Atmospheric carbon dioxide has increased by more than 50% over pre-industrial levels, which has important implications for global biodiversity. Mangrove forests naturally sequester two to four times greater carbon than mature tropical forests and contains the highest carbon density of all terrestrial ecosystems. Geospatial technologies are playing an increasingly important role in mapping the structure and biophysical properties of mangroves, including biomass and carbon stocks, while increasing the range of analysis, lowering expenses, and increasing efficiency compared to typical field surveys. The objectives of this study were to estimate above and belowground carbon stock of mangrove forests utilizing geospatial technologies and publicly available data. High-resolution multispectral and LiDAR data was used for geographic object-based image analysis of mangrove forests to derive mangrove forest stands. We estimated the total mangrove carbon stock for our study area of 225 ha within the Everglades National Park to be 277.45 Mg/ha.
