The HCS approach is designed to protect and restore suitable tropical forest areas within landscapes being converted for plantations, ensuring they remain safe and sustainable. This method educates land managers on how to determine forest types and make appropriate decisions about whether land can be developed or must be conserved. The approach is unique because it provides a clear stratification methodology for vegetation types for the purpose of forest conservation.
By using satellite imagery and linking it with carbon measurements in above-ground biomass, vegetation is classified into High Density Forest, Medium Density Forest, Low Density Forest, Young Regenerating Forest, Scrub, and Open Land/Bare Land. These classifications are indicated by their carbon stock value (<35 C tons/ha). Therefore, the HCS approach aims to protect the remaining tree cover in palm oil production zones and fulfill the commitment to zero deforestation.
