Abstract

Abstract. Yulma, Adiwilaga EM, Wardiatno Y. 2013. Contribution of organic material from white mangrove (Avicennia marina) to evaluate mangrove ecosystem management: Case Study of Labuhan Maringgai, East Lampung. Bonorowo Wetlands 3: 12-29. The purpose of this study was to determine the potential contribution of organic matter (C, N, and P) of mangrove forest litter production in Labuhan Maringgai, East Lampung, to the marine environment, as well as evaluate the mangrove rehabilitation program conducted by the Lampung Mangrove Center program of the University of Lampung, Bandar Lampung. Lampung Mangrove Center (LMC) provides litter productivity of 4.53 g/m²/day with the most significant contributor from leaf litter and twigs, while flowers and fruit are not found. The dry weight of the remaining mangrove leaf litter on day 56 ranged between 5-2.5 g. LMC has the potential production of organic material that can be used litter amounted to 0.76164 GC/m²/day; 0.00628 GN/m²/day; 0.00331 GP/m²/day. Mangrove rehabilitation involving three parties, including the Government of East Lampung District, University of Lampung, and the community, is very effective in conserving mangrove forests in LMC within 1,000 ha of mangrove ranges.
