Abstract

The Segara Ankan Lagoon (SAL) has a potentially reduced mangrove ecosystem. In this year, the mangrove area in SAL is predicted only remaining 1788 ha. The degradation of The Segara Ankan Lagoon (SAL) has a potentially reduced mangrove ecosystem. In this year, the mangrove area in SAL is predicted only remaining 1788 ha. The degradation of mangrove ecosystem often occurres in SAL, especially in Eastern of Segara Anakan Lagoon Cilacap (E-SAL). To reduce mangrove degradation need activities to review their status and recovery activities. This research aims to analysis the activities to support the effort of mangrove rehabilitation. The results of this researchd showed that (1) The potential of mangrove ecosystem in E-SAL was seedling between 15.000 – 34.999 trees ha-1, sapling between 5.199-9.065 trees ha-1 and trees between 533 – 1366 trees ha-1, (2) The status of mangrove ecosystem in E-SAL was damaged – very damaged. (3) the model spesices selection of rehabilitation pattern to reduce mangrove degradation were Rhizophora apiculata, Rhizophora mucronata, Aegiceras corniculatum, Sonneratia alba, Avicennia marina, and Bruguiera gymnorrhiza

Highlights

  • The Eastern Segaara Anakn Lagoon (E-Segara Ankan Lagoon (SAL)) is part of Segara Anakan Lagoon Cilacap which has characterize as spesific eustary and mangrove ecosystem (Hilmi et al, 2017a., Hilmi et al, 2017c) and as eustary form rivers namely Donan, Sapuregel and Kembang Kuning rivers which has deep water between 5 m -10 m (Hilmi et al, 2015)

  • The Eastern Segara Anakan Lagoon is influenced by seawater and freshwater which give possibility of mangrove vegetation to grow up in Segara Anakan Lagoon as a ecosystem (Nursid, 2002; Hilmi et al, 2019a)

  • The potential of mangrove ecosystem in ESAL is composed by the mangrove vegetations to develop mangrove zones base on tha adaptation pattern, association, sea water inundation, sea tide, and potential of biodiversity to reach the stability of

Summary

Introduction

The Eastern Segaara Anakn Lagoon (E-SAL) is part of Segara Anakan Lagoon Cilacap which has characterize as spesific eustary and mangrove ecosystem (Hilmi et al, 2017a., Hilmi et al, 2017c) and as eustary form rivers namely Donan, Sapuregel and Kembang Kuning rivers which has deep water between 5 m -10 m (Hilmi et al, 2015). Mangrove ecosystem in E-SAL has spesific vegetation can be classified base on the tolerance level of wter salinity and the inundation of seawater in mngrove ecosystem and coastal ecosystem (Kolinug et al, 2014). The degradation of mangrove ecosystem must have effort to rehabiltate mangrove ecosystem with recovery, rehabilitation and replanting activity (Barbier, 2018), develop mangrove landscaping (Hilmi, 2018) base on the patern of mangrove adaptation and community preception to restore and rehabilitate mangrove ecosystem. The rehabilitation activity of mangrove ecosystem and mangrove replanting are showed to regrowth, restore and rehabilitate mangrove ecosystem to reach mangrove climax (Kusmana, 2005) This paoper aims to analyss the status of mangrove ecosystem in E-SAL and species selection to develop the rehabilitation effort of mngrove ecosystem in E-SAL. Research Procedures The research procedure wa conducted with two stages that were :

Mangrove sampling
Species selection to support rehabilitation and recovery of mangrove ecosystem
