The Mangrove Density, Diversity, and Environmental Factors as Important Variables to Support the Conservation Program of Essential Ecosystem Area in Muara Kali Ijo, Pantai Ayah, Kebumen

The planning of wetland essential ecosystem area (EEA) conservation and preservation activities is important to support stability, including the mangrove ecosystem. These should consider ecological, economic, social aspects. This study aimed analyze indicator program EEA in Muara Kali Ijo, Pantai Ayah, Kebumen. research method used mapping analysis using density, diversity, environmental indicators. results showed that density Ijo was 1,500-4,300 trees/ha (moderate very dense) dominated by Rhizophora mucronata styllosa. potential total dissolved solids, water salinity, hydrogen, oxygen, biological oxygen demand, nitrate had a good condition mangrove’s life growth. also activity conserve preserve Crocodylus porosus. developed 18.5 ha, divided into five zones: 5.90 utilization 6.40 arboretum 4.40 rehabilitation 1.30 specific 0.5 ha. has value preserving from coastal disaster increasing economic with tourism other activities.
