Model Specifics

Maps of nearshore marine veg.

Amt. stored in 4 carbon ‘pools’• Aboveground biomass• Belowground biomass• Sediments• Dead organic matter

Rate of carbon accumulation in sediments for each veg. type

Market or social value of seq. carbon

Annual rate of change and a discount rate

Carbon storage (Mg C/ha)

Carbon sequestration (Mg C/ha/yr)

Economic value of carbon storage and sequestration

InVEST Blue Carbon model

Estimates: • How much carbon is stored in coastal vegetation and sediments• Carbon accumulation in the sediments• Economic value of storage and sequestration
