Spatial pattern of carbon mangrove stock based on habitat characteristics in Bali Province

Abstract

Although climate change mitigation regarding mangrove forest management has been given significant international attention during the past decade, there are no sufficiently reliable data to quantify the availability of carbon stock in mangrove forests. The mangrove forest in the Bali Province is divided into three habitat types, namely an open bay located in the West Bali National Park, a semi-closed bay located in Tahura Ngurah Rai and a small island in the protected forest of Nusa Lembongan. The objective of this study is to analyse the relationship between carbon stock characteristics of mangrove forests with the different types and morphologies of mangrove forest habitats. Biomass calculations were carried out by using the allometric formula. However, the similar allometric equations produced varying accuracies at different locations. Results revealed that the mangrove forest carbon stock for the semi-closed bay habitat has the highest estimation value of 51.35 tons/ha and a positive relationship pattern of 60 %. On the contrary, the lowest carbon stock value is the open bay beach with a value 26.28 tons/ha and positive relationship pattern of 48 %. This study reveals that each type of mangrove forest habitat has its own living ecosystem characteristics that affect the carbon stock value.
