Struktur, Komposisi dan Potensi Stok Karbon pada Hutan Mangrove Hasil Rehabilitasi di Desa Lubuk Kertang

Abstract

Mangroves are generally distributed in tidal zones along tropical and subtropical coasts and are known as woody halophytes. Mangroves are one of the most productive and efficient long-term natural carbon sinks. Deforestation and mangrove degradation produced substantial carbon emissions that account for the majority and salt marshes emissions.. Mangroves play important roles such as protection from storms and sea level rise, prevention of coastline erosion, adjustment of coastal water quality, provision of habitat for commercially important fisheries and endangered marine species, and food security for many coastal communities. This research was conducted in a mangrove forest rehabilitating abondond of pond land in Lubuk Kertang village, West Brandan District, Langkat Regency, North Sumatra. The study measured the general variety of forest structur, composition and carbon stocks the method used was to census nondestructively by measuring the diameter, height, and type found as a whole. To calculate the value of carbon stocks, an allometric equation with DBH > 5cm was used In the mangrove forest rehabilitation area in Lubuk Kertang Village. Fourteen species were found, namely Aegiceras corniculatum, Avicennia marina, Acrostichum aureum, Bruguiera gymnorrhiza, Ceriops tagal, Excoecaria agallocha, Finlaysonia maritima, Nypa fruticans Rhizophora apiculata, Rhizophora mucronata,Rhizophora stylosa, Sonneratia alba, Scyphiphora hydrophyllacea, Sesuvium portulacastrum. The total value of the total carbon stock in above and below this mangrove was 9.42 Mg/Ha1 and carbon soil is 685 MgC/Ha1.
