Methodology

• Structure community of Seagrass : McKenzie et al, 2003

• Structure community of Mangrove : Bengen, 2003; Kauffman & Donato, 2012

• Biomass & karbon stok estimation: Kauffman & Donato, 2012

Mangrove Biomass Allometric Equations

Sonneratia alba : B = 0.3841(D)2.101*ρ (Kauffman & Donato, 2012)

Rhizophora stylosa : B = 0.105 (D)2.68 (Clough and Scott,1989)

Rhizophora mucronata : B = 0.128(D)2.60 (Fromard et al, 1998)

Bruguiera gymnorhiza : B = 0.0754D2.505*ρ (Clough and Scott,1989)

Aegiceras floridum : B = 0.251 ρ (D)2.46 (Komiyama et al. 2005)
