ABSTRACT
Aim Our scientific understanding of the ability of various types of mangrove in absorbing carbon is inadequate. Carbon sequestration data on available mangrove species in Indonesia needs to be improved. Here, we map the data of various types of mangroves in terms of its ability to absorb carbon per hectare using previously published research data, so that it will look at the characteristics of the data available today.
Methods We collect and interpret 48 data scattered in 10 locations in Indonesia from various research results. The data then standardized based on the units that have been determined, so have an equivalent value. Furthermore, the data will be classified and analyzed according to the type of mangrove, so that the characteristics of the data can be seen.
Results These data are grouped into 21 species: Aegicera corniculatum, Avicenia lanata, Avicenia marina, Avicennia alba, Avicennia marina, Avicennia officinalis, Bruguiera cylindrica, Bruguiera gymnhoriza, Bruguiera parviflora, Ceriops decandra , Ceriops tagal, Lumnitzera, Lumnitzera littoreae, Rhizophora apiculata, Rhizophora mucronata, Rhizophora stylosa, Scyphiphora hydrophyllacea, Sonneratia alba, Sonneratia caseolaris, Xylocarpus granatum and Xylocarpus moluccensis. These data, showing significant differences in values of the same species, eg Sonneratia caseolaris has the largest range of values, ie 15 – 654 tC/ha followed by Avicennia marina 5 – 437 tC/ha and Rhizophora apiculata 0.5 – 108 tC/ha.
Main Conclusions We report that each type of mangrove has different carbon store values. From these data, there is a very significant difference in values on the same type. The largest range occurred in Sonneratia caseolaris 15-654 tC / ha, whereas the carbon calculation method used was in accordance with existing standards. This indicates that there are variables that have not been taken into account in the method of calculating carbon in mangrove that has been standard now, such as the variable of environmental characteristics and age. In addition, it also indicates that research on blue carbon is still not well consolidated.
