic diversity categorized in the "medium" level, with the diversity index value (H) of 1.365 and the dominant species, namely Littorinascabra. The level of plankton diversity is "medium" category with a diversity index value of 1.711 with the dominant species Coscinodiscus sp.
